278012 - SYN flood when logging onto irc.mozilla.org/#mozillazine

Status: RESOLVED INVALID

(Other Applications Graveyard :: ChatZilla, defect)

Description

[Brian]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

Whenever I log on to irc.mozilla.org/#mozillazine with chatzilla, I get a SYN
flood warning from my firewall monitor. It does not do this on trillian or any
other irc channel. When this happens it closes ports off and restricts access
from my computer.

Reproducible: Always

Steps to Reproduce:
1.start chatzilla from firefox or web based app.
2.connect to irc.mozilla.org and join #mozillazine
3.SYN flood warning comes up and shuts down ports.

Actual Results:  
I have to restart to reopen ports and re-establish mail connection.

Expected Results:  
It should not be flooding or there should be a flooding control. Trillian has
such a control.

This is the silliest report I've seen for ages. :-P

Assuming you /do/ mean TCP SYN packets, there's no way ChatZilla can "flood"
them (let alone create them at all, beyond creating one single connection to the
server), and there's no link between SYN and flood protection within IRC clients.

That IRC Server scans your PC for open ports, nothing to worry about (also your
firewall tells something else, but let me assure you: You don't have to worry
about this). This has been done to limit attacks on users/irc servers by
compromised PCs.
