• Intel I217LM ethernet controller not detected by Ubuntu 12.04LTS

  - by Alexandr Kurilin

  My last installation of Ubuntu 12.04 on a machine using an ASUS Q87M-E motherboard with an Intel I217LM Ethernet controller has failed to detect the ethernet card. The only thing displayed by ifconfig -a is the loopback. I double-checked in the BIOS, and the controller should be online. $ rfkill list all 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no $ lspci 00:00.0 Host bridge: Intel Corporation Haswell DRAM Controller (rev 06) 00:01.0 PCI bridge: Intel Corporation Haswell PCI Express x16 Controller (rev 06) 00:02.0 VGA compatible controller: Intel Corporation Haswell Integrated Graphics Controller (rev 06) 00:03.0 Audio device: Intel Corporation Haswell HD Audio Controller (rev 06) 00:14.0 USB controller: Intel Corporation Lynx Point USB xHCI Host Controller (rev 04) 00:16.0 Communication controller: Intel Corporation Lynx Point MEI Controller #1 (rev 04) 00:16.3 Serial controller: Intel Corporation Lynx Point KT Controller (rev 04) 00:19.0 Ethernet controller: Intel Corporation Device 153a (rev 04) 00:1a.0 USB controller: Intel Corporation Lynx Point USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation Lynx Point HD Audio Controller (rev 04) 00:1d.0 USB controller: Intel Corporation Lynx Point USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation Lynx Point LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation Lynx Point 6-Port SATA AHCI Controller (rev 04) 00:1f.3 SMBus: Intel Corporation Lynx Point SMBus Controller (rev 04) $ lsmod Module Size Used by vesafb 13844 1 snd_hda_codec_realtek 224173 1 arc4 12529 2 joydev 17693 0 usbhid 47238 0 hid 99636 1 usbhid rfcomm 47604 0 rt73usb 31735 0 crc_itu_t 12707 1 rt73usb rt2x00usb 20808 1 rt73usb rt2x00lib 55326 2 rt73usb,rt2x00usb mac80211 506862 2 rt2x00usb,rt2x00lib cfg80211 205774 2 rt2x00lib,mac80211 eeepc_wmi 13109 0 bnep 18281 2 asus_wmi 24456 1 eeepc_wmi sparse_keymap 13890 1 asus_wmi psmouse 97485 0 bluetooth 180153 10 rfcomm,bnep ppdev 17113 0 snd_hda_intel 33719 6 snd_hda_codec 127706 2 snd_hda_codec_realtek,snd_hda_intel snd_seq_midi 13324 0 snd_hwdep 17764 1 snd_hda_codec snd_rawmidi 30748 1 snd_seq_midi serio_raw 13211 0 snd_pcm 97275 2 snd_hda_intel,snd_hda_codec snd_seq_midi_event 14899 1 snd_seq_midi snd_seq 61929 2 snd_seq_midi,snd_seq_midi_event snd_timer 29990 2 snd_pcm,snd_seq snd_seq_device 14540 3 snd_seq_midi,snd_rawmidi,snd_seq parport_pc 32866 1 snd 79041 21 snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_rawmidi,snd_pcm,snd_seq,snd_timer,snd_seq_device video 19651 0 soundcore 15091 1 snd wmi 19256 1 asus_wmi snd_page_alloc 18529 2 snd_hda_intel,snd_pcm mac_hid 13253 0 lp 17799 0 parport 46562 3 ppdev,parport_pc,lp $ ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1091 errors:0 dropped:0 overruns:0 frame:0 TX packets:1091 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:80048 (80.0 KB) TX bytes:80048 (80.0 KB) wlan0 Link encap:Ethernet HWaddr 00:fd:07:91:a8:b9 inet addr:172.16.42.4 Bcast:172.16.42.255 Mask:255.255.255.0 inet6 addr: fe80::2fd:7ff:fe91:a8b9/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:56644 errors:0 dropped:0 overruns:0 frame:0 TX packets:36417 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:85270918 (85.2 MB) TX bytes:3413849 (3.4 MB) additionally, running sudo lshw -C network returns: *-network UNCLAIMED description: Ethernet Controller [...] I'm pretty stumped at this point. This doesn't sound like a very uncommon ethernet controller and I figured it would be picked up by the system. Does anybody have advice for how to deal with this? Anything specific I should look into to figure out what could be causing this? Edit: It seems that following the guide on the Intel e1000e drivers page allowed the card to start working. Is this a real fix or is there a better way?

