[olug] Networking issue

[Jay Swackhamer]

It sounds like the typical. "I bought an application, here, you make  
it work like I want it to, and it's your fault when it's broken."

I have worked with a few. The last one was the 'Goldmine'  
email/contact/sales app. It's setup the same way as you described  
yours. It would regularly crash when it was shared from a windows  
machine, and still crashed when I initially moved it to a samba share.

It ran reliably with 5-10 users on a samba share from a linux box with  
the following config.

In the Global conf section in smb.conf

         #socket options = TCP_NODELAY  SO_SNDBUF=2920
         socket options = TCP_NODELAY  SO_SNDBUF=5840
         #socket options = TCP_NODELAY  SO_SNDBUF=8760
         #socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192


[apps]
         comment = Goldmine
         path = /opt/apps
         ;path = /opt/goldmine
         ;path = /mnt/new_sys/opt/goldmine
         writeable = Yes
         guest only = Yes
         guest ok = Yes
         create mask = 0777
         force create mode = 0777
         directory mask = 0777
         force directory mode = 0777
         hide dot files = No
         share modes = No
         fstype = SAMBA
         oplocks = no
         level2 oplocks = no
         strict locking = no
