Check this out. I ran the ‘openssl speed’ benchmark in Ubunto Desktop 10.0.4 in Fusion 3.0.2 and again in 3.1. The difference is pretty impressive. Link Summaryhttp://dreness.com/bits/tech/openssl-speed-fusion-3.0.2.txthttp://dreness.com/bits/tech/openssl-speed-fusion-3.1.txt
It’s a beautiful Sunday morning, and as you wait for the coffee to start working, you figure it’s probably about time that you started on those benchmark results that have to be done by Monday. You’re sitting there thinking “MAN I wish I’d provisioned a larger boot volume for these Mac Minis, I keep filling [...]
I was recently discussing Mac OS X / Active Directory integration with a friend, and one of the things I mentioned was the local static / variable mappings feature of the Mac OS X LDAPv3 plugin. After some fairly extensive internet searching, it appears that the only reason I know about that feature is because [...]
Mac OS X makes extensive use of a variety of event notification mechanisms, as described here. One such mechanism is documented in the notify(3) man pages, and it is these types of libnotify notifications that are the focus of this post. Notifications can be posted and observed in a global namespace across all processes (with [...]
It’s “hack some shit up” Friday. Everybody ready? Have a Time Capsule or Mac OS X Server configured to provide network time machine backups? Of course you do! Let’s examine the client / server interaction. The Time Machine preference pane provides a list of available backup volumes. This list includes local volumes as well as [...]
The following is an IRC transcript taken from #afp548, irc.freenode.net. It chronicles the troubleshooting process of a fairly well-hidden edge case of Kerberos configuration in Mac OS X Server. pastebin.ca was used to relay larger hunks of textual information; I’ve made local copies of the results since the pastebin pages expire in 1 month. Pastebin [...]
motivation I finally found a reason to write some Python. Being something of a monitoring and data junkie, I’ve had a fair amount of experience with snmp, data mining scripts, etc. After writing this post to the server list, I figured I’d make some templates for snmp that published interesting pieces of data about the [...]
In wrote the following as part of my response to this. #!/usr/bin/perl -w use strict; # Place the first three octets here. my $AddressPrefix = “10.0.1″; # Define the range of numbers, inclusive. my $range = “2 .. 10″; # Your fqdn suffix here, e.g. “foo.com” or “k12.fl.us.gov” my $tld = “937″; # Need a [...]
/usr/bin/split and /bin/cat, that is. Why is this useful information? Let’s imagine a wonderful world in which your web host gives you oodles of bandwidth and disk quota, and then one day secretly enacts a policy that disallows access to files over a certain (largish) size. Say, something like: [Tue Jan 02 13:07:24 2007] [error] [...]
Dealing with CPAN has always felt a little weird. Today I found a nice shortcut for getting perl modules installed in a home directory, which is really useful for when you don’t have admin on the box, or if you simply prefer to keep your custom perl stuff all cinched up in a tidy homedir [...]
Mac OS X Server, as of Tiger, has a spiffy little UI in the Server Admin tool for creating SSL certificate requests, importing certs, or creating self-signed certs. It’s pretty easy to make it all work for http or LDAP using the GUI tools. There is also the command-line ‘serveradmin’ tool, which attempts to mirror [...]
{10} andre@werk [~] % mount | grep /Volumes/andre afp_006Af01nOUmc001Eic06SdO0-1.2c0000ae on /Volumes/andre (nodev, nosuid, mounted by andre) Huh? how helpful is that! How can I tell what server it came from? Yeah, I could netstat, but what if there’s a bunch of AFP sessions open? DisplayURL to the rescue! {12} andre@werk [~] % ~dre/bin/DisplayURL /Volumes/andre url: [...]

I was using Server Assistant to do a remote setup of Mac OS X Server, and for some reason Server Assistant hung. When I relaunched it, the target server would not allow me to start over or continue the remote setup, claiming that it was already being remotely configured (clearly it didn’t notice that Server [...]
