[Vserver] Adding IPs without restarting the vserver
I'm running vservers on SuSE with Kernel 2.6.x and utils 0.30.207 1. How can i add an ip-address to an running vserver without restart? 2. My VServer Master hat 2 Interfaces eth0 and eth1, eth0 for the vserver and eth1 for backups, with an extra gateway. How can i use this gateway inside a vserver without adding an ip for each vserver? Normally all ip-requests has the source ip added by chbind command.

Change content of file 'dev' to 'eth1' and add another file in same directory

Betreff: [Vserver] VServer utils vlan interface problem
Heyaz,
I am trying to migrate to the new configuration method of util-vserver
(0.30.196) and have come across the following problem:
* vlan support is either broken, or changed in a way I am unable to understand
(very probable as this is my first go at the new configuration method); an
example: I create /etc/vservers/${SVRNAME}/interfaces/0/dev containing
'eth1.4000'.
When I start ${SVRNAME} using vserver ${SVRNAME} start; it gives me the
following output:
ERROR: trying to add VLAN #0 to IF -:eth1 4000:- error: Invalid argument
Cannot find device eth1.4000
SIOCGIFFLAGS: No such device
Cannot find device eth1.4000
SIOCGIFFLAGS: No such device
On a side note (no pun intended); why moving from a single file configuration
to a configuration tree ? In my opinion this will make things more complicated
than needed: A config file with comments containing examples say a thousand
words and give the user a head start with his first install. The configuration
tree (without examples) will cause for a steep learning curve; it takes time to
find your way around the tree.
If the idea is to put the configuration tree into a database I'm all for it,
but ATM I can't see how the move will simplify things for the average vserver
admin.
Regards,
Dennis

AW: [Vserver] Routing Problem with VServer Kernel
I found the reason / solution of this problem ! I started the sshd with v_sshd wrapper. The chbind bound the sshd and all subprocesses to my ipv4root on eth0, so requests via eth1 interface fails. I configured /etc/ssh/sshd_config to listen only on one address and didn't use v_sshd, now everything works fine. regards Holger -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Gesendet: Freitag, 21.
