I have a key that I converted and works fine with Putty.

I have tried these formats:

ssh -p 1111 -i id_rsa chip@

ssh -i id_rsa -p 1111 chip@

The key is in the same folder as the MobaXTerm executable.



[chip.client] $ ssh -p 1111 -i id_rsa chip@ -v

Can you run it with a "-v" option to show some debug output? – cjc Sep 1 '11 at 2:08
And what output you get? Did you take a look at ssh server logs? – quanta Sep 1 '11 at 2:36
Looks like I just don't know where to put the key. Added -v output to origional question. – Chip Sprague Sep 1 '11 at 14:25

MobaXterm by default uses the home directory location as windows Temp directory. So the keys you create will not be available as soon as you close MobaXterm.

Once the key is generated, keep that in a different folder in your windows drives and refer it by complete path in the "-i" option. The windows drives are referred as '/drives/c/', 'drives/d/' etc in MobaXterm. If the private key is kept at E:\keys\id_rsa then the command will look like,

ssh -p 1111 -i /drives/e/keys/id_rsa chip@

If you're using MobaXterm regularly, the best way to deal with this is to use a permanent location for the home directory rather than the default Temp directory. You can do this by going to Settings->Configuration->Miscellaneous Options -> Use the following persisten HOME directory. In this case the keys can stay in the home directory and you need not supply an "i" option

I'm not sure how MobaXTerm works, in terms of its login environment. Obviously from your output, ssh is looking for the key with the name /home/chip.ssh/id_rsa.

So, when you start up MobaXTerm, can you try some stuff, like running "pwd" and seeing what directory it thinks it's in and work on putting the key into there? In your ssh command, you should be able to specify the full path to the key with something like "ssh -i /path/to/ssh/key/id_rsa" plus the other ssh options you're using.

Alternatively, you may be able to specify some alternative path. If MobaXTerm is Cygwin based, you may be able to say something like "/cygdrive/c/Documents/ssh/id_rsa", which should correspond to "C:\Documents\ssh\id_rsa" on your filesystem.

pwd showed me it thinks it is in /home/X where X is the directory the .exe is in – Chip Sprague Sep 2 '11 at 1:32
When I try to use /home/X/id_rsa it tells me there is no such file or directory even though I do see it there :/ – Chip Sprague Sep 2 '11 at 1:35
OK, I just downloaded MobaXterm and gave it a try. I created a new key with "ssh-keygen". I'm not sure where /home/MobaXTerm actually is; it's some sort of virtual home someplace, it looks like. In any case, I was able to connect to my server by specifying: "ssh -i ./id_rsa -l username server" where id_rsa is my current directory. – cjc Sep 2 '11 at 2:59
Okay, your key file is "id_rsa" and it is in the same directory as MobaXTerm.exe? – Chip Sprague Sep 5 '11 at 13:28
The key was in /home/MobaXTerm. I don't know where that actually lives on the Windows filesystem. I didn't use an existing key; I created a new one in /home/MobaXTerm using "ssh-keygen". – cjc Sep 5 '11 at 13:40

If you already have keys setup via Putty or something else the easiest thing to do is to just copy paste them into the MobaXterm home directory.

Putty's default location is usually C:\users\.ssh

Copy and paste the keys into:C:\Users\*your computer name*\Documents\MobaXterm\home
