Sorry! Remove rrdhcpcd to rrlogind for the first set. I moved these so
that when I rebooted the server I could still telnet to it before it
tried to access the roadrunner network.

Hi all, I am having problem installing the dhcp-0.70 into my RH 5.2 box. I
just reinstalled the OS from scratch and retry and it still have the same
problem. There isn't any thing from the DHCP how to to deal with the
installation. I need dhcp to work with the cable modem from @home. Please
help.. Thanks in advance....

Hi,
I remember many months ago there was a freely available realaudio encoder
and streamer that worked for Linux. Now I can't find it again so I want
to try and find another solution -- is there an alternative I can use?
I'm looking for something that could stream mp3s from a Linux server.
that would work with a Windows 98/NT client.
Is there such a thing available?

Are the drivers for the Etherlink III (3c900B-TPO) compiled in the kernel
that is included with Redhat 5.1? Yes, I'm very much a newbie, but I went
out and bought this ethernet card and now it doesn't seem to want to work.
Thanks!

Had the same problem...
According to a mini-faq I found @ linux.org, Linux probably doesn't like the
plug-and-play features of your card. Get the setup program, if you don't have
it already, and disable the plug-and-play. Linux should be able to recognize
the device. However, Windows may need to install ISA drivers for your card
after you boot into Windows the first time after that. After this, Windows
and Linux should be able to use the Ethernet card in harmony.

Hello,
When configuring the network portion of Linux make sure that you make the

proxy on the linux box..i have had this working for a year with proxy 2.0

Hello Stephen,
I am assuming you are using Netscape, if the assumption is correct , using
edit, preferences, advanced, set up your proxy settings using the IP address
instead of the proxy server name then set the port to 80. Possibly the DNS
is not set up correctly and is not recognizing the server name.
Of course ping the NT server with the proxy server from the linux box, you
must get a response. It should work with either MS Proxy, or Wingate proxy,
whichever one you are using.
Let me know if this solves your problem,
Thanks,
Louis.

Hi there,
since I upgraded our server I noticed the following error/warning
message in the syslog:
kernel: <ip-addr> sent an invalid ICMP error to a broadcast
I'm pretty sure that I haven't seen it before the upgrade.
Am I correct if I assume that this is a problem with the machine
<ip-addr>, and that kernel 2.2.x is a little bit more "offensive"
about what it reports compared to 2.0.x? Or is it a problem with my
machine (which I doubt)?
Thanks,
