Hi,
I am using gdbserver on a StrongArm board compiled
for arm-linux. On my Linux x86 host I am running
gdb compiled to debug an arm-linux target. Thanks
to Bill Gatliff for helping me out with this.
I can successfully debug a program if I use the serial
port between the host and the target. This is great!
However when I try to use a network connection I get
the following error: (below is a trace of my commands)
(target output)
----------------------------------------------------
# ./arm-linux-gdbserver davesplace:90 hello
Process hello created; pid = 180
getprotobyname: No such file or directory.
Exiting
(host output)
(gdb) target remote tuxscreen:90
Remote debugging using tuxscreen:90
Couldn't establish connection to remote target
Remote communication error: Connection reset by peer.
(gdb)
#
----------------------------------------------------
Has anyone seen this type of error (i.e. getprotobyname)?
I start the gdbserver first as recommended by the GDB documentation.
man getprotobyname shows:
The getprotobyname() function returns a protoent structure for the line from
/etc/protocols that matches the protocol name name.
The /etc/protocols file is present on my StrongArm target.

By the way my StrongArm is a tuxscreen. (see www.tuxscreen.net)
