Hi Harald, Just tested it on top of 2.4.25, like this : KERNEL_DIR=/usr/src/linux-2.4.25-pomng ./runme --batch extra and I got a few problems : - first, I didn't find how to specify where my iptables sources is installed, so I had to enter it by hand each time I restarted it. I did not find any env variable in the perl code, and I must say that my understanding of perl is, hmmm.. very limited. - ROUTE and TRACE told me : "unable to find ladd slot in src /usr/src/linux-2.4.25-pomng/./net/ipv6/Makefile" I think they wanted to add a line in the Makefile but didn't find the right place to do so. BTW, is there a way to install a patch only for ipv4 or for ipv6 like before ? - I observed usual conflicts : present 'CONNMARK' conflicts with to-be-installed 'connbytes' present 'raw' conflicts with to-be-installed 'conntrack-seqfile' present 'CONNMARK' conflicts with to-be-installed 'conntrack_arefcount' - and finally, trying to apply conntrack_locking litterally killed my box in out of memory within a few tens of seconds (I could not even run ps) : Out of Memory: Killed process 9841 (runme). Out of Memory: Killed process 9970 (ps). Out of Memory: Killed process 159 (bash). Out of Memory: Killed process 158 (bash). Since conntrack_locking needs conntrack_arefcount which could not be applied, I wonder if there's some problem resolving dependancies. I've not gone further yet. Do you need more info ? There may be some things I did wrong, do not hesitate to tell me ;-) Cheers, Willy
