• How to split a string with negative numbers using ActionScript 3.0

  - by inzombiak

  I'm having trouble loading my level. I'm using Ogmo to create my level then I import it. I have no problem converting 0's and 1's into an Array, but I can't figure out how to do the same for -1's. It separates the "-" and the "1". Any help would be great. I've posted my code and the XML files below levelXML = new XML(e.target.data); playerX = int(levelXML.Entities.Player.@x); playerY = int(levelXML.Entities.Player.@y); levelGrid = levelXML.Grid; levelGrid = levelGrid.split("\n").join(""); levelTiles = levelXML.Tiles; levelTiles = levelTiles.split("\n").join(""); levelTiles = levelTiles.split(",").join(""); tileArray = levelTiles.split(""); gridArray = levelGrid.split(""); for(i = 0; i <= 34; i++) { levelArray[i] = new Array(); for(j = 0; j <= 34; j++) { if(tileArray[j*35 + i] == 0) { gridArray[j*35+i] = -1; } var currentSymbol = gridArray[j*35+i]; levelArray[i][j] = currentSymbol; if(gridArray[j*35 + i] == 1) { wall = new Wall; addChild(wall); wall.x = i*20 + 10; wall.y = j*20 + 10; } else if(gridArray[j*35 + i] == -1) { pellet = new Pellet; addChild(pellet); pellet.x = i*20 + 10; pellet.y = j*20 + 10; } } } I know the code is very dirty, but I needed a quick fix.

• A* PathFinding Poor Performance

  - by RedShft

  After debugging for a few hours, the algorithm seems to be working. Right now to check if it works i'm checking the end node position to the currentNode position when the while loop quits. So far the values look correct. The problem is, the farther I get from the NPC, who is current stationary, the worse the performance gets. It gets to a point where the game is unplayable less than 10 fps. My current PathGraph is 2500 nodes, which I believe is pretty small, right? Any ideas on how to improve performance? struct Node { bool walkable; //Whether this node is blocked or open vect2 position; //The tile's position on the map in pixels int xIndex, yIndex; //The index values of the tile in the array Node*[4] connections; //An array of pointers to nodes this current node connects to Node* parent; int gScore; int hScore; int fScore; } class AStar { private: SList!Node openList; SList!Node closedList; //Node*[4] connections; //The connections of the current node; Node currentNode; //The current node being processed Node[] Path; //The path found; const int connectionCost = 10; Node start, end; ////////////////////////////////////////////////////////// void AddToList(ref SList!Node list, ref Node node ) { list.insert( node ); } void RemoveFrom(ref SList!Node list, ref Node node ) { foreach( elem; list ) { if( node.xIndex == elem.xIndex && node.yIndex == elem.yIndex ) { auto a = find( list[] , elem ); list.linearRemove( take(a, 1 ) ); } } } bool IsInList( SList!Node list, ref Node node ) { foreach( elem; list ) { if( node.xIndex == elem.xIndex && node.yIndex == elem.yIndex ) return true; } return false; } void ClearList( SList!Node list ) { list.clear; } void SetParentNode( ref Node parent, ref Node child ) { child.parent = &parent; } void SetStartAndEndNode( vect2 vStart, vect2 vEnd, Node[] PathGraph ) { int startXIndex, startYIndex; int endXIndex, endYIndex; startXIndex = cast(int)( vStart.x / 32 ); startYIndex = cast(int)( vStart.y / 32 ); endXIndex = cast(int)( vEnd.x / 32 ); endYIndex = cast(int)( vEnd.y / 32 ); foreach( node; PathGraph ) { if( node.xIndex == startXIndex && node.yIndex == startYIndex ) { start = node; } if( node.xIndex == endXIndex && node.yIndex == endYIndex ) { end = node; } } } void SetStartScores( ref Node start ) { start.gScore = 0; start.hScore = CalculateHScore( start, end ); start.fScore = CalculateFScore( start ); } Node GetLowestFScore() { Node lowest; lowest.fScore = 10000; foreach( elem; openList ) { if( elem.fScore < lowest.fScore ) lowest = elem; } return lowest; } //This function current sets the program into an infinite loop //I still need to debug to figure out why the parent nodes aren't correct void GeneratePath() { while( currentNode.position != start.position ) { Path ~= currentNode; currentNode = *currentNode.parent; } } void ReversePath() { Node[] temp; for(int i = Path.length - 1; i >= 0; i-- ) { temp ~= Path[i]; } Path = temp.dup; } public: //@FIXME It seems to find the path, but now performance is terrible void FindPath( vect2 vStart, vect2 vEnd, Node[] PathGraph ) { openList.clear; closedList.clear; SetStartAndEndNode( vStart, vEnd, PathGraph ); SetStartScores( start ); AddToList( openList, start ); while( currentNode.position != end.position ) { currentNode = GetLowestFScore(); if( currentNode.position == end.position ) break; else { RemoveFrom( openList, currentNode ); AddToList( closedList, currentNode ); for( int i = 0; i < currentNode.connections.length; i++ ) { if( currentNode.connections[i] is null ) continue; else { if( IsInList( closedList, *currentNode.connections[i] ) && currentNode.gScore < currentNode.connections[i].gScore ) { currentNode.connections[i].gScore = currentNode.gScore + connectionCost; currentNode.connections[i].hScore = abs( currentNode.connections[i].xIndex - end.xIndex ) + abs( currentNode.connections[i].yIndex - end.yIndex ); currentNode.connections[i].fScore = currentNode.connections[i].gScore + currentNode.connections[i].hScore; currentNode.connections[i].parent = &currentNode; } else if( IsInList( openList, *currentNode.connections[i] ) && currentNode.gScore < currentNode.connections[i].gScore ) { currentNode.connections[i].gScore = currentNode.gScore + connectionCost; currentNode.connections[i].hScore = abs( currentNode.connections[i].xIndex - end.xIndex ) + abs( currentNode.connections[i].yIndex - end.yIndex ); currentNode.connections[i].fScore = currentNode.connections[i].gScore + currentNode.connections[i].hScore; currentNode.connections[i].parent = &currentNode; } else { currentNode.connections[i].gScore = currentNode.gScore + connectionCost; currentNode.connections[i].hScore = abs( currentNode.connections[i].xIndex - end.xIndex ) + abs( currentNode.connections[i].yIndex - end.yIndex ); currentNode.connections[i].fScore = currentNode.connections[i].gScore + currentNode.connections[i].hScore; currentNode.connections[i].parent = &currentNode; AddToList( openList, *currentNode.connections[i] ); } } } } } writeln( "Current Node Position: ", currentNode.position ); writeln( "End Node Position: ", end.position ); if( currentNode.position == end.position ) { writeln( "Current Node Parent: ", currentNode.parent ); //GeneratePath(); //ReversePath(); } } Node[] GetPath() { return Path; } } This is my first attempt at A* so any help would be greatly appreciated.

• Why does my MacBook Pro have long ping times over Wi-Fi?

  - by randynov

  I have been having problems connecting with my Wi-Fi. It is weird, the ping times to the router (<30 feet away) seem to surge, often getting over 10 seconds before slowly coming back down. You can see the trend below. I'm on a MacBook Pro and have done the normal stuff (reset the PRAM and SMC, changed wireless channels, etc.). It happens across different routers, so I think it must be my laptop, but I don't know what it could be. The RSSI value hovers around -57, but I've seen the transmit rate flip between 0, 48 and 54.

