    Hi all,

    For some reason (I think some eth0 network problem) my server is sometimes not accessible anymore for some hrs! (it does fix itself (sometimes))

    1st I thought that it was some programe running on a cron job, but now (with help of Munin) I think I found the problem.

    When the server is not accessible anymore Munin is logging eth0 errors (see image)

    [​IMG]

    This is how eth0 looks normal

    [​IMG]

    The server is using Fedora RC4 with ISPconfig, and the Firewall that comes with ISPconfig.

    Anyone here who might know what could cause this eth0 error, and how I can fix it?

    Any errors in the logs?

    Hi falko,

    I've had a look at the logs, but did not see anything special! (lot's of info, so I might have missed it)

    Also.. I'm not sure what log to look at! Is there a log that is logging all the eth0 data?

    I really need to get this fixed a.s.a.p as sometimes the server will work again after some time, and sometimes it does not..
    As I'm off to the US over 1 week (for 3 weeks) I can not reset the server by hand :/

    Does your kernel use the correct driver for your network card? What kind of network card is it (model)?
    Do you see errors related to eth0 when you run
    Code:
    dmesg
    ?

    The server is a Dell PowerEdge SG1425.

    the NIC is/are
    (2 x Intel Corporation 82541GI/PI Gigabit Ethernet Controller (rev 05))
    note: I'm only using one NIC

    Looks ok. I saw some output of SELinux. Is SELinux disabled?

    Hmm it should be disabled, but I do also see
    I guess that this is saying that SELinux is running. I have NO CLUE how it got installed!

    The install I did was the "perfect_setup_fedora_core_4", and I'm 100% sure that I disabled the SELinux option!

    Is there an easy way to 'kill' it again?

    Anyway... I've now made a small bash script that I run every hr to ping the gateway.. If no ping.. restart the network :/

    Code:
    #!/bin/bash
    
    pingAddress="10.0.0.138"	# IP of gateway
    emailAddress="root@host"	# address to send restart message
    timeNow=$(date)			# set the date and time
    
    if [ -n "$(ping -c 1 $pingAddress|grep 100%)" ]
    then
    # no ping reply.. Lets email root and restart the network :-(
        mail -s "No ping. Server network restart" $emailAddress <<-END
        This is to inform you that the server network was restarted at $timeNow
    END
    /etc/init.d/network restart
    fi

    Hey I'm having a similar problem - I followed the perfect Debian sarge install.
    Basically the server is fine... most of the time, but it goes down for periods of time where nothing will work - when trying to connect to websites it just times out. It wont' reply to pings, and email services are down.

    This is my dmesg output related to the ethernet.

    ~# dmesg | grep e100
    BIOS-e820: 00000000fee00000 - 00000000fee10000 (reserved)
    e100: selftest OK.
    e100: eth0: Intel(R) PRO/100 Network Connection
    e100: selftest OK.
    e100: eth1: Intel(R) PRO/100 Network Connection
    e100: eth1 NIC Link is Up 100 Mbps Full duplex

    I'm not really sure why this is happening. Have you found anything yet?

    My server got exactly the same symptoms.. I think that (in my case) it is something with the network (eth0) or firewall, as when I look at any other running service logfile (when the server is 'online again') I do not see any problems.

    I remeber when I was installing the server some time ago I 'kind of' had the same problem.

    The terminal (even when it was sitting at the login screen asking for a login) sometimes showed
    When it did show this, the network went down, and the only way to access the server was by direct access on the system.. A pain in the neck now as the server is about 1hr away from me :/

    Again thesquib, I'm here talking about my server. I'm not sure if this is also the problem with your server!

    You can disable SELinux in /etc/selinux/config. You must reboot your server afterwards.

    That's the normal message when iptables goes up. Maybe it's some kind of firewall rule that blocks networking.

    This is what it is set to (I did not change it)
    Code:
      GNU nano 1.3.5-cvs             File: config
    
    # This file controls the state of SELinux on the system.
    # SELINUX= can take one of these three values:
    #       enforcing - SELinux security policy is enforced.
    #       permissive - SELinux prints warnings instead of enforcing.
    #       disabled - SELinux is fully disabled.
    SELINUX=disabled
    # SELINUXTYPE= type of policy in use. Possible values are:
    #       targeted - Only targeted network daemons are protected.
    #       strict - Full SELinux protection.
    SELINUXTYPE=targeted
    
    It looks like it's set to: disabled allready!

    Okay, but is it also normal that it's showing it over and over and over again?
    Even when I'm not logged in (terminal is sitting at the login: prompt)

    More strange info about SELinux.

    uname -a

    So NO SELinux kernel....

    When I run 'cat /proc/1/environ' I get this:

    Mine must be some sort of firewall... I just managed to figure out that even though services are not available - I can actually use everything fine on another server on the same ip range. Yet the internal network and the external network has intermittant access..

    I haven't configured a firewall, but I did enable it once or twice within the ispconfig system

    That's good.


    Yes, that's normal.

    Are you sure no other firewall was running when you started the ISPConfig firewall? If another one was running, both firewall will interfere with each other and produe unforeseeable results.
    Please disable the ISPConfig firewall, then reboot the system and then post the output of
    Code:
    iptables -L

    falko, I really appreciate you helping me with this problem..

    This is what I get after disabling the ISP's firewall and a reboot, and no I'm not using any other firewall with the ISP one.

    Code:
    [root@host ~]# iptables -L
    Chain FORWARD (policy ACCEPT)
    target     prot opt source               destination
    
    Chain INPUT (policy ACCEPT)
    target     prot opt source               destination
    
    Chain OUTPUT (policy ACCEPT)
    target     prot opt source               destination
    [root@host ~]#

    Reading a lot about 'sk98lin' and Gigabit Lan, and network problems.. Not sure if I'm using this with my Fedora RC4 server, but when I do a 'locate sk98lin' I do get a lot of files back!

    Could this be causing the problems?
     
  20. falko

    falko Super Moderator ISPConfig Developer

    At least it's possible.
    Do you get the same problems if you leave the firewall off? That would mean it isn't caused by the firewall.
