Summary | 0000667: no stdout when ssh'ing and allocating a pty | ||||
Description | Using a 4.5.4 kernel-ml on CentOS 7, we've stumbled across a regression in which no stdout is returned when running an individual command via ssh *and* allocating a pseudo-terminal. Example: $ ssh -t user@centos-7.example.com "/bin/bash -c 'hostname -s'" Connection to centos-7.example.com closed. $ ssh -t user@centos-7.example.com "/bin/bash -c 'hostname -s; sleep 0.0000001'" centos-7 Connection to centos-7.example.com closed. $ ssh user@centos-7.example.com "/bin/bash -c 'hostname -s'" centos-7 NOTE: the first command did not return any output! | ||||
Additional Information | I've found at least one other community reported bug that encountered this as well, cf. https://github.com/ansible/ansible/issues/15549 | ||||

|
Is it certain that this is purely a kernel issue? Or can this be a combination of the kernel and the version of ssh used, as someone suggested in the ansible thread you quoted? |
|
I was able to bisect this by *only* changing the kernel and leaving everything else the same. |
|
Are you seeing this issue with the latest (4.7.0 at the moment) kernel-ml? |
|
I've retested on 4.7.2 and no longer see this issue. $ uname -r 4.7.2-1.el7.elrepo.x86_64 |
|
With that report, I am now closing this ticket as resolved. |
