I have modified a script to do a circular DNS look up.
The theory is this
for a given subnet build a range if IP's
do a reverse look up on those IP's
take the output of the reverse look up then and do a forward look up
If the returns match up give a good status
If not return a fail status.
It runs really nice except when it runs into multi-homed IP's.
I am now trying to script in to check if the reverse lookup returns more than one entry, and if so then do a look up on any returns.
I might know the answer to this, but I just want to see if any of you know any work arounds before I go and re-write the whole thing.
I have a script as follow:
$ cat testing
#! /usr/bin/ksh
f ()
{
echo "Type \"y\" \c"
read value
if ;

I have tried thought of using instfix -ivqc | grep BIND , but this did not return the result I was looking for; it seem to list out the the different patches that had been applied to BIND. I'm actually looking for overall version, like you'd get when checking the OS level for instance. (1 Reply)

1. The each line in 'MyFile' has 7 columns, and that the values in the 5th column are integers. I need to use shell functions (and standard LINUX/UNIX filters) to... (1 Reply)
Hello Experts,
I have a script that that transfers a file (via sftp) and it works fine but we ran into a snag where the target server asked for the ssh key and the script didn't know what to do. I want to add some logic to this script that at least sends an email that it didn't complete as... (4 Replies)
Hi Experts,
I have lot of Solaris servers and in most of them, root disk is mirrored in rootdg. I just want to check all servers, if there is any server whose root disk is not mirrored. Either it may be with detached plexes or not mirrored at all. I can run a for loop for all servers. Can... (4 Replies)
