  • DNS Server Behind NAT

    - by Bryan
    I've got a Bind 9 DNS server sitting behind a NAT firewall, assume the Internet facing IP is 1.2.3.4 There are no restrictions on outgoing traffic, and port 53 (TCP/UDP) is forwarded from 1.2.3.4 to the internal DNS server (10.0.0.1). There are no IP Tables rules on either the VPS or the internal Bind 9 server. From a remote Linux VPS located elsewhere on the internet, nslookup works fine # nslookup foo.example.com 1.2.3.4 Server: 1.2.3.4 Address: 1.2.3.4#53 Name: foo.example.com Addresss: 9.9.9.9 However, when using the host command on the remote VPS, I receive the following output: # host foo.example.com 1.2.3.4 ;; reply from unexpected source: 1.2.3.4#13731, expected 1.2.3.4#53 ;; reply from unexpected source: 1.2.3.4#13731, expected 1.2.3.4#53 ;; connection timed out; no servers could be reached. From the VPS, I can establish a connection (using telnet) to 1.2.3.4:53 From the internal DNS server (10.0.0.1), the host command appears to be fine: # host foo.example.com 127.0.0.1 Using domain server: Name: 127.0.0.1 Address: 127.0.0.1#53 Aliases: foo.example.com has address 9.9.9.9 Any suggestions as to why the host command on my VPS is complaining about the reply coming back from another port, and what can I do to fix this?

  • Can't get bonding and bridging to work for KVM

    - by user9546
    Hi everyone. I can't for the life of me get bonding and bridging to work for the KVM setup I'm building. I'm using a fresh install (not an upgrade) of Ubuntu Server 10.10. I have 4 NICs on the same subnet (two intended for each of my two VMs). I'm trying to achieve the setup that Uthark describes here. But following his guidelines didn't work for me. My eth0 and eth1 did not come up, and "brctl show" showed that br0 didn't have any interfaces (the bond). I assumed it didn't work because he's using 10.4, and this article says there's a recent change in bonding: [I can't post more than one hyperlink per post because I'm a newbie.] I had to use this article to get my interfaces to work at all on the same subnet, which is why I have the post-up lines on some of my interfaces: [I can't post more than one hyperlink per post because I'm a newbie.] I installed ifenslave and ethtool. I also created /etc/modprobe.d/aliases.conf with the following content: alias bond0 bonding options bonding mode=6 miimon=100 downdelay=200 updelay=200 And I included "bonding" in /etc/modules So, after several approaches, here is my latest interfaces file: auto lo iface lo inet loopback auto eth5 iface eth5 inet manual auto br5 iface br5 inet static post-up /sbin/ip rule add from [network].79 lookup 10 post-up /sbin/ip route add table 10 default via [network].1 src [network].79 dev br5 address [network].79 netmask 255.255.255.0 network [network].0 broadcast [network].255 gateway [network].1 bridge_ports eth5 bridge_stp off bridge_fd 0 bridge_maxwait 0 auto eth2 iface eth2 inet manual auto br2 iface br2 inet static post-up /sbin/ip rule add from [network].78 lookup 11 post-up /sbin/ip route add table 11 default via [network].1 src [network].78 dev br2 address [network].78 netmask 255.255.255.0 network [network].0 broadcast [network].255 gateway [network].1 bridge_ports eth2 bridge_stp off bridge_fd 0 bridge_maxwait 0 iface eth0 inet manual iface eth1 inet manual auto bond0 iface bond0 inet static bond_miimon 100 bond_mode balance-alb up /sbin/ifenslave bond0 eth0 eth1 down /sbin/ifenslave -d bond0 eth0 eth1 auto br0 iface br0 inet static address [network].60 netmask 255.255.255.0 network [network].0 broadcast [network].255 gateway [network].1 bridge_ports bond0 eth2, eth5, br2, and br5 all seem to be working fine. The only other thing I could find that looked suspicious is an error regarding bonding in /var/log/messages: kernel: [ 3.828684] bonding: Warning: either miimon or arp_interval and arp_ip_target module parameters must be specified, otherwise bonding will not detect link failures! see bonding.txt for details. even though there is a bond-miimon line in /etc/network/interfaces (if that's what they're talking about). Also, the bond seems to go in and out of promiscuous mode several times on boot: Jan 20 14:19:02 kvmhost kernel: [ 3.902378] device bond0 entered promiscuous mode Jan 20 14:19:02 kvmhost kernel: [ 3.902390] device bond0 left promiscuous mode Jan 20 14:19:02 kvmhost kernel: [ 3.902393] device bond0 entered promiscuous mode Jan 20 14:19:02 kvmhost kernel: [ 3.902397] device bond0 left promiscuous mode Jan 20 14:19:03 kvmhost kernel: [ 4.998990] device bond0 entered promiscuous mode Jan 20 14:19:03 kvmhost kernel: [ 4.999005] device bond0 left promiscuous mode Jan 20 14:19:03 kvmhost kernel: [ 4.999008] device bond0 entered promiscuous mode Jan 20 14:19:03 kvmhost kernel: [ 4.999012] device bond0 left promiscuous mode Any advice would be greatly appreciated. It seems that this must be possible, based on other posts, but I can't see what I'm doing wrong. Thanks.

