-----BEGIN PGP SIGNED MESSAGE----- Hello freebsd-questions, I've there had a very strange server crash last night. The machine did respond to pings (sometimes at least) as well as to port scans but nmap showed ports 22 and 80 as being filtered which is close to impossible as ipfw is configured with default pass (and securelevel 2 so a cracker normally shouldn't be able to change this), connecting to any port didn't work, though. When I then went onsite to the colo and wanted to login using console, the system was printing some error messages from time to time to the console but login was impossible since there simply didn't appear ANY character on screen which brought me to the idea that probably something was chewing up all CPU resources... Is there any current DoS attack with such a signature? Best regards, Gabriel -----BEGIN PGP SIGNATURE----- Version: PGP 6.0.2i iQEVAwUBOvFdAMZa2WpymlDxAQFrTgf9FU4K04Gv6ICaFkxZcU3r/hEmNXLxiUV3 Udrnl4Ke9NZB+R0UurmLPNsoqJAnVnRbJsUr+29wlZr/moyNPAAJ/LhDhIdBwU9Q a4Jt1Ztnpp99QOvpCos2koz+jkSCSudSQtukm4WnaVealbhTOuNeUWa2pDrh+7F+ Rm8ZReXNjU8W1SMdMDYhyiJRpfSFP2fXa1M5rc4TvvLOy2ZPoD6L3O4tQf8jvc4f AZN8fY9iGR6u8NgtUQkaWzxhSl6yqdqFxIQTPNoUWZ/kywzzUYuPYjE5oVDcEFJv 9xwJN8UrdAqR2RuvHs657di/5pwM21KWY6kwsWRmtSqvnX2Pa2cMeA== =u1p7 -----END PGP SIGNATURE----- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
