This doesn't help 12.0.xS :( That's what I feared, and the firewall feature is so broken in 12.3 that it makes it unusable for the moment; I rolled back to 12.2(T) including for lab, and 12.2(T) still uses SSH 1.5 :-( Jul 27 08:48:02.805 PST: %SSH-5-ENABLED: SSH 1.5 has been enabled cisco7507#sh ssh Connection Version Encryption State Username 1 1.5 3DES Session started dude Michel.

What ever happened to... MARP (Multi-Access Reachability Protocol)
by Sam Stickland 27 Jul '04

27 Jul '04

Last draft appeared to be http://www.watersprings.org/pub/id/draft-retana-marp-02.txt which expired Sept 2003 (Abstract: defines a protocol to quickly determine the existence or aliveness of devices attached to a shared media (broadcast) subnet.) First read about it in this presentation, where it was billed as an alternative to fast hellos: http://routing.internet2.edu/wg-meetings/20021029-I2rwg-slides/20021029-dau… The idea was that a switch could notify connected routers of link failures immediately - there would be no need to wait for the dead and hold-timers to expire. Is this idea still flying? There appears to be very little on the net about it, except what I've mentioned above. Sam

No real-world production application; first, it has 16 async lines, you would expect to be able to have two different users use two of them at the same time. This is what terminal servers are for. Second, if you need to use one of the serial ports to access the router with PPP, have an access-list to restrict telnet/SSH access, log anything, you're SOL. The 2511 is a perfectly good CCIE Lab terminal server though, no need for SSH. For what I have read, lots of people here could use a little practice. There's this story about the guy flying 10,000 miles coming to SJ to take the lab (before a testing center opened in Asia) and could not get through the first line of the first lab question (which is to configure the 2611 to access all the other devices using reverse telnet) and flew back home with a brilliant 0 points. There's no point using SSH when the router's enable password is "cisco", or is there? Michel.

Same here. There is more CPU power in a dishwasher than in a 2611 these days. Dumb Cisco/SSH question: how do you get a banner to display _before_ the ssh user/pass prompts? Michel.

(Ob Humor: I read nanog via the web-based archive. Randy doesn't have a .signature. I *was* going to google for his email. Such irony, timing.) IIRC, 2511's look the same as the aux on any Cisco box. For those, it is "CTRL-carat x", where carat is '^', shift-6 on most western keyboards. Be careful not to just hit return next, since that is "continue" to telnet, defeating your correct "break" sequence's intentions. briand
