| Farva | On our one server machine, we are running a few different IPs, on one IP, everyone connects just fine (iftop example-http://gyazo.com/2e962762f24c46a4b533a953aed9bc95), on the other, people are showing one bar of connection and are lagging heavily. (same person on the other IP: http://gyazo.com/3837b0e2aec3339ca045078ca9765dd8) This is a E3 gaming server. How do I trouble shoot this? | 09:16 |
| WhiteIntel | hello I have a problem with my ubuntu server client: when I try to connect I get this error: RTNETLINK answers: Network is unreachable | 10:29 |
| WhiteIntel | Mon Oct 27 20:29:06 2014 ERROR: Linux route add command failed: external program exited with error status: 2 | 10:29 |
| WhiteIntel | what is wrong here? | 10:29 |
| lordievader | WhiteIntel: You don't have a connection? | 10:32 |
| lordievader | A network connection that is. | 10:33 |
| WhiteIntel | my server has a network connection and internet, thats the strange thing :\ | 10:33 |
| lordievader | WhiteIntel: The client throws the error? | 10:35 |
| WhiteIntel | yes thats from the client log | 10:36 |
| lordievader | WhiteIntel: So the client has no network connection. | 10:36 |
| WhiteIntel | the client has network connection, I´m connected over ssh to the client and I can ping google from the client | 10:37 |
| lordievader | WhiteIntel: On the client what is the output of "ip route"? | 10:38 |
| lordievader | !paste | WinstonSmith | 10:38 |

| WhiteIntel | http://paste.ubuntu.com/8717757/ | 10:39 |
| WhiteIntel | this is the output | 10:39 |
| lordievader | Seems okay, strange interface but whatever. What ip are you trying to reach? | 10:40 |
| WhiteIntel | a public ip of my VPN server | 10:40 |
| WhiteIntel | under my windows client (that is in the same network as the ubuntu one) I can connect without any problems | 10:41 |
| lordievader | WhiteIntel: Just to be sure, what is the output of "ip a s"? | 10:41 |
| WhiteIntel | http://paste.ubuntu.com/8717792/ | 10:45 |
| lordievader | WhiteIntel: Hmm, yes that should work. | 10:48 |
| lordievader | WhiteIntel: You mentioned vpn does this error happen after you enable the vpn? | 10:49 |
| WhiteIntel | yes after the command "openvpn --config vpn.ovpn" | 10:49 |
| lordievader | WhiteIntel: Ah, take a look at how it modifies your routes. It is probably the culprit. | 10:51 |
| WhiteIntel | do mean in the server config? | 10:51 |
| lordievader | WhiteIntel: What openvpn does is modify routes in order to throw (all) traffic over the vpn tunnel. Seems like this is misconfigured. | 10:53 |
| WhiteIntel | lordievader: the server is running in tap mode, as I said on a windows client this works very well and on the server I had this additional configs http://paste.ubuntu.com/8717920/ | 10:55 |
| lordievader | WhiteIntel: Run the openvpn on the client, and get the output of "ip route" and "ip a s" again. | 10:58 |

| lordievader | WhiteIntel: You don't have a default gateway anymore. | 11:06 |
| WhiteIntel | yea I saw that, but I don´t know why^^ | 11:06 |
| lordievader | WhiteIntel: Because openvpn messes up your routes. Check its config. | 11:07 |
| WhiteIntel | lordievader: my client config is this: http://paste.ubuntu.com/8718022/ | 11:08 |
| lordievader | WhiteIntel: I've never setup an openvpn vpn, so I do not know what can be wrong with the config. | 11:09 |

| WhiteIntel | lordievader: what else could be the problem? | 11:53 |
| lordievader | WhiteIntel: What do you mean? | 11:53 |
| WhiteIntel | lordievader: The reason why I can´t connect :\ | 11:54 |
| lordievader | WhiteIntel: I've already told you, openvpn breaks your routes. | 11:54 |
| WhiteIntel | lordievader: but why only under ubuntu? with my other clients all is working well | 11:55 |
| lordievader | WhiteIntel: Do the other clients run under the exact same conditions? | 11:56 |

| lordievader | o/ | 12:15 |
| elias_ | i have nginx 1.4.6 (ubuntu) and latest version is 1.7.6 is that secure and include all latest patchs | 12:16 |
| elias_ | or to be more secure its better to install latest version from source code ? | 12:16 |
| lordievader | !info nginx utopic | 12:18 |

