Hi. Does anyone use UsePrivilegedPort or have ssh(1) setuid, and if so for what use case? ssh(1) has had code in it to support installing setuid root since approximately forever, however OpenBSD has not shipped it in that configuration since 2002 (and I suspect these days no vendor does). As far as I can tell, all of the reasons for...

...nnection and then pass a connected file descriptor back to ssh(1). This allows the ProxyCommand to exit rather than staying around to transfer data.

I tried setting rhost and rhostrsa authentication to no in /etc/ssh/ssh_config. That didn't work. When I added "UsePrivilegedPorts no" to /etc/ssh/ssh_config, it gave me a syntax error. I tried using ssh -P hostname, which locked up on authenticating to host. Someone I know who uses openssh on an Alpha Linux host has the same problem, but the ports are different even for him (1024-65535). To get openssh to work on a S...

The openSSH ssh command appears to not use a source privileged port (no matter what the options/configs) if the target port isn't a privileged port. For example: ssh -p 22222 foo.ucla.edu would never try to connect from a privileged port. Even with useprivilegedport=yes. This disallows .shosts RSA host authentication without a password. This breaks compatability with ssh-1.2.27 and isn't documented anywhere except possibly in the source to the ssh_create_socket function in sshconnect.c: /* * If we are running as root and want to connect...

Hi, there is a tiny bug in readconf.c: options->use_privileged_port is always set to 0 regardless of whether -P is specified or not. This has the effect that RhostsAuthentication is disabled even if "RhostsAuthentication yes" is specified. The (trivial) patch is appended below.

Hi there, I have a need to have scp pass the -P option to ssh to "bypass" the packetfilters that doesn't allow connections to return to arbitary "priviledged" ports, ie. ports <1024.

...nSSH's readconf.c broke many ~/.ssh/config files. Actually those which uses more than one whitespace character to separate keyword and value.

And now I got errors like this: | /u/rse/.ssh/config line 1: Missing yes/no argument.

Apologies if this is a FAQ; I couldn't find an answer on openssh.com or the mailing list archive.... Commercial SSH (I looked at 1.2.30) allocates privileged ports by counting /downwards/ from 1023, so that it will obtain a socket with (roughly speaking) the highest available privileged port number. This also appears to be the behaviour of rsh et al: (from sshconnect.c; whitespace elided)

Hi, and another feature request that I got from a debian user and that I think should be included in openssh. Thanks. |Unlike the 'old' ssh (Package: ssh; Version: 1.2.26-1.2)'s scp |openssh's scp does not support the -L option which according to |old ssh's manpage does the following: |> -L Use non privileged port.

Anyone, HELP!!!!!!!!!!!!!! I currently installed openssh-2.9p2 on SunOS 5.7 and 5.8. From the very moment that start to ssh out I get "Rhosts Authentication disabled ;the originating ip will not be trusted". I 've put "Useprivileged yes " in the ssh_config file, but then the ssh complains that there is a bad config line. Can some one tell me what is going on and how can I
