I have configured SSH to be on port 20000. When I try:

svn co svn+ssh://server.com:20000/home/svn/proj1 proj1 --username jm

I get

svn: To better debug SSH connection problems, remove the -q option
from 'ssh' in the [tunnels] section of your Subversion configuration
file. svn: Network connection closed unexpectedly

I think I need to tell SVN to use port 20000 also?

I am on Ubuntu 11.10


You can define a new 'tunnel' in your Subversion configuration (~/.subversion/config). Find the section [tunnels] there and define something like:

foo = ssh -p 20000

Afterwards you can contact your repository via the URL svn+foo://server.com/home/svn/proj1 proj1.

  • Also, if you want to override the default svn+ssh protocol's port, just define ssh = ssh -p 20000. This assumes you've modified /etc/ssh/sshd_config on the server so that Port 22 is replaced with Port 20000. – Cloud Sep 29 '13 at 18:01

    @Dogbert: it doesn't work like you say: I tried ssh = ssh -p 20000 and then tried to checkout svn+ssh://example.org/var/svn-repos/mydev/trunk but this still tries on port 22 – rubo77 Jan 26 '15 at 16:15

Whenever you need to access an ssh server on a non-default port or with a different user name, you can define an alias in ~/.ssh/config.

Host mysvn
HostName server.com
Port 20000
User jm

Then run svn co svn+ssh://mysvn/home/svn/proj1.


If for some reason you could not edit the ~/.subversion/config file, then you can specify the port in the command-line:

svn co svn+ssh://joe@myserver/myrepo/ --config-option="config:tunnels:ssh=ssh -p 20000"

but you must do this option every time you run the svn command. This might make sense for a build agent.


In case your ~/.subversion/config file does not have ssh tunnel defined, you can override ssh command on per-call basis using SVN_SSH environment variable

SVN_SSH='ssh -p 20000' svn co svn+ssh://server.com/home/svn/proj1 proj1 --username jm

For example

deo@fox:~$ SVN_SSH='ssh -v -p 20000' svn ls svn+ssh://svn/
OpenSSH_7.9p1 Debian-10, OpenSSL 1.1.1c  28 May 2019
debug1: Reading configuration data /etc/ssh/ssh_config

debug1: connect to address port 20000: Connection refused
ssh: connect to host svn port 20000: Connection refused
svn: E170013: Unable to connect to a repository at URL 'svn+ssh://svn'
svn: E210002: To better debug SSH connection problems, remove the -q option from 'ssh' in the [tunnels] section of your Subversion configuration file.
svn: E210002: Network connection closed unexpectedly

This won't work if your ~/.subversion/config file does define ssh tunnel, in that case config file takes precedence. (Which is rather unusual. Normally it's other way around, environment variables usually take precedence over config files)
