I am getting mixed success with my wireless connection sharing. I am finally figuring out certain aspects that need to be handled to get it working but one baffles me still.
I get a modem connection on box 1 which is ad-hoc wireless connected to box 2. After the connection, box 1 can use the internet OK but box 2 doesn't get DNS - it can only use the internet if IP addresses are used while site names lead to unknown host messages. I have checked my routing tables and they are fine. I also have iptables setup to NAT. I am just not able to get name resolution on box 2 from box 2. At the moment, to get it working I have had to manually add the DNS IP on box 2 assigned by the modem connection. How do I get name resolution to work? I am not running a local DNS (and would prefer not to). I SHOULD be able to use the DNS settings of box 1 to get name resolution on box 2. What settings need to be looked at on which box to get this working? It HAS worked before but I have no idea how/why - while now it doesn't. My iptables-save output is: # Generated by iptables-save v1.2.5 on Thu Nov 28 10:45:49 2002 *filter :INPUT ACCEPT [2753:2158267] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [3352:376728] -A INPUT -i eth0 -p udp -m udp --sport 68 --dport 67 -j ACCEPT -A INPUT -i eth0 -p tcp -m tcp --sport 68 --dport 67 -j ACCEPT -A INPUT -i eth0 -p udp -m udp --sport 67 --dport 68 -j ACCEPT -A INPUT -i eth0 -p tcp -m tcp --sport 67 --dport 68 -j ACCEPT -A INPUT -i eth0 -p udp -m udp --dport 53 -j ACCEPT -A INPUT -i eth0 -p tcp -m tcp --dport 53 -j ACCEPT -A INPUT -i lo -j ACCEPT -A FORWARD -s 192.168.0.0/255.255.255.0 -j ACCEPT -A FORWARD -i eth0 -j ACCEPT -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT COMMIT # Completed on Thu Nov 28 10:45:49 2002 # Generated by iptables-save v1.2.5 on Thu Nov 28 10:45:49 2002 *nat :PREROUTING ACCEPT [202:12816] :POSTROUTING ACCEPT [464:37631] :OUTPUT ACCEPT [468:37967] -A POSTROUTING -s 192.168.0.0/255.255.255.0 -j MASQUERADE -A POSTROUTING -s 192.168.0.0/255.255.255.0 -o ppp0 -j MASQUERADE COMMIT # Completed on Thu Nov 28 10:45:49 2002 My box 1 routing table contains: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 128.211.132.5 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 128.211.132.5 0.0.0.0 UG 0 0 0 ppp0 Anyone have any wisdom to put forth? On box 2, how do I setup DNS (with linuxconf?) Right now, I have box 1's IP as its DNS (192.168.0.1). This is also its gateway. praedor __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable. Sign up now. http://mailplus.yahoo.com
