Just a comment on this (that isn't really Beowulf related - although
security issues of this magnitude affect every Linux system):
In view of the recently published (Mar 27) local root exploit in all
Linux kernel versions 2.2.x with x < 19 it seems to be somewhat
unimportant to me to discuss how you upgrade to 2.2.17. Everybody
should upgrade to 2.2.19 or 2.4.3.
BTW: the exploit is trivial: just download, compile and run.
Tested on 2.2.16 and 2.2.17. Works like a charm :-(
