I've also seen this, it is caused by Suns/Solaris machines not failing

Linux at this time (I think).
I've had to set a 'vers=2' option on the fstab or automounter map to fix
this. If you have both linux machines, and SunOS machines on the same
map this won't work since mount of Linux doesn't know 'vers=2' instead
'nfsvers=2'

OK, I think I see what you mean now !
For the benefit of readers who did not receive an Email from M.
Goddard, the "network emulators" are boxes designed to add delay,
and errors into the transmission line.
Yes, You might do this with only two PC'c but I think it will be
easier with three.
If you have two NIC cards in the central PC, and enable IP forwarding,
so the two network segments can "see" each other,this should do what
you want. This is an option when recompiling the kernel. You will not
need any further software.
Unfortunately this is where my knowledge ends. I have never set up a
Linux system with two network cards, although I know this is possible,
It just isn't necessary on my home network.
Perhaps someone more expert can enlighten us here. :-0

To use VNC you need an almost complete X install. You need everything
except the server as VNC supplies the server. I would go ahead and
install the correct server for your video to make sure everything was

Hello,
You can *try* the following:
Type:
/etc/rc.d/init.d/atalk.init stop <return>
then restart the servers, and look at what appears on your screen:
/etc/rc.d/init.d/atalk.init start <return>
When I did this on my Linux server, I had a message saying that Net(0)
was not within the range... something. The problem was due to the
atalkd.conf guessed by netatalk. I have two network cards, and I had to
remove eth1 from this configuration file.
This file is located at /usr/local/atalk/etc/atalkd.conf
On my actual system, it contains now a single line:
eth0 -phase 2 -net 0-65534 -addr 65280.158
...but I had to manually remove the second line, starting with eth1.
I'm not sure it will help you, but I hope so!
Good luck

I am set up with Red Hat 6.0, kernel 2.2.5-15 and pppd 2.7. I am using the
demand option with pppd and everything works pretty well.
In addition to what was mentioned, I have these additional options for pppd:
icpc-accept-local
icpc-accept-remote
10.0.0.1 : 10.0.0.1 # these are bogus remote/local addresses to force pppd
to get them from ISP
Also, for my setup, the file /etc/sysconfig/network-scripts/ifcfg-ppp0
contains most of the real settings used.

Subject: TCP/IP problem
Date: Wed, 21 Jul 1999 15:39:15 GMT
Reply-To: [EMAIL PROTECTED]
To replay to my e-mail, please remove NOSPAM.
I have a problem with my networking and RedHat 6.0.
Let me give a breakdown of my hardware. Asus P2B-F, Int PII450, ATI
Rage Fury, Netgear 10/100 PCI, SB Live!, 128MB, 20GB HD.
My problem is that I cannot telnet to my machine, either from the
machine or over the network. I can, however, telnet to the loopback
address. The same problem exists with ftp. I can ping, traceroute,
etc. and can ping the IP address (192.168.1.3 if that helps, not that it
should matter).
I recompiled the kernel (2.2.5-15) and made sure that I only had the
driver for the DEC Tulip card selected. When it boots, eth0 reports
OK. ifconfig gives ?proper? information (UP BROADCAST RUNNING MULTICAST
...).
This also leads me to believe that this same problem is occuring with my
PPP connection.
Any help would be appreciated

Subject: Most hosts are reachable, some aren't...
Date: Wed, 21 Jul 1999 16:03:57 GMT
Hi,
I have a Linux box with two interfaces: one to a local network via an
Ethernet card and the other to my ISP via PPP (ISDN).
A very simple firewall setup using ipchains (and masquerading) is running:
everything is open.
Everything works fine except that a few hosts (outside the network) are
unreachable via a browser from the firewall-machine and the network. All
these unreachable hosts have in common that they don't answer on ping
requests. These hosts *are* reachable from machines not in this network
(but still not via ping, though).
An example of such a host is: www.kennisnet.nl.
I hope someone might be able to help.
Thanks,
Thomer

If this is a standard serial port on a standard irq, this should work
(ie. ttyS[01] on irq[43]). Do a dmesg and see if the ports are reported
properly.
Is this a persistent slow modem, or does it work well and then pause?
Any hope you have a nice external modem with hardware lights? Does you
pppstat and/or ifconfig indicate errors?
You have to know if the cause is errors before you can move forward. If
you have errors and always slow response you probably have a config
issue (or remotely possibly hardware), while the occasional big pause is
frequently caused by a missed ACK followed by a timeout and duplicate
packet. If that's the case, tcpdump may be able to give some info, but a
solution is not always at hand.

All uppercase? That I wasn't aware of; I'll have to give that a try.
The logged messages are basically worthless. I get two messages saying dhcp

Hi,
I have a problem running telnet deamon (in.telnetd) on a Linux system
based on Small Linux.
While ftp workes fine, I get the following answer when I try telnet:
Trying 127.0.0.1
Connected to homegate
Escape character is '^]'.
telnetd: All network ports in use.
Connection closed by foreign host.
Is there someone who might know the anser to this problem?
Here is some more information about my system:
As I said before, I took Small Linux as the basis for my installation.
Then I added
network support and inetd by hand. Within inetd.conf the following lines
are enabled:
ftp stream tcp nowait root /usr/sbin/in.ftpd in.ftpd
telnet stream tcp nowait root /usr/sbin/in.telnetd
in.telnetd
shell stream tcp nowait root /usr/sbin/in.rshd in.rshd
-L
login stream tcp nowait root /usr/sbin/in.rlogind
in.rlogind
I do not have much experience with Linux and therefore I do not know how
to handle this problem.
I would be very grateful for some helping tips...

Not exactly...
IP forwarding will not split the TCP connection :
TCP TCP
| |
IP IP <--> IP IP
| | | |
PHY <--------> PHY PHY <---------> PHY
You will still have a end to end TCP connection, because IP just forward
the packets (like a router on the internet)
