I'm using the samba 2.0.6 rpm's from rawhide (2.0.6-9) - I modified the .spec to remove the --with-mmap and added syslog support (and put smbspool into the system) I get these errors in my logs: smbd[3713]: getpeername failed. Error was Bad file descriptor smbd[3713]: getpeername failed. Error was Bad file descriptor smbd[3713]: getpeername failed. Error was Bad file descriptor as far as I can tell they coincide with failed login attempts by NT 4.0 clients. I have applied the plaintext reg patches to the nt machines (all running sp5) In addition smbd will stop taking connections/die at different times of the day. I've had to turn on a monitor and restart script to deal with this problem. It restarts about 1-2 times a day. under [global] socket options = TCP_NODELAY SO_RCVBUF=4096 SO_SNDBUF=4096 os level = 65 Any suggestions? -sv