  • Voice Recognition Connection problem

    - by user244190
    I,m trying to work through and test a Voice Recognition example based on the VoiceRecognition.java example at http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/VoiceRecognition.html but when click on the button to create the activity, I get a dialog that says Connection problem. My Manifest file is using the Internet Permission, and I understand it passes the to the Google Servers. Do I need to do anything else to use this. Code below UPDATE 2: Thanks to Steve, I have been able to install the USB Driver and debug the app directly on my Droid.

  • MSTSC Not working, disconnects shortly after connecting

    - by F4r-20
    I'm currently having a problem connecting remotely to a server. It is a brand new build Windows 2008 R2, remote users are enabled. I'm trying to connect from a Windows 7 machine. Everytime I remotely connect to the server it will stay connected for a matter of seconds (maybe 3-5) and then disconnect and I get the standard old cannot connect and list of reasons it could be. Then I cannot connect again and get this prompt until I restart the server. As soon as it's finished restarting, it happens all over again. The network and hardware configuration between the two machines is completely reliable. Does anybody know what else I could try? Thanks.

  • I can't set the resolution to that recommended by my monitor

    - by F4r-20
    Firstly, I have looked here but didn't find what I needed. I have a Dell Optiplex 380 only using the on-board graphics (believe its the Intel G41 Express Chipset) but I can't seem to get the resolution right. The monitor I'm using (HP LE1901w) wants me to use 1440x900 but the only options I get are: 1600 x 1200 1366 x 768 1360 x 768 1280 x 1024 1280 x 960 1152 x 864 1024 x 768 800 x 600 So it will allow me to go higher or lower but not 1440x900. I've tried getting the driver from various different sources (Dell, Intel, Windows 7 Update) but still can't get that option. Does anybody know what else I can try?

  • I can't connect to my WAMP server from a client on the same network

    - by F4r-20
    Usually I would manually set up Apache and PHP but this time I thought I would go for the WAMP alternative. I've set up WAMP and it's working perfectly fine on the host machine. If I try and access the WAMP server from another machine on the same network (same subnet too: 192.168.1.*) I get this message: Forbidden You don't have permission to access / on this server. I have been online and gone through steps. I have changed Allow from 127.0.0.1 to Allow from all and it's still not working. Is there anything else I can try? Thanks.

  • Server's network capabilities are going into some sort of sleep mode?

    - by F4r-20
    I'm having trouble with a server (Windows Server 2008 R2) on my network. It is going down for short periods at a time, but not very often. The interesting thing: If I ping the server from my computer (we'll call this client-x) using the -t switch, I will continuously get no reply. However the second I ping client-x from the server, I can see the previous ping pick up a reply? It's almost as if pinging client-x from the server, wakes up the networking capabilities? Has anybody got any idea what is going on here?

  • What are the names of network interfaces on the Motorola CLIQ XT?

    - by RS
    The network interfaces on Android interfaces are listed as directories in the file system in /sys/class/net/. For most Android devices the network interface for gprs traffic is called rmnet0 and for Wi-Fi it's usually eth0 or tiwlan0. I suspect that the cell interface for the Motorola CLIQ XT is rmnet0, but I would like to have this confirmed + know the name of the Wi-Fi interface. Also it would be good to know the device id for this model. This is the value available as android.os.Build.DEVICE in the Java SDK. (E.g. T-Mobile G1 uses dream, Samsung Galaxy uses GT-I7500, and Motorolda Droid uses sholes.)

