I'll just take a wild guess here: if these daemons are involved with
licensing management, they may be communicating via the internet to
the "mother ship" as it were: some company's web site or whatever..
If they're communicating, they're opening a port on your machine via
its current IP address; if a cracker knew what IP and port, bingo!
you've got a potential major security hole, made worse by the fact
that their daemons can be run as root.
Thus the suggestion that you *not* run 'em as root.
It would be interesting to say:
"tcpdump -vv -i [whatever_your_exterior_interface]"
and watch what/how often they're communicating.
Again, this is a wild guess..

telnetd is managed by xinetd in RH7 (inetd in older versions). xinetd is
running and when a telnet request comes in, it starts in.telnetd, which handles
the connection. Look in /etc/xinetd.d. I think the telnet server is not enabled
by default in RH7, but if it is, put
disable = yes
in /etc/xinetd.d/telnet. You might as well uninstall the telnet-server rpm
alltogether. Similarly for other daemons managed by xinetd.

Hello everyone,
I just compiled a new 2.4.2 kernel and I'm having some difficulty setting
up the modules correctly. For some reason my modules.dep file in
/lib/modules/2.4.2 is empty. I've made kernels before and this never
happened before.
The steps i did were
=> make mrproper
=> make menuconfig
=> make bzImage
=> make modules
=> make modules_install
and the modules are in /lib/modules/2.4.2, it's just that that modules.dep
is blank. Is there a quick way to generate this file? I tried making the
modules and then installing them again but it's still blank.
thanks

I just dled the personal of SUSE 7.0 ISo's and they go on 4 CD's.... I
use a bootdisk to run install. I have an 800mhz AMD, with 256megs of ram,
and when i try to install.... when i put in the first CD, it starts
loading.... puts all the info into the Ramdisk.... then the scrolling block
goes to the next line and just blinks.... I pressed after a while Alt+F4 and
it started Scrolling (Kmod: failed to exec /sbin/modprob -s -k binfmt -464,
noerror=8)
i was wondering if anyone knew why Suse won't install into my computer....
and it was off a mirror of SUSE.com.. thx if you would help me..
I've got an Asus7 motherboard,a USB logitech mouse, and as you saw enough ram
for it to load into ram... i used YAst2 for the install.. and the other one i
not sure what the name of it was.... so thx if you could help :)

Well, that's an option someone else came up with when they ran in to the
exact same problem getting TurboLinux 6.0.2 to run on their machine,
which I also can reproduce. he solved it by turning off the Level 1
cache through the CMOS; unfortunately, I don't have that option in my
Dell BIOS settings.

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

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

You can't. That's not a kernel compiler (not a compiler worth anything
..). Get gcc 2.7.2 or 2.8.1 or 2.9.5 and compile the kernel.

This definition is way to simple.
DDNS stands for Dynamic Domain Name Service and is an IETF activity.
MS once did a 'hack' that connected their propetary WINS stuff with their
propetary alterated version of DNS. It happened to be (partly)acceccible from
teh "real" dns world.
The possibility to update a DNS server with DNS messages has been around
since bind-8.2 It has not been widley used becouse of it's security effects
( om meybe better - lack of security ).
With w2k ms had ditched WINS amd uses DNS as transporter of Active Directory,
and subsequently has a version of a nameserver. It seems to cooperate with
IETF standards on most issuses, but it also uses undocumented features
that makes life wuth AD more bearable. Those features is not compatible
with the IETF standards we know as DNS.

Hi,
The FA311s are totally different cards to the 310s. Whilst the 310s
are based on Digital/Tulip 21041 chips the FA311/312 cards use National
Semiconductor DP83815.
Source: http://www.openbsd.org/i386.html
I've no idea if the 311s will work in Linux or not, although my 310 did

If this is the same error message each time, then it appears to be a
compiler error (or malformed source file). Try again with -O1 on that file.
Try with egcs 2.91.66, which I think (frm memory) is the approved 2.4
compiler. If no joy and the file is OK, then it is a coding error in
the source.
And try leaving out a.out bin support. Surely you don't need it!

you don't need any modules loaded, at least not with gatos 0.0.4
which video card do you have exactly? Make sure your tv tuner is
