problem with lib/util_sock.c

[Cuyler Dingwell]

I get the following errors in the smb.log file.  If anyone has any ideas
about this please let me know.

[2001/05/01 09:51:46, 0] lib/util_sock.c:set_socket_options(154)
  Failed to set socket option TCP_NODELAY (Error Connection reset by
peer)

Error was
 Undefined error: 0

The samba hosts name is defined in the /etc/hosts file.

The system that samba is on is a FreeBSD (4.1) firewall.  It has a few
rules that I'm not sure my cause the above errors
00050 0 0 divert 8668 ip from any to any via dc0
00100 0 0 allow ip from any to any via lo0
00200 0 0 deny ip from any to 127.0.0.0/8
65000 0 0 allow ip from any to any
65535 0 0 deny ip from any to any

Thank you.
