public class jh2n

extends java.lang.Object

JH2N - A java host to name server converter.
A java replacement/enhancement of the perl program of the same name. It does operate in a slightly different manner then the original h2n, as this version was written to support the many virtual domains found at an ISP. The -d option is not meaningfull, as this h2n assumes that every domain found in the host file is to have SOA records built. This version takes many of the same arguments as the original h2n. To make jh2n work properly, first create an instance, passing any command line args as a string array. Next use the readHostFile method to have it read the input file and build all the internal structures Next use the writeFiles method to get it to create the named.boot file, as well as all the db resource record files.

Method Summary

static void	main(java.lang.String[] args) Main method is used to allow this class to run stand-alone
java.lang.String	printAliases() prints all the entries in the hostHash
void	printFooter(java.io.PrintWriter printout, java.lang.String domain) prints the $INCLUDE directive at the bottom of the db files
void	printGNUGPL()
void	printHeader(java.io.PrintWriter printout, java.lang.String domain) Used to write the SOA and NS records to the db files Note that the serial number is generated using the current date/time in the form YYYYmmDDnn where nn is a unique number incremented every 15 minutes
java.lang.String	printHosts() prints all the entries in the hostHash
boolean	testForDomain(java.lang.String junk) tests to see if a given domain is supposed to be processed returns false if its in the list of ignored domains
boolean	testForNetwork(java.lang.String junk) tests to see if a given network is in the list of accepted networks
boolean	testNetworkAddress(java.lang.String address)
void	writeBoot(java.lang.String outfile, java.lang.String primaryServer, boolean savefile) writeBoot creates the named.boot file parameters are the output file boolean indicating primary or secondary String indicating a folder to prepend to the files, if the string is null, then don't save the files if the string is empty, then don't prepend anything if the string contains something, then prepend the filenames with the string (note that the string should only be passwd for secondary files, not primaries)
void	writeDomainList(java.lang.String outfile)
void	writeHostPrefixList(java.lang.String prefix, java.lang.String outfile) write the list of hosts with passed prefix but that are on a controlled network!
