Hi OpenVZ-Community, Hi Christian,<br>
<br>
I noticed the same "problem" with the 2.6.32 kernels. Interestingly
it only seems to happen on my rpm-based Kernels from the
OpenVZ-Repo. The kernels I patched and compiled myself don't seem to
behave that way.<br>
Also, not all processes that open ports seem to be visible via
netstat on the hw-node. Here the difference in behaviour between
munin and apache2:<br>
<br>
[root@srv05 ~]# vzctl exec 512 "netstat -tulpen | grep 4949"<br>
tcp 0 0 0.0.0.0:4949 0.0.0.0:*
LISTEN 0 23963289 14168/munin-node<br>
[root@srv05 ~]# vzctl exec 510 "netstat -tulpen | grep 4949"<br>
tcp 0 0 0.0.0.0:4949 0.0.0.0:*
LISTEN 0 154512328 31520/munin-node<br>
[root@srv05 ~]# netstat -tulpen|grep 4949<br>
tcp 0 0 0.0.0.0:4949
0.0.0.0:* LISTEN 0 56159312
652391/munin-node<br>
[root@srv05 ~]# netstat -tulpen|grep :80<br>
tcp 0 0 0.0.0.0:80
0.0.0.0:* LISTEN 0 547379989
191426/apache2 <br>
tcp 0 0 :::80
:::* LISTEN 0 28979
10656/httpd <br>
<br>
I only use venet-based networking on all my nodes.<br>
<br>
