Ports open? I don't think so. I run an Iridium/IPchains firewall, and yes that workstation provides Squid, Apache, NFS, FTP and sendmail server functions, not to mention caching name server. I also have a number of "permanent" SSH connections open to other systems. It's my main dual-head workstation and development machine, if your couldnt already tell.
No I have not changed the keyboard type yet, I'm not sure what to put into XF86Config-4 for that keyboard (and I NEVER run xconfigurator etc).
