Virtualmin – FTP/SFTP File Writing Errors

If you’re using Virtualmin on your servers and have a few odd FTP error messages (happened for me using SFTP too), then it’s one of three things.

  • Disk quota for the hosting account has exceeded
  • Server has ran out of memory
  • The configuration options below need to be set in /etc/proftpd.conf

As mentioned above, I found that these two options added into /etc/proftpd.conf fixed the file write issue in some cases:

AllowRetrieveRestart on
AllowStoreRestart on
