Hi,
With OpenSSH 8.9p1 (and earlier) and scp server-side on Linux 5.13,
one gets a very confusing error message when the target directory ends
with / and *does not exist*:
% scp /etc/issue localhost:/usr/foobar/
scp: /usr/foobar/: Is a directory
stracing shows:
[pid 32671] stat("/usr/foobar/", 0x7fff4aaa5fd0) = -1 ENOENT (No such file or directory)
[pid 32671] openat(AT_FDCWD, "/usr/foobar/", O_WRONLY|O_CREAT, 0644) = -1 EISDIR (Is a directory)
scp.c does rougly:
exists = stat(np, &stb) == 0;
/* ... stuff elided ... */
if ((ofd = open(np, O_WRONLY|O_CREAT, mode)) == -1) {
bad: run_err("%s: %s", np, strerror(errno));
continue;
}
open(2) says:
EISDIR pathname refers to a directory and the access requested involved
writing (that is, O_WRONLY or O_RDWR is set).
Apparently, on OpenBSD it prints "No such file or directory" instead.
I wonder if adding
if (errno == EISDIR)
errno = ENOENT;
would be a suitable override, or perhaps you have a better idea.
But printing something is directory when it isn't is confusing. :)
cu,
