Description
Special login can be used to access another device (like a switch, for example) that is connected through a serial cable by opening a telnet/ssh session that will get you directly on this device (without having to login to RadioOS first).
Setup
For demonstration we will use two CableFree devices and one PC.
Routers R1 and R2 are connected with serial cable and PC is connected to R1 via ethernet. Lets say we want to access router R2 via serial cable from our PC. To do this you have to set up serial interface proxy on R1. It can be done by feature called special-login.
First task is to unbind console from serial simply by disabling entry in /system console menu:
[admin@CableFree] /system console> print Flags: X - disabled, U - used, F - free # PORT TERM 0 X serial0 vt102
Next step is to add new user, in this case serial, and bind it to the serial port
[admin@CableFree] > /user add name=serial group=full [admin@CableFree] > /special-login add user=serial port=serial0 disabled=no [admin@CableFree] > /special-login print Flags: X - disabled # USER PORT 0 serial serial0
Now we are ready to access R2 from our PC.
admin@CableFree:/$ ssh serial@10.1.101.146 [Ctrl-A is the prefix key] R2 4.0beta4 R2 Login: [admin@R2] >
To exit special login mode press Ctrl+A and Q
[admin@CableFree] > [Q - quit connection] [B - send break] [A - send Ctrl-A prefix] [R - autoconfigure rate] Connection to 10.1.101.146 closed.
To fix this problem you need to allow access bootloader main menu from <any> key to <delete>:
- enter bootloader menu
- press 'k' for boot key options
- press '2' to change key to <delete>
What do you want to configure? d - boot delay k - boot key s - serial console n - silent boot o - boot device u - cpu mode f - cpu frequency r - reset booter configuration e - format nand g - upgrade firmware i - board info p - boot protocol b - booter options t - call debug code l - erase license x - exit setup your choice: k - boot key Select key which will enter setup on boot: * 1 - any key 2 - <Delete> key only your chaoice: 2
