send signals to process in through channel #221
Description
Hello an thanks for that library
Is it possible in ssh2-python to the current process running in a channel, like it is in the ssh specs ?
for instance on paramiko you basically can't but you can always hack it with the private API:
from paramiko import Message
from paramiko.common import cMSG_CHANNEL_REQUEST
from signal import Signals
# trigger termination with a standard openssh packet (since v7.6) but using the private API of paramiko because it doesn't natively implements it
# spec: https://www.ietf.org/rfc/rfc4254.txt
message = Message()
message.add_byte(cMSG_CHANNEL_REQUEST)
message.add_int(channel.remote_chanid)
message.add_string("signal")
message.add_boolean(False)
message.add_string(Signals.SIGTERM.name[3:])
client.get_transport()._send_user_message(message)It would greatly help me since i'm using SIGTERM and SIGINT signals to stop the continuously running processes i'm starting over ssh

Thanks for the interest.
The function libssh2 uses for passing ad-hoc signals is not implemented yet - would be
ssh2.Channel.signal.Added channel.signal function for sending signals to an open channel.…
