Subject: Errors and discarded packets on a correctly working rtl8139
Date: Tue, 27 Jul 1999 18:34:48 GMT
Hi all. I've just upgraded my RH5.0 linux box to the 2.2.10 kernel and
a brand new ATI AT2500TX 10/100Mbps network card. This card uses the
rtl8139 chipset so I recompiled a minimal kernel --that pc is gonna be
used only as a smb file server-- including support for 8139 and tcp/ip
networking. After successful recompiling of the new kernel and its
modules, I rebooted and got a problem that is ifconfig outputs what
follows:
lo Link encap:Local Loopback
inet addr:127.0.0.1 Bcast:127.255.255.255 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:3924 Metric:1

RX packets:52 errors:0 dropped:0 overruns:0
TX packets:0 errors:7689 dropped:74 overruns:0
Interrupt:11 Base address:0x6100
What seems strange is the fact that the ethernet card is working,
'cause I've attached these lines after having ftp-ed the output of
ifconfig to the Windoze Neanderthal Technology I'm using to post...
Just to give you some more details, I've re-done ifconfig after
ftp-ing this output and got what follows:
lo Link encap:Local Loopback
inet addr:127.0.0.1 Bcast:127.255.255.255 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:3924 Metric:1

RX packets:78 errors:0 dropped:0 overruns:0
TX packets:0 errors:10145 dropped:103 overruns:0
Interrupt:11 Base address:0x6100
Do you have any ideas on what could be my problem?
I suppose it should be a kernel problem, because substituting the Red
Hat 5.0 distribution with a Debian 2.0r3 --that uses a 2.0.34 kernel
with rtl8139 driver added-- makes these errors disappear. I'd like to
know where the problem could be because in another couple of servers
I'm going to install I'd prefer to work with RedHat.
Thanx in advance.

Don't know if you've gotten any feedback on this, but I recently did the
same thing with my home machine. I have four Windows machines and one

then all the Windows machines can get on the Net. I have detailed

I can reproduce that... It goes (almost) like this:
+--------------------+ +----------------+
| | | |
eth0 eth0 eth1 eth0
+------+--------+ +-------+--------+-----+ +-------+-------+
| 192.168.10.2 | | | | | | 192.168.10.10 |
| | | 192.168.10.5 | | | |
| | | 192.168.10.6 | | |
| | | bridge + samba | | |
+---------------+ +----------------------+ +---------------+
'nexgen' 'vlb-486' 'compaq'
(All machines runs Redhat 5.1 - 5.2 kernel 2.0.36 (not redhat kernel))
When the 'vlb-486' machine is booted, the cards are initialised,
bridging started. And the last card initialised on that machine is
the one I can ping, telnet, osv.. to and from on that machine.
If that is eth1, 192.168.10.6 on the 'vlb-486', i can ping between
192.168.10.6 (vlb-486 on eth1) and 192.168.10.10 (compaq).
And between 192.168.10.2 (nexgen) and 192.168.10.10 (compaq), the
bridge is working.
But _not_ between 'nexgen' (192.168.10.2) and 'vlb-486'(on eth0)
192.168.10.5
(but i can telnet from 'nexgen' to 'compaq', and from there do another
telnet to vlb-486 (on eth1), so i can sit on 'nexgen' and work on the
'vlb-486'. But not directly.)
There is 'no route to host' on the 'vlb-486'. But that does not stop
samba on vlb-486 from popping up (the 'nexgen' is mostly a
win95-machine) as a vlb-486-samba-resource on 'nexgen'. When i try to
open whatever, no go.
So, samba does a broadcast and announce itself. Fine.
But there is still 'no route to host' as long as this (se above) is a
fact:
But _not_ between 'nexgen' (192.168.10.2) and 'vlb-486'(on eth0)
192.168.10.5
If i do a '/sbin/ifup eth0' on the 'vlb-486' it starts to work. (but
then the 192.168.10.6 - 192.168.10.10 is lost..)
The solution is very simple. (If the above is the problem, that is.
And to me it so, a routing problem.)
on the 'vlb-486'
('man route' an then):
route add 192.168.10.2 eth0
route add 192.168.10.10 eth1
So, it _could_ be simpel routing wich is not working of some reason.
>If I do "ping 192.168.1.2 ( i.e. Win95)" from Linux, even the leds of both
>PCs will flash, but there will be no response on the screen! (?)
run '/usr/sbin/tcpdump icmp'(the 'icmp' to get only ping-traffic) on
one console and do the ping from another console.
It should produce something like this (the 'vlb-486' is my
linux-machine):
[root@vlb-486 nexgen]# /usr/sbin/tcpdump icmp
tcpdump: listening on eth0
21:45:10.498573 vlb-486 > nexgen: icmp: echo request
21:45:10.498573 nexgen > vlb-486: icmp: echo reply
Then stop the ping, still running the tcpdump. And try to ping from
the win95 machine:
C:\ping -t ip-nr
It should produce something like this:
[root@vlb-486 nexgen]# /usr/sbin/tcpdump icmp
tcpdump: listening on eth0
21:50:38.398573 nexgen > vlb-486: icmp: echo request
21:50:38.398573 vlb-486 > nexgen: icmp: echo reply
tcpdump puts the card in promiscious mode, it sees everything. (Here
filtered to only see icmp) If there is only 'echo request' but no 'echo
reply'...
Why is it so... (routing? arp? *?)