• Slow wired internet connection on Realtek RTL8168-8111 (Rev 6)

  - by Mark

  I keep on seeing issues people are having with their wireless. I am having an issue with being wired into my router. I installed Ubuntu 11.10 the other day, on my custom PC. The motherboard I have installed on this PC is an ASUS P8H61-M. The issue I am having is with my speed. I have a dual boot, windows 7 and the new Ubuntu. On my Windows install I am getting test speeds from Speakeasy at 17Mbps and actual downloads around 2-3MB/s. With Ubuntu, I am getting test speeds from Speakeasy at 1.14Mbps and actual downloads around 60KB/s. I have disabled IPv6 and am no using GoogleDNS for my DNS, but it hasn't resolved the issue. I have scanned my router (WRT54GS Linksys) to disable IPv6 connections, and I am not seeing any option for that. I cannot figure out why I am getting such sluggish internet connection. Any help to resolve would be great! I performed an iconfig -a with these results: mark@Mark-ASUS:~$ ifconfig -a eth0 Link encap:Ethernet HWaddr f4:6d:04:d1:2c:4e inet addr:192.168.1.103 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::f66d:4ff:fed1:2c4e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:21888 errors:0 dropped:21888 overruns:0 frame:21888 TX packets:21068 errors:0 dropped:90 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:26348337 (26.3 MB) TX bytes:2217140 (2.2 MB) Interrupt:46 Base address:0xc000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:7 errors:0 dropped:0 overruns:0 frame:0 TX packets:7 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:952 (952.0 B) TX bytes:952 (952.0 B) My specs are: mark@Mark-ASUS:~$ sudo lspci -nn 04:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.

The other issue I am noticing is sometimes my connection disconnects all together, for about a minute, then it reconnects.

• Schizophrenic Ubuntu 12.10-12.04: Atheros 922 PCI WIFI is disabled in Unity but enabled in terminal - How to getit to work?

  - by zewone

  I am trying to get my PCI Wireless Atheros 922 card to work. It is disabled in Unity: both the network utility and the desktop (see screenshot http://www.amisdurailhalanzy.be/Screenshot%20from%202012-10-25%2013:19:54.png) I tried many different advises on many different forums. Installed 12.10 instead of 12.04, enabled all interfaces... etc. I have read about the aht9 driver... The terminal shows no hw or sw lock for the Atheros card, nevertheless, it is still disabled. Nothing worked so far, the card is still disabled. Any help is much appreciated.

• How do I get to work my Atheros AR9485 Wireless card in Ubuntu 14.04 LTS?

  - by Ivan Kreimer

  I've recently installed Ubuntu 14.04 LTS in my ASUS D550CA, and so far things have gone great. The only problem I've got is the Wi-Fi. It doesn't work. I've got an Qualcomm Atheros AR9485. I've tried installing the drivers, but the sytem says it doesn't find any. So I started looking around this forum for solutions. I've read every single post from this forum about my Wi-Fi network adapter, and I've found nothing that solves my problem. Let me give you some info about my configuration. Disclaimer: my configuration is in spanish, so if you don't understand something you can either use Google translate, or use your imagination. :D When I run $ sudo lshw -C network this is what I get: *-network DEACTIVATED descripción: Interfaz inalámbrica producto: AR9485 Wireless Network Adapter fabricante: Qualcomm Atheros id físico: 0 información del bus: pci@0000:02:00.0 nombre lógico: wlan0 versión: 01 serie: 28:e3:47:5c:5d:3f anchura: 64 bits reloj: 33MHz capacidades: pm msi pciexpress bus_master cap_list rom ethernet physical wireless configuración: broadcast=yes driver=ath9k driverversion=3.13.0-34-generic firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11bgn recursos: irq:17 memoria:f7d00000-f7d7ffff memoria:f7d80000-f7d8ffff *-network descripción: Ethernet interface producto: RTL8101E/RTL8102E PCI Express Fast Ethernet controller fabricante: Realtek Semiconductor Co., Ltd. id físico: 0.2 información del bus: pci@0000:03:00.2 nombre lógico: eth0 versión: 06 serie: e0:3f:49:ce:57:49 tamaño: 100Mbit/s capacidad: 100Mbit/s anchura: 64 bits reloj: 33MHz capacidades: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuración: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=full firmware=rtl8402-1_0.0.1 10/26/11 ip=181.165.245.39 latency=0 link=yes multicast=yes port=MII speed=100Mbit/s recursos: irq:41 ioport:e000(size=256) memoria:f0004000-f0004fff memoria:f0000000-f0003fff At the beginning, you'll see that it says "*-network DEACTIVATED" (or at least that's what I translated), is that something bad?

• Access denied error while mounting a shared folder?

