Configuring Linux for Dialup Networking

• hnlinux201.tgz is version 2.01 of my SLIP setup. Right now it's horribly documented, but the install script takes care of most of what you need to worry about.
  Some relevant sendmail configuration is also included.

• You insist on using PPP instead of SLIP? I still recommend installing the above package for now (hnlinux 3.0 will include PPP support). But my current PPP configuration files and connect/disconnect scripts are in ppp-rmf.tgz. They should be installed in /etc/ppp/, and in addition to hnlinux.
  The SLIP stuff is much better at this point.
• I've recently installed Red Hat Linux 5.0, and decided to build my new PPP setup on top what it installs. (I use PPP when I'm not connecting to Homenet.)
  • I created /etc/ppp/ip-up.local to deal better with dynamic IP, among other reasons (it works well for static IP too). I use a dummy ethernet interface labelled eth. as the interface to the local host under the most recently acquired IP address (and its name, since I assign its name to this IP address).
  • To start and stop the connection, I use a simple script called net, which calls Redhat's ifup and ifdown to do the work. ifup and ifdown figure out whether the calling using is root or not, and use the usernetctl command if it's not root.

• I don't do ResNet, but I do know that you need to set up DHCP to make it work right.

Mail & News

• There's a sendmail.cf or two included with the SLIP package above.
• The ultimate POP (and IMAP) mail retriever for Unix (especially Linux) is Fetchmail. It is based on the ubiquitous popclient, but fetchmail is much better.

Why I do it the way I do

Notes from the past year or two....

• My convoluted SLIP script was first inspired by these posts that appeared in comp.os.linux.networking back in mid-1995. Since then I haven't been satisfied with anything less.

• (more to come....)

Software

• I maintain a software archive at wks.uts.ohio-state.edu:/pub/solaris2/src/. It is primarily oriented toward Solaris, but most if not all of it is useful under Linux too.
