Linuxant modem probs..........

ZeroX5 · 06-30-2003, 02:48 PM

Well, I've just entered the world of linux via Mandrake 9.1 (It sure does take quite a while on dial up). And I must say, it is quite nice, but I cannot get my modem to work. I went to that linuxant.org place and downloaded the drivers needed for my kernel version, it was the rpm files. One I get into KDE, and I double clicked on the RPM files, they started to install, but gave me an error message :"The following packages have bad signatures /home/me/documents/rpm file." It asks me to continue installation, so I do. Then it gives me this message "The signature of the package (rpm name) is not correct."
"GPG: Can't check signature, public key not found."
"pciutils is neede by (rpm)."

This doesn't make too much sense to me, but I did read something similar to this, and the people who replied suggessted a re-download of the files, but I've downloaded them 3 times, so I don't think that's the case. But anyway, help is appreciated. Thank you.

It's not clear what your modem is from your post, so here is a bunch of modem info you can wade through and see if it fits.

# Configuring a pci modem
To configure a pci modem, open an x terminal and su - to the root account:

Code:

[phil@fancypiper phil]$ su -
Password: 
[root@fancypiper root]# cat /proc/pci

Look for your modem in the returned list. Look for something similar to mine:

Code:

  Bus  2, device   2, function  0:
    Communication controller: PCI device 151f:0000 (TOPIC SEMICONDUCTOR Corp) (rev 0).
      IRQ 5.
      I/O at 0xc400 [0xc407].

With this info, I use the setserial command:

Code:

[root@fancypiper root]# setserial /dev/ttyS2 irq 5 port 0xc400 uart 16550a

Then I test the modem with the internet connection wizard and it works. I edit /etc/rc.d/rc.local and enter the setserial command:

Code:

[root@fancypiper root]# pico -w /etc/rc.d/rc.local

My file for an example

Code:

#!/bin/sh
# Redhat /etc/rc.d/rc.local file
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local
# configure modem
setserial /dev/ttyS2 irq 5 port 0xc400 uart 16550a

Now, it remains configured after a reboot.

# Compiling/installing kernel modules
You will need to have installed:
1. The developmental packages (compiler)
2. The kernel source code that matches your running kernel
3. The module source or install code

Check out your system and see what's under the hood and see if you installed the stuff you need to do the job. Open an x terminal and type in this sequence of commands to see what kernel we are running and see if you have the kernel source installed:

Code:

[fancy@tinwhistle phil]$ su -
Password: 
[root@tinwhistle root]# uname -r
2.4.18-3

I am running kernel version 2.4.18-3. Do I have the proper source code?

Code:

[root@tinwhistle root]# cd /usr/src
[root@tinwhistle src]# ls -alc
total 3
drwxr-xr-x    4 root     root          136 Jun 12 14:53 .
drwxr-xr-x   16 root     root          424 Jun  4 12:04 ..
lrwxrwxrwx    1 root     root           14 Jun  4 12:11 linux-2.4 -> linux-2.4.18-3
drwxr-xr-x   16 root     root          584 Jun  4 12:11 linux-2.4.18-3
drwxr-xr-x    7 root     root          168 Jun  4 12:08 redhat
[root@tinwhistle src]#

I do have the same kernel version source code installed in the directory /usr/src/linux-2.4.18-3 and there is a symbolic link named linux-2.4 pointing to it.

If you don't see something similiar to this (but in color), you will need to install the kernel source.

NOTE: I noticed that Red Hat didn't make the symbolic link /usr/src/linux that all of the INSTALL files that I have read mentioned that I need, so I may as well make one now to save editing the files in the source code to install.So, I'll make it just now:

Code:

[root@tinwhistle src]# ln -s linux-2.4.18-3 linux         
[root@tinwhistle src]# ls -alc
total 3
drwxr-xr-x    4 root     root          160 Jun 12 15:46 .
drwxr-xr-x   16 root     root          424 Jun  4 12:04 ..
lrwxrwxrwx    1 root     root           14 Jun 12 15:46 linux -> linux-2.4.18-3
lrwxrwxrwx    1 root     root           14 Jun  4 12:11 linux-2.4 -> linux-2.4.18-3
drwxr-xr-x   16 root     root          584 Jun  4 12:11 linux-2.4.18-3
drwxr-xr-x    7 root     root          168 Jun  4 12:08 redhat
[root@tinwhistle src]#

Ah, there it is, so that's done.

