Re: Reading multiple channels under the same session

That's probably happening because the python code is creating too many connections at the same time right? But, yes, as you said that looks like somewhere in your code you are forgetting to close the fd of the sockets that already did his job. On Wed, Jan 30, 2019 at 3:29 PM wrote: >

Hi, what about waiting to call ssh_event_remove_fd() until my_channel_close_function() is reached? On Wed, Jan 30, 2019 at 1:48 PM Alberto Garcia wrote: > Hi, > So it is not something specific from Windows that needs to be changed > right? > > Good gob finding the root cause! :applause: > > On

Hi, So it is not something specific from Windows that needs to be changed right? Good gob finding the root cause! :applause: On Wed, Jan 30, 2019 at 1:40 PM wrote: > I have found the issue. And I have an idea how to solve it... But it needs > a bit of a redesign of the whole channel / data

Re: Reading multiple channels under the same session

I have found the issue. And I have an idea how to solve it... But it needs a bit of a redesign of the whole channel / data handling. The problem is that I call  ssh_event_remove_fd() in the callback function, which in turn de-registers this very callback function... This could have worked in a

Re: Reading multiple channels under the same session

I think we face two different problems: One is related to my shaky code only. But the second one could be indeed related to polling and blocking on Windows. Till On 30.01.19 19:18, Alberto Garcia wrote: > We think it is because of a problem with libssh. Andreas maybe you can > bring some light

Andreas, You can use Till example in this thread along with this commands for the ssh client: ssh -vvv -o StrictHostKeyChecking=no -D 0.0.0.0:11223 10.104.1.115 -p -N and to make it crash just run: import requests > import threading > def do_request(): > while 1: > resp =

Re: Reading multiple channels under the same session

We think it is because of a problem with libssh. Andreas maybe you can bring some light to spot the bug? On Wed, Jan 30, 2019, 6:19 AM On 30.01.19 09:27, Andreas Schneider wrote: > > On Friday, January 25, 2019 3:26:10 PM CET g4-l...@tonarchiv.ch wrote: > >> On 24.01.19 22:09, Alberto Garcia

Hi all, You finally find the test code attached. It's a bit complicated, but it can reproduce the issue: 1. Connect to an ssh server which supports direct socket tunnelling: > ./multichannelfw root myserver.com 22 This opens a local listening port at 20021 2. Open two or more simultaneous ssh
