I am using SuSE 6.3 with Samba 2.0.6, and swat to configure samba. When I compile with Visual Studio on a samba share, I get very often a message "System could not write nack xyz.idb" and my network connection crashes. In the console I see the message "transmit timed out, switching to 10base-TX" and "transmit timed out, switching to 100base-TX" until I reboot. I am using a tulip card on a 100base network. I didnt see any interesting lines in log.smb, but its quite strange that there requests from other networkers because I set all name serving machanisms to off (second config) This problem also occurs when I unzip a lot of files, so I think it has something to with the traffic. It is very urgent to solve the problem, else I have to change to a nt server (aargh!). The network crashes about 2 times an hour. This one fails very often: [global] workgroup = myworkgroup netbios name = me server string = me encrypt passwords = Yes map to guest = Bad User unix password sync = Yes log level = 3 deadtime = 15 keepalive = 30 read prediction = Yes socket options = SO_KEEPALIVE TCP_NODELAY os level = 2 local master = No hosts allow = 194.136.121. 194.136.122. dos filetimes = Yes dos filetime resolution = Yes [homes] comment = My home is my castle read only = No create mask = 0750 directory mask = 0750 Second try: [global] workgroup = myworkgroup netbios name = me server string = me encrypt passwords = Yes map to guest = Bad User unix password sync = Yes log level = 3 nt smb support = No deadtime = 15 keepalive = 30 read prediction = Yes socket options = SO_KEEPALIVE TCP_NODELAY os level = 0 local master = No hosts allow = 194.136.121. 194.136.122. dos filetimes = Yes dos filetime resolution = Yes fake directory create times = Yes
