Heya.. Yesterday someone "attacked" by box by connection to several ports.. In other words, a simple portscan.. yet, since my box has "log_in_vain" enabled, so it tries to log everything to /var/log/messages, since the logfile got full and the size went over 100K, it tried to rotate the log to save diskspace. (Apr 16 21:00:00 omikron newsyslog[32137]: logfile turned over due

Hi, First of all, I know that not dropping SYN/FIN isn't really a big deal, it just makes no sense. But since it doesn't make any sense, I don't see the reason why not to discard them. I'm running pf on FreeBSD 5.4-RELEASE-p3 and I scrub any traffic. I've read some other posts on google and as far as I can tell, clearly invalid packets (like packets with SYN/RST set) is

Hello, For some reason, I thought little about the "clear" command today.. Let's say a privileged user (root) logs on, edit a sensitive file (e.g, a file containing a password, running vipw, etc) .. then runs clear and logout. Then anyone can press the scroll-lock command, scroll back up and read the sensitive information.. Isn't "clear" ment to clear the

Hello.. I've asked this question before without getting any further help really.. When a new user is added using "adduser" on 5.x (havn't really checked if it's the same under 4.x or not), the default homedir permission is 755 (drwxr-xr-x) which to me, looks a bit insecure? It's of course pretty easy to solve it by a simple chmod, but yet, isn't there anyway to

Heya.. By reading my /usr/local/etc/apache2/httpd.conf, I can find out that my Apache is running as the user "www" and the group "www" .. Yet, when I run sockstat, it tells me one of the forks are runned as root and listening on port 80 as well as the other forks are runned by www:www.. If I got a lot of users connecting to my server on port 80, will thier requests ever be

Heya folks First of all, sorry if this isn't the correct list, but yet, I think spam is a kind of network attack and should be treated as a security issue.. I run a working mail server using Postfix, MySQL, Courier-IMAP, SpamAssassin and ClamAV (amavisd-new) .. I've checked the configuration file for SpamAssassin, but yet I havn't find any good solution for spam.. Sure, spam will

Dear list, About a week ago, right after 5.4-RELEASE was released, I received a mail from Gentoo Linux's security announcement list about a flaw in tcpdump and gzip. Since none of them are operating system related, I assumed a -p1 and -p2 of the 5.4-RELEASE. Instead, we got a patch for the HTT security issue so I wonder, is the FreeBSD version of tcpdump and/or gzip are secured or simply

Hello.. I've noticed a delay between when the security advisories are sent and when the cvsup servers, ftp mirrors and web mirrors are updated. Is this delay on purpose to give the users some time to update/patch their system(s) before it hit pages like bugtraq, etc.. or is it just a caused by the delay between when the ftp/cvsup servers are synced? Best regard, Jesper Wallin

Dear list, A few days ago one of my machines were attacked by a DDoS-attack using UDP on random ports.. When I later on analyzed the logs, I found this in my dmesg: xl0: initialization of the rx ring failed (55) xl0: initialization of the rx ring failed (55) xl0: initialization of the rx ring failed (55) I tried to find out on google what it ment, but without any luck. What does that mean and
