Topic: Debug ISDN card?

[Rick Jones]

I'm setting up e-smith for the first time, and got everything working with an external modem. I'm now switching over to ISDN using a card that has been working fine in Windows.

The card is  recognised when I run through config and select ISDN, but it won't connect. The log shows nothing but "Calling site 0.0.0.0." every 20 secs., and "Test access" just reports that it can't connect.

It's an Asuscom P-IN100 card, pretty common - config detects it, and reports the name correctly, so I'm assuming no extra drivers need loading. The card wasn't plugged in when I first installed e-smith though - should that matter?

Is there any way to debug what's going on in more detail, or any hidden configs that should be tweaked?

I'm totally stuck - help!

TIA

Hi,

calling site 0.0.0.0 sounds okay, it's the default route to the outside world (your provider). What does /var/log/messages tell you?

Which seems to suggest it is happy, and trying to call your ISP..

But to be sure: post the relevant bits from your log file (where it shows the ISDN card is detected etc) and the section where it is calling your isp.

Furthermore, search the forum there are many tips on getting it going!

If in doubt whether your card is recognized properly run 'kudzu' (man kudzu gives you the 'whats_this_then?') Any new hardware will be shown. If it finds anything, just say 'yes' to configure.

good luck

which looks pretty much OK to me.

On connecting, it's essentially:

Dec 28 10:32:26 smithy chat[1618]: send (ATZ^M)
Dec 28 10:32:26 smithy chat[1618]: expect (OK)

then

Dec 28 10:33:11 smithy chat[1618]: alarm
Dec 28 10:33:11 smithy chat[1618]: Failed
Dec 28 10:33:11 smithy diald[844]: Connect script failed.

i.e. no response even from ATZ

kudzu doesn't report the card, so it looks like device detection is OK.

Any other ideas?

Thanks a lot

Just an update - got it going at last

FYI - re-ran the config and got different messages, no "chat" stuff, but got ISDN error E001B. Looks like this was down to a faulty cable - maybe the only original problem
Changed the cable and all is well.

Cheers, and HNY

Yep, that means it has no active ISDN wires...

I read that as one possible cause of that error, so it was a good place to start

BUT - still a problem. The throughput to clients is abysmal. Less that 1 kB/sec

I've run an FTP to an Internet site direct on the e-smith server, and the throughput is reasonable (5 kB/s - not good, but might have been the remote server, I haven't checked any other servers yet).

But the equivalent retrieval on a client machine is dog slow. When I had e-smith using a modem there was no problem, the throughput was what I'd expect from a directly connected modem. With ISDN it's just horrible. It's only an old machine, P150 64 MB, but it's been used as an ISDN gateway with Windows and performed fine. I'm switching to Linux for better security and up-time, but I didn't expect this kind of performance hit.

I suspect it's a config issue, but I don't know what I should be looking to change.

Any suggestions?

TIA again
