ioscan

[Tammy Liang]

Is there a similiar command at Linux RedHat
as "ioscan" on HP-UX?
Or is there any command or tool that I can use
on linux to check out what hardware I have on
the system?

Thanks for any help...

[Steven E. Protter]

In the gui there is a point and click hardware checker.

Those that follow me will post a few commands than mimic ioscan functions.

Thanks, Steve. I am mainly looking for the commands that can enter via command line.
We don't have GUI on our linux systems.

Unfortunately there is no all-inclusive ioscan command like HP-UX. You would have to use several other commands to get different information about they system (ie: ifconfig, etc.)
Another option is to use something called "hwbrowser". You can get it from here:
http://rpmfind.net/linux/RPM/ASP/i386/RPMS.9/hwbrowser-0.8-9.noarch.html
I personally have not tried this yet.

I just read your post, in that case forget about the hwbrowser option.

Have you tried:

cdrecord -scanbus

It's good for scanning SCSI bus's

Hello Tammy,

have a look at lshw

http://ezix.sourceforge.net/software/lshw.html

It has an "ioscan-like" output mode.

With lshw I had some problems installing. Refer to,

it works fine ...

/proc is your friend.

everything you want to know on hardware and more is in there, you can simply 'cat' the files to get info.

like 'cat /proc/pci' will give you all info on the pci bus and connected cards/devices, likewise 'cat /proc/cpuinfo' will show you all details on cpu's etc...

Thanks all, especially Martin. I install lshw and it works.
I just have one more question. lshw is opensource free software that can be installed on my linux, right?

Thanks...

[Tammy Liang]

Stuart, There is no cdrecord command in my linux. Is it opensource free software that I can download and install it? I do have "lspci" command on my RH.

[Martin P.J. Zinser]

Hello Tammy,

lshw is licensed under the GPL, the full text can be found in the COPYING file that came with the source code. Essentially it means you can use it for free, but can not claim it as your own and sell it to others.

Thanks, Martin...

I got error message when I try to compile and
install lshw on redhat 7 (Kernel 2.4.18-3)
The error message is below:

[root@akrengcvs1 lshw-A.01.06]# make all
c++ -g -Wall -c usb.cc -o usb.o
usb.cc: In function `string BCDversion (short unsigned int)':
usb.cc:216: `snprintf' undeclared (first use this function)
usb.cc:216: (Each undeclared identifier is reported only once for each
function it appears in.)
make: *** [usb.o] Error 1

I am not familiar with c++ with function.
Am I missing library that include snprintf function?

Thanks for any help..

[Martin P.J. Zinser]

Hello Tammy,

the file mentioned does miss the line

#include

And just for completeness, somebody else figured this in another thread here in the forums.

Greetings, Martin

[Tammy Liang]

Thanks Martin. I found the thread after I post the question...

Closest would be "/sbin/lspci". Do a "man lspci " for options.
