如何通过SSH将SIGINT发送到远程进程？

Question

我有一个在远程机器上运行的程序,它希望从父代接收SIGINT.该程序需要接收该信号才能正常运行.不幸的是,如果我通过SSH远程运行该进程并发送SIGINT,则ssh进程本身会捕获并中断而不是转发信号.

以下是使用GDB的此行为的示例:

在本地运行:

$ gdb
GNU gdb 6.3.50-20050815 (Apple version gdb-1344) (Fri Jul  3 01:19:56 UTC 2009)
...
This GDB was configured as "x86_64-apple-darwin".
^C
(gdb) Quit
^C
(gdb) Quit
^C
(gdb) Quit

远程运行:

$ ssh foo.bar.com gdb
GNU gdb Red Hat Linux (6.3.0.0-1.159.el4rh)
...
This GDB was configured as "i386-redhat-linux-gnu".
(gdb) ^C
Killed by signal 2.
$

任何人都可以建议一种解决这个问题的方法吗？本地ssh客户端是OpenSSH_5.2p1.
