|
Hi, I am experimenting a very extrange behaivor with my ppp modem connection.
I was searching on forums, google and mailing lists about this strange problems, but find no good answer.
My kernel is a gentoo-source 2.4.20-r3 (the problem persist either witn 2.4.20-r1 and r2) with pppd 2.4.1 and the LTmodem driver is ltmodem-8.26_alpha9-r1.
Some Config files:
wvdial.conf
| Code: |
[Modem0]
Modem = /dev/ttySLT0
Baud = 56600
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Auto DNS = off
ISDN = 0
Modem Type = Analog Modem
[Dialer info]
Init9 = AT&V
[Dialer noreconect]
Auto Reconnect = off
[Dialer via_networks]
Stupid Mode = on
Idle Seconds = 0
Dial Attempts = 0
Phone = 51234567
Username = xxxxxxx
Password = xxxxx
Inherits = Modem0

/etc/ppp/options
| Code: |

/etc/ppp/peers/via_networks

connect '/usr/bin/wvdial --chat via_networks'

# will have to create these files by hand then.
# Also, the FWSCRIPT feature will not work.

Now, the problem is: The modem dials to my ISP quite well, and pppd do the authentication without a problem. As you can see, I am setting the modem to do a PERSIST connection 24*7. Aparently everything goes right, until, it hangs the connection with an average timing of 230.0 minutes. Here are some logs:
| Code: |
Apr 24 21:54:21 [pppd] Connect time 240.1 minutes.
Apr 24 22:35:28 [pppd] Connect time 40.5 minutes.
Apr 25 09:58:25 [pppd] Connect time 6.5 minutes.
Apr 25 15:52:16 [pppd] Connect time 26.7 minutes.
Apr 25 16:16:54 [pppd] Connect time -30.0 minutes.
Apr 25 18:57:31 [pppd] Connect time 160.0 minutes.

Now, the outup of the running process shows this line:
| Code: |
/usr/sbin/pppd lock debug persist holdoff 2 defaultroute modem crtscts asyncmap 00000000 mru 1500 mtu 1500 user xxxxxx remotename via_networks /dev/modem 56600 ipparam ppp0 linkname ppp0 call via_networks noauth
|
This box was running RedCrap 7.3 with the same hardware and the Persist configuration used to work well without a problem.
The people using this server machine, are very angry about the situation because the phone bill will be huge.!
Please Help me !
