Register Product Manager Check Point Software ------------------------ From: Yanek Korff <yanek () cigital com> Subject: kernel panic [linux 2.2.19-7] on UDP scan CP4.1-SP5 Date: Wed, 14 Nov 2001 15:40:24 +0200 To: vuln-dev () securityfocus com I'm testing out CP4.1 SP5 on Linux RH7.0. I seem to have gotten everything configured the way I want it and am starting to run some scans to see what I can see. Well, what I see is: nmap -sU -P0 ip_addr causes the machine to instantly crash with a kernel panic, or in some cases, reboot. I'm not great at troubleshooting kernel/module troubles so any help would be greatly appreciated. IF you happen to have a Linux CP FW-1 box you could run nmap against, I'd love to know your results (incl OS/kernel info). Might want to do this off-hours, though. Without CP-FW1 running (/etc/rc.d/init.d/firewall1 stop), I cannot cause a kernel panic with a UDP scan. Has anyone else noticed this behavior?
