gdbserver error (getprotobyname)

[David Jones <davidjones_home@yahoo.com>]

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)
