There's one in the debian distribution, can't remember the name
right now, but http://www.debian.org/Packages/stable/net should be a good
place to look for it. The name is quite self-explanatory :) Else, read the
DHCP-HOWTO.

check that you have all hosts that connect to your linux box in your
/etc/hosts file.
also in sendmail.cf that Cw contains your local domain or
/etc/mail/sendmail.cw also has the local domains listed

Hi Rob,
Do you have NT with Service Pack3 ?
After installing SP3, NT only allows to send encrypted passwords over
the
network. To get connected to you samba-server you either need to setup
NT that it would send PlainTextPasswords, or setup samba so it uses a
extra passwd-database (not the standard unix /etc/passwd). There's good
docu on that in http://samba.anu.edu.au/samba/ .
To enable PlainTextPasswords you need to edit NT-Registry:
start / execute / regedit
in
HKey_Local_Machine\system\CurrentControlSet\services\Rdr\Parameters
add the following Parameter:
Value name: EnablePlainTextPassword
Data Type: DWORD
Data: 1
Quit regedit, reboot
try to connect!
Bye
Zoran

Subject: dhcpcd and lease time problem
Date: Tue, 11 May 1999 11:20:26 +0200
My cable modem company (Brutele, BE) assigns me a new IP adress every
week.
The problem is that when this occurs, dhcpcd crashes and my eth0
interface is not there anymore when using ifconfig.
My messages log has this entry (by memory, I'm not at home):
Apr 27 06:16:05 NeXus6 dhcpcd[178]: REBINDING: Lease time expired.
Fall back to INIT
Apr 27 06:17:11 NeXus6 dhcpcd[178]: no DHCPOFFER messages
I then have to manually run 'ifup eth0' or sometimes even reboot the
machine
as 'ifup eth0' is not always working after my new IP is assigned.
I am running RH 5.1 and DHCPCD 0.65.
My kernel is a 2.0.36
How to make dhcpcd work with the new address automatically?
Any help would be appreciated.

we ran into this too; when we connected PC's to the network they couldnt
read aything of there own subnet. So where our network is 157.250.x.x and
we had subnets like 157.250.1.x 157.250.2.x 157.250.3.x etc someone who was
on 157.250.4.x wouldnt be able to see something on the 157.250.3.x subnet.
This wasnt a problem so much for intranet servers, but instead for other
programs running voer IP, for us. But the same difference. So a command
like:
'route add 157.250.0.0 mask 255.255.0.0 157.250.4.101'
(where 157.250.4.101 would be the gateway for the 4 subnet to the
rest of te network) on the win9x machines implimented as the other gentleman
suggested with an NT logon script saves the day. They are able to see our
entire internal network and the internet as well......

Hi Matt
I had a problem with NT using a DEC21041 PCI NIC and it turned
out to be that I had told NT to use the BNC port (which was the one I was
using) rather than autodetecting toe port..... After much hair tearing
I resorted to autodetect and voila it worked.
I knew it was not a hardware problem as exactly the same setup when booted
into Linux worked ok.
Just a thought....

Subject: problems with old SMC/WD 8-bit ethernet card
Date: Tue, 11 May 1999 19:24:10 GMT
Greetings:
I have an old 8-bit SMC/WD 10T ethernet card that I'm trying to get
configured in my system to no avail. I've read the ethernet howto and
various postings which indicate that I should be using the wd8003 driver
(the chip on my card is the 83c690). I've recompiled the kernel to
include the SMC/WD network device drivers, but the card is still not
recognized at boot. I've also tried passing parameters to the kernel
based on how my card is configured (I know the configuration for
positive as I ran SMC's utility, ezsetup, from a dos boot disk which saw
the card just fine.) The string I'm passing LILO is
"linux ether=7,0x2A0,0xC000,0xC8000,eth0" (card configured on IRQ 7, RAM
0C8000, I/O 2A0) I suppose it's possible I don't have the kernel
parameter syntax quite right, in which case I'll need some help with
that.
Anyway, does anyone out there have ideas on how I can fix my problem?
Thanks,
Andy

Subject: Dialup to NT server with callback account, using ISDN
Date: Tue, 11 May 1999 16:43:22 +0200
Hi,
I have access to an NT RAS server with a callback account. The callback
number is fixed (administrator specified). The NT server uses MS-CHAP for
authentication.
I use a Teles 16.3 ISDN adapter, which works fine in Linux with Hisax (I
tested it using a 'normal' dialin account). However, the dialback in
combination with MS-CHAP is a little problematic.
Anyone have an idea?

