These are per itsme: • Netware 4.1 : type 512 chars on the console + NENTER = abend • Netware 3.11 : NCP request 0x17-subfn 0xeb with a connection number higher than the maximum allowed will crash the server (yes you will need the APIs) If you have console access, try this: • At the server console type UNLOAD RENDIRFIX • Use your local copy of SYS:PUBLIC/RENDIR.EXE • In SYS:LOGIN type RENDIR (login not required, just attaching to the server) Another thing to try, with console access, is LOAD RARPSERV.NLM quickly followed by UNLOAD RARPSERV.NLM which will abend a Netware 4.11 server (tested with Service Pack 4 loaded). If RESTART AFTER ABEND is set (which is the default) the server will reboot. Using UNICON to UNLOAD RARPSERV.NLM and it should unload cleanly. There are several flaws regarding NCP that can allow for interesting Denial of Service that will crash a server. One utility, Havoc, was released with Pandora, and a couple more (Burn and Yang) are available in our projects list.
