ssh_config format

[Francois LAURENT]

I all,

I try to configure ssh a.03.81.002 on 11.11 box, but i have a format problem in ssh_config file.

Keys are "user" and "user.pub" stored in /home/user/.ssh/ dir.

I want to use user dependent key name. So i tried to setup in ssh_config file in client's file :

IdentityFile $HOME/.ssh/$LOGNAME --> don't work
IdentityFile %h/.ssh/%u --> don't work

And then hard path for one test user :
IdentityFile /home/xxx/.ssh/xxx
with xxx a real user with keys --> IT'S WORKING !

Could you help me in telling me what is the format of "IdentityFile" for user dependent name ?

Thanks a lot for help

Regards.

Your syntax looks good, except for the env variables being used... don't use the varables. :)

It sounds to me that you're making the user changes to the system wide ssh_config /opt/ssh/etc/ssh_config rather than the user's ssh_config.

create $HOME/.ssh/ssh_config for that user. This file will only affect this user and not everyone on the box. Change the global ssh_config back to the default.

Also make sure that te user owns the $HOME/.ssh/ssh_config file and group/other aren't allowed write access.

Hope this helps,

Thanks Denver for your purpose,

the env variables aren't read (they're seted of course, it's ok in shell) but why ?

Putting ssh_config in user's home don't work too.

Thanks for any suggestions.

Regards.

last try :

ssh -i $HOME/.ssh/$LOGNAME server --> IS WORKING

with tusc -e trace :
grep -e HOME -e LOGNAME /tmp/tusc_ssh-i
env[5] @ 0x77ff043e: "LOGNAME=x051104"
env[13] @ 0x77ff04c8: "HOME=/home/system/x051104"
open("$HOME/.ssh/$LOGNAME", O_RDONLY|O_LARGEFILE, 0) ............... ERR#2 ENOENT
open("$HOME/.ssh/$LOGNAME", O_RDONLY|O_LARGEFILE, 0666) ............ ERR#2 ENOENT
open("$HOME/.ssh/$LOGNAME", O_RDONLY|O_LARGEFILE, 0666) ............ ERR#2 ENOENT
open("$HOME/.ssh/$LOGNAME.pub", O_RDONLY|O_LARGEFILE, 0666) ........ ERR#2 ENOENT




ssh server --> NOT working

with tusc -e trace :
grep -e HOME -e LOGNAME /tmp/tusc_ssh
env[5] @ 0x77ff0419: "LOGNAME=x051104"
env[13] @ 0x77ff04a3: "HOME=/home/system/x051104"
open("$HOME/.ssh/$LOGNAME", O_RDONLY|O_LARGEFILE, 0) ............... ERR#2 ENOENT
open("$HOME/.ssh/$LOGNAME", O_RDONLY|O_LARGEFILE, 0666) ............ ERR#2 ENOENT
open("$HOME/.ssh/$LOGNAME", O_RDONLY|O_LARGEFILE, 0666) ............ ERR#2 ENOENT
open("$HOME/.ssh/$LOGNAME.pub", O_RDONLY|O_LARGEFILE, 0666) ........ ERR#2 ENOENT
stat64("$HOME/.ssh/$LOGNAME", 0x77ff0d18) .......................... ERR#2 ENOENT




In the 2 case : $HOME and $LOGNAME look OK ...


thanks for help.

oops, sorry about the bad info before. rename $HOME/.ssh/ssh_config to $HOME/.ssh/config

Also use "ssh -vvv" for detailed output. If it's using the specified identity from your user's config, you'll see it.

also remember it won't work (or atleast it didn't work for me) if you put "IdentityFile=$HOME/.ssh/$LOGNAME" in the users $HOME/.ssh/config file. It has to be "IdentityFile=/home/user/.ssh/user". You'll see what I mean when you use the "-vvv" option with ssh for detailed info.

Hope this helps,

Hi Denver,

your turn around is ok, putting config file in home dir make my connection ok.
But i'm afraid the solution couldn't been applyed. i have script to create user on multiplaform and only on hpux i have this problem. So i don't want to make a particular case for hp boxes, to preserv equality between different OS.

Thanks a lot for your help
