SSH and FTP connect slow
Hi again guys,

Earlier today, just all of a sudden, all SSH and FTP connections to my internal Linux box just slowed down to a crawl. After the connection/authentication though, everything was back to normal speed. Until you have to connect again. A box reboot didnt work either.

Now, from previous experience, I immediately suspected reverse DNS lookups. I added my internal PC's ip addresses to the /etc/hosts file, and the problem disappeared.

However, why would the problem only start today? It's been running fine without any /etc/hosts entries for weeks now, and just today it started being ridiculous.

Any ideas?

It's possible your ISP's DNS is acting slow all of a sudden. Try 'ping <somesite>', how long does it take to look up the name?
