I've got details from my mac but don't know how to interpret: Sue:~ suemeggison$ dscl . list /users _amavisd _appowner _appserver _ard _atsserver _avbdeviced _calendar _ces _clamav _coreaudiod _cvmsroot _cvs _cyrus _devdocs _devicemgr _dovecot _dovenull _dpaudio _eppc _ftp _installassistant _installer _jabber _kadmin_admin _kadmin_changepw _krb_anonymous _krb_changepw _krb_kadmin _krb_kerberos _krb_krbtgt _krbtgt _lda _locationd _lp _mailman _mcxalr _mdnsresponder _mysql _netbios _netstatistics _networkd _pcastagent _pcastlibrary _pcastserver _postfix _postgres _qtss _sandbox _screensaver _scsd _securityagent _serialnumberd _softwareupdate _spotlight _sshd _svn _taskgated _teamsserver _timezone _tokend _trustevaluationagent _unknown _update_sharing _usbmuxd _uucp _warmd _webauthserver _windowserver _www _xgridagent _xgridcontroller daemon l* nobody root *meggison *meggison is me, and l* is my son, but I don't know the one above him and the two inbetween - could these be hackers?
