TIA Its a routing issue so make sure you enable IP forwarding and check if other systems see the MAC address associated with the IP address of the modem. Make sure that the IP of the modem is valid on the ethernet.
[SOLVED] Incoming PPP, slink
Bingo! Thanks. And do I love Debian, or what? Dial up the server with minicom, "make menuconfig" (not rendered as well as I'd like but I only had one option to change), "nohup make-kpkg " and log off. Check back after the compile has had time to complete, "dpkg -i kernel-image..." followed by "shutdown -r now". Wait for the disconnect. Pour a cup of coffee, call back in 5 minutes and (no surprise!) the server answers. All looks well, so boot into Windows (ugh!, but I gotta test this thing), use Dial Up Networking to contact the server, and all the TCP/IP stuff is fine. Still some problems related to the smb network, but I'll chase that at work on Monday where my samba books reside.

TIA > It may be that your server is not configured to perform IP forwarding. This is a kernel compile option. If you're running kernel v2.2, you must also enable forwarding at run-time; Try # cat /proc/sys/net/ipv4/ip_forward If the answer is "0" then forwarding is disabled; you can turn it on with # echo 1 > /proc/sys/net/ipv4/ip_forward It's also possible that you have IP firewall rules getting in the way. To check your routing rules, dialin from Win95 and then try # traceroute from a different box on the main LAN, and confirm that it gets at least as far as the server you've dialled in to.

Incoming PPP, slink
At work I administer an ethernet network of several dozen Win95 desktops and a couple of Linux boxen running samba. I'm trying to set up incoming PPP on an up-to-date Debian slink box. The goal is for an employee to be able to dialup this box from her Win95 machine at home and be a "full citizen" of the network. mgetty is installed, and I've followed the instructions for setting up incoming PPP for Win95 machines that exist in both the /usr/doc/ppp/ and /usr/doc/mgetty-doc/ directories. I can dialup and connect fine. The problem is this: The Win95 box sees only itself and the server---it can't reach any other boxes on the ethernet network. The reverse is also true---the server can ping the Win95 box when it's connected but none of the other boxes on the network (either Win95 or Linux) can ping the dialup box. First thought is a routing problem. Perusing the docs suggests that the server, through the PPP 'proxyarp' option, will "pretend" to the other machines on the network to be the dialup box. /var/log/ppp.log shows the proxyarp option "took," but nonetheless, there is no communication between the ppp0 and eth0 interfaces. Suggestions? TIA Cheers, Pann -- geek by nature, Linux by choice L I N U X .~. The Choice /V\ http://www.ourmanpann.com/linux/ of a GNU /( )\ Generation ^^-^^
