hey
i have a problem with a switch case in program and the debugger is messy has hell ( we use normal VI and gdb in our schoool to make it more diffiacult)
any way i have a problom where for some unknown reason the debugger just skips a switch statment as if it wasent even there
the rest of the code works fine
but for some reason that switch statment is just ignored
it uses enums
its all fine and i can see in the debugger that the name has a valid value
i know a lot of things can cause this but any help would be greatly appreciated
i will allso ask, can a memory leak or goingover the border of an array caouse this ?

Hi,
If we want to debug a shell script, then set -vx has to be included in the begining of the script. Just i want to know what purpose -vx is used.
Thanks in advace

Hi i want to debug the C program with GDB debugger. I want to debug the program by line by line. I want to debug program like as we debug the program in Turbo-C using the F8. Can any one help me?
I know i have to use single stepping. But i don't know how to use it. Any help can be appreciated..... (5 Replies)
is there any way you can add a breakpoint in a script so you can stop on it?
i have used -xv in my shebang but the script just runs and i want it to stop at a specific point in the script.
appreciate any help. (1 Reply)
hi all, would you please help me correcting and debugging this script: fx-permiss.sh which accepts a list of users as argument resiting those files permissions:

ipkdb
IPKDB(4) BSD Kernel Interfaces Manual IPKDB(4)NAME
ipkdb -- IP-based kernel debugger
SYNOPSIS
options IPKDB
options IPKDBSECURE
options IPKDBKEY=""IPKDB key for remote debugging""
options IPKDB_NE_PCISLOT=x
DESCRIPTION
ipkdb is a kernel debugger that uses UDP and IP to communicate with a remote debugger (normally gdb(1)).
Since the debugger uses its own driver to talk to the networking hardware, the number of supported network interfaces is a lot less than what
is supported by the kernel. At the time of this writing, there is only support for a NE2000 compatible card in a PCI slot. In order for
ipkdb to find your card, you need to specify the slot the card is in via the options IPKDB_NE_PCISLOT.
To use ipkdb, you have to set up a DHCP server, from which ipkdb can get the IP address for the interface that is used for debugging.
To enter ipkdb, the remote debugger has to send the protocol start packet. E.g., gdb will do this on the command
target ipkdb debuggee IPKDB key for remote debugging
where debuggee is the name of the machine to debug (which must resolve to the IP address of the interface), and the rest of the line corre-
sponds to the definition of IPKDBKEY (see below). For ipkdb to actually see this packet, the interface which is used for debugging has to be
set up to actually receive packets, i.e. it has to be up and running.
To prevent messing around with a secured system, ipkdb normally also checks the security level at which the kernel is running. ipkdb will
only work with security levels less than 1, unless the kernel is configured with options IPKDBSECURE.
In addition, the debugger is forcedly entered on a panic, as well as on initial startup, if you boot the kernel with the -d option (note that
this however is machine dependent). On such a forced enter to ipkdb there is no need for the interface in question to already be up and run-
ning, since ipkdb only needs to send/receive packets via its own driver.
As some form of security against the occasional hacker, ipkdb uses the definition of options IPKDBKEY to compute a checksum on the data in
every packet. The remote debugger has to send this checksum, based on the data it sends and the key, or ipkdb ignores the packet. This is
also used in order to check against data errors on the connection.
SEE ALSO gdb(1), ddb(4), ip(4), udp(4), init(8)HISTORY
ipkdb appeared in NetBSD 1.3 for the first time. Its configuration and setup changed quite a bit in NetBSD 1.5.
BUGS
Since the kernel includes the definition of IPKDBKEY, anyone who can read the kernel can extract it and use it to enter ipkdb.
There is no support for ip6(4).
