I have tried to replace these lines from ipchains to work with shorewall. # /NFS requires 111/tcp (sunrpc/portmapper) and *all* UDP ports./ # ipchains -A input -p tcp -s $SUBNET -i eth0 -d 0/0 111 -j ACCEPT ipchains -A input -p udp -s $SUBNET -i eth0 -d 0/0 -j ACCEPT # /These ports are required by bootp, tftpd, and PXE./ # /There are also a handful of udp ports that need to/ # /be open,

I have a couple questions that I will submit separately. When I have IPchains running I can't get my samba box to show up in network neighborhood, but when I turn ipchains off the box shows up. What rules do I need to add for things to work properly? -- Raymond Norton Little Crow Telemedia Network 320-234-0270

I figured this out -- looks like 2.5.1p1 is now using ports < 1024 on the client side (wasn't before?). I had a ipchains rule to allow ACK packets to 1024:65535, which was good enough for <= 2.3.0p1 : #allow only ACK tcp packed ipchains -A input -j ACCEPT -i eth0 -s any/0 --dport 1024:65535 -p tcp ! -y So I added the following : #allow return from ssh connections ipchains -A input -j

Just a quick word - I spent two days trying to get Samba to work. The whole problem was a lack of knowledge about ipchains (firewall). It was part of the RH7.1 install package, and the medium security setting stops all tcp and udp traffic for a lot of ports, including those needed for NetBIOS (137-139) It is pretty easy to fix, the IPCHAINS-HOWTO is a good and humorous read, and by the end of

Hi all! I try to make port based routing, because a have two connections to the internet. My router is a "one disk floppy router for linux". It is a big router project www.fli4l.de. I try also to make a opt, it is like a plugin for this router. This project uses Kernel 2.2.19 compiled with libc5 (because it is small and you can use one floppy disk). At the moment, iproute2 is not

Hello, on my old system I''m using ipchains. Can anyone help me with converting rule /sbin/ipchains -A forward -j MASQ -s source_addr -d destination_addr 443 -p tcp to shorewall. I know that I can write eth0 source_addr to /etc/shorewall/masq file but I can''t found where I can specify the destination address. The reason for this is to allow one user (computer) access only to

[mod: This is the second time in a week that someone asks this question: is it a new attack? It sure looks to me like "userland" has completely locked up, but that the kernel is still working. As an isolated case, my diagnosis is: You probably have a bad block in your /bin/login program or something like that. When two people report this in a week, it's starting to become unlikely

To all those that wanted to know how I was filtering particular ICMP packets here is a few snippets from my firewall script which is based on one by Ian Hall-Beyer. I hope this helps you get started. Also note the output of the command: ipchains -h icmp Shawn Mitchell mentioned blocking all ICMP echos and especially broadcast echos. Perhaps he''d care to elaborate with a similar

I just recently installed OpenSSH 2.5.1p1 on a RH6.2 box (kernel 2.2.17). I run ipchains to do packet filtering, allowing incoming connections only to 22 and 80 (and some other ports for specific machines). I was able to run prior versions of openssh in this fashion (I've run it from the first release, I think). Upon installing 2.5.1p1 I found that my attempts to connect hang, here is ssh

Hello David, After some experiments and discussions I came to the following result concerning private NT-Box connecting to a LAN via ipchains and using all NETBIOS services (incl. domain-logon): Cross-subnet browsing with NETBIOS could only be done by a local master browser in the private net. I first thought of using Samba on the Linux router for that. But the Samba service would have to use

Dear Tinc Experts, I have been struggling for some time now, with Tinc pre3, and firewall rulesets and routing. I did once manage to get Tinc to work okay in a test-bed environment. I then tried to set it up for a 'real-life' setup and cannot get it to work properly. My real-life setup looks like this: Network A: 192.168.1.0 / 255.255.255.0 192.168.1.7 tap1 device gateway >

Hi Raymond, I also struggled 3 days to set up a direct connection between a RH7.3 box and a WinME box with a crossover cable for experiment and met with frustration. The setup of WinME box has no problem and it can connect to other Win boxes for file sharing. IP Address RH7.3 192.168.0.1 WinME 192.168.0.2 Ping started connecting but both boxes can't see each another. I also doubt

After the recent attacks on the major servers on the web my ISP has decided to stop all ICMP messages from his ISP. I have red the RFCs and it seems that he cant do that... As a result pings and traceroutes will not work. I need a friendly person out there to tell me a way to break the news to him that he has to allow ICMP packets through his network... any suggestions would be helpfull [mod:

I have an Asterisk PBX behind a 'manually-built' IPCHAINS firewall machine. Can anyone tell me what I need to allow/build QOS packet rewrites through this simple NAT barrier? What do I need to pass to IPCHAINS to let QOS out to the next outside network hop? I ask this, because I have been getting intermittent jitter from my provider (TELIAX), and since it seems near-impossible to

Can anyone tell me what the absolute minimally permissive ipchains rule would be to allow tinc to operate correctly between two hosts. If we were to presume each tinc host had a default-deny policy, what ipchains command(s) would allow tinc to do its thing? I've scanned the docs on the tinc site and not found the answer- sorry if I'm blind or dumb. Thanks, Patrick - Tinc:

Howdy, I tried tackling this on irc with Ivo, but I suspect that irc may really not be the best medium for technical discussions, so I'll reprise it here. I am trying to duplicate the "tinc from behind a masquerading firewall" example from the tinc web site: (home) <--> (masquerading firewall) <--> (office) 192.168.1.21 192.168.1.1/1.2.3.4
