NSLOOKUP for 98 SE

27 posts in this topic

Nslookup is a command-line DNS lookup, normally only available on Windows NT and above and Unix. I found a freeware replacement; you can download it here:

http://www.pc-help.org/trace/trace.zip

There are some other network tools in this file such as whois.exe; I am not sure what they all do. Anyway, I suggest putting NSLOOKUP.EXE in your C:\WINDOWS directory. This should be in USP2.1 :)

FWIW, I am using nslookup.exe right now to check through all 110,000+ entries in my HOSTS file (3.6 MB) to look for dead hosts. I am using my normal DNS server that is chosen automatically through my dial-up connection. Does this sound like a good idea? Should I use multiple DNS servers? I am not really sure how DNS works.

If u want to cleanup, sort + alphabetize the HOSTS file [i presume it's the 1 I sent u a while back] and remove dead servers, d/l this ZIP [145 KB]:

http://www.mdgx.com/files/HFT.ZIP

Contains everything u need for this purpose. ;)

Enjoy.

BTW: When you're done cleaning your HOSTS file, can u send me a copy, please?

Will do, but it may be a while.. CIP seems perfect and extremely fast but it unfortunately drains an enormous amount of system resources, usually causing an OS crash within seconds. This program was written in 1998 and I don't understand what the programmers were thinking. The crashes occur even with small files (~5000 hosts). I gave up on CIP after rebooting the fifth time. :(

nslookup.exe -type=A does its job fine but is slow (sometimes it hangs for a while waiting for a response from the DNS server). I'm using system() to call it from a C++ program. it will take over 100 hours (longer in real life) to do 110,000 hosts (note: sorted and deduped). Maybe I'll have it do 100 nslookups in seperate threads - I guess basically that is what CIP is doing.

I downloaded a newer version of CIP - 5.0 SR6 I believe.

It doesn't have the resource-draining OS-crashing bugs, but it doesn't appear to work either. After about 1000 hosts it kinda gives up and trying to Stop or close the program won't work.

I located an even newer version and I'll try it out later...

What I did to make CIP work:

I've cut+pasted small fragments from HOSTS into CIP, and that way it didn't crash, but just like u said, it takes forever to check all those servers. :(

That's why I've abandoned this altogether.

With such a huge HOSTS [> 61000 servers], it won't matter if 100-200 are removed or not, the browser will take the same time to load the entire servers list anyway, so it's probably not worth checking.

Can u post the link to the newer CIP version, please?

Thanks.

Hmm, just a question, but could AM deadlink be used[ala cut/paste] ? or is CIP a better prgm for this, have a nother older puter that am setting up barebones with 98se + USP only that could possibly be used for this while sleeping, am on dialup so obviously would take many nites of peaceful slumber :D

Sure, here is the CIP 5.00 SR6 (the non-crashing version), it is about 185 KB:

http://files.webattack.com/localdl834/CIP500.exe

If you search for CIP 5.00 SR7 you will find it but it is either 242 KB (cip500.exe) or 138 KB (cip500.zip), and it is much worse in my opinion and it crashes. It looks older actually. Try it here if you want:

http://sitelance.com/files/CIP500.exe

http://www.filelibrary.com:8080/cgi-bin/fr.../105/cip500.zip

That's why I've abandoned this altogether.

I still haven't given up yet. I wrote a C++ program to launch many threads each doing gethostbyname(), and my program is faster than CIP I think (100 hosts a second on dialup). I could complete 110,000 hosts in an hour easily.

Edit: I've checked all 119,279 hosts. After the first pass, 105,000 hosts were validated. On the second pass, 200 more hosts were verified. I'll keep checking until I am no longer able to find valid hosts.

Wow, great work.

And many thanks for the links.

If it's not much to ask and if it's not too big, could u send me your C++ program [zipped] in email?

E-mail

I'd like to try it. I am on cable [4 mbit/sec], so it should take only a few minutes [hopefully] to check all 61000 hosts.

Many thanks in advance.

And then I can send u a "clean" copy of the HOSTS. ;)

Sure, I'll send you everything tonight. If there is demand I will improve the program (it is awkward right now).

I have approximately 100,000 verified hosts now. I ran through my unverified hosts lists (13,000 hosts) a few times and it keeps verifying a dozen or so new ones each time. Probably this is affected by the DNS cache server I am using.

Azagahl, let me know if you decide to do anything w/your prgm, as I would be very interested in anything that fast on Dialup[all I can get in boonies]. Sounds like a surefire winner :thumbup

azagahl:

Guess what, I found the last official CIP500 version [unfortunately it's the crashing SR7 :(]:

http://www.radsoft.net/gallery/cip/CIP500.exe

Radsoft is the developer.

They don't distribute it anymore, because they went shareware, and CIP is now part of their "flagship" soft called Extreme Power Tools 2005.

Actually this is the same ver as the 1 u sent at:

http://sitelance.com/files/CIP500.exe

You're right, the best is SR6.

I've posted it SR6 here and also included it in HFT.ZIP:

http://www.mdgx.com/hosts.php

Thnx again.

Got the email. Thank you very much.

On my "tweaked" 98SE I couldn't make the exe run at all, it returns a memory address error. :(

I blame it on using UMBPCI mem manager. [?]

I'll let u know if I can make it work.

Wow... 3 MB [> 100000] worth of servers, that's quite an achievement.

And I thought I was the only 1 digging for HOSTS all over the net. :yes:
