Hello,

I may have posted this query before on other forum but havent recd any reply..... so i am rephrasing it and posing it to all.....


I'm trying to simulate Firewalk (if anyone has used it it would be gr8 help), which uses libpcap, libnet & libdnet.....

For those who dont know, Firewalk is a tool built to enumerate the access control list of the target gateway,

I'm working on simple system which is in a network using RedHat 9.....

When i try to run Firewalk on this system it gives foll o/p:

When i went thru release notes of RedHat 9 it states that it doesn't provide ACL support but provides the packages attr & acl for ACL testing....

Someone suggested I use Fedora Core 3....


I'm very confused as to what to use..... and what is the right thing to do?

Please help as it's very urgent...... Thanks

The ACL support that RH is not providing has nothing to do with ACL:s that are tried to be discovered with firewalking.

The attr&acl RH is speaking is access control lists for the filesystem (eg. to define certaing accessess recursively to some files for some groups).

The ACLs firewalking is about, are access control lists defining network policy.


What are you trying to archieve?

I' m trying to run Firewalk.....

My system uses RH9 its in a LAN..... only one of the machines in this LAN is installed as a server, others are installed as Personal Workstation...


The usage syntax of Firewalk as given is:

./firewalk [target-gateway] [metric]

For target-gateway I gave IP of a workstation in LAN and for metric i gave IP of server.....


Yet i get this output

Firewalk 5.0 [gateway ACL scanner]
fw_init_network(): route_get()

Total packets sent: 0
Total packet errors: 0
Total packets caught 0
Total packets caught of interest 0
Total ports scanned 0
Total ports open: 0
Total ports unknown: 0

I cant understand why this output and what I should do to get correct output...

If you hv used Firewalk previously, u could help me....Thanks
