Hi,
We have moved our DNS server from one IP to another. But on a Linux
server, the PHP programs keep using the old DNS server IP. For
example, for a simple php file:
<? echo gethostbyname ("smtp.cpttm"); ?>
When it is run, it tries to lookup smtp.cpttm using the old DNS
server (I know it using tcpdump). The new DNS server is specified in
/etc/resolv.conf. If I issue "ping smtp.cpttm" in a command prompt,
then tcpdump shows that it is accessing the new DNS server.
Any idea? Thanks.
