gFTP vs Serv-U FTP Server

gFTP is a free, multithreaded file transfer client for *NIX-based machines, known to run on Linux distributions. It supports FTP, explicit and implicit FTPS, SSH2 SFTP, and FSP. Users can choose a GTK interface or a text interface, launched with the gftp-gtk and gftp-text commands. The text interface can download a directory and its subdirectories in one run, and transfer automation is listed. SSH2 SFTP support requires the OpenSSH client. For FTPS connections to servers using self-signed certificates, the FAQ describes disabling SSL peer verification or adding the CA public key to the OpenSSL certificates directory. The documented build process uses Meson and Ninja, with GTK 3 as the default UI build. Settings and bookmarks go under the gftp configuration directory in line with the XDG Base Directory Specification. The client logs the log-window contents to gftp.log and purges the file when the program starts. The project lists 56 language translations and directs bug reports to GitHub issues. Its plan costs nothing.

Serv-U FTP Server provides FTP and FTPS file transfers for organizations, with web and mobile interfaces for viewing, uploading, and downloading files. The FTP Server edition supports IPv4 and IPv6; an edition comparison also lists HTTP. SSL/TLS encrypts transfers. Users can pause or resume multiple and large exchanges, including files larger than 3 GB. Administrators can create users and groups, manage permissions and bandwidth, and review transfer details in a management console. They can set transfer ratios and quotas, limit concurrent sessions, and use IP blocking, reverse DNS options, and anti-hammering controls. Automation can move or delete files after transfer, or disable or reset credentials after a specified number of days. The optional Serv-U Gateway is described as keeping data out of the DMZ and helping meet listed compliance requirements. SolarWinds positions this edition for small businesses and project teams with fewer users and domains on one server. It has no free plan; the listed price is $55 a month, billed annually, and a 14-day trial is available.
