I have a remote router, R1 that I can not access because VTY password is
not known. The SNMP with Write access is configured on the router R1.
R1 ----------- R2
Linux server with "SNMPSET" command
I can not send a config file to R1 with a VTY password using the
"SNMPSET" command from my linux server as the TFTP source IP is not
correctly set on the R1 (command "ip tftp source-interface" is not
configured). I can ping R1 from my linux server, SNMPwalk works and I
can telnet to R1 (I can not login as the VTY password is not known).
There is full IP connectivity between R1 & R2 and I know for sure that
R1 can get a config file, stored in flash of R2 via TFTP if I make the
R2 TFTP server with the command, "tftp-server".
I need to know how to use the SNMPset command on my linux server to
instruct the R2 to send the config file to R1.
Is this possible?
I have tried the below command but it did not work.
snmpset -c <RW community> <routerIP> 220.127.116.11.18.104.22.168.1.53.#.#.#.# s conf
#.#.#.# <- TFTP server IP = R2
<routerIP> = R1
Can you please help on this?
