This chapter provides some information about FTP client software that supports TLS secured control connections and has been tested and found to be compatible with the MSS FTP Service. The information in this chapter should not be considered as an endorsement for any specific commercial FTP Client package.
CISL does not normally supply precompiled versions of FTP clients due to the varying security policies at remote sites. Please ask your local system administrator for assistance in installing a compatible FTP client. In particular, you are responsible for complying with any licensing and use restrictions. Additional FTP Client software packages that might work are listed at http://www.ford-hutchinson.com/~fh-1-pfh/ftps-ext.html#client.
The lftp program has superior error recovery and scriptability.
