1) It doesn't matter how long they have been connected
2) This is a client side command you are using! It is not under the control of the IRCd.

That is normal, if you don't want your opers to be able to see this information... uh, don't oper them.

TigerKatziTatzi wrote:/dns nickname of a recently connected user will give u dns entry

As above, this is a client side command-- how long they have been connected has nothing to do with it. It is more likely whether they have mode +x set! I strongly advise you to do some more reading as to how DNS actually works and what it is, and then read mIRC's helpfile (I assume you use mIRC)

Code: Select all

/dns [-ch] [nick|address]
Resolves an address. If mIRC sees a "." in the name you specify it assumes it's an address and tries to resolve it. Otherwise it assumes it's a nickname and performs a /userhost to find the user's address and then resolves it. If you specify an IP address, it looks up the host name.

You can queue multiple /dns requests, and you can view the current queue by using /dns with no parameters.

The -c switch clears all currently queued DNS requests, except for the one currently in progress.

The -h switch forces /dns to treat the parameter as a hostname.

Note: Due to way the DNS lookup works, any DNS related functions currently in progress eg. connecting to a server, must be resolved before subsequent requests. This means that if a prior DNS is having problems resolving, subsequent DNSs have to wait until it times out before they can be resolved.

Quoted direct from mIRC's helpfile-- mIRC's /dns command is in no way related to UnrealIRCd's /dns command- mIRC's one gets used first because it's client side! You will only get the IRCd's DNS command if you use /quote dns or /raw dns as this overrides mIRC's inbuilt commands and sends it straight to the server.

so far about /dns nicknames ....................

only vhost users are able to be resolved on long term. but this will show then ip of ur dns server

Say what? vhosts are usually used to make the +x host "prettier". They also usually don't resolve.

Just to add, the response from /helpop ?dns

Code: Select all

***** Dns *****
 -
 Returns information about the IRC server's DNS cache.
 Note, since most clients have a builtin DNS command,
 you will most likely need to use /raw DNS to use this.
 There are also 2 other variants:
 'DNS l' will show you the DNS cache entries
 'DNS i' will give you details about the nameserver config

Syntax: DNS [option]

The ones that aren't resolving, more than likely they have +x set by the looks of their hostnames.

As for the mindforge ones, check your BIND settings. Looks like you've got everything set to resolve back, which probably isn't a good thing. Not that it's gonna do much as they can just DoS your server anyhow, i'm betting that that IP is pointing to your server, not to you?

Yup...

C:\Documents and Settings\Harry>nslookup netadmin.mindforge.org
*** Can't find server name for address 10.1.1.1: Non-existent domain
*** Default servers are not available
Server: UnKnown
Address: 10.1.1.1

Non-authoritative answer:
Name: netadmin.mindforge.org
Address: 69.25.212.134

And then:

C:\Documents and Settings\Harry>nslookup http://www.mindforge.org
*** Can't find server name for address 10.1.1.1: Non-existent domain
*** Default servers are not available
Server: UnKnown
Address: 10.1.1.1

Non-authoritative answer:
Name: http://www.mindforge.org
Address: 69.25.212.134

My guess, check your BIND settings on the server.

remove the ablity for them to -x themselves.

on my servers regular users do not have the ability to change usermodes themselves.

@'the ircd died'... well if it crashed, and the ircd is not modified, report it on bugs.unrealircd.org (don't forget to read the part 'how to report a bug' under 'main'). Thanks.

we did. u've got an report made by duplex. but i want to do some defined testings on a testnet during this week. we hadn't any chance to do it last weekend. we'll keep u informed about results. but mainly looks like a bug on too many triggered events to join them in viruschan. but we'll check this out.
