RSA Version/Condition: 6.9.1, 7.0.0
Platform (Other): Soft-appliance
O/S Version: Red Hat Enterprise Linux 6.x
 
IssueAn error, as shown in the terminal output snippet below, is seen during execution of install.sh on software appliance, using  RedHat Linux 6.x OS.
# cd /tmp/aveksa/staging
# ./install.sh
.

.
Checking /etc/hosts file entry...
common.sh: line 508: gethostip: command not found 
gethostip -d <domainname> does not match hostname -i
Make sure <domain-name> is set to <ip-address> in your etc/hosts
#
CauseThe reason gethostip is not found is either because it's default location of /usr/bin is not in the (root) users PATH environment variable definition or because the command does not exist on the system because the OS package (syslinux) that contains this command is not installed on this environment.

The second error  'gethostip -d' output does not match 'hostname -i'  output, is not because the hostname is not correct in /etc/hosts.  In this specific case, this error is a result of no information being returned by the gethostip command - which of course does not match the information that IS returned by the hostname command.


 
ResolutionThis problem only occurs on software appliances where the Customer needs to build out the OS.  Not all packages are installed by default.  The most common reason for this error is #1 shown below -  the syslinux package has not been installed.
  • If gethostip does NOT exist in /usr/bin, then check to see if the OS package that contains is (syslinux) has been installed.
  • If gethostip does exist in /usr/bin, and /usr/bin is not in $PATH, then add /usr/bin  to the PATH environment variable.
  
The examples below show when the gethostip command is found, is in $PATH and has been installed as part of the syslinux package.
If either of these commands return no information, then corrective action must be taken.


1. Check to see if the OS package that contains is (syslinux) has been installed.
# rpm -qf /usr/bin/gethostip
syslinux-4.02-7.2.el5

If it has not been installed, then the syslinux package must be installed, using a tool such as rpm or yum.  The version of syslinux should be appropriate for the version of RedHat that has been installed.   Appropriate commands would include the following:
 
yum install -y syslinux

 


OR


rpm -Uvh <RH OS media location>/syslinux*


2.  Check to see if the file exists in /usr/bin, and if /usr/bin is in the $PATH environment variable.  
# ls -l  /usr/bin/gethostip
-rwxr-xr-x 1 root root 8728 Oct 15  2012 /usr/bin/gethostip

# echo $PATH

.:/u01/app/oracle/product/12.1.0/db_1/bin::/etc/alternatives/java_sdk_1.7.0/bin:/usr/kerberos/sbin:/usr/kerberos/bin:/opt/ant/ant/bin:/usr/bin:/bin:/sbin:/usr/sbin:/mnt/sysimage/bin:/mnt/sysimage/usr/bin:/mnt/sysimage/usr/sbin:/mnt/sysimage/sbin:/mnt/sysimage/usr/X11R6/bin:/root/bin

If /usr/bin is not in the PATH environment variable, it can be added by running a command similar to this:
# export PATH = $PATH:/usr/bin
