Hi List,
Happy New Years and I was hoping to get some help on an ssh issue
that I am having. For some reason I am unable to scp to hosts on this
network using RSA keys. Here is what I am doing/what is going on;
scp the public key to remote host
[amandabackup@VIRTCENT18 ~]$ scp ~/.ssh/id_rsa_amdump.pub amandabackup@lb1:~
amandabackup@lb1's password:
id_rsa_amdump.pub
100% 408 0.4KB/s 00:00
ssh (w/passwd) to remote host
[amandabackup@VIRTCENT18 ~]$ ssh lb1
amandabackup@lb1's password:
Last login: Fri Dec 31 10:57:05 2010 from 192.168.1.40

check to see if the key exists in authorized_keys
[amandabackup@VIRTCENT01 ~]$ grep -f id_rsa_amdump.pub ~/.ssh/authorized_keys
it didn't so cat it into authorized_keys
[amandabackup@VIRTCENT01 ~]$ cat id_rsa_amdump.pub >> ~/.ssh/authorized_keys
check again, just to make sure that it's there
[amandabackup@VIRTCENT01 ~]$ grep -f id_rsa_amdump.pub ~/.ssh/authorized_keys
ssh-rsa BlAB3Nza/FAKE-KEY-DATA--KEY-DATAKfMq4DDa0xaKb/FAKE-KEY-DATA--KEY-DATAsoqCu/boKNa/FAKE-KEY-DATA--KEY-DATAp1n9TcDtxm2XFHcOKUw2/14/bz1pWNDI/FAKE-KEY-DATA--KEY-DATAr9951JdK7Ny6lk/FAKE-KEY-DATA--KEY-DATA1/FAKE-KEY-DATA--KEY-DATAwh2dmgyxI9N69x3ypvWcGWShZw1BCJI06j5qIxvin99/FAKE-KEY-DATA--KEY-DATA
It is. so good so far. Check permissions on authorized_keys file
[amandabackup@VIRTCENT01 ~]$ ls -l ~/.ssh/authorized_keys
-rw------- 1 amandabackup disk 408 Dec 31 11:02
/var/lib/amanda/.ssh/authorized_keys
make sure we have the right home environment
HOME=/var/lib/amanda
Also good. Now, make sure ssh is looking at the right file
[root@VIRTCENT01 ~]# grep -i authorizedkeysfile /etc/ssh/sshd_config
AuthorizedKeysFile ~/.ssh/authorized_keys
It is. Now exit and try to ssh in
[amandabackup@VIRTCENT01 ~]$ exit
Connection to lb1 closed.
[amandabackup@VIRTCENT18 ~]$ ssh -vvv amandabackup@lb1
