Ussualy for editing configuration at command line interface on linux server i’m using pico as favorite editor 
. Because pico editor is the best and simple editor for me. Many people around me are using pico instead too of other editor like vim which come with centos.
As you know, pico is not come together with centos and you may refer to this article and apply to your server.
yum install nano
cd /usr/bin/
ln -s nano pico
export EDITOR=”pico”
Now, try to pico and you will be able to use it. And pico can be using on My CentOs

Introduction
SNMP is the Simple Network Management Protocol. You’ll find it on the more expensive routers, switches, and gadgets. It can allow you to keep an eye on various machines with tools like Nagios and Cacti. Watch for spikes of network activity, see how much memory is used in a day’s time, or do some customization and compare spams to hams.
A workstation can be watched, too. And that’s what I hope to show here.
I’m assuming you have a Dapper or Feisty release of Ubuntu, or something similar. This isn’t an involved project, it’s just hard to find a basic installation technique in one place. It’s hoped for this to be your starting point with SNMP, not an ending point.
Installing the software
root@ibsen:~# sudo apt-get install snmpd Reading package lists... Done Building dependency tree Reading state information...

answer y
2. Configuration
backup existing /etc/snmp/snmpd.conf configuration file to /etc/snmp/snmpd.conf.org
cp /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.org
Create a new /etc/snmp/snmpd.conf file:
rocommunity public syslocation "Gedung Analisis, Datacentre- UPT Puskom" syscontact septa@polinela.ac.id
Uncheck comment
agentAddress udp:161,udp6:[::1]:161
Make snmpd use the newly created file and make it listen to all interfaces:
Edit /etc/default/snmpd
Change from:
# snmpd options (use syslog, close stdin/out/err). SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1'
To:
# snmpd options (use syslog, close stdin/out/err). #SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1' SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid -c /etc/snmp/snmpd.conf'
and restart snmpd
/etc/init.d/snmpd restart
3. Test
Do a snmpwalk from another host against your newly configured host.
[root@op5 ~] snmpwalk -c public -v1 192.168.1.12 | less SNMPv2-MIB::sysDescr.0 = STRING: Linux ibsen 2.6.27-9-generic #1 SMP Thu Nov 20 21:57:00 UTC 2008 i686 SNMPv2-MIB::sysObjectID.0 = OID: NET-SNMP-MIB::netSnmpAgentOIDs.10 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (68869) 0:11:28.69 SNMPv2-MIB::sysContact.0 = STRING: septa@polinela.ac.id SNMPv2-MIB::sysORLastChange.0 = Timeticks: (1) 0:00:00.01 SNMPv2-MIB::sysORID.1 = OID: SNMP-FRAMEWORK-MIB::snmpFrameworkMIBCompliance SNMPv2-MIB::sysORID.2 = OID: SNMP-MPD-MIB::snmpMPDCompliance SNMPv2-MIB::sysORID.3 = OID: SNMP-USER-BASED-SM-MIB::usmMIBCompliance SNMPv2-MIB::sysORID.4 = OID: SNMPv2-MIB::snmpMIB SNMPv2-MIB::sysORID.5 = OID: TCP-MIB::tcpMIB SNMPv2-MIB::sysORID.6 = OID: IP-MIB::ip
Yes it works!!

Webmin is a web-based interface based on Perl for system administration under Unix-based systems. With Webmin, you can easily set up, via your web browser, new user accounts, manage disk quotas, configure files, control the Apache server as well as MySQL and PHP. In this guide, we will see how to install Webmin on a server running Ubuntu 11.04 or 11.10.
Webmin Installation
Before we start, you should first install the LAMP web server on your system. Now follow these instructions to install Webmin on Ubuntu 11.10/11.04:
1. Open the Terminal and run this command:
sudo gedit /etc/apt/sources.list
At the end of the file, add these two lines, then save and close:
deb http://download.webmin.com/download/repository sarge contrib
deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib
2. Import now the GPG key using these commands:
wget http://www.webmin.com/jcameron-key.asc
sudo apt-key add jcameron-key.asc
sudo apt-get update
3. Install now Webmin with this command:
sudo apt-get install webmin
Accessing Webmin
To start Webmin, open this address using your web browser:
To login to webmin, you need to use your root account details. If you still haven’t assigned a password to your root account, then create a root password using this command via the terminal:
sudo passwd
Enter a new password, then resubmit it to confirm. Then use your root account access details to login to webmin.

ente admin ,trus lupa password root nya??tested on ubuntu server ,..keturunan debian,..jadi di debian sama aja kali ya
1.booting server dg mengunakan live cd
2.masuk console dan buatlah folder dg cara
mkdir mnt/septa
3.ketik fdisk -l ( untuk melihat disk yg akan di mount ), pergunakan feeling anda mana partisi linux anda yang menjadi /root sebelumnya
4. ketik: mount /dev/hda1 /mnt/septa tekan enter
5. chroot /mnt/septa tekan enter
6. ketik: passwd root enter lalu masukan password yg baru.
beresssss
