How can I make IPSO get it's IP via DHCP?



The following isn't supported by Nokia, though there is plans to bring this functionality into a future release of IPSO.

Since IPSO 3.5 (or was it 3.6?), IPSO has contained a DHCP client within the OS. However, it is only activated upon initial installation and was primarily designed to make initial configuration easier. The system could pick up an IP via DHCP and be configured with Voyager without having to configure the system via the console cable. The DHCP server would have to issue a lease of at least one year for this to work.

However, it's relatively easy to configure IPSO to require a shorter minimum lease. You need to edit the file /etc/dhcpv4c-script. To do this, you must first mount the root file system read-write. You can do this with the command: mount -uw /Now you can use 'vi' to edit the file /etc/dhcpv4c-script. In this file, you will see the like:

MIN_LEASE=31536000 # -1 = 2147479953Change this line to read:

MIN_LEASE=-1Now you can force IPSO to fetch one of it's IPs via DHCP by adding the following to /var/etc/rc.local. eth-s2p1c0 is the interface I am getting my IP via DHCP with and replace your-nodename with the appropriate nodename for your system. The "sleep 15" gives IPSO a change to bring up interfaces first. The other commands that appear to twiddle the system nodename are necessary in my case because my cable ISP's DHCP server gives me a useless name

sleep 15 /sbin/dhcpv4c eth-s2p1c0 /bin/dbset active:hostname your-nodename /bin/dbset :save /bin/hostname your-nodename echo your-nodename > /var/etc/nodename

Note that FireWall-1 on IPSO currently does not support proper dynamic addressing, though that is scheduled for a later release as well.
