We use a special ssh proxy which forces me to connect to servers using this syntax:
Btw: this proxy is called PSMP and belongs to the CyberArk product suite, it is not a jump or bastion host, although is seems to be similar because I do not have direct access to the servers and only the proxy is reachable.
To shorten this I tried the following
Host server HostName firstname.lastname@example.org@crappysshproxy.sub.domain User myuser
Why I then do
ssh server I get
ssh: Could not resolve hostname email@example.com@crappysshproxy.sub.domain: Name or service not known.
I tried to add these ...
CheckHostIP no VerifyHostKeyDNS no
... to my ssh config and this ...
... to the global ssh config.
Can I keep ssh from doing a DNS lookup and make it just use
HostName for connections ?
I am not searching for a solution that makes me create shortcut bash scripts like
server.sh that does the concatenation for me and I do not want to alias / replace the ssh command.
