Examples

The following example is output from the debug ip scp command. In this example, a copy of the file scptest.cfg from a UNIX host running configuration of the router was successful.

Router# debug ip scp
4d06h:SCP:[22 -> 10.11.29.252:1018] send <OK>
4d06h:SCP:[22 <- 10.11.29.252:1018] recv C0644 20 scptest.cfg
4d06h:SCP:[22 -> 10.11.29.252:1018] send <OK>
4d06h:SCP:[22 <- 10.11.29.252:1018] recv 20 bytes
4d06h:SCP:[22 <- 10.11.29.252:1018] recv <OK>
4d06h:SCP:[22 -> 10.11.29.252:1018] send <OK>
4d06h:SCP:[22 <- 10.11.29.252:1018] recv <EOF>

The following example is also output from the debug ip scp command, but in this example, the user has privilege 0 and is therefore denied:

Router# debug ip scp
4d06h:SCP:[22 -> 10.11.29.252:1018] send Privilege denied.
