im kinda stuck using this $dnsip = gethostbyname($feature_name); works for full dns name but fails on for example nagios on the same machine though i have the search paths added horizon:/var/www/ops-ssl/datacentre# more /etc/resolv.conf search search its.manchester.ac.uk mcc.ac.uk mc.man.ac.uk fin.manchester.ac.uk sdt.manchester.ac.uk ds.man.ac.uk nameserver use domain.200.6 nameserver use domain.203.17 nameserver use domain.203.7 nameserver use domain.200.2 so horizon:/var/www/ops-ssl/datacentre# nslookup nagios Server: use domain.200.6 Address: use domain.200.6#53 Name: nagios.its.manchester.ac.uk Address: use domain.249.4 returns the correct IP why dose it fail in php ? |

I remember trying this and never getting it working, but i didn't really try to solve the issue. Take it you've looked through the comments at http://us2.php.net/manual/en/function.gethostbyname.php Those are usually the best place to start with tracking down issues in php functions, as often folks find a solution years before you have a problem

Maybe it would be because the manual says that it should be a fully qualified domain name, whereas your local DNS client will search your local network. Maybe a good solution would be to detect if the submitted variable has a '.' in it and if it dosent then to append the local networks on to the end and surch through them in turn. |

cheers - unfortuanly we have around 100 diff dns domains/sub domains to check but i never thought of doing this <?php $ip = rtrim(`/usr/bin/dig $host A +short`); ?> it will solve 80% of me problems untill i hit and example like a machine slappy slappy.mc.man.ac.uk see slap slappy.its.manchester.ac.uk slappy.umist.ac.uk etc etc all diff machines - this is just a example but i know loads that will do this |
