Hi Christiaan, I am having the same problem. I posted a message to the ISP list a couple of days ago and it seems as if a number of people are having the same problem.. It has been suggested that I should compile a custom kernel to get around it. Some of the responses have suggested going back to 3.4 rather than 4.0 So I don't think you have any sort of DOS It would seem there is an issue with 4.0 which affects some of us Let us know if you find anything I will do the same regards Tim ----- Original Message ----- From: "Christiaan Rademan" <christiaan@mics.co.za> To: <freebsd-security@FreeBSD.ORG> Sent: Thursday, 22 June 2000 4:48 Subject: Hi All. Greetings.. We here have a FreeBSD 4.0-Stable server, running latest services. ie for mail. The problem is it has been rebooting from time to time.. No reason has been given to me in detail via the log file. The machine has definitly not been hacked according to some probes. I am left with a question, "Did I brake something, or is there a new DoS attack or something else" All I have done is changed the chflags on some odd directories /bin with -R. Directories: /bin - /sbin - /usr/bin - /usr/sbin - /usr/libexec Then I mostley went around removing +x filemodes from some slightly important suid exec, but theyr still excuteable by owner,group : root,wheel. Other than that, the server has definitly not got hardware problems, that has been replaced fully. I also have the system running kern.securelevel=3... via rc.conf I succesfully had a machine running with uptime for over 60days, with the changes. Although now I have to question why the machine reboots during the week? So far, it looks like the kernel is screwing up, for no known reason. I am about to try running the machine on a generic kernel, maybe make an attempt to see if it still brakes. If anyone has a clue what might be going wrong here, please contact me..
