Tru64 UNIX Support


Our Support Value

Tru64 UNIX©, also known as OSF/1 and Digital Unix, has been running in mission critical environments since 1992. While it may be considered an obsolete operating system today, it was widely deployed in its day and remains a stable operating system. Many of its deployments were for long-term use scenarios, such as hard to upgrade industrial controls, military defense systems, logistics and supply chain analytics, and many other such specialties. Given that it's often much cheaper to continue to operate the system rather than replace it, PARSEC's value proposition becomes clear. We offer expert Tru64 support on all DEC Alpha platforms (Alphaservers and Alphastations).

Did you know...

The last major revision of Tru64 UNIX was in 2006

HP no longer supports Tru64 UNIX, and has not released any patches or updates for it since 2010

PARSEC offers the largest curated freeware collection for Tru64 UNIX in the world

We offer updated packages for OpenSSH and Samba on Tru64 UNIX

So, why replace your Tru64 UNIX systems when PARSEC can still support them?

Our technical consultants have Tru64 UNIX experience dating back to before the inception of the Alpha, so no matter what type of Alphas you operate, or what version of Tru64 UNIX you use, we can help. We are the premier provider of Tru64 UNIX support and consulting, with more resources and expertise than probably any other organization on Earth! So, even if your own staff hasn't had to touch the operating system for years, our support staff has up-to-the-minute expertise ready to help.

PARSEC Tru64 UNIX support covers these areas, and much more:


  • OS problem determination
  • AdvFS provisioning and maintenance operations
  • Logical Storage Manager (LSM) operations
  • C2 Security setup and operations
  • Network setup and troubleshooting
  • System builds and automated installation manager configuration
  • Dump analysis for problem determination
  • Custom kernel builds and updates for oddball Alphas (Wildfire, DS25, ES47)
  • Legacy support for Digital UNIX(4.x) and OSF/1 (2.x and 3.x)
  • Cloning and migration
  • New Hardware Delivery (NHD) and patch operations
  • SAN operations and troubleshooting, including boot-from-SAN

We also support a limited number of product overlays for Tru64 UNIX including TruCluster©, NetRain©, and Internet Express©.

Tru64 UNIX Patching Capabilities


Vendors typically stop producing patches for end-of-life operating systems, even for critical issues. If you are faced with this or a similar issue, we can provide key fixes and patches that are not available from HP. These patches can be provided for key services such as Secure Shell, which usually cannot be disabled as a workaround for a critical flaw. We have the expertise to create a limited set of new base packages for Tru64 UNIX, so long as a code-fix is freely available, to cover these issues and provide a real fix for your Tru64 UNIX systems.

Here is a list of issues for which PARSEC can provide internally sourced non-HP replacement patches for critical vulnerabilities. Note that this list covers (more than) all default Tru64 UNIX network services:

  • Secure Shell
  • Network Time Protocol
  • Telnet, rsh, rlogin, and rexec (though customers should really migrate these to SSH, since these are unencrypted services anyway)
  • Talk, ntalk, and writesrv
  • Sendmail
  • SNMP
  • inetd and its internal services

We specifically cannot provide patches for these situations:

  • Kernel patches
  • Most local-only privilege escalation issues
  • HP or 3rd party drivers
  • Tru64 UNIX-specific proprietary software where no open source analog or public source code exists
