Pursuing your suggestion when I executed "ssh -l root -T remote /bin/true" I was greeted with "stdin: is not a tty".
My googling resulted in http://platonic.techfiz.info/2008/10/13/stdin-is-not-a-tty/ which indicates that the culprit is apparently "mesg y" in /etc/bashrc. After commenting out "mesg y" in my /etc/bashrc, "ssh -l root -T remote /bin/true" receives no output as you indicate is correct. I have kicked off a full backup and I'll see how it goes, but I'm sure that it will work properly now that the "stdin: is not a tty" is gone. For reference anyone hitting this on a search "mesg y" allows the 'wall' and 'talk' or other such commands to write to your TTY for intra-system chat on TTY's. Thank you everybody for your help in clearing this problem up! - Nick Bright Adam Goryachev wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Holger Parplies wrote: >> Nick Bright wrote on 2009-11-09 17:57:11 -0600 [Re: [BackupPC-users] Backup >> fails after running 8-10 hours]: >>> Les Mikesell wrote: >>>> Nick Bright wrote: >>>>> Got remote protocol 1768191091 >>>>> Fatal error (bad version): stdin: is not a tty >> note the error message here.
