| Post subject: | Howto ssh mythtv through sh script |
I am used to pass commands from my MBE to any SBE in my network via ssh. This is useful to gather information about the SBEs state before switch them off. I normally did this by an sh script and ssh configured to grant access without password. Since LinHES does not permit ssh being used without password I had to do it in a differente way. The solution is sshpass, a tiny program that permits to send the password to ssh even from sh scripts. Here is the procedure I used to add sshpass to my LinHES MBE and to grant SBE access. First it needs to assign a password to mythtv account in any SBE in the network (I have 2 SBEs) and a few configuration: sudo passwd mythtv <type the new password twice) sudo nano /etc/ssh/sshd_config and type # before DenyUsers mythtv #From MBE type: ssh mythtv@<IP of your SBE> (to do just once for each SBE) answer with yes whenever requested Then to compile sshpass from source in this way: sudo pacman -S make wget http://downloads.sourceforge.net/sshpas ... .04.tar.gz tar zxvf sshpass-1.04.tar.gz cd sshpass-1.04 ./configure make sudo make install To check if it works: /usr/local/bin/sshpass -p 'mythtvpassword' ssh mythtv@<IP of your SBE> Enjoy last edited In my scripts I've also used this way: sudo /usr/local/bin/sshpass -p '<passwd>' ssh -o StrictHostKeyChecking=no mythtv@<IP_ADDR> "sudo /home/mythtv/bin/ShutdownCheck" |
