Issue/Introduction

We are trying to setup a new DC in a different Data Center. I am running wget to pull the DC installation package from the DA.

wget -P /tmp/ --no-check-certificate -nv http://<DA_HOST>:8581/dcm/InstData/Linux/VM/install.bin
WARNING: cannot verify <systemHost> certificate, issued by ‘/CN=<Company> Private Issuing SHA256 CA G1’:
  Self-signed certificate encountered.
2021-11-30 20:49:23 URL:https://<systemHost>:6082/php/uid.php?vsys=1&rule=4&url=http://<DA_HOST>%3a8581%2fdcm%2fInstData%2fLinux%2fVM%2finstall.bin [6143/6143] -> "/tmp/install.bin" [1]

The download seems fine and finishes without error, but the file size seems too small:

[[email protected]<New_DCHost> ~]# ls -la /tmp/install.bin*
-rw-r--r--. 1 root root 6143 Nov 30 20:49 /tmp/install.bin

Why is the downloaded install.bin file for a Data Collector install always too small? Always the same size?

Environment

All supported DX NetOps Performance Management releases

Cause

Environmental issue prevents successful file transfers to the system.

Resolution

The cause was found by running the 'cat' command against the install.bin file. When running that we see output in ASCII text, not the expected install.bin code. The text present indicates an MFA (Multi-Factor Authentication) issue preventing access to the system.

Testing using scp and curl to gather or transfer the file fail as well. No file transfers are successful to the target system.

Determine with system administration why the system is preventing successful file transfers.
