If what u need is to assign an IP address to a network card, do not recompile
the kernel.
Just use the 'ifconfig' command to assign IP addr, Bcast and Mask to you
network device.
For more help try command 'man ifconfig'.
I hope it helps.

Where do you want to do this?
In userland, you don't have to do it, since the MAC layer is
inaccessable to the user. You use IP addresses.
In kernel, you use the arp module to resolve IP addresses.

Hello,
is it possible to restrict the access to a smtp-server (sendmail)?
I would like to restrict the acces by IP-addresses or host-names.

Date: Wed, 13 Jan 1999 20:39:31 -0600
>From reading the Linux PCMCIA Information Page and other HOWTOs
it does not seem that any CDPD Wireless modems are supported yet.
It is my understanding that CDPD cards are a completely different
from Wireless LAN cards ( which are used for building your
own wireless LAN ).
But maybe some of these CDPD cards use a standard serial interface
and could be used. I noticed this in the pcmcia list

Some how I doubt this is the case. So, I probably should just get
a digital cellular modem for wireless internet access.
Does anybody have any suggestions for a good digital cellular modem?
Or does anybody know anything about the possiblility of using a
CDPD card ?
Or for that matter any suggestions for wireless internet access for
a linux laptop ( must be type II card ) ?
Thanks

If you check out the faq on the Orl www site, it is a known problem. Your
installation fails to setup
the default font path. I got the same, but commenting out two lines from the
configuration file, you should be ok. I am sorry, but I have not the
filename handy.
Anyway, I strongly suggest you to have a look at the faq.

Check the log files in /var/log/messages. Also, you can put an entry in
/etc/syslog.conf that looks like:
# save ppp error messages:
daemon.* /var/log/ppp-log
This will log all ppp activity. Then, you can add the "debug" option to pppd
which will add more information to the /var/log/ppp-log file. It should show
you everything that's going on, right up to the point of connection. If you
successfully are getting connected, but can't ping anyone, not even your ISP,
then there's something else wrong. BTW - if you've got X11 up and running,
I've found the easiest way to get networking (including ppp, etc) configured
is to use the "Network Configurator" (netcfg) applet from the control-panel.
If control panel isn't starting with X, then from a terminal window type:
# control-panel
If that doesn't start, then you should be able to start netcfg the same way:
# netcfg

Robert,
Yes, one way that you can accomplish this is to add the following line
to your sendmail.cf file:
Cwdomain.org
That will tell sendmail that your local host is also called domain.org
and e-mail sent to the host at either address is local mail and should
be delivered locally.

Subject: Re: Pentium with CD -> 486 without
Date: Thu, 14 Jan 1999 12:58:26 GMT
Reply-To: [EMAIL PROTECTED]
Well I am nearly there! I have actually started the installation
twice now - once I ran out of hardrive space (oops) and the other time
there was a receive timout error on plip. The problem is netmask I
think.
Following the execution of my script file...
# ifconfig plip1 192.168.1.1 pointopoint 192.168.1.2 up
# route add 192.168.1.1 add { or sometimes
route add 192.168.1.2 add, and sometimes
both!}
# mount /mnt/cdrom
netmask is listed by ifconfig -a as 255.255.255.0 but by route -n as
255.255.255.255. The RH installation procedure AUTOMATICALLY assigns
it as 255.255.255.0 and then further fills out the Gateway and primary
nameserver fields. As route lists the netmask as 255.255.255.255 and
the gateway as 0.0.0.0, I have been changing them to suite. I have
been alternating clearing the primary nameserver and typing in
192.168.1.1 (IP of the pentium). RH is really keen to fill in all
four fields though!
Another possible stumbling block is the next screen when asked for the
domainname and hostname. I have been listing either...
_ _ _ _ _ _ _ _ _ _ {i.e. blank field}
localhost
or
localdomain
localhost
or
localdomain
localhost.localdomain
Of course it may not matter but then again who knows? When I type
domainname on the pentium I get a blank line but hosthame gives me
localhost.localdomain.
I cannot seem to willingly create the miracle that started the
previous two semi-successful installations. While sniffing around I
pressed Alt-F3 on the 486 and found messages associated with the
installation.
Everytime I tried the install procedure this console would print the
following:
ip: 192.168.1.2 nm: 255.255.255.255 gw: 0.0.0.0 bc: 192.168.1.2
I'm not sure what bc is but the others are fairly self-explanatory.
Any ideas from anyone gratefully implemented :)
Cheers <yawn> - I'm off to the land of nod for some inspiration!

I am still having problems however. I run the insmod and I get the message stating
the device is busy.
If anyone has installed this card I would appreciate it if they could post the
necessary files used and the settings they used on the card.

If you're getting two channel connects in Winderz, you *should* get
them in Linux. You do know, don't you, that no matter what you do,
you can't always get two channel connects? This may be coincidence.
If you want the bloody, off-topic story about why you don't always get
two channels, email me.
