    This morning at about 2am, someone managed to get into my machine using
    some type of mountd exploit. I was watching at the time, so they werent
    able to do much damage, but it looks like they were able to nfs mount my
    root drive remotely, even though its not listed in the /etc/exports.  I
    was led to believe it was mountd by this:

    The guy had added a line to my /etc/passwd and inetd.conf files allowing
    for easy root access, but didnt do much other damage.  I'm not very
    familiar with mountd and I havent heard anything about remote exploits, so
    i thought i'd post about it.
    
    
    I couldnt find a current contact for the linux nfs package, so thats why i
    posted here first.
