 OK, this isn't over yet :-)
 
 I just compiled and installed 2.6.8.1-vs1.9.3-rc2.1, with 
 util-vserver-0.30.195 on a freshly installed FC1 machine.
 
 Created a vserver, created a config (using the new utils method) when i 
 start it (with or without hide_netif in the flags file), the interface is 
 NOT created (ifconfig does not show it from either outside or inside), yet 
 I can ping the IP number and ssh to the vserver from outside.
 
 I noticed a listdevip tool in utils, it shows:
 
 # ./listdevip
 127.0.0.1/255.0.0.0
 192.168.1.105/255.255.255.0
 192.168.1.130/255.255.255.0
 
 The .130 address is the vserver.
 
 Is this normal?

yes ;) probably the missing piece you are looking
for is the 'alias' option, if you use that for an
ip assigned to a vserver, a named alias (e.g. eth0:0)
will be created for this IP, this alias will be
visible with ifconfig and will also be shown inside
the vserver (with ifconfig and friends), the 'default'
is to create just the IP (no alias) and this should
be showns inside and outside with 'ip addr show'

HTH,
Herbert

PS: 2.6.8.1-vs1.9.3-rc2.1 is a backport and it might
have some issues, so if you can not get this working
please keep buging me ;)

[Vserver] interfaces show ip addresses?

In vs 1.9.3 I noticed that ifconfig from within a vserver shows the inet 
addr of eth0 and lo (in 1.2x it did not) - is this the way it's supposed 
to be, or am I missing a configuration option of some kind?

Re: [Vserver] interfaces show ip addresses?

2004-10-06 Thread Gregory (Grisha) Trubetskoy 
Strange... after a reboot it behaves differently - pretty much gives me 
what I need - hide the IP of eth0, but show the vserver IP. Before it 
would hide all interfaces sompletely. Not sure what happened there...

it is supposed to be so, and you are probably looking
for VXF_HIDE_NETIF ...
But this appears to be hiding all interfaces, so that ifconfig shows nothing 
at all?

What can I do to get it to behave more like 1.2x, where it shows the IP 
address of the vserver but not much else ?

TIA,
Grisha

OK, this isn't over yet :-)
I just compiled and installed 2.6.8.1-vs1.9.3-rc2.1, with 
util-vserver-0.30.195 on a freshly installed FC1 machine.

Created a vserver, created a config (using the new utils method) when i 
start it (with or without hide_netif in the flags file), the interface is 
NOT created (ifconfig does not show it from either outside or inside), yet 
I can ping the IP number and ssh to the vserver from outside.

I noticed a listdevip tool in utils, it shows:
# ./listdevip

Is this normal?
