|
||||
|
||||
|
||||
I'm wondering if there exists a utility which would let me determine if
|
||||
an existing term connection is actually alive, and not crashed or hung,
|
||||
as is often the case resulting from a less than perfect phone-line. I
|
||||
was thinking something along the lines of a program which would output
|
||||
"socket is busy" or whatever.
|
||||
|
||||
I've already written a somewhat kludgy script to allow me to do this,
|
||||
but it's very inefficient, and I *know* there has to be a better way.
|
||||
The problem is this: I can test the connection with a simple 'trsh cat
|
||||
testfile'. ('trsh echo ok' results in a broken pipe...) This is not a
|
||||
problem if the connection is alive. The problem is when the connection
|
||||
has dropped, since term is still running on the local machine, and when
|
||||
a trsh or anything term-related is sent through the socket, the command
|
||||
hangs. So, the kludgy part is a background process started when the
|
||||
'trsh cat testfile' is executed, which checks 30 seconds later to see if
|
||||
the command has produced any output. Yuck! Suppose the connection *is*
|
||||
alive, but the remote machine just happened to be lagged during the 30
|
||||
seconds... So you can see it's pretty icky. :( The whole thing is
|
||||
necessary since I want to be able to initialize a term connection if one
|
||||
doesn't already exist whenever a user tries to run a term-specific
|
||||
program. Hmm...I suppose the remote machine could send a character
|
||||
every few minutes, or an empty file, which a program could check the
|
||||
last mod time...
|
||||
|
||||
So anyway, if anybody knows of a program which can quickly and
|
||||
accurately determine if the connection is valid, it would be greatly
|
||||
appreciated.
|
||||
|
||||
|
||||
Side note: Has anybody had problems with tredir in term 119? Mine
|
||||
won't redirect *anything*. I had no problem with term
|
||||
203's tredir... But 203 just wasn't stable enough at
|
||||
the time... ;)
|
||||
|
||||
Side note ii: Tin+term has given me a major headache, trying to compile
|
||||
the darn thing. Mosaic, ftp, telnet, irc have all gone
|
||||
fine with only a few minor changes. So here it is: does
|
||||
anyone have a binary of a working tin using the term
|
||||
port/socket calls? THAT would be greatly appreciated, as
|
||||
I have to read news on the remote machine in text mode....:(
|
||||
|
||||
|
||||
Thanks for reading/skimming/scanning...

Or you can alternately use the klogd daemon in one-shot mode. The end
|
||||
of our rc.bcheck file looks something like this:
|
||||
|
||||
# Dump bootup messages for posterity.
|
||||
/etc/klogd -o -f /usr/adm/boot.msg;
|
||||
|
||||
Note that on an FSSTND compliant system the klogd utility may be found
|
||||
in /usr/sbin and the proper place for the message file may be in
|
||||
/var/adm/boot.msg.

Most linux distributions are already configured to write the boot messages

to /var/adm/syslog.

|

|

While Intel did a port of gcc-2.4.0 to add Pentium optimizations, they did
|
||||
a really poor job of it, violating the front-end/back-end boundary,
|
||||
putting things in the wrong places, writing the code in a sloppy way: the
|
||||
effect is that all of their changes need to be rewritten.
|
||||
|
||||
This is being worked on, but the FSF has a consistent answer when asked
|
||||
questions about when something will be ready: when it's ready.
|
||||
|
||||
The Intel port of 2.4.0 is available in the meantime, though no one is
|
||||
supporting it (at Intel or FSF).

I would like to know how to find the names of the colors that are defined
|

by the XVGA16 generic driver. Is there any way of substituting colors
|

defined by a application so it matches with my generic driver.

Many thanks in advance
