I will test / check that -- but I guess he won't hangup anyway ... bruno Keith Roberts <keith@topaz5.worldonline.co.uk> schrieb am 01.10.2003 12:00:06:

Hmm...

I'm really not sure what to suggest next here...

You have got me stumped with this one Bruno.

Just a few more thoughts.

Does your router have any blocking rules in it?

If you turn IPTables logging off (not the firewall itself)

does your ISDN script work correctly?

Good morning ;-)

I am not block all outgoing traffic from the local box just the dns-requests

All other blocking-rules are in the forward chain ... so if I run win ther won't be a connection established all 3 min. :-) ... default policy (from the

Yes, that's it.

I don't know why... all possible outgoing traffic has been blocked ( for

testing ) but he will not hangup... :-(

That MAY be your problem.

I'm NOT using ISDN, but on my dial-up modem connection, when I hit CTRL-C, to kill wvdial, there are a few packets sent out from my modem, to cleanly terminate the dial-in connection.

Sometimes my dial-in connection will stay live, if I do NOT finish wvdial in the correct manner. eg CTRL-Z instead of CTRL-C.

If you are blocking ALL outgoing packets, this may be why the connection stays open - because the signal to terminate your ISDN connection is not reaching your ISDN service provider.

Here's my 56K modem start sequence:

topaz:/home/keith # wvdial --> WvDial: Internet dialer version 1.42 --> Initializing modem. --> Sending: AT&F0&C1 AT&F0&C1 OK --> Modem initialized. --> Sending: ATDT1470 0808 9933 030 --> Waiting for carrier. ATDT1470 0808 9933 030 CONNECT 38400 --> Carrier detected. Starting PPP immediately. --> Starting pppd at Tue Sep 30 15:20:53 2003 --> pid of pppd: 1255 --> pppd: Using interface ppp0 --> pppd: local IP address 62.64.219.8 --> pppd: remote IP address 213.120.78.69 --> pppd: primary DNS address 212.74.114.193 --> pppd: secondary DNS address 212.74.112.66 --> pppd: Script /etc/ppp/ip-up run successful --> Default route Ok. --> Nameserver (DNS) Ok. --> Connected... Press Ctrl-C to disconnect

[1]+ Stopped wvdial

I've just checked this by hitting CTRL-Z.

My line is still live!

I now have to turn my modem OFF to break the connection.

Now, trying to redial I get:

topaz:/home/keith # wvdial --> WvDial: Internet dialer version 1.42 --> Cannot open /dev/ttyS1: Device or resource busy --> Cannot open /dev/ttyS1: Device or resource busy --> Cannot open /dev/ttyS1: Device or resource busy

Because the wvdial script was not stopped correctly.

Now I kill the bash shell in KDE to remove the device lock, and free up the modem!

HTH - Keith
