When I try to open Help Index it teels, that it is impossible to connect with localhost:4444

in /etc/services I have found:
krb524 4444/tcp # Kerberos 5 to 4 ticket xlator
krb524 4444/udp # Kerberos 5 to 4 ticket xlator
Do I have to install any special servers to see maya's help?

In /usr/aw there is nothing like "krb524"
