The script :
-------------------
$nom="mail";
$adr=gethostbyname($nom);
echo "$nom=$adr<BR />";
$fp=fsockopen ($adr, 110, $errno, $errstr, 30);
if (!$fp) {
    echo "$errstr ($errno)<br>\n";
} else {
    echo fgets ($fp,128) . "<BR />\n";
    fputs ($fp, "QUIT\r\n");
    echo fgets ($fp,128) . "<BR />\n";
    fclose ($fp);

No probleme with PHP 4.2.3 on the same server.

(PHP 4.2.3 is include in HP WebServer Suite,
distributed by HP, in binary format)

I've downloaded php4-STABLE-200302201630

Compil/install Ok (on another port)

Same error.

After some search, i've found that the "getaddrinfo" function doesn't work under HP-UX 11.11 (ok for host
in the host file, ko for dns).

I apply 3 patch :
  PHCO_27740 libc cumulative patch
  PHCO_24402 libc cumulative header file patch
  PHNE_27796 libnss_dns DNS backend patch

And now the script works fine.

I give the info for the other HP-UX and PHP users.
I think you can close the bug.

Cordialy.

Not a bug in PHP, so marking as bogus.

Thanks for looking into this; we don't really have
any HP-UX resources ourselves.
