Network mess

Discussion in 'Linux Networking' started by Lord Eldritch, Jun 23, 2012.

  1. We have a network with this nodes (among many more):

    192.168.4.100
    192.168.4.1
    192.168.4.151
    192.168.4.152 (router between VLANs)
    192.168.5.1
    192.168.4.220 (switch with VLANs)
    192.168.2.100
    192.168.0.100

    Provided I set the routes properly, I can access (ping, ssh):

    From 192.168.4.100 to 192.168.2.100
    From 192.168.4.100 to 192.168.0.100
    From 192.168.4.100 to 192.168.4.151

    But I can't:

    From 192.168.4.100 to 192.168.4.1
    From 192.168.4.100 to 192.168.5.1
    From 192.168.4.100 to 192.168.4.220
    From 192.168.4.100 to 192.168.4.151 (but I can from 192.168.4.152. Then from
    192.168.4.151 I can't connet to 192.168.4.100).

    Anyone has a hint or a tool to check what I'm missing?

    Thanks in advance.

    How many routed networks does that cover, and using what netmasks?
    Netmasks, routes, and VLANs. Check the netmasks first. But for us to help
    you with specifics, you'll need to provide a fair amount more information
    for each interface.

  4. Sorry to both of you. At the end it was a problem with the network
    interfaces I guess. We had a bond and my theory is was that one of the
    interface fell off the bond and resulted in one interface and one bond doing
    the same job (an probabably one missconfigured inside the bond).

    I solved it deleting all the interfaces and creaing them one by one,
    attaching them to the MAC.

    What puzzled me was the posssibility to ping some nodes of the network and
    without any problem to other networks (all going out through the bond) but
    missing it with some nodes in teh same network.
