Dear all, I have an Ubuntu 22.04 with Squid package, and I've
configured it in order to let pass ssh protocol to Internet.
From the own proxy, if I execute:
$ sftp -v -oConnectTimeout=20 -oPoxyCommand='nc -X connect -x
10.12.1.1:8080 %h %p' -oPort 60000 user@x.x.x.x
I can login successfully.
But if I try to connect with sftp from a host behind the proxy 10.12.1.1:8080:
$ sftp -v -oHostKeyAlgorithms=+ssh-dss -oConnectTimeout=20
-oPoxyCommand='nc -X connect -x 10.12.1.1:8080 %h %p' -oPort 60000
user@x.x.x.x
I get this error:
command-line line 0: Bad protocol 2 host key algorithms '+ssh-dss'.
Couldn't read packet: connection reset by peer.
you use option "HostKeyAlgorithms=+ssh-dss" and sftp does not like it.
What can be the cause of this error, trying to use sftp from a host
behind my Squid proxy?
This is not a squid issue, if it only happens with sftp.
it looks like your sftp client complaining, even without using proxy.
btw I use "connect-proxy" command instead of "nc"
