Conflicting message in host terminal #2503

Open abuehrle opened 7 years ago

abuehrle commented 7 years ago

This is a benign message but why does it appear? Using the Host terminal (on Master), I get:

mesg: ttyname failed: Success

It sorts itself out, but just thought I'd file this as an fyi.

@abuehrle what Linux distribution was the host running?

abuehrle commented 7 years ago

uname -r says:

4.4.0-75-generic

Linux Master-01 4.4.0-75-generic #96-Ubuntu SMP Thu Apr 20 09:56:33 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

2opremio commented 7 years ago

That's the kernel version. What distribution was it? Is it a cloud instance? uname -a may help

abuehrle commented 7 years ago

Yes it's the same instance where the terminal is failing. You have an invite to that one: https://cloud.weave.works/app/cold-hill-34

I am seeing this in Weave Cloud dev and prod. The error also appears when executing /bin/bash -l inside a host terminal there.

This seems be a known problem with glibc. Perhaps we can work around it somehow.
