RE: spamassassin question [with blacklist question]
by Brian Densmore 26 Oct '04

26 Oct '04

The problem there is it is now configured and working. Installing a new exim and a new SA would mean reconfiguring the software due to changes in syntax, options, etc. In other words installing the current SA over top of SA 2.2 would break a working setup. I'd rather play with the one that is working and learn more about SA first, so that when I upgrade I will have some knowledge of what the heck it is I'm doing. ;') I'm not saying that I feel the current SA or exim is the best thing since sliced bread with peanut butter, honey and marshmallow on it, just that it would mean breaking something I don't yet understand well enough to fix quickly and easily on my own.

Blocking IPs from the FW [was RE: spamassassin question [with blacklist question]]
by Brian Densmore 26 Oct '04

26 Oct '04

By the way, anyone have a take on what kind of performance hit this will take on a server? So far I have 22 addresses or address ranges blocked in my blacklist. And is there a better way? Most of the attempts have been to try to gain root access via ssh, which root isn't allowed to ssh anyway, so this would always fail. Some are for non-existent users.

Well SA 2.2 is catching about 155 of my spam. I may add some customization to see if I can't improve it a bit. I'll wait a bit before upgrading.

You might want to add some of the spamassassin rules from here http://www.rulesemporium.com/rules.htm . The RulesDuJour script works very well for me.

You're right! I had started to snooze by the time I got to the end there. Maybe it was a trait of all Roosevelts. I do like most of what I read about Teddy, but sometimes he was over the top and too cavalier. He is lucky he was successful in most of what he took on. I saw an old Sean Connery movie, "The Wind and the Lion," a few weeks ago. Brian Keith was playing Teddy. I don't think the Secret Service would allow a lot of what he did to go on today. I did think it was cool that Teddy was testing the new Henry repeating rifles and making/demanding changes to the design. Back then, campaigns were run from train cars on whistle-stop tours.

I happen to like apache 1.3 and see no problems with the 2.4 kernel. The SA version in stable is 2.2 so it's quite out of date. Then there is exim using version 3.36. The thing I like about stable is that the security patches happen first in stable. Having been hacked once, I tend to be a bit more conservative these days (*and by the way, I've also been seeing a lot of those scripted hack attacks). At least where my "production" software is concerned. At home I run testing/unstable. Not sure how I accomplished that, but there it is. * I've added some code to my firewall rules to read in my personal blacklisted ipaddresses from a file and make drop rules out of it. Now I need to write a little script to put in cron to scan my logs once a day and extract ip-addresses that are attempting to login and add them to the blacklist and restart the firewall. something like: MYADDR=xxx.xxx.xxx.xxx BLACKLIST=/etc/blacklist.txt FWSCRIPT=/etc/init.d/firewall.sh cat /var/log/auth.log |grep -i failed\ password | cut -d\ -f11 |uniq > nuiq.txt if [ -e nuiq.txt ] then while read ipaddr do if [ $ipaddr ne $MYADDR ] ; then echo $ipaddr >> $BLACKLIST fi done < nuiq.txt $FWSCRIPT restart fi My only problem here is sometimes I need to use 'cut -d\ -f11' and sometimes 'cut -d\ f12'. Sometimes I have to do both in the same file. So I guess it's time to pull out the sed pocket reference I have and learn something in there to help. It's because of the way the date is being posted to the log file: Oct 9 ... Oct 10 ... So I get one extra delimiter when the date has one digit. I'd also like to be able to skip the saving of the list to a file step. Alas my script skill are insufficient for the task. Also I might soon need to use a case or some other control method to ignore perhaps a half a dozen ipaddresses or even a range of ipaddresses for other users of the system.

Brian, I nominate you for Longest .sig. This also works for one of my theories; Roosevelt was a blow-hard. It's quite possible that the House and Senate agreed w/ his plans out of sheer boredom and a fight-flight instinctual response. Lucky for us that the war finally encouraged investment from the people in charge of spending real and borrowed money. <flame-retardant suit on> Brian Kelsay >>> "Brian Densmore" <> 10/26/04 12:34PM >>> "The President is ..... than about any one else." --Theodore Roosevelt, Kansas City Star, May 7, 1918

PostNuke site cracked
by Brian Densmore 26 Oct '04

26 Oct '04

Anyone who downloaded PostNuke between Sunday and Tuesday need to get rid of it and re-download it. Their site was cracked and an altered PostNuke download posted. http://www.newsforge.com/article.pl?sid=04/10/26/1356232 Brian "The President is merely the most important among a large number of public servants. He should be supported or opposed exactly to the degree which is warranted by his good conduct or bad conduct, his efficiency or inefficiency in rendering loyal, able, and disinterested service to the Nation as a whole. Therefore it is absolutely necessary that there should be full liberty to tell the truth about his acts, and this means that it is exactly necessary to blame him when he does wrong as to praise him when he does right. Any other attitude in an American citizen is both base and servile. To announce that there must be no criticism of the President, or that we are to stand by the President, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public. Nothing but the truth should be spoken about him or any one else. But it is even more important to tell the truth, pleasant or unpleasant, about him than about any one else." --Theodore Roosevelt, Kansas City Star, May 7, 1918
