Got raw > from ???.???.???.???:?????, blocked or no more free nodes! Both you and Jeff see this message, I think Jeff mentioned to me he sees it often. I don't see it that often (who knows why, not as many idiots hitting my servers??) We both use iptables to ward off jerks, I'll show you the lines I use for iptables at the end of this message. >I have been running telnetd, rawd, ftpd and smtpd without issues. Once I added > http and https to my bbbsd command line I've been seeing the above. After a > time nothing responds anymore, not telnet, not raw and not ftp. In the past when this did happen to bbbs over here, restarting the bbbsd daemon helped. I generally kill the daemon and restart it about every two weeks just out of habit. To clear the whatevers, if you know what I mean :) > Needless to say that is just not going to work. :) Understand. I checked my inet.log and don't see any connections from ???.???.etc. >I'm not sure what the problem or solution might be.

The first thing I do after a reboot of the _system_ is iptables -F and iptables -X to clean out the automatically installed iptables. Then after that I send the following commands: REM example: iptables -A INPUT -s IP-ADDRESS -j DROP So I kill yandex.com and also semrush.com because they hit my system every day, and often like this: iptables -A OUTPUT -p tcp -m string --string "yandex.com" --algo kmp -j REJECT Then I use a different line to stop idiots from smashing my HTTPD bbbs mailer like this (two steps) One: sudo iptables -I INPUT -p tcp --dport 8090 -i eth0 -m state --state NEW -m recent --set Two: sudo iptables -I INPUT -p tcp --dport 8090 -i eth0 -m state --state NEW -m recent --update --seconds 60 --hitcount 2 -j DROP 8090 is the port I have always used for BBBSD. You would change that to the port you use for bbbsd. Hope this helps :) Take care, Janis --- BBBS/Li6 v4.10 Toy-4 * Origin: Prism bbs (1:261/38) SEEN-BY: 1/123 14/5 15/0 19/36 34/999 90/1 106/201 116/18 110 120/331 SEEN-BY: 123/140 128/2 153/757 7715 203/0 218/700 221/0 1 6 360 222/2 SEEN-BY: 226/30 227/114 229/101 426 452 1014 230/0 150 152 240/1120 SEEN-BY: 240/5832 249/206 317 250/1 261/38 100 266/512 267/155 275/100 SEEN-BY: 280/464 5003 282/1031 1056 291/1 111 292/140 854 8125 317/3 SEEN-BY: 320/119 219 322/757 335/364 340/400 900 342/13 200 396/45 SEEN-BY: 423/81 640/1111 1138 1321 1384 712/848 801/161 189 2320/105 SEEN-BY: 3634/12 5020/1042 PATH: 261/38 640/1321 1384 221/1 292/854 229/426 |
