hi

I have a red hat enterprise server and i'm running apache on it. This machine has an internal ip which is 192.168.1.5. I have another server on which i have configured the subdomain which is test@m.co.in which is pointing to an external ip address. The external ip address is configured on the firewall and any requests to that ip is routed to the internal ip of that server.

when i host the site in this machine, i am able to access this site with the subdomain from outside our office, but not able to use the same domain name to access within the office. within the office i can use only the internal ip address.

can someone tell me how to configure the subdomain so that i can access the website both internally and externally using the same sub domain name..

thanks

Hi,

It looks like your DNS is not working locally. You can try the following:

1) Put this line at /etc/resolv.conf
domain your_subdomain

2) Put this line in /etc/hosts
server_ip_address servername.your_subdomain servername

3) The line for hosts in /etc/nsswitch.conf should look like this
hosts: files dns

You should do this for every client on the local network. Another possible solution would be to configure your own DNS server.

Hi Igor,

Tried what you said, but not going through. Could you tell me the alternative?

Hi Igor,

Im able to ping the subdomain name and it goes to the internal ip server. but when i type the address in the browser, it doesnt go through

Hi,

Could you please send those 3 files I mentioned above and the error you get from the browser?
Also try modifying the line in /etc/resolv.conf like this:

server_ip_address your_subdomain servername

With the previous setting it should work if you type http://servername.test@m.co.in/ in your browser.

here are the files contents

nsswitch
# /etc/nsswitch.conf
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Legal entries are:
#
# nisplus or nis+ Use NIS+ (NIS version 3)
# nis or yp Use NIS (NIS version 2), also called YP
# dns Use DNS (Domain Name Service)
# files Use the local files
# db Use the local database (.db) files
# compat Use NIS on compat mode
# hesiod Use Hesiod for user lookups
# [NOTFOUND=return] Stop searching if not found so far
#

# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd: db files nisplus nis
#shadow: db files nisplus nis
#group: db files nisplus nis

passwd: files
shadow: files
group: files

#hosts: db files nisplus nis dns
hosts: files dns
# Example - obey only what nisplus tells us...
#services: nisplus [NOTFOUND=return] files
#networks: nisplus [NOTFOUND=return] files
#protocols: nisplus [NOTFOUND=return] files
#rpc: nisplus [NOTFOUND=return] files
#ethers: nisplus [NOTFOUND=return] files
#netmasks: nisplus [NOTFOUND=return] files

bootparams: nisplus [NOTFOUND=return] files

ethers: files
netmasks: files
networks: files
protocols: files
rpc: files
services: files

netgroup: files

publickey: nisplus

automount: files
aliases: files nisplus

Hi,

You have to properly configure the DNS server you are running on 192.168.1.4. There is a DNS tutorial in the Tutorials section on this page so you can look at it or google for some other.
Sorry I couldn't help you more.

thanks igor.. i have managed to do it at the firewall itself.. thanks