  - by SSH

  I am a linux newbie and I have a very basic question. I have three machines - machineA 10.108.24.132 machineB 10.108.24.133 machineC 10.108.24.134 and all those machines have Ubuntu 12.04 installed in it and I have root access to all those three machines. Now I am supposed to do below things in my above machines - Create mount point /opt/exhibitor/conf Mount the directory in all servers. sudo mount <NFS-SERVER>:/opt/exhibitor/conf /opt/exhibitor/conf/ I have already created /opt/exhibitor/conf directory in all those three machines as mentioned above. Now I am trying to create a Mount Point on all those three machines. So I followed the below process - Install NFS support files and NFS kernel server in all the above three machines $ sudo apt-get install nfs-common nfs-kernel-server Create the shared directory in all the above three machines $ mkdir /opt/exhibitor/conf/ Edited the /etc/exports and added the entry like this in all the above three machines - # /etc/exports: the access control list for filesystems which may be exported # to NFS clients. See exports(5). # # Example for NFSv2 and NFSv3: # /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check) # # Example for NFSv4: # /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check) # /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check) # /opt/exhibitor/conf/ 10.108.24.*(rw) Run exportfs in all the above three machines root@machineA:/# exportfs -rv exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check' specified for export "10.108.24.*:/opt/exhibitor/conf/". Assuming default behaviour ('no_subtree_check'). NOTE: this default has changed since nfs-utils version 1.0.x exporting 10.108.24.*:/opt/exhibitor/conf Now I did showmount on machineA root@machineA:/# showmount -e 10.108.24.132 Export list for 10.108.24.132: /opt/exhibitor/conf 10.108.24.* And also I have started the NFS server like this in all the above three machines - sudo /etc/init.d/nfs-kernel-server start And now when I did this, I am getting an error - root@machineA:/# sudo mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf/ mount.nfs: access denied by server while mounting 10.108.24.132:/opt/exhibitor/conf I have also tried doing the same thing from machineB and machineC as well and still I get the same error- root@machineB:/# sudo mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf/ root@machineC:/# sudo mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf/ Did my /etc/exports file looks good? As I have the same content in all the three machines. And also are there any logs related to NFS which I can see to find any clues? Any idea what wrong I am doing here? UPDATE:- So my etc/exports files would be like this in all the three machines - # /etc/exports: the access control list for filesystems which may be exported # to NFS clients. See exports(5). # # Example for NFSv2 and NFSv3: # /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check) # # Example for NFSv4: # /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check) # /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check) # /opt/exhibitor/conf/ 10.108.24.132(rw) /opt/exhibitor/conf/ 10.108.24.133(rw) /opt/exhibitor/conf/ 10.108.24.134(rw) Just a quick check - The IP Address that I am taking for each machine as mentioned above is like this - root@machineB:/# ifconfig eth0 Link encap:Ethernet HWaddr 00:50:56:ad:5b:a7 inet addr:10.108.24.133 Bcast:10.108.27.255 Mask:255.255.252.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5696812 errors:0 dropped:12462 overruns:0 frame:0 TX packets:5083427 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7904369145 (7.9 GB) TX bytes:601844910 (601.8 MB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:187144 errors:0 dropped:0 overruns:0 frame:0 TX packets:187144 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:24012302 (24.0 MB) TX bytes:24012302 (24.0 MB) Here the IP Address that I am taking for machineB is 10.108.24.133.

• Sqlite3 "chained" query

  - by Arrieta

  I need to create a configuration file from a data file that looks as follows: MAN1_TIME '01-JAN-2010 00:00:00.0000 UTC' MAN1_RX 123.45 MAN1_RY 123.45 MAN1_RZ 123.45 MAN1_NEXT 'MAN2' MAN2_TIME '01-MAR-2010 00:00:00.0000 UTC' MAN2_RX 123.45 [...] MAN2_NEXT 'MANX' [...] MANX_TIME [...] This file describes different "legs" of a trajectory. In this case, MAN1 is chained to MAN2, and MAN2 to MANX. In the original file, the chains are not as obvious (i.e., they are non-sequential). I've managed to read the file and store in an Sqlite3 database (I'm using the Python interface). The table is stored with three columns: Id, Par, and Val; for instance, Id='MAN1', Par='RX', and Val='123.45'. I'm interested in querying such database for obtaining the information related to 'n' legs. In English, that would be: "Select RX,RY,RZ for the next five legs starting on MAN1" So the query would go to MAN1, retrieve RX, RY, RZ, then read the parameter NEXT and go to that Id, retrieve RX, RY, RZ; read the parameter NEXT; go to that one ... like this five times. How can I pass such query with "dynamic parameters"? Thank you.

• Wireless Connected But No Internet Connection (Ubuntu 12.04)

  - by Zxy

  I am using same network for 2 days and everything was normal. However, today even though it shows me as connected to the network, I do not have internet connection. If I use ethernet cable instead of wireless, I am still able to connect to the internet. Also my friends are able to connect to the wireless network and they can get internet connection. I did not update or install anything since yesterday. Therefore I do not have any idea why it is happening. Here is some information about my connection: I will be appreciate to any kind of help. root@ghostrider:/etc/resolvconf# ping 127.0.0.1 PING 127.0.0.1 (127.0.0.1) 56(84) bytes of data. 64 bytes from 127.0.0.1: icmp_req=1 ttl=64 time=0.042 ms 64 bytes from 127.0.0.1: icmp_req=2 ttl=64 time=0.023 ms 64 bytes from 127.0.0.1: icmp_req=3 ttl=64 time=0.036 ms 64 bytes from 127.0.0.1: icmp_req=4 ttl=64 time=0.040 ms ^C --- 127.0.0.1 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 2998ms rtt min/avg/max/mdev = 0.023/0.035/0.042/0.008 ms root@ghostrider:/etc/resolvconf# ping 192.168.1.3 PING 192.168.1.3 (192.168.1.3) 56(84) bytes of data. ^C --- 192.168.1.3 ping statistics --- 19 packets transmitted, 0 received, 100% packet loss, time 18143ms root@ghostrider:/etc/resolvconf# ping 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data. ^C --- 8.8.8.8 ping statistics --- 11 packets transmitted, 0 received, 100% packet loss, time 10079ms root@ghostrider:/etc/resolvconf# cat /etc/lsb-release; uname -a DISTRIB_ID=Ubuntu DISTRIB_RELEASE=12.04 DISTRIB_CODENAME=precise DISTRIB_DESCRIPTION="Ubuntu 12.04 LTS" Linux ghostrider 3.2.0-24-generic-pae #39-Ubuntu SMP Mon May 21 18:54:21 UTC 2012 i686 i686 i386 GNU/Linux root@ghostrider:/etc/resolvconf# lspci -nnk | grep -iA2 net 03:00.0 Ethernet controller [0200]: Atheros Communications Inc.

• Errors when switching to specific static IP

  - by michaelc

  I had a Fedora box running using my static IP 69.169.136.6, etc, all configured according to what the ISP required. Just recently the hard drive failed (and I should have been keeping better backups) - while it is being recovered I would like to put up a webpage on my Archlinux PC explaining the problem - I presently do not have sufficient access to change the DNS record assigned to the domain. When I change my ip address while my system is running to 69.169.136.6, ifconfig reports the new ip address, but http://whatismyip.com/ does not. When I change it and reboot, I can't ping - the message I recieve is "connect: Network is unreachable" (when given one of google.com 's IP addresses - hostnames give me ping: unknown host xxx). Until I have access to the DNS system, what can I do to make this work? Edit: With new IP address, same problem, IP is now 69.169.136.29. Some commands might be useful: #ping 69.169.136.1 PING 69.169.136.1 (69.169.136.1) 56(84) bytes of data. 64 bytes from 69.169.136.1: icmp_seq=1 ttl=64 time=0.377 ms #ping 69.169.190.211 connect: Network is unreachable #ping 208.72.160.67 connect: Network is unreachable #ifconfig eth0 Link encap:Ethernet HWaddr 00:E0:4D:97:23:9B inet addr:69.169.136.29 Bcast:69.169.137.255 Mask:255.255.254.0 inet6 addr: fe80::2e0:4dff:fe97:239b/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:132091 errors:0 dropped:0 overruns:0 frame:0 TX packets:17 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:9635179 (9.1 Mb) TX bytes:1322 (1.2 Kb) Interrupt:29 Base address:0x6000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:48 errors:0 dropped:0 overruns:0 frame:0 TX packets:48 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2480 (2.4 Kb) TX bytes:2480 (2.4 Kb) #ip route 69.169.136.0/23 dev eth0 proto kernel scope link src 69.169.136.29 #cat /etc/resolv.conf # Generated by dhcpcd #nameserver 208.67.222.222 #nameserver 208.67.220.220 nameserver 69.169.190.211 nameserver 208.72.160.67 # /etc/resolv.conf.tail can replace this line Update: have new static IP addresses, verified to work in Windows...

• eth0:0 is configured but not listed in ifconfig output

  Hello. I have the following problem: My server was given two IPs from [b]different[/b] subnets. Now I am trying to configure the system to work properly. I have created [root@server ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 # Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) HWADDR=00:30:48:DA:B1:0E DEVICE=eth0 BOOTPROTO=none BROADCAST=79.174.69.255 IPADDR=79.174.69.241 NETMASK=255.255.254.0 NETWORK=79.174.68.0 ONBOOT=yes GATEWAY=79.174.68.1 TYPE=Ethernet [root@server ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0:0 # Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) HWADDR=00:30:48:DA:B1:0E DEVICE=eth0 BOOTPROTO=none BROADCAST=79.174.69.255 IPADDR=79.174.71.74 NETMASK=255.255.255.0 NETWORK=79.174.71.1 ONBOOT=yes GATEWAY=79.174.71.1 TYPE=Ethernet But both after "service network restart" and after "reboot" [root@server ~]# ifconfig eth0 Link encap:Ethernet HWaddr 00:30:48:DA:B1:0E inet addr:79.174.71.74 Bcast:79.174.71.255 Mask:255.255.255.0 inet6 addr: fe80::230:48ff:feda:b10e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:910284 errors:0 dropped:0 overruns:0 frame:0 TX packets:2924 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:257964879 (246.0 MiB) TX bytes:232450 (227.0 KiB) Memory:df220000-df240000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:27 errors:0 dropped:0 overruns:0 frame:0 TX packets:27 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:6976 (6.8 KiB) TX bytes:6976 (6.8 KiB) Device eth0:0 is not shown as active.

Also it is strange, that IP address assigned to eth0:0 in config file is used by eth0. /var/log/messages shows nothing about network configuration errors on either eth0 or eth0:0. system-config-network seem to understand all settings correctly and resaves them ok also. "ifup eth0:0" executes ok, but ifconfig afterwards shows no eth0:0 device after that. What did I do wrong? May be the problem is that IPs are from different subnets?

• Cliq Wireless questions

  Heres the deal: I am by no means a Linux expert, even less when it comes to the Android OS but lets see if we can't solve this problem. The problem I am having is that on the Cliq we have a broadcom chip. In order to use the wireless card you must first insert the module into the kernel. Fine: # insmod /system/lib/dhd.ko insmod /system/lib/dhd.ko # lsmod lsmod dhd 164936 0 - Live 0xbf000000 # BUT netcfg (or ifconfig in busybox) does not recognize that there is a wireless adapter there: # netcfg netcfg lo UP 127.0.0.1 255.0.0.0 0x00000049 dummy0 DOWN 0.0.0.0 0.0.0.0 0x00000082 rmnet0 UP 14.67.164.2 255.255.255.252 0x00001043 rmnet1 DOWN 0.0.0.0 0.0.0.0 0x00001002 rmnet2 DOWN 0.0.0.0 0.0.0.0 0x00001002 usb0 DOWN 0.0.0.0 0.0.0.0 0x00001002 # busybox ifconfig busybox ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:282 errors:0 dropped:0 overruns:0 frame:0 TX packets:282 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:18754 (18.3 KiB) TX bytes:18754 (18.3 KiB) rmnet0 Link encap:Ethernet HWaddr EE:83:E8:B4:4A:ED inet addr:14.x.x.x Bcast:14.67.164.3 Mask:255.255.255.252 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7148 errors:0 dropped:0 overruns:0 frame:0 TX packets:7659 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2609236 (2.4 MiB) TX bytes:908575 (887.2 KiB) # For giggles if we attempt to launch wpa_supplicant anyways we get this: # wpa_supplicant -Dwext -ieth0 -c/data/misc/wifi/wpa_supplicant.conf wpa_supplicant -Dwext -ieth0 -c/data/misc/wifi/wpa_supplicant.conf ioctl[SIOCSIWPMKSA]: No such device ioctl[SIOCSIWMODE]: No such device Could not configure driver to use managed mode ioctl[SIOCGIFFLAGS]: No such device Could not set interface 'eth0' UP ioctl[SIOCGIWRANGE]: No such device ioctl[SIOCGIFINDEX]: No such device CTRL-EVENT-STATE-CHANGE id=-1 state=0 ioctl[SIOCSIWENCODEEXT]: No such device ioctl[SIOCSIWENCODE]: No such device ioctl[SIOCSIWENCODEEXT]: No such device ioctl[SIOCSIWENCODE]: No such device ioctl[SIOCSIWENCODEEXT]: No such device ioctl[SIOCSIWENCODE]: No such device ioctl[SIOCSIWENCODEEXT]: No such device ioctl[SIOCSIWENCODE]: No such device ioctl[SIOCSIWAUTH]: No such device WEXT auth param 7 value 0x0 - Failed to disable WPA in the driver. ioctl[SIOCSIWAUTH]: No such device WEXT auth param 5 value 0x0 - ioctl[SIOCSIWAUTH]: No such device WEXT auth param 4 value 0x0 - ioctl[SIOCSIWAP]: No such device ioctl[SIOCGIFFLAGS]: No such device # In dmesg we get: <4>[18300.494065] dhd_oob_enable_intr : enable <4>[18305.019976] dhd_net_start failed bus is not ready <4>[18305.020278] dhdsdio_probe: dhd_net_start failed! Do I need to specify the firmware with insmod? Why are we trying to control the interface manually instead of through the Android API? The Android API doesn't support ad-hoc connections as far as I can tell. The card, I am sure, most certainly can.

• VPN - force a selective range of ip to run on VPN (linux)

  - by Francesco

  Preface: I know there are similar question here and there however I'm a kind of newbie on Net stuff so I need an answer on this specific scenario, hoping that can help others too as it is a common problem Let say I cannot do anything on the local switch to change the local ip range, I don't want to use any complicate trick as use VMachine to hide the local ip range but I want to use net tools to solve the issue. Scenario my local net assign me an IP of this class 192.168.1.xxx (ex. 192.168.1.116) and my VPN (VPNC) assign me IP of same class 192.168.1.xxx (ex. 192.168.1.247) Obviously I need VPN to access local address (ex. 192.168.1.100) but when I open any address of the class 192.168.1.xx the route point to my local net and not to the VPN ones. I'm on linux and i'd like gui solution (network manager) in case it is not possible let play with route command. here what network manager offer me: Here my actual route once connected to the VPN: Here some route information (route -n) Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 wlan0 182.71.21.106 192.168.1.1 255.255.255.255 UGH 0 0 0 wlan0 182.71.21.106 192.168.1.1 255.255.255.255 UGH 0 0 0 wlan0 192.168.1.0 0.0.0.0 255.255.255.0 U 9 0 0 wlan0 192.168.1.246 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 Here my ifconfig : ppp0 Link encap:Point-to-Point Protocol inet addr:192.168.1.247 P-t-P:192.168.1.246 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1400 Metric:1 RX packets:3415 errors:0 dropped:0 overruns:0 frame:0 TX packets:2525 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:3682328 (3.6 MB) TX bytes:402315 (402.3 KB) wlan0 Link encap:Ethernet HWaddr 4c:eb:42:06:a3:a6 inet addr:192.168.1.116 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::4eeb:42ff:fe06:a3a6/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:72598 errors:0 dropped:0 overruns:0 frame:0 TX packets:42300 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:76000532 (76.0 MB) TX bytes:13919400 (13.9 MB) The Question So basically I would like to add a rule to force this particular address (192.168.1.100) on the VPN and not on my local net

