Per user config for SpamAssassin with amavisd-new and cyrus-imapd
by David Huecking 26 Sep '04

26 Sep '04

Hi folks, maybe someone could give me a hint... I switched from: fetchmail->sendmail->sendmail.milter->Amavis->.forward->procmail->spamc(SpamAssasin)->INBOX which did global virus checking and per user spam checking with Bayes testing to fetchmail->postfix->amavisd-new->perl-spamassassin->cyrus-imapd which does global virus and global spam checking BUT NO PER USER spam checking, so without Bayes testing! :-( So the rate of unreconised spam did increase. I fiddled around with options in the /etc/mail/spamassassin/local.cf, but they were ignored because amavisd-new calls spamassin via perl interface and takes some SA parameters from the /etc/amavisd.conf (beginning with $sa_). I tried calling a SUIDed cyrus deliver (without SUID deliver hasn't got the right: deliver[3876]: connect(/var/lib/imap/socket/lmtp) failed: Permission denied) to user cyrus via .forward and a .procmailrc. The log said that lmtpd was called, but depending on the syntax of deliver in the .procmailrc the mail was delivered to the INBOX-file in /var/spool/mail or just vanished! One example for my .promailrc: :0 fw |/usr/bin/spamc -f |/usr/lib/cyrus/bin/deliver -e -a david -m user.david and the .forward: "|IFS=' ' && exec /usr/bin/procmail -f- || exit 75 #user" Could someone give me a hint using sieve or procmail for a per user SpamAssassin check?

Hello, I've a network printer declared as samba printer in my lnx machine. This server has 3 different ethx and a SuSefirewall2 running over. How can use from Lan 192.168.0.0/24 the samba printer with ip=172.168.0.200 ? Is it possible? Thanks Bye Paolo

If you are unhappy about what someone says, mail them directly, not to the list. whether "the bob" or "Paranoic_user" is wrong or right (or whether his opinions are wrong or right) is irrelevant. What is relevant is that this is someone you don't know who has taken the time to attempt to help someone he/she doesn't know from a bar of soap with a problem. Clarifying the problem is part of solving the problem. Clearly identifying what you are trying to achieve in your mail subject helps those who know abit about what you are trying to do identify mails that they may wish to respond to. Bickering wastes my time and yours. (P.S., thanks from someone who doesn't know you from a bar of soap for your input to my previous question) B

> I dont think so. I also don't think so. What I am interested to know however, is can multiple external interfaces be used? eg. eth0, has.valid.ip.add, eth0:1 has.valid.ip.add2, eth0:2 has.valid.ip.add3 eth1 192.168.0.1 eth2 10.0.0.1 eth0 (and sub ints) is external eth1 is DMZ eth2 is internal if I have 2 web servers internally and don't want to set up reverse proxy on squid (some people don't like this because of their sevrer logging) and want to be able to forward NAT'd connections to two servers in the DMZ, can I use eth0:1's IP for server1 and eth0:2's IP for server2 and set up my forward rules based on what address was requested (as you know I use SuSEfirewall2) doing this will be no problem. My concern comes in in that will the return traffic be nat's out the virtual interface that the connection came through? Bazz

SuSE Firewall2
by Travis Barlow 30 Apr '04

30 Apr '04

Hello I am hoping someone here may be able to answer a question for me. I have to set up a proxy for a network, and I want it to work along these lines.... User opens up their browser and are given a page that I assign them automatically from the proxy(or DHCP server) and then they can enter an account id and password that I provide. Anyone know if I can do this with SuSE Firewall2?? And how do I do it? Thanks Travis Barlow Gestionnaire de systémes et Sécurité Université Sainte-Anne "Paranoia is heightened awareness"

Thanks very much all. I think the long and short of it is I need to export my riules from SuSEfirewall2 and finally learn setting up IPtables/IPchains directly Bazz

Hi! Is it possible to filter with nat rules that I can access two servers on different IP's but with the same port? scenario: Inet | dev-ext (pppoe over dsl) | FW | dev-int (LAN) | servera.local.net:80 serverb.local.net:80 DNS names are provided by a service like dyndns.org. Philippe

allow EXCEPT (SuSEfirewall2)
by Barry Gill 30 Apr '04

30 Apr '04

Helo suse-security (little mail joke, sorry) I want to set up a rule in SuSEfirewall2 that allows all users from my LAN to browse or FTP from 192.168.0.0/24 to 0/0 This is easy and done. FW_MASQ_NETS="192.168.0.0/24,0/0,tcp,80 \ 192.168.0.0/24,0/0,tcp,21" My question is, I only want two internal addresses to be able to FTP and Browse to a specific FTP/WWW server. I cannot find any reference in SuSEfirewall2 to include an exclusion in the above line. I was thinking something like: FW_MASQ_NETS="192.168.0.0/24,0/0!200.200.200.211,tcp,80 \ 192.168.0.222,200.200.200.211,tcp,80" Any idea how to do this, or should I create all my forwarding rules directly using iptables?

SuSE Firewall2 HOWTO or FAQ
by Anthony Brock 29 Apr '04

29 Apr '04

I've been monitoring discussions around the SuSE Firewall2 for some time. As a recent convert from RH 8, I've been confused from "day one" concerning how to configure this particular component. This is even after I've ready through the configuration file several times. To be honest, I'm not even certain how I could bypass this to explicitly specify the IP table rules. However, discussions on this list (and notes within the configuration file) indicate that this and many other options are available. Is there a general "HOWTO" or guide concerning this tool? Even better, is there a cookbook or FAQ? Thanks! Tony
