Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

On my home LinuxMint9 desktop, I use wvdial and us robotics modem usr5637 for dialup net connections. Itís always worked fine.
But for the past few days, Iíve been unable to connect. Iíve made no changes, have installed no new sw or upgrades, havenít changed wvdial.conf file.
Hereís what Iím getting in terminal window when I type wvdial: [note: this is not copy/pasted; it's transcribed, with my comments in brackets]
Carrier detected, waiting for prompt.
CVX Access Switch.
Access is restricted to authorized users only.
-Looks like a login prompt
-Looks like a password prompt.
-Valid commands are:
-Quit: hang up and disconnect
-Help List valid commands
Hmm..a prompt. Sending ďpppĒ
Ďpppí is not a valid command.
Valid commands are:
Quit: Hang up and disconnect
Help list valid commands
[this recurs 2 more times, then:]
Donít know3 what to do! Starting pppd and hoping for the best.
Starting pppd at Mon Apr 9 08:09:09 2012-04-09 Warning: Could not modify /etc/ppp/pap-secrets: Permission denied
PAP (Password Authentication Protocol) may be flaky.
Warning: Could not modify /etc/ppp/chap-secrets: Permission denied.
CHAP (Challenge Handshake) may be flaky.
Pid of pppd: 2228
Using interface ppp0
The PPP daemon has died: A modem hung up the phone (exit code=16)
[Then suggesting to check error codes, to check
/var/log/messages and man pages, which I canít interpret; then I get auto-reconnect with same stuff.
Using man pppd to check error code 16, itís
16: The link was terminated by the modem hanging up.]
Looking at /var/log/messages:
Ppp 2.4.5 started by jim_d, vid 1000
Using interface ppp0
LCP: timeout sending config-Requests
[then above is repeated]
Any idea what's going on? How should I troubleshoot? If the above info is not sufficient, please let me know what info you might need to help troubleshoot.
One thing, possibly related?--Starting about a week ago, when I log in, there's a delay in opening the programs I specified to open automatically on login--the screen stays blank for a few seconds, then the pgms open. Not a big deal, but I wonder if this is symptomatic of something, suggesting a larger problem than just dialup not working anymore.
