kwdb remote debugging

[prashantm]

I have downloaded the latest version of kwdb
however i m not able to connect to the target system. when i try doing that i get the error
h_error = 1 or h_error = 4.
I have also made the sysname and mac address entry in the kwdbconf file.

I am also not able to start the communication server as a daemon.

Hello,

do you have the latest patch (not seen your problem in it however): PHSS_30601

the man page indicates:
For remote debugging kwdb has to be invoked with a local copy of the kernel file.

have you get locally the remote kernel file?

also inthe man page there is:
Invoking kwdb with /dev/mem or /dev/kmem as an argument will start kwdb for analyzing the local running system.

it implies NOT the remote system.

what is your command line options ?

Hi ,
I have got the copy of vmunix of the target machine on the host.
to invoke kwdb i give the command.
kwdb /dev/kmem.

I need to check whether the latest patches are installed.

[prashantm]

the manual says that "This method requires that a LAN card be installed on the target
system that can be used exclusively by KWDB."

how to ensure that kwdb exclusively uses one of the lancards installed on the system.

Thanks,
prashant.

>I need to check whether the latest patches are installed.

How do you intend to use kwdb to see if you have patches install??

The simplest way is to use swlist on the original system.

[prashantm]

i do not intend to use kwdb to see if the patches are installed. but i said that as in the earlier post i was asked to ensure that the latest patches are installed so that kwdb can run properly

Hello,

i've never used kwdb but if you want to ask a local vmunix file, why do not user adb?

what are you looking for exactly ?

Because adb doesn't have a understandable user interface. :-(
