|
|
Hi,
I made an upgrate on our server from kernel 2.6.31-gentoo-r10 to 3.5.7-gentoo.
Doing the upgrate I also needed to update all depencencies, finally I made emerge -uD world and revdep-rebuild. The system is consistent and all packages are recompiled without any problem.
I rebooted the machine. And everything started ok, without any problem.
The problems started a bit latter, basically the machine is on, and executing any tehing that was on it. But the machine is not allowing you to do new ssh connections, is not generating logs (but doing rc-status all services are on). For example you can not execute the who command, is not returning anything. And most of the times if you try to do emerge the console hangs.
Finally if you do halt, the console is frooze and you can do nothing, you can just do a hard halt.
Last things reported on the messages log, are not strange and never the same (syslog, new user entrance, ...).
Right now I don't know what else to check if anybody can help me, I will post any file needed.
Thaks. |

Nothing strange. Last log entrances are from yesterday at 23:10 and are con.info messages.
The machine is still on now. But there is no connection with ssh from the outside, also is not possible to use the command sudo, basically you do the sudo it asks for password and then it does nothing. If you try to enter with ssh you get this message:
ssh_exchange_identification: Connection closed by remote host |

That is a large version jump. Is it fair to assume that the system had gone for an extended period with no updates? What services did it offer to the outside world? Is there a possibility that it was compromised during the time when it was out of date? |

Tambor: maybe this is a silly question, but have you checked that you have space where /var is mounted? I understand that you see nothing in the server logs at all, and the things that you are trying are always attempting to log something.
Not sure if your file system has reserved space for these situations either.
Having said all this, I'd be suspicious about the system having been compromised with a very buggy unwanted piece of software.

gabrielg: Is not a problem on /var. This partition has 19G of free space.
hue: We updated the system and rebooted it with all the new software, kernel, ... to the outside we ofer ssh, nfs, postfix, samba. |

what fs is /var? if you are using a inode based fs, you can still have free space but run out of inodes. _________________ Only two things are infinite, the universe and human stupidity and I'm not sure about the former - Albert Einstein |

is a reiserfs file system.
Now I noticed that I can not create any file on /var, for exampe I try touch asdf and the console gets block.
Non of these problems appears just booting the machine, but in few hours or some days starts appearing. |

first check permissions, if the are ok, check /proc/mounts, maybe /var was remounted a ro.
if that is the case you may need to run reiserfs's check disk equivalent. _________________ Only two things are infinite, the universe and human stupidity and I'm not sure about the former - Albert Einstein |

This is the /proc/mounts for /var :
/dev/md3 /var reiserfs rw,nosuid,nodev,noatime 0 0
Permisions on /var :
drwxr-xr-x 16 root root 432 Oct 25 19:09 var
I'm trying to write the file as root. |

In fact there is no error, you get the console with no answer and waiting there.
Finally you should kill the process of "touch asdf" for example. |

I had some 'similar' problems with 3.5.X (gentoo-sources) - it has some network problems, it was 'visible' by logging to facebook - opera was saying about ssh failure, chromium was able to load half of page or so,
rest sites was ok ... also my favourite network game was crashing in the middle of game and unable to reconnect even after restart, first I reverted to 3.3.7 (zen), but some time ago I updated kernel to liquorix 3.5 (3.5.4 I think ) and everything is ok.
So just check if you can login to facebook and load whole page -> if not it's 100% some kernel problem _________________ Sent from Windows |

So... when you reboot the machine, are you still unable to write to /var, or does the inability to write to /var develop after a while?
I suspect that you have a lot of crons because they are waiting to write to /var, do you have anything out of the ordinary in your crontab?
I would have asked you to do a df -i /var before, but I really don't know if that applies to reiserfs. |

why are you using nodev,nosuid? any specific reason?
also, what is /dev/md3? raid? _________________ Only two things are infinite, the universe and human stupidity and I'm not sure about the former - Albert Einstein |

/dev/md3 is a softraid
for nodev and nosuid there is any specific reason. Is just a typical setup. |
