Cant u use namebased vhosts? Or different ports?

Can anyone tell me what is the limit for how many IP aliases can be setup on the same ethernet card? Is there a global limit for the total number of aliases in the OS? To be clear: one needs 128 IPs (for irc vhosts) to be setup on one server. Is that impossible?

Re: how many IP aliases
Ah I assumed u meant irc vhost servers Still leaves there question why would each psync require a specific IP? If the IRC network you connection to limits on connections per IP e.g. QuakeNet ( which all should do ). You just need to apply for a trust for X connections and your all sorted. Using multiple IP's for such a use would be totally wasteful. Steve - Original Message - From: Anton Alin-Adrian [EMAIL PROTECTED] Different ports? Why would be using different ports different? They (users) need to go out to irc with a different IP each time they connect. In order to do that, psybnc needs to use that specific IP when connecting outside to the IRC server. I don't see how different ports will change this situation. Nambased vhosts work for web, I guess, but not for IRC. Let one correct me if I am wrong.

To be clear: one needs 128 IPs (for irc vhosts) to be setup on one server. Is that impossible? I don't know the exact max. number for aliases on a single nic, but I do know that 128 addresses isn't a problem - depending of course on your setup such as ram, cpu, board and last but not least, nic.

Re: how many IP aliases
There is no upper limit. ok. I do know that 128 addresses isn't a problem - depending of course on your setup such as ram, cpu, board and last but not least, nic. Don't do it on a $20 nomame-nic. It doesn't make any difference to the NIC. Correct me if I'm wrong, but addresses to a interface is 'managed' by SIOCAIFADDR and yes, that has noting to do with the nic itself. But a server-box with a $20 noname-nic with a small amount of ram, a slow cpu and 128 ip-aliases sounds more like a academic exercise (even though it can be done) than a practical solution. Again correct me if I'm wrong. respectfully /per [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

It doesn't make any difference to the NIC. Well I understand it's just a linked list with aprox 128 nodes. That should be OK on decent RAM and CPU. Correct me if I'm wrong, but addresses to a interface is 'managed' by SIOCAIFADDR and yes, that has noting to do with the nic itself. They have nothing to do with NICs, they have to do with OS implementation. NICs talk on ethernet level, and I don't know any NIC's designed with special hardware for handling IP aliases. Intel's FXPs rule, because they even do CRC and QoS with microchip:). Probably his point was no-name hardware with small buffers may add to the latency. Thank you all so much!