• Need help diagnosing network performance issues

  - by tokes

  I am currently working in a developing country as a system analyst for a government department. My area of expertise is software projects, but I've come across a few issues with the network setup in my office. (Unfortunately, being a developing country, there's not a lot of professional help available for this sort of thing.) Most recently, I am trying to diagnose a problem with slowness on the network. Our office is connected to the internet via an ADSL wireless modem/router (called Router). The modem is connected via ethernet to a switch (called Switch). The modem also acts as a wireless access point (called Wireless1), though because it is in a room at the end of the floor, it's range is limited. There are ethernet ports installed around the office. The cables of these all lead back to the same switch. In closer vicinity to the bulk of the client computers, there is another wireless router that acts as an access point for those clients (called Wireless2). That router is connected via ethernet to a wall port, and therefore to Switch. There is also a Windows server which acts as a DNS server (called DNSBox) which is located in the same room and is connected directly to Switch. ---Internet----------| Router/Wireless1 192.168.10.1 ---------------| |----|=========| DNSBox | |-------------------- 192.168.10.4 --------------------| Switch |---Other clients---- | |-------------------- |----|=========| Wireless2 ------------------| 192.168.10.198 One final thing to mention about the network setup. All clients are configured with manual IP addresses. Their router/gateway is set to the IP address of Router, and their DNS server is set to the IP address of DNSBox (with a secondary IP set to an external IP - that of our ISP's DNS server). Here are the symptoms we are experiencing: Clients connected to Wireless2 AP experience slow and unstable connections to the internet. (Slow here is defined as speeds of ~1KB/s, though ping response times seem to be as normal.) Clients connected via ethernet to Switch also experience the same slowness. Clients connected to Wireless1 AP (i.e. connecting via wireless directly to the ADSL modem) experience normal connections to the internet. Clients connected via ethernet to Router (i.e. connecting via ethernet directly to the ADSL modem) also experience normal connections to the internet. I also tried to gauge the connection performance between two machines on the network via ethernet: A file transfer between two clients who were both directly connected to Switch was the fastest; A file transfer between one client directly connected to Switch, and one client directly connected to Router (which is directly connected to Switch) performed much slower; A file transfer between two clients directly connected to Router also performed slowly. Things I have attempted to diagnose the problem: Restarted Switch -- no change. We tried unplugging ethernet jacks from Switch 4 at a time and testing the internet connection. The thought here was that perhaps a client on the network has contracted a virus, and is possibly spamming the network with traffic? (Not very technical, I know.) Unfortunately we couldn't get any significant increases in performance using this method. There were a couple of times when it seemed to be better, but then the connection speed quickly dropped back to slow/dead pace. I didn't want to unplug all jacks from Switch because I was concerned that users might be affected or that I would re-plug in the jacks incorrectly (should I even be worried about that? a port is a port on a switch, right?) I tried swapping the ethernet cable used to connect Router to Switch -- no change in performance. I tried swapping the port used on Switch for Router -- no change in performance. Anyone got any ideas on what this could be? Should I be mentioning specific brand names/models of the hardware used? Virii outbreaks are common in this country/office -- what could I be doing to figure out if a virus is at fault? If it is a virus, it doesn't seem to be generating a lot of traffic to/from the internet, because a) I can still get a good speed if I am directly connected to Router / Wireless1 and b) our ISP data usage has not risen suspiciously. Thanks for your help! Update #1 Here are the specs of some of the hardware: Switch is an Edimax ES3132RL 32-Port 10/100 Rackmount Switch Router is a D-Link DSL-G604T Update #2 I just tried unplugging everything except a laptop and Router from Switch. Speeds are still slow. I guess that means that Router / Switch are not being flooded? It seems more and more likely that the cause is something to do with the interaction between Router and Switch. However, I still can't find any useful resources on setting the LAN speed for either (and I'm not well-versed in these advanced networking configurations).

• Why does this mod_rewrite rule 'not-match'? (big rewrite log included)

  - by Christopher

  I've got a scenario involving two domains: WordPress site hosted on domain1.com domain2.co.uk, simply redirecting users to domain1 via mod_rewrite This rule applies irrespective of whether www. is specified or not. (It's eventually removed from the URL, I'm a no-WWW fan.) There's nothing on domain2.co.uk at all except for an .htaccess with some mod_rewrite rules. However, I want to be able to allow users to be redirected to the correct article URI even if they specify the "wrong" URL (i.e., a 301 redirect preserving the stuff after the first forward slash). I'm currently achieving this with this ruleset: RewriteCond %{HTTP_HOST} ^((www\.)?[^\.]+)\.domain2\.co\.uk [NC,OR] RewriteCond %{HTTP_HOST} ^domain2\.co\.uk [NC] RewriteRule ^(.*)$ http://domain1.com/$1 [R=301,L] This works but is uglier than I want it to be. I'm not a mod_rewrite zen master, but from what I can tell the top rule should match irrespective of whether www. is specified... But it doesn't. In order to catch www-less requests, I need the second RewriteCond. From the rewrite log, with just the first RewriteCond: [domain2.co.uk/sid#e200498][rid#e670168/initial] (3) [perdir /home/devnull/domains/domain2.co.uk/public_html/] strip per-dir prefix:

• Cisco PIX 8.0.4, static address mapping not working?

  - by Bill

  upgrading a working Pix running 5.3.1 to 8.0.4. The memory/IOS upgrade went fine, but the 8.0.4 configuration is not quite working 100%. The 5.3.1 config on which it was based is working fine. Basically, I have three networks (inside, outside, dmz) with some addresses on the dmz statically mapped to outside addresses. The problem seems to be that those addresses can't send or receive traffic from the outside (Internet.) Stuff on the DMZ that does not have a static mapping seems to work fine. So, basically: Inside - outside: works Inside - DMZ: works DMZ - inside: works, where the rules allow it DMZ (non-static) - outside: works But: DMZ (static) - outside: fails Outside - DMZ: fails (So, say, udp 1194 traffic to .102, http to .104) I suspect there's something I'm missing with the nat/global section of the config, but can't for the life of me figure out what. Help, anyone? The complete configuration is below. Thanks for any thoughts! !

• Hyper-V File Server Clustering - at my wit’s end

  - by René Kåbis

  I am at my wit’s end with File Server clustering under Hyper-V. I am hoping that someone might be able to help me figure out this Gordian Knot of a technology that seems to have dead ends (like forcing cluster VMs to use iSCSI drives where normally-attached VHDX drives could suffice) where logic and reason would normally provide a logical solution. My hardware: I will be running three servers (in the end), but right now everything is taking place on one server. One of the secondary servers will exist purely as a witness/quorum, and another slightly more powerful one will be acting as an emergency backup (with additional storage, just not redundant) to hold the secondary AD VM and the other halves of a set of clustered VMs: the SQL VM and the file system VM. Please note, these each are the depreciated nodes of a cluster, the main nodes will be on the most powerful first machine. My heavy lifter is a machine that also contains all of the truly redundant storage on the network. If this gives anyone the heebie-geebies, too bad. It has a 6TB (usable) RAID-10 array, and will (in the end) hold the primary nodes of both aforementioned clusters, but is right now holding all VMs. This is, right now: DC01, DC02, SQL01, SQL02, FS01 & FS02. Eventually, I will be adding additional VMs to handle Exchange, Sharepoint and Lync, but only to this main server (the secondary server won't be able to handle more than three or four VMs, so why burden it? The AD, SQL & FS VMs are the most critical for the business). If anyone is now saying, “wait, what about a SAN or a NAS for the file servers?”, well too bad. What exists on the main machine is what I have to deal with. I followed these instructions, but I seem to be unable to get things to work. In order to make the file server truly redundant, I cannot trust any one machine to hold the only data store on the network. Therefore, I have created a set of iSCSI drives on the VM-host of the main machine, and attached one to each file server VM. The end result is that I want my FS01 to sit on the heavy lifter, along with its iSCSI “drive”, and FS02 will sit on the secondary machine with its own iSCSI “drive” there as well. That is, neither iSCSI drive will end up sitting on the same machine as the other. As such, the clustered FS will utterly duplicate the contents of the iSCSI drives between each other, so that if one physical machine (or the FS VM) goes toes-up, the other has got a full copy of the data on its own iSCSI drive. My problem occurs when I try to apply the file server role within the failover cluster manager. Actually, it is even before that -- it occurs when adding the disks. Since I have added each disk preferentially to a specific VM (by limiting the initiator by DNS hostname, and by adding two-way CHAP authentication), this forces each VM to be in control of its own iSCSI disk. However, when I try to add the disks to the Disks section of Storage within Failover Cluster Manager, the entire process fails for a random disk of the pair. That is, one will get online, but the other will remain offline because it does not have the correct “owner node”. I mean, really -- WTF? Of course it doesn’t have the right owner node, both drives are showing the same node name!! I cannot seem to have one drive show up with one node name as owner, and the other drive show up with the other node name as owner. And because both drives are not “online”, I cannot create a pool to apply to a cluster role. Talk about getting stuck between a rock and a hard place! I’ve got more to add, but my work is closing for the day and I have to wrap things up. I will try to add more tomorrow morning when I get in. My main objective is to have a file server VM on each machine, the storage on each machine, but a transparent failover in case one physical machine fails. Essentially, a failover FS that doesn’t care which machine fails -- the storage contents are replicated equally on each machine. Am I even heading in the right direction?

