Undernet Routing Committee

Technical Requirements

Last Updated: 20031101


All Undernet server applications must be accompanied by authorization to run the server.This authorization must come from the NOC (Network Operations Center) or Network Administration of the HOSTING network. Such authorization may not be from the Domain administrative, technical, or billing contact, as in many cases these are not the individuals responsible for the site or the associated network. Rather, the responsible party must be the administrative/technical contact for the AUTONOMOUS SYSTEM. Please note that a route and autonomous system object must be present in the RADB routing registry!

NOC authorization

The NOC contact provided on the server link application will be contacted by the Routing Committee. The contact will then have 14 days to reply to the request for authorization. If verifyable authorization is received during that time, the application will be processed and reviewed by the Routing Committee. If the NOC contact fails to respond within 14 days,the application will be automatically declined.

Form of authorization and Bandwidth Requirements

The following is an extract from the text of the NOC contact authorization request:

We would request verification from you that you approve of the proposal for an Undernet IRC server to be run from your site (should the application be approved by the routing committee) and that you are aware of the potential network consequences involved in hosting an Undernet server. Please note that the Undernet being one of the largest IRC Networks in the world, the servers are often targets of large scale Distributed Denial of Service (DDoS) attacks, which can usually last several hours or even days with peak bandwidth usage of *multiple gigabits per second* and *tens of thousands of packets per second*. Indeed, it is guaranteed that the server will become a target of a DoS attack at some point. DDoS mitigation technologies should be considered (on your network or at the upstream level) as good steps to help prevent these attacks from harming your network and your business.

Following are the current AVERAGE bandwidth figures for Undernet servers. (if approved, the proposed server would be a Client-Leaf server). Bandwidth measurements shown are taken from a two week period in October 2000, and averaged

Server Type Number and Type of Connections Average Nominal Operational Bandwidth Average Burst/High-Traffic Bandwidth
HUB 4 Leaf Connections 1.042 Mbps 2.476 Mbps
Client/Leaf 1 Hub Uplink 4000 Clients 3.148 Mbps 7.141 Mbps

To this end, only sites with a total aggregate transit bandwidth greater than 100 Mbps will be considered. For the purposes of this document, transit is defined as bandwidth which is globally accessible. It is the globally accessible "international" bandwidth which counts as transit, for this purpose.

If you are fully aware of the implications of such a server, and approve of this server being potentially hosted by your site please respond to this message withing 14 days indicating your approval.

The bandwidth consumption averages shown are based on ONLY Undernet traffic. This does not include traffic and bandwidth usage for the hosting site's normal business operations. This factor should be born in mind when determining whether a site has available resources to host an Undernet server. Generally, any site which consumes 70% or more of their available bandwidth for their general business operations will not be well suited to running an Undernet server.

Machine/Hardware requirements

All Undernet servers must meet certain minimum hardware standards in order to efficiently operate on the Undernet IRC Network. The bare minimum standards are as follows: Minimum 512MB RAM (1 GB or higher highly recommended)

For for x86-based machines, a minumum of 600MHz is required. for Sparc, the machine should be a Ultra-10 or better. Other platforms should run a comparable, or better, system. The Operating System kernel must be configured to allow a minimum of 4096 open file descriptors per process, and must support at least 4000 undernet user connections.

Server must be a DEDICATED machine to serve as an IRC server. IRCU should be listening on (at least) port 6667. No other services open to the Internet (as in "") may be run on such a machine. Servers MUST NOT be running useless services for an IRC server like : inetd, rpc.statd, apache, telnetd, webmin, ftpd, etc... Any service running on the server other than ircu and sshd like snmpd, sendmail/postfix, zebra/quagga or even syslogd must be filtered or listening on localhost or your out of band network only. This being said, it is also quite obvious that the SSH service should be firewalled or listening only on your out of band network. We recommend that you use a firewall on the machine and even at any upstream level so that you can limit access and to a certain extent, some attacks on the machine.

Further it is required that the server run a NTP daemon for time synchronisation. New client servers will have one week from the beginning of their test link to properly configure ntpd on their server, since they will not have the proper IP addresses prior to the approval of their application. Until they have ntpd running and synchronized with at least one Undernet hub, they must leave RELIABLE_CLOCK turned off. If more than one week is required, the test link admin must contact the Routing Committee secretary, who may, at his or her discretion, extend the time for fulfillment of this requirement. However, the server must have ntpd properly configured prior to the vote for full link status.

When a user connects to undernet, a DNS reverse lookup request is made. Since these kind of lookups are quite time hungry, optimizing their speed is necessary for any middle-sized server (2000-8000 clients). It is recommended that the server run the latest version of any cache-only name server (bind8/bind9/djbdns/...) and accept requests from ONLY localhost.

Administrator Requirements

The admin of the prospective server must have at least a general competence with Unix and the running of an IRC server, to include at least a basic understanding of the server configuration file, and use of the C compiler and associated utilities for the particular platform in use. The Routing Committee will offer general guidance in the configuration of the server, but will not "hand-hold" an admin on every detail.

Recently, Undernet has received reports that a non-affiliated person has been sending out requests to large numbers of network & hosting providers asking for sponsorship of resources to link a server to our network.

We do not have full visibility of where all these requests have been sent but understand they likely come from either the name Nikolaos Kostopoulos (GMail) or Alex Koukoulas (admin@underlab.org)
-- both the same individual.

Please be advised that is person is not currently, and never has been, an official representative of Undernet. He is not acting on our behalf and his e-mails has been misrepresenting us and providing misleading & incorrect information.

If you have received one of these requests from him, please let us know at r-com@undernet.org and disregard the request.

We appreciate your help and we apologize if his requests caused any undue hardship.
