Arista EOS devices file copy from this Solarwinds SCP server is sending a mod table of 0700 implying that the host has a umask of 007. This copies the file to Arista switches with only RWX permissions for the user who copied the file. When another user logs into the switch, they are unable to verify or install the software.
Are you able to adjust the umask to 002 so these can be copied to Arista switches with the appropriate mod table permissions? Or at minimum adjust the permissions of the files hosted to be 664.