• Linux IPTables / routing issue

  - by Jon

  Hi all, EDIT 1/3/10 22:00 GMT - rewrote some of it after further investigation It has been a while since I looked at IPtables and I seem to be worse than before as I can not seem to get my webserver online. Below is my firewall rules on the gateway server that is running the dhcp server accessing the net. The webserver is inside my network on a static IP (192.168.0.98, default port). When I use Nmap or GRC.com I see that port 80 is open on the gateway server but when I browse to it, (via public URL. http://www.houseofhawkins.com) it always fails with a connection error, (nmap cannot connect and figure out what the web server is either). I can nmap the webserver and browse to it just fine via same IP inside my network. I believe it is my IPTable rules that are not letting it through. Internally I can route all my requests. Each machine can browse to the website and traffic works just fine. I can MSTSC / ssh to all the webservers internally and they inturn can connect to the web.

The network looked something like this: I have now replaced the sky modem with a dlink modem which gives the IP to the gateway server that now does the DHCP. It looks like: The internet connection is a standard broadband connection with a dynamic IP, (use zoneedit.com to keep it updated). I have tried it on each of the webservers(one Ubuntu Apache server and one WS2008 IIS7). I think there must also be an issue with my IPTable rules as it can route to my win7 box which has the default IIS7 page and that would not display when I forwarded all port 80 to it. I would be really grateful for any and all help with this. Thanks Jon

• Why does my macbook pro have long ping times over wifi?

  - by randynov

  I have been having problems connecting with my wifi. It is weird, the ping times to the router (<30 feet away) seem to surge, often getting over 10s before slowly coming back down. You can see the trend below. I'm on a macbook pro and have done the normal stuff (reset the pram and smc, changed wireless channels, etc.). It happens across different routers, so I think it must be my laptop, but I don't know what it could be. The RSSI value hovers around -57, but I've seen the transmit rate flip between 0, 48 & 54. The signal strength is ~60% with 9% noise. Currently, there are 17 other wireless networks in range, but only one in the same channel. 1 - How can I figure out what's going on? 2 - How can I correct the situation? TIA!

• howto only tunnel specific hosts route through openvpn client on tomato

  - by kcome

  I am relatively newbie in networking world although I did coding and know some sysadmin background for a long time. and here I'm only one step from my destination. The whole picture is : at home I use one LinkSys E3000 as the gateway(don't know yet if this is it's name), wireless AP and no other routing/switching devices. It serves 1 PC and 1 Mac with LAN, 1 Mac Mini + 1 iPad + 2 smartphones with WIFI. My goal is use an openvpn client on the E3000 (with tomato firmware) and make my iPad and smartphone's all WiFi traffic through it, and other devices route remain the same non-openvpn route. So far I'm able to connect openvpn client on E3000 to an openvpn server, tunnel all my devices' all traffic through that openvpn connection. What's left is howto selectively route by source IP (at least in my guessing) to the tunnel while don't bother others. I had learned some 'iptables' and 'route' in past few days however without much luck, so here comes my question. Here are some info which will help you get the structure. ifconfig -a output, some useless lines striped, and in the web interface C0:C1:C0:1A:E0:28 is WAN, C0:C1:C0:1A:E0:27 is LAN, C0:C1:C0:1A:E0:29 is 2.4G wifi AP, C0:C1:C0:1A:E0:2A is 5G wifi AP. root@router:/tmp/home/root# ifconfig -a br0 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:27 inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 eth0 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:27 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 eth1 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:29 UP BROADCAST RUNNING ALLMULTI MULTICAST MTU:1500 Metric:1 eth2 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:2A UP BROADCAST RUNNING ALLMULTI MULTICAST MTU:1500 Metric:1 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host ppp0 Link encap:Point-to-Point Protocol inet addr:172.200.1.43 P-t-P:172.200.0.1 Mask:255.255.255.255 UP POINTOPOINT RUNNING MULTICAST MTU:1480 Metric:1 vlan1 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:27 UP BROADCAST RUNNING ALLMULTI MULTICAST MTU:1500 Metric:1 vlan2 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:28 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 wl0.1 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:29 BROADCAST MULTICAST MTU:1500 Metric:1 brctl show output root@router:/tmp/home/root# brctl show bridge name bridge id STP enabled interfaces br0 8000.c0c1c01ae027 no vlan1 eth1 eth2 before openvpn route-up script root@router:/tmp/home/root# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.200.0.1 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 br0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 172.200.0.1 0.0.0.0 UG 0 0 0 ppp0 openvpn server push PUSH: Received control message: 'PUSH_REPLY,redirect-gateway,dhcp-option DNS 8.8.8.8,route 172.20.0.1,topology net30,ping 10,ping-restart 120,ifconfig 172.20.0.6 172.20.0.5' openvpn's stock route-up script Apr 24 14:52:06 router daemon.notice openvpn[1768]: /sbin/ifconfig tun11 172.20.0.6 pointopoint 172.20.0.5 mtu 1500 Apr 24 14:52:08 router daemon.notice openvpn[1768]: /sbin/route add -net 72.14.177.29 netmask 255.255.255.255 gw 172.200.0.1 Apr 24 14:52:08 router daemon.notice openvpn[1768]: /sbin/route add -net 0.0.0.0 netmask 128.0.0.0 gw 172.20.0.5 Apr 24 14:52:08 router daemon.notice openvpn[1768]: /sbin/route add -net 128.0.0.0 netmask 128.0.0.0 gw 172.20.0.5 Apr 24 14:52:08 router daemon.notice openvpn[1768]: /sbin/route add -net 172.20.0.1 netmask 255.255.255.255 gw 172.20.0.5 route after openvpn root@router:/tmp/home/root# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.20.0.5 0.0.0.0 255.255.255.255 UH 0 0 0 tun11 72.14.177.29 172.200.0.1 255.255.255.255 UGH 0 0 0 ppp0 172.200.0.1 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 172.20.0.1 172.20.0.5 255.255.255.255 UGH 0 0 0 tun11 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 br0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 172.20.0.5 128.0.0.0 UG 0 0 0 tun11 128.0.0.0 172.20.0.5 128.0.0.0 UG 0 0 0 tun11 0.0.0.0 172.200.0.1 0.0.0.0 UG 0 0 0 ppp0 something I had noticed and tried: * on the web interface of openvpn client there is an option "Create NAT on tunnel", if i check this, there is the following script (probably executed after openvpn connection established) root@router:/tmp/home/root# cat /tmp/etc/openvpn/fw/client1-fw.sh #!/bin/sh iptables -I INPUT -i tun11 -j ACCEPT iptables -I FORWARD -i tun11 -j ACCEPT iptables -t nat -I POSTROUTING -s 192.168.1.0/255.255.255.0 -o tun11 -j MASQUERADE if i uncheck this option, the last line will not appear.

• Segmentation Fault (11) with modwsgi on CentOS 5.7 when running pyramid app

  - by carbotex

  I'm getting Segmentation fault error when trying to access the "Hello World" pyramid app. This error only occurs when running against CentOS 5.7 setup, but no problem whatsoever when tested against OSX and Arch Linux. Could it be a CentOS specific issue? [error] [client 10.211.55.2] Premature end of script headers: pyramid.wsgi [notice] child pid 31212 exit signal Segmentation fault (11) I have tried to follow the troubleshooting guides posted here http://code.google.com/p/modwsgi/wiki/InstallationIssues which suggests that it might caused by missing Shared Library. A quick check reveals that shared library is not the issue.

• LDAP query on linux against AD returns groups with no members

  - by SethG

  I am using LDAP+kerberos to authenticate against Active Directory on Windows 2003 R2. My krb5.conf and ldap.conf appear to be correct (according to pretty much every sample I found on the 'net). I can login to the host with both password and ssh keys. When I run getent passwd, all my ldap user accounts are listed with all the important attributes. When I run getent group, all the ldap groups and their gid's are listed, but no group members. If I run ldapsearch and filter on any group, the members are all listed with the "member" attribute. So the data is there for the taking, it's just not being parsed properly. It would appear that I simply am using an incorrect mapping in ldap.conf, but I can't see it. I've tried several variations and all give the same result. Here is my current ldap.conf: host <ad-host1-ip> <ad-host2-ip> base dc=my,dc=full,dc=dn uri ldap://<ad-host1> ldap://<ad-host2> ldap_version 3 binddn <mybinddn> bindpw <mybindpw> scope sub bind_policy hard nss_reconnect_tries 3 nss_reconnect_sleeptime 1 nss_reconnect_maxsleeptime 8 nss_reconnect_maxconntries 3 nss_map_objectclass posixAccount User nss_map_objectclass posixGroup Group nss_map_attribute uid sAMAccountName nss_map_attribute gidNumber msSFU30GidNumber nss_map_attribute uidNumber msSFU30UidNumber nss_map_attribute cn cn nss_map_attribute gecos displayName nss_map_attribute homeDirectory msSFU30HomeDirectory nss_map_attribute loginShell msSFU30LoginShell nss_map_attribute uniqueMember member pam_filter objectcategory=User pam_login_attribute sAMAccountName pam_member_attribute member pam_password ad Here's the kicker: this config works 100% fine on a different linux box with a different distro. It does not work on the distro I am planning on switching to. I have installed from source the versions of pam_ldap and nss_ldap on the new box to match the old box, which fixed another problem I was having with this setup. Other relevant info is the original AD box was Windows 2003. It's mirror died a horrible hardware death so I'm trying to add two more 2003-R2 servers to the mirror tree and ultimately drop the old 2003 box. The new R2 boxes appear to have joined the DC forest properly. What do I need to do to get groups working? I've exhausted all the resources I could find and need a different angle. Any input is appreciated. Status update, 7/31/09 I have managed to tweak my config file to get full info from the AD and performance is nice and snappy. I replaced the back-rev'd copies of pam_ldap and nss_ldap with the current ones for the distro I'm using, so it's back to a standard out-of-the-box install. Here's my current config: host <ad-host1-ip> <ad-host2-ip> base dc=my,dc=full,dc=dn uri ldap://<ad-host1> ldap://<ad-host2> ldap_version 3 binddn <mybinddn> bindpw <mybindpw> scope sub bind_policy soft nss_reconnect_tries 3 nss_reconnect_sleeptime 1 nss_reconnect_maxsleeptime 8 nss_reconnect_maxconntries 3 nss_connect_policy oneshot referrals no nss_map_objectclass posixAccount User nss_map_objectclass posixGroup Group nss_map_attribute uid sAMAccountName nss_map_attribute gidNumber msSFU30GidNumber nss_map_attribute uidNumber msSFU30UidNumber nss_map_attribute cn cn nss_map_attribute gecos displayName nss_map_attribute homeDirectory msSFU30HomeDirectory nss_map_attribute loginShell msSFU30LoginShell nss_map_attribute uniqueMember member pam_filter objectcategory=CN=Person,CN=Schema,CN=Configuration,DC=w2k,DC=cis,DC=ksu,DC=edu pam_login_attribute sAMAccountName pam_member_attribute member pam_password ad ssl off tls_checkpeer no sasl_secprops maxssf=0 The remaining problem now is when you run the groups command, not all subscribed groups are listed. Some are (one or two), but not all. Group memberships are still honored, such as file and printer access. getent group foo still shows that the user is a member of group foo. So it appears to be a presentation bug, and does not interfere with normal operation. It also appears that some (I have not determined exactly how many) group searches do not resolve correctly, even though the group is listed. eg, when you run "getent group bar", nothing is returned, but if you run "getent group|grep bar" or "getent group|grep <bar_gid>" you can see that it indeed listed and your group name and gid are correct. This still seems like an LDAP search or mapping error, but I can't figure out what it is. I'm a heckuva lot closer than earlier in the week, but I'd really like to get this last detail ironed out.

• All downloads being interrupted

  - by Jake

  System: Windows 7 Professional 64bit. 8GB RAM, Intel i5-2400 CPU, +300GB free on the hard drive. AVG Internet Security 2012 (enabled & disabled, with firewall enabled and disabled - no effect for either). This computer is less than a year old. Network: This problem is occurring on a single computer on a network with multiple computers. The router is a Motorola Netopia 3347-02 (DSL Modem/Wireless Router combined). The computer is plugged in directly to the modem, other computers are using the wireless successfully. The router has been reset. The only thing odd about the connection between the router and computer is that it is configured to allow RDP through, so it is assigned a static IP by the router and port forwarding is enabled for port 3389. Also, though I doubt it matters, a second wireless router is active behind this router providing a second network that some computers in the area use without issues. Details: All downloads initiated on this specific computer eventually fail, this includes streaming from youtube, specialized downloads (itunes), downloads from websites, FTP downloads, etc. Failure occurs with all browsers, but in chrome this is the process it takes: 1) Download begins normally, 2) At some point between (observed) 7MBs and 229MBs the download stops progressing (at this point, if watching chrome's task manager, you can see the network activity for the downloading tab drop to 0kps), 3) for some time the download sits there still attempting to complete, but will eventually display "123,049,871/0 B, Interrupted" (where the number is whatever it actually got to). The file I am using to test this is a very large .zip file located on a server I control, but the problem seems to occur on any site. The amount downloaded is completely random, and seems to be more time-based than anything (if I start a download immediately after the last one fails, it tends to get further than the last one). Small files can get through for this reason, though they can fail as well. In a test where I simultaneously downloaded the same file via HTTP (chrome) and FTP (windows explorer), both downloads failed at the same instant, though explorer displayed "Connection timed out" several minutes before chrome finally showed the download as interrupted. Other things I have tried based on advice given to people with similar/identical problems: Setting my MTU to 1492 (as described here: http://blog.thecompwiz.com/2011/08/networking-issues.html) Disabling write caching to the hard drive storing the download on an external device successfully transmitted +1GB file from one computer on the same network to this computer disabling indexing in the folder the download was being stored in disabling all security software checked to make sure all drivers were up to date read about 50 accounts with nearly exact descriptions of what I'm experiencing, none of which had a solution given Running Processes: Image Name PID Session Name Session# Mem Usage ========================= ======== ================ =========== ============ System Idle Process 0 Services 0 24 K System 4 Services 0 104,836 K smss.exe 332 Services 0 1,276 K csrss.exe 764 Services 0 5,060 K wininit.exe 820 Services 0 4,748 K csrss.exe 844 Console 1 23,764 K services.exe 876 Services 0 11,856 K lsass.exe 892 Services 0 14,420 K lsm.exe 900 Services 0 7,820 K winlogon.exe 944 Console 1 7,716 K svchost.exe 428 Services 0 12,744 K svchost.exe 796 Services 0 12,240 K svchost.exe 1036 Services 0 22,372 K svchost.exe 1084 Services 0 174,132 K svchost.exe 1112 Services 0 56,144 K svchost.exe 1288 Services 0 18,640 K svchost.exe 1404 Services 0 29,616 K spoolsv.exe 1576 Services 0 25,924 K svchost.exe 1616 Services 0 12,788 K AppleMobileDeviceService. 1728 Services 0 9,796 K avgwdsvc.exe 1820 Services 0 8,268 K mDNSResponder.exe 1844 Services 0 5,832 K w3dbsmgr.exe 1108 Services 0 43,760 K QBCFMonitorService.exe 1336 Services 0 16,408 K svchost.exe 2404 Services 0 28,240 K taskhost.exe 3020 Console 1 12,372 K dwm.exe 2280 Console 1 5,968 K explorer.exe 2964 Console 1 152,476 K WUDFHost.exe 3316 Services 0 6,740 K svchost.exe 3408 Services 0 5,556 K RAVCpl64.exe 3684 Console 1 13,864 K igfxtray.exe 3700 Console 1 7,804 K hkcmd.exe 3772 Console 1 7,868 K igfxpers.exe 3788 Console 1 10,940 K sidebar.exe 3836 Console 1 84,400 K chrome.exe 3964 Console 1 19,640 K pptd40nt.exe 4068 Console 1 5,156 K acrotray.exe 3908 Console 1 14,676 K avgtray.exe 3872 Console 1 9,508 K jusched.exe 4076 Console 1 4,412 K iTunesHelper.exe 1532 Console 1 87,308 K SearchIndexer.exe 3492 Services 0 36,948 K iPodService.exe 4136 Services 0 7,944 K BrccMCtl.exe 4276 Console 1 18,132 K splwow64.exe 4380 Console 1 32,600 K qbupdate.exe 4836 Console 1 24,236 K svchost.exe 4288 Services 0 20,700 K wmpnetwk.exe 3112 Services 0 9,516 K FNPLicensingService.exe 5248 Services 0 5,852 K QBW32.EXE 5508 Console 1 127,068 K QBDBMgrN.exe 5600 Services 0 42,252 K EXCEL.EXE 2512 Console 1 99,100 K LMS.exe 3188 Services 0 5,616 K UNS.exe 1600 Services 0 7,308 K axlbridge.exe 5260 Console 1 5,132 K chrome.exe 5888 Console 1 200,336 K chrome.exe 3536 Console 1 26,076 K chrome.exe 1952 Console 1 20,168 K chrome.exe 4596 Console 1 24,696 K chrome.exe 4292 Console 1 48,096 K chrome.exe 2796 Console 1 23,520 K Acrobat.exe 1240 Console 1 87,252 K 123w.exe 4892 Console 1 22,728 K calc.exe 1700 Console 1 12,636 K chrome.exe 1328 Console 1 28,888 K chrome.exe 3696 Console 1 47,012 K rundll32.exe 6320 Console 1 7,104 K chrome.exe 4928 Console 1 44,248 K AVGIDSAgent.exe 260 Services 0 12,940 K avgfws.exe 6052 Services 0 26,912 K avgnsa.exe 5064 Services 0 2,496 K avgrsa.exe 3088 Services 0 2,200 K avgcsrva.exe 2596 Services 0 380 K avgcsrva.exe 6948 Services 0 408 K StikyNot.exe 452 Console 1 14,772 K chrome.exe 4580 Console 1 28,200 K chrome.exe 4016 Console 1 57,756 K svchost.exe 7140 Services 0 4,500 K chrome.exe 6264 Console 1 56,824 K chrome.exe 7008 Console 1 56,896 K chrome.exe 2224 Console 1 38,032 K taskhost.exe 612 Console 1 7,228 K chrome.exe 6000 Console 1 10,928 K chrome.exe 2568 Console 1 43,052 K chrome.exe 272 Console 1 75,988 K chrome.exe 7328 Console 1 53,240 K PaprPort.exe 7976 Console 1 137,152 K pplinks.exe 7500 Console 1 14,052 K ppscanmg.exe 5744 Console 1 18,996 K taskeng.exe 7388 Console 1 6,308 K SearchProtocolHost.exe 8024 Services 0 8,804 K SearchFilterHost.exe 7232 Services 0 7,848 K chrome.exe 8016 Console 1 37,440 K cmd.exe 7692 Console 1 3,096 K conhost.exe 7516 Console 1 5,872 K tasklist.exe 8160 Console 1 5,772 K WmiPrvSE.exe 7684 Services 0 6,400 K Any help with this would be greatly appreciated, I've been beating my head against a wall over this all day.

• All Xen domU LVM volumes corrupt after reboot

  I'm running a Debian Squeeze dom0, and after rebooting it all 7 of my domUs have data corruption. Each is setup as ext3 partition directly on a separate lvm2 volume. None of the lvm volumes will mount; all have bad superblocks. I've tried e2fsck with each superblock to no avail. What else can I try? Each domU has two LVM volumes connected to it, one for the disk and one for swap. The disk is mounted at root, formatted as a normal ext3 partition as a xen-blk device. The volumes are never mounted outside of the guest OS. I'm running Ubuntu 11.04 using the instructions here. I'm not sure that they didn't shutdown properly, all I know is they were corrupt after I issues a clean 'reboot' on the dom0. Here's a sample Xen config file; the rest are the same except for name, vcpus, memory, vif and disk. name = 'load1' vcpus = 2 memory = 512 vif = ['bridge=prbr0', 'bridge=eth0'] disk = ['phy:/dev/VolGroup00/load1-disk,xvda,w','phy:/dev/VolGroup00/load1-swap,xvdb,w'] #============================================================================ # Debian Installer specific variables def check_bool(name, value): value = str(value).lower() if value in ('t', 'tr', 'tru', 'true'): return True return False global var_check_with_default def var_check_with_default(default, var, val): if val: return val return default xm_vars.var('install', use='Install Debian, default: false', check=check_bool) xm_vars.var("install-method", use='Installation method to use "cdrom" or "network" (default: network)', check=lambda var, val: var_check_with_default('network', var, val)) # install-method == "network" xm_vars.var("install-mirror", use='Debian mirror to install from (default: http://archive.ubuntu.com/ubuntu)', check=lambda var, val: var_check_with_default('http://archive.ubuntu.com/ubuntu', var, val)) xm_vars.var("install-suite", use='Debian suite to install (default: natty)', check=lambda var, val: var_check_with_default('natty', var, val)) # install-method == "cdrom" xm_vars.var("install-media", use='Installation media to use (default: None)', check=lambda var, val: var_check_with_default(None, var, val)) xm_vars.var("install-cdrom-device", use='Installation media to use (default: xvdd)', check=lambda var, val: var_check_with_default('xvdd', var, val)) # Common options xm_vars.var("install-arch", use='Debian mirror to install from (default: amd64)', check=lambda var, val: var_check_with_default('amd64', var, val)) xm_vars.var("install-extra", use='Extra command line options (default: None)', check=lambda var, val: var_check_with_default(None, var, val)) xm_vars.var("install-installer", use='Debian installer to use (default: network uses install-mirror;

• Nginx + PHP-FPM executes script, but returns 404

  - by MorfiusX

  I am using Nginx + PHP-FPM to run a Wordpress based site. I have a URL that should return dynamically generated JSON data for use with the DataTables jQuery plugin. The data is returned properly, but with a return code of 404. I think this is a Nginx config issue, but I haven't been able to figure out why. The script 'getTable.php' works properly on the production version of the site which is currently using Apache. Anyone know how I can get this to work on Nginx?

• CUPS basic auth error through web interface

  - by Inaimathi

  I'm trying to configure CUPS to allow remote administration through the web interface. There's enough documentation out there that I can figure out what to change in my cupsd.conf (changing Listen localhost:631 to Port 631, and adding Allow @LOCAL to the /, /admin and /admin/conf sections). I'm now at the point where I can see the CUPS interface from another machine on the same network. The trouble is, when I try to Add Printer, I'm asked for a username and password, but my response is rejected even when I know I've gotten it right (I assume it's asking for the username and password of someone in the lpadmin group on the server machine; I've sshed in with credentials its rejecting, and the user I'm using has been added to the lpadmin group). If I disable auth outright, by changing DefaultAuthType Basic to DefaultAuthType None, I get an "Unauthorized" error instead of a password request when I try to Add Printer. What am I doing wrong? Is there a way of letting users from the local network to administer the print server through the CUPS web interface? EDIT: By request, my complete cupsd.conf (spoiler: minimally edited default config file that comes with the edition of CUPS from the Debian wheezy repos): LogLevel warn MaxLogSize 0 SystemGroup lpadmin Port 631 # Listen localhost:631 Listen /var/run/cups/cups.sock Browsing On BrowseOrder allow,deny BrowseAllow all BrowseLocalProtocols CUPS dnssd # DefaultAuthType Basic DefaultAuthType None WebInterface Yes <Location /> Order allow,deny Allow @LOCAL </Location> <Location /admin> Order allow,deny Allow @LOCAL </Location> <Location /admin/conf> AuthType Default Require user @SYSTEM Order allow,deny Allow @LOCAL </Location> # Set the default printer/job policies... <Policy default> # Job/subscription privacy...

• MySQL 5.1.49 freezing every two days

  - by maximus

  Hi all, our mysql system is "freezing" every two days. By "freezing" i mean the following: it doesn't respond to ping we can't login with SSH we don't get any answer from MySQL there is no entry in the error logs! neither from linux neither from MySQL. we have already changed to a completely new hardware, we have the same problem, so it's definitely not a hardware problem. we do not have any other software installed except a firewall (iptables rule) we can restart the server from another server using rsyslog (www.rsyslog.com)(software reset) Could someone help me, by giving me some pointers what could i do to figure out the problem? I have included every detail about our settings. Thank you in advance for your help. Max. Our system parameters and settings: System-Memory: 12GB Processor: Intel 7-920 Quadcore Operating system: Debian 5 (lenny) 64bit MySQL 5.1.49 Databases: (a) a small phpbb forum (b) a 6GB database 3 tables with about 15 million rows my.cnf # # The MySQL database server configuration file. # # You can copy this to one of: # - "/etc/mysql/my.cnf" to set global options, # - "~/.my.cnf" to set user-specific options. # # One can use all long options that the program supports. # Run program with --help to get a list of available options and with # --print-defaults to see which it would actually understand and use. # # For explanations see # http://dev.mysql.com/doc/mysql/en/server-system-variables.html # This will be passed to all mysql clients # It has been reported that passwords should be enclosed with ticks/quotes # escpecially if they contain "#" chars... # Remember to edit /etc/mysql/debian.cnf when changing the socket location.

• Confirm disk is broken when it passes all diagnostics

  - by Halfgaar

  I have a system with a potentially broken disk, but the disk passes all manner of diagnostics. I have been unable to confirm that the disk is broken. What are my options? I could just replace the disk, but because this situation is very similar to another more severe situation I have (long story), I'd like to actually make a proper diagnosis as opposed to randomly binning hardware. The issue and history is this: I had a Debian Linux PC (500 MHz P3) acting as router, nagios and munin. It crashed every couple of weeks. No logs or dmesg could be obtained (because it's an old Compaq that only boots when you configure it as keyboardless, making connecting a keyboard later, once it's booted, impossible). At the time, I just replaced the computer with another Compaq (P4 2.4 GHz) because I thought the hardware was faulty. However, it still crashed every couple of weeks. the difference is that on this computer, I can still SSH into it. It gives all kinds of errors on hda. I'd like to confirm that the disk is broken, but nothing I do confirms this: SMART error logs shows no errors. Normally when a disk starts acting up, SMART my pass, but it still records a read-error in the error log. SMART self-test (smartctl -t long /dev/sda) completes without errors. re-allocated sector count (a tell-tale parameter) has been 31 all its life, even when the disk was still in use in my desktop PC years ago, and it still is. The figure never changed. dd if=/dev/sda of=/dev/null bs=4096 passes with flying colors. What else can I do to assess the health of the drive? Again, this is not about making this router fully functional again, this is a disk forensic question, because it just so happens that I have another server that potentially has the same problem, and knowing the answer to this will possibly help me greatly. For the record, below are logs and such. This is the smartctl -a output: smartctl 5.40 2010-07-12 r3124 [i686-pc-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Model Family: Seagate Barracuda 7200.7 and 7200.7 Plus family Device Model: ST3120026A Serial Number: 5JT1CLQM Firmware Version: 3.06 User Capacity: 120,034,123,776 bytes Device is: In smartctl database [for details use: -P show] ATA Version is: 6 ATA Standard is: ATA/ATAPI-6 T13 1410D revision 2 Local Time is: Mon Jul 1 21:18:33 2013 CEST SMART support is: Available - device has SMART capability.

• Proper network configuration for a KVM guest to be on the same networks at the host

  - by Steve Madsen

  I am running a Debian Linux server on Lenny. Within it, I am running another Lenny instance using KVM. Both servers are externally available, with public IPs, as well as a second interface with private IPs for the LAN. Everything works fine, except the VM sees all network traffic as originating from the host server. I suspect this might have something to do with the iptables-based firewall I'm running on the host. What I'd like to figure out is: how to I properly configure the host's networking such that all of these requirements are met? Both host and VMs have 2 network interfaces (public and private). Both host and VMs can be independently firewalled. Ideally, VM traffic does not have to traverse the host firewall. VMs see real remote IP addresses, not the host's. Currently, the host's network interfaces are configured as bridges. eth0 and eth1 do not have IP addresses assigned to them, but br0 and br1 do. /etc/network/interfaces on the host: # The primary network interface auto br1 iface br1 inet static address 24.123.138.34 netmask 255.255.255.248 network 24.123.138.32 broadcast 24.123.138.39 gateway 24.123.138.33 bridge_ports eth1 bridge_stp off auto br1:0 iface br1:0 inet static address 24.123.138.36 netmask 255.255.255.248 network 24.123.138.32 broadcast 24.123.138.39 # Internal network auto br0 iface br0 inet static address 192.168.1.1 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 bridge_ports eth0 bridge_stp off This is the libvirt/qemu configuration file for the VM: <domain type='kvm'> <name>apps</name> <uuid>636b6620-0949-bc88-3197-37153b88772e</uuid> <memory>393216</memory> <currentMemory>393216</currentMemory> <vcpu>1</vcpu> <os> <type arch='i686' machine='pc'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='cdrom'> <target dev='hdc' bus='ide'/> <readonly/> </disk> <disk type='file' device='disk'> <source file='/raid/kvm-images/apps.qcow2'/> <target dev='vda' bus='virtio'/> </disk> <interface type='bridge'> <mac address='54:52:00:27:5e:02'/> <source bridge='br0'/> <model type='virtio'/> </interface> <interface type='bridge'> <mac address='54:52:00:40:cc:7f'/> <source bridge='br1'/> <model type='virtio'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target port='0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> </devices> </domain> Along with the rest of my firewall rules, the firewalling script includes this command to pass packets destined for a KVM guest: # Allow bridged packets to pass (for KVM guests). iptables -A FORWARD -m physdev --physdev-is-bridged -j ACCEPT (Not applicable to this question, but a side-effect of my bridging configuration appears to be that I can't ever shut down cleanly. The kernel eventually tells me "unregister_netdevice: waiting for br1 to become free" and I have to hard reset the system. Maybe a sign I've done something dumb?)

• Can't log in via SSH to any accounts set to use /bin/bash as a default shell

  - by Gui Ambros

  I'm trying to install bash as the default shell on a ARM Linux running on an embedded device (Synology DS212+ NAS). But there's something really wrong, and I can't figure out what it is. Symptoms: 1) Root has /bin/bash as default shell, and can log in normally via SSH: $ grep root /etc/passwd root:x:0:0:root:/root:/bin/bash $ ssh root@NAS root@NAS's password: Last login: Sun Dec 16 14:06:56 2012 from desktop # 2) joeuser has /bin/bash as default shell, and receives "Permission denied" when trying to log in via SSH: $ grep joeuser /etc/passwd joeuser:x:1029:100:Joe User:/home/joeuser:/bin/bash $ ssh joeuser@localhost joeuser@NAS's password: Last login: Sun Dec 16 14:07:22 2012 from desktop Permission denied, please try again. Connection to localhost closed. 3) changing joeuser's shell back to /bin/sh: $ grep joeuser /etc/passwd joeuser:x:1029:100:Joe User:/home/joeuser:/bin/sh $ ssh joeuser@localhost Last login: Sun Dec 16 15:50:52 2012 from localhost $ To make things even more strange, I can log in as joeuser using /bin/bash using the serial console (!). Also a su - joeuser as root works fine, so the bash binary itself is working fine. In an act of despair, I changed joeuser's uid to 0 on /etc/passwd, but also didn't work, so it doesn't seem to be anything permission related. Seems that bash is doing some extra checking that sshd didn't like, and blocking the connections for non-root users. Maybe some sort of sanity checking - or terminal emulation - that is triggering the SIGCHLD, but only when called via ssh. I already went through every single item on sshd_config, and also put SSHD in debug mode, but didn't find anything strange. Here's my /etc/ssh/sshd_config: LogLevel DEBUG LoginGraceTime 2m PermitRootLogin yes RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile %h/.ssh/authorized_keys ChallengeResponseAuthentication no UsePAM yes AllowTcpForwarding no ChrootDirectory none Subsystem sftp internal-sftp -f DAEMON -u 000 And here's the output from /usr/syno/sbin/sshd -d, showing the failed attempt of joeuser trying to log in, with /bin/bash as the shell: debug1: Config token is loglevel debug1: Config token is logingracetime debug1: Config token is permitrootlogin debug1: Config token is rsaauthentication debug1: Config token is pubkeyauthentication debug1: Config token is authorizedkeysfile debug1: Config token is challengeresponseauthentication debug1: Config token is usepam debug1: Config token is allowtcpforwarding debug1: Config token is chrootdirectory debug1: Config token is subsystem debug1: HPN Buffer Size: 87380 debug1: sshd version OpenSSH_5.8p1-hpn13v11 debug1: read PEM private key done: type RSA debug1: private host key: #0 type 1 RSA debug1: read PEM private key done: type DSA debug1: private host key: #1 type 2 DSA debug1: read PEM private key done: type ECDSA debug1: private host key: #2 type 3 ECDSA debug1: rexec_argv[0]='/usr/syno/sbin/sshd' debug1: rexec_argv[1]='-d' Set /proc/self/oom_adj from 0 to -17 debug1: Bind to port 22 on ::. debug1: Server TCP RWIN socket size: 87380 debug1: HPN Buffer Size: 87380 Server listening on :: port 22. debug1: Bind to port 22 on 0.0.0.0. debug1: Server TCP RWIN socket size: 87380 debug1: HPN Buffer Size: 87380 Server listening on 0.0.0.0 port 22. debug1: Server will not fork when running in debugging mode. debug1: rexec start in 6 out 6 newsock 6 pipe -1 sock 9 debug1: inetd sockets after dupping: 4, 4 Connection from 127.0.0.1 port 52212 debug1: HPN Disabled: 0, HPN Buffer Size: 87380 debug1: Client protocol version 2.0;

