I asked how do you get sendmail working in Solaris 2.2. Many folks said
that I didn't have 'mailhost' defined in my /etc/hosts file, and they were
right. Turns out that I needed to do a bit more.
This is a step-by-step on how I setup IPCs on our campus. The sendmail
stuff is near the end of the outline. Since I just came up with this, I
might be doing something extra that doesn't really need to be done. Feel
free to email me and give me suggestions/corrections for this list.
Perhaps something like this should go into the Sun FAQ????
Note that I don't setup the workstations here using NIS+, but the
procedure should work even if you use it. There are notes in here about
using netmasks, etc. You should configure this list for your own site.
Many thanks to all the folks that sent me suggestions.

Name conventions used in this document
planet The machine getting Solaris 2.2 installed on it. star The local name server and mailhost. .system.edu The local DNS domain.
I. Boot the Solaris 2.2 CD-ROM.
A. Shutdown the system.
1. SunOS 4.1.x users should login as root and type
shutdown -h now
2. Solaris 2.x users should login as root and type
init 0
B. Insert the CD disk into the caddy and put the caddy into the drive.
C. Boot from the CD-ROM.
1. If the prompt looks like a ">", you will probably have to type "new" to get to the new command mode of the PROM monitor. You should get an "ok" prompt.
2. At the "ok" prompt type
boot cdrom
The system should boot from the CD-ROM drive. On some systems you may have to type
boot sd(0,6,2)
D. The system takes about 10 minutes to boot up from CD. The system will say something like WARNING: clock gained 184 days - - CHECK AND RESET THE DATE! Ignore this message.
II. Install Solaris 2.2.
A. You will be asked for the hostname of your machine. Type it in.
Hostname: planet WARNING: There was a bug in the Solaris 2.1 install procedure that chopped the hostname after the first 9 letters. This may not have been fixed in Solaris 2.2. DO NOT use a fully qualified domain name (like planet.system.edu), but rather just use the first part of the name (like planet). Entering a fully qualified domain name could render the computer unusable later in the install process and requiring an OS reinstall.
B. You will be asked
Will this system by connected to a network?
No >Yes
C. You will be asked
What is your Internet Protocol (IP) address?
IP address: 130.184.71.23
D. You are asked if the information is correct. Answer yes if it is, or say no and go back and fix it.
E. You will be asked
Do you want to configure this system as a client of a name server? If so, which name service do you want to use?
NIS+ Client NIS (formerly yp) Client >None - use /etc files F. You will then be asked
Does this workstation's network have sub-networks?
No >Yes
G. You will then be asked for the netmask value. The default netmask is correct.
Netmask: 255.255.255.0
H. Now you get the chance to review the information you entered and to go back and change it if you need to.
I. You will be asked
What is your geographic region?
Africa Western Asia Eastern Asia Australia / New Zealand Canada Europe Central America South America >United States other - offset from GMT other - specify rules file
J. You will be asked
What is your time zone?
Eastern >Central Mountain Pacific Yukon East-Indiana Arizona Michigan Samoa Aleutian Hawaii none of these - return to regions menu
K. You will be asked
What is the current date and time?
Year (4 digits) 1993 Month (1-12) 05 Day (1-31) 14 Hour (0-23) 15 Minute (0-59) 24
L. You will get a chance to review the information you have typed in.
M. The system will pause for a minute then you will be asked about what kind of installation you want to do.
( Quick Install... ) ( Custom Install... ) ( Upgrade... ) ( Exit Install... ) ( Help... )
Choose the Quick Install.
N. Next, you must define the installation configuration. The choices are:
Entire distribution: 284.18 MB Developer system support: 210.31 MB End user system support: 126.44 MB Core system support: 44.37 MB
Sun IPC's with 200 megabyte hard disks should choose the end user system support package.
O. The install program now attempts to autoconfigure the partitioning of the hard disk(s). Sun IPC's with one 200 megabyte disk drive have the partitions auto-configured like this:
File system Size (MB) Disk Space used / 14.00 c0t3d0 68% swap 39.00 c0t3d0 0% /opt 22.00 c0t3d0 39% /usr 120.00 c0t3d0 37%
Select "Begin Install"
P. The installation will begin. The computer will read from the CD-ROM for about 45 minutes and reboot itself.
WARNING: If you typed in a fully qualified domain name for the hostname of the machine, the computer may hang when it reboots. There is a bug in the install procedure for Solaris 2.1 that truncates this information to 9 letters when you type it in. This may not have been fixed for Solaris 2.2. Usually, you will see warnings that look like
le0: bad address
during the boot procedure if you typed in a fully qualified domain name.
III. Configure Solaris 2.1
A. When the computer finishes booting, you will be asked
What is your root password?
Pick a good root password and type it in.
B. After few minutes the login prompt will appear. Login as root.
C. Start up OpenWindows if you like. It can make some things easier to do. Type
/usr/openwin/bin/openwin
If you do, and you haven't ejected the CD-ROM yet, you're given the chance to eject the disk. You may also eject the CD-ROM at any time (provided that your present working directory is not one of the ones on the CD) by typing
eject cd
D. Setup domain name service.
1. Copy the configuration file that uses files, not NIS to the nsswitch.conf file.
cd /etc cp nsswitch.files nsswitch.conf
2. Edit the nsswitch.conf file and make changes so that DNS will be consulted. Add the word "dns" after the word "files" on the hosts: line.
E. Check the /etc/defaultrouter file. The install procedure does not create it, so you probably will have to. The existence of this file prevents routed from running. The file should contain only the IP address of the router on your subnet. Most routers on this campus have an x.x.x.5 IP address. An example looks like this:
130.184.71.5
F. Edit the /etc/hosts file. It should contain entries for localhost, the machine you are working on, and the name server (although it is not listed as a name server in this file) and the machine that you will use as a mail host. An example:
# # Internet host table # 127.0.0.1 localhost loghost 130.184.71.23 planet.system.edu planet 130.184.7.103 star.system.edu star mailhost
G. Check the /etc/netmasks file. It should already be set up correctly. It should contain a line that looks like this:
130.184.0.0 255.255.255.0
H. Check the /etc/resolv.conf file. An OS installation does not create this file, so you will probably have to do it. It should contain these lines:
domain system.edu nameserver 130.184.7.103
Some system administrators choose to add other name servers to the list like this:
nameserver 130.184.64.233 nameserver 192.35.82.2
I. Setup sendmail:
1. Kill the old sendmail daemon.
ps -ef | grep sendmail kill <PID of sendmail>
2. Setup your NIS domain name.
domainname .system.edu domainname > /etc/defaultdomain
3. Setup the machine to use the mx version of sendmail for Internet use. The default sendmail is not the mx version.
cd /usr/lib cp sendmail sendmail.nomx rm sendmail ln -s sendmail.mx sendmail
4. The mailbox has moved under Solaris 2.x. Setup a link so that programs like elm and pine can find the new mailbox.
ln -s /var/mail /var/spool/mail
5. Use the main mail distribution configuration file, not the default subsidiary mail distribution file.
cd /etc/mail cp sendmail.cf sendmail.cf.old cp main.cf sendmail.cf
6. Change the values of some of the macros in the sendmail.cf file.
a. Comment out Dj$m on line 26 and uncomment Dj$w on line 30.
b. Change DMsmartuucp on line 34 to DMether
c. Setup the DR and CR macros on lines 37 and 38 so that they reference the mailhost defined in the /etc/hosts file.
DRmailhost CRmailhost
d. Make entries for the w and m macros after line 77 (after the comments that talk about the Dm and Cm lines).
Dmplanet.system.edu Dwplanet.system.edu
7. Mail won't work until you restart the sendmail daemon, either by rebooting the machine or by restarting it manually:
/usr/lib/sendmail -bd -q1h J. Reboot the machine. Type
init 6
K. Test mail (sending and receiving) if you set up your machine to use mail.
That's it!
