Issues with ssh to 2820 was created by jedi98
Since I upgraded most of my machines to the latest version of my linux distro I cannot ssh to either of my 2820 routers.
I can ssh to anything else.
I can telnet to the 2820s
I can ssh from an older system.
The crucial point is the version of ssh: -
Older system which works: OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007
Newer system which fails: OpenSSH_5.8p1, OpenSSL 1.0.0c 2 Dec 2010
Anyone have thoughts, ideas, workarounds, similar experience?

Ah ha!! Found the workaround, prevent ssh trying to allocate a pty.:
Still questions remain, why has it changed, is it ssh's fault or the 2820 ssh implementation?
Also what does not allocating a pty really mean in this context of a router command line?
Code:
ssh -T
