    Suddenly I'm seeing a few 33 character encrypted passwords showing up in
    my /etc/shadow files on several Linux machines.  And on at least one of
    them, some of us whose entries have inexplicably changed from 13
    characters to 34 characters can no longer ssh in.   First, has anyone
    heard of any kind of rootkit or other intrusion that has this symptom?
    Second, what's the easiest way to get a known good md5sum of a linux
    distribution binary like /usr/sbin/passwd?  Solaris has a nice web site
    that will accept an md5sum and spit out the binary that matches it.  Any
    quick and easy way to do the same for various redhat distributions?  
    
     
    
    Thanks,
    
     
    
    Mike
