I've got a Redhat 5.2 (2.0.36) box up and running doing dialup net
access for our network running IP Masquerade. Finally got all the bugs
worked out, but now I'd like some way to capture what machine on our
local network (192.168.1.x) caused the Linux box to dial out, and
perferably what IP it requested.
I'm using /usr/sbin/request-route to bring up the PPP link. From this
I can get the destination address which caused the link to come up, but
I have no way to find the originating address.
Using tcpdump I can see exactly what I need, but I would rather have
something which just logs the originator/request. I've seen this
feature on 3Com OfficeConnect ISDN routers, which our Linux box
replaced. <grin>

Is there an appropriate route configured for eth1? If not, your ping for the
network hanging off eth1 may be going through the default route on eth0.

Subject: Amd broken under RH6.0
Date: 28 Jul 1999 03:52:16 GMT
Under RH6.0, I see a problem when automounting a large directory on
an HPUX machine. The first access "ls /net/jr" gives a full directory
listing. The second access shows a null directory and there is the
following error in /var/log/messages:
jr:/ mounted fstype host on /.automount/jr/root
NFS: server jr, readdir reply truncated
NFS: nr=46, slots=0, len=4
I've grep'ed all the howtos and scoured deja news, and have found other
people with the same problem, but no answers yet.
Does anyone know where there is some info on amd? Is there a maintainer,
a web page, or a FAQ? Is this a known problem?
kind regards,

Subject: Kernel 2.2.9 - poor network performance under low load
Date: 28 Jul 1999 05:10:50 GMT
Howdy,
I've got 2 machines, a P200/64MB server with a Realtek PCI NE2000 clone, and a
PII300/160MB workstation with a 3COM 3c905. The server runs RedHat 6.0, the
workstation Slackware 4.0. Both have 2.2.9 kernels, the server is
configured to be a firewalling router, so it has optimizations such as IP
Defragmentation compiled in.
The problem is this: in circumstances where there is almost no load, i.e. a
single telnet session, a ping from the server to the workstation, downloading a
file from the server, the network will hang for several seconds before sending
what seems to be the last packet in a series. For instance, when I telnet
over, there are times when my last keystroke does not appear for a few
seconds, or until I type another key or two. Pings often spike up to 1000ms
for a single packet, then back down to normal. Exception: when pinging from
workstation to server, pings are low and continuous.
The interesting part is, the problem goes away as the network load increases.
If I start 2 ping sessions, the spikes aren't as bad. if I run a kernel
compile in one telnet session, my other session is smooth, with no lag. It
seems that as long as there's a steady stream between the two machines,
everything runs fine; it's when packet transmissions are sporadic that the
problems begin. It is as if the server is caching packets, or that the IP
Defragmentation routine is waiting for some non-existent fragments to arrive.
Or else I've got some goofy hardware that coincidentally went haywire as I was
upgrading the server.
Prior to upgrade, the server was a RedHat 5.2 machine running 2.0.36 without
these problems. There was an intermediate step where it ran 2.2.9 with these
exact problems. Kernel 2.2.5 gives me the same behavior.
Thanks in advance for any assistance.
Regards,
Dave Del Signore

Make sure you insmod in this order:
pcmcia_core.o
<your chipset> i***.o or tcic.o
ds.o
then run cardmgr
if that doesn't work then download the latest pcmcia modules, if you
have done then go into the source dir, then into /cardmgr and run
./probe, if it picks up your card slots, then something else must be up.
But try what I've suggested first anyway :)

Subject: NIC works! Now what?
Date: 27 Jul 1999 23:04:29 PDT
Hello again. I tried swapping out my old NIC for a new one; that solved the
problem with pinging. My network is now networked. Only...
Each machine can ping the other. But something's not quite right. When I
ping from the Linux box, I can use the nickname or alias I gave the PC.
When I ping from the PC, it'll recognize the IP address, but won't ping the
nickname of the Linux box. The nicknames are listed in the C:/Windows/Hosts
and LMHosts files on the Wintel box, but this doesn't help. Any ideas on
this one? Thanks!

Reply-To: [EMAIL PROTECTED]
First of all, I am not spamming. what I am writing to tell
some of the others on this new group is... If you are looking for a
good quality inexpensive 4 port serial port that shares interrupts as
well as has the ability to set the onbourd timer to run your 16550An
serial ports to 480kbps on an isa bus, this card will do it. it
supports IRQs 3,4,5,9,10,11,12,15 you can even set each port on its
own irq if you want.
When I got the card today I almost lost my cookies. Golly Gee!
a REAL honest to god manual! Yes its small but the card has more
options that I can even think of. (hint, if you are gutzy. you could
probally have 4 or more of em in one machine! one to act as the normal
com1-com4, and YES the interupts for Com 1,3 and 2,4 DO work like they
should. then a second card for Com-5-8, a third card for addresses
0x100-0x11F and possibly two more if you can spare the slots! I am
going to order two more ;)
First time I got it. I thought it was AST fourport compatible,
turns out that it is a boca BB-1004/USENET II compatible card. It
supports all standard handshaking in addition to a IRQ status
register. For $50 from Dalco Electronics. this card really makes it
easy for me to plug in lots of terminals here.
In addition you can Map the ports to the 4 serial ports any
way you desire.
If you are interested in Aquiring this beauty. you should be
able to order it from Dalco Electronics's web site of
http://www.dalco.com item number is 61505. They were backordered and I
had to wait 1 month for mine. Aparently because of Linux they cannot
keep enough in stock! ;)
If you rather call and order it. the catalog phone number is
1-800-445-5342
P.S if anyone has any objections to this summary. please do feel free
to contact me. If you would like more info on how well this card
actually works. email me too.

Thanks for this Jim.
I discovered that on RedHat this file is called /etc/conf.modules but
has the same syntax so I've put the aliases in there.
I suppose I'll need to reboot the machine to take effect (probably
overkill ... )

You would probably want it to read:

(I can't say that I have ever had to edit this file under linux though). Don't
worry about nis or nisplus (unless you're using either of them).
I haven't had a chance to test this yet.

In linuxconf there is a setting for:

And I belive '[*] Enabled' take the nic up at boot. (I use lilo, but
that demand driver in kernel)

If you boot up and do a '/sbin/ifup eth0' does it work?
Or do you need to load the module? (insmod something)
If it can be done that way, maybe put it in /etc/rc.d/rc.local

Maybe turn off 'boot with pnp-os' in bios and set the irq chosen for
the nic to 'legacy isa'. What irq? (irq 3 and com2 on irq 3 as well?)
(irq 10 - I/O 0x300, very common.)
Is it loaded with the irq and I/O value set in linuxconf
(/etc/conf.modules) ?
