ssh config

[Mike Ayers]

I'm trying to set up shortcuts in ~/.ssh/config, but it doesn't seem to 
work.  I add:

Host slate
Hostname quarry.slate-gravel.com
User fred

...but when I try to use it:

[SNIP]
host ssh slate
ssh: Could not resolve hostname slate: no address associated with name
host
[/SNIP]

What am I missing here?


Thanks,

Mike

Check your /etc/passwd file
It's possible that ~ isn't really your home directory

Well that was it, thanks, but why is ssh looking there?  I thought it 
(and all other apps) used HOME on cygwin?


Thanks,

Mike

Nope.  But if you think about it, if $HOME doesn't equal ~ for Cygwin,
something has gone awry.  Given that as context, it really wouldn't matter
whether '/etc/passwd' or $HOME was the source.

So it gets ~ from /etc/passwd?  Ah - didn't know that.  I'll check it 
in the future.  I do think of cygwin as a Windows environment more than Unix, 
so some of these things get by me.  In years past, I would just set HOME and 
all was well.


Thanks,

Mike

Let's clarify something here.

~ is always the same as $HOME.  If you change $HOME - within bash -
then ~ changes too:

$ HOME=/bogus/directory
$ echo ~
/bogus/directory

HOME starts out set to whatever's in /etc/passwd, but you can change
it.  For that reason, security-conscious programs like ssh ignore
$HOME and go by what's in /etc/passwd (which, on a real Unix system,
an unprivileged user can't change).

So changing $HOME is asking for trouble, basically.
