I'd suggest checking rpmfind for the 'ircd' package (the libc6 contribs
package (2.10.3) is probably appropriate for RH5.2).
If not, you can always get the sources from ftp.irc.org and compile it
yourself. Note that unless you link your box to one of the IRC networks
(and you need high capacity and high uptime to do that), your users will
only be able to chat amongst themselves.

thanks, Eric!
I forgot to mention that I'm booting from the boot record in the old HD
and once the boot is completed the new HD works perfectly!
from my reading of the NGs I learned that there is a good chance that
the problem is the BIOS not recognizing the HDs correctly; here's what
was detected; does it look ok?
/dev/hda /dev/hdc

Wrong again !!!!
I generally know what kit my clients have installed, and they generally
know what I have.
This may well be true for the bulk of non spam BLOB emailing. It's the
sort of thing that tests to get established quite early in any
electronic relationship.

I have to piggyback here, since I don't have the original poster
available. I have a Creative Labs DE5625 external modem-afaik it is a
true external modem that is totally hardware based. In other words, it
doesn't care what OS you're using it under. That being said, let me also
note that the DE5625 is a real piece of trash, not worth the money I paid
for it. I never got a connect faster that 34K with it-typically it would
connect at 32~33K at best (sometimes even 14.4K!). It also didn't matter
what OS I used it under-it sucked equally under Windows NT, Slackware, and
FreeBSD. I spent two weeks monkeying with init strings and port speeds,
and finally threw it in the scrap box. I ended up getting a (new) Hayes
V92 Accura in it's place-much nicer and connects no slower than 48K. The
DE5625 may work well in a clean environment with little line noise and a
short line run to the ISP, but in the real world forget it.
The original poster has a crap modem. Ditch it and pay the bucks to get a
better one. Not all external modems are equal, and sometimes you get what
you pay for.

I would think twice before doing this. How do you propose to get his
ISP's IP address? I get port scans and stuff from crackers who forge
the source addresses. It would not be fair to the owner of the forged
address to do things like that. The particular pest that scans me uses
addresses on my LAN as the source address; i.e., he uses addresses
such as 192.168.1.xxx, where he changes xxx for each batch of
attempts.
So if I did that to him, I would just forward the stuff to stations on
my LAN. I am surprised this cracker never tried some of the more
likely addresses on my LAN, so he never actually picked one of the
addresses that actually exist. He is pretty stupid, tough. Here are
two of his (denied) attempts:
Mar 5 10:28:28 valinux kernel: Packet log: input DENY ppp0 PROTO=6
192.168.1.16:80 208.225.67.131:4009 L=40 S=0x00 I=33758 F=0x4000 T=118

(#2)
The cracker is probably a dumb script kiddie. I do not accept source
addresses through my ppp (Internet) connections that have my LAN
addresses, and I accept from my eth (LAN) connections only source
addresses from my LAN.

I just put mine in last night with no problems detected. I installed
db3 packages first, then the rpm and popt together.
The instructions from Red Hat for installing db3 seem incorrect for
version 6.2 of Red Hat Linux 6.2. They say to do rpm -Fvh db3*, but
this will not work, because RHL 6.2 does not have db3 installed, so
you cannot freshen it. I used rpm -Uvh db3* to make it go in.

Subject: powersave
Hello,
I was wondering if any of you people have come up
with this problem (feature ??) :
I also asked comp.os.linux.x but got no reply.
After ten minutes of inactivity, my screen
goes blank big time. This means that the monitor
switches itself off. If I move the mouse or
punch a key on my keyboard , it comes back.
Extremely frustrating :-)
Config :
Compaq Deskpro EP PII 350, 128 Mb ram.
Mandrake 7.2 with xfce and X 4.0.1
Checked :
- /etc/X11/XF86Config - powersave was there.
Remarked it - no change
- xfce newsgroup. No problems there. Xfce does
not interfere with X
- Kernel (2.2.18 btw), apm is switched off
- System BIOS - apm is switched off
Any ideas , anyone ?
Thanks in advance.

Hello again,
I'm having a problem with the xwc file manager- now I can only use it as
root. (has been working just fine before this) I tried uninstalling,
logging out, reinstalling, logging out -- but still situation is the same.
Removed an alias I had created in .bashrc thinking it might have something
to do with it- still no go. Tried changing the ownership to user, then even
tried changing it to -r-w-x by all-- no help.
I have recently installing the sun 1.3 java sdk and several java ide's--
can't think of anything else I might have done.
All other file manager working as expected but I prefer xwc.
Running Gnome,Mandrake 7.2, sawfish.
Pent 11 400mghz 128 ram.
Any suggestions of where to look for possible answers?
many thanks,

IPChains can do the same, there is a REDIRECT target, where you can
redirect packets. See ipchains man page or the ipchains HOWTO.

That sounds reasonable, but wouldn't setting up ip spoofing protection
(this is for 2.2.x)
for f in /proc/sys/net/ipv4/conf/*/rp_filter; do echo 1 > $f; done
prevent that the kernel mirrors to your own/others network?

I have just noticed that most library packages, generated with libtools,
produces library files as libxyz.so.[versions], libxyz.la, and libxyz.a.
It looks to me that the libxyz.la has the information for the linker as to
where and what the shared library libxyz.so is, am I correct? If so, the
libxyz.la should be part of the libxyz.so.[versions] as a package for a
distribution, i.e. rpm or deb. Does anyone know what other significant
uses does a libxyz.la have to do with its counterparts: libxyz.so and/or
libxyz.a?
