It is just that when something gets labeled deprecated often there is a note indicating that put in the man page, but I didn't see one for nslookup. ISC announced the deprecation of nslookup(1) as part of the major rewrite before the release of Bind9. If you install the Bind9 port you will find that there isn't a nslookup(1) man page any more. Also, running nslookup(1) emits the following message: % /usr/local/bin/nslookup Note: nslookup is deprecated and may be removed from future releases. Consider using the `dig' or `host' programs instead. Run nslookup with the `-sil[ent]' option to prevent this message from appearing. and the BIND9 documentation includes this statement: Due to its arcane user interface and frequently inconsistent behavior, we do not recommend the use of nslookup. Use dig instead. These notices will no doubt appear in the base system when BIND 9 is imported. Currently FreeBSD ships with BIND 8.3.7: what the plans are for importing Bind 9 I do not know.

Ah, a couple of our group has looked at Bind 9 , but so far we have not moved to it. So, guess I wouldn't see an message, even in the on the servers with 4.9 FreeBSD I just installed this week.

Morning everyone. I'm having a major brain freeze this morning. I dont recall how to find the reverse for an IP address? I need to do some testing with a few IP addresses, to ensure they have valid reverse's set, but dont recall how to check them. If I remember, you could do it with both 'nslookup' and 'dig' correct? Sure. just nslookup xxx.xxx.xxx.xxx and if it comes back with a good/authoritive hostname it should be OK. Try man nslookup for more possibilities. jerry Anyone have a moment to help me out here? In the meantime, it's man page time... I appreciate the help.

Hi! deprecated means, that this program has a successor (in this case dig(1) ) and it may happen, that it disappears in a future release. So you get that warning, so that you have time to get familiar with it, that you may re-write some of your scripts still using nslookup etc. HTH Olaf -- Olaf Hoyer[EMAIL PROTECTED] Fuerchterliche Erlebniss geben zu raten, ob der, welcher sie erlebt, nicht etwas Fuerchterliches ist.
