Subject: regaining my lan after installing cable modem.
Date: Sat, 17 Jul 1999 08:46:36 GMT
Another confused newbie here...
I had a perfectly good working lan with 3 win98 machines and 1 linux.
Now with my cable modem connected to the hub, I don't have access to my
lan any more, but i am quite nicely set up for the internet. I have 3
distinct IP addresses from rogers for the multiple IP configuration. I
basically understand the problem, and here's what I've done so far:
I now have 2 nics in the linux box, and I took the cable modem off the
hub and plugged it into the other nic. I want 1 local address like
192.168.1.x on 1 interface, and DCHP on the other. No matter how i mix
and match the cables and configurations, when I do an "ifup eth0/eth1",
it fails for the DCHP interface. Its like it can't see the modem. I
would like to get out over the net on the linux PC as a first step.
Can anyone help with the software configuration to get this working?
Much appreciated,
rick

Date: Sat, 17 Jul 1999 18:42:18 +1000
I am trying to work out the same problem. I noticed that dhcpd 3 will have
dynamic dns functionality. Unfortunately, this is still in beta form. At the
moment i am playing around with the samba netbios name resolution trying to
fix my problem..
I want to know if dhcpd can some how update the dns when it allocates an IP.
The DHCP lease file seems to know everything about the client machines.
Until then i am forced to allocate fixed ip's
I have read all the applicable howto's and samba docs. Could someone please
explain the 'proper' solution.
My lan has mixed linux and M$ machines with linux server.

You don't need to get a new card. The 3c905C is a fine card. The "test"

I've not used squid, but ip masquerading is set up to do exactly what
you're asking. Check the ipchains man page.

Putting the line
*.* /var/log/messages
in syslogd.conf makes _every_ message go into the specified file.
This only applies to daemons/programs that make use of syslog, of
course (but most all of them do).
It also leads to *huge* amounts of output from - say - pppd! Be
warned :-)

NT uses encrypted passwords, SAMBA per default unencrypted ones.
Change the SAMBA options (see Encryption.txt in the SAMBA sources).

Please use the real addresses or network ranges, otherwise routing
issues are close to impossible to resolve.
Just as a sidenote: If the internal network is using reserved IP
addresses, you'll need IP masquerading. And of course, you'll need
IP forwarding enabled.

Monte,
Yeah, that side of things is fine.
I guess what I am really looking for is something a bit more robust.
What I would like is something that understood both win95 drive mapping and
linux scripting and allow some centralized management such as standardised
scripts that maps drives and printers onto the client win95 PC in such a way
that the mappings will move with a user if they log on at a different PC.
The samba end of thing on the linux server works fine
I am probably showing my roots as a novell installer here, but hey, we all
gather prejudices as we grow :-)
Does this make sense or am I missing something thats already there

Hello all,
I am trying to use 2 analog modems to dial back to work and then bond
them for one pipe of throughput. Here is some info. I am using two
analog modems to dial into a Cisco 2510 with pppmultilink on the two
dial-in interfaces. I have eql built into the kernel and here is the
commands I have used:
ifconfig eql <local ip> mtu 1500
eql_enslave eql ppp0 24000 (slow connection)
eql_enslave eql ppp1 24000
route add default eql
When I get both lines up, then I telnet to a server (AIX) and have to
throw a display back local: xterm -display <one of the dial-up
ip's>:0.0&. Then when I do an ifconfig it shows all the traffic going
through the interface that I had to put in for the display. My question
is how to get the connections to act as one. Is there something else I
need on the router?
Now that this is clear as muddy water, any help would be greatly
appreciated. I am very new at trying to set this up.

Hi,
I had the same problem a time ago.
First you have to run samba (if you don't know how, there are a lot of mails
in this newsgroup that
tell you how).
How I solved the problem is this:
In the file /etc/rc.config you have set next settings:
START_PORTMAP="yes"
NFS_SERVER="yes"
You have to type in the global section of your samba configuration file
(/etc/smb.conf) next lines:
domain master = yes
domain logons = yes
Reboot your pc, and time-out is history.
That solved my problem.
Good luck!
