Topic: SME newbie - MTU setting for NIC

[marcofranzoso]

Hi all
I am desparate for some advise on how to change my external network card settings...
I have an internal network card and an external network card. The external card is pluged into a RF modem(iburst). When I do a internet test on the SME it always comes back as failed...although I can see the box communicating with the modem. I have set the external card to run with PPPoE which is the connection method and I have supplied the relavant info....alas it still does not want to connect.

I have set this modem up on a stand alone PC and specified the MTU with DrTCP, this is all XP based, and it works fine. .....How does one change these setting for the SME server.

Please help!

Hi marcofranzoso,
   Just to start at the beginning (so forgive me if you've already tried this), have you made sure your modem is in bridge mode?  It may not be a problem with the NIC settings...

this is all XP based

How did you set the modem up, did you use the modem interface itself(via web browser normally), or did you set it up with an install cd or something?

I'm just a newbie myself, so apologies in advance if I'm being too simple with this.

thanks for the reply, JoshuaR
Please excuse the ignorance but how does one check the mode of the modem....Please remember that this is a Wireless Radio frequency internet connection modem.....I don't think that I can access it, please correct me if I'm wrong.

When I was setting it up on the XP system I used an install cd. The modem and service is meant to be compatible with Linux, but HOW to set it up is the question.

Even though your modem is a wireless one, you still plug it into the server. I'm assuming that you plugged the modem in via ethernet.  

Normally you need to find the model name & number of your modem.  To do that, I would suggest searching Google for something like

how insert modem name bridge mode

the results should come up with the instructions of how to do this, but if you post the model of your modem I'll see what I can find out.

To access the modem to make the changes you found, plug your modem into a computer (your xp machine will do).  Then open a web browser like firefox or IE, and then in the address bar type the address of the modem. This address will be the default one that the modem came with, if you don't know what this address is, then Google should help you find this (and the default password which you will need) too.

Follow those instructions you (hopefully) found to put it in bridge mode.  

Also, if your network is using wireless routers or anything you might need to configure those as well--just to let you know in case you have more trouble.

I hope that helps but if it doesn't work or if you need better instructions let me know.

thank you...JoshuaR

I have managed to get the modem to connect....(there was a conflict with updated passwords...silly me )

I still need to change the MTU settings though....!!!!

thanx for all the good advise, i will check thu all of them.

If you're using PPPoE to connect it looks as though you need to:

Code: [Select]

mkdir -p /etc/e-smith/templates-custom/var/service/wan/pppoe.pppd.conf
echo mtu #### > /etc/e-smith/templates-custom/var/service/wan/pppoe.pppd.conf/mtu
expand-template /var/service/wan/pppoe.pppd.conf
service network restart
(replace "####" with the mtu you want to set.  Also there are only 4 lines above - beware of wrapping...)

Or maybe you need to customize /etc/e-smith/templates/var/service/wan/run.pppoe.conf/device...
