FreeBSD NIS server + Linux NIS client

Today I installed Fedora on my Desktop machine and tried to get it to talk to my NIS/NFS Server. I’ve run a NIS/NFS for a long while. It saves me my hair. But it’s always been FreeBSD on both sides. That’s easy to do. The FreeBSD handbook explains it quite well. I’ve been dipping my toe into the Linux waters alot lately and I figured that the next thing to put together was a Linux Client for my NIS/NFS server. The NFS part is easy. I used the automounter (amd) and the configuration is the same for both Linux and FreeBSD but NIS is another story. For my setup FreeBSS NIS server, Linux NIS client you need this patch to thefile: /var/yp/Makefile.dist on your server. Rebuild the maps and make sure that you have the automounter working and you should be good to go.

Greylisting via Spamd


After far too long I’ve finally setup spamd to greylist inbound mail into This is something that I should have done a while ago. Before spamd I used a simple filtering setup for email based on Spam Assassin and using SA’s Bayes filter. It works okay but I was never happy with the performance that it needed from my box. When I first started this I was able to handle all the mail for on a SparcStation 20 running OpenBSD. That’s not really special since I typically have less than 5 users. Disk space concerns forced me to upgrade to a VA Linux 2200, still running OpenBSD. That’s been very good but I’m now running into the same problems that I’ve had before. If there is any holdup in the mail system then the mail server gets hammered while the MX boxes on the internet offload mail. It’s easy to figure out why this is. I just look at the count of messages in my spam and junkmail folders. Lets see 376 messages in spam and another 246 in junkmail. That’s about 3 days worth of mail. That’s right. Despite Javascript veiling and everything else I do I get over 150 spams per day. Or at least I did until I started running spamd!
