similar to: Equivalent ssh_config setting for "ssh -N"

Oops. That's -T. From the man page, it doesn't really look like there's an ssh_config option for -N. -----Original Message----- From: openssh-unix-dev [mailto:openssh-unix-dev-bounces+scott_n=xypro.com at mindrot.org] On Behalf Of Scott Neugroschl Sent: Tuesday, August 09, 2016 1:04 PM To: Volker Diels-Grabsch; openssh-unix-dev at mindrot.org Subject: RE: Equivalent ssh_config

Dear OpenSSH developers, I hope you don't mind that I resubmit my patch for OpenSSH. This patch adds a new ssh_config option "ExecRemoteCommand", which is the missing equivalent to the "-N" command line option. For implementation notes, please have a look at the top of the patch. Regards, Volker -- Volker Diels-Grabsch ----<<<((()))>>>----

Hi everyone, I know scp is kind of the red-headed stepchild of the suite, but I'd like to propose an extension to the syntax for remote-remote passthrough using the "-3" option. Currently the syntax is essentially scp -3 [ -P port ] [user@]host1:file [user@]host2:file This is great, as long as both remotes are on the same port. It causes difficulties if host1 and host2 are not

Build of 5.1p1 fails on SCO OSR6 with the error: UX:acomp: ERROR: "addrmatch.c", line 100: undefined struct/union member: sin6_scope_id configure checks for presence of struct sockaddr_in6 and uses the system declaration if found (via #define HAVE_STRUCT_SOCKADDR_IN6 in config.h) If not found, the struct is declared in openbsd-compat/fake-rfc2553.h. OSR6 has struct sockaddr_in6 but it

Why is there an inconsistency with the option for the destionation port. ssh -p <port> ... scp -P <port> ... sftp -P <port> ... For scp it is neccessary to be "-P" ( Quote: " Note that this option is written with a capital 'P', because $B!](Bp is already reserved for preserving the times and modes of the file in rcp(1)." ). Also sftp uses already

I'm running a 5.0p1 derivative SSH server (that for various reasons I can not upgrade), on a host system that does not support PTYs. Attempts to connect to that sshd via sftp are failing due to an inability to allocate a pty. I can't really see a reason that an sftp session requires a pty. Is this addressed in later versions? Should I patch my system to avoid even trying to

I'm seeing something similar to bug 1179 (https://bugzilla.mindrot.org/show_bug.cgi?id=1179), even with the reordered IP options check. For some reason, getsockopt is returning an IP options of length 2, value 00 00. Would Mark Weindling's original patch (https://bugzilla.mindrot.org/attachment.cgi?id=1105) break anything if I incorporated it? Platform: HP NonStop S7000 series

A couple of notes about mget/mput in SFTP (5.1p1). 1. They aren't documented in the SFTP man page 2 They misbehave -- "mput a.txt b.txt" copies a.txt to b.txt on the server "mput *.txt b.txt" copies the first wildcard match to b.txt on the server "mput a.txt b.txt c.txt" copies a.txt to b.txt on the server "mput a.txt

I'm using 5.0p1 (Yeah, yeah. I know.). For various reasons, I am unable to upgrade to the latest and greatest, which probably would solve my problem. Here's my question. When doing an scp from remote to local (e.g.: scp user at host:remote localfile), is there any way to specify the path to the remote scp? Or do I have to patch the code to allow it? ---- Scott

I read an article today about keyboard interactive auth allowing bruteforcing. I'm afraid I have minimal understanding of what keyboard-interactive really does. What does it do, and should I have my clients set it to off in sshd_config? --- Scott Neugroschl | XYPRO Technology Corporation 4100 Guardian Street | Suite 100 |Simi Valley, CA 93063 | Phone 805 583-2874|Fax 805 583-0124 |

I see that support for AuthorizedKeysCommand has been added. The arguments supplied to the command is just the authenticating user. Can we add the SSH connection details (ie. source and destination IPs and ports) as well? This command seems to be the idea way of requiring one set of credentials from inside an organisation (say the user's own authorized_keys file) and another set from outside

I'm working from modified 5.0p1 codebase. What I'm looking for is a mechanism to limit the number of simultaneous connections on a per-user/IP basis. That is, disallow multiple simultaneous logins/authentication of the same user from different IP addresses. e.g.: fred from 10.1.1.1 - accept fred from 10.1.1.2 -- reject while fred is still connected from 10.1.1.1 fred from 10.1.1.1 - OK

I've noticed a bug with even recent OpenSSH products, where if the host disconnects during a certain period of time, the connection becomes frozen causing possible expolit problems . For example [root at portal ~] users root [root at portal ~] uptime -u (used to show how many users the box believes is logged on) 2 Users [root at portal ~] In theory this trapped connection can and has

I haven't been keeping up with the internals, I'm afraid. Does OpenSSH have support for Port Knocking? I might be interested in looking into that, as a way of reacquainting myself with the current code base. --- Scott Neugroschl | XYPRO Technology Corporation 4100 Guardian Street | Suite 100 |Simi Valley, CA 93063 | Phone 805 583-2874|Fax 805 583-0124 |

On Solaris 10 (SPARC & x86), I'm seeing the following error: error: Failed to allocate internet-domain X11 display socket.
