search for: so_keepalive

Hi! There are configuration knobs (TCPKeepAlive) to enable/disable the use of TCP keepalives both in the ssh client and server. Unfortunately some UNIX systems default to SO_KEEPALIVE=on and some to =off. This may even be settable on a per host basis (OpenBSD default net.inet.tcp.always_keepalive=1 ???). For the TCPKeepAlive configuration knob I would like to propose changes along the lines showed in the attached patch (there is perhaps more elegant ways to do this). The patch...

Hi there everyone, Again another slight thing I noticed since I upgraded to Samba 2.0.6 from 2.0.5a. I'm using RedHat Linux on a Celeron 400 with kernel 2.2.13. My socket options in smb.conf is set to "TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE SO_SNDBUF=8192 SO_RCVBUF=8192". However I've started getting the following everytime I SIGHUP to reload the configs and stop-start: [1999/11/15 12:02:41, 0] lib/util_sock.c:set_socket_options(148) Failed to set socket option SO_KEEPALIVE (Error Bad file descriptor) [1999/11/15 12:02:41...
