This implements something like a readonly 1MB disk reading as zeroes: nbdkit sh script=- <<'EOF' case "$1" in get_size) echo 1M ;; pread) dd if=/dev/zero count=$3 iflag=count_bytes ;; *) exit 2 ;; esac EOF Use of "-" is analogous to reading passwords from stdin. --- plugins/sh/nbdkit-sh-plugin.pod | 17 ++++++++++ plugins/sh/sh.c

Trying to read a password or inline script from stdin when the -s option was used to connect to our client over stdin is not going to work. It would be nice to fail such usage as soon as possible, by giving plugins a means to decide if it is safe to use stdio during .config. Update nbdkit_read_password and the sh plugin to take advantage of the new entry point. Signed-off-by: Eric Blake

All, I have been looking at zenity to pop up messages on the X screen. Is there another alternative to zenity that I have not found? I need to be able to completely remove the OK button, I cannot find a way in zenity to do this. also It would be nice to have a --timeout 5 option on the command line also. Any suggestions? Jerry

Hi All, I'm currently using/testing samba-4.0.0alpha15. I downloaded the tar ball, followed the Samba4 HOWTO wiki at http://wiki.samba.org/index.php/Samba4/HOWTO and got stuff working pretty well. I have experienced issues with GPOs and such and dynamic dns and so thought I'd try the current version but I cannot now get samba4 to pass quicktest (or any other test). I've tried

This command fails with an incorrect error message: $ nbdkit ssh host=localhost /nosuchfile password=- --run 'qemu-img info $nbd' </dev/null password: nbdkit: error: could not read password from stdin: Inappropriate ioctl for device The error (ENOTTY Inappropriate ioctl for device) is actually a leftover errno from the previous isatty call.

Hi OpenSSH developers, I am using openSSH (now 2.9.9p2, but prob occurs in 2.9p2 also) to execute commands on a remote machine which outputs data to stdout then pipes it to another invocation of ssh which connects back to the first machine in the same way, where it starts a program to read and store the output from the command on the second machine. I am using the "command" option in

Hi, We installed OBSD's ssh package on production and find our batch jobs are hanging on the "ssh" command. The details are included below, for both normal and "hanging" executions. Please let me know if this is a new or existing bug or if you require further info to debug this. The command was executed with the highest debug level (-v -v -v for level 3). This script

I have a few bug reports and some comments after upgrading from SSH 1.2.27 to OpenSSH 2.9p2 at a large university. OpenSSH often fail to return the correct exit status from the remote command if small amounts of data are transfered, SSH version is 2 and ssh is run with no STDIN or with the -n option. Below is an example. Authentication method is hostbased and the file sizes are 1KB, 4KB and 8KB:
