1OpenBMC host console support 2============================ 3 4This document describes how to connect to the host UART console from an OpenBMC 5management system. 6 7The console infrastructure allows multiple shared connections to a single host 8UART. UART data from the host is output to all connections, and input from any 9connection is sent to the host. 10 11Remote console connections 12-------------------------- 13 14To connect to an OpenBMC console session remotely, just ssh to your BMC on port 152200. Use the same login credentials you would for a normal ssh session: 16 17 $ ssh -p 2200 [user]@[bmc-hostname] 18 19 20Local console connections 21------------------------- 22 23If you're already logged into an OpenBMC machine, you can start a console 24session directly, using: 25 26 $ obmc-console-client 27 28To exit from a console, type: 29 30 return ~ . 31 32Note that if you're on an ssh connection, you'll need to 'escape' the ~ 33character, by entering it twice. 34 35Logging 36------- 37 38Console logs are kept in: 39 40 /var/log/obmc-console.log 41 42This log is limited in size, and will wrap after hitting that limit (currently 43set at 16kB). 44