• Connecting to localhost resolves 127.0.0.1 but connects with external IP [Linux, Debian]

  - by skgsergio

  I'm having a problem with a dedicated server, I don't known if it's the default behavior but this is the problem: If I connect to a service located on the server with localhost the service gets as source IP the external IP. Let me show an example, I use netcat for listening on 127.0.0.1:4444 xxxxxx # nc -vv -l -s 127.0.0.1 -p 4444 listening on [127.0.0.1] 4444 ... Lets check if it's ok: xxxxxx ~ # netstat -atnp | grep 4444 tcp 0 0 127.0.0.1:4444 0.0.0.0:* LISTEN 14038/nc Ok lets connect: xxxxxx ~ # nc -vv 127.0.0.1 4444 localhost [127.0.0.1] 4444 (?) open Return to the tty that have the listening process and I get this: connect to [127.0.0.1] from xxxxxx.net [176.31.xxx.xx] 50354 So that's the problem.

• ubuntu eth0 not reconnecting after cable unplugged

  - by Alex

  I'm running kubuntu 9.10 w/ gnome, I have a static IP defined in /etc/network/interfaces When I unplugged my network cable and rebooted, then reconnected the network cable I was not able to connect. I tried using sudo ifup eth0, and then ifconfig and it seemed as though the IP address had been assigned and I was connected, but I wasn't. I then did ifdown eth0, and again ifup eth0. For some reason I'm not able to access the network. Furthermore, I also attempted to connect via wlan, and was able to connect to the wireless network, but cannot "see" the network. I can't transfer data or access the internet or anything on the network including the router. How do I resolve this? topsy@monolyth:~$ ifconfig eth0 Link encap:Ethernet HWaddr 00:1c:25:1c:df:70 inet addr:192.168.1.145 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::21c:25ff:fe1c:df70/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5720 errors:0 dropped:0 overruns:0 frame:0 TX packets:565 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:378035 (378.0 KB) TX bytes:46832 (46.8 KB) Memory:fe000000-fe020000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:4 errors:0 dropped:0 overruns:0 frame:0 TX packets:4 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:240 (240.0 B) TX bytes:240 (240.0 B) By access the network I mean the local network as well as the internet. topsy@monolyth:~$ ping 192.168.1.1 PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data. 64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=9.14 ms 64 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=1.24 ms 64 bytes from 192.168.1.1: icmp_seq=3 ttl=64 time=1.01 ms 64 bytes from 192.168.1.1: icmp_seq=4 ttl=64 time=1.00 ms [snip... all OK, icmp_seq from 5-30, time between 0.981-1.25ms] ^C --- 192.168.1.1 ping statistics --- 30 packets transmitted, 30 received, 0% packet loss, time 29035ms rtt min/avg/max/mdev = 0.971/1.300/9.140/1.458 ms topsy@monolyth:~$ route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 link-local * 255.255.0.0 U 1000 0 0 eth0 default 192.168.1.1 0.0.0.0 UG 100 0 0 eth0 root@monolyth:~# cat /etc/resolv.conf # Generated by NetworkManager

• OpenVPN not sending traffic to internet?

  - by coleifer

  I've set up openvpn on my pi and am running into a small issue. I can connect to the VPN server and ping it just fine, and I can also connect to other machines on my local network. However I am unable, when connected to the VPN, to reach the outside world (either by name lookup or IP). here are the details: On the server the tun0 interface: tun0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1500 inet 10.8.0.1 netmask 255.255.255.255 destination 10.8.0.2 unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 100 (UNSPEC) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 I can ping it just fine: # ping -c 3 10.8.0.1 PING 10.8.0.1 (10.8.0.1) 56(84) bytes of data. 64 bytes from 10.8.0.1: icmp_seq=1 ttl=64 time=0.159 ms 64 bytes from 10.8.0.1: icmp_seq=2 ttl=64 time=0.155 ms 64 bytes from 10.8.0.1: icmp_seq=3 ttl=64 time=0.156 ms --- 10.8.0.1 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2002ms Routing table # ip route show default via 192.168.1.1 dev eth0 metric 204 10.8.0.0/24 via 10.8.0.2 dev tun0 10.8.0.2 dev tun0 proto kernel scope link src 10.8.0.1 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.6 metric 204 I also have ip traffic forwarding: net.ipv4.ip_forward = 1 I do not have any custom iptables rules (that I'm aware of). On the client, I can connect to the VPN. Here is my tun0: tun0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1500 inet 10.8.0.6 netmask 255.255.255.255 destination 10.8.0.5 unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 100 (UNSPEC) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 21 bytes 1527 (1.4 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 And on the client I can ping it: sudo ping -c 3 10.8.0.6 PING 10.8.0.6 (10.8.0.6) 56(84) bytes of data. 64 bytes from 10.8.0.6: icmp_seq=1 ttl=64 time=0.035 ms 64 bytes from 10.8.0.6: icmp_seq=2 ttl=64 time=0.026 ms 64 bytes from 10.8.0.6: icmp_seq=3 ttl=64 time=0.032 ms --- 10.8.0.6 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 1998ms rtt min/avg/max/mdev = 0.026/0.031/0.035/0.003 ms I can ssh from the client into another server on my LAN (192.168.1.x), however I cannot reach anything outside my LAN. Here's some of the server logs at the bottom of this gist: https://gist.github.com/coleifer/6ef95c3008f130249933/edit I am frankly out of ideas! I don't think it's my client because both my laptop and my phone (which has an openvpn client) exhibit the same behavior. I had OpenVPN installed on this pi before using debian and it worked, so I don't think it's my router but of course anything is possible.

