SSH autocompletion issue

[ibc]

OSX 10.9.1 and zsh 5.0.4 installed with brew. Also installed zsh-completions and, of course, oh-my-zsh which is properly working, except this issue:

I've previously wrote "ssh myhost.com" to connect to my server. Then, if later I write "ssh myhost.mydoma" and press TAB, I do NOT get autocompletion. Using Bash I get autocompletion.

Second issue. If I add a host entry in ".ssh/config":

Host home
    hostname    myhost.com
    port        222
    user        alice

and then I type (using zsh) "ssh myh" and press TAB I get something ugly and invalid:

ssh \[my.host\]:222

Again, it properly works if I switch to Bash.

Your first issue is just a missing feature, feel free to implement it yourself.

Your second issue is disturbing, but there is an easy workaround: just complete the alias of the host. Here it is home, so you can do:

ssh ho[TAB]

and it will complete to:

ssh home

So I found the bug causing your second issue and submitted a fix: #2489

Fell free to comment. Maybe the colon and port number should also be removed?

About your first issue: this behavior indicates that the host is not in your known_hosts files. Can you please check them when the issue occurs?

Sorry for the delay in the response.

About the first issue: I think you are right. If I can reproduce it again I will re-open it.

About the second issue: The pull request #2489 does fix the brackets problem, and indeed, it should remove the port number since it is wrong. BTW it would be great if it would add "-p PORT" (for ssh) and "-P PORT" (for scp) if port appears in the know_files entry :)

Thanks for the update.

Good to know the patch works. I will update it to also remove the port number, but I am afraid that adding the -p 1234 will not be easy.

[ibc]

Thanks a lot!
Don't worry for the "-p PORT" feature, it would be too much cool ;)

[ncanceill]

@ibc OK now #2489 properly trims the port number

For info, I tried to implement your feature: replacing : by -p. But it does not work because completion always escapes, so it yields ssh address\ -p\ port and the backslashes make ssh see that as the whole address.

In the end, as soon as you are going to connect multiple times to a specific host, I strongly recommend that you create an alias in your .ssh/config and complete for the alias instead of the address. When you use the alias, ssh reads your config, and there is no need to specify the port number or anything else.
If you just want to complete for a recent host without an alias, you will have to remember the port number yourself.

[ibc]

Yes, I already make extensive usage of .ssh/config :)

Let me close the issue as it is 100% fixed. Thanks a lot.