I would have done it. And set it to something like irq 10 and I/O
0x300, if free. And checked the card while in the 3c5x9cfg.exe. And
set tranceivers to what you use. (saves the trouble with setting it
manually when loading)
Then (or maybe first) i would have entered bios on the machine, set
irq 10 to 'legacy isa' or 'isa only'. And turned off 'boot with
pnp-os'.
Then (or maybe first!) read
http://cesdis.gsfc.nasa.gov/linux/misc/irq-conflict.html
Scsi ? soundcard? motherboard?
>b. You mean Full duplex disabled on both NICs (Win95 + Linux)?
Yes. Full duplex demands a switch capable of it or _crossover_ tp and
full-duplex on both nic's. A hub will not work. I'm told.
If there is a 10/100Mbps nic on the other machine, does the hub handle
speed-negotiation well? (or _crossover_ tp and the other nic.)
http://cesdis.gsfc.nasa.gov/linux/misc/NWay.html
If not, and there is a 10/100Mbps nic, setting it manually to 10Mbps
both in nic-setup and windows-setup on it. Solve that kind of
trouble.
>you mean the '/usr/sbin/tcpdump arp' should show that the
>Linux box was receiveing a request but
If no entry doing 'arp -a 192.168.1.1' on the win machine (or deleting
the entry 'arp -d 192.168.1.1'), yes. Then the linux-box should
receive a request, _and_ reply to it.
(When the win95 machine do a 'tracert 192.168.1.1'.. that is)
>Any more hints?
>It seems that it has to be something very basic, like a switch or

_crossover_ tp cable between the two machines will take away the hub
as a possible problem. When a minimal setup work. It is more easy to
point at what breaks it.

Is there any help in the (/usr/doc/howto/) Ethernet-howto chapter:
4. Performance Tips
4.1 General Concepts
* 4.2 ISA Bus Speed
* 4.3 Setting the TCP Rx Window
4.4 Increasing NFS performance
4.3 Setting the TCP Rx Window
[...]
Recent versions of the route command have the ability to set
the size of this window on the fly. Usually it is only for
the local net that this window must be reduced, as computers
that are behind a couple of routers or gateways are `buffered'
enough to not pose a problem. An example usage would be:
______________________________________________________________
route add <whatever> ... window <win_size>
______________________________________________________________
where win_size is the size of the window you wish to use (in
bytes). An 8 bit 3c503 card on an ISA bus operating at a
speed of 8MHz or less would work well with a window size of
about 4kB. Too large a window will cause overruns and dropped
packets, and a drastic reduction in ethernet throughput. You
can check the operating status by doing a cat /proc/net/dev
which will display any dropped or overrun conditions that
occurred.

Subject: FTP deamon and NAT
Date: Tue, 27 Jul 1999 22:40:53 GMT
Hi all,
After trying to discover the problem myself for too long, I finally
decide to post something in the news...
Here is my problem:
- I have my network hidden behind a masquerade. That's a dial-up router
from 3COM, Office Connect.
- I have access to two different linux machines: one with redhat 5.2,
and another one with mandrake 6.0.
- I'm able to upload whatever I want to the mandrake machine, with
active or passive FTP. My router takes care of the conversion for the
FTP protocol, when passing through NAT.
- BUT, but, but, I have something weired with the redhat machine: after
a reboot (of the redhat machine itself), I'm unable to upload anything
to this machine from my computer (hidden behind a masquerade), but I
can upload from the mandrake machine, without a problem. When an upload
fails, it lets some processes under the user account, visible with "ps
x". And an empty file, with the name of the file I tried to upload.
But read this:
All problems disappear as soon as I log as root on the redhat machine,
go into linuxconf, activate the changes, and exit. Then I can upload,
with passive *or* active connections. It sounds crazy, I know, but I
have just tried again, and the same thing happened.
Here is what I have tried:
- I first thought it was an ftp server problem. I upgraded from wu-ftpd
v.2.4.2 to v.2.5, but it did not help.
- I have finally decided to install proftpd, and I still had this
problem.
- I have also tried installing proftpd as "standalone", instead
of "inetd", but again, this does not help.
Does anyone have idea what else I could check to find the problem? I
have the impression the problem is due to some kind of permissions, but
I don't know where. "chroot()" maybe?

Subject: IP Masquerading and ip_masq_ftp patches
Date: Sun, 25 Jul 1999 15:28:50 +0100
Hi,
I've just set up IP masquerading on my Linux machine so other Win95
machines can use the internet. However my installation (SuSE Linux
kernal 2.2.5) hasn't installed the ip_masq_* patches. In my
/lib/modules directory I have two kernal versions 2.0.36 and 2.2.5. The
2.0.36 has the reevant modules in the ipv4 dir but they have been
compiled for the older kernal and wont work even when forced to load.
The ipv4 dir exists in 2.2.5 dir but is missing the relevant files i
need (ie CuSeeme, ftp, raudio, vdolive, quake, irc etc).
I found the source for a icq module and compiled it and placed it in the
ipv4 dir and insmod'ed it and it worked file. But I can't find the
source for the other patches I want.
Is this part of the kernal source. If it is then it's odd that it was
not origianlly installed as I selected a Network package installation
and other ip masq stuff was installed.
Any help would be greatful
Thanks
Colin Guthrie

Subject: ISC dhcpd and NT clients: force renew?
Date: Tue, 27 Jul 1999 19:42:17 GMT

All,
As we are short on IP addresses, we'd like to add a firewall and do
NAT by using the 10.x.y.z private address plan.
Besides adding "ipconfig /release ipconfig /renew" to each client's
autoexec on NT clients, is there a way on the Linux server to force
clients to renew their lease, so that they'll be updated, and use the
private addresses instead?
TIA,
FF.

Hi,
I have exactly the same problem..
I see that the client try to connect to the local address of the ftp
server (192.168...), this can't work.. (private network)
then, I think that the [better] solution is to find a config in the ftp
server that to this... but I haven't find it yet : for ncftpd, proftpd...
nothing....
I think that I will "hard code" the routable ip (which will have an ip
port forward on port 20 to the server) in the ftp server ...
better idea ?????
