CommonProblems

We currently migrate to MediaWiki from our old installation, but not all content has been migrated yet. Take a look at the Wiki Team page for instructions how to help or browse through our new wiki at wiki.linux-vserver.org to find the information already migrated.

This page contains common errors and misconfiguration.

• Q: Try to connect to a vserver from the master or another vserver on the same host fails with

strace shows:

sin_addr=inet_addr("xx.xx.xx.xx")}, yy) = -1 EINVAL (Invalid argument)

• A: The vserver/master cannot communicate with another vserver on same host.

1. check all netmasks on all interfaces (do they overlap) ?
2. check policy routing (disable it temporary) ?
3. check that lo is up (Networking within a host/vserver always uses lo interface)
