whois myname.com
The computer will check the NIC database. If there is no reply they you need to apply to get the name registered. If the name comes up registered to someone else, you are out of luck. You are going to have to choose another name.
nslookup myname.com
The computer will come back and tell you the IP adress of that name.
If you do not get an ip address back, then you need to do name server configuration. If you get back the wrong address, it may take several days to undo the damage because the server caches the names. Try to make sure you do it right the first time as this will save huge headaches.
Two DNS setups are included with T1 or server colocation at Brand X. For those those two just let us know what you want and we will help at no charge. After that it's $50 per name, or you can set up your own name server.
Telnet to the server that is going to do DNS. Login and do the "su" command with the password to become superuser. Now change directory to /etc (cd /etc) and list the files using the ls command. You should see the file named.boot. Look inside it using the pico program. You are going to have to make some additions here. Look at the section down below. Follow the model to add a line to refer to the domain you want to add. Basically you are going to type "pico named.boot" to open the file and then add a line that looks like:
primary axium.com axium.db.Try and leave things looking neat; a comment or two and neat columns will be a nice touch.
When you are done type ^o to save the file and type ^x to exit the pico program.
This will change the file. Now we need to create a .db file. You should copy one that already works and then change the names in it. I'm going to make three of them today. Type:
cp /etc/namedb/marketingnet.db /etc/namedb/cybrport.com cp /etc/namedb/marketingnet.db /etc/namedb/axium.com cp /etc/namedb/marketingnet.db /etc/namedb/comspan.com
Fine. Now lets have a look.
Change directories by typing "cd /etc/namedb" and then list the files using the ls command. You should find your new files. Edit them. Here's what one of the files looked like before I edited it:
@ IN SOA brandx.net. hostmaster.brandx.net. ( 9510031 ; Serial number 172800 ; Refresh every 2 days 3600 ; Retry every hour 1728000 ; Expire every 20 days 86400 ) ; Minimum 1 day IN NS ns1.brandx.net. IN NS ns2.brandx.net. IN MX 10 brandx.net. IN A 204.140.224.2 ; ; Local loopback host localhost IN A 127.0.0.1 ; ; Canonical Names www IN CNAME marketingnet.com. ftp IN CNAME marketingnet.com.
Edit the above file and you get
@ IN SOA brandx.net. hostmaster.brandx.net. ( 9511221 ; Serial number 172800 ; Refresh every 2 days 3600 ; Retry every hour 1728000 ; Expire every 20 days 86400 ) ; Minimum 1 day IN NS ns1.brandx.net. IN NS ns2.brandx.net. IN MX 10 brandx.net. IN A 204.140.224.5 ; ; Local loopback host localhost IN A 127.0.0.1 ; ; Canonical Names www IN CNAME cybrport.com. ftp IN CNAME cybrport.com.
(I just switched marketingnet to cybrport, and changed the address to 204.140.224.5 Also, you *must* change the serial number to reflect the new date. 95 is the year. 11 is the month. 22 is the date. 1 means this is the first edition of the day. Updating this serial number is necessary or the name server update will not propogate to other system. Dumb system, but that's what you ahve to do to make it work.)
Now we need to restart the name server. You can do this by rebooting the computer, but there are easier (faster ways) Find the process number:
Brand X % ps -ax | grep named 7982 ?? Ss 8:09.55 /usr/sbin/named 28033 p0 S+ 0:00.03 grep named
OK, the process number is 7982 (you may get a different answer). Now we restart the name server:
Brand X % kill -1 7982
The next step is to verify that the computer knows where to find your domains
Brand X % nslookup comspan.com Server: brandx.net Address: 198.147.97.1 Name: comspan.com Address: 204.140.224.7
This looks right, it's the address I wanted. Our address is set up. Next, we're going to do some mail server configuration. It's pretty easy. Note that it is very important to get the right address.
