• Configure Nginx to render static files and rewrite file extension or proxy_pass

• Methods to transfer files from Windows server to linux server

  - by Raze2dust

  Hi, I need to transfer webserver-log-like-files containing periodically from windows production servers in the US to linux servers here in India. The files are ~4 MB in size each and I get about 1 file per minute. I can take about 5 mins lag between the files getting written in windows and them being available in the linux machines. I am a bit confused between the various options here as I am quite inexperienced in such design: I am thinking of writing a service in C#.NET which will periodically archive, compress and send them over to the linux machines. These files are pretty compressible. WinRAR can convert 32 MB of these files into a 1.2 MB archive. So that should solve the network transfer speed issue. But then how exactly do I transfer files to linux? I could mount linux drive on windows server using samba, or should I create an ftp server, or send the file serialized as a POST request. Which one would be good? Also, I have to minimize the load on the windows server. Mount the windows drive on linux instead. I could use the mount command or I could use samba here (What are the pros and cons of these two?). I can then write the compressing and copying part in linux itself. I don't trust the internet connection to be very stable, so there should be a good retry mechanism and failure protection too. What are the potential gotchas in these situations, and other points that I must be worried about? Thanks, Hari

• Samba share will not connect (was working yesterday)

  - by David Gard

  I have a CentOS websver with a Samba share set up (\\webserver\websites). I was connected to this share just yesterday without issue, but today my Windows 8 PC will not connect to it. I've also tried making a connection from Windows 7 and Windows XP, all without success. I initially tried restarting my computer, but that did not work. I then tried restarting the Samba service on the webserver (service smb restart), and when that failed I restarted the webserver. All of that was to no avail, and I still cannot connect to the share. The webserver is contactable from my PC (and the others I tried), as the websites it hosts work fine and I'm able to Putty to the server. When connected to the webserver, I can see that Samba is running by using service smb status - service smb status smbd (pid 4685) is running... nmbd (pid 4688) is running... Can anyone please help me to get this share working? Here is my full Samba config (/etc/samba/smb.conf) - [global] workgroup = MYGROUP server string = Samba Server %v log file = /var/log/samba/log.%m max log size = 50 security = user encrypt passwords = yes socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 local master = no [websites] comment = Websites browseable = yes writable = yes path=/var/www/html/ valid users = dgard

• What Windows service binds a NIC to the network?

  - by Bigbio2002

  I have a server that takes several minutes for the NIC to bind itself to the network upon startup (it has a statically-configured IP). This causes DNS/WINS/Intersite Messaging to fail to start, since they're dependent on a network connection. While I'm still attempting to find a root cause to this issue (I've done firmware updates, checked for any odd drivers/services, no luck so far), but in the meantime, I want to adjust the load order of services to ensure that the NIC binds first before these services attempt to start. The only question is, which service is it? The server is running Server 2008 R2 and only has one NIC installed. (On a side note, there are two other small but odd problems occuring with the server. The server had the issue described in KB2298620, which I've fixed. The other problem occurs in Windows Server Backup. No events appear in the upper portion of the window, despite the fact that backups are running in the background. Whenever I attempt to modify the backup schedule, it gives me the error "Not enough storage is available to process this command" and appears to fail, when, in fact, it actually succeeds. These may be separate issues, but something tells me that some of these might share a common root cause.)

• Postgres pgpass windows - not working

  - by Scott

  DB: Postgres 9.0 Client: Windows 7 Server Windows 2008, 64bit I'm trying to connect remotely to a postgres instance for purposes of performing a pg_dump to my local machine. Everything works from my client machine, except that I need to provide a password at the password prompt, and I'd ultimately like to batch this with a script. I've followed the instructions here: http://www.postgresql.org/docs/current/static/libpq-pgpass.html but it's not working. To recap, I've created a file on the client (and tried the server as well): C:/Users/postgres/AppData/postgresql/pgpass.conf, where postgresql is the db user. The file has one line with the following data: *:5432:*postgres:[mypassword] (also tried explicit ip/dbname values, all asterisks, and every combination in between. (I've also tried replacing each '*' with [localhost|myip] and [mydatabasename] respectively. From my client machine, I connect using: pg_dump -h [myip] -U postgres -w [mydbname] [mylocaldumpfile] I'm presuming that I need to provide the '-w' switch in order to ignore password prompt, at which point it should look in the AppData directory on the server. It just comes back with "connection to database failed: fe_sendauth: no password supplied. Any insights are appreciated. As a hack workaround, if there was a way I could tell the windows batch file on my client machine to inject the password at the postgres prompt, that would work as well. Thanks.

