ipt_MARK missed? [message #16173]

Have CentOS 5 (x86_64), latest OpenVZ kernel and tools, VPS based on centos-4-x86_64-minimal template.

Trying to set iptables modules to vps:

Quote:

vzctl set 200 --iptables "iptable_filter iptable_mangle ipt_limit ipt_multiport ipt_tos ipt_TOS ipt_REJECT ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_LOG ipt_length ip_conntrack ip_conntrack_ftp ip_conntrack_irc ipt_conntrack ipt_state ipt_helper iptable_nat ip_nat_ftp ip_nat_irc ipt_MARK"

But the error acquires:

Quote:

Warning: Unknown iptable module: ipt_MARK, skipped
Bad parameter for --iptables: iptable_filter

How to fix this?

Are you sure that this module is loaded on the Host Node?

Sorry, I was err,
it looks like this error occured because "vzctl --iptables" have no support for ipt_MARK module.

However this parameter is used to restrict access to iptable modules inside VE (by default all iptables modules that loaded in host system are accessible inside VE).

Could you please explain, why you want to restrict access to iptable modules?

Thank you,
Vasily Averin

Hi Vasily,

seems that after a long time... I can recycle this thread Wink

I'm running into the same prob.

I like to use MARK within the VE. At the VE0 the module has been loaded and is in use - so it works there...

If I try to use it inside the container:

/sbin/iptables -t mangle -I PREROUTING -p tcp -d MYHOST --dport 3690 -j MARK --set-mark 1
FATAL: Could not load /lib/modules/2.6.27.21-briullov/modules.dep: No such file or directory
FATAL: Could not load /lib/modules/2.6.27.21-briullov/modules.dep: No such file or directory

Yes... I use 2.6.27.21-briullov...
