Title: pppd with static IP address
Post by: Simeon on May 23, 2001, 08:21:33 PM

Hello, I hope someone can help.

We have just bought a Hayes external ISDN TA to use with a new e-smith server to replace the NT server we currently use.

Tried it for the first time today.  The Accura is set to just use a single B channel and e-smith treats it just like a modem.

From reading /var/log/messages, the e-smith box  dials up our ISP (NTL) passes on our username and password which are accepted.  PPPd then starts.  An error is then reported along the lines of 'cannont determine local ip address' or something similar. (I did bring  the log file home on disk in order to post but can't read the disk!) and pppd dies.

I'm guessing that this is because pppd expects our ISP to inform it of its dynamically allocated IP address?  We have a static IP address.   I've tried understanding the pppd man file and it says that running pppd [local] : [remote] tells pppd of the IP address.  Does this then mean that it doesn't ask the ISP for it.

If this is the solution could someone please advise on how I change e-smith config files to run the ppp daemon with it knowing the IP address (static) so it doesn't expect our ISP to dynamically allocate it one.

Or am I on completely the wrong track?

I'd be really grateful for any advice.
Many thanks,
Simeon.

Correct.

More or less. It actually means that it doesn't expect the ISP to provide it.
