Hey,
Quick question for those of you that have been on top of the bug tracker
lately.
Both of the below issues were on a user's cluster running OSCAR-4.0 on RH9.
I can't confirm that he didn't make manual changes to break the system but
I sort of doubt that was the case based on what I did to "fix" things.
[Slow SSH]
I've experience an issue with a user of PVM, that ultimately turned out
to be a default SSH configuration issue. (We ssh for PVM_RSH.) The
problem was that ssh was *very* slow b/c Xauth was failing. If you did
an 'ssh -x' to disable Xforwarding at the client level things were
faster.
To cut to the chase, I modified the user's /etc/ssh/ssh_config so that
the client on the headnode didn't try to setup X11Forwarding by default.
However, I'm not sure why this was happening or if this was particular to
this user...but it sure was a problem and if others are having it we need
to fix in in v4.1.
[MANPATH]
The MANPATH bug seems to still be around. This is the problem where
stock manual pages are not available b/c we define MANPATH but don't
leave the "::" (search the system areas too). The manual fix is easy,
export MANPATH=$MANPATH:
The correct fix (which I thought was in but maybe it is not) is to have
switcher/modules insert this "default" manpath search item at the end (or
beginning) after (before) all the OSCAR modules are loaded.
I think that at sometime in the future when we have sufficient
documentation on how to write an APItest (i'm working on getting this), we
should have new tests written for known bug fixes to make sure they don't
crop back up...or that they're genuinely fixed. They wouldn't have to run
via test_cluster or the GUI but could be run manually by a developer or for
diagnostics by a user.
oscar on!
