Portable mode

SFTPGo allows to share a single directory on demand using the portable subcommand:

sftpgo portable --help
To serve the current working directory with auto generated credentials simply use:

sftpgo portable

Please take a look at the usage below to customize the serving parameters

In portable mode, SFTPGo can advertise the SFTP service and, optionally, the credentials via multicast DNS, so there is a standard way to discover the service and to automatically connect to it.

Here is an example of the advertised service including credentials as seen using avahi-browse:

= enp0s31f6 IPv4 SFTPGo portable 53705                         SFTP File Transfer   local
   hostname = [p1.local]
   address = [192.168.1.230]
   port = [53705]
   txt = ["password=EWOo6pJe" "user=user" "version=0.9.3-dev-b409523-dirty-2019-10-26T13:43:32Z"]