• Ubuntu in failed state after upgrade from 10.04 to 10.10 - How to recover?

  - by Harvey

  I was running Ubuntu 10.04 and attempted to upgrade to 10.10. I have a really slow connection (DSL 128kbits/sec) and copying the upgrade files took about 26 hours. I of course let it run unattended. When I came back, I notice the following 3 dlgs: 1. Could not install the upgrades The upgrade has aborted. Your system could be in an unusable state. A recovery will run now (dpkg -- configure -a). 2. gpk-update-icon Distribution upgrades available maverick 10.10 (stable) [more information] [Do no show this again] [Cancel] [Ok] 3. gpk-update-icon Security updates available The following important updates are available for your computer: libwebkit-1.0-2-dbg - Web content engine library for Gtk+ - Debugging symbols libcupsimage2 - Common UNIX Printing System(tm) - Raster image library ... What is the best response to all of this? I went through something similar in an attempted network upgrade from 8.04 to 10.04 and had to reload the unbootable machine fresh from distribution media (all data was lost). I'd like to avoid that here. I have not yet responded to the dialogs, and want to make sure the system is still bootable and not lose my data this time.

• Configuring IE to resolve DNS at the proxy rather than locally.

  - by dankilman

  With the intention of tunneling web traffic through an SSH connection, the following has been done: I've manually configured a PAC file in IE7 in the LAN Settings dialog. I've verified that traffic is routed through my SSH tunnel that is setup for SOCKS5 dynamic port forwarding. I see that IE7 is always trying to resolve the name locally first. What I'm looking for is the ability to have the DNS name resolved at the proxy, rather than locally by the browser. There's a setting in Firefox that specifies DNS remote resolution, and Safari does it automatically. I've verified correct operation for these 2 other browsers. It would be nice if I could get IE to work also. This is for reference so you could understand where does the question originate from. Notice: The question was actually found by the help of google but with no answers available. Considering how it is exactly my question I figured I should just copy/paste over here because I don't think I could describe any better (there is a small introduction though).

• Installing XP through USB-flash disc

  - by Crazy Buddy

  I don't know whether this could be asked here... So, Pardon me for this. Probably, this is based on My laptop and a contradiction to this question asked already here... I tried to format my "government-provided" laptop (No CD-drive). I thought those IT guys are proving that they're too smart..! I have the Windows XP CD right now. I didn't like to stick with some home-made OS from our Government. So, I used another laptop to format the govt. thing and tried to install XP (As I didn't have enough bills to invest on Windows 7 or 8). Case 1: First, I allowed WinSetupFromUSB 1.0 beta 8 to deal with the flash disk. I wondered for the first time that XP text-screen appeared. Using the first part, I formatted my laptop. It started to copy files, entered into the next part, and completed the installation. I started my PC for the first time. XP splash screen appeared. Suddenly, a blue screen flashed and disappeared (I can't even read what it says). Rebooted and arrived at the screen, "Start Windows Normally". It happens and happens still - like an infinite loop :-) Case 2: Next, I used Rufus 1.2.0 to transfer files to my Flash and it screwed everything out. Even if I used Flash to boot, it arrives to the same screen "Start Windows normally". It doesn't show any response of Flash being inserted. Then I recognized that, It's simply copies everything to the flash disk. Case 3: Then, I started with Novicorp WinToFlash (giving utmost priority to this site). I booted with the disk. I entered into the first part - "Text mode". Some lines started running like that "Press F6 if you..." like that. The last thing I saw was, "Setup is starting Windows..." Suddenly a blue screen appeared like this captured one. I've a suspicion that the same screen appears again & again in first case. Man, I'm dead. Case 4: For the sake of my last hope, I used WinSetupFromUSB 0.1.1. I was shocked on arriving at a screen which says something "GRUB4DOS" like that and some commands like {command line, reboot, halt, \find menu.lst} and when I go inside those "find" options, I see "Error:15 - File not found". Googling provided some commands to mount SETUPLDR.BIN file in the "grub" thing which also proved unsuccessful... Some sites say that Factory reset uses only some function keys. A guy said that it's F11 for lenovo. Screw him. It's all a waste-of-time. But, I think SE would help me out. Is our government IT guys doin' this to me? Are they Soooo smart to spark some blue screen in front of me to freak me out? Any suggestions or new (useful) USB transferring things would be appreciated. It's very urgent. So, It'd be better if you guys pay some attention in debugging and help me out..? Thanks for your time guys :-)

