Dear list, 
    There are two Ethernet Cards on our login node, one outside connection(202.122.*.*), one for inside connection to other servers.  The problem is Lustre sometimes confuse with configuration. 
[root at lxslc09 ~]# netstat -an | grep 988
tcp        0      0 0.0.0.0:988                 0.0.0.0:*                   LISTEN      
tcp        0      0 202.122.**.**:1022          192.168.50.32:988           ESTABLISHED

It connect mds with outside NIC, while oss with inside NIC. How to  bind Lustre on NIC(192.168.51.131),which is eth2 on this manchine. I have tried to add 
options lnet network=tcp(eth2)      to /etc/modprobe.conf
however, it doesn't work.
