There is a process running in its own network namespace. I would like to telnet to the machine and run a command in this process network namespace, something like that (17543 is the pid of the process with its own network namespace):
# ip netns exec /proc/17543/ns/net ifconfig Cannot open network namespace "/proc/17543/ns/net": No such file or directory # ls /proc/17543/ns/net /proc/17543/ns/net
It complains that the network namespace is not there, but it looks that the file is there. How can I run a command in another process network namespace?