| elias_ | lordievader, what do you mean by that :-/ ? | 12:18 |
| lordievader | Nothing was just wondering what version Utopic has. | 12:19 |
| elias_ | nginx -v tells me that i have 1.4.5 | 12:19 |
| lordievader | !info nginx trusty | 12:20 |

| elias_ | does it include all patchs ? | 12:21 |
| lordievader | elias_: 1.4.6 is available for Trusty ;) | 12:21 |
| lordievader | elias_: No idea, read the changelogs. | 12:21 |

| caliculk | Hello, I have a bit of a weird issue. Usually, after about 11 days or so, my server stops responding to network connections, yet it is still running. I can't really figure out why. I don't see anything abnormal in the kernel.log, dmesg.log, or syslog files. I was wondering what other steps I could take to diagnose the issue if it was software. My only ability is to connecto remotely to diagnose it, so I am really hoping it is a software | 16:51 |
| caliculk | issue and not a hardware one. | 16:51 |
| genii | caliculk: Perhaps check with lshw -C network what make and model the NICs are and what driver is claiming them, and then look up the driver to see if there's some known issue like this and a fix | 16:59 |
| caliculk | genii, thank you, will do right now. Is there anything that I could run continuously to double check if the nic is up or responding to connectivity, and if it fails, run specific commands that output to a file as well? | 17:00 |
| caliculk | Though from the first google search, there is a report of the driver/devices flat out not working, but that was from ~March's mailing list, and a September forum post. I would assume the latest kernel would have the most up to date driver as well, would it not? If not, I will just go download. | 17:03 |
| genii | caliculk: Conceivably maybe a shell script to see if it can ping an external box and if not then maybe to dump last 25-50 lines of dmesg and modprobe -r driver/modprobe driver, call it as a cron job on some reasonable schedule | 17:04 |
| genii | lunch, sort of afk gorging :) | 17:04 |
| caliculk | No worries, thank you for your help. :) Its frustrating enough for me being on a 7 hour time difference from the box, and when it goes down, I have to wait for someone to wake up to reset it. | 17:04 |
| caliculk | At least now I am getting a little help. :P | 17:05 |
| genii | caliculk: I know that there are some Broadcom NIC with an issue like this but don't recall the model number offhand | 17:06 |
| caliculk | This is unfortunately an Intel NIC, e1000e driver. So completely different manufacturer. | 17:06 |
| genii | caliculk: I recall there was some issue with that one. I'd have to look back into it, but something like they modified the e100 driver but doesn't always work properly | 17:22 |
| genii | caliculk: According to Intel at http://www.intel.com/support/network/sb/cs-032514.htm "The e1000e driver supports PCI Express* Gigabit Network Connections except the 82575, 82576, 82580, and I350." ... is one of these? | 17:29 |
| caliculk | I have an 82574L | 17:30 |
| caliculk | So, no. | 17:30 |
| genii | caliculk: Some of the things you might want to do in the cronjob besides dump the end of dmesg is check the current adapter settings with ethtool, , maybe also some traffic with wireshark, maybe tcpdump | 17:35 |
| genii | ethtool results when it goes down can be compared to what it reports when working normally, traffic analysis might show what it's trying to do and what the responses/lack of response is | 17:37 |
| RoyK | caliculk: I guess it might work if you add its PCI ID to the driver. IIRC it should be possible to do that dynamically without recompiling the driver, but I don't remember how | 18:43 |
| caliculk | RoyK, It is working right now, I am using a bouncer to talk from that box. It just coincidentally fails after a random number of days (usually longer than 8). | 18:45 |
| dasjoe | Are you sure it's network-related? | 18:46 |
| RoyK | caliculk: how does it fail? | 18:46 |
| caliculk | I don't know, I am not able to really diagnose it. But, from what I can tell, the connection just dies with the software programs still running in the background that would use the network connection. For instance, two days ago, I got an e-mail from logwatch, shortly after (maybe 10 to 20 minutes) I went to go login to the machine through SSH, and it wasn't responding. Tried encrypted VNC, znc, ping, etc. Everything failed. | 18:47 |
| caliculk | It has happened on more than one occasion. | 18:48 |
