Public Key/Private Key RSA SSH Authentication, incompatible versions?

[zackboll]

Ok, will I have set up RSA ssh authentication before with little trouble before on debian and ubuntu distributions.

ssh-keygen -t rsa
then copy the "id_rsa.pub" into the "authorized_keys" file of the machine you want to connect. The id_rsa.pub looks something like this

ssh-rsa AAAA......ADADJA== root@blimpserver

I am doing an embedded linux project for class, running kernel 2.4.19 on a Stargate PlatformX development board. There doesnt seem to be the same options for ssh-keygen on the development board, like no -t option, but it does an rsa key by default.

Usage: ssh-keygen [-lpqxXydc] [-b bits] [-f file] [-C comment] [-N new-pass] [-P pass]

The identity.pub file also looks to be in a different format than the one my ubuntu server generates.

1024 35 14086313064907804810825517866521754118140837784925939335542483411268937340836832370814748189386402763341891581043404901505678017426480983873972803085003900580822978532819897813923466834625755697493269579774465868721063813867611736786497600964906470036339471711155154505697952148024216972525547845887976856509 root@stargate

Its all numbers there is a 1024 and 35 in front. I am assumming the ubuntu ssh-keygen using base 64 to display number while the stargate is in decimal. Will anyway, I cannot not get passwordless ssh to work, I have mangled the /etc/ssh/ssh_config and sshd_config options endlessly and I am still unable to get it to work. I have tried adding the stargate's "identity.pub" to a "authorized_keys2" file on the ubuntu server but that still doesnt work. Posted below are the config files that I have edited in trying to get this to work.

"ssh_config"

# This is ssh client systemwide configuration file.  This file provides
# defaults for users, and the values can be changed in per-user configuration
# files or on the command line.

# Configuration data is parsed as follows:
#  1. command line options
#  2. user-specific file
#  3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.

Does anybody have an idea how I can get this working. I do have ssh-agent installed so I could use that, if it is not possible to get rsa pub/priv working. Any help would be greatly appreciated.

thanks,
Zack

Bump anyone? Would this post be better suited in a different section on these forums?

IMO, you posted this appropriately.

"kernel 2.4.19 on a Stargate PlatformX" ??

Your problem is totally obscure, which likely explains the lack of responses. What distro is it running? Is this something you built/compiled yourself?

I am currently running the images built by Crossbow
PlatformX with Stargate
They call it release 7.3

I may have to rebuild source with arm-gcc to get ppp functionality, I am still looking into that. On a side note, I got DSA authentication working but it is still a no go for RSA.
