Make sure that driver has been fixed. We have SBC'S with the same
chip on it. There were driver problems. But we were trying to run
WinCE on it. Don't hate me for that.
We changed out the chip to the 10Mbps version (I don't have the number
on me) until the bugs get ironed out.
AFAIK, there was some problem running the 8139 even at 10Mbps.
You say you WERE able to run 10M?

The way you describe is essentially what it says to do in:

I'd venture a guess that the packet losses are due to not allocating buffer
space quickly enough. The reason the BSD box doesn't suffer from this problem
is that it pre-allocates mbuf clusters (actually, they're just never destroyed
after they're allocated, but it amounts to the same thing). The packets are
coming quicker than Linux can complete the wmalloc()'s, and so it is dropping
some.
Unfortunately, there's nothing you can do about that. Fortunately, it's a
problem that typically only shows up under very heavy load (Linux normally
has more than ample time to create the necessary buffer structures). If you
absolutely positively need to handle heavy network load, use BSD, because
that's what it's there for (and, IMHO, about the only thing its good for).

Use PAP or CHAP to authenticate. In the PPP secrets file put the IP
address you want to assign to a user in the fourth field of the secrets
line for that user. Example:
UserName * UserSecret xxx.xxx.xxx.xxx
I *think* that's correct, but I haven't actually done it.

I ran into the same problem. You have to have Glibc 2.0.5 in order to
compile dhcpcd. Go to the www.gnu.org website and follow the links. It
takes a few hours to compile/install. It's a little ominous if you've
never done something like that before, but it's worth it.
Then recompile dhcpcd...

Subject: DHCP: Socket: Invalid Option
Date: 11 Mar 1999 15:32:36 GMT
I recently compiled the dhcpcd client/server package, both version 0.70
(since I'm running the 2.0.36 kernel) and the 1.3.17 version. In the
documentation, it mentions that the kernel should be compiled with
SOCK_PACKET. Apparently that wasn't done for mine because when I start
dhcpcd, I get a message in my syslog that says: dhcpStart: socket: Invalid
argument.
I'm using the glibc 2.0.5 libraries (at least, they're installed).
Do I need to recompile my kernel differently? I used the "make
menuconfig" originally, but saw no options for SOCK_PACKET, and I'm not a
very proficient C coder...
Thanks for any assistance

Ok, here's what my present goals are for this Linux machine:
1) Validate user names and passwords
2) Successfully implement the Samba daemon to:
2.a) Create general shares for valid user accounts
2.b) Create shares for private accounting type stuff (a group share)
3) Set-up Apache - I "should" be able to figure out this one...
4) Perform IP masguerading (basically use the machine as a gateway to my
ISP)
5) DNS (both forward & reverse PTR entries)
============================================================================
I am currently trying to log into the machine using "Client for Microsoft
Networks"
I am using both TCP/IP and NetBEUI. My machine will log me into itself
because of the *.pwl file, but it will not log me into the Linux machine.
I have set-up Samba but I don't think it's correct. I can't see it in my
network neighborhood from the 95/98 machines.

Hi
I have two networks I am trying to connect to each other using pppd.
I setup the server side to assign IP's and I have configured the client side
to call. My connection is fine between the two servers, but machines on the
client side can't see past the Linux client gateway. It's as if the linux
(client) box can't route over the ppp0 device. I know the ethernet routing
is fine, because I have two other routers on the clinet side LAN and routing
is fine. If anyone knows how to get the routing working on two lans
connected over a dialup ppp connection. Please let me know.
P.S. Please don't send me simple routing solutions (I have tried all the
possible routing options) it's more of an issue with pppd or arp or
something.

It's definitely not the machine. I've installed a Linux gateway for a
100-computer LAN using a 486dx2/50 and two NE2000 clones and we get
over 400 KB/sec throughput (and that's just what I observe myself, I'm
probably never the only one crossing the gateway).

Hi there,
last year I made a ppp link between two linux hosts, in no time. Now,
I just wanna do the same think and I can't. Could anybody help ?
Originator runs kernel 2.0.34, the other one 2.0.0. Both use ppp
2.2.0. When I call:
- either pppd exists with a message 'serial line is looped back'
after it gets logged through chat. I've checked for existing default
routes, put lcp-max-configure to 50, and so on. No change.
- either it works (mostly when I use an external modem on the calling
side instead of an internal card), but I have around 50% packet loss
when pinging from one side to the other, plus the HDD LED of the
answering machine that gets crazy ...
Don't know what to try else ... any idea ?
Olivier.

I must disagree at certain level. I were ripped of from school two years ago
with no experience and partly because of that haven graduated yet. My job is
programming embedded telecom applications in Solaris environment for
ChorusOS and DMX (company proprietary RT OS) and administration of couple of

John,
This may be a little more complicated than you think. It all depends on how
you have ftpd. In this day and age, ftpd is usually started by inetd. Thus
to turn it off you have to comment out the ftpd line in /etc/inetd.conf and
then restart the inetd server.
If you would like more information, email me directly and I would be more

You can run Netscape remotely. Although, that's an ugly

SCSI is rather more expensive. Plus, there are cable length
restrictions to deal with, especially with SCSI3. Furthermore,
the really dense connectors are a real PITA to deal with.
For a 386 & 486, 10baseT or 100BaseT should be adequate.
However, scsi would likely be a more interesting hack.

The problem is that you defined a net number of 192.168.1.0, with machine
that are with IP adresses 192.168.0.# this means that the machine
send their packets to the default gateway instead of to the local net.
try:
route add -net 192.168.0.0 netmask 255.255.255.0
in each of your machine, to test this solution and if it
works, add/correct your routing table in the network configuration
of the control panel.
