Hi, I've mounted a directory with sshfs:
sshfs -o allow_other user(at)host:/dir /dir
(the (at) is an at-symbol but this forum thinks I'm posting a link which is forbidden...)

I have two files in that directory:
-rw-rw-rw-  1 root root    0 2010-04-28 16:04 file_a
-rw-rw-rw-  1 user user    0 2010-04-28 16:08 file_b
file_a was created by the user root on the remote server and file_b was created by myself after mounting the directory. I can now modify the content of both files but I can only "touch" the file_b. If I touch file_a I get:
touch: setting times of `file_a': Permission denied
If it were a local file everybody would be allowed to touch it because it has the write-right for others. Does anyone know how I could modify the mtime/atime/ctime of a file via sshfs? I don't want to open the file just to set the modification-timestamp.