You have the name working (I hope). Open the mail config file by typing "pico /etc/sendmail.cw" and then add your domain to the bottom of the list. Very easy. So easy it's not even worth taking the space to show you what this file looks like.
Look in the directory /etc/sysconfig/network-scripts. You will find some files with names like:
[root@echavez network-scripts]# ls ifcfg-eth0 ifdown-post ifup ifup-plip ifup-routes ifcfg-lo ifdown-ppp ifup-aliases ifup-post ifup-sl ifdown ifdown-sl ifup-ipx ifup-ppp network-functions [root@echavez network-scripts]#Here's the contents of the file ifcfg-eth0 (which sets the base IP address of this server:
[root@echavez network-scripts]# cat ifcfg-eth0 DEVICE=eth0 BOOTPROTO=static IPADDR=209.55.67.37 NETMASK=255.255.255.0 ONBOOT=yes [root@echavez network-scripts]#We are going to take the file ifcfg-eth0 and make a copy which we will call ifcfg-eth0:0.
[root@echavez network-scripts]# cp ifcfg-eth0 ifcfg-eth0:0Now edit the new file using pico. Once we are done it should look like this:
DEVICE=eth0:0 BOOTPROTO=static IPADDR=209.55.67.72 NETMASK=255.255.255.0 ONBOOT=yesNote that we have changed in two places: line1 (eth0:0) and line 2 (the new address.) At Brand X we have a web page where we keep track of all the assigned IP addresses. If you have a server you will be assigned some addresses and it will be up to you to keep track.
When you restart the server it will have the new address added. You can verify this by using the ifconfig command.
[root@echavez network-scripts]# /sbin/ifconfig eth0 Link encap:Ethernet HWaddr 00:60:08:3B:63:9E inet addr:209.55.67.37 Bcast:209.55.67.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:20386952 errors:0 dropped:0 overruns:0 frame:0 TX packets:35577 errors:0 dropped:0 overruns:0 carrier:0 collisions:25 txqueuelen:100 Interrupt:10 Base address:0xc000 eth0:0 Link encap:Ethernet HWaddr 00:60:08:3B:63:9E inet addr:209.55.67.72 Bcast:209.55.67.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:10 Base address:0xc000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:3924 Metric:1 RX packets:20 errors:0 dropped:0 overruns:0 frame:0 TX packets:20 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 [root@echavez network-scripts]#You can create more files, one for each new ip address, with names that end in eth0:0,eth0:1, etc.
Change the domain name to the nw domain name of the virtual host you are creating.
Change the option labelled "documentroot" to the name of the directory that this virtual host should go to.
Here's an example of the addition made to this file to support one virtual host, for marketingnet.com:
Sample:
#Make it look like this:#ServerAdmin webmaster@host.some_domain.com #DocumentRoot /www/docs/host.some_domain.com #ServerName host.some_domain.com #ErrorLog logs/host.some_domain.com-error_log #TransferLog logs/host.some_domain.com-access_log #
NameVirtualHost 209.55.67.37ServerAdmin callerconnect@theworld.net DocumentRoot /home/http/www/callerconnect ServerName www.callerconnect.com ErrorLog /home/callerconnect/logs/error.log TransferLog /home/callerconnect/logs/access.log
You will probably need to restart the server to make this work.
Find out the process number of the httpd process:
cellini % ps -ax | grep httpd 213 ?? Ss 2:15.40 /usr/contrib/bin/httpd 4918 ?? I 0:01.62 /usr/contrib/bin/httpd 5000 ?? I 0:01.28 /usr/contrib/bin/httpd 5654 ?? I 0:00.29 /usr/contrib/bin/httpd 5674 ?? I 0:00.50 /usr/contrib/bin/httpdI actually got about fifty lines when I tried this, but the first one is the one we are interested in. The Process ID (PID) is 213. Now use this information to restart the process, by typing "kill -1 PID", where PID is the PID number we just found.
