Edit /etc/resolv.conf
Mvmail requires a /etc/resolv.conf file that contains the domain names and IP addresses for the Profits Plus server and any other DNS servers in the customer’s network. Normally the mvmail installation will send our MVS /etc/resolv.conf file as a starting point. However, if the machine already had a /etc/resolv.conf file then the MVS version would have been sent as /etc/resolv.mvs and you will have to make sure their resolv.conf file contains the same lines as the MVS version.
Edit their /etc/resolv.conf file to match their domain names and IP addresses. You may have to talk to the customer’s network administrator to get the required information.
Edit S98mvroute file
You may or may not need to do this. These instructions tell you how to find out.
In order for email to work, SCO needs to know the IP address of the default network router. This is sometimes called the "default gateway". This is loaded at boot time in the startup script /etc/rc2.d/S98mvroute (a sample is at the bottom of this page).
Note: We don’t use the S90iproute file that comes with SCO because it can hang if the remote machine at the ip address isn’t up when the Profits Plus server is booting. Our S98mvroute script only tries to connect to ip addresses that can be pinged successfully at boot time. If the file /usr/internet/etc/sco_ip/routes doesn’t exist then you know the S90iproute script isn’t used at boot time (and that’s a good thing).
Caution: The network connection to the default router might already be in some other startup script on the Profits Plus server so you will have to do the following test to find out.
Grep all the existing startup scripts to see if they already have established a network connection to a default router. Use this grep command to find out.
cd /etc/rc2.d
grep “add default” S*
If the grep returned an active startup script line something like the one below, then they already have a default router connection and you won’t have to add the S98mvroute script:
/etc/route –n add default 192.168.100.20
How to install the S98mvroute script
• Modify the /u/mvs/sco/bin/S98mvroute script so that it contains the correct IP address for the customer’s default router.
• The version of S98mvroute in the /u/mvs/sco/bin directory has no effect. It is there just for reference.
• Copy the modified /u/mvs/sco/bin/S98mvroute script to /etc/re2.d
• Execute the S98mvroute script from the command line so you won’t have to re-boot the computer.
This is a sample S98mvroute script showing where you will have to modify it with the customer’s default router ip address (highlighted in yellow).
