I just bought a cisco 2600 router which is giving a message
"%Error opening tftp://255.255.255.255/cisconet.cfg (Timed out)
%Error opening tftp://255.255.255.255/router1-confg (Timed out)
%Error opening tftp://255.255.255.255/router1.cfg (Timed out)"
How do i get rid of this message and what does it indicate.
Q2 Also i am not able to save my running config by running a WR MEM command
every time i reboot the router it is lost what could be the possible problem.
The service config instructs the router to attempt to read a config file from the TFTP server. The attempt to read various permutations of the config name is what is generating the errors in your original post. Unless you intend to have the TFTP server set up to provide the config to the router at boot time (and very few people do that) then the advice to configure no service config is good advice and it will stop the errors that you reported.
Based on your symptoms it is likely that your config register is set to 0x2142 (which is likely the result of someone doing password recovery). The significant digit is the 4 which instructs the router to ignore the stored config in NVRAM at boot time. If you change the config register to 0x2102 then it will instruct the router to read the stored config (startup-config) at boot time.
Try the command from the config mode: no service config.
For the saving config check the config register value.
You can see it in a show version
It's the last line of that output:
example: Configuration register is 0x2102
To set the config register, in config mode: config-register VALUE
