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:~]$:ssh root@sum1 cat /root/id_rsa.pub root@lcent01.summitnjhome.com's password: ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEApnUSYyrM96qIBZKjwSNYycgeSv/FAKE-KEY-DATA--KEY-DATA-PWReyVuOn9Fb/uH/FAKE-KEY-DATA-+ttLzUELGrfn/n+FAKE-KEY-DATA-/FAKE-KEY-DATA-/FAKE-KEY-DATA-/FAKE-KEY-DATA-== bluethundr@lbsd8-2.summitnjhome.com [/code]
But I cannot cat / grep it in order to determine if this key is already in the authorized_hosts file of the remote host.
[code] [bluethundr@LBSD2:~]$:ssh root@sum1 grep `cat /root/id_rsa.pub` /root/.ssh/id_rsa.pub root@lcent01.summitnjhome.com'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@lbsd8-2.summitnjhome.com==: 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@lcent01.summitnjhome.com's password: id_rsa.pub 100% 417 0.4KB/s 00:00
KEY TRANSFERRED TO sum1 ./key-export.sh: /bin/grep: not found root@lcent01.summitnjhome.com'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@lcent01.summitnjhome.com's password: Last login: Fri Sep 24 07:34:02 2010 from 192.168.1.44 ######################################################### # SUMMITNJHOME.COM # # TITLE: LCENT01 BOX # # LOCATION: SUMMIT BASEMENT # # # #########################################################
[root@LCENT01:~]#which grep /bin/grep [root@LCENT01:~]#which cat /bin/cat [/code]
