Date: Sat, 1 Aug 2009 13:46:47 +0800

I tried again with the following steps:

1. machine A with leopard and Cocoa Emacs, ssh login machine B with Ubuntu
2. use machine B to ssh login back to A
3. trigger emacs

I got emacs opening but also the following errors:

and I can do nothing on Emacs but force quit.
Hope this helps.

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Hi,

I've recently moved to MAC OS 10.5 and I compiled Emacs 23 just now, following instructions
under nextstep.

The bug i found is just like this:

1. Cocoa Emacs was opened on machine A with server-start.

Using emacsclient directly under machine A is just fine.

But, if I use another machine B to ssh login A, and then use emacsclient,
it then told me no server can be found. It's wired because i've opend Emacs and its server.

The same operations on Emacs under linux is just fine, so i thought maybe
it's a bug related to Cocoa Emacs.

2. Since Step 1 failed, i tried server-file, too.

I adjusted Emacs server to use tcp and with a server name "bread-emacs".

After then, I use B to loginto A via ssh, and invoke

      ./emacsclient --server-file=/Users/bread/.emacs.d/server/bread-emacs abc

I'll get errors like below:

./emacsclient: connected to remote socket at 255.255.255.255
./emacsclient: connect: Can't assign requested address
./emacsclient: error accessing server file "/Users/bread/.emacs.d/server/bread-emacs"

And here's the contents in ~/.emacs.d/server/bread-emacs

[0:0:0:0:0:0:0:1]:50461 27746
PbZI|X\h]&R~EdtG5n'2q=t^O.:address@hidden;:wrvaQ{4PBxFi.6o@(.5e\C~#c7aT2


I'm not sure if this is a bug, so, if there's more information needed, plz let me know.

Thanks.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/Users/bread/codes/download/emacs/nextstep/Emacs.app/Contents/Resources/etc/DEBUG for instructions.
