How to configure network on ILOM

Bala — Thu, 27 Oct 2011 05:00:26 +0000

In my previous post I explained Switching between ALOM and ILOM shells. Here we will configure network interface on ILOM

The following steps will configure the network settings for the ILOM.
1) Connect a terminal to the ILOM serial management port.
2) Power up the server.
3) When prompted, login into the ILOM as root:
login: root password: ***********(this should be the default password and can be confirmed by consulting the documentation shipped with the server).
4) Set the network details for the ILOM:
> set /SP/network pendingipaddress= 10.89.14.145 > set /SP/network pendingipdiscovery=static > set /SP/network pendingipgateway= 10.89.14.1 > set /SP/network pendingipnetmask= 255.255.255.0 > set /SP/network commitpending=true
The above mentioned IP Address is example

5) Try opening an SSH connection to the ILOM in order to confirm that the setup was successful.

How to install and configure sSMTP on CentOS / Fedora / Redhat

Bala — Fri, 09 Sep 2011 19:42:00 +0000

sSMTP is alternative to Sendmail. sSMTP is a send-only sendmail emulatorfor machines which normally pick their mail up from a centralized mailhub (viapop, imap, nfs mounts or other means). It provides the functionality requiredfor humans and programs to send mail via the standard or /usr/bin/mail useragents. It is used to send mail to externalemail address after authentication with valid mail account.

Download & Install

# rpm -Uvhhttp://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm

# yum -y install ssmtp

Now we will editthe ssmtp configuration file.

# cd /etc/ssmtp

# vim /etc/ssmtp/ssmtp.conf

Here is the custom configuration

MailHub=mail.techgyaan.org:25 # SMTP server hostname and port

UseTLS=NO # Secure connection (SSL/TLS)

FromLineOverride=YES # Force the From: line

Hostname=mail.techgyaan.org # The name of this host

RewriteDomain=mail.techgyaan.org # The host the mail appears to be coming from

Root=Bala # Redirect mail for root@ to postmaster@

AuthUser=bala@techgyaan.org # Your DreamHost mailaccount

AuthPass=myemailpassword # The password for the mail account

Now let’sconfigure the Aliases

# vim /etc/ssmtp/revaliases

root:alerts@techgyaan.org:mail.techgyaan.org:25
Postmaster:alerts@techgyaan.org:mail.techgyaan.org:25
Bala:bala@techgyaan.org:mail.techgyaan.org:25

If you would like to change the “From“Display Name, edit the /etc/passwd and modify theuser alias

# vim /etc/passwd

alerts:Alerts:507:507::/home/alerts:/bin/bash
bala:BALA:505:506::/home/bala:/bin/bash

postmaster:POSTMASTER:505:506::/home/postmaster:/bin/bash

Before we start using sSMTP lets stop thesendmail which is default installed on all Linux distribution.Stop sendmailservice to start after reboot

# service sendmail stop
# sudo chkconfig –levels 2345 sendmail off

Move or replace the sendmail and thencreate
a symbolic link for sSMTP to sendmail with authentication

# mv /usr/sbin/sendmail/usr/sbin/sendmail.orig

# ln -s /usr/sbin/ssmtp/usr/sbin/sendmail

We all done with the installation andconfiguration let’s send a test mail to internal & external email addressusing sSMTP.

echo”Sending Test mail to external & Internal email address”| mail -s”This is the test message using sSMTP” bala@techgyaan.orgbala@gmail.com
