How to change IP adress of mailserver in Solaris?
Hi all,

Our IT changes mailserver's IP address and I am trying to change it but with no success.
I am running Solaris 10.
I changed IP address of mail server in /etc/hosts file, performed make sendmail.cf but server still sends mais using old IP.

Quote:
-bash-3.00# more /etc/hosts
#
# Internet host table
#
::1 localhost
127.0.0.1 localhost
10.15.208.88 analizator analizator.com loghost
10.10.1.86 mail.azerfon.az mailhost
10.75.58.83 sms.narmobile.az
-bash-3.00#

Can anyone let me know which actions have to be done to change IP address of mail server please?

Thanks in advance,
Roman

Do you have a smarthost defined in your sendmail configuration? If so, change it there and restart sendmail.

If you use the *.mc macro files, look for a line like
Code:
define(`SMART_HOST', mail.example.com)dnl

After changing sendmail.mc, don't forget to run make

Otherwise look into the sendmail.cf file and find a line like
Code:
DSmail.example.com

and change accordingly.

Hi Hergp,

Thanks for the answer.
We've changed only IP address of mail server, its name still same.
Here it is what i have in sendmail.cf file:

Quote:
# "Smart" relay host (may be null)
DSmail.azerfon.az
DSsms.narmobile.az
and my hosts file:

Quote:
-bash-3.00# more /etc/hosts
#
# Internet host table
#
::1 localhost
127.0.0.1 localhost
10.15.208.88 analizator analizator.com loghost
10.10.1.86 mail.azerfon.az mailhost
10.75.58.83 sms.narmobile.az
-bash-3.00#
after changing IP in hosts file I restarted mail server with commands:

Quote:
399 svcadm disable svc:/network/smtp:sendmail
400 svcadm enable svc:/network/smtp:sendmail
And even restarted server, but issue still remain...

First, does
Code:
getent hosts mail.azerfon.az
getent hosts sms.narmobile.az

print the correct IP addresses?

Further, I don't think, repeating the DS macro is the correct way to define multiple smarthosts. Afaik it should be
Code:
DSmail.azerfon.az:sms.narmobile.az

I changed as u said:

Code:
DSmail.azerfon.az:sms.narmobile.az

Then run command:

Code:
-bash-3.00# /usr/ccs/bin/make sendmail.cf
`sendmail.cf' is up to date.

and:

Code:
-bash-3.00# getent hosts mail.azerfon.az
10.10.1.86      mail.azerfon.az mailhost
-bash-3.00# getent hosts sms.narmobile.az
10.75.58.83     sms.narmobile.az
-bash-3.00#

When I am trying to send test mail using

Code:
echo "swdfsdf "  | /usr/bin/mailx -s "MSS04 Clear Code 1 > 95" rrosliy@azerfon.az

and doing snoop in other window for 10.10.1.86 I can see that nothing happens:

Code:
-bash-3.00# snoop -r 10.10.1.86
Using device /dev/ce (promiscuous mode)

But if I am doing snoop to old mailserver's IP, I can see:

Code:
-bash-3.00# snoop -r 10.13.44.16
Using device /dev/ce (promiscuous mode)

So it means that mailx using old IP...
Any idea?

Thanks.

Check, if any other files in /etc/mail contain the old IP address (10.13.44.16). /etc/mail/mailertable would be a candidate for this.

And BTW: you don't have to run make, when you edit sendmail.cf directly. It is only used to compile the sendmail.cf file from sendmail.mc.

Code:
-bash-3.00# pwd
/etc/mail
-bash-3.00# grep 10.13.44.16 *
-bash-3.00# 
-bash-3.00# 
-bash-3.00# find . | xargs grep '10.13.44.16'
-bash-3.00# 
-bash-3.00# 
-bash-3.00# 
-bash-3.00# grep 10.10.1.86 *
-bash-3.00# find . | xargs grep '10.10.1.86'
-bash-3.00#

I think that IP address specified in some other place, not in /etc/mail.
