How Do I Check Whether Host Names in the SUSE Linux System Files Are the Same

Question

If the server host name is modified incompletely before Database is installed, the host names in the SUSE Linux system files will be different.

How do I check whether the host names in the SUSE Linux system files are the same?

Answer

1. Log in to the SUSE Linux server and run the following command to view the host name in the system file.

   # uname -a

   Information similar to the following is displayed:

   Linux eSightServer 3.0.101-0.47.99-default #1 SMP 2010-05-20 11:14:20 +0200 x86_64 x86_64 x86_64 GNU/Linux

   The host name is eSightServer.

2. Run the following command to view the host name in the system file.

   # more /etc/hosts

   Information similar to the following is displayed:

   # 
   # hosts         This file describes a number of hostname-to-address 
   #               mappings for the TCP/IP subsystem.  It is mostly 
   #               used at boot time, when no name servers are running. 
   #               On small systems, this file can be used instead of a 
   #               "named" name server. 
   # Syntax: 
   #     
   # IP-Address  Full-Qualified-Hostname  Short-Hostname 
   # 
    
   127.0.0.1       localhost  
    
   # special IPv6 addresses 
   ::1             localhost ipv6-localhost ipv6-loopback 
    
   fc00::0         ipv6-localnet  
    
   fc01::0         ipv6-mcastprefix  
   fc02::1         ipv6-allnodes  
   fc02::2         ipv6-allrouters  
   fc02::3         ipv6-allhosts  
   10.137.59.36    eSightServer eSightServer     

   The host name is eSightServer.

3. Check whether the two host names are the same. If they are different, contact SUSE Linux system administrator.
