A File Transfer Consulting interoperability study covering eleven major file transfer products and open source projects has found significant gaps in IPv6 support.
Most of the gaps discovered involved IPv6 compatibility issues with FTP and FTPS, both of which use multiple connections to transfer files. The rest involved incomplete or erroneous implementations of IPv6 features.
“Too many people think IPv6 is all about routers and switches,” said File Transfer Consulting CTO Andy White. “This study demonstrates that managed file transfer users need an IPv6 strategy too.”
The study was timed to coincide with ISOC’s World IPv6 Day and tested basic connectivity, transfers and directory listings with five clients, three web browsers and six servers. Testing included the FTP, FTPS, SFTP (SSH) and HTTP protocols.
Five Software Packages Received Perfect Scores
Server software that completed the compatibility testing with perfect scores included RhinoSoft.com Serv-U, Apache FTPServer and Pure-FTPd. Good scores were also recorded by ProFTPD, CrushFTP and JSCAPE MFT Server.
Client software that completed the compatibility testing with perfect scores included SmartSoft SmartFTP and FileZilla. Good scores were also recorded by FireFTP, Microsoft’s command-line FTP client and JSCAPE AnyClient.
More Software Authors Announce IPv6 Support
White’s study also encouraged the authors of three file transfer software packages to announce support for IPv6 in future versions of their software. After being contacted by File Transfer Consulting, IPv6 support was promised by RhinoSoft.com in their next client release (FTPVoyager 16.0), GlobalSCAPE in their next server release (EFT 6.4) and FileZilla in their next server release (Server 0.9.38).
“It’s exciting to see an entire industry of commercial and open source vendors work together to support IPv6,” said File Transfer Consulting President Jonathan Lampe. “A high level of file transfer interoperability means companies can spend more time on their transmissions strategy and less time on tactical workarounds.”
