Hello: Using 4.6 (updating to 4.7 is my next project), I have set up two machines at two separate sites to that create a ipsec tunnel between them.
Both machines get a dynamic ip address for their internet connection from the ISP (comcast at one end, AT+T at the other). Both machines have the /etc/dhclient.conf file modified to include: request subnet-mask, broadcast-address, time-offset, routers; The line above is the ONLY line that is not a comment in either dhclient.conf file. Both machines have /etc/hostname.sk0 (the world facing interface) set up as: dhcp NONE NONE NONE (i think i don't need the "NONE"s, but that's the way I originally did it several months ago) I also have a "resolv.conf.tail" file, although given the fact that I have excluded "domain-name" and "domain-name-servers", I shouldn't need it. I have set up resolv.conf on each machine as I want it. BUT, one machine (the comcast one) works like I would expect.B It gets a dynamic ip address and does not change the resolv.conf file.B When i look at /var/db/dhclient.leases.sk0, i see that no information exists regarding dns servers or domain names. ON the other machine (the AT+T one) things are different.B It gets a dynamic ip address, but also updates the resolv.conf with a domain name and dns server from the dhcp server.B it also, as expected, then appends the contents of resolv.conf.tail to the new resolv.conf file, and also creates a resolv.conf.save file. Also, the data in /var/db/dhclient.leases.sk0 shows that the dhcp client received dns server and domain name info from the dchp server: .... B option domain-name-servers 192.168.1.254; B option domain-name "gateway.2wire.net"; .... (despite the dhclient.conf file specifically excluding that information from the request line) I can (sort of), make it do what i want by using supersede lines in the dhclient.conf file; but I don't understand what I have done different between the two machines.B As I said, both hostname.sk0 and dhclient.conf files are identical.B I have tried (on the problem machine) deleting resolv.conf.save and /var/db/dhclient.leases.sk0, and then rebooting (starting with a clean slate, I was thinking), but that does nothing. What am I missing? Thanks bye - ted
