Hello,
I am trying to connect a 2nd Linux machine to my Samba PDC using
smbmount. Both machines run Samba 3.0.14a. However, when trying to mount
using
machine2# /usr/local/samba/bin/smbmount //pdc/wpkg /raid/samba/mount -o
username=abc,password=123
it takes some seconds and then only brings up an I/O error. The log on
the primary machine brings up
[2005/07/19 10:28:36, 1, effective(1008, 1008), real(1008, 0)]
smbd/service.c:make_connection_snum(642)

Anyone knows what this is? Disabling server signing helps, but I guess
this is not a good security setting...
Thanks
Florian
