Note that there are also far better ways to track IP than by cronjob, and more efficient to boot. See the bottom of the message for details because I don't think it's part of your main problem. > After trying to tweek dhcp and the pppoe configurations on my SuSE 9.0 > machine Wait a sec. Which one are you using, DHCP or PPPoE? What provider are you using? I don't know of any that use both simultaneously. If you're using them both, they could very well be conflicting. I'd be surprised if you got a DHCP lease at all. Bear in mind that even getting a DHCP lease may not mean you're connected to anything. If I unplug my cable modem from the wall, it starts handing out leases in the private IP range (192.168.*). This allows me to access the modem's internal webserver to check its status. > This fits in with the earlier observation of being able to ping a > site but not load the page. Perhaps, although this is most commonly a too-high-MTU symptom. Note that setting the MTU isn't enough. You should set the TCP MSS as well. See a previous message I wrote this week on that subject. > The online DSL speed tests say things are OK, but after hitting the back > button it reports I have a T3. Sounds like something got cached. Anyway, tracking your IP without cron: For PPPoE, since you're using the PPP daemon, you'll probably find some directories in /etc/ppp that can contain scripts to run when PPP comes up or when it goes down. Mine's located at /etc/ppp/ip-up.d. In this directory, if I put an executable script there, it'll be run every time the PPP link comes up. If your distro doesn't have that, you can put your commands in /etc/ppp/ip-up, which (at least in my distro) is called when PPP comes up. Check the manpage for pppd. Note that the better DHCP clients have a similar system for when they acquire leases.
