RE: svn+ssh making too many requests

SSH connections require some expensive computation at startup, so the
maximum number of outstanding connections allowed is much lower than for
regular socket connections to prevent denial of service attacks by
connection flooding. This is governed by the MaxStartups value in the
/etc/ssh/sshd_config file. If no value is set explicitly, the default
is 10. You can experiment with setting this higher (we use it inhouse
for a parallel master-server cluster installer, so we set it to the # of
slaves in the cluster plus a little extra). If your server isn't
Internet facing, this might be an adequate workround for you if you
don't want to swap out TortoisePlink.

Hi, Ingmar,

> when using svn+ssh, TortoisePlink seems to open a new connection for
every atomic action. The remote sshd would lock me out due to excessive
conections. Is there any way to circumvent that?

Some SSH implementations support connection multiplexing:
http://en.wikipedia.org/wiki/Comparison_of_SSH_clients

Install one of those and reconfigure your TortoiseSVN to use that ssh
client instead of the default TortoisePlink (which is based on putty).

Best regards

Markus Schaber
