Hi Perl Monks, I have a setup where through my Windows PC(cygwin) I am communicating to the linux system over ssh using Net::Expect::SSH The communication has work really good where i ran 100s of tests. In my tests, after every test failure I reboot the linux system. Intermittently, after reboot, when i try to communicate to the linux system over SSH, I see the below error of "No Pty allocated". I have no clue whats going on ?

. I realized that there are lot of orphaned SSH connections that i need to kill. Even after doing that, i still am seeing this issue

Could someone please advice ? Thanks.
