This is follow up to my previous message.

In regard subject in question.

Will make story as brief as possible.

Sometime back  in 2013 my TNOS-3.01a1 very often was unresponsive.
TNOS process (PID) was present, tun0 interface with assigned IP
was visible but connection to TNOS wasn't possible at all.

Therefore I crafted set of smart (I hope so!) scripts
in order to keep TNOS up&running and being connectible.

1. In  crontab I put this line:

    */15  *  *  *   *   root  /usr/local/tnos301/tnosrst &> /dev/null

2. This is  tnosrst  script:

#!/bin/sh
#
LOG="/var/log/tnos.log"
TIMESTAMP=`date "+%b %d %X"`
#
/usr/local/tnos301/tnosxpct
sleep 1
#
HANG=`cat /usr/local/tnos301/SP2L.txt | grep -wo "Area:"`
if [ "$HANG" != "Area:" ]; then
     echo "$TIMESTAMP  TNOS is hung-up - restarting..." >> $LOG
     /usr/local/tnos301/startnos
     sleep 1
else
     echo "O.K!" > /usr/local/tnos301/hang.txt
fi


3. This is  tnosxpct  script:

#!/usr/bin/expect
#
spawn /usr/bin/telnet 44.165.2.5
expect ":"
send "sp2l\r"
expect ":"
send "<your_password>\r"
log_file -noappend /usr/local/tnos301/SP2L.txt
expect ">"
sleep .1
send "b\r"
sleep .1
log_file
expect eof


4. This is  startnos  script:

#!/bin/sh
# start NOS on a specific vt 4
BASEDIR=/usr/local
cd $BASEDIR/tnos301
export TERM=konsole

PID=`/bin/pidof -x tnos`
     if [ -n "$PID" ]; then
     kill -9 $PID
     fi
rm -f $BASEDIR/tnos301/spool/mqueue/*.lck
rm -f $BASEDIR/tnos301/spool/mail/*.lck
rm -f $BASEDIR/tnos301/tnos.lock
exec ./tnos -U 0 < /dev/tty4 > /dev/tty4 2>&1 &

That's all, almost all.

Of course scripts have to be modified
to meet local environment requirements.

In order for above to work it is necessary
to install  expect  package, which is available
in most of linux distributions.

The pros: this is nifty and smart solution, IMHO.
The cons: did not noticed so far.

I use similar set of scripts to keep my
dexspider instance up&running  flawlessly.

Although YMMV, Hi!.
