I have a Ubuntu machine which acts as a TFTP Server. I want to configure my cisco ios routers to take configuration from this TFTP server at boot time.

I have a few doubts- Where do I store the configuration file for my cisco router in the TFTP Server? Currently, I have created two temp folders in /var/lib/tftpboot- 

automation@automation:/var/lib/tftpboot$ ls -l
total 8
drwx------ 2 tftp tftp 4096 Mar 31 15:37 ExrZHRa-incoming
drwxr-xr-x 2 root root 4096 Mar 31 15:52 TXJla-outgoing

automation@automation:/var/lib/tftpboot$ tree
.
├── ExrZHRa-incoming [error opening dir]
└── TXJla-outgoing
    └── R1.txt

2 directories, 1 file

As per Cisco's documentation, this is the syntax to get a file from TFTP server- 

copy tftp: [[[//location ]/directory ]/filename ] nvram:startup-config 

Example:
Device# copy tftp://server1/dir10/datasource nvram:startup-config

As per my understanding, the location will be IP of my TFTP Server and filename will be the actual config file I want to load. But what should be configured in the directory? I tried with /var/lib/tftpboot/TXJla-outgoing but it didn't work. Error-

  • Wrong site, I'm afraid. You're looking for [ubuntu.se] instead. This site is for programming related questions, not general computer or OS support. You can find more information about this site in the [help]. – Ken White Mar 31 '19 at 22:46

Shouldn't it be just

copy tftp://192.168.1.1/R1.txt running-config

It looks like you are using tftp-hda. Did you follow this guide ? https://medium.com/@Sciri/configuring-a-tftp-server-on-ubuntu-for-switch-upgrades-and-maintenance-caf5b6833148

  • No, because `R1.txt` resides inside of the `TXJla-outgoing` folder within `tftproot.` – Frak Jun 07 '19 at 19:30

Try this:

copy tftp://192.168.1.1/TXJla-outgoing/R1.txt nvram:startup-config

The URL of anything you download via TFTP starts from the root of your TFTP server which is /var/lib/tftpboot