• Centos does not open port/s after the rule/s are appended

  - by Charlie Dyason

  So after some battling and struggling with the firewall, i see that I may be doing something or the firewall isnt responding correctly there is has a port filter that is blocking certain ports. by the way, I have combed the internet, posted on forums, done almost everything and now hence the website name "serverfault", is my last resort, I need help What I hoped to achieve is create a pptp server to connect to with windows/linux clients UPDATED @ bottom Okay, here is what I did: I made some changes to my iptables file, giving me endless issues and so I restored the iptables.old file contents of iptables.old: # Firewall configuration written by system-config-firewall # Manual customization of this file is not recommended. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT after iptables.old restore(back to stock), nmap scan shows: nmap [server ip] Starting Nmap 6.00 ( nmap.org ) at 2013-11-01 13:54 SAST Nmap scan report for server.address.net ([server ip]) Host is up (0.014s latency).

• pptpd configuration

  - by Ian R.

  I would like a little help on configuring pptp so I can use my server as a vpn server since I have 10 ip's on it and I travel a lot so that would really help me and my partners. I managed to install everything needed but my vpn client fails to connect due to some reason that I cannot understand. I know there are 2 files in pptp that you're supposed to edit so I will post my 2 files here: /etc/ppp/pptpd-options name pptpd refuse-pap refuse-chap refuse-mschap require-mschap-v2 require-mppe-128 proxyarp nodefaultroute lock nobsdcomp /etc/pptpd.conf option /etc/ppp/pptpd-options logwtmp localip xx.158.177.231 remoteip xx.158.177.103,xx.158.177.116,xx.158.177.121,xx.158.177.124,xx.158.177.125,xx.158.177.131,xx.158.177.134,xx.158.177.139,xx.158.177.142,xx.158.177.145 interfaces file eth0 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.231 Bcast:xx.158.177.255 Mask:255.255.254.0 inet6 addr: xx80::216:3eff:fe51:31ba/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:56352 errors:0 dropped:0 overruns:0 frame:0 TX packets:3xx15 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4884030 (4.8 MB) TX bytes:6780974 (6.7 MB) Interrupt:16 eth0:1 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.103 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:2 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.116 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:3 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.121 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:4 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.124 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:5 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.125 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:6 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.131 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:7 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.134 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:8 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.139 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:9 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.142 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:10 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.145 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:3 errors:0 dropped:0 overruns:0 frame:0 TX packets:3 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:286 (286.0 B) TX bytes:286 (286.0 B)

• Routing all data through an VPN tunnel with ppp

  I'm trying to create a VPN tunnel that forwards all data from the local machine to the VPN server. I'm using ppp-2.4.5 for this with the following configuration: pty "pptp <VPNServer> --nolaunchpppd" name <my login name> remotename PPTP usepeerdns require-mppe-128 file /etc/ppp/options.pptp persist maxfail 0 holdoff 5 I have a script in if-up.d with the following content: route del default eth0 route add default dev ppp0 Before starting the VPN tunnel my routing looks like: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 2 0 0 eth0 127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo 192.168.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 After starting the tunnel (via pon) it looks like: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0 12.34.56.1 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo 192.168.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 Now the problem is, that the VPN tunnel seems to be looped into itself. If I run ifconfig after a few seconds without any traffic: eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.0.10 netmask 255.255.0.0 broadcast 192.168.255.255 ether 00:01:2e:2f:ff:35 txqueuelen 1000 (Ethernet) RX packets 39931 bytes 6784614 (6.4 MiB) RX errors 0 dropped 90 overruns 0 frame 0 TX packets 34980 bytes 7633181 (7.2 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt 20 memory 0xfbdc0000-fbde0000 ppp0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1496 inet 12.34.56.78 netmask 255.255.255.255 destination 12.34.56.1 ppp txqueuelen 3 (Point-to-Point Protocol) RX packets 7 bytes 94 (94.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 782863 bytes 349257986 (333.0 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 It states that already over 300 MiB have been send, ppp0 is only online since a few seconds and the connection isn't working anyway. Can someone please help me to fix the routing table, so that the traffic from ppp0 is not send again through ppp0 but instead goes to the remote server?

