Buggy BIOS.

Just add the line
  append="mem=512M"
to the general section of /etc/lilo.conf, run lilo, and reboot.

I'm currently the sr. developer at a small company in the manufacturing
field. All of their systems right now run on that other OS (ok, a mix of
them). I'm slowly but surely trying to make converts out of them. My current
pet project is to implement a linux-based system for monitoring our database
and file servers (a bunch of them). Namely, I'm working on something
rule-based. For example, I need to poll the MS SQL (7 and/or 2000) server at
a set interval. If the machine is up, but the service isnt, try to start it,
if it doesnt start, try to reboot the box and start it, if it doesnt come
back up 5 min after the boot, page this person and this person. Something
like that. Basically, I've gotten as far as monitoring if the boxen are up
(ping is my friend). My question is, how can I control SQL Service activity,
reboot the NT servers remotely, etc. from linux.

And on an unrelated note, maybe someone knows, how can I intelligently
(automagically) determine if the problem is with the box or with the
network?

Thanks in advance for all the help, and yes, the source will be open.

Take a look at NOCOL. For specific types of server, you can build (eg) perl
or C programs to access the servers remotely and (combined with PING type
checks) you can tell if the server itself is down or if the machine/network
is buggered.

i *think* that there is something in a book called Advanced Unix
Programming  Marc Rochkind / Paperback
/ Published 1985. He details some C code to do this, you use system calls
to modify the setup of the terminal, Sorry I can't remember any more
details but it has been a few years since I saw it.

Also, doesn't the kernel compile use the -pipe option
to gcc?  That would already give some parallelism
even without the -j option to make.

sorry that I come back on this, but I checked moc more closely.  Conclusion:

moc (Qt-1.43) compiles well and does not have the "defects" make-3.77 suffers from.  
Anyway moc
crashes, for instance:

in qt-1.43/src:

$ gdb ../bin/moc
...
(gdb) run dialogs/qfiledialog.h -o dialogs/moc_qfiledialog.cpp
...
Program received signal SIGSEGV, Segmentation fault.
0x400ca291 in _IO_unbuffer_write () at genops.c:734
734   _IO_SETBUF (fp, NULL, 0);
(gdb) bt
#0  0x400ca291 in _IO_unbuffer_write () at genops.c:734
#1  0x400ca2c9 in _IO_cleanup () at genops.c:749
#2  0x40095029 in exit (status=0) at exit.c:62
#3  0x4008caa1 in __libc_start_main () at ../sysdeps/generic/libc-start.c:78

Similar results for moc from Qt-1.40 when recompiled with glibc-2.1 and egcs-1.1.1 
(which worked
well with glibc-2.0.6 and gcc-2.8.1)

And now?
