invalid login from unknown user 'gps-arm64-debian' #502

Closed vstinner closed 1 month ago

vstinner commented 1 month ago

The "gps-arm64-debian" builder was removed by commit 7bc844ede3c962258ad68c886d6df1907035c51b. But it still tries to connect time to time:

There are 3 "unknown users":

$ grep 'invalid login from unknown user' master/twistd.log|sed 's!.*] !!g'|sort -u
invalid login from unknown user 'gps-arm64-debian'
invalid login from unknown user 'gps-clang-ubsan'
invalid login from unknown user 'gps-debian-profile-opt'

That means those virtual machines hosted by my former employer are still running.

I think Thomas Wouters (cc'd) has access to them via the "CPython Buildbots" project on his cloud.google.com console on his corp account and can shut them down and delete them.

Theoretically, I've fixed this by re-adding the workers and then doing a 'Force Shutdown' from https://buildbot.python.org/#/workers/106 (also 107 and 108), then removing them again. @Yhg1s may still want to actually shut them down, but they should stop trying to reconnect unless they get automatically restarted by some of their own configuration.

I think I finally managed to shut these down, so :fingers crossed: they should no longer be a problem.
