Hey Guys,

I thought it might be nice if we all shared the tools we use to troubleshoot day to day technical problems.

I know a lot of HostMySite technicians have personal sites designed for this very purpose, so please list your sites here, and if we see enough interest I'll make this post Sticky.

Email Tools
* SMTP Server Test
* SMTP Authentication Test
* Mail User Agent Test
* Email Header Analyzer

DNS Tools
* DNS Lookup
* Reverse DNS Lookup

Domain Tools
* Whois lookup
* IP Whois lookup

Miscellaneous
* HTTP Test Tool
* Base64 Converter
* HTML to Plaintext Converter

I haven't really made any tools, b/c they already exist on the internet, and I hate duplication of effort. However, some valuable contributions are below:

temp URLs, I'll update them someday.

I've got a MySQL collation script put together from other samples. It pulls a list of all tables/columns and generates the scripts to change the charset/collation based on your choosing.

Warning: Theres no SSL right now and no plans to add one. Your password is sent in plain text to the server then unset. The script is harmless and simply generates queries, I included the source as well.

BetterWhoIs: http://www.betterwhois.com
As the name implies, it gets the WhoIs information for standard domain names (.net, .com, .org, etc)

Test An Email Address: http://www.hq42.net/net_tools/test_email_addr.php
Tests the format and functionality of an email address by making a real time SMTP connection and attempting to deliver to the email you provide. Note that it closes the connection before delivering the body, so no email is actually sent. Also doesn't work on some major providers (i.e. hotmail, yahoo, gmail, etc). Oh, and you can't use it more than 10 times in a day from a single IP.

MySQL Performance Tuning Tools * Keep in mind these tools are useful for any system performance analysis you might need as well! These are specific to *nix type Operating Systems.