Next, did I install the compiler?

Code:

[root@tinwhistle src]# gcc -v          
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-113)
[root@tinwhistle src]#

Yes, I have a compiler installed.

If you don't have those two things installed, you have to install them first off your install CD.

If they are installed, download the source and happy comiling.

Make sure you carefully read the README and INSTALL files after extracting and before compiling/installing.

I do know for a fact, that it's chipset is conexant, and that it is a winmodem. I'm not quite sure of the brand, but that's all I know about it. It's a 56k v .90. I've also read that I'd have to download a "public key" which I did, but the directions I recieved on how to use it don't see to work on Linux Mandrake for some reason.......

"rpm --import /path/to/pubkey.asc"

I've tried doing that, but it gives me a message stating that it is an unknown command "--import" Ah well, any more help is appreciated. I'll try what you posted, but bear in mind, this is my first time using a Linux OS. So it's a little confusing to me. But I'll give it a shot.

Obi Perrin · 06-30-2003, 04:17 PM

Don't worry about that key thing. I think that Mandrake's newest RPM installer comes with a key checker to ensure the integrity of downloads, but when you download an RPM file by itself, there's no key file with it, therefore nothing to check it against. The dependancy is the only real problem there, I believe. Go into the software installer and search for "pci". pciutils should be one of the results.

I'm quite surprised it wasn't installed by default. After it's installed, try the rpm again.

ZeroX5 · 06-30-2003, 04:20 PM

I tried what Fancypiper told me, but I only got up to the setserial, and it gave me a message "unknown command." So, I'll try what obi says, I'll check back in a few minutes.

ZeroX5 · 06-30-2003, 04:24 PM

By the way, It did find my modem, when I did what fancypiper suggested, but Linux doesn't seem to want to use it. I know it has problems cause of the winmodem stuff, but here's what I got from the modem.

Conexant HSF 56k HSFi Modem (rev 1)
IRQ 11
Master Capable. Latency = 32
Non-prefetchable 32 bit memory at 0xf7000000 [0xf700ffff]
I/O at 0xd400 [oxd407]

Anyway, I forgot to place this on the previous post, so brb, I'm off to try obi's suggestion.

ZeroX5 · 06-30-2003, 04:37 PM

I searched for it, but I could not find the pciutils rpm. I even checked the Install disk, and it is not on there. Since Mandrake consists of more than one CD, could it be possible that it could be on another install disk?!? If so, I'd have to wait another 40 hours........ Great. Well, any help is appreciated.

fancypiper · 06-30-2003, 04:45 PM

Conexant/Rockwell modem HOWTO

Don't use setserial as those instructions were for a real or hardware modem and it won't work for your winmodem.

As root, try the command:

urpmi pciutils

or use the gui software manager to install it. You may need to use a toggle somewhere I seem to remember to see an alpahbetical list of what you can install.

I will try what you suggested, but I seemed to have noticed something right now. I was checking the RPM files on the CD, and on the Mandrake site. I noticed that on the mandrake site, it shows two PCIUTILS RPMs, but on the CD, it shows two other files in it's place.
a pcmcia and another one, But they weren't pcituils........

I found that rather odd........ But anyway, I'll try your suggestion. So brb.

ZeroX5 · 06-30-2003, 05:16 PM

Nope, it didn't find it anywhere. Since this may be the main problem, does anyone know where I can aqcuire the pciutils rpm? It may have to be specific to Mandrake 9.1, so any help is appreciated. Thank you all.

fancypiper · 06-30-2003, 05:41 PM

rpmfind

ZeroX5 · 06-30-2003, 07:48 PM

Well, It looks like Linux Mandrake already had the pciutils installed, cause I downloaded it and tried to install it. Already been installed it said. So, I may have to try to download the files again, but I may just have to go with another modem. I don't want to, but its looking that way. Any more help is appreciated. Thank you.

jsul255227 · 06-30-2003, 09:13 PM

hey zero i am having your exact same prob i have the same kind of modem and everything. I try and install it and it says nokey and i have no idea how to make the file a .asc file because i have to copy and paste it in windows and burn it onto a cd and i loaded in linux but everything i try and do doesnt seem to work. im about to give up and just buy a new modem.

jsul255227 · 06-30-2003, 09:23 PM