  • Configuring VirtualBox host only networking: OSX host, Ubuntu guest

    - by Greg K
    I have a Ubuntu guest configured with two interfaces, eth0 is using NAT and works fine, I can access the net. The second interface eth1 is set to host only networking and VirtualBox has created a vboxnet0 virtual adapter on the host. I've configured vboxnet0 in VirtualBox adapter settings with the following: ip 192.168.21.20 subnet 255.255.255.0 Once the VM guest is running, ifconfig on OSX has vboxnet0 setup as: vboxnet0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether 0a:00:27:00:00:00 inet 192.168.21.20 netmask 0xffffff00 broadcast 192.168.21.255 In the guest, eth0 is set to use DHCP, I've statically assigned eth1 to 192.168.21.20 (is this a mistake?): auto eth1 iface eth1 inet static address 192.168.21.20 netmask 255.255.255.0 network 192.168.21.0 broadcast 192.168.21.255 gateway 192.168.21.1 There is no device on 192.168.21.1 - what should I set my gateway to?

  • Unable to execute gs program: No such file or directory

    - by Imran
    I've setup CUPS + Avahi on my NAS box in order to enable AirPrint with my existing network printer. Printing a test page via CUPS and printing us lp works fine, and I am able to see my printer on the printer list on my iOS device. However when sending a print job from my iOS device the printer status is set to paused and doesnt print anything. When checking the error_logs I have found this line which I believe is causing the error.

What I need to do: There are three network interfaces, currently set up as red (WAN), green (LAN, 192.168.20.0/24) and orange (remote network 10.1.20.0/24). The orange interface is a direct fiber link to another organization. Simple description: Traffic and networks appear to be properly configured at this point, but I have many (150+) specific IPs on the LAN which, when accessing the resources on the 10.1.20.x network, need to be mangled to appear to be coming from the 10.1.20.0/24 network (and return traffic properly delivered). The routing on the far side was configured earlier and should be fine, but I need to redirect any packets coming across destined for those IPs to end up at their proper destination. The addressing is fixed and predictable (ie. 192.168.20.125 - 10.1.20.125). I need to insert whatever rules I have into the IPCop ruleset through /etc/rc.local I know, I'm just not sure about how I should structure this. There's CUSTOMOUTPUT and CUSTOMINPUT targets, both which currently just consist of the single rule redirecting packets to the OVPNOUTPUT/OVPNINPUT targets, so I'm guessing I should insert a rule matching outbound packets destined for the 10.1.20.x network and redirecting to a new target (maybe called TO-ORANGE) and a rule at the top of CUSTOMINPUT which redirects to a FROM-ORANGE target. Under those targets, I would have rules which do the IP matching and mangling. Am I approaching this right? If so, I'm not very familiar with mangle, and would appreciate seeing examples of how to write that source-IP rewrite. If not, how would you suggest doing this? TIA! edit: I notice additionally that the nat table has CUSTOMPREROUTING and CUSTOMPOSTROUTING targets, I guess I could alternatively post the rules in there....

