These patches implement a new mux client request to list the currently opened TCP forwardings. It also removes some todos regarding keeping the list of forwardings in the options up-to-date.

For systems where the local hostname is obtained as a short name without domain, there should be a ssh_config option "DefaultDomain" as in ssh-3.x from ssh.com. For the server, there might be a corresponding option in order to strip the domain name from the remote client name (if it matches the server's DefaultDomain) for use in auth_rhost2, since netgroups usually contain short

I'd like a feature whereby ssh puts itself in the background after the first successful X11 (or other port) forwarding. The reason for this is simple: error handling. If the application fails to open the X display and exits, then the client can still exit with the application's exit code. But if the application opens the X display successfully, then it can just display any errors by

In the changelog, there is an entry: 20001129 - (djm) Back out all the serverloop.c hacks. sshd will now hang again if there are background children with open fds. Does this mean that this is regarded as expected (and correct) behavior, that should not change in the future, or does it mean that this behavior is a known problem that someone will eventually fix? --Adam -- Adam McKenna
