The VanDyke ClientPack

Security

Authentication methods	All the VanDyke ClientPack applications support password, public-key (RSA, DSA, and Smart Cards* using X.509), Kerberos v5 (via GSSAPI), and keyboard-interactive when connecting to SSH2 servers. vsh supports connections to SSH1 servers using password, public-key, and TIS authentications. * Windows only
Encryption ciphers	The VanDyke ClientPack applications support 3DES, RC4, Blowfish, Twofish, AES-128, AES-192, and AES-256 ciphers when connecting to SSH2 servers. The maximum 2048-bit length of DSA keys under SSH2 provides more secure encryption. For SSH1 servers, DES, 3DES, RC4, and Blowfish are supported.
SFTP protocol support	vcp and vsftp support SFTP through version 6.
FIPS 140-2 (Windows only)	The VanDyke ClientPack for Windows has an administrative option to run in "FIPS Mode". When this option is set, the VanDyke ClientPack applications use a FIPS 140-2 validated cryptographic library and only allow FIPS-approved algorithms.
SSH Agent support	Agent forwarding support allows transparent authentication to multiple linked servers after the first SSH server has authenticated the user.
Port forwarding	vsh allows you to tunnel common TCP/IP protocols (for example, POP3, IMAP4, HTTP, SMTP) to a remote Secure Shell server using a single, secure, multiplexed connection.
Dynamic port forwarding	vsh provides dynamic port forwarding which simplifies how TCP/IP application data is routed through the Secure Shell connection. Instead of configuring port forwarding on a per-application basis in vsh, each application is configured to use a SOCKS server on a local host port. vsh opens a port on the local host and acts as a SOCKS server for any SOCKS-compatible application, even those that use multiple ports, such as FTP.
X11 forwarding	vsh allows you to encrypt X11 Windows sessions to secure remote X applications that are being displayed on the local PC.
Remote execution	Like rsh, vsh can be used to execute commands on a remote system. But unlike rsh, vsh provides secure encrypted communications over a nonsecure network.
SSH1 support	Both SSH1 and SSH2 are supported in vsh, providing the maximum in flexibility when connecting to a range of remote servers.
Create public/private keys	vkeygen is a program that generates public and private keys with options to set the key length (in bits) and passphrase associated with the key pair.
Upload and manage keys	vpka is a public-key assistant program which allows a user with no public key file on the server to upload a public key for use in authentication. vpka can also be used to define parameters for keys and to remove keys from the server.

File transfer (vcp and vsftp)

Create directories	vsftp can be used to create new directories locally and on the remote host.
Rename files	vsftp can be used to rename files locally and on the remote host.
Set permissions	vsftp can be used to change read/write/execute permissions as allowed by logon. It can be used to specify file permissions for uploaded files.
List files	vsftp can be used to display the remote directory listing of either the path or of the current directory if the path is not specified. If the -l flag is set, vsftp displays permission and ownership information. This command, if used with a / (i.e., ls /), lists the roots when connecting to a server such as VShell that allows multiple roots.
Recursive operations	Both vsftp and vcp commands can be recursively applied to all subdirectories in a target directory.
Wildcard matching	Both vsftp and vcp commands can specify a path that contains the wildcard characters * and ?. vsftp will expand these wildcard characters. Multiple wildcard characters are permitted in a path (e.g., "." or ".?"). vsftp also supports file "globbing". The sequence [...] will match any one of the characters enclosed. Within [...], a pair of characters separated by a quotation mark (") matches any character lexically between the two. The backslash can be used to turn off wildcard characters (e.g., \ or \[).
ASCII/Binary file transfers	vsftp supports both ASCII and binary file transfers. Text format files can be sent as raw text rather than in binary format for more compatible transfers of files like HTML and server logs between different operating systems.
Progress indicator	Both vsftp and vcp illustrate the status of a file transfer operation with a text-based progress indicator.
Remote to remote	Copies between two remote hosts can be accomplished using vcp. File sources and destinations may contain a user, host, and port specification to indicate that the file is to be copied to or from that host.

Other Features

Firewall support	The VanDyke ClientPack applications support both SOCKS v4 and v5 for use with SSH1 or SSH2. When using SOCKS v5, optional firewall authentication is supported.
Windows and UNIX support	The VanDyke ClientPack is available for Windows 2000, XP, 2003, and Vista, Red Hat Enterprise v2.1 and v3, Red Hat Linux 7.x, 8.x, and 9.x (Intel x86), Solaris 8 (SPARC), FreeBSD 5.4, 5.3, and 4.8 (Intel x86), HP-UX 11, Mac OS X 10.2, and AIX 5.3.
IPv6	The VanDyke ClientPack applications support the IPv6 standard being implemented across the internet. IPv6 addresses limitations with the current IPv4 standard, such as the limited number of available IPv4 addresses. It also adds many improvements to IPv4 in areas such as routing and network autoconfiguration.
