getting alias name 1

[hok1man]

hi guys,

just wondering how to get alias name from the real hostname :
I usually use nslookup, but it just works if I do like this:

nslookup [aliasname]

yes, it will give me the alias name and the real name, but if I use the realname

nslookup [realname]

it won't give me the alias name, any idea how to get alias name guys?

Thanks,

I think you have to ( on AIX ) set query to type=A or type=CNAME to force one or the other.

Is that what you are after?

Hi dwcasey,

where to set the query type?
I am after the unix command or solution...

Thanks,

nslookup accepts multiple commands when run interactively (i.e. without parameters). I think that's where you set the query type; check the man page.

Also, consider trying the host command if it's available on your OS.

nslookup -query=cname server01

nslookup -query=a server01

You want the alias that points to the name. I don't believe this is possible, the cname searches look for the alias, not the target. So in other words, you need to already KNOW the alias before you ask for it! There is no user command that will back track aliases that point to a host. The reason? A cname can be used to point at a host from ANY domain, so you would have to search ALL internet dns records to get a comprehensive list (or change how the protocol works so that cnames are registered!, fat chance).
