Hi, I apologize if this question is not appropriate for this list but... I just installed FreeBSD 4.0-CURRENT (19991226) on a box. I also recompiled the kernel so it would support SMP. All I basicly did is change two lines concerning SMP in the GENERIC kernel (I followed the handbook). The box is running just fine and I am very pleased with it. Here is the problem: I'm trying to firewall it using ipfw, when I issue the command ipfw add deny udp from any to any 1-2200 I get 00000 deny udp from any to any 1-2200 ipfw: setsockopt(IP_FW_ADD): Protocol not available I only changed two lines in the GENERIC kernel. Did I screw it up? I assumed packet filtering was enabled in the GENERIC kernel by default. Can anyone give me hints on how to fix this, or what this message means? I already RTFM and the stuff in the handbook (the man page looks very similar to the stuff that was in the handbook). Any help is greatly appreciated :) (PS: does the IPFILTER package work with FreeBSD? Because I'm used it and ipfw syntax is kinda anal. If so, has anyone tried it and successfully used it? Thanks.) -- Emre Yildirim Fingerprint = B16C EBA7 97FE EF2C 365F C4C4 54AA 3676 5E9E E10A DSS/DH 1024/4064: 0x5E9EE10A/0x2486FEBE To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
