Re: Temporary failure in name resolution - fsockopen()

We recently para-virtualised a Xen / CentOS box which is running script which uses fsockopen() to get a connection to an SMTP server. Since the server changes it fails approx 50% of the time with: "php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution" We've tried the solutions from Googling this error (such as restarting Apache etc), but without success. Why am I wasting your time with a Linux upgrade issue? Well, gethostbyname() seems to resolve the IP every time. Manual lookups on from the server seem to work with no problems. Any help greatly appreciated. Should I perhaps be pointing this out on the 'internals' list?

I feel its something do with your DNS settings and/or the server. If that's not the problem then just as a temp solution add your SMTP server's address provided it has a static IP (99.9% it has) to your /etc/hosts file. It should not give trouble then. -- Nilesh Govindarajan Site & Server Administrator www.itech7.com
