Hi Doug As I explained earlier, I performed the ffg sequence of events. - I installed 2.2.7 WITHOUT the source code. - I then installed the sys source code distribution. - I then needed to change the kernel configuration for PPP, so I copied the KERNEL configuration file to CUSTOM. - I made the necessary changes and made the CUSTOM kernel. - I rebooted the machine and found that I couldn't telnet to it. So I worked at the workstation console itself. I found that for example if I typed 'ping localhost' or 'netstat xxxx' functions I iether got timeouts or long waits. ( I assumed then that the old kernel contained configuration details were not on the /sys/i386/CONFIG file [which I only installed after the original kernel was built :( ] ). - I rebooted of /kernel.old and those problems seemd to go away. - I searched for the ORIGINAL kernel file. The only one was the /sys/i386/KERNEL - but I suspect that was what caused the problems in the first place. - There was a /kernel.config file but this was empty. Now I need to make the PPP changes that I set out, but I need a config file that reflected my configuration at installation time. The changes that I made to the KERNEL file is:- pseudo-device tun 3 # ^^^ changed from 1 to 3 Hope this helps.

Please explain what you mean by 'lost my old configuration.' If you were expecting the -c changes to migrate, they won't. If you want them to be present when you build new kernels change the kernel config file.
