I've scanned the log files and didn't see any unusual error messages. But that could be because I don't know what to look for. I've run FreeBSD for just about one year and had no Unix experience prior to that at all. I jumped from Windows, where somebody did everything for me to, FreeBSD where I have to figure things out on my own with only hints and suggestions. (Honestly, I find it funner this way!) I'll check to logs next time it goes down. I copied the results from ifconfig when everything is working to a file. As soon as I lose the connection I'll run ifconfig again. To get more defined regarding the loss of connection, it's almost as if I typed ipfw flush as root and cut myself down to the default deny everything rule. Sent emails will set unprocessed in the queue, when attempting to download e-mail, K-mail will return an unknown host error message, web browsers will either open to a blank white page or give me an invalid ULR error message. It even went down while viewing a video on Xine. The video just stopped, then I got an invalid host error message. As soon as I type /etc/netstart. Boom! everythings up an running as if nothing was ever wrong. I saw your other email as well, which shows that ifconfig during up/down is the same. That means that you're not losing your IP address, and the fact that /etc/netstart fixes the problem probably means it's not hardware related. So the next steps are to tear apart the networking system and figure out exactly which part of it is shutting off. First, do these: 1) Copy /etc/resolv.conf to your home dir: this contains your DNS server information. 2) Save the output of `netstat -rn` (use something like `netstat -rn /home/username/netstat.txt` This is your routing table. Now ... the next time it goes down, check: 1) Did /etc/resolv.conf change? 2) Did the output of `netstat -rn` change? 3) In the netstat output will be a line that starts with default, see if you can ping that IP address - if not, then the problem is probably with your switch/hub or other local network. 4) Try pinging 206.190.36.122 (that's the ip for story.news.yahoo.com), if it works, then the problem is likely with DNS. 5) if #4 works, try pinging story.news.yahoo.com ... if that fails, then DNS is almost certainly the problem, if that works, then the problem is somewhere in the network config, or application config. -- Bill Moran Potential Technologies http://www.potentialtech.com --- Thanks for the help. I believe you are correct in that it's probably not a hardware issue. I dual boot with Linux and I am having no problems connecting to the internet on that side. System didn't go down Wednesday, but it went down today. The output of netstat -rn didn't change. I tried to ping the IP address after the word default in line 3. Here is the output: nedsbsd# ping -a -c 3 -o 68.13.118.1 PING 68.13.118.1 (68.13.118.1): 56 data bytes ping: sendto: Permission denied ping: sendto: Permission
