hi Peter,
well, if v use Runtime.exec() in a manner that is hazardous then YES. it is not recommended. by hazardous i would mean,
if we use absolute paths which are system dependent (like the one i use in the first commented invocation of the exec() having /usr/sbin/nslookup.
in this case it is no longer system independent as it will only work on Unix/Linux where we have nslookup on /usr/sbin/ (well thats the case most of the time though)...
otherwise i really don see a whole lot of problems w/ it in comparision of efforts we will have to put in implementing
RFC1739 u can probably find impl in java by googling on "nslookup in java" or something....
anybody else has more views on this?
regards
maulin
