Section 5.1: Winsock Libraries

>>

Many vendors and shareware authors are releasing Winsock-compatible libraries that implement various Internet protocols like FTP and HTTP. The list below points to as many as I could easily find.

Commercial Products:
    Package: SocketTools
    Vendor: Catalyst Development
    Provides: DNS, finger, gopher, HTTP, FTP, MIME, NNTP, ping, POP, RAS, rexec, rlogin, rsh, SMTP, telnet, time and whois
    Platform(s): Win16, Win32
    Library type: ActiveX, DLL and VBX versions
    Price: $249
    Licensing: Royalty-free
    Commentary: The telnet piece includes VT100 and ANSI terminal emulation. The package also includes components for building a simple browser, such as an HTML display component and image and audio components.

    Package: PowerTCP
    Vendor: Dart Communications
    Provides: Finger, FTP, HTTP, IMAP, MIME, POP, RAS, rexec, rlogin, rsh, SMTP, SNMP, SSL/TLS, telnet, time, TFTP, VT-52 through VT-320 and whois
    Platform(s): Win16, Win32
    Library type: C/C++ (static and DLL), Delphi component, ActiveX, VBX, PowerBuilder
    Price: $200-600 for the base package, $200-1000 per additional component
    Licensing: Varies depending on the type of application.
    Commentary: Many of the items in the "Provides" section above are sold separately from the base PowerTCP package. The base package includes "control"-type libraries. For C++ class libraries and 16-bit components, you must get the "Pro" version of the base package.

    Package: IP*Works!
    Vendor: devSoft
    Provides: Base package: FTP, raw HTTP, raw ICMP, IMAP, LDAP, NNTP, POP, RAS, rexec, rsh, SMTP, SNPP, SNTP and telnet
    PlusPack: finger, HTTP support controls, time, ping, rcp, TFTP, traceroute, and whois
    Commerce Kit: FTP, HTTP, HTTPS, XML
    Platform(s): Win16, Win32
    Library type: C++, VBX, ActiveX, Java, Delphi and C++Builder
    Price: $245-495 depending on the edition, $245 for Commerce Kit
    Licensing: Royalty-free
    Commentary: The library also provides uuencode, Base64 and Quoted Printable binary encoding handling, and mail server address lookup (MX DNS records).
    The PlusPack is free, but only works with the Visual Basic editions.
    Windows CE versions of the base library are available.
    The Commerce Kit apparently does not depend on IP*Works!.

    Package: Visual Internet Toolkit
    Vendor: Distinct
    Provides: Base package: finger, FTP (client and server), HTTP, HTTPS, IMAP, LPR, MIME, NNTP, ping, POP, RAS, rcp, rexec, rlogin, rsh, SLIP and PPP, SOCKS, SMTP, SNMP, telnet, TFTP, VT-220, whois
    Available separately: ONC/RPC (includes XDR)
    Platform(s): Win16, Win32
    Library type: ActiveX, DLL and VBX
    Price: approx. $400 for the main kit, $600 for the RPC kit
    Licensing: Royalty-free?
    Commentary: The ActiveX and 32-bit DLL versions are sold together. VBX and 16-bit DLL versions are sold as separate packages.
    The package also includes uuencoding/uudecoding support, a license manager, and a network sniffer.
    The license manager allows for trialware and "number of running copies" types of licensing.
    The sniffer apparently only works for programs built with the library.
    The ONC/RPC kit appears not to be dependent on the base package, but it is clear that it does not include all of the functionality of the base package. That is, basic networking is available in the RPC package, but not, for example, MIME support. The RPC kit does include the network sniffer and the license manager.

    Package: Ultimate TCP/IP
    Vendor: Dundas Software
    Provides: DNS, FTP, finger, HTTP, IMAP, MIME, NNTP, ping, POP, SMTP, traceroute
    Platform(s): Win32 only
    Library type: C++ class library, ActiveX
    Price: $300 for the ActiveX components, $700 for the C++ version
    Licensing: Royalty-free?
    Commentary: The C++ version inclues the ActiveX components and full source code.

    Package: Tools.h++ Professional
    Vendor: Rogue Wave Software
    Provides: CORBA, FTP, HTTP, POP and SMTP
    Platform(s): Win32, Unix, Linux
    Library type: C++ class library
    Price: $1795 per platform, $3590 for all platforms
    Licensing: Royalty-free?
    Commentary: This package includes all the functionality in Rogue Wave's Tools.h++.
    This package's specialty is cross-platform networking. It includes both functionality to ease communication between disparate platforms, and abstraction layers that allow your program to build on various platforms.

    Package: WinDis32, etc.
    Vendor: PCAUSA
    Provides: various packages for low-level network access (TDI and NDIS layers)
    Platform(s): Windows 9x and Windows NT/2000
    Library type: C library
    Price: $500 for the basic library, $250-1000 for various add-ons and sample kits
    Licensing: Royalty-free

    Provides: Basic network I/O
    Platform(s): Win32 only
