Hi. I have just decided to upgrade my lovely Bering firewall to take advantage of uCLib. I have put together my Bering 2 floppy and almost everything works fine! The fly in the ointment is the connection to my ISP. I am on BigPond Cable and I use udhcpc and BPALogin in my working Bering floppy. Udhcpc doesn't seem to have been recompiled for uCLib so I am using dhclient and BPALogin in my uCLib version.
The oddness is that using udhcp I get a particular IP Address (call it IPudhcp) but with dhclient I get a totally different IP (call it Ipdhclient). But my hardware is the same so my MAC addresses don't change. This is repeatable ie if I boot with my udhcp disk, I get IPudhcp every time, then if I boot my dhclient floppy I get IPdhclient every time. This seems odd to me because all I have read indicates that IP addresses might be allocated on the basis of stored MAC addresses, not some characteristic of the dhcp client. The reason this is an issue is because BPAlogin for the dhclient floppy won't login! It says it can't find the authentication server. The settings are the same as for the udhcp floppy and I use the dotted quad IP address to point to the server. However, I find that if I turn my modem off for about 5 minutes with my router off, then turn the modem back on, and reboot the router, it will connect. This sort of behaviour is typically associated with clearing the MAC address stored by the modem, but I don't see why it makes any difference to me because my MAC Address doesn't change! Then after about 5 minutes my connection disappears! When I look at my Shorewall logs following the disconnection I find that there are entries showing rejection of connections from the Authentication server to port 5050 (which is the BigPond heartbeat port) but to Ipudhcp, not IPdhclient! So the rejection logs show that the authentication server has tried to contact my router on the IP address that would have been allocated if I had used udhcpc! And because the connection was rejected, I am logged out! This is all very weird. It appears that dhclient is connecting ok using the allocated IP address but 'something' in the Auth server is still associating my MAC address with the IP address I would have been given if I was using udhcp. I am after any advice anyone can offer on what might cause this or how to get around it. Is there any connection between MAC Address and the dhcp client? Does the dhcp client send a MAC address to the auth server? I would like to try another dhcp client and I see Pump has been recompiled so I will try that first. Lynn, are you planning to recompile udhcpc because I would like to try that as well. Thanks folks, as usual!
