Hi!
I've got an old SC&C NE2000-compatible Ethernet network adapter,
unfortunately without documentation.
The card is a non-PNP ISA Card, YCL chips.
The PCB markings read: 'NE2a/Ethernet' and 'ASSY 121027 Rev.1B'
It has 2 JumperBlocks 2x6Pins (numbered 2-7 ... IRQ? )and 3x6 Pins plus
sevreal 'rogue' jumpers...
And there is a DIP-Switch (10 Switches).
Is there a resource on the net where I can get documentation for
Jumper/DIP-Switch Settings
or can anyone give me hints how to configure this thing for io=0x300
irq=10 ?
bye,
cord

A login that defaults to root? Throw the system out! It's a serious

Before networking my machine. The boot-up was pretty fast. But now,
there is this long (30-45 sec) pause on "sendmail" during boot up.
Why???

2 questions come to mind - what makes you feel that the proxy server is more
secure? The fact that packets can not be "faked"? That they actually must
be valid packets at the application level? I guess this helps cut off a lot
of spoofing and packet level attacks, but is it realistically that much more
secure?
How do you handle UDP & ICMP packets with a proxy server? From what I
understand, the new SOCKS server (Nec V. 5) can be configured to handle UDP,
but what about ICMP?
Secondly, which is easier to configure when it comes to Dynamic IP
addresses - either due to dial on demand, or more importantly, when a
company renews your IP address (ie: in the case of cable modem and/or
ADSL)....

Subject: brcfg & ipchains prob
Date: Fri, 09 Apr 1999 16:20:12 GMT
Hi
I used brcfg with ipfwadm on 2.0.36 previously and the whole thing went very
very well. I could control the forwarded routes and so on using ipfwadm.
However, on one of my installations on Redhat Version 5.2 with Kernel 2.2.5, I
found that the bridge seems to have taken precedence over brcfg even after
recompilation of brcfg.
The prob is simply this.... I enable brcfg with (both ethernet cards on the
system in promisc mode):-
brcfg -ena
Then i put in deny policies for input, output and forwarding on ipchains. I
am not able to ping out anywhere using this setup on the router/firewall
machine. However, the two segments are talking to one another where they
should not, since ipchains has DENY policies for input, output and forwarding
and no other rules.
Any ideas, anyone?
Rgds,
Woolfie

That error generally implies a routing problem.
Are the IP addresses on the same subnet?
Do you have the appropriate subnet masks on both machines?
Do you have a default route configured on the Linux box?

Why not just setup an IMAP service on a Linux server? I doubt you'll

If you are using the version that came with RH 5.2 is is the 1.9..xxx version.
Go get the latest version, it has a lot of new features and supports Win98, NT
better. It also has good documentation.

Check the permissions on /usr1/bok. Even if the directory exists if bok
doesn't have permssions to it, you'll get that message.

What 'route' says? There should be no 'default' route before
pppd is started, and a 'default' route via ppp0 after.
Try also 'traceroute' via ppp0.

At startup sendmail tries to map IP addresses of all IP interfaces
to DNS names if DNS server does not know about them it
takes some time to get "I do not know response"
1) I think that in 8.9.* there is an option to disable it
(*interface* ?)
2) you may add all local interfaces to your /etc/hosts

This all started when I tried to set up WinRSH from a W95 box into my
Linux box.
I got all sorts of suggestions. I checked hosts.allow, and inetd.conf,
and everything looked fine.
So, someone at work suggested trying to rsh from the linux box back to
myself just to see if I could get a connection.
I can ftp, telnet, rlogin, but I get a "Connection rejected" message
when I try to rsh.
What am I doing wrong???
All I want to do is start a shell on my Linux box that is originated by
a W95 icon.
Thanks in advance for the help!!!

Date: Fri, 09 Apr 1999 17:01:50 GMT
Hello everyone, I have a few questions on setting a HP4000 printer modes.
First of all how do I switch duplex modes on a HP4000 that is on a network.
Recently I have magically set my print job to duplex mode and I don't know
how I did that. Here is my printcap.
lp|HP4000:\
:sd=/var/spool/lpd:\
:mx#0:\
:lf=/var/spool/lpd/error_log:\
:lp=/dev/null:\
:rm=255.255.255.255:\
:sh
Was there anything else I need to do?
Second I was trying to create in my printcap different print mode to do
either do multiple page or single page modes. Since it is a network printer
I need to something "tricky" to do that. Any suggestions as to do it.
Thanks!

Now he really won't try Linux.... good job.
To answer the original poster's question... don't know of automatic tool,
but using an ip or port scanner will show you all the machines in an ip
address range. It's considered VERY inappropriate to scan machines that
you don't control (makes me wonder what you might be looking for...) but
doing it in the domain you're legally administering isn't.
A tool like nmap will tell you a whole bunch about the machines in your
network.... probably more than you need to know. Or a shell script that
attempts to ping every ip address and reports which ones replied...
But automatically drawing this? Showing hubs and cable drops... no way.
How would such a tool identify unmanaged hubs and passive drops. You can
only determine premise cabling layout by inspection.
So... at best, an automatic tool **might** be able to find all the used
ip addresses, **might** be able to talk to managed hubs and switches to
find out their used ports and which MAC addresses are on each port, and
**might** be able to associate each ip/mac with a port.
This assumes, of course, that the tool knows how to talk your <insert
vendor name here> switch to get all of this information, and that the
switch can dump this info.
Hope this answers your question if it doesn't solve your problem.