• Cisco IOS ACL: Don't permit incoming connections just because they are from port 80

  - by cjavapro

  I am going much based on my memory and I may not be correct on all of this. On a Cisco 851 (IOS) that uses a BVI or a bridge-route (the servers on the inside are configured with static and public IP addresses). I would apply two access lists (both end with deny ip any any log) on FastEthernet4 (the WAN port). There would be one for FA4 in and another for FA4 out. FA4 out would have a line like access-list 110 permit 98.76.54.0 0.0.0.255 gt 1023 any eq http I think this means from 98.76.54.* with a from port of at least 1024 can connect to any other machine with a destination port 80. So, then I have to allow the response to the HTTP connection. FA4 in would have a line like access-list 120 permit any eq http 98.76.54.0 0.0.0.255 gt 1023 Now the problem with that is that anybody on the outside can set their from port to port 80 and then connect to any inside port that is at least 1024. How do we prevent this and require the incoming data to be a response to the outgoing data.

• trying to route between two openvpn clients

  - by user42055

  I have two openvpn clients on the 10.0.1.0 (client1) and 192.168.0.0 (client2) subnets with the server's openvpn connection having the ip 192.168.150.1 The server has ip forwarding enabled. Currently, client1's vpn ip is 192.168.150.10 and the P-t-P ip is 192.168.150.9 I have created the following static route on client1: route add -net 10.0.1.0 netmask 255.255.255.0 gw 192.168.150.9 The routing table on client1 looks like this: Destination Gateway Genmask Flags MSS Window irtt Iface 192.168.150.9 0.0.0.0 255.255.255.255 UH 0 0 0 tun0 192.168.150.1 192.168.150.9 255.255.255.255 UGH 0 0 0 tun0 10.0.1.0 192.168.150.9 255.255.255.0 UG 0 0 0 tun0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 I thought this would be correct to allow traffic from client1 to reach computers on client2's network, but it does not work. Is 192.168.150.9 (the P-t-P address) the correct one to be routing through ? I tried using 192.168.150.1 but I couldn't create the route. I hope this is clear.

• Transfering Files to server IP and port

  - by Mason

  I need to transfer files from my local computer on windows 7 to a server running linux. I access the server with putty through ssh at a specific IPv4 address and port number. I've attempted using the pscp command from my local computer but was denied access by the server. "Fatal: Network error: Connection refused" c:>pscp test.csv userid@**IPv4_Addres***:Port# /path/destination_file_name. Either the server blocks all pscp attempts from unauthorized users (most likely my laptop included) or I used the command incorrectly. If you have experience using this command, where exactly will the file get transfered to, I'm assuming that the path destination starts at my home directory in the server. Also if you have any other alternative methods of transfering the files let me know. Update 1 I have also tried using WinSCP however I got permission denied for that as well, it looks like the server will not let me upload or save files. Solved I had a complete lapse of memory and forgot about sudo (spent too much time with scripts the last 2 months), so I was able to change the permissions to allow external editing. Thanks for all the help guys!

