iptables

Hello all, Has anyone played with ethernet bridging with bridges/ebtables rate limiting and shaping augmenting iptables handling firewalling on a cpanel box? I've had great success doing this in the past buliding kernels with full netfilter support compiled in (including ebtables + friends)...

Could any one provide me the shell script to check the iptables status if its stopped mail should be send. Appreciate any response regarding scripts.

Hi Everyone I am installing csf however I get the following iptable error, please can someone tell me what it means Error: iptables command [/sbin/iptables -v -I OUTPUT 2 -i eth0 -j GDENY] failed, at line 383

A couple days ago, my server seemed to crash while re-starting csf. I had to get my DC to disable the firewall and re-boot from console. Since then, although csf and lfd seem to be running OK and are configured correctly, it seems as if something is causing iptables to flush appx every 5...

Hi Guys, I am sure we all go through the same woe's everytime we see the name 'Security Metrics' invovled with our clients business. I am battling them over this lovely issue Since I have been unable to determine how one is supposed to switch this over, I was wondering if anyone could let me...

Tired of the spam flooding this month I aplied several rules to the mail server as - Chirpy´s Exim dictionary attack ACL - RBL - Limiting the recipient numbers per e-mail - Modsecurity to prevent Bcc injection in php forms. These things help me a lot in stoping spam and decreasing...

Anyone know what could take APF so long to start? It stops fine (service apf restart) but starting up again takes forever. I have about 12 blocks of 8 IP's on the server (reseller), APF v 0.9.6 The deny list is almost empty, only 5-6 IP's listed. The server is fast (dual xeons / 4GB memory)...

I keep getting emails sent to me at [email protected], with the contents being just iptables: Memory allocation problem Repeated loads of times Why is this and how can I stop it?

I noticed that a lot of apache sessions were showing with the status of '...reading...'. If I checked the source of these, they were all coming from one IP address. I therefore used the following command: iptables -I INPUT -s XXX.XXX.XXX.XXX -j DROP (where XXX.XXX.XXX.XXX is the IP...

Hello there, I have recently ordered a new dedicated server from Ezzi.net, it's great. I've just got this one and VERY annoying problem. It seems that iptables has messed up after I did a kernel upgrade. I get the following error in an email about every 5 minutes: iptables v1.2.11: can't...

Hi As I saw on "A Beginner's Guide to Securing Your Server", it is recommended to use APF to configure a firewall, i would like to now if it is possible to use IPTABLES to apply such rules instead? May it affect other services to work properly? Thanks.

I was just wondering, does cPanel have anything in it that automatically restarts IPTables every night at around 2AM? For whatever reason, everytime I kill iptables it restarts itself at about 2AM. When it does this it automatically blocks ports >1024 even though the iptables-config says to...
