Generate list of all HPUX servers

[Rpger Tavener]

How can I generate a list of all the HPUX servers. I would like to route the output to a file.

Thanks

roger,

I would expect that you might already have a list in /etc/hosts. If you have other servers listed in there, you can edit it to put in comments that identify the type of server like this:

130.1.0.249 dam dam.holstein.com #unixhost#dam


Other than that, I can't think of a way to find this information from the command line.

It seems to be impossible one.

Just to add something:

I can get list of IP address rather than names of all hosts in the network. And that is possible by doing ==>

#ping > /tmp/hostsIP

You might be able to use something like snmpwalk

How about using expect for this?

Telnet to box, if you get hp-ux string, it is hp-ux server else not.
(But this is not a very reliable way and you can always change the stuff that is displayed during login)

Hope this helps.

First of all, why do you want to do this?

Secondly, presumably you mean all the
HP-UX servers on your LAN or in your
domain, not the entire Internet!

The tricky part is figuring out what hosts
you want to query. /etc/hosts might
have such a list, but if you're using
NIS or DNS you'll have to use something
like nslookup to get the list. Try the
"ls" command inside of nslookup. ("ls -h"
supposedly lists the CPU and OS info
records for all machines in a domain, but
that info is not always reliable.)

Once you have the list of servers you're
interested in, try using telnet (in a
script) and check the banner, e.g.:

HP-UX hpux_box B.11.22 U ia64 (tc)

Hey Roger,
Anil touched on the very thought I had. I know of no other method to obtain this information than using telnet to obtain the
initial system message, i.e.:

HP-UX rufus 11.00 U 9000/800 (ta)

This is actual output of a test (rufus is the hostname) and you can not only tell the OS type (HP-UX), but the version (11.00). However, as Anil mentioned, this is not always reliable as the message can be changed or removed and you can be returned nothing or a fake string (an SA can make the system report that it's a MAC OS or some other OS).

Also, some telnet sessions do not automatically timeout so it would be hard to generate a script that can obtain this info, dump it into a file, and then break out '^]' of the telnet session and continue.

If you trust that nobody has changed the system string on the systems that you are trying to obtain this information from then this is a valid option and won't take a lot of time. Also, if you are not good at writing scripts but you have a GUI screen, you can simply cut and paste the hostname/IP you are performing the telnet to and the system string you receive.

Hope this helps. Good luck!