• Strange mysql problem moving website from Ubuntu server to Mac server

  - by evan

  I'm moving a website (php/mysql) from an Ubuntu server to a OSX 10.6 server. I've set up apache to run php scripts and setup the newest version of mysql on the mac. I just copied all of the php files and dumped/imported all of the mysql databases (including the mysql users database). When I visit the page being served on the Mac the page is able to connect to the database, but not query. Specifically this function mysql_error() is returning this error message NO SUCH FILE OR DIRECTORY The reason it's strange is that I'm able to change the php connection strings for mysql on the Ubuntu server so that it points to the Mac server and the page works correctly (so it seems mysql is correctly set up on the mac and definitely contains all of the users and tables it should). Thinking it was something to do with file permissions on the mac, I've changed all of the files 755 and it hasn't helped. Any ideas? Thanks!! UPDATE: I've found this error which I'm relatively certain is related to this problem in /var/log/apache2/error_log PHP Warning: mysql_query(): A link to the server could not be established

• Extending a home wireless network using two routers running tomato

  - by jalperin

  I have two Asus RT-N16 routers each flashed with Tomato (actually Tomato USB). UPSTAIRS: Router 'A' (located upstairs) is connected to the internet via the WAN port and connected via a LAN port to a 10/100/1000 switch (Switch A). Several desktops are also attached to Switch A. Router A uses IP 192.168.1.1. DOWNSTAIRS: I've just acquired Router 'B' and set it to IP 192.168.1.2. I have a cable running from Switch A downstairs to another switch (Switch B). Tivo, a blu-ray player and a Mac are connected to Switch B. My plan was to connect Router B to Switch B so that I have improved wireless access downstairs. (The wireless signal from Router A gets weak downstairs in a number of locations.) How should I configure Router B so that all devices in the house can see and talk to one another? I know that I need to change DHCP on Router B so that it doesn't cover the same range as DHCP on Router A. Should I be using WDS on the two routers, or is that unnecessary since I already have a wired connection between the two routers? Any other thoughts or suggestions? Thanks! --Jeff

• Windows Server 2008 R2 Virtual Network Setup

  - by jpearl01

  Some background: I'm very much new to networking in general, and virtualization in particular. I'm trying to set up a series of VMs as we are transitioning to a thin client setup. I have been supplied a limited number of static ip addresses. The server is located in an offsite building which houses the network we use to connect to the internet, share folders etc. The setup I've been trying to go for is this: The host OS (Windows Server 2008 R2) is bound to one nic using one of the static ips (say, Nic1 and ip 10.255.6.61). I've set up another external virtual network attached to another physical nic , and a virtual private network attached to no nic. There is one VM running the same os (as the host). This VM is connected to both the external virtual network (and uses another static ip say Nic2 and ip 10.255.6.62) and also to the virtual private network (I gave it a static random ip 192.168.88.1 subnet mask 255.255.255.0). This virtual private network is connected to all the other VMs. I'd like to share the internet connection with all the other VMs on the private virtual network, and so I installed the RRAS role on the server connected to Nic2, and selected the option to share the internet over the vpn. I've run through the RRAS wizard a few times, trying different configurations, but none of them seem to be letting the other vms connect to the 'net. The vms seem to connect to the virtual private network fine, they are assigned an ip address and everything, but no internet, and no rest of the network either. The other problem is in general I connect to the vms with RDP. Will that be possible with a setup like this? i.e. will the vms show up as computers on the network? If not, what are my other options? Thanks! ~josh

• RouterLess, house-wired network using multiple powerline adapters

  - by Cliff Arnell

  related to the 'old days' of one ethernet cable tapped with Ts for each monitor.... my question might be very simple... or not. I have an over-the-air internet provider with a wire dish with a powered transceiver and cat5 cable out of the providers supplied modem. I'm presently connecting the output of the modem into my wireless router which sends the internet signal all over the house. Standard stuff, I believe. My Question. Can I just connect the output of the modem into 1 powerline adapter and tie all my equipment such as computer, printer, laptop, Tivo recorder, etc. into 1-each local powerline adapters located near each devices resulting in a 'house-wired' network and no router? I'm bothered by the idea that my over-the-air provider might be using something in my router to establish and keep my IP connection alive. I did have to configure the router for my IP, a router which, in my proposed scenario, would no longer exist. Thank you for your help.

