And say automation tooling, maybe zero-touch conf, can remain unchanged when you decide to change OOB hardware. For rest of the list, how conserver works is that you ask it to retain persistent ssh to given ip+port and then offer multiplexed connection to that by some word. We generate conserver configuration from database, and use would be something like this ╰─ console r21.lab console: ambiguous console abbreviation, `r21.lab' choices are r21.labxtx01.us.bb_re1, r21.labxtx01.us.bb_re0, r21.labxtx02.us.bb ╰─ console r21.labxtx01.us.bb_re0 [Enter `^Ec?' for help] [no, y...@eng0.dllstx09.us.to.gin.ntt.net is attached] [bumped y...@eng0.dllstx09.us.to.gin.ntt.net] r21.labxtx01.us.bb-re0 (ttyd0) login: (here ytti was already on console, so I bumped him off, so I can continue working on the console). Now you don't need anything from your console server, but ability to offer console over IP+Port. It is very nice separation of concerns. We also have script which logins every day to every console port, and expects to see shell prompt, so that we actually know that the console works, when we need it. Now when it comes to OOB hardware CAPEX, in my world it doesn't matter at all, when DC is asking 150USD/MRC for cross connnect, cost of OOB hardware is just immaterial .So we opted to buy device which our tooling supports, people are comfortable working with and can support wide array of WAN options, doesn't have external PSU brick, can do multipoint DMVPN/IPSEC call-home style, so we don't need to have stable or known IP. To that effect, we chose Cisco4331. We have four BGP sessions per Cisco4331, 2 per hub, and on-band + out-of-band per hub. We prefer out-of-band connection, but will revert back to on-band, which is useful if there are issues in 3rd party non-fate-sharing 3rd party connection. -- ++ytti ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/

For software on that sort of setup, this is really great: https://www.conserver.com/ For a neater solution, these folks have all kinds of neat USB -> many serial port options: http://usbserial.com/ Can’t say enough things about ConServer. The logging is awesome, multi-user is super-handy. It beats all of the software I’ve seen in proprietary terminal server hardware. I bet you could also pick up something like Xylogics Annex III super cheap on Ebay too (if you don’t mind telnet instead of ssh!).

Re: [c-nsp] Console connections
We are trying a somewhat-radical new strategy. For our newest rack, we bought a Raspberry Pi Model 3B. It has four USB ports, and into each port we plugged a dual-headed USB to RS232 adapter, for a total of 8 ports. So far, so good. The main benefits are ease of use (our team can use the same tools they use on their laptops) and cost (100-150 USD total for the setup I just mentioned). The gotchas are that it only has one inbuilt Ethernet port and it does not have built-in support for redundant power. But we are using this only for emergencies, and we access the site once every few months anyway, so we were willing to make that concession. -- Hunter Fuller Network Engineer VBH Annex B-5 +1 256 824 5331 Office of Information Technology The University of Alabama in Huntsville Systems and Infrastructure On Thu, Jan 31, 2019 at 4:03 PM R.
