I've been playing around with LE2005 for a few months now and after the trauma of getting my SAGEM fast 800 USB modem running ADSL on ppp0 I have been trying unsuccessfully to get the LAN working. The hardware is a Realtek RTL 8139 which runs perfectly on my 3 pc LAN under windows!

LE2005 assigns eth0 automatically and claims to be "up" despite the fact that it has no ip address. Allocating one manually does not help.

I used "control centre" to configure the LAN and assigned eth1 as offered. This installed without complaint and sure enough appears in IFCONFIG as eth1 with the manual ip I assigned.

However, pinging to or from the new address indicates packetes are not getting through and to all intents and purposes the system is not connected.

Amazingly, when I go back to "control center" and use the network connection monitor, the graphical display clearly shows the received ping activity from other machines on the network. So is it working or not? I certainly cant get any other signs of it being connected to my LAN.

To add to the confusion - my ADSL intenet connection on ppp0 is described as "eth0" in the "control center" graphical monitor and clearly displays the internet traffic.

Does anyone have ideas on how I can sort out this mess without doing a major re-install?

Regards
IK

(ps - I am currently not even trying to share the internet connection over the LAN. Just to have both working separately would be a major step forward.)

Have you tried just going through the Mandrake internet connection sharing wizard? It might fix things up properly for you.

Thanks for the reply tkedwards - here it is:

The last time I tried the internet sharing wizard it screwed my internet connection completely. I haven't dared try since!!!

Hello all

tkedwards gave me a clue when he mentioned SHOREWALL. If I stop SHOREWALL in the control centre/services then I can both ping and browse my LAN.

When I restart SHOREWALL the LAN dissappears again.

I have looked at the various files as suggested but I'm afraid I have no idea how to set up SHOREWALL to accept the machines on my LAN.

Can anybody help with this please?

IK

Hello again - further to my last post - I have SHOREWALL running again with the LAN now functioning by editing the file /etc/shorewall/zones to include the line :"loc eth1 detect"

Great! the immediate problem seems solved - Thanks again to tkedwards for pointing me in the right direction.

Now to pursue the possibility of having other machines on my LAN browse the internet through this server.

"Idiot's guide" instructions for achieving this would be most appreciated.

IK

Make sure is in /etc/shorewall/shorewall.conf
Try changing the line in /etc/shorewall/masq to

OK many thanks. - Now have it 50% working! .........

3 PCs on the LAN, each can see the other, share files etc.

PC0 running MDK LE2005 - connected to internet thro' ADSL usb modem
PC1 running MDK 9.2 . I can browse the internet over the LAN no problem
PC2 running WinXP. Can't browse the internet but can use internet explorer to browse the Apache server running on PC0 !

It must be some setting on the windows box - I will keep on poking about.

Thanks again.
IK

PS I just checked my shorewall/Masq file and the interface line says :"ppp0 192.168.0.0/255.255.255.0 ???????

OK - got the windows machine cracked - I needed to tell it about the gateway (PC0) and the DNS at the ISP. Works fine now.

Well I guess I should really start another thread, but I'll try here first:

With all three machines capable of internet connection now I can pick my mail up at any of them. But what I would really like is to have all the inboxes synchronised and containing the same mail.

Unfortunately with the current set-up, downloading mail into one box means it is then not accessible by the others.

Do I need to run some sort of a mail server to achieve this?

IK

Yes. Basically you need to do 4 things:
1) Setup postfix for local delivery. This means you should be able to send email to username@localhost and see it appear properly in your /var/spool/mail/username. Use mail from the command line (if you don't have that command install the package mailx or nail).
2) Install procmail, setup postfix to deliver through procmail and create a .procmailrc file in your home dir.
3) Install the imap package. The one that comes with Mandriva (wu-imap I think) is fairly basic and shouldn't even need any configuration. It should just pickup the mail from ~/Mail
4) Install fetchmail and fetchmail-daemon and configure fetchmailrc to collect your email from your ISP