• Flickering dual screens in Virtual Box Ubuntu 13.10 Guest

  - by alexleonard

  I have Ubuntu 13.10 x64 installed as a guest in VirtualBox (under a Windows 8.1 host) and have the settings for the virtual machine setup to run with a monitor count of 2, 128MB video memory and 3D acceleration enabled. In my guest I have the virtual box additions installed (which allowed me to have two 1920x1080 screens). Here's a screenshot of my VM settings. My laptop is an Asus N550JV which has both Intel's HD Graphics 4600 GPU and Nvidia's GeForce GT 750M. By default though I believe the Intel GFX card is being used to render the VM. When I boot up the VM it loads perfectly on dual screens, however whenever I move the mouse from one screen to the other (I have a Dell S2340L running over a HDMI connection as a second screen) the screen flickers. I've tried a variety of settings changes in both Ubuntu and the VM settings, but cannot seem to stop this screen flicker. I also used the NVidia control panel in Windows to force the dedicated graphics card to always be used but found that the display driver sometimes crashed whilst working in the VM, resulting in my VM session being destroyed, so I figured it's better to stick with the Intel GFX as that appears to be more stable. I also tried without 3D acceleration but that was much worse, and if I ran the VM with a low amount of graphics memory it really struggled. Here's my dmesg output: http://pastebin.com/1LJuYWMj (not sure if this is helpful in this situation). I read some posts suggesting changes to /etc/X11/xorg.conf but I don't appear to have an xorg.conf file. There were also a few posts (though related to Synergy) suggesting running xset -dpms but this command doesn't appear to have had any effect for me. As an additional note, I'm finding that window drawing in the guest is a little laggy/glitchy. For example, quickly scrolling through a web page may result in parts of the viewport displaying original content. Certainly I notice drawing issues most in the web browser, but it also impacts other software with parts of the window not being drawn when, say, switching between accounts in thunderbird. Any suggestions greatly appreciated!

• SQL Server 2005 to 2008 DB attach elp please!

  - by Brandon

  I have SQL Server 2005 Standard on my personal machine. I created a very big DB about 21 gb. I made a backup and transferred the .bak file via an ftp program to my dedicated server. I have SQL Server 2008 Enterprise Edition on my dedicated server. I tried restore the transferred .bak file but got an error. I posted the error on here and was told the database is corrupt. How? I don't know. The connection was not interrupted during the ftp transfer. The DB works on my own machine. So then I detached the db on my own machine and transferred the mdf and ldf file to my dedicated server through ftp again and again there were not interruptions. Now I try to attach the db and get this error: The header for file 'DB.mdf' is not a valid database file header. The FILE SIZE property is incorrect. (Microsoft SQL Server, Error: 5172) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&ProdVer=10.00.1442&EvtSrc=MSSQLServer&EvtID=5172&LinkId=20476 I already wasted 21 gb transferring the .bak file. Now I used another 21 to transfer mdf and additional ldf file. Please tell me there's a solution. The db can detach and attach fine on my machine in sql server 2005 but not SQL server 2008 on my server.

• Passwortgeschützter Traffic-meter

  - by UncleBob

  Hallo erstmal, ich habe hier ein kleines Problem für das ich bis jetzt noch keine Lösung habe. Ich lebe in Bosnien und teile hier die Internetverbindung mit der Vermieterin, und wie es in Bosnien so ist haben wir keine Flatrate, sondern eine 15 Giga traffic limite. Das wäre eigentlich mehr als genug, wenn der Sohn der Vermieterin nicht immer überziehen würde, sodass die Rechnungen immer ziemlich teuer ausfallen. Ich habe ihm bereits ein Messprogramm installiert, aber das schaltet er offensichtlich aus sobald er in die Nähe seiner Limite kommt und behauptet dann die Limite nicht überzogen zu haben. Ich brauche also mindestens ein Messprogramm das Passwortgeschützt ist und/oder im Log Zeiten vermerkt wärend denen es nicht eingeschaltet war. Noch besser wäre ein Programm das ihm den Netzzugriff einfach abklemmt wenn er seinen Anteil überschreitet, also eine Mischung aus Trafic-meter und Parental Guard. Kann mir da jemand weiterhelfen? Gtranslated version Hi first, I have a small problem for which I yet have no solution. I live in Bosnia and share the Internet connection here with the owner, and how it is in Bosnia, we do not have a flat rate, but a 15 Giga traffic limite. That would actually would be more than enough, if the son of the landlady does not always cover so that the bills always turn out quite expensive. I have it already installed a monitoring program, but he apparently turns out as soon as he comes close to its limit and then claims not to have the limit excessive. I therefore need at least a measurement program that is password protected and / or in the log notes During low periods where it has not turned on. Even better would be a program that disconnects him from accessing the network if it simply exceeds its share, ie a mixture of Traffic parameters and Parental Guard. Can someone help me there?

