The C language (which is what we discuss here in comp.lang.c) doesn't
have direct support for MD5; you'll have to find the algorithm for it
(if a web search doesn't turn anything up, you could try asking about
it in sci.crypt, but make sure you read their FAQ first to see if it
answers your question) and then implement that algorithm yourself.
(If your system uses MD5 passwords, and you have access to the source
code for its library, you might be able to cheat by looking at the source
for the crypt() function that most unices and clones thereof have.)
If, once you've found the algorithm, you run into problems with
implementing it in C, show us your code and tell us what the problem is,
and we'll try to help you fix it - answering questions about C is one
of the things we _do_ do here.

Hello,
you could use something like this:
if ! grep "/your_mountpoint" /etc/mtab > /dev/null;then echo "is not
mounted";else echo "is mounted";fi
Good luck

I remember there being a program call jslaunch, which stands
for JoystickLaunch. It uses the joystick port as trigger for
shutdowns etc. I guess faking a joystick button should not
be too complicated :-)

the return value from mount will tell you. So will the text output from
mount (but reading /proc/mounts directly will be preferable).

Don't be too sure of that. Whenever posters start asking about
/etc/shadow passwords -- and this is hardly the first time -- flags
should go up about malicious users or crackers. Those of us who have
been around awhile are very wary about helping people do malicious
or illegal things.

No doubt it is affected by this, as this determines the order in which
the drives are detected.

I remap only in lilo, I never touch the detection chain in the BIOS.
It would only confuse things.

Yep, tends to be a problem in mixed IDE/SCSI systems

Indeed,
I suppose the orders are: check IDE0(master/slave)->IDE1(master/slave)
and number in order of appearance.(BIOS changes will affect this)

Eventhough you're new to Linux, you can't be new to computers. What is
your question, exactly? How do you normally connect to internet, on your
Windows computer? Same way will apply to Linux. Whether you choose DSL or
56k modem will depend on other issues, not whether you use Linux or Windows.
RedHat is easy for a beginner, so that may be a good start.

Helps if you provide what distro and release level you are using
when you post questions to the news groups. Different distros
have different commands, files, and links to files. Even happens
between release levels of the same distribution.
To make sure you do not have a security problem:
Create a user account on Client.
Log in as the user and
telnet -l user Client
to verify telnet is working.
If still afu, check that you have enabled telnet in /etc/inetd.conf

I guess the floppy is physically damaged. Try re-create

(if your computer supports this). Try this first.

if [ $? -eq 0 ]; then

Try to mount the drive & pipe mount's messages to /dev/null.
Then, test the result by looking in $? 0 = good.

Rick,
It will be easier to help you if we know :
1. can you ping one box from the other ?
2. when you try to telnet, what error message (if any ) do you get?
3. what does the syslog on the machine you're connecting to say?

All discussions on Usenet will, no matter the original
topic, devolve into an argument about one or more of a couple dozen
recurring themes. These themes have been floating around the net for
years and show no signs of dying.
All discussions will become cross-posted to more and more irrelevant
newsgroups. If left unchecked, they would be cross-posted to every
single newsgroup eventually.
