ls.stdout.on('data', function (data) {

That error comes from inside libuv (e.g. the C runtime).

What platform is this? If it's Linux, what does `strace -e
\!mmap,munmap,mprotect,futex node 1.js` print?

If you give me a shell account with gcc and gdb installed I can
probably debug it. My pubkey is here:

sorr, it's a server in intranet. I can fully control it , but I don't have permission to change the mapping of intranet router.

is there any other way to connect? such as a reverse proxy by node ?( but I don't have a static ip server)

had installed node v0.8.7 from git, the same error.

is the glibc version too low ?

when download node-v0.8.7-darwin-x64.tar.gz and exec it warn :

[root@etone46 bin]# ./node

./node: /lib64/libc.so.6: version `GLIBC_2.9' not found (required by ./node)

./node: /lib64/libc.so.6: version `GLIBC_2.7' not found (required by ./node)

[root@etone46 bin]# pwd

I guess we could set up a reverse ssh tunnel or something (provided
you can ssh out) but that's something of a hassle to set up.

Well... 2.5 is quite ancient but it *should* work - when it comes to
making syscalls, libuv mostly bypasses glibc.

since don't find rpm for redhat5, I had install glibc2.9 by git , but install to /usr/local/glibc2.9. I dared not to ln it to default.(is it safe?)
