The only way I can think of that a process can fail to free all its memory
on exit is if it allocates shared memory and never destroys it. Try
running "ipcs" (as root) before and after running the program and see if
there is any shared memory left in use.
On the other hand, maybe you are miss-interpreting "free" output, which
often shows a lower "free memory" value than people expect. That's just the
way Linux works. If, for example, your program did a lot of disk I/O and
Linux grabbed a lot of memory for buffers, Linux won't necessarily free up
that memory until it has something better to do with it.

I didn't realise this wasn't fairly stable code, was running the 0.4b15-1
version which came with RH6.2. I've upgraded to b19 and it now works!!
thank you, I should always think of looking for upgrades before asking.

It's not odd at all. Probably it's just because the current
directory is not in your PATH, though there are a few other
possibilities: http://pcunix.com/newtounix.html#path covers
them..

Its called Opera. www.opera.com Its currently in Alpha stages for

seems faster than IE and is MUCH slimmer.
It is supposed to conform to all the HTML, XML, CSS, JavaScript,
ECMAScript standards. I have not tested it fully. But I do like the
speediness of the eval version for Windows.
It may not be the ideal choice since its not free...but it is...or
will be an option. I can only hope that its faster under Linux and
Free.

Are you doing a ./commandname or just commandname? Or
/directory/path/from/the/root/down/to/the/commandname?
When you do a ls -l on the command, are the executable bits turned on in the
permissions? Are these shell scripts, or binaries? If they are binaries,
try doing a sh -x commandname and seeing if it is some command in the script
that is not found, as opposed to the script name itself.

Subject: inittab messed up..
Date: Thu, 5 Oct 2000 19:39:12 -0700
I have started using linux recently, I have messed up /etc/inittab . Now
Linux doesn't start. It is Redhat Linux 6.2. I have changed the line
#Run gettys in standard run levels
1:2345:respawn:/sbin/mingetty tty1
to
1:2345:respawn:/sbin/vgetty modem
I was trying to run initialize vgetty.
Now linux box does not start at all and it is giving error at some point
while starting sshd2 and saying that "probably port 22 is already in use" .
It was working absolutely fine before. I have boot disk for that, if it
could be used. I think this is the problem, how can i change that file, for
this I have to get into the system which I can't .
I will appreciate if someone will reply soon.

I'd like to back up my hard drive onto CDR's. The problem is that I've
got about 3 gigabytes of data on my hard drive but I don't want to store
the files as tar or gzip files on the CDR's. Is there any way of making

Freeze right there. If you use malloc to create two pointers, they
will not have ANY bytes in common. You get a totally new, free, clear
and in all other way fresh chunk of memory with *no overlap* to any
other alloc'd memory.

Xconfigurator didn't ever get it, so I went with the old xf86config. And
here's the result. My card (set to run as an S3Virge), is actually an S3
86C325, which is unsupported.
And I have done some reading on the XFree86 version 4. And I know that
there is a new module loader, and I know that many drivers are being
rewritten to take advantage of these new features.
I also know that now I'm bitching about X in a RedHat discussion, and I'm
going to get burned for it, so I will make this short.
I just wish that the porting of (already existing) drivers had been
finished before RH decided to make XF86 4 a part of the standard install.
Now a machine that has run X for a couple of years can't do it anymore. I
need to check and see if this card will be supported in later times (Many
thanks for the link, by the way), but for now I will have to revert to an
older version (hope my libs don't conflict ...)
Best Regards,
Robert

mingetty is the program which sits on the consoles ( by default 6 of
them-- accessible by alt-ctrl-F1 to Alt-ctrl-F6) waiting for you to type
in your name to the login prompt. No mingetty, no login.
So, why do you want to get rid of mingetty? Maybe you want to get rid of
init as well? Ie, some things are crucial to the proper running of the
computer, and you do not want to get rid of them.
Note that if you really want to get rid of them, go to
/etc/inittab, and comment out the lines where they are started.

try to mount /home if you can.
Once you can issue something similar to below:
# # copy the /home directory to another hard disk
# cp -a /home /some_nice_safe_place/home.backup
# # or make a tar ball and copy the tar ball to CD-RW, tape, hard disk,
etc.
# tar cvf home.backup.tar /home
If you can't still recover /home, you might try the following
# # the /home is on /dev/hda1
# fsck /dev/hda1
If you still cannot recover, I think you are screwed .

Uh, You should learn what the various lines in inittab do befor changing
them. mingetty and vgetty are entirely different programs. mingetty
listens for input ( and displays /etc/issue) on the consoles. If you
have nothing listening on the consoles, you cannot speak to your
computer!

It starts. It just does not sit there waiting for you to log in to any
of the consoles. That is the purpose of mingetty.

alt ctrl del
Then do
linux 1
at the lilo prompt. This should dump you into a root shell.
Then edit /etc/inittab and restore those mingetty lines!!