• Second network card configuration not working.

  - by Sebas

  I have 4 servers running Centos 5. All of them have two ethernet network cards. I have configured 192.168.1.x IP addresses on their eth0 card. They are all connected to the same switch using their eth0 card and they are all working. I have configured 10.72.11.x IP addresses on their eth1 card.They are all connected to the same switch - a different one from the switch used with eth0 card - using their eth1 card and they are NOT all working. Their configuration files is like: DEVICE=eth1 BOOTPROTO=static IPADDR=10.72.11.236 BROADCAST=10.72.11.191 NETMASK=255.255.255.192 NETWORK=10.72.11.128 HWADDR=84:2B:2B:55:4B:98 IPV6INIT=yes IPV6_AUTOCONF=yes ONBOOT=yes The interfase is starting and configured as I need.

• Routing table with two NIC adapters in libvirt/KVM

  - by lzap

  I created a virtual NAT network (192.168.100.0/24 network) in my libvirt and new guest with two interfaces - one in this network, one as bridged (10.34.1.0/24 network) to the local LAN. The reason for that is I need to have my own virtual network for my DHCP/TFTP/DNS testing and still want to access my guest externally from my LAN. On both networks I have working DHCP, both giving them IP addresses. When I setup NAT port forwarding (e.g. for ssh), I can connect to the eth0 (virtual network), everything is fine. But when I try to access the eth1 via bridged interface, I have no response. I guess I have problem with my routing table - outgoing packets are routed to the virtual NAT network (which has access to the machine I am connecting from - I can ping it). But I am not sure if this setup is correct. I think I need to add something to my routing table. # ifconfig eth0 Link encap:Ethernet HWaddr 52:54:00:B4:A7:5F inet addr:192.168.100.14 Bcast:192.168.100.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:feb4:a75f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:16468 errors:0 dropped:27 overruns:0 frame:0 TX packets:6081 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:22066140 (21.0 MiB) TX bytes:483249 (471.9 KiB) Interrupt:11 Base address:0x2000 eth1 Link encap:Ethernet HWaddr 52:54:00:DE:16:21 inet addr:10.34.1.111 Bcast:10.34.1.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:fede:1621/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:34 errors:0 dropped:0 overruns:0 frame:0 TX packets:189 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4911 (4.7 KiB) TX bytes:9 # route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.100.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.34.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 1002 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1003 0 0 eth1 0.0.0.0 192.168.100.1 0.0.0.0 UG 0 0 0 eth0 Network I am trying to connect from is different than network the hypervisor is connected to: 10.36.0.0. But it is accessible from that network. So I tried to add new route rule: route add -net 10.36.0.0 netmask 255.255.0.0 dev eth1 And it is not working. I thought setting correct interface would be sufficient. What is needed to get my packets coming through?

• Windows doesn't get access to internet though linux easily does

  - by flashnik

  We have a very interesting problem. The network is configured in this way: internet is connected to Trendnet switch TS DHCP server at 192.168.0.1 running on Ubuntu (S) is connected to internet switch DNS is also configured on 192.168.0.1 on S D-Link Wi-Fi boosters are connected to switch TS PCs use D-Link PCI-E Wi-Fi cards to get access to network PCs have both Ubuntu and Windows 7 There are about 40 PCs. When PC is booted to Ubuntu it easily gets access to internet. But when it's booted to Windows 7, it gets a valid IP-address, but doesn't get access to internet. The address, mask, DNS, GW-address are totally the same as when it's booted under Ubuntu. The S is reacheble and pingable. Sometimes when we are lucky the PC gets access to Internet, but after rebooting it can lose it. When PC under Windows has access, it has totally the same settings as when it doesn't. What can be done? UPDATE I shared a dropbox with 2 captures of traffic. Ping.pcap is a capture of pinging 8.8.8.8. And google-browser.pcap is a capture of opening a google.com in a browser, both of them are in tcpdump formats and made by Wireshark on Win PC. The MAC of Win PC ends on b7:63 and IP is 192.168.0.130.

But according to man ip-route the src parameter should only set the source-ip if this route is chosen. But if this route is chosen then the source-ip would be that anyway.

• [CentOS 4.8] nslookup resolves domains to IPs, but I can't get a response to pings to external servers

  - by Beco

  I have a fresh install of CentOS 4.8 running on an internal development server. I haven't done anything to it besides setting up sudoers and SSH. I can SSH into the server and from there resolve domains to IPs and ping internal servers, but for some reason I don't get any response from pinging external servers. The software firewall is disabled, and the problem is present with both static and DHCP-assigned network configurations. The network domain controller is a Windows Server 2003 box. $ nslookup google.com Server: 10.254.2.5 Address: 10.254.2.5#53 Non-authoritative answer: Name: google.com Address: 74.125.47.147 Name: google.com Address: 74.125.47.99 <etc...> 10.254.2.5 is the Win2K3 server. $ ping google.com PING google.com (74.125.47.106) 56(84) bytes of data.
