Does your /etc/nsswitch.conf have a dns option in the hosts line ? ie. hosts: files dns I imagine it will do, but worth checking. 2. Is your firewall allowing dns traffic in from BT's name servers?? You could try rerunning the firewall script and it may create entries in line with your /etc/resolv.conf. Alternatively put them in by hand -A input -s 213.120.62.101 53 -d 0.0.0.0/0.0.0.0 -i ppp0 -p 17 -j ACCEPT -A input -s 213.120.62.100 53 -d 0.0.0.0/0.0.0.0 -i ppp0 -p 17 -j ACCEPT Hope this helps Tom Liste de diffusion modem ALCATEL SpeedTouch USB Pour se désinscrire : mailto:[EMAIL PROTECTED]?subject=unsubscribe

Remove/comment the "GATEWAY=192.168.0.1" line from /etc/sysconfig/network. DNS check /etc/resolv.conf. I don't think that pppd replaces it, it creates its own copy. You have several solutions possible. 1. symlink /etc/resolv.conf to /etc/ppp/resolv.conf (I think). 2. Hard code the dns servers into /etc/resolv.conf (I use 194.73.73.94 and 194.73.73.95 or 3. Set up a DNS server locally. (I do this and use the BT servers as forwarders to reduce the load on the root servers but means that I don't suffer from their unreliability) Also check if you installed a firewall. Maybe DNS traffic is firewalled. Does RH7.3 install iptables or ipchains. If ipchains then DNS is probably firewalled as UDP is hard/impossible to filter properly using a packet filter. > I'm running kernel 2.4.18-5smp, and the latest drivers downloaded from > your sourceforge site.

Try /etc/init.d/ipchains stop or /etc/init.d/iptables stop and see if that fixes things. (If it does then you need to sort out the firewall as the above disable it completely which you really don't want on adsl.) Finally, are you running apache or openssh. If so please upgrade them before you get hacked. AFAICT apache on linux and openssh on RH (default install) have, as yet no known way to exploit them but apache on *bsd was believed safe as well until a (brilliant but annoying) piece of work by gobbles. upgrades can be got from ftp://updates.redhat.com - or ftp:://ftp.mirror.ac.uk/sites/ftp.mirror.ac.uk which tends to be faster but 1/2 to 1 day behind updates.redhat.com. I think RH now has an automatic upgrader as well but I like to do these things manually so that I know what has changed.

[speedtouch] Re: Problems with speedtouch and redhat
Thanks Tom & Tim. My gateway was wrong. The firwall was blocking all dns traffic. Other nasty things where going on. With a lot of fiddling, I have it working now. I'm using iptables to masquerade traffic from eth0 out to the big wide world. Cool. Now to set up a DHCP server for all these windows boxes in the house. Outstanding issues (not showstoppers) 1) modem_run is still taking random amounts of time to run (sometimes 15 minutes) 2) the ppp scripts aren't automaticaly updating my gateway 3) how do I load up the adsl connectin on boot automaticaly? Thanks for all your help, Matthew Liste de diffusion modem ALCATEL SpeedTouch USB Pour se désinscrire : mailto:[EMAIL PROTECTED]?subject=unsubscribe

If you want it then mail me. I'll give it a go with the .o file as well. > 2) the ppp scripts aren't automaticaly updating my gateway Do you still get the 'cant override default route' message ? Remove the gateway line in your /etc/sysconfig/network-scripts/ifcfg-eth0, mine looks like this DEVICE=eth0 BOOTPROTO=static IPADDR=192.168.0.2 NETMASK=255.255.255.0 #GATEWAY=192.168.0.1 > 3) how do I load up the adsl connectin on boot automaticaly? Within the source directory there are 2 files in doc-linux [root@trevor doc-linux]# pwd /usr/local/src/speedtouch-1.1/doc-linux [root@trevor doc-linux]# ls -l speedtouch.* -rw-r--r--1 1000 1000 741 Jun 1 00:34 speedtouch.conf -rwxr-xr-x1 1000 1000 9129 Jun 1 00:34 speedtouch.sh copy the first one into /etc and make the appropriate modifications, copy the second into /etc/init.d and then # chkconfig --add speedtouch.sh You can then use this script to stop / start the connection.

I should realy set up DNS and DHCP services on my linux box.

Thanks Tom, I'll try this. I had downloaded the rpm release.

The .sys file initializes almost immediately. Perhaps there's a problem with run_modem and the .o file. So, for new users I recomend the .sys option. >>2) the ppp scripts aren't automaticaly updating my gateway > > > Do you still get the 'cant override default route' message ? OK - this works now. Thanks. >>3) how do I load up the adsl connectin on boot automaticaly? > > -rw-r--r--1 1000 1000 741 Jun 1 00:34 speedtouch.conf > -rwxr-xr-x1 1000 1000 9129 Jun 1 00:34 speedtouch.sh > # chkconfig --add speedtouch.sh Great. Once I had very carefuly filled out all the options in the config file, I got it to work. I am now dialed in on boot, and ppp-up.local symlinks the DNS info automatically. How cool is that! I've been playing with iptables, also got dhcpd and named to work (after a fassion), and all the PCs in the house seem to just work. Thanks to everyone who helped.
