SSH between 2 routers - trouble setting up keys

[mcouture]

I am having trouble with being able to have SSH between 2 routers using keys.


I can get it so my workstation can Putty into the routers with keys, but I cannot get dropbear to work between both routers.

Latest try:

- dropbearkey -t rsa -f id_rsa
- create the id_rsa.pub from the output above (just the public section)
- copy id_rsa.pub to remote router (into GUI)
- on local router, ssh -i id_rsa userid@far-router-address

What am I missing?

copy id_rsa.pub to remote router (into GUI)

What error are you getting?

Couple of things to check:

• I'm assuming you are allowing ssh connections from outside, in your remote router (just mentioning this in case you overlooked)
• See if your remote router's port 22 is visible from your local router (if you have entware, install nmap and try nmap -p T:22 <remote_router>)
• If you are able to, also make sure the ~/.ssh/authorized_keys on the remote router has 600 or 700 for octal permissions (if you are doing it in the UI, this should be automatically done)

Ah shucks....

It looks like I copied the public key with the "fingerprint" line....so once I got that out of there, I am able to ssh without passwords!

Thanks for helping redhat27!
