Hi,
The ident-protocol is a legacy from the old days when most of us would use dialup connections to mainframes, and run our irc clients (on said mainframe) through terminal clients...

Since there would be a large number of users from the same IP address, a service was implemented where you could query which username had initiated which connection (based of port numbers). On irc servers, you'd see this as the part of !@. In cases where there would be no valid ident-response, the part would usually be prefixed with the tilde-sign (~). I don't see much issues with reducing the ident-timeout, as it's legacy these days. In the rare event that valid requests would start to timeout, you could try to increase it slightly, or adjust usermasks accordingly.

For those curious to the protocol, it's documented in RFC1413.

... or an ident-query timing out.

This is what he was told, in #eggdrop channel :

Eggdrop uses ident for authentication. It queries all connections for an ident response
If the client connecting doesn't have an ident server running, you have to wait the timeout

Thought you might like to see it.

I believe you can reduce the ident-timeout setting to mitigate the ident-query, since the ident-service really isn't used much these days...

No one in the channel mentioned that. You've caused me to go look.
Is this what you refer to? :

# This setting defines the time in seconds the bot should wait for ident reply
# before the lookup fails. The default ident on timeout is 'telnet'. A value of
# 0 disables the ident lookup entirely.
set ident-timeout 5

No one mentioned that setting, there on the channel. I wonder why ....
Are there any negative consequences to setting it to zero ?

Thanks for jumping in.

The delay would probably be either due to DNS resolution, or an ident-query timing out. I believe you can reduce the ident-timeout setting to mitigate the ident-query, since the ident-service really isn't used much these days...

yes. only problem on first step(auth).

after that, works success all.

Ok.

I don't find it to be a problem - perhaps a minor inconvenience and an item of curiosity. I don't know why that delay is in there after connection ... I suppose we have to ask one of the folks that writes the code.

Sometimes they are in here.

Mostly though, if you want to ask one of them, you might try the Freenode irc network, and join the channel: #eggdrop

...
client askin "username" to me in like 5~15 seconds

I find this to be typical. Same if I use : /ctcp botnick chat

There just seems to be some lag there.

But ! Once logged into the bot - with either of the above methods - the response to commands is just as quick as when logged in via /dcc chat botnick .

Do you find the same?
