A new tagged build with no listed change details
ftpsrv has reached version v0.21.4, published on October 26, 2026. The release entry contains no detailed change notes or listed downloadable assets, so there are no specific fixes or feature additions to report for this build.
The project is a simple FTP server designed to run on a jailbroken PlayStation 4 or PlayStation 5 using an ELF loader. Its documentation also covers building the software for GNU/Linux systems, while the PlayStation-specific commands and payload usage apply to the supported console environments.
FTP access over port 2121
When running on a supported PlayStation, ftpsrv accepts FTP connections on port 2121. The project lists gFTP, FileZilla, curl and Thunar among the client software tested with the server.
These clients can connect to the server for transferring files between a computer and the console. The files available through FTP depend on the permissions and system environment of the device running the payload.
PlayStation-specific commands
ftpsrv includes several custom commands for PS4 and PS5 use. KILL stops the FTP server, while MTRW remounts /system and /system_ex with write permissions. These commands affect system mounts and should be used with care.
The SELF command toggles on-the-fly decryption of SELF files for an individual FTP connection. It is enabled by default. Because the setting applies per connection, one client session can change this behavior without changing the setting for other connections.
Known PS5 limitations remain relevant
The project documents a kernel issue affecting some PS5 firmware versions below version 4. Reading certain SELF files on those systems can cause the read system call to stall. This is a documented platform limitation, not a change announced for v0.21.4.
SELF files located at the root of the PS5, such as /SceSysAvControl.elf, cannot be decrypted directly. The documented workaround is to copy the encrypted file to /data/ first and then download it from that location, where ftpsrv can decrypt it during transfer.
Background for supported users
On PS4 and PS5, ftpsrv is deployed as a payload through an ELF loader. The README also documents an installation option for PS5 systems: when websrv is running, the server can be installed to disk and launched from a new item in the standard Sony shell interface. That workflow is specific to the documented PS5 installation setup.
ftpsrv is distributed under the GPLv3 or later license. Since v0.21.4 includes no detailed release notes, users should treat it as a new tagged build rather than expect a documented list of behavioral changes.
