I signed up with rsync.net for an off-site filesystem. Opted for geo-redundant version (automated nightly replication to other site) located in Zurich, Switzerland. Very fast speed from Europe and Qatar, good speed with US hosts. Very easy to use from Mac OS X, FreeBSD, Linux and Windows (rsync, ftp, scp, sftp, ssh, WebDAV). Direct integration in Finder, just use “Connect to Server” and enter the hostname address with https. On Linux and FreeBSD 6.x sshfs works like a charm. Easy to install on FreeBSD using ports, just cd /usr/ports/sysutils/fusefs-sshfs and run make install clean.

Learned the hard way: NEVER COMPILE ip_conntrack into the Linux kernel… 🙂

The fourth opensource PDC (Primary Domain Controller) using samba, with a openldap backend for storing users, groups and computers. It can replace a Microsoft Windows Domain Controller.

Provides central authentication services, file and printer sharing for Windows and Unix clients. Local logon credentials are taken from LDAP, too.

Tested on fedora core 4 and slackware 10.2.

Just got two Asus WL-500g!

WRT54gG v5 does not work with custom firmares! 🙁

I think this is a bad move from Linksys/Cisco as most of the pieces sold were used with custom firware.
Need to use other wireless routers, such as Asus, Netgear.