I've already seen that some-one gave the LINUX-HA project idea to you.
There is a piece of software called VINCA that does the same for NT and Novell.
I must say it is a pretty good failover software. Just like the LINUX-HA.
But the best fail-over software is still NOVELL Netwares 4.11 SFTIII no
downtime at all when a server goes down scheduled/or non-scheduled. If your
missiom critical server is fileserving than this is the best solution for you.
But seeing you run NT it is probably some applicationserver.

Subject: Re: What's the difference between 3C905 and 3C905B, please?
Date: 11 May 1999 15:46:03 GMT
Daring to challenge the will of the almighty Leviam00se, Gary Gourley
([EMAIL PROTECTED]) had the courage to say:
: Hi,
: What is the difference between 3C905 TX and 3C905B TX?
: Hardware bug fixes or performance boost?
The 3c905 uses the boomerang chipset. The 3c905B uses the cyclone
or hurricane chipset. There are a couple of differences:
- The 3c905 requires an external 10/100 transceiver. If you look at
the board, you will see a National Semiconductor DP83840A chip
next to the 3Com one. This is the transceiver. The NatSemi chip
also does the speed and duplex mode autonegotiation. The 3c905B has
all the functionality of this transceiver integrated into the
controller chip.
- The 3c905 retains the old 'vortex' PIO programming interface for
backwards compatibility purposes, which means drivers written for
the 3c59x series PCI cards can be made to work with the 3c905.
You need to use the bus master DMA interface for best performance
at 100Mbps though. The 3c905B drops this compatibility interface.
Note: the presence of the old PIO compatibility interface means
that it is possible (though not recommended) to use the 3c905 in
a non-bus master PCI slot. Most PCs today support bus mastering on
all their PCI slots, but quite a few older ones didn't. This has
led to some confusion in my experience, as people who were using
a 3c905 card in a slave only PCI slot failed to understand why their
card suddenly wouldn't work anymore when they updated to a newer
driver. All 3c90xB series cards must be used in bus master capable
slots, even the 10Mbps only ones.
- The programming interface for the 3c905B has some additional
features which the 3c905 lacks: the 3c905B offers a few more options
that can be tuned and the RX and TX DMA descriptors have some
additional bits that can be used. Most of the features are designed
to tweak performance.
- The 3c905B supports TCP/IP checksumming in hardware, though I'm
not sure how many people use that feature.
- The 3c905B supports Wake On LAN. Note however that 3Com has some
low cost versions of the 3c905B available now for those who need
a 'connectivity solution' without some of the bells and whistles,
such as wake on LAN (e.g the 3cSOHO100-TX OfficeConnect adapter).
- The 3c905B supports power management.
- The media options register on the 3c905 is programmed by pulling up
or grounding pins on the chip when it is soldered to a board. With
the 3c905B, the media options register can be programmed using a
value in the EEPROM. There are a few other differences in the EEPROM
layout too.
There are probably a few others that I've forgotten, but I think you
get the idea.
: A shop tries to sell a 3C905 card to me in a bargain price
: ...
I would take it. 3Com doesn't make the 3c905 anymore. I only have
one of them which I use for testing and I don't plan to give it up.
: B or not(to) B, please? I have checked the 3Com webpage but
: no information on the difference.
Both the 3c905 and the 3c905B should perform very well, although the
3c905B is optimized to try and reduce the load on the CPU. I can easilly
saturate a 100Mbps link at full duplex with a 3c905. I've heard people
complain a lot about the 3c905B, but I've never had trouble with them
(caveat: I use FreeBSD, not Linux, but that shouldn't matter). I think
part of the trouble is that many people used (and still use) Red Hat
version 5.x which did not have very good support for the 3c90xB series
cards when it was released (not that they wanted it that way; the card
was just very new at the time). Consequently, a lot of people got off
on the wrong foot with them.

You can relay on IP portnumbers with the rinetd package.
That way you can tell that a call to Internet IP address on port 80 beeing
relayed to some other server on your local net (behind the firewall).
Check it out that way you can reduce the amount of IP addresses.