I also tried using a pre-compiled binary from the Optware distribution, but had the exact same problem. I checked for missing shared libraries using objdump -x, but they're all there. Any ideas what could be causing this "Permission denied, please try again."? I'm almost diving in the bash source code to investigate, but trying to avoid hours chasing something that may be silly.

• Weird routing issue (updated)

  - by smccloud

  I just updated the route tables due to a mistake on my part. I am working on getting networking working correctly on a cluster of 14 virtual servers at a customer site. 11 of them work fine for routing and 3 don't work correctly for their administrative network (172.28.56.0). All are running Windows Web Server 2008R2. Default gateway is set on the production network (172.28.58.0) and not on the administrative network (handled with persistent static routes). On a working server, route print gives me the following (MACs redacted) =========================================================================== Interface List 11...XX XX XX XX XX XX ......Intel(R)

• Can't deploy rails 4 app on Bluehost with Passenger 4 and nginx

  - by user2205763

  I am at Bluehost (dedicated server) trying to run a rails 4 app. I asked to have my server re-imaged, specifying that I do not want rails, ruby, or passenger install automatically as I wanted to install the latest versions myself using a version manager (Bluehost by default offers rails 2.3, ruby 1.8, and passenger 3, which won't work with my app). I installed ruby 1.9.3p327, rails 4.0.0, and passenger 4.0.5. I can verify this by typing, "ruby -v", "rails -v", and "passenger -v" (also "gem -v"). I made sure to install these not as root, so that I don't get a 403 forbidden error when trying to deploy the app. I installed passenger by typing "gem install passenger", and then installed the nginx passenger module (into "/nginx") with "passenger-install-nginx-module". I am trying to run my rails app on a subdomain, http://development.thegraduate.hk (I am using the subdomain to show my client progress on the website). In bluehost I created that subdomain, and had it point to "public_html/thegraduate". I then created a symlink from "rails_apps/thegraduate/public" to "public_html/thegraduate" and verified that the symlink exists. The problem is: when I go to http://development.thegraduate.hk, I get a directory listing. There is nothing resembling a rails app. I have not added a .htaccess file to /rails_apps/thegraduate/public, as that was never specified in the installation of passenger. It was meant to be 'install and go'. When I type "passenger-memory-status", I get 3 things: - Apache processes (7) - Nginx processes (0) - Passenger processes (0) So it appears that nginx and passenger are not running, and I can't figure out how to get it to run (I'm not looking to have it run as a standalone server). Here is my nginx.conf file (/nginx/conf/nginx.conf): #user nobody; worker_processes 1; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { passenger_root /home/thegrad4/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/passenger-4.0.5; passenger_ruby /home/thegrad4/.rbenv/versions/1.9.3-p327/bin/ruby; include mime.types; default_type application/octet-stream; #log_format main '$remote_addr - $remote_user [$time_local] "$request" ' # '$status $body_bytes_sent "$http_referer" ' # '"$http_user_agent" "$http_x_forwarded_for"'; #access_log logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; server { listen 80; server_name development.thegraduate.hk; root ~/rails_apps/thegraduate/public; passenger_enabled on; #charset koi8-r; #access_log logs/host.access.log main; location / { root html; index index.html index.htm; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # #location ~ \.php$ { # root html; # fastcgi_pass 127.0.0.1:9000; # fastcgi_index index.php; # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; # include fastcgi_params; #} # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /\.ht { # deny all; #} } # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443; # server_name localhost; # ssl on; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_timeout 5m; # ssl_protocols SSLv2 SSLv3 TLSv1; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} } I don't get any errors, just the directory listing. I've tried to be as detailed as possible. Any help on this issue would be greatly appreciated as I've been stumped for the past 3 days. Scouring the web has not helped as my issue seems to be specific to me. Thanks so much. If there are any potential details I forgot to specify, just ask. ** ADDITIONAL INFORMATION ** Going to development.thegraduate.hk/public/ will correctly display the index.html page in /rails_apps/thegraduate/public. However, changing root in the routes.rb file to "root = 'home#index'" does nothing.

• Can someone explain the "use-cases" for the default munin graphs?

  - by exhuma

  When installing munin, it activates a default set of plugins (at least on ubuntu). Alternatively, you can simply run munin-node-configure to figure out which plugins are supported on your system. Most of these plugins plot straight-forward data. My question is not to explain the nature of the data (well... maybe for some) but what is it that you look for in these graphs? It is easy to install munin and see fancy graphs. But having the graphs and not being able to "read" them renders them totally useless. I am going to list standard plugins which are enabled by default on my system. So it's going to be a long list. For completeness, I am also going to list plugins which I think to understand and give a short explanation as to what I think it's used for. Pleas correct if I am wrong with any of them. So let me split this questions in three parts: Plugins where I don't even understand the data Plugins where I understand the data but don't know what I should look out for Plugins which I think to understand Plugins where I don't even understand the data These may contain questions that are not necessarily aimed at munin alone. Not understanding the data usually mean a gap in fundamental knowledge on operating systems/hardware.... ;) Feel free to respond with a "giyf" answer. These are plugins where I can only guess what's going on... I hardly want to look at these "guessing"... Disk IOs per device (IOs/second)What's an IO. I know it stands for input/output. But that's as far as it goes. Disk latency per device (Average IO wait)Not a clue what an "IO wait" is... IO Service TimeThis one is a huge mess, and it's near impossible to see something in the graph at all. Plugins where I understand the data but don't know what I should look out for IOStat (blocks/second read/written)I assume, the thing to look out for in here are spikes? Which would mean that the device is in heavy use? Available entropy (bytes)I assume that this is important for random number generation? Why would I graph this? So far the value has always been near constant. VMStat (running/I/O sleep processes)What's the difference between this one and the "processes" graph? Both show running/sleeping processes, whereas the "Processes" graph seems to have more details. Disk throughput per device (bytes/second read/written) What's thedifference between this one and the "IOStat" graph? inode table usageWhat should I look for in this graph? Plugins which I think to understand I'll be guessing some things here... correct me if I am wrong. Disk usage in percent (percent)How much disk space is used/remaining. As this is approaching 100%, you should consider cleaning up or extend the partition. This is extremely important for the root partition. Firewall Throughput (packets/second)The number of packets passing through the firewall. If this is spiking for a longer period of time, it could be a sign of a DOS attack (or we are simply recieving a large file). It can also give you an idea about your firewall performance. If it's levelling out and you need more "power" you should consider load balancing. If it's levelling out and see a correlation with your CPU load, it could also mean that your hardware is not fast enough. Correlations with disk usage could point to excessive LOG targets in you FW config. eth0 errors (packets in/out)Network errors. If this value is increasing, it could be a sign of faulty hardware. eth0 traffic (bits/second in/out)Raw network traffic. This should correlate with Firewall throughput. number of threadsAn ever-increasing value might point to a process not properly closing threads. Investigate! processesBreakdown of active processes (including sleeping). A quick spike in here might point to a fork-bomb. A slowly, but ever-increasing value might point to an application spawning sub-processes but not properly closing them. Investigate using ps faux. process priorityThis shows the distribution of process priorities. Having only high-priority processes is not of much use. Consider de-prioritizing some. cpu usageFairly straight-forward. If this is spiking, you may have an attack going on, or a process is hogging the CPU. Idf it's slowly increasing and approaching max in normal operations, you should consider upgrading your hardware (or load-balancing). file table usageNumber of actively open files. If this is reaching max, you may have a process opening, but not properly releasing files. load averageShows an summarized value for the system load. Should correlate with CPU usage. Increasing values can come from a number of sources. Look for correlations with other graphs. memory usageA graphical representation of you memory. As long as you have a lot of unused+cache+buffers you are fine. swap in/outShows the activity on your swap partition. This should always be 0. If you see activity on this, you should add more memory to your machine!