  • Need help trouble shooting high CPU usage by PHP-fpm

    - by user432506
    There is a problem that is driving me crazy. After the day I tried to fix the CPU usage problem of my VPS, the CPU load has grown from 60% to 150%, and I have no idea what causes the problem. Please help me. I had installed a copy of mediawiki on a Linode 1024. The wiki is running on Niginx + PHP-fpm + MySql. The wiki doesn't have much traffic, only around 4000 requests/day, mostly from Google and Bing bots. It had been using around 60% (of total 400% on the Linode) of the CPU before. I thought it was a bit high, so two day ago, I was trying to fix the problem (not knowing what was waiting for me). I did nothing but added a new empty line to wiki's configure file, which would change the modified time of the configure file, and then all the cached page files would be set invalidated. I had done that before, and that would cause high CPU usage, but normally it would take only hours to let things back to normal again. Not this time, my CPU usage has been around 150% for more than two days. It is php-fpm using most of CPU reassures. Using 100% of three cores is not rare. I hadn't seen that before. There are other sites on the Linode, but it should be the wiki. Because if I offline the wiki, CPU usage will drop back to around 40% soon. The day I also duplicated php-fpm.conf, and opened it, but didn't changed it. I have no idea what I did wrong. I here ask for help to save myself from being crazy!!! It is php-fpm. Is there a way to find out what is it doing? I mean like which scripts are related and what function codes are running? top: top - 06:34:33 up 10 days, 4:23, 2 users, load average: 1.10, 1.24, 1.37 Tasks: 76 total, 4 running, 72 sleeping, 0 stopped, 0 zombie Cpu(s): 61.1%us, 3.1%sy, 0.0%ni, 32.8%id, 2.9%wa, 0.0%hi, 0.0%si, 0.1%st Mem: 1028684k total, 945192k used, 83492k free, 89580k buffers Swap: 524284k total, 18084k used, 506200k free, 530380k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 26721 www-data 20 0 208m 54m 34m R 99 5.4 0:09.07 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26592 www-data 20 0 207m 45m 26m R 91 4.5 0:12.77 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26706 www-data 20 0 196m 43m 34m S 47 4.3 0:15.19 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26583 www-data 20 0 197m 45m 35m S 33 4.5 0:19.08 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26787 www-data 20 0 206m 36m 18m R 25 3.7 0:00.41 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26661 www-data 20 0 207m 46m 26m S 13 4.6 0:19.87 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 1971 mysql 20 0 155m 57m 3952 S 8 5.7 383:57.81 /usr/sbin/mysqld 242 root 20 0 0 0 0 S 1 0.0 0:51.36 [kworker/3:1] 5711 root 20 0 139m 95m 580 S 1 9.5 0:41.30 /usr/local/bin/memcached -d -u root -m 128 -p 11211 19463 root 20 0 190m 3984 1284 S 1 0.4 0:02.66 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 29100 www-data 20 0 10928 5540 820 S 1 0.5 4:49.05 nginx: worker process vmstat 30 procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 16912 81456 90784 554172 0 0 4 6 3 2 11 1 87 1 0 0 16912 78036 91000 555356 0 0 38 34 1397 375 12 1 87 0 4 0 16912 31776 91528 557508 0 0 78 42 3197 487 45 1 52 1 1 0 16912 83356 91768 558576 0 0 35 56 2608 449 32 1 67 1 1 0 16912 81548 92040 559720 0 0 41 31 1243 432 8 1 91 1 2 0 16912 53056 92332 562744 0 0 105 33 2013 581 17 1 81 1 2 0 16912 73236 92552 564844 0 0 68 36 1968 615 16 1 82 1 0 0 16912 91612 92904 566676 0 0 69 35 1845 692 13 1 85 1 1 0 16912 71248 93180 568428 0 0 58 33 1952 604 15 1 82 1 1 0 16868 55952 93516 572660 1 0 144 42 1801 637 12 1 86 1 2 0 16868 48324 94416 577844 0 0 189 66 2058 702 17 1 80 2 1 0 16928 58644 94592 578184 0 2 160 49 2578 723 25 1 70 3 5 0 16928 22600 94980 580568 0 0 89 32 1496 361 13 0 85 1 0 0 16988 49256 94500 576396 0 2 41 37 1601 426 14 1 85 0 5 0 18084 24336 86032 502748 0 37 83 68 2989 562 42 1 56 0 1 0 18084 123604 86376 506996 0 0 118 41 2201 573 22 1 76 1 2 0 18084 126984 86752 508876 0 0 64 53 1620 490 13 1 85 1 2 0 18084 103104 87148 510768 0 0 71 37 2757 602 33 1 64 1

    This is the structure of my file: 1111111111111111111111111 2222222222222222222222222 3333333333333333333333333 4444444444444444444444444 5555555555555555555555555 6666666666666666666666666 7777777777777777777777777 8888888888888888888888888 9999999999999999999999999 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 0000000000000000000000000 And this is the code I'm using to read it into an array: using (StreamReader reader = new StreamReader(mapPath)) { string line; for (int i = 0; i < iMapHeight; i++) { if ((line = reader.ReadLine()) != null) { for (int j = 0; j < iMapWidth; j++) { iMap[i, j] = line[j]; } } } } I have done some debugging, and line[j] correctly iterates through each character in the currently read line. The problem lies with iMap[i, j]. After this block of code executes, this is the contents of iMap: - iMap {int[14, 25]} int[,] [0, 0] 49 int [0, 1] 49 int [0, 2] 49 int [0, 3] 49 int [0, 4] 49 int [0, 5] 49 int [0, 6] 49 int [0, 7] 49

