​It asks me for a password. Which kind of authentication is used?​

[tryton-dev] Brute force attack on ssh

[Cédric Krier]

Hi,

The Tryton server receives very often brute force attack on ssh. To
limit the effectiveness of such attack, I have setup a rule that prevent
one IP address to make more then 5 new connections on 120 seconds.
This means that if you do an 'hg npull' over ssh, you will be banned for
120 seconds. To avoid such case you must create first a master
connection using: 'ssh -M -N hg.tryton.org'

The rule happens to be pretty effective. In few minutes, the rule
dropped already about 15 IPs.

Sorry for the inconvenient but the Internet is a wild space and we must
protect ourself.

Regards,
