A Monthly Newsletter – June 2010

One strength of the SecureCRT® and SecureFX® clients is their ability to allow you to efficiently create, manage, and use many host connections.  This month we offer a set of tips to help you take advantage of the many capabilities you have when working with multiple sessions.  Next, we show you how to configure the VShell® FTPS server to use third-party certificates for SSL authentication.  Development for SecureCRT and SecureFX continues, with testers needed for new pre-beta capabilities.  A quick update on SecureCRT for Mac OS: alpha testing continues to go well – so look for a beta version in the next few months.  This month's featured forum post is about server hopping, for those situations when direct host connections won't do the trick.

1. Tips for Managing Multiple Connections

One of the biggest strengths of SecureCRT and SecureFX has been the ability to manage and use multiple session connections, for example when you need to connect to the same set of sessions
every day, or many times each day.  The following is a selection of tips and tricks for managing multiple connections and acting on multiple sessions, with links to the VanDyke Software website support section and online forums.

2. VShell FTPS Tip: Creating, Signing, and Using Certificates

The VShell for FTPS server uses an authentication system based on SSL encryption, where systems are validated by their certificates, whether self-signed or validated by a certificate authority (CA).  The tip explains how to generate a certificate, submit it to a CA for signing, and add it to the VShell server system for use.

Call for Testers: SecureCRT, SecureFX Transfer Options

VanDyke Software Development is looking for users to test new capabilities in pre-beta releases of SecureCRT and SecureFX. SecureCRT adds a binary transfer mode and a logging option, while two SecureFX features give the user more control over file transfers.


    • "Send Binary" file transfer
      The Send Binary mode allows sending data such as an .EXE file to a remote machine even if it doesn't support the Xmodem, Ymodem, or Zmodem protocols.
    • Generate unique log file name for same session
      A new log file can be automatically created and used for logging, which avoids being prompted for a log file name when a session is cloned, connected more than once, or connected via SFTP.


    •  Choose between queued and parallel transfers
      File transfers may now be done in parallel as well as in serial mode, with control over the number of parallel transfers allowed.
    • "Throttle" FTP bandwidth
      Limit the amount of bandwidth that transfers consume, to avoid using all available bandwidth.

If you would like to test and provide feedback on any of these new features, please send e-mail to

4. Heard on the Forums: Hop Connections

Forum users regularly search the VanDyke Software forums for information on using port forwarding to "hop" server connections. Server hopping means connecting from client A through servers B and C to server D, where D may be a machine that A can't connect to directly.  A variety of tunneling capabilities can be used depending on the network configuration, including remote forwarding, dynamic forwarding, and forwarding a proxy.
