Someone I knew (Carsten Rossenhoevel) developed a portable alternative
once:

    ( ps -ael ; netstat -s ) |
    compress |
    tr "\100-\377" "\007-\077\001-\077\001-\077\001-\077" | 
    tr "\001-\077" "9a-f0-9a-f0-9a-f0-9a-f0-9" |
    fold -32 |
    awk '{ l1=l2; l2=l3; l3=l4; l4=$0; } END { print l1 }'

Allegedly this runs on a *wide* variety of Unixen; I have used it
myself on SunOS (4 and 5), HP-UX, Linux, and FreeBSD without
modification.

Greetings, Juergen.
