I've been trying a method to use CVS with SSH using a middle machine as
a stepping stone to cvs.eu.openbsd.org.
4.6 ----- current ----- cvs.eu.openbsd.org
For regular ssh this works ok to other machines. CVS doesn't seem to
like it. The symptom is the message:
can't create temporary directory /tmp/cvs-serv29515
No space left on device
CVSROOT is 'anon...@anoncvs.eu.openbsd.org:/cvs'
CVS_RSH is 'ssh'
The connection to the middle machine succeeds:
debug1: Authentication succeeded (publickey).
but it appears that ssh_config on the client (4.6) is somehow wrong for
the connection onward to the cvs server.
Host anoncvs.eu.openbsd.org
Port 22
User anoncvs
Compression no
HostKeyAlias anoncvs.eu.openbsd.org
ProxyCommand ssh -vv 10.10.10.1 nc %h %p
Host net5501
Hostname 10.10.10.1
IdentityFile /home/foo/tunnel-rsa
User foo
Can/should that be done using netcat? The FAQ covers direct
connections, and mentions pservers for firewalls, but then also mentions
that pservers are mostly phased out.
http://www.openbsd.org/anoncvs.html#WHICH
Should a SOCKS5 proxy be used instead?
What is the correct way to get a connection all the way through?
