We have a performance problem in with active directory 2003: reverse lookup of object sids, particularly in ACLs and quotas, is very slow. Looking up user names in a long quota list may well take several hours; lookup of all users in an ACL can take 20s.
By contrast, performing a programmatic lookup (performing an LDAP search of objectSid) completes very fast.
What could be the source of this problem?
I'm trying to set up per-user trac instances, using fcgid. The problem is that trac requires rw access to the trac instance, so I need the fcgi process to run under the respective user.
I have the suexec, fcgid, and userdir Apache modules installed (on Debian). I put up vhost directive
ScriptAliasMatch /~(.*)/trac /home/$1/public_html/trac.fcgi
This works insofar as trac.fcgi is run, but unfortunately, under the www-data user. How can I make fcgid launch it under the $1 user?
I have created a number of dump files using Linux dump(8), using the -A option to get a table of contents on disk (the backups are on tape). Now I'm trying to look into these archive files, using
restore -i -A <archive>`
However, this insists on asking what tape to use, and complains if I say none. What am I doing incorrectly? I was hoping that I can use these archive index files without having to insert the tape to use.
I'd like to set up a git server over ssh, with a single SSH account for the project. All project members should have their ssh keys listed in authorized_keys. Lockdown should restrict access to only doing git stuff, and only inside a dedicated directory.
What is the best way to create such a setup? There is git-shell, which apparently can do the lock-down to only doing git commands, but I can't find out how to restrict access to a single directory. There are also various Python and Ruby wrappers - which of these should I trust?
Our RAID controller failed; it doesn't show up with a boot menu anymore, and the BIOS finds no disks. When we get a new controller, can we recreate the RAID set without losing data? IIUC, the controller has the configuration in RAM, not on disk (and yes, we have the extra batteries for the RAID controller installed - but that may not help as the controller is unresponsive).
