What do you think? I think that would be a good idea. The version string is unfortunately just "Twisted". That's actually OK for past versions since the bug goes back so far, but it would be a shame for future versions. I've filed https://twistedmatrix.com/trac/ticket/9424 with a patch to improve the version string. Assuming my patch is accepted, I think you could make "Twisted" be SSH_BUG_DEBUG and "Twisted_*" not. -- Colin Watson [cjwatson@xxxxxxxxxx] _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
