Usually cyrptic ASCII strings (the usual mixture of letters, numbers and
special charcters for example something like 'G6d(f&dRmdfb?h+Es7bD2f'
are used. Length should be at least 8 chracters, strings longer than 25
chracters are pretty uncommon and hardly neccessary, using strings of
the 'dog, cat and mouse' type is definitely not a good idea escially if
the remote gateway is set to 0/0
