I mount a remote directory to local point.

$mount -t smbfs //10.10.10.10/share /opt -o uname=foo,password=foo

But console tell me two error:
1857: session request to 10.10.10.10 failed (Called name not present)
1857: session request to 10 failed (Called name not present)

And sometimes mount sh didn't return like it has been blocked.

I use RH9.0 OS.

Please help me
Thanks!

try mount with netbios name :

mount -t smbfs //hostname/share /mnt/x

Thank you very much. Using netbios name can remove error message,
If not add password option, that is ok. But I need to write it to a script , so I must add password option. The blocking problem still be there.
I add debug option such as below
$mount -t smbfs //hostname/share /mnt/x -o uname=foo,password=foo,debug=4
The debug message is :
mount.smbfs started (version 2.2.7a)
added interface ip=10.190.7.38 bcast=10.190.255.255 nmask=255.255.0.0

Connecting to 10.190.5.29 at port 139
1906: session request ok
1906: session setup ok
1906: tconx ok

Then it not return , blocking there. Why?
I try it on RH7.3 , there are no this problem.
