Linux/Redhat 8.0 gurus, please help.

I am using Redhat 8.0. Occasionally, my ISP connection (I have a 56k modem) will just die. It doesn't disconnect, I just can't connect to any web sites. This happens to me in Windows too, so I think it's an ISP thing. Anway, when this happens, I have problems using RH8 Network Device Control (NDC) GUI. Technically, my connection is still open. However, when I open NDC to close the connection, I get a message like "can't deactivate connection", something like that. I can close the NDC window, but can't close the connection.So, I'm stuck with this dead connection. The only what I've figured out how to get a new connection is to shutdown and restart! Ahh, Windows all over again! Logging off doesn't work. I know there's a better way.

I've noticed that a LCK..ttyS4 file is created in the /var/lock dir when I have a connection open. When the connection goes dead, this file stays alive. I've tried deleting this file when the connection dies, thinking this might close it, but no luck. Same problem. Any help would be appreciated. Thanks.

- Matt

N.B. I have not used a modem with Linux, so I am probably way off base, but,
long ago, in a distant part of the galaxy, I had a modem that failed just that way. This was in the pre-486 days. The modem used a reed relay to connect to the phone line and would somehow lock in the wrong position. I by-passed it with a soldering iron and used the phone jack as the relay. Shocked

OK, that's not likely happened here, but it could still be a failure of the modem. Do you have a spare you can swap? Do you have any diagnostic messages in
tail /var/log/messages ? Look immediately after the failure.

Yah, I don't think the problem is with the modem. I bought this hardware modem, a rather expensive US Robotics variety, just so I could dial up from my linux box. Previously, I had some type of winmodem that came with my Dell that didn't work under Linux.

I'll have to wait until the problem happens again to identify the diagnostic messages. Until then, it's happy surfing.

You can run a firewall to secure your little network from the www or stuff on that other OS.