• How can I setup OpenVPN with IPv4 and IPv6 using a tap device?

  I've managed to setup OpenVPN for full IPv4 connectivity using tap0. Now I want to do the same for IPv6. Addresses and network setup (note that my real prefix is replaced by 2001:db8): 2001:db8::100:0:0/96 my assigned IPv6 range 2001:db8::100:abc:0/112 OpenVPN IPv6 range 2001:db8::100:abc:1 tap0 (on server) (set as gateway on client) 2001:db8::100:abc:2 tap0 (on client) 2001:db8::1:2:3:4 gateway for server Home laptop (tap0: 2001:db8::100:abc:2/112 gateway 2001:db8::100:abc:1/112) | | | (running Kubuntu 10.10; OpenVPN 2.1.0-3ubuntu1) | wifi | | router | | OpenVPN INTERNET | eth0 | /tap0 VPS (eth0:2001:db8::1:2:3:4/64 gateway 2001:db8::1) (tap0: 2001:db8::100:abc:1/112) (running Debian 6; OpenVPN 2.1.3-2) The server has both native IPv4 and IPv6 connectivity, the client has only IPv4. I can ping6 to and from my server over OpenVPN, but not to other machines (for example, ipv6.google.com). net.ipv6.conf.all.forwarding is set to 1, I've tried disabling net.ipv6.conf.all.accept_ra as well, without luck. Using tcpdump on both the server and client, I can see that packets are actually transferred over tap0 to eth0. The router (2001:db8::1) send a neighbor solicitation for the client (2001:db8::100:abc:2) to eth0 after it receives the ICMP6 echo-request. The server does not respond to that solicitation, which causes the ICMP6 echo-request not be routed to the destination. How can I make this IPv6 connection work?

• central apache log analysis of many hosts

  - by Jason Antman

  We have 30+ apache httpd servers, and are looking to perform analysis on the logs both for historical trending and near "real time" monitoring/alerting. I'm mainly interested in things like error rates (4xx/5xx), response time, overall request rate, etc. but it would also be very useful to pull out more compute-intensive statistics like unique client IPs and user agents per unit of time. I'm leaning towards building this as a centralized collector/server/storage, and am also considering the possibility of storing non-apache logs (i.e. general syslog, firewall logs, etc.) in the same system. Obviously a large part of this will probably have to be custom (at least the connection between pieces and the parsing/analysis we do), but I haven't been able to find much information on people who have done stuff like this, at least at shops smaller than Google/Facebook/etc. who can throw their log data into a hundred-node compute cluster and run Map/Reduce on it. The main things I'm looking for are: - All open source - Some way of collecting logs from apache machines that isn't too resource-intensive, and transports them relatively quickly over the network - Some way of storing them (NoSQL? key-value store?) on the backend, for a given amount of time (and then rolling them up into historical averages) - In the middle of this, a way of graphing in near-real-time (probably also with some statistical analysis on it) and hopefully alerting off of those graphs. Any suggestions/pointers/ideas, to either "products"/projects or descriptions of how other people do this would be greatly helpful. Unfortunately, we're not exactly a new-age-y devops shop, lots of old stuff, homogeneous infrastructure, and strained boxes.

• Can't reliably ping 6224 router from directly-attached system

  - by David Mackintosh

  OK, here's my situation. This is on the internet. The 6224 is the router in this picture and physically resides in Kanata. Both VLAN 1697 and 3994 are provided by an internet service provider. These VLANs are provided through a single 1Gb ethernet wire. The Kanata hosts are directly attached to the 6224; the other two sites are remote. VLAN 3994 is a single IP address space, so theoretically it shouldn't matter physically where the hosts on that subnet are. Here's the problem. I have a monitoring system which is connected further into the internet, so probes from the monitor would come in to this diagram on the 1697 VLAN. When I ping hosts at Albert or Bells Corners from the internet, there is 0 loss. The connection looks perfect. When I ping hosts at Kanata, I lose anywhere from 10 to 40% of the pings. The loss is not predictable, but: when I do lose them, I always lose at least 3, usually 4, rarely more, pings in a bunch. I have attached a monitor directly to the 6224 in Kanata on 3994.. When the monitor pings the 6224 routing interface, I see exactly the same loss pattern -- but NOT at the same time as the loss from the remote system. Ping time is around 1ms. When the monitor pings another system directly attached to the 6224, there is 0 loss. Ping time is about 0.1ms, one-tenth of the time to ping the router. Anyone know what is going on here?

