Operating system name and version: Debian 5.0.8
Version of smsd: 3.1.14
Smsd installed from: sources
Name and model of a modem / phone: Multitech Multimodem
Interface: LAN

I`m running a nagios-server with the setup described as above. Sending sms is working fine until somewhen it stops. I can see the sms hanging in /var/spool/sms/checked/. If i restart the smsd, all the sms will be relaesed.

My config:

Is there an error in my config or whats the problem?

thnx

Your config looks good. I do not know what causes the problem, but probably TCP/IP communication freezes. Previous command was sent successfully, but next command freezes in write() function. In theory you could use tcpdump or wireshark to detect what is happening in the network. But it's not very easy job to do...

You could try with a modem setting send_handshake_select = no which makes the communication little bit different. It may give detailed error message which tells what is really happening. If with this setting communication freezes too, without error messages, the problem is in the TCP/IP side.

Thnx for your reply.

I did some tests and changed the modem-setting: keep_open to yes.
right now it looks like it works. i will be watching this
