After detail checking of vortex site and newsgroup, I think I need to
compile the 3c905B source code (3c59x.c) in order to make the
NIC works. But I fail to compile the source code after followed its
guide and the links to compiled module in vortex are broken.
Can anyone kindly send me the compiled 3c59x.o module? Thank you!

Anyone know a tool that runs on Linux that can help me
diagnose a DHCP issue? I want to be able to capture the
DHCP requests. If it decoded them it would be a bonus!
Can tcpdump do this?
Please cc my email as well, thanks,

Hi Neil.. this is a section in many linux networking books.. it's
usually a very small section, since the format for this file is pretty
simple.. IP name alias .
For more you might visit the NET-3-HOWTO or the NET-2-HOWTO.

IIRC, this is the correct behavior for a dhcp client. Besides, it so so
damned easy to change the IP address on my Linux box even the NT95 bigots

Subject: weird network interface
Date: Tue, 2 Feb 1999 11:40:56 -0700
Greetings!
When I checked 'ifconfig' on my machine, I got something that I find
weird:
eth1 Link encap:10Mbps Ethernet HWaddr 00:C0:F0:30:AB:75
inet addr:192.168.1.1 Bcast:192.168.1.255
Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:20851908 errors:119757 dropped:0 overruns:0
TX packets:0 errors:0 dropped:0 overruns:58242677
Interrupt:18 Base address:0xf880
It is weird because I have a lot of TX from this interface, but it is
reporting 0. And I am wondering why I have such a high number for
overruns and errors. Everything runs fine though. The network card
is one that uses the DEC21140 chipset, and I am using the tulip driver
with 2.2.0 kernel. I have another Intel EtherExpress Pro 100 that is
showing the same thing.
Any help will be greatly appreciated.
Thank you.

C. J. Tan

Josh, of course you checked the file /etc/inetd.conf to make sure that
the pop3 line was there and not commented out.. right?

Hum.. maybe access is being denied when another machine accessed the
samba directory. Of course, you check your /etc/smb.conf file to see if
sharing is on/off (see man smb.conf for a description of this file and
in particular the "share modes") And, of course, you checked your
/etc/smbpasswd file, if you have password access to your files..

Hi,
Does anyone out there use Linux with the New England ISP JavaNet? Their
helpdesk appears to be fairly clueless on Linux issues. I'm trying to find a
chat script that will trigger PPP at their end. So far I can login ok, but
it would appear that their ppp is not starting and my pppd is trying to talk
to a shell account...
If anyone has a chat script that works with JavaNet I'd be forever in your
debt.
Thanks in advance,
Andrew

Brian ,
According to the Masq Apps www page...netmeeting will work...see the
quote from the site below:
================================================================================
Microsoft NetMeeting
Submitted by: Jm Valera
Please don't send Jm a message if you can't get it to work. Many have
gotten it to work and are happy about it, and those that can't get it
to work need to try harder. If you don't believe that those are the
ports used by Netmeeting, go to the Microsoft Web page and look for
the RK on Netmeeting 2.0 (and 2.1). The settings were written for
Kernel 2.0.30. I have also gotten it to work with 2.0.31. I am using
Kernel 2.0.31 and will not support anything newer until I upgrade
myself. Don't ask me for help getting it working with 2.0.33, I won't
try unless I have to myself. Again, it is possible for this to work. I
have done it and so have many others that have thanked me.
Kernel: 2.0.30
Tested with NetMeeting 2.0
Primary TCP connections:
This will allow what microsoft calls the 'Primary TCP Connections' to
work. This will allow such features as: application sharing,
whiteboard, chat, file transfer, and directory lookups.
ipautofw -A -r tcp 389 389
ipautofw -A -r tcp 522 522
ipautofw -A -r tcp 1503 1503
ipautofw -A -r tcp 1720 1720
ipautofw -A -r tcp 1731 1731
You can make only outgoing calls. I have not tried incomming calls but
it may work if you have previously connected to the same user.
Secondary TCP/UDP connections:
This will allow what microsoft calls the 'Secondary TCP and UDP
Connections' to work. This will allow such features as: audio and
video conferencing using the H.323 protocol.
ipautofw -A -r tcp 1024 65535
ipautofw -A -r udp 1024 65535
This is a big security risk because of the large number of ports that
have to be opened. I have tested the voice portion to work with FD
audio. My video camera is on the fritz and was unable to test that
portion of the program. This is provided for informational uses only
and is not recomended. Primary ports must also be setup for this to
work

Subject: Gateway Configuration
Date: Tue, 2 Feb 1999 16:10:31 -0000
Hi,
I have the following scenario :-
ppp internet connection with assigned range of ip's 192.168.0.40 through to
192.168.0.47. The ppp 'device' is sitting on 192.168.0.41 and the machines
ethernet card is on 192.168.0.42, with the default gateway set out onto the
net. The netmask is set to 255.255.255.248 for both devices.
** I know these IP ad's are incorrect (and unsuitable!)
- I'm just using these as an example!! **
I have other machines on the ethernet side with assigned ip's in my
allocated range. I have no problems accessing the internet from the main
gateway box or connecting to the local machines. However, I cannot access
the net from any of the local machines - unless I run ip masquarading (which
I wish to stop using in order to have several machines handling different
incoming services).
I know I'm missing something pretty obvious here - but I need a prod in the
right direction!,
Thanks!,
Steve.

No I don't think so, you seem to be wanting to run netbeui, which is
win only. But wat can be the problem with netbios over TCP/IP (ie
Samba (www.samba.org) ? This is just as secure as unix itself (well
almost, but 4 sure much more secure than netbieu, as you can use the
normal Unix file system including it's security withsamba

We have a machine set up to receive syslogd messages from some other machines
so we can centralize our logs. It gets about 2-3 log entries per second.
It's a pentium 200mhz with plenty of ram and stuff, scsi disks, etc....
The syslogd process stays at about 70% cpu load! When we do some analysis
on it we see what appears to be a lot or DNS lookups on the
sending hosts. We put them in the /etc/hosts file thinking it would help
but the load is still high. Doesn't make sense. Anybody seen this or fixed
this?

I know that dhcpcd can be configured to call a script when it
successfully receives an ip address (via "-c <script filename>").
When it renews its lease, will it call the script again?
I am presuming that everytime it receives an acceptable DHCPPACK packet,
dhcpcd will consider that it has received a new ip address and will call
the script. I just wish to be certain that the client is actually written
this way.
