Clickpack - Routine CPIPToDomain

[pnpmarques]

Hello,
I'm working with Clickpack to treat weblogs. I am trying to convert an IP adress to a domain using routine CPIPToDomain. The problem is that it doesn't do any conversion (Testing returns nothing, as well using it in a job).
I'll try to give you more information hoping that it helps you to help me:

There is no reference to it and I don't know much about its code but I believe that inside the routine, this line:
DScallPerl1("sub {my $ip = pack(N,$_[0]);$host = gethostbyaddr($ip,0); return $host; }","I",Key)
is calling the unix command nslookup.

If I execute the nslookup command like this:
/anydirectory/nslookup
I get:
bash: nslookup: command not found

I really have to put the whole path to get something:
/usr/sbin/nslookup 123.123.11.22
Name: name.company.pt
Address: 123.123.11.22

If I execute the nslookup command in a DS job (no path) a get this:
DSJobName..BeforeJob (ExecSH): Executed command: nslookup 123.123.11.22
*** Output from command was: ***
Server: name.company.pt
Address: 123.123.11.22

Do you think Clickpack is not well instaled or something is missing on the server configuration?
Thank You!

Hi Pedro,

It seems that the code snipet of the Clickpack CPIPToDomain routine you've posted has a wrong parameter regarding Solaris OS:

DScallPerl1("sub {my $ip = pack(N,$_[0]);$host = gethostbyaddr($ip,0); return $host; }","I",Key)

should be:

DScallPerl1("sub {my $ip = pack(N,$_[0]);$host = gethostbyaddr($ip,2); return $host; }","I",Key)

For some reason, the implementation of the gethostbyaddr(...) function only accepts the AF_INET protocol as 2, not 0. In Windows works both ways...who knows what will come next?

Cheers,
Henrique
