Operating system name and version: Debian on PPC Version of smsd: 3.1.11 Smsd installed from: sources Name and model of a modem: Nokia N30 Interface: USB with serial adapter I have very similar behaviour like year ago: http://smstools3.kekekasvi.com/topic.php?id=187I haved did not yet detailed info as it has happened just couple times and I did not yet collect the information from logs and etc.. Could it be the similar problem with PPC platform, or the new verison will help. What is the diffrences? The version 3.1.6 worked for me almoust a year without a problem. brgds Janeks

This morning I got the error again, the behavior is a bit different from that one year ago so I gues that there is some modem specific problem: The behaviour: There are unread messages in the modem, that i saw from led indicators. I restarted smsd - it does not help messages are still in the modem and from log we see that modem is not responding. I restarted the system/server and started smsd - now it works again. smsd.log: trouble.log part: It looks like it could also that the problem is connected with messages that has non latin characters or is started with space symbol / newline symbol (multipart messages?) |

For some reason the serial port is lost. Content of the message should not cause this, but you never know...
As your modem and hardware worked in the past without any errors, probably the changed way of handling the serial port causes this problem. With two settings for a modem you can move back to the way that version 3.1.6 used:
send_delay = 1
send_handshake_select = no
With these settings the string is sent to the modem one character at a time, and between each character there is a one millisecond delay.
However, the "send_handshake_select" is a very common style for handling the serial port and should work without problems.

Those settings did not help. When modem hanged I cannot it even reset with minicoms reset command. But the logs look a bit diffrent: smsd.log: trouble.log I now set the loglevel to 7, let's see. |

But the logs look a bit diffrent:
You just changed the smsd.conf and restarted smsd, without any other actions or issues? Now rtscts does not work... Can you try this with 3.1.6? It might be interesting to see if it works, because there should not be any difference between those versions. But as you told that it was working for a long time, it could be verified now. |

You do not need to uninstall. Extract the package of 3.1.6 to some different directory, compile it in there and run from src directory: ./smsd (do not run "make install"). The uninstall did not proceed, because it wanted "yes" as an answer, not "y". But that's good  , you have still your smsd.conf and /var/spool/sms available... |

O'k I did it. Let's see...
I had to disable send_handshake_select in my config file. As it was unknown for old version.

No it hangs again this morning. Strange - it means that it worked with almoust the same configuration like it was before. But the strange too was that logfiles in /var/log was empty. WIth version 3.1.11 despite I has logfile to another directory it wrote logfiles into /var/log Now I has the logfile specified in configuration file, but it was damaged or something like that - I could not it open and if copied then system reports IO error and I could not get whole file. So I have no logging info.  Could it be a HW problem on my side? Because I have another box, but with the same parameters - should be identical, may be some other version of linux kernel. I now did uninstall and compile the 3.1.6, let's see ...  |

What did you mean, does this kind of an error happen on another hardware too? If you have a disk failure, it may be the reason for the communication problem, because devices are files and files are located on disk... I was running 3.1.12 on PPC without any problems with all handshaking methods: # uname -a Linux macmini 2.6.26-2-powerpc #1 Tue Aug 31 09:21:51 UTC 2010 ppc GNU/Linux # cat /etc/debian_version 5.0.6 The kernel is not the same as yours, but I do not know if it does matter. |

No it not happened on other HW.
I has the same HW that worked well, but it has other problems, so I changed it to the same but new one, that has the same paramaters, but new version of software.

I think that this is an infrequent error which cannot be repeated. The message itself looks correct, but the PDU string contains additional ` characters and they are causing error. The PDU is second part of a message which contains two parts. I assume that you have received the first part without errors.
Probably a problem in communication is causing this failure. You could try a different baudrate, but I'm not sure if it helps because you have had hardware problems in the past too.
If this kind of error happens more often, it could be reasonable to add "PDU checking" to the code. If the PDU looks broken, smsd could try to re-read it and check if it helps. However, I do not yet start coding this feature, because this error is very unusual.
What kind of smsd.conf you have currently? And the hardware, is it the same N30 with USB adapter, or have you replaced something?

How often this error has happened? If this error is more regular, I could try to produce a code for you which tries to check if the error is caused by the communication, or by the modem. This kind of a code will work with check_memory_method 1 which you are using.

It could happen around once per week, but not on regular basis.
The longest run without it was around two weeks, but last was around two days.

Yes, but not exactly the same, modem and USB-serial adapter are the same, but computer parameters are the same and model is the same, but it is not the same box.

You could try if your modem supports check_memory_method = 31. If it is supported, this method will check the length of PDU and if it's incorrect, error is reported to the log. SMS is not handled, and when smsd tries to read messages next time, you can see if this error is repeated. If it is not, you have a communication problem. But if it's repeated, the problem is in the modem.

The unit's HD died couple of weeks ago. So I gues , that probably the problem somehow was connected with HD failures.
And I did not yet restored the system, but I am planning it to do within a week.

I had to re-open this topic... Janeks wrote Apparently I faced with the same (or similar) problem - sporadic hangup of communication smsd with modem. That can be solved only by restarting system (not only smsd).
So I am sending (attached) you the all files of my setup before restart and after.
I hope it could help. If you need some other info - just let me know,
In your system there are two critical problems: 1) The modem or serial interface dies. Smstools cannot do much for this, as the restarting does not help. When this problem next time occurs, you could try if stopping smsd, disconnecting the USB plug, re-connecting it and starting smsd helps. If it helps, it is possible to build a relay which does connecting automatically, but of course it will be just a workaround for the reason which causes the problem. You could monitor this problem using alarmhandler. In the smsd.conf, define: alarmhandler = /usr/local/bin/smsd_alarmhandler.shCreate this script with the following content, and make it executable: #!/bin/bash
LOG="/var/spool/sms/logs/alarm.log"
CONTROLFILE="/var/spool/sms/logs/alarm.control"
# $1 the keyword ALARM
# $2 a date in the format yyyy-mm-dd
# $3 a time in the format hh:mm:ss
# $4 the alarm severity (1 digit number)
# $5 the modem name or SMSD
# $6 the alarm text
echo "$2 $3,$4, $5: $6" >> $LOG
if echo -n "$6" | grep "Modem is not ready to answer commands" >/dev/null; then
if [ ! -f $CONTROLFILE ]
then
DATE=`date +"%Y-%m-%d %T"`
echo "${DATE},1, $5: Alarmhandler created request for reset." >> $LOG
echo "RESET $5 $DATE" > $CONTROLFILE
fi
fi
'bash' Syntax Highlight powered by GeSHi When the permanent error is detected, a file alarm.control is created. You can of course send some alarm using e-mail, but not with a modem because it does not work. As at this time restarting the server is the only way to get the modem working again, you can create another script which is run by cron, and with detects if alarm.control exists with a content RESET*, and run shutdown -r now, if necessary. I think that shutdown -r now can be run in the alarmhandler itself too, but I have not tested it. 2) After you restarted the system, there is a message with incorrect PDU string received (like in the post #13). In this case the PDU is almost correct, but contains several Ctrl-Q` character combinations. As said before, smsd could check and fix this, but it will not resolve the problem. And if some characters are missing, smsd cannot do anything to fix this issue. As you have not disabled handshaking, I have no idea what in your system causes this error, but in any case this error should be fixed... |

It seems, that I should try either another modem and/or serial-usb connector.
Could smsd work with Huawei E1752?
