Hello all.
I figure this is probably a very simple newbie question, but after looking for
the answer on the web for 2 hours and not finding anything close, I'm hoping
somebody here could at least point me in the right direction.
Problem, I have to chmod my web dir to 777 in order for my CGI scripts to be
able to access it. How can I assign "effective user ID" to scripts run from
the cgi-bin dir?
Thanks in advance for your help,
Erik

All,
I have gone around and around the IRQ issue for years now and I keep
reading and seeing different answers to the same question: The PC
architecture allows for eight expansion slots but has a very limited
number of IRQs free. Once you take out the real time clock IRQ, the
serial lines (COM 1 and 2), keyboard, cascade, two for IDE and the
parallel printer, along with a modem, the diaplay adaptor, sound card,
games controller and the floppy disk (etc - get the pciture?), you're
normally left with, at best, IRQs 10, 11, 12 and maybe 6 or 7.
If you then want to add a scanner (SCSI card), network card and, as I
have, and ISDN card - well, you're suddenly out of IRQs and added to
this, you have to fight with PnP on PCI which, it seems, we have no
control over. So you end up juggling IRQs with ISA cards using the pnp
tools for Linux and trying to force the PCI card settings into something
sensible by juggling the BIOS settings.
All of which is background for the gurus out there to pull apart and
comment on. The number one question though is: Can you make more than
one device share an IRQ?
I tried to make my soundblaster card share IRQ5 with my 3COM network
card on the grounds that I seldom use sound but my entwork card is
always active - no go! I lost sound altogether. Move the network to
IRQ10 and all is happy, except that IRQ10 is also my SCSI card. Now it
MAY be that my SCSI card isn't installed properly, by suspiciously, my
scanner stopped working.
The evidence points to not being able to share IRQs, in which case I am
stuck because there are no free IRQs on my system. However, reading
through postings, looking at websites and reading book tends to point to
the opposite conclusion: You can share IRQs but it's a bad idea to share
an IRQ between two very active devices.
So, what is the correct, definitive answer to this issue? Is the PC IRQ
system a caring, sharing environment, or, like the raptors in Jurassic
Park, does a single device kill anything trying to share its turf (IRQ)
that isn't its own?

No you don't. Look again. You only want read/exec permission on your script
dir. And what do you mean by "your"? If it's /var/httpd/cgi-bin, then
it's not yours, it's the system's.
If you want your scripts to write somewhere (they shouldn't), then make
sure that directory is in a place that can do no harm, and is DIFFERENT
from your script dir. That (the latter) directory may have write
permission for the user you are running httpd as. Or you may use suid
(sripts yet, with sperl or suidexec) executables to allow you to write
where you need to.

You don't (although you can). Reexamine your hypotheses.

Hello there.
I'm in need of the following utilities (open-source preferred), but it must
be freely available.
I need a uptime monitor, for monitoring machine uptime, or, actually
preferred network device (e.g. eth0) uptime. Or network programs, e.g. inetd
or rpc.portmap uptime.
Any such thing available?
Oh yeah, running custom-built Linux.

ever tried another port ,
like f.i. /dev/modem or /dev/ttyS1?
or even try to switch mouse ( i guess is on serial1(ttys0)) and modem?
modem would then be /dev/ttyS0 and mouse /dev/ttyS1.

If you are not a "babysitter" how come you post a reply at all?
I think that rude replies are not called for, we are not all experts
or are you offended by my referral to normally using Windows?
I just asked a question (notice the word "please"?) and anyone
answering should do that on their own accord in order to help those
not so fortunate as to be experts in the field. I also hinted that the
man pages were in fact uneadable due to the way Telnet displays them
(text on top of text with no screen erasure in between).

I think you'll have to put lilo on the floppy disk, instead of just
dumping the kernel onto the floppy. Then you can have a lilo append line
with "mem=128M".
: - the root file system is on NFS. So I can't create a swap file (on

Swapping over nfs is not supported by the linux kernel, but there are
usually some patches on the web to allow you to do this.

No, I'm offended by your apparantly sitting on your patsy and complaining
that you need to be spoonfed at the same time.

Set your terminal type to vt100. Or set your windows emulator to emulate
vt100. At any rate, make sure they agree. "export TERM=vt100" is the
simplest likely cure. If you don't tell me what types your windows
emulator supports, I can't guess.
Your problem is that you cannot see, and not being able to see renders
you unable to read. But even then I would have expected a
resourceful person like you would have tried
man foo > /tmp/foo
less /tmp/foo
and hit ^L every so often. Keep trying.
So this is your problem, then? Not the stuff about timezones?

I am a poor Windows user with a Linux machine running as a test bed
for web development so I am not real versed in how all these command
line commands should be typed. Please be specific in your advice.
Please sit down at the console of your linux machine. The man pages

I have recently found the "WWW Collector Prefetching Proxy Server" software,

But I'm having trouble getting it to compile. (Well, I should have known,

I just went through this, and it is confusing. First of all, there are
two clocks: the hardware clock (which is the PC battery backed up
clock) and teh system clock. Linux only uses the hardware clock at boot
to set the system clock; then ignores it. Setting hwclock makes to
difference to linux until you reboot.
So:
date --set time <- to set the system clock
hwclock --utc --systohc <- to set the hardware clock
make sure the file /etc/sysconfig/clock includes the line
UTC=true <- this works for RedHat, YMMV
and make sure the timezone is correct and you should be all set at the
next reboot.
Also look up www.ntp.org if you really want accurate time.

NO. If -9 does not kill a process, then your system is dead.
The process is in uninterruptible sleep in the kernel, or
otherwise occupied.
I'd guess you have a funny file system. Possibly a full one too.
