How do I start the accounting programs?

[HCART%vax.oxford.ac.uk at nsfnet-relay.ac.uk]

    Can anyone let me know how to start the accounting programs?
I have RTM, but they seem to be clearer on how one runs the
utilities to analyse accounting files than on how the accounting
package is actually started.

    I have made all the directories I think are needed, but when
I run /usr/lib/acct/startup, I get
  
  accton: cannot setuid, check mode and owner

    Can anyone give me a pointer to which  file(s) accton is
probably objecting to at this stage?

    Thanks.
