[[PageOutline]] = How do I connect to an MF/PL server located at Sunset Park via the serial port? = Note: if you are trying to connect to a server in our XO/Bandcon, see [wiki:xo_serial_access our XO serial access page]; for Telehouse see [wiki:telehouse_serial_access Telehouse serial acess page]; for Koumbit see [wiki:koumbit_serial_access Koumbit serial access].. == Serial Console physical setup == In Sunset Park we have an 8 port USB to serial adapter using the pl2303 chipset that is plugged into our office router (ida.mayfirst.org. They 8 ports are allocated: * `yaqeen` (Cable 1: ttyUSB0) - alfredo/praxis project * `sittingbull` (Cable 2: ttyUSB1) * NOT IN USE (Cable 3: ttyUSB2) * NOT IN USE (Cable 4: ttyUSB3) * NOT IN USE (Cable 5: ttyUSB4) * NOT IN USE (Cable 6: ttyUSB5) * NOT IN USE (Cable 7: ttyUSB6) * NOT IN USE (Cable 8: ttyUSB7) The serial consoles of the attached machines are all remotely accessible (to properly-authenticated people), and they are also logged and timestamped. We are using [http://cmrg.fithhorseman.net/wiki/cereal cereal] to do this cleanly and easily. == How to connect == In order to connect via serial console to one of the servers named above, ssh into `ida.mayfirst.org` as ''servername''`-console` For example: {{{ ssh -t zapata-console@ida.mayfirst.org cereal attach melanie }}} Would give you full read/write access to the console on `melanie`. The SSH RSA host key for `console.mayfirst.org` should have a fingerprint of: {{{ a5:67:26:83:0d:43:2c:32:0a:c5:3e:5c:0a:8b:32:10 }}} We can also setup additional users that have read-only access to the sessions created by each of these usernames, should that be desirable. You can request such access by creating a [/newticket ticket]. == Setting up a new console user == To setup a new console user (this is something only admins can do), do the following as `root@ida`: {{{ adduser --disabled-password --gecos='fred console user,,,' fred-console cereal-admin create fred /dev/ttyUSB2 115200 fred-console fred-console cereal-admin start fred }}}
