Issue/Introduction

Attempting to capture configurations via SNMP/TFTP is resulting in a failure indicating write failed.

Upon investigating further with a tcpdump:

tcpdump -i any -w /tmp/capture.pcap

The capture shows (for TFTP protocol):

TFTP Write Request, File: SCM_0x14124d, Transfer type: octet, blksize=8192

TFTP Error Code, Code: File not found, Message: File not found

Resolution

The TFTP Server needs to properly be configured to allow writes.

For example if using in.tftpd:

The tftpd.service file needs to include the proper -s /tftpboot directory in the Exec line.

Restart the service once properly configured and captures should start working properly.
