This sends output to STDERR, POLLIN) above may seem silly, but the idea is to wait for a hang-hup event (for the reading end of the pipe on stdout to be closed). POLLHUP as a requested mask is ignored. POLLHUP is only meaningfull as a returned event (to tell that the writing end has been closed). Invoke tcpdump over ssh piping to STDOUT, for importation to a local Wireshark via STDIN. · 13 comments. Reverse-engineering Broadcom wireless chipsets.

Like most commands on Linux, SSH can be used with input/output redirection via | (Unix Pipe). SSH can be used with this pipeline too. The basic concept here is understanding how the Unix pipeline works. When you understand the way pipes work, you can get seriously creative. This article covers what Author: Derrik Diener, med-assistant.info ssh host 'something > file' Here's a contrived demonstration of a way to handle redirection, pipes and quotes: ssh host date -d yesterday \| awk "'{print $1}'" \> 'file" "with\ med-assistant.info' The pipe and redirection are escaped rather than being contained in an overall outer set of quotes, reducing the need to escape one level of quotes. I also added the same ssh-command "unwrapped" to the script which prints all output as expected. Finally I switched on ssh's verbose mode which resulted in error-log-entries. But that's not an option as I dont't want ssh's bebug messages in my log. Am I missing something? Is there same strange stdout,err handling ssh is doing I'm not aware of? Note that out out is printed on stdout and err on stderr. Question: How to do this remotely via ssh? More precisely, how to run. ssh host 'echo 1 | tee /dev/stderr SOME_MAGIC_HERE' st. again out/err pops up on stdout/stderr (for an appropriate bash magic SOME_MAGIC_HERE). Clearly, the following works. I have a process running on an embedded system (linux). its STDOUT/STDERR is the console which is on a serial port. I would like to redirect its ouputs (standard and error) to that of an SSH session. I have read you can do similar operations with GDB, but I don't know how you would redirect to the SSH session's STDOUT/STDERR instead of to a file.

Try this: ssh -p XXYY -l root $remoteIP "sed '/keyword/d' /etc/fileA > /etc/fileA_temp". Using pipe and ssh to connect commands between different unix hosts. Many Linux / unix commands let you to connect local STDOUT to. I'd like to access the command line via SSH over network. something similar to this - redirect application to netcat, but over SSH for security.
