hi,

Could someone (as Linux users) kindly inform me how I might go 
about working around a kernel panic when I try to recompile the 
kernel (2.0.0) on my laptop.  I get 'kernel paging errors' at 
different places in the compilation process.  
1. Thinking it was hardware, I tried switching out a 8MB and 
   16MB memory module with no effect.
2. Thought bad kernel image, so I compiled an image using a
    486 desktop, and moved the image over.  No difference.
What should be my approach in tackling this?


An easier question that I have is a sendmail phobia, ahem, problem;
How do you map the (envelope?) From: addresses of outgoing mail
from user1 at mydomain to user2 at my_isp's_domain.  (Having the correct 
address facilitates replies from others.)  You use the DM in 
sendmail.cf to masquerade the domain, but what about username 
translation.  I assume it has something to do with (from sendmail.cf)
    # Generics table (mapping outgoing addresses)
    #Kgenerics dbm /etc/genericstable
1. ...but, I could be wrong about the approach
2. What is the structure of that file? Similar to /etc/aliases?
   Documentation references July 94 issue of Linux Journal as
   an excellent source, but I don't have it.
Before I dig out the source, am I even headed in the right 
direction?

TIA,

      mail as root, but it illustrates my problem with mail headers.)
