Re: localhost vs. 127.0.0.1 error: 'Lost connection to MySQL server during query'
Hello. [EMAIL PROTECTED]:~# telnet localhost 43306 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Connection closed by foreign host. I had an experience with similar symptoms which was caused by TCP wrapper. Check your /etc/hosts.allow. Lance Rochelle wrote: OK here goes I've had a problem for a few days that I can't resolve. At the OS level If I ping the name localhost I get a good return and if I ping 127.0.0.1 I also get a good return as noted below.
