...2.2.0p1 Keywords: setsockopt keepalive hang masquerade Symptom: For protocol 2, socket options (especially keepalive) are not being properly set for OpenSSH_2.2.0p1 (Redhat 7.0 distribution). I believe this to be a general problem that is not specific to the portable version of OpenSSH. Function packet_set_interactive is intended to be called to set socket options that are desired for interactive sessions. TCP keepalive messages are included in the socket options set, although they more properly ought to be elsewhere (as they are not related to interactivity). The problem: Function set_packet_set_interactiv...

Has anyone had any experience with ssh and DG/UX? I tried the ./configure and it could not determine the hosttype. After that problem was worked-arounded I get a LOT of warnings about declaring functions multiple times and then the compile fails with: packet.c: In function `packet_set_interactive': packet.c:803: `IPTOS_LOWDELAY' undeclared (first use this function) packet.c:803: (Each undeclared identifier is reported only once packet.c:803: for each function it appears in.) packet.c:815: `IPTOS_THROUGHPUT' undeclared (first use this function) suggestions would be nice but I...

...gin: Sat May 10 14:27:01 2003 from ip-66-80-53-59.d Sun Microsystems Inc. SunOS 5.8 Generic Patch October 2001 You have new mail. The "getsockopt TCP_NODELAY: Socket operation on non-socket" message is bogus. This appears to be an editing botch in the portable version of packet_set_interactive, as there's a missing "return;" statement compared to the OpenBSD version. Here is a proposed patch. =================================================================== RCS file: RCS/packet.c,v retrieving revision 3.6.1.2 retrieving revision 3.6.1.2.0.1 diff -pu -r3.6.1.2 -r3.6.1...

...s. If the ssh client is invoked with: ssh -N host -R port # TCP_NODELAY is not set ssh -n host -R port sleep 1d # TCP_NODELAY is set - this is a workaround There is a difference in TCP_NODELAY being set or not depending on whether there is a remote command being executed. This is because packet_set_interactive() is only called in do_exec() on the server side. This bug has the unfortunate effect of not setting TCP_NODELAY for port forwarding only connections. The proper fix is probably to use attachment 1099 by Darren Tucker that sets it for all connections on the server side. https://bugzilla.mindrot...

...Red Hat linux 8.0: When I ssh to a host with a proxy command, I get the following message: $ ssh tooth.toronto.redhat.com getsockopt TCP_NODELAY: Socket operation on non-socket Then things work normally. The problem seems to be that a "return;" has been deleted from the function "packet_set_interactive" in packet.c. The code reads: /* Only set socket options if using a socket. */ if (!packet_connection_is_on_socket()) if (interactive) set_nodelay(connection_in); The odd indentation suggests that something has gone wrong. The logic doens't make any sense, either: if the conne...
