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. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
