How do I start hpux network service?

Use following command to start HP-UX network service:

/etc/init.d/net start
/sbin/init.d/net start
Please note that your network configuration file is /etc/rc.config.d/netconf . Here is my sample /etc/rc.config.d/netconf file:

# cat /etc/rc.config.d/netconf
HOSTNAME=deephpux < --change hostname here OPERATING_SYSTEM=HP-UX LOOPBACK_ADDRESS= INTERFACE_NAME[0]=lan0 IP_ADDRESS[0]= <--change IP address here SUBNET_MASK[0]= <--change subnet mask here BROADCAST_ADDRESS[0]="" DHCP_ENABLE[0]="0" <--Do you wanna DHCP? set 1 to use DHCP

You can also set IP address using ifconfig command:
# ifconfig lan0 netmask up

See or get current IP address information with ifconfig command:
# ifconfig lan0

For more information see the summery of HP-UX networking related tools and commands.

Removing Unwanted Startup Debian Files or Services

Under Debian Linux ( and most other distros) startup files are stored in /etc/init.d/ directory and symbolic linked between /etc/rcX.d/ directory exists. Debian Linux (Red Hat/ Fedora) uses System V initialization scripts to start services at boot time from /etc/rcX.d/ directory. Debian Linux comes with different utilities to remove unwanted startup file:

(A) rcconf
It is a console based interactive utility that allows you to control which services are started when the system boots up or reboots. It displays a menu of all the services which could be started at boot. The ones that are configured to do so are marked and you can toggle individual services on and off. To start rconf, login as root user and type rcconf
# rcconf

Debian rcconf – a console based utility to control startup services

Select the service you would like to enable or disable.

(B) sysv-rc-conf is yet another tool for for SysV like init script links under Debian Linux. To start sysv-rc-conf, login as root user and type sysv-rc-conf:
# sysv-rc-conf

Debian sysv-rc-conf – a console based advanced utility to control startup services

Select the service you would like to enable or disable.

Both sysv-rc-conf and rcconf are best tools to use on Remote Debian Linux or when GUI is not available, they are just like ntsysv command under Red Hat Linux.

(C) You can also use update-rc.d script as follows (update-rc.d removes any links in the /etc/rcX.d directories to the script /etc/init.d/service):
# update-rc.d -f {SERVICE-NAME} remove

For example to stop xinetd service at boot time, type the command as follows:
# update-rc.d -f xinetd remove

Yahoo enhanced my hosting services again!

Last time they upgraded my account from 100 MB to 4 GB and today they have enhanced it again to 10 GB and what’s more data transfer has also increased to 400 GB. Almost everything in my plan has expanded — except the price. To be frank 2 days before, I had some issues with MySQL at that time I got some hint from tech support that they are enhancing disk space for all plans :).

Why I had selected Yahoo Webhosting?

  • Multiple IP address so that site runs 24×7 and it can take load. In control panel they have an option that allows to site grow on fly if sites get too many hits. You can also true off this feature.
  • Uses Akamai to serve contains for ftp and www, so if i created and used from it reduced load and my sites works very fastly
  • Separate/dedicated MySQL server avoids mysql/webserver disk hog problem
  • They backup the entire site and creates multiple snapshots so that I can restore site or single file from control panel. I don’t have to worry about backup problems
  • Unlimited MySQL database; you can creates as many as Mysql database you want.
  • Includes free $50 Google Adwords and other discounts on Marketing Services
  • Other features are listed here

So far my experience with them is the one of the best service with multiple IP address just type nslookup and you will know what I’m talking about.
[code]$ nslookup

Non-authoritative answer: canonical name =
They provide the same infrastructure that used by It means I’m using Akamai services for my hosting :)
As far as control panel is concern it is also one the best with in build file manger that can create files, upload files and other management.

But one question remained unanswered? Why the hell they enhanced it? My guess is Googles Ghosting/webhosting could be one of the main causes (it is not started yet). But google do have a plan to enter in this business (see Google becomes domain name seller) if I consider domain growth and Why Google Will Defeat Yahoo! in the Web Hosting War. Remember what Gmail did to yahoo and other email services. Before Google starts to offer massive hosting account Yahoo upgraded service and reduced prices. Good move, IMPO.

/etc/resolve.conf or resolv.conf File Example

The resolv.conf file is the resolver configuration file. It is use to configure client side access to the Internet Domain Name System (DNS). This file defines which name servers to use.

The resolver is a set of routines in the C library that provide access to the Internet Domain Name System (DNS). The resolver configuration file contains information that is read by the resolver routines the first time they are invoked by a process. The file is designed to be human readable and contains a list of keywords with values that provide various types of resolver information

Note: File name is /etc/resolv.conf and not /etc/resolve.conf.

Sample resolv.conf file

Following is an example of resolv.conf file:



  • search The search list is normally determined from the local domain name; by default, it contains only the local domain name. So when you type nslookup www, it will be matched to
  • nameserver Name-server-IP-address: Point out to your your own nameserver or to ISP’s name server. Up to 3 name servers may be listed.

But how do I edit the /etc/resolv.conf file?

Use text editor such as vi or gedit from Linux desktop:
# vi /etc/resolv.conf

Default /etc/resolv.conf file

Following file should be work with any ISP in the world :)
# cat /etc/resolv.conf

Linux Testing your network connection

1) First try pining your own IP address to see if your IP address is set properly, syntax is:

If your IP address is then try:
# ping

Tip use ifconfig command to see IP address for eth0 or any other interface.

2) Try pinging neighboring machines IP addresses:
# ping
# ping

If you need to setup/configure network or connecting to the network under Linux use following tools:
Under Red Hat use neat OR system-config-network (Fedora core) command
Uder Debian Linux use network-admin command.

You can also start above command from GUI. Using above GUI tools you should able to configure DNS, hosts, IP address etc. For more information see:
