hmm a bug?

so save some more money, by utilizing more, free resources?
a nightmare? maybe stop dreaming?

what exactly did you patch? (if you patched at all)

can you give an example? and include the errors?

is it necessary to assign the IPs manually?
the vserver tools usually assign the IPs at server start/stop

I think this wasn't reproducible or simply was not reproduced.

again v_xxx scripts are used in the main server to
prevent services/daemons from binding to ALL possible
addresses (thereby making any further bind within any
virtual server impossible)
the NEW (read version 0.19) tools/scripts honor the
multiple IP feature for any v_xxx service, the OLD
(read version 0.18) scripts didn't ...
my workaraound for 0.18 was (for example for v_sshd)
# chkconfig: - 55 25
# description: Wrapper to start sshd bound to multiple IPs
if [ -f /etc/vservices/sshd.conf ] ; then
IPC=`for n in $IP; do echo "--ip $n"; done`
exec /usr/sbin/chbind $IPC /etc/init.d/sshd $*

so this binding fails?

inetd or identd? or identd over inetd?
anyway you have some bug in your script or configuration.
> Anyone can send me an exemple of configuration file plz
you can use the given example, or just the chbind tool
to further reduce the used addresses (subset of the addresses
assigned to the vserver)
