[jira] [Commented] (SSHD-863) Add local/remote port forwarding to/from Unix sockets
[ https://issues.apache.org/jira/browse/SSHD-863?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16691669#comment-16691669 ] Goldstein Lyor commented on SSHD-863: - Indeed it seems like something that can be done (as a *separate* module - e.g., _sshd-openssh-fwd_). However, I don't see it happening any time soon unless someone that is *not* part of the SSHD project takes it upon him/herself to contribute this code (including unit tests). The other way this can happen is this feature becomes very popular - and even then, my instinct tells me that we would need to rely on the *community* to contribute the code. > Add local/remote port forwarding to/from Unix sockets > - > > Key: SSHD-863 > URL: https://issues.apache.org/jira/browse/SSHD-863 > Project: MINA SSHD > Issue Type: Improvement >Affects Versions: 2.1.0 >Reporter: Björn Kautler >Assignee: Goldstein Lyor >Priority: Minor > Labels: future, wishlist > > Would be nice if MINA SSHD also supports forwarding sockets, not only ports. > Currently you can only forward from port to port, but SSH now can do from > port to socket, from socket to port, from port to port and from port to > socket. -- This message was sent by Atlassian JIRA (v7.6.3#76005)

[ https://issues.apache.org/jira/browse/SSHD-863?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16690936#comment-16690936 ] Björn Kautler commented on SSHD-863: I had a quick look at the specs and it is actually not past of the standard SSH protocol, but an OpenSSH extension. You can find its technical description at point 2.4 of https://cvsweb.openbsd.org/src/usr.bin/ssh/PROTOCOL?rev=HEAD. As far as I have seen it basically follows the same rules and flow as normal port forwarding, just with slightly different protocol messages. > Add local/remote port forwarding to/from Unix sockets > - > > Key: SSHD-863 > URL: https://issues.apache.org/jira/browse/SSHD-863 > Project: MINA SSHD > Issue Type: Improvement >Affects Versions: 2.1.0 >Reporter: Björn Kautler >Assignee: Goldstein Lyor >Priority: Minor > > Would be nice if MINA SSHD also supports forwarding sockets, not only ports. > Currently you can only forward from port to port, but SSH now can do from > port to socket, from socket to port, from port to port and from port to > socket. -- This message was sent by Atlassian JIRA (v7.6.3#76005)

Björn Kautler commented on SSHD-863:
Sure, I understand of course, thanks for looking into it.
In the meantime I worked around it with {{Runtime#exec()}} and require {{ssh}}
to be present, but that is suboptimal of course. :D

And for the local socket there are multiple libraries available, but I have no experience with them. For example https://github.com/jnr/jnr-unixsocket or https://github.com/mcfunley/juds or https://github.com/kohlschutter/junixsocket. The latter maybe looks best from description as it is ASL licensed and uses Java sockets API while the others seem not to. > Add local/remote port forwarding to/from Unix sockets > - > > Key: SSHD-863 > URL: https://issues.apache.org/jira/browse/SSHD-863 > Project: MINA SSHD > Issue Type: Improvement >Affects Versions: 2.1.0 >Reporter: Björn Kautler >Priority: Minor > > Would be nice if MINA SSHD also supports forwarding sockets, not only ports. > Currently you can only forward from port to port, but SSH now can do from > port to socket, from socket to port, from port to port and from port to > socket. -- This message was sent by Atlassian JIRA (v7.6.3#76005)

For documentation for example look at the ssh man page at
https://man.openbsd.org/ssh. The description of the -L and -R options.

We support the IP local/remote port forwarding in full - both on server and
client. As far as _Unix_ sockets are concerned, there is no available Java
library that I am aware of that provides this service since it involves
*native* code. If you can recommend a good framework for it then we can think
about this issue. However, since the feature is not in great demand (thus
marked it as _Minor_), you might want to consider adding such support yourself
(see _sshd-contrib_ package) - with some help from us. It can be a good
exercise in using SSHD library as well as a welcome contribution. If it does
become very popular we may consider adding support for it - again, depending on
the availability of some 3rd party library that can provide this kind of
support.