  • Slow Memcached: Average 10ms memcached `get`

    - by Chris W.
    We're using Newrelic to measure our Python/Django application performance. Newrelic is reporting that across our system "Memcached" is taking an average of 12ms to respond to commands. Drilling down into the top dozen or so web views (by # of requests) I can see that some Memcache get take up to 30ms; I can't find a single use of Memcache get that returns in less than 10ms. More details on the system architecture: Currently we have four application servers each of which has a memcached member. All four memcached members participate in a memcache cluster. We're running on a cloud hosting provider and all traffic is running across the "internal" network (via "internal" IPs) When I ping from one application server to another the responses are in ~0.5ms Isn't 10ms a slow response time for Memcached? As far as I understand if you think "Memcache is too slow" then "you're doing it wrong". So am I doing it wrong? Here's the output of the memcache-top command: memcache-top v0.7 (default port: 11211, color: on, refresh: 3 seconds) INSTANCE USAGE HIT % CONN TIME EVICT/s GETS/s SETS/s READ/s WRITE/s cache1:11211 37.1% 62.7% 10 5.3ms 0.0 73 9 3958 84.6K cache2:11211 42.4% 60.8% 11 4.4ms 0.0 46 12 3848 62.2K cache3:11211 37.5% 66.5% 12 4.2ms 0.0 75 17 6056 170.4K AVERAGE: 39.0% 63.3% 11 4.6ms 0.0 64 13 4620 105.7K TOTAL: 0.1GB/ 0.4GB 33 13.9ms 0.0 193 38 13.5K 317.2K (ctrl-c to quit.) ** Here is the output of the top command on one machine: ** (Roughly the same on all cluster machines.

  • Which will give more free RAM to linux?

    - by Linda Thomas
    Trying to avoid some issues so I've been trying to learn vm. in kernel tuning but still a little confused even after googling. The lower background_ratio is the sooner the flushes? the lower dirty_ratio is the less dirty ram that is kept, right vm.dirty_ratio = 20 vm.dirty_background_ratio = 1 or vm.dirty_ratio = 60 vm.dirty_background_ratio = 20 or vm.dirty_ratio = 20 vm.dirty_background_ratio = 10 or vm.dirty_ratio = 20 vm.dirty_background_ratio = 5

    Looking at our Apache log I see normal requests like: 174.133.xxx.xxx - - [20/May/2010:17:36:44 -0700] "GET /index.html HTTP/1.1" 200 2004 but every so often i get a cluster of these w/out an IP address. ::1 - - [20/May/2010:18:47:21 -0700] "OPTIONS * HTTP/1.0" 200 - ::1 - - [20/May/2010:18:47:22 -0700] "OPTIONS * HTTP/1.0" 200 - ::1 - - [20/May/2010:18:47:23 -0700] "OPTIONS * HTTP/1.0" 200 - what do they mean and curious what causes them?

  • Configure spanning tree from HP to Cisco hardware

    - by Tim Brigham
    I have three switches I'd like to configure in a loop - a Cisco stack (3750s) and two HP 2900 series. Each is connected to the next with a 10 gig backplane of one form or another. How do I configure the spanning tree on these systems to make this function correctly? From the documents I've looked at it looks like I need to set both sets of hardware to use MST mode but I'm not sure past that point. The trunking, etc is all set up as needed. HP Switch 1 A4 connected to Cisco 1/0/1. HP Switch 2 B2 connected to Cisco 2/0/1. HP Switch 1 A2 connected to HP Switch 2 A1. HP Switch 1 show spanning-tree Multiple Spanning Tree (MST) Information STP Enabled : Yes Force Version : MSTP-operation IST Mapped VLANs : 1-4094 Switch MAC Address : 0021f7-126580 Switch Priority : 32768 Max Age : 20 Max Hops : 20 Forward Delay : 15 Topology Change Count : 352,485 Time Since Last Change : 2 secs CST Root MAC Address : 0018ba-c74268 CST Root Priority : 1 CST Root Path Cost : 200000 CST Root Port : 1 IST Regional Root MAC Address : 0021f7-126580 IST Regional Root Priority : 32768 IST Regional Root Path Cost : 0 IST Remaining Hops : 20 Root Guard Ports : TCN Guard Ports : BPDU Protected Ports : BPDU Filtered Ports : PVST Protected Ports : PVST Filtered Ports : | Prio | Designated Hello Port Type | Cost rity State | Bridge Time PtP Edge ----- --------- + --------- ---- ---------- + ------------- ---- --- ---- ...
