We have released a new version of rpcscan, version 0.3. Last week's release was fast in case something nasty came out soon, this release attempts to be much more thorough. It incorporates all of the changes people sent into us (thanks!!)...
Phil, Attached is a suggested patch to add a new option (-f) for allowing the list of target addresses to be read from a file. This option adds flexibility over scanning an entire Class C or Class B, at the obvious cost of needing to create the file of addresses first. The following utility can be used to easily create a file containing all of the IP addresses in a network, or a collection of networks: <http://people.musc.edu/~gadsden/tools/misc/subnet2ip.pl> For example, let's say you want to scan an entire Class B network, but you do -not- want to scan several dozen "fragile" legacy systems scattered within that network. Just use subnet2ip.pl to create a file containing all the IP addresses in your Class B, and then edit out those specific addresses you do -not- want to scan. Now, with the -f option, you have an easy way to scan the desired targets, and only the desired targets. For example: $ echo "192.168.0.0/16" > mynet $ perl subnet2ip.pl < mynet > myips (generate file with 65535 addresses) $ vi myips (delete the specific addresses you do not want to scan) $ rpcscan -f myips Thanks, Richard --- o --- Richard Gadsden Director of Computer and Network Security Medical University of South Carolina Charleston, SC, USA ********** Participation and subscription information for this EDUCAUSE Discussion Group discussion list can be found at http://www.educause.edu/cg/.
