OpenVMS on x86 is now available for hobbyists! Almost a year after [the official release](/s/blog/OpenVMS_9.2_for_x86_will_be_released_tomorrow.html). This is a part 3 of my getting started guide. Part 2 ended with a working network setup and SSH access. In part 3 we'll do something very exciting, installing the WebUI, a web based management interface for OpenVMS. I'll also share a few smaller tidbits, like how to use the interactive text editor via an `ssh` session and how to use `unzip`.
[You can read all my OpenVMS articles here][2].

In part 3 of the OpenVMS on x86 guide we'll install the [OpenVMS WebUI][6]
and I'll show you a few smaller tidbits, like how to use the interactive
text editor via an `ssh` session and how to use `unzip`. I wanted to also
install a C++ compiler and compile a demo program, but the guide turned out
to be long enough just installing the WebUI and its dependencies.
You need to follow along with my guide, [part 1 covering the installation is here][3]
and [part 2 covering network and ssh is here][4]. I'm going to use SSH to copy
over files so you must have that set up, or be comfortable in getting files
over via FTP, but you have to set that up yourself.
Part of this guide is based on the [official installation documents][7] from VSI.
I'm tailoring them for beginners and hobbyists, but please do check the official
documentation, it's super comprehensive and you can learn a lot from it.
Boot up your OpenVMS virtual machine, if you've followed the earlier parts of
my guide you should have automatic boot setup just as networking and OpenSSH.
Login to your OpenVMS machine via SSH for the rest of this guide.
Here is a screenshot of the WebUI, the result you'll have at the end of this
guide:
![webui][11]
### EVE / EDIT via SSH
I'm covering this part first because we're going to be using SSH for most of
this guide and being able to edit
If you try to use the `EVE` or `EDIT` editor when logged in over SSH, you will
get an error. In the [earlier part ][4] of this guide, I used the line editor
(`EDIT /EDT`) via telnet, then with the `CHANGE` command fired up the screen
editor, but that is cumbersome and fails via SSH.
Lets say you want to create a folder on the main disk for notes, then edit them.
Create the folder:
CREATE /DIRECTORY /VERSION_LIMIT=2 REMY1$DKA0:[NOTES]
SET DEFAULT REMY1$DKA0:[NOTES]
DIR
Output:
%DIRECT-W-NOFILES, no files found
The above command creates a folder on node `REMY1`, disk `DKA0`, named `NOTES`
and changes into it (`SET DEF`).
Remember the file naming scheme is different on OpenVMS:
node$device:[root.][directory]file-name.file-type;version
The `CREATE` command also limits the number of saved versions of a file.
Using the `EDIT` command to edit a file:
EDIT today.txt
Will spit out the following error over SSH:
%TPU-E-NONANSICRT, SYS$INPUT must be supported CRT
Use the following command to have your terminal capabilities detected:
SET TERM/INQUIRE
Then retry the `EDIT` command. You should be in a full screen editor.
`CTRL+Z` saves the file and exits the editor.
To have this done automatically, edit the file `SYSLOGIN.COM` in the `SYS$LOGIN`
folder:
SET DEFAULT SYS$LOGIN
EDIT SYLOGIN.COM
Look for the following DCL symbol assignment:
$ TT_NOINQUIR = "|TW|RT|WT|TK|WS|PY|FT|TN|"
Remote the `|FT` part to have SSH login terminals be `inquired`. Remove the `|TN`
part to have TELNET terminals inquired. Save and exit with `CTRL+Z`.
### Unzip and zip on OpenVMS 9.2 x86
VSI has conveniently included `zip` and `unzip` in the default installation.
However, running them with arguments is a bit tedious. The OpenVMS `RUN`
command does not accept arguments, so running this:
RUN SYS$COMMON:[SYSHLP.UNSUPPORTED.UNZIP]UNZIP.EXE "-V"
will give you the following error message:
$ run SYS$COMMON:[SYSHLP.UNSUPPORTED.UNZIP]UNZIP.exe "-v
%DCL-W-MAXPARM, too many parameters - reenter command with fewer parameters
\"-v\
To use arguments, and to get a shorter incantation, we must define a "foreign command":
unzip :== $SYS$COMMON:[SYSHLP.UNSUPPORTED.UNZIP]UNZIP.EXE
The leading `$` in the equivalence name for the symbol definition is what makes
the `DCL` symbol a foreign command. If the device and directory are omitted,
`SYS$SYSTEM:` is assumed.
After this magic incantation, you can run `unzip "-v"`. Example output:
UnZip 6.00 of 20 April 2009, by Info-ZIP. For more details see: unzip -v.
Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir]
[...]
Compiled with DEC C V7.4-407 for OpenVMS (V8.4-2L1 VAX) on May 27 2021.
You can add the `unzip :==...` line at the bottom of your `SYLOGIN.COM` file in
the `SYS$LOGIN` folder, just like you did with the `TERM/INQ` command in the
previous paragraph to make it available on each login.
The `zip.exe` executable is located in the folder `SYS$COMMON:[SYSHLP.UNSUPPORTED.ZIP]`.
### OpenVMS WebUI installation
The WebUI depends on `Lua` and `CivetWeb`, which we must install and configure
first.
Download both from the [VSI Software portal][5] to your machine (not the VM).
You're looking for the following two files:
- `X86VMS-LUA-V0503-5D-1.ZIP`
- `X86VMS-CIVETWEB-V0114-0D-1.ZIP`
Create a folder in the OpenVMS VM where we'll be storing the installation files:
create /dir DKA0:[SW]
set def DKA0:[SW]
Use `scp` (or for example `FileZilla / WinSCP`) to transfer over the `zip` files.
When using SCP, you can use `/SW/` as the folder, like so:
$ scp X86VMS-CIVETWEB-V0114-0D-1.ZIP system@192.168.1.23:/SW/
system@192.168.1.23's password:
X86VMS-CIVETWEB-V0114-0D-1.ZIP ... 100% 17MB 5.4MB/s 00:03
On the OpenVMS VM you should see the file in the folder we just created:
$ dir
Directory DKA0:[SW]
X86VMS-CIVETWEB-V0114-0D-1.ZIP;1
Total of 1 file.
Repeat this `scp` copy for the Lua file: `X86VMS-LUA-V0503-5D-1.ZIP`.
### Installing the Lua dependency
`Lua` is a dependency of `CivetWeb` so we'll unzip and install `Lua` first.
On your local machine, unzip the file and read the `RELEASE NOTES`. They
contain instructions and information. If this guide is out of date, the
release notes will help you along.
Execute the `unzip` command on OpenVMS as defined earlier:
unzip
Output:
************************************************
* VSI Lua V5.3.5D for VSI OpenVMS x86 VE9.2 *
* and later versions. A copy of the Release *
* Notes is included in this ZIP file. *

The following product will be installed to destination:
VSI X86VMS LUA V5.3-5D DISK$X86SYS:[VMS$COMMON.]
Portion done: 0%...10%...20%..90%...100%
Once it is done, the following output will be displayed:
The following product has been installed:
VSI X86VMS LUA V5.3-5D Layered Product
VSI X86VMS LUA V5.3-5D: Lua for OpenVMS is based on Lua Version 5.3.5
Post-installation tasks are required.
To start the Lua runtime at system boot time, add the following
lines to SYS$MANAGER:SYSTARTUP_VMS.COM:
$ file := SYS$STARTUP:LUA$STARTUP.COM
$ if f$search("''file'") .nes. "" then @'file'
To stop Lua at system shutdown, add the following lines to
SYS$MANAGER:SYSHUTDWN.COM:
$ file := SYS$STARTUP:LUA$SHUTDOWN.COM
$ if f$search("''file'") .nes. "" then @'file'
As we did earlier, use the editor to add those lines to the file as stated:
EDIT SYS$MANAGER:SYSTARTUP_VMS.COM
Almost at the bottom of the file, before the `EXIT` line, insert the following:
$ file := SYS$STARTUP:LUA$STARTUP.COM
$ if f$search("''file'") .nes. "" then @'file'
Save with `CTRL+Z`. If you want to run the `Lua` interpreter, define the
following forgein commands, just as we did above for `zip` and `unzip`:
LUA :== $LUA$ROOT:[BIN]LUA.EXE
LUAC :== $LUA$ROOT:[BIN]LUAC.EXE
You can also manually start it right away with the following command:
@SYS$STARTUP:LUA$STARTUP.COM
#### Installing the CivetWeb dependency
Repeat the unzip and install process for `CivetWeb`:
unzip X86VMS-CIVETWEB-V0114-0D-1.ZIP
Output:
**********************************************
*VSI CivetWeb V1.14-0D-1 for systems running *

Remember to read the `RELEASE NOTES`, they contain more information
than this guide.
Start the installation with the following command:
PRODUCT INSTALL CIVETWEB
Output:

The following product will be installed to destination:
VSI X86VMS CIVETWEB V1.14-0D DISK$X86SYS:[VMS$COMMON.]
Portion done: 0%..90%...100%
When the installation is finished the following output is shown:
The following product has been installed:
VSI X86VMS CIVETWEB V1.14-0D Layered Product
VSI X86VMS CIVETWEB V1.14-0D: CivetWeb for OpenVMS is based on CivetWeb Version 1.14
Post-installation tasks are required.
To start the web server at system boot time, add the following
lines to SYS$MANAGER:SYSTARTUP_VMS.COM:
$ file := SYS$STARTUP:CIVETWEB$STARTUP.COM
$ if f$search("''file'") .nes. "" then @'file'
To stop Civetweb at system shutdown, add the following lines to
SYS$MANAGER:SYSHUTDWN.COM:
$ file := SYS$STARTUP:CIVETWEB$SHUTDOWN.COM
$ if f$search("''file'") .nes. "" then @'file'
Note that default installation uses the SYSTEM account to run the
web server process. It is generally recommended that you run the
web server as using a less privileged account. This may be done
by supplying the account name as a parameter to
civetweb$startup.com or by defining the logical name
civetweb$user as the desired account name. It is also recommended
that you change the ownership of the civetweb$root:[000000...]
directory tree to this account.
Just as earlier, edit the file `SYS$MANAGER:SYSTARTUP_VMS.COM` and add the two
lines just before the `EXIT` line:
$ file := SYS$STARTUP:CIVETWEB$STARTUP.COM
$ if f$search("''file'") .nes. "" then @'file'
I'll not apply the other suggestions regarding the `SYSTEM` user since those
are not really needed for a hobbyist setup where I assume you only expose
the virtual machine in the local trusted network and shut it down when you're
done with it.
You do need to copy some configuration files before starting CivetWeb:
set def civetweb$root:[conf]
set proc/parse_style=extended
copy civetweb^.conf.template civetweb.conf
copy services^.conf.template services.conf
If you receive the following error during the copy command:
%DCL-W-PARMDEL, invalid parameter delimiter - check use of special characters
Make sure you've enabled `ODS-5` filename-parsing with the command `set proc/parse_style=extended`.
Go back to our software folder:
set def DKA0:[SW]
Start CivetWeb manually:
@SYS$STARTUP:CIVETWEB$STARTUP.COM
Check to see if it started correctly:
$ pipe show system | search sys$input civetweb
Output:
00000444 CIVETWEB LEF 6 241 0 00:00:00.14 814 892
You can now go to the following URL in your browser:
http://IP.OF.YOUR.OPENVMS.VM:8082
You should see three files, like the screenshot below:
![index of][8]
Open one of the pages to see that `Lua` integration is working:
![lua civetweb][9]
That was a lot of manual work. I'm used to Linux systems with their package
managers, so the above would be `apt install lua` or `apt install nginx` and
everything would be automatically done, config files, startup services,
sometimes even the firewall. But we're learning a lot.
#### Finally, the WebUI installation
Download the following file from the [software portal][5]:
- `X86VMS-WEBUI-V0401-1-1.ZIP`
Use `scp` or your preferred file transfer tool to copy it over to our
software (`DKA0:[SW]`) folder:
scp X86VMS-WEBUI-V0401-1-1.ZIP system@192.168.1.23:/SW/
Output:
system@192.168.1.23's password:
X86VMS-WEBUI-V0401-1-1.ZIP 100% 35MB 6.1MB/s 00:05
Remember to read the `RELEASE NOTES` locally. Unzip the file:
unzip X86VMS-WEBUI-V0401-1-1.ZIP
Output:
Archive: DKA0:[SW]X86VMS-WEBUI-V0401-1-1.ZIP;1

extracting: VSI-X86VMS-WEBUI-V0401-1-1.PCSI$COMPRESSED_VNC
The release notes indicate that CivetWeb must be installed, but we've taken
care of that, so continue on with the installation:
PRODUCT INSTALL WEBUI
Output:
Performing product kit validation of signed kits ...
%PCSI-I-VSIVALPASSED, validation of DKA0:[SW]VSI-X86VMS-WEBUI-V0401-1-1.PCSI$COMPRESSED;1 succeeded

Once it is finished the following will be shown:
The following product has been installed:
VSI X86VMS WEBUI V4.1-1 Layered Product
VSI X86VMS WEBUI V4.1-1
Post-installation tasks are required.
After installation you need to update civetweb$root:[conf]civetweb.conf and
civetweb$root:[conf]services.conf as described in the release notes. After
making the necessary changes you can restart the web server using the following
command:
$ @SYS$STARTUP:WEBUI$RESTART.COM
There are a few things we need to do to get the WebUI up and running. As
we did with `CivetWeb` and `Lua`, add the WebUI to system startup
in the file `SYS$MANAGER:SYSTARTUP_VMS.COM`. Add the following line
to the bottom, just before `EXIT`:
$ file := @SYS$STARTUP:WEBUI$RESTART.COM
$ if f$search("''file'") .nes. "" then @'file'
To use the WebUI, a user needs special permissions. Even the `SYSTEM` account,
so lets add those permissions and grant them to the `SYSTEM` account:
SET DEFAULT SYS$SYSTEM
MCR AUTHORIZE
Output:
UAF>
The prompt has changed to `UAF>`. Execute the following `UAF` commands:
add/identifier webui_read
Output:
%UAF-I-RDBADDMSG, identifier WEBUI_READ value %X80010002 added to rights database
Then:
add/identifier webui_write
Output:
%UAF-I-RDBADDMSG, identifier WEBUI_WRITE value %X80010003 added to rights database
Give the `SYSTEM` account the permissions:
grant/identifier webui_write SYSTEM
Output:
%UAF-I-GRANTMSG, identifier WEBUI_WRITE granted to SYSTEM
Exit the `UAF>` prompt with the `exit` command.
There are a few `CivetWeb` configuration files that must be updated:
set proc/parse_style=extended
set default civetweb$root:[conf]
copy civetweb^.conf.webui civetweb.conf
copy services^.conf.webui services.conf
copy alert_images^.conf.template alert_images.conf
copy threads^.conf.template threads.conf
copy webui^.conf.template webui.conf
set def DKA0:[SW]
(Re)start the WebUI, this command will also automatically restart `CivetWeb`:
@SYS$STARTUP:WEBUI$RESTART.COM
Output:
%WEBUI-I-SHUTDOWN, shutting down WebUI WebSockets terminal interface
%WEBUI-W-NOTRUN, terminal interface is not running
%CIVETWEB-I-SHUTDOWN, shutting down CivetWeb
%DCL-I-SUPERSEDE, previous value of CIVETWEB$ROOT has been superseded
%DCL-I-SUPERSEDE, previous value of CIVETWEB$SHR has been superseded
%CIVETWEB-I-START, starting Civetweb process
%RUN-S-PROC_ID, identification of created process is 0000044A
%WEBUI-I-START, starting the WebUI WebSockets terminal interface
%RUN-S-PROC_ID, identification of created process is 0000044B
If all went well, open a web browser on your main PC and navigate to the
following URL:
http://IP.OF.YOUR.OPENVMS.VM:8082
You should be greeted with the login page of the WebUI (instead of the CivetWeb
page from earlier):
![webui-login][10]
Login with the `SYSTEM` account and password. If you receive the following error:
Account does not have sufficient permissions
Make sure to setup the permissions as we did earlier.
Here is a screenshot of the WebUI running on my VM:
![webui][11]
Navigating the WebUI is a bit slow, most pages take a second or two to load.
But, don't let that fool you. It is an amazing product that makes managing
an OpenVMS system easier, especially for newer system administrators.
For example, here are two screenshots, one of the disk information screen
and one of users screen, the latter allowing you to add users easily.
![disks][13]
![users][12]
In the next part of the guide I'm going to setup the C++ compiler and compile
some demo code. Once the guide is done I'll post the link here!
