Question: Running M-x gnus in emacs is locking up emacs! I've never seen such

Any advice? I've used gnus before and would love to be running it now. Tia.

I'm assuming that you want to share an internet connection here...
if that is true, than what you want to do is setup IP Masqurading, and get
the newest IP chains software. There are various HOWTOs out there on
setting it up. You can get IPchains off of www.freshmeat.net.
Also you should probably grab masqdialer. Masqdialer will let you dial the
modem on your Linux box from any other computer on your network. There are
clients for masqdialer for just about every OS out there...it's pretty
easy to set up too. Again you can get masqdialer off of www.freshmeat.net.
Just use the search engine at the top of the page...if you have any
questions, feel free to email me.

Subject: Can't see server until server sees me
Date: 28 May 1999 04:03:15 GMT
I have an ethernet network of Windows clients and a Linux (Red Hat 5.2) server,
plus another RH5.2 machine. All the machines can ping each other, except none
can ping the server until the server pings them. I've set a script running to
ping each machine in turn, since after some time period of inactivity, the
server can't be pinged again. Is there something running on the server that
might be causing this?

Subject: Linux 2.2 IP Masquerading
Date: Thu, 27 May 1999 15:18:28 +0100
Hi,
I want to set up a linux box to masquerade for a network. There will be
two modems, with different IP addresses. I can set up the routing table
so that some of the traffic is routed through the first modem and the
default for the rest of the traffic is routed through the second modem.
I want to IP Masquerade both these interfaces, but I can't find and
documentation saying how this will work.
All the docs imply that masqueraded packets are given a new source
address of the computer doing it, but as we all know, IP addresses
belong to interfaces, not computers. Do all masqueraded packets get
given the IP address connected to the default route (as the docs seem to
imply), or are they given the IP address of the particular interface
they are routed through. I'm asking before I've had a chance to test it
because I want to get all the theory worked out before I start.
I hope this makes sense.
Thanks for any help,
Amir Shamsuddin

I am having no luck on getting ftpd and telnetd working correctly.
I hope someone may shed some light for me.
Quick overview:
I have 2 pc one for Linux and one with win98 connect via network
I am able to ping either way
If i set up a ftpserver on the win98 machine I have no problems.
When I http to the linux box -- no problem at all everthing work fast and
great.
When I try to ftp to the linux box -- no luck
When I try to telnet to the linux box it takes about 5 minutes to get a
login prompt.
I have been reading man pages, book after book. I have yet to find a great
referance manual describing the configurations of possiblties of linux
I have filtered through the syslog called messages, which leaves me with
even more questions. Where are a few lines that seam to be pertinent to
the above problems and a few line about lp1

Subject: Re: SAMBA & Win95 Logon authentication
Hi James.
Based on my recent experiences setting up SAMBA on a RHL 6.0 box, I'd
like to offer the following:
1) How are you starting the smb and nbd services? Are you adding the required line in
netd.conf or are you starting the services manually?
2) It may be wise to not attempt the full-blown 'NT Domain' thing until after you get
a basic 'user' or 'share' level setup working.
3) Which version of Win95 are you using? Certain OSR2 distributions require the use of
encrypted passwords.
4) What SAMBA version / LINUX distribution are you using?
Hope I can help you get it working.

Hi
I think in the ifcfg-eth0 script (or whichever interface is connected to the
adsl line) the BOOTPROTO should be "dhcp" if you want to use DHCP for the
interface.

Subject: NIS timeouts under heavy load?
Date: Fri, 28 May 1999 04:44:59 GMT
Reply-To: [EMAIL PROTECTED]
I'm running into an NIS related problem on a RedHat LINUX 5.2 network.
The network has one NIS master which services 64 workstations
connected together as a cluster. The problem is that when there is
heavy network activity among the cluster nodes, we get these error
messages from the clients:
node01: yp_all: clnt_call: RPC: Unable to receive; errno = Connection
reset by peer
It seems as if the NIS server is not able to respond to queries fast
enough or something. We usually get these errors when all 64 nodes
are making network connections either at the same time, or one right
after the other. Does anyone know what this error means and how to
address it? Your help would be deeply appreciated as it is causing us
many problems. Thank-you.
We are using the ypserv/ypbind that came with RedHat 5.2:
ypbind version 3.3-glibc3
ypserv - NYS YP Server version 1.3.5 (with tcp wrapper)

Subject: No loopback adapter, or neighbor table overflow
Date: Fri, 28 May 1999 04:54:08 GMT
Hello! I seem to have a problem with my PCMCIA nic and redhat 6.0. When
I start my machine at work, where it is connected to the network, and is
a server there, it runs just fine. When I have the network cable
disconnected, or when I have it plugged into a different network at
home, I get neighbor table overflows. I can boot if I take the nic out,
but if I put it back into the machine at home, it begins giving me
errors. Something that may or may not be related. When I start the
machine at work, it does NOT automatically start the loopback adapter.
I have to start it manually. However, when I remove the NIC from the
machine and boot it, the lo adapter starts. Anybody have any ideas?
