CLX Version 1.06 released on May 1, 1995
This is the procedure to install the version 1.06 update
of clx software. It requires that you have previously installed
clx version 1.05. We have decided not to release a full version
but rather an update. Please follow the instructions thoroughly.
For a new installation, first unpack the clx_105.tgz file,
follow the instructions in the install.txt file and then continue
with upd_106.tgz.
Login as root and install the new files from the root directory:
# zcat upd_106.tgz | tar xvf -
This will install new files in the directories bin db command doc
and tools in the clx default path /usr/local/clx.
Now start postmaster (if it was not already running):
$ ~postgres/.pmstart
Then login as clx_us and perform the following command sequence:
$ monitor -c "destroy ar_band" clx_db
$ monitor clx_db < ~clx_us/db/ar_band.cd
Help files under ~/box must be deleted. Use the new sysadmin utility
mbx_chk for this:
$ cd ~clx_us/tools
$ mbx_chk
This completes the update of the clx software version 1.06
Further below you will find a list of new features and errors/bugs
which were removed with the new version. (Unfortunately, we cannot
tell you which new bugs have been introduced with the new version :-)
ERROR IN AMATEUR BAND LIMITS
There was a change in the file ~clx_us/db/ar_band.cd.
Firstly, the 40 m band limits were wrong for SSB and CW
and secondly, the file has been extended to make it
possible to either specify a band in meters or frequency
in MHz with the "sh/dx" command.
HELP FILES HAVE MOVED
The user help files have been moved to a new location
due to some problems with the ~clx_us/box directory.
NEW SYMBOLS IN SH/CONF
There are special symbols for different
types of links:
= stands for an active connection
- stands for an active connection
~ connection set up
^ initialisation started
? status unknown
TALK
The talk command has been completely rewritten. It now handles
talk messages more intelligently by routing them to
other nodes in case the user is not connected locally.
Here is the logic behind talk routing:
- You need not specify a user's SSID. clx will automatically
detect this and forward the message to the correct call.
- If the user is not connected locally, the message will be
routed to the appropriate node. clx will substitute a
missing SSID automatically.
- When a user goes from one neighboring node to another,
the talk messages will follow him.
- In case it is not known where the user is connected, you
can force routing to a specific node by specifying the
node callsign with the talk command. You can either use
'>' or '@' as the forwarding symbol. You must not put
blanks between the two calls. This is the correct way
to do it:
talk dj0zy@db0bcc Hello Radio!
- When you receive an external talk, the originating node
will be shown so that you can reply accordingly.
PCxx TELEGRAMS COMPLETELY REWORKED
In version 1.06 of the clx software, the internal handling of
telegrams has been completely reworked. This should eliminate
the problems with ANNOUNCE and TALK which were not reproducible
but ocurred rather often.
As a lot of code has changed regarding the PCxx messages we
would be interested to hear of any unusual observations, even
details. Please let us know about it.
NEW TOOLS
The current Postgres version from time to time corrupts its
index files. To repair them, we have created a tool called
new_idx. CLX must be down when you use this, otherwise some
processes will crash.
Another tool was created to keep clx's database of files
in sync with the entries under ~/box. mbx_chk checks if all
files have corresponding entries in the ml_file table and
if all entries in the table have corresponding files under ~/box.
The remaining files/entries will be deleted. Also files with
a negative size in the database (this is when the files are listed
with "#" as the size symbol) will be deleted.
Changed the check script to detect missing portmapper, postmaster
not running as "postgres" and wrong execute permissions on external
programs.
OTHER DETAILS
You can now use "sh/dx 40" or "sh/dx 7" to list 40 m DX spots.
The "dir" command now shows how many times a message has been
accessed. This figure is displayed next to the message number.
Spurious connect commands showing up on the console which actually
should have gone to the connect in progrss are gone.
When the link connection breaks, messages being forwarded at that
time will now be closed regularly and not left open (which was
indicated by the "#" symbol).
"sh/ann <string>" should now work.
Talk messages are now being routed via passive links if the partner
is connected there.
