Hello,
I am attempting to grep the contents of a key file I have SCP'd to a
remote server. I am able to cat it:
[code]
[bluethundr@LBSD2:~]$:ssh root@sum1 cat /root/id_rsa.pub
root@xxxxxxxxxxxxxxxxxxxxxxxx's password:
ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEApnUSYyrM96qIBZKjwSNYycgeSv/FAKE-KEY-DATA--KEY-DATA-PWReyVuOn9Fb/uH/FAKE-KEY-DATA-+ttLzUELGrfn/n+FAKE-KEY-DATA-/FAKE-KEY-DATA-/FAKE-KEY-DATA-/FAKE-KEY-DATA-==
bluethundr@xxxxxxxxxxxxxxxxxxxxxxxx
[/code]
But I cannot cat / grep it in order to determine if this key is
already in the authorized_hosts file of the remote host.
[code]
[bluethundr@LBSD2:~]$:ssh root@sum1 grep `cat /root/id_rsa.pub`
/root/.ssh/id_rsa.pub
root@xxxxxxxxxxxxxxxxxxxxxxxx's password:
/root/.ssh/id_rsa.pub:ssh-rsa ssh-rsa
AAAAB3NzaC1yc2EAAAABIwAAAQEApnUSYyrM96qIBZKjwSNYycgeSv/FAKE-KEY-DATA--KEY-DATA-PWReyVuOn9Fb/uH/FAKE-KEY-DATA-+ttLzUELGrfn/n+FAKE-KEY-DATA-/FAKE-KEY-DATA-/FAKE-KEY-DATA-/FAKE-KEY-DATA-==
bluethundr@xxxxxxxxxxxxxxxxxxxxxxxx==: No such file or directory
grep: root@bt-laptop: No such file or directory
[/code]
Ultimately, what I would like to do is script this in order to
automate this process:
[code]
#!/bin/sh
HOSTS="sum1 sum2 virt1 virt2 virt3 virt4 virt5 virt6 virt7"
SSHDIR=~/.ssh
RSYNC=/usr/local/bin/rsync
KEYFILE=/home/bluethundr/.ssh/id_rsa.pub
CAT='/bin/cat'
GREP='/bin/grep'
for h in $HOSTS ; do
scp $KEYFILE root@$h:~/
if [ $? = 0 ]; then
echo ; echo ; echo
echo "KEY TRANSFERRED TO $h"
else
echo "KEY Transfer To $h has FAILED"
exit 1
fi
ssh root@$h $CAT /root/id_rsa.pub | $GREP -i /root/.ssh/authorized_keys
if [ $? = 1 ]; then
ssh root@$h $CAT /root/id_rsa.pub >> /root/.ssh/authorized_keys
if [ $? = 0 ]; then
echo ; echo ; echo
echo "KEY APPENDED TO $h Authorized Hosts"
else
echo "KEY APPEND FAILED"
fi
exit 1
fi
done
[/code]
This is what results from the above script:
[code]
[bluethundr@LBSD2:~/bin]$:./key-export.sh
root@xxxxxxxxxxxxxxxxxxxxxxxx's password:
id_rsa.pub
100% 417
0.4KB/s 00:00
KEY TRANSFERRED TO sum1
./key-export.sh: /bin/grep: not found
root@xxxxxxxxxxxxxxxxxxxxxxxx's password:
[/code]
And I'm pretty sure I have those variables set correctly in order to
execute those commands:
[code]
[bluethundr@LBSD2:~/bin]$:ssh root@sum1
root@xxxxxxxxxxxxxxxxxxxxxxxx's password:
