Two things to keep in mind when updating IOS on this router: 1) IOS 11.0 is the minimum IOS that has been tested for Y2K compliance 2) You only have 4MB of flash, so you may have trouble finding an 11.0 image to fit in that space, considering that you may be running multiple protocols on it. You have 6MB of RAM, and 4MB of flash. IP images and IP/IPX images will fit into 4MB of flash, but anything beyond that (Desktop, which is IP, IPX, ATalk, DEC, etc), IP/IPX/IBM, and IP/IBM all require 8MB of flash. Good luck, -rb ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Fire: South Korea Financial District
by Sean Donelan 21 Feb '00

21 Feb '00

There was an underground cable fire in the main financial district in South Korea. Several banks and at least one ISP lost high-speed telecommunications service from Friday through Sunday. Although only 33,000 lines were affected, due to the location, they tended to be the very high value lines. A full investigation has been promised. Speaking of full investigations, has anyone heard whatever happened to the investigation into the fire at the telco central office in Toronto's financial district last year?

[SNIP - directions on booting from ROM] Be sure your ROM supports the new IOS rev or it will not come back properly. Also note, a 2501 booted from ROM does not have full functionality. For instance, most older ROMs did not support FR sub-interfaces. In fact, some older ROMs did not even support ip routing, so you had to use the "ip default-gateway" command or have a TFTP server on the same network. (The default-gateway command is ignored if ip routing is running.) > Jon Lewis *jlewis(a)lewis.org*| Spammers will be winnuked or TTFN, patrick -- I Am Not An Isp - www.ianai.net ISPF, The Forum for ISPs by ISPs, <http://www.ispf.com> "Think of it as evolution in action." - Niven & Pournelle (Enable?

the original purpose of the SRV RR was to let each network element potentially have its own whois server. this makes the assumption that DNS available, and some people didn't like that. -- Paul Vixie <vixie(a)mibh.net> SVP for Internet Services, MFNX M.I.B.H.

Issue on establishing local/private IRR database
by Yu Ning 21 Feb '00

21 Feb '00

Hi, We plan to establish a local/private IRR in order to control the RS in our local/private IX, but we are quite puzzled by the relationship of the local IRR and RADB. Can anyone answer my following question ? 1. Is partial database ok, and enough ? Because we run only a domestic IX, so i think we need only maintain the RPSL database of our domestic ISP, and we need not mirror the 5 standard IRRs, such as RADB, CW, RIPE, RPSL database. 2. The relationship between our local IRR, and standard IRRs. Once we establish the local IRR via IRRd of MERIT, shall we register all the data of local RPSL database in one of the global registries,such as RADB ? Will RADB accept our local IRR, and start to mirror our data ? Or our data exist only in our local/private database, and no one care about us (it seems this scenario is little away from the spirit of global IRR) regards, Yu Ning Networking Dep.

SMTP in distributed DOS
by Dirk Harms-Merbitz 20 Feb '00

20 Feb '00

SMTP bounces can be used in yet another form of Denial Of Service attack. Just imagine what happens when some script kiddie uses a few ten thousand trojaned cable/dsl connected home computers to send email to tens of thousands of domains and they all bounce back to your mail server! Why don't we all just turn SMTP bounces OFF? Like return-receipts, the information content in bounces is very low. A database would be much more efficient if you just want to know wether an email address is spelled correctly. Resending the entire message after adding a few hundred bytes is just idiotic. Escpecially if the attacker only has to send one message to generate 100 bounces. We are currently seeing this first hand: Our real mail.power.net is at 207.151.19.8. The attacker is sending individualized emails with faked headers that contain "mail.power.net (unverified [209.26.14.22])". The recipient computers are dumb enough to send their bounces to the real mail.power.net. This is a DOS because the innocent mail server a) gets millions of bounces and b) might get black listed on various "anti-spam" lists.

whois-servers.net
by William Allen Simpson 20 Feb '00

20 Feb '00

Acting on an old memory, I found that Rodney Joffe already registered whois-servers.net last year. Can this be leveraged to build the needed distributed whois network? I guess I've just become lazy and use geektools whois web page, because it finds the right whois server for me. We should have built the redundant server network long ago.
