[ILUG] wierd ssh thing

[John P . Looney]

 And, a wierder ssh thing;


[netsaint at angel netsaint]$ ssh -l root evilxander df
[netsaint at angel netsaint]$ ssh -l root evilxander 'df'
[netsaint at angel netsaint]$ ssh -l root evilxander 'df 1>&1'
Filesystem           1k-blocks      Used Available Use% Mounted on

[netsaint at angel netsaint]$ ssh -l root evilxander bash
echo hello
hello
ls
Maildir
courier.tgz
database.tgz
postfix-20010204.tar.gz
snapshot-20010204

 So, why doesn't df print anything to stdout, by default ? Why does it
have to be forced ? I'm trying to work out why netsaint won't ssh to
machines to run monitoring commands, and instead gives crap errors like -

    You have no controlling tty. Cannot read passphrase. 

 - when it shouldn't need one (as shown above, it'll ssh in fine..)