• How to setup a hyper-v domain with internet access

  - by fynnbob

  First off let me say that I'm not a network admin or server guy, I know very little about that stuff. What I'm trying to do is setup a virtualized domain using hyper-V. Here is the configuration: Physical Server: 4Mb RAM Windows Server 2008 R2 running Hyper-V Virtual Environment: One Domain Controller running Windows Server 2008 R2 One Client running Windows Server 2008 R2 I have been successful in setting up a virtual domain controller and adding a virtual client to that domain controller but I'm stuck at trying to give the virtual Environment Internet access. I can give the client VM Internet access if I remove them from the virtual domain but once I add them back to the virtual domain, Internet access is gone. I've read articles describing many different ways this can be done (using RRAS with NAT, using a wireless connection, etc...) but all of those articles only cover a small piece of the setup and also seem to be geared towards people who know there way around networking and servers which I don't. I'd like to know more but my thing is software development and I have my hands full trying to keep up with everything in that realm. I simply want to setup a virtual domain with Internet access for testing. Can anyone point me to any "for Dummy's" type information on how to setup this type of environment or can anyone provide this kind of step-by-step help. Any help would be very much appreciated.

• CloudFront with Custom Origin and ELB

  - by kmfk

  We are using CloudFront for our static assets but also wanted to allow for Gzip. We set up a new distribution with a custom origin pointing back to our application servers which are behind a elastic load balancer. We manually keep the files in sync across the cluster and update them when we publish. However, with this set up, we get nothing but Miss and RefreshHits from CloudFront, which so far has defeated the purpose. Is there any additional settings in order to use an ELB as your custom origin? In the docs, it references this as a viable solution. It appears when we point the distribution to a single server in our production cluster, cloudfront properly caches our assets. Is it possible that the sticky sessions cookie and the subsequent header that gets added by it could be an issue? Cache-Control: no-cache="set-cookie" //Added by load balancer Any ideas? FYI - currently, we have our custom origin pointing to a single EC2 instance, so caching is working correctly - in case you try to curl the file below. Example headers: curl -I http://static.quick-cdn.com/css/9850999.css HTTP/1.0 200 OK Accept-Ranges: bytes Cache-Control: max-age=3700 Cache-Control: no-cache="set-cookie" Content-Length: 23038 Content-Type: text/css Date: Thu, 12 Apr 2012 23:03:52 GMT Last-Modified: Thu, 12 Apr 2012 23:00:14 GMT Server: Apache/2.2.17 (Ubuntu) Vary: Accept-Encoding X-Cache: RefreshHit from cloudfront X-Amz-Cf-Id: K_q7Zy3_jdzlEJ85ukELVtdx1GmuXqApAbZZ7G0fPt0mxRMqPKX5pQ==,RzJmPku-rEIO9WlvuSoKa8hiAaR3dLk5KC4cQMWWrf_MDhmjWe8n6A== Via: 1.0 28c34f9fbf559a21ee16594849e4fc9c.cloudfront.net (CloudFront) Connection: close

• Allowing access to company files accross the internet

  - by Renaud Bompuis

  The premise I've been tasked with finding a solution to the following scenario: our main file server is a Linux machine. on the LAN, users simply access the files using SMB. each user has an account on the file server and his/her own access rights. user accounts are simple passwd/group security accounts, not NIS/LDAP. The problem We want to give users (or at least some of them, say if they belong to a particular group) the ability to access the files from the Internet while travelling. Ideally I'd like a seamless solution. Maybe something that allows the user to access a mapped drive would be ideal. A web-oriented solution is also good but it should present files in a way that is familiar to users, in an explorer-like fashion for instance. Security is a must of course, and users would be expected to log-in. The connection to the server should also be encrypted. Anyone has some pointers to neat solutions? Any experiences? Edit The client machines are Windows only.
