Trouble connecting to Slack IRC

[Steve Barber]

Any idea if I'm doing something wrong, or if there's just some weirdness with this IRC server? SSL, with a password.

The exception is from a bug reported last week in 2.0.1 where servers with non-standard 004 responses break ServerInfo. You can safely ignore it until 2.1 comes out

Your problem is the line :slackbot PRIVMSG myname :SSL connection required

In your code your using TLSCapHandler which connects to the server over a plain unencrypted connection, and if the server supports it (yours doesn't), upgrades the connection to SSL. What your server seems to be wanting is a SSL connection from the start.

Just replace this:
.addCapHandler(new TLSCapHandler(new UtilSSLSocketFactory().

trustAllCertificates(), true))

with this:

.setSocketFactory(new UtilSSLSocketFactory().trustAllCertificates())

You'll might have to change the port as well to one of the servers SSL ports

Yes, indeed the server does very much want an SSL connection from the start.

Thanks very much! It is connected now.

If you are interested in testing your 2.1 ServerInfo parsing fix against the server I'm using, just go to https://slack.com/ and create yourself an account, and enable IRC connections. If you don't know Slack, it is getting popular in some circles. I suspect I won't be the last to want to connect to it with PircBotX.
