Hi, hoping someone here from Comcast can help me. I need to be able to login Comcast Looking Glass router in NY to check on some route advertising but the username and password that was previously working for the LG no longer seems to work. Host: route-server.newyork.ny.ibone.comcast.net Username: rviewsxr Password: rviews and I also tried rviewsxr If anyone knows the current login info I would appreciate it. P
BGP.tools super LG any help? They probably have a lot of feeder sessions sitting behind Comcast which could accomplish the mission? On Wed, Jan 8, 2025, 12:42 PM Paulo J Amaral via NANOG <nanog@nanog.org> wrote:

Hah! I ran into that same issue earlier in the week — a few places (including some notes that I had) implied that it was a username of "rviewsxr" with a blank password - but also that many SSH clients, including OpenSSH, deal poorly with blank passwords. I had assumed that that was what I was running into, and so spent some time trying to figure out if it was a blank password issue, before I became distracted by a squirrel W

possibly you need some other flags to the ssh client: -oKexAlgorithms=+diffie-hellman-group1-sha1 (server here only offers that key exchange algorithm) -oMACS=+hmac-sha1 The server here appears to be a very old cisco type thingy :( (I didn't figure the passwd part out, docs appear to say the passwd should be: rviews - perhaps some security person made them add more entropy? :) )

Yah. My notes has claimed that it was an empty password, but my notes might be wrong. Perhaps either they set one, changed the existing one, or the equivalent of "PermitEmptyPasswords no" was set… Whatever the case this seems like a question that Comcast can answer… W

Quick update: I just spoke with someone at Comcast, and they let me know they have identified a problem with the authentication and are working to resolve it. W On Thu, Jan 09, 2025 at 1:11 PM, Warren Kumari <warren@kumari.net> wrote:
