The SSH console is timing out and I'm not able to execute any commands.
I've noticed that I can execute commands remotely but when I try to allocate TTY it hangs:
$ ssh email@example.com "uname -a" Linux example.com 2.6.32-504.el6.x86_64 #1 SMP Tue Sep 16 01:56:35 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux
$ ssh -t firstname.lastname@example.org "uname -a" $ ssh email@example.com "dmesg" tty_ldisc_hangup: waiting (sshd) for pts1 took too long, but we keep waiting...
