I was reading the netfilter docs hosted at samba.org for setting up masquerading on a linux box for a dynamic ip ppp connection....there were 3 commands in section 4.1 (I just want masquerading...help!), but when I tried them out on my stock redhat 7.2 box, I got these error blocks for the modprobe and iptables commands respectively:
Note: /etc/modules.conf is more recent than /lib/modules/2.4.2-2/modules.dep /lib/modules/2.4.2-2/kernel/net/ipv4/netfilter/ip_tables.o: init_module: Device or resource busy Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters /lib/modules/2.4.2-2/kernel/net/ipv4/netfilter/ip_tables.o: insmod /lib/modules/2.4.2-2/kernel/net/ipv4/netfilter/ip_tables.o failed /lib/modules/2.4.2-2/kernel/net/ipv4/netfilter/ip_tables.o: insmod iptable_nat failed Warning: wierd character in interface `-ppp0' (No aliases, :, ! or *). Note: /etc/modules.conf is more recent than /lib/modules/2.4.2-2/modules.dep /lib/modules/2.4.2-2/kernel/net/ipv4/netfilter/ip_tables.o: init_module: Device or resource busy Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters /lib/modules/2.4.2-2/kernel/net/ipv4/netfilter/ip_tables.o: insmod /lib/modules/2.4.2-2/kernel/net/ipv4/netfilter/ip_tables.o failed /lib/modules/2.4.2-2/kernel/net/ipv4/netfilter/ip_tables.o: insmod ip_tables failed iptables v1.2.1a: can't initialize iptables table `nat': iptables who? (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. and I really can't work out exactly what could be wrong here.....if modprobe is setting the parameters, I would assume they would be correct....not sure what the init_module: device or resource busy is about though.... I am (probably obviously) something of a newbie here and have spent the last month or so (on and off) wading through docs to make good on my promise to my flatmate that I would be able to network our machines and set up ipmasquerading on my linux box....if you can give me any assistance in my quest to keep my word good, I would be very appreciative.... thanks heaps in advance. -dionysus