• Nginx no longer servers uwsgi application behind HAProxy - Looks for static file instead

  - by Ralph

  We implemented our web application using web2py. It consists of several modules offering a REST API at various resources (e.g. /dids, /replicas, ...). The API is used by clients implementing requests.py. My problem is that our web app works fine if it's behind HAProxy and hosted by Apache using mod_wsgi. It also works fine if the clients interact with nginx directly. It doesn't work though when using HAProxy in front of nginx. My guess is that HAProxy somehow modifies the request and thus nginx behaves differently i.e. looking for a static file instead of calling the WSGI container. Unfortunately I can't figure out what's exactly going (wr)on(g). Here are the relevant config sections of these three component's config files. At least I guess they are interesting. If you miss anything, please let me know. 1) haproxy.conf frontend app-lb bind loadbalancer:443 ssl crt /etc/grid-security/hostcertkey.pem default_backend nginx-servers mode http backend nginx-servers balance leastconn option forwardfor server nginx-01 nginx-server-int-01.domain.com:80 check 2) nginx.conf: sendfile off; #tcp_nopush on; keepalive_timeout 65; include /etc/nginx/conf.d/*.conf; server { server_name nginx-server-int-01.domain.com; root /path/to/app/; location / { uwsgi_pass unix:///tmp/app.sock; include uwsgi_params; uwsgi_read_timeout 600; # Requests can run for a serious long time } 3) uwsgi.ini [uwsgi] chdir = /path/to/app/ chmod-socket = 777 no-default-app = True socket = /tmp/app.sock manage-script-name = True mount = /dids=did.py mount = /replicas=replica.py callable = application Now when I let my clients go against nginx-server-int-01.domain.com everything is fine.

But due to what ever reasons ngxin seems to assume that it is a static file to be served which eventually results in the file not found message. I searched the web for multiple hours already, but without much luck so far. Any help is very much appreciated. Cheers, Ralph

• Software: Launching League of Legends spectator mode from Command Line (Mac)

  - by Alex Popov

  Background: tl;dr at the end League of Legends has a spectator mode, in which you can watch someone else's game (essentially a replay) with a 3 minute delay. Popular LoL website OP.GG has figured out a clever way of hosting these spectator games on their own servers, thereby making them replayable, as opposed to only being available while the game is on (as Riot does it). If you request a replay from OP.GG, it sends a batch file which looks for where the League is situated and then the magic happens: @start "" "League of Legends.exe" "8394" "LoLLauncher.exe" "" "spectator fspectate.op.gg:4081 tjJbtRLQ/HMV7HuAxWV0XsXoRB4OmFBr 1391881421 NA1" This works fine on Windows. I'm trying to get it to work on Mac (which has an official client). First I tried running the same command by hand, (split for convenience) /Applications/ ... /LeagueOfLegends.app/ ... /LeagueofLegends 8393 LoLLauncher \ /Applications/ ... /LolClient spectator fspectate.op.gg:4081 tjJbtRLQ/HMV7HuAxWV0XsXoRB4OmFBr 1391881421 NA1 Running this, however, just starts the LoLLauncher, which closes all the active League processes. The exactly same thing happens if I just call /Applications/ ... /LeagueOfLegends.app/ ... /LeagueofLegends Next I tried seeing what actually happens when Spectator mode is initiated so I ran $ ps -axf | grep -i lol which showed UID PID PPID C STIME TTY TIME CMD 503 3085 1 0 Wed02pm ?? 0:00.00 (LolClient) 503 24607 1 0 9:19am ?? 0:00.98 /Applications/League of Legends.app/Contents/LOL/RADS/system/UserKernel.app/Contents/MacOS/UserKernel updateandrun lol_launcher LoLLauncher.app 503 24610 24607 0 9:19am ?? 1:08.76 /Applications/League of Legends.app/Contents/LoL/RADS/projects/lol_launcher/releases/0.0.0.122/deploy/LoLLauncher.app/Contents/MacOS/LoLLauncher 503 24611 24610 0 9:19am ?? 1:23.02 /Applications/League of Legends.app/Contents/LoL/RADS/projects/lol_air_client/releases/0.0.0.127/deploy/bin/LolClient -runtime .\ -nodebug META-INF\AIR\application.xml .\ -- 8393 503 24927 24610 0 9:44am ?? 0:03.37 /Applications/League of Legends.app/Contents/LoL/RADS/solutions/lol_game_client_sln/releases/0.0.0.117/deploy/LeagueOfLegends.app/Contents/MacOS/LeagueofLegends 8394 LoLLauncher /Applications/League of Legends.app/Contents/LoL/RADS/projects/lol_air_client/releases/0.0.0.127/deploy/bin/LolClient spectator 216.133.234.17:8088 Yn1oMX/n3LpXNebibzUa1i3Z+s2HV0ul 1400781241 NA1 Of Interest: there is (LolClient) which I cannot kill by it's PID. UserKernel updateandrun lol_launcher LoLLauncher.app is launched first. LoLLauncher is launched by the UserKernel (as we can see from the PPID) The very long command (PID: 24927) is how Spectator mode is launched, and is also launched by UserKernel. Spectator mode is launched in exactly the same way that the OP.GG .bat wanted to, with the only difference that Spectator mode connects to Riot instead of OP.GG's spectate server. I tried attaching GDB to the LolClient, but I couldn't get anything meaningful from it since it's an Adobe AIR application (and I've never used GDB with code other than mine own). Next I ran dtruss -a -b 100m -f -p $PID on everything I could think of: the LolClient, the LolLauncher and the UserKernel and skimmed the half a million lines produced. I found stuff like the GET request used to get the information of the game to spectate, but I could not see any launch of the equivalent of League of Legends.exe with spectator options. Finally, I ran lsof | grep -i lol to see if anything else was opened in the process, but didn't find anything that seemed appropriate. Open were UserKernel, LolLauncher, LolClient, Adobe AIR, LeagueofLegends and then Bugsplat, all of which are expected. None of this seemed especially relevant to figuring out how LeagueofLegends was opened into spectator mode. It obviously can be done, since Spectator mode is accessible from within the client. It seems likely that it can be done from the CLI, since Windows can do it and the clients are supposed to equals. Unless I'm missing something in the difference between how UNIX and Windows handle CLI application launches. My question is if there are any other things I can try to figure out how to launch Spectator mode myself. tl;dr: Trying to get into spectator mode from the CLI. It's possible on Windows (see first code block) but it just restarts League on Mac. What else can I try to find what call is made, and how to reproduce it? PS: Please let me know how I can improve this question or its formatting, I'd love to use StackOverflow/SuperUser, but as the guys said on the podcast this week (Ep. 59) it's very intimidating. Sorry for posting this on StackOverflow the first time :(
