Hi! ---- I'm doing some testing with the ssh client OpenSSH on Windows 10 (10.0-19045) but due to firewall restrictions I need to run my experiments from a local port < 1024 (not negotiable). I thought that this was no problem... but ssh |bind()| fails with "address in use" (yes, I checked netstat, no one is there) for any port < 1023. Then I checked $ netstat # and $ netsh int ipv4 show excludedportrange protocol=tcp # and the same for IPv6, noone is using ports. This *feels* like the "restricted port range" (1-1023) on UNIX/Linux, where only "root" can do a |bind()| with a local port < 1023, but this is Windows, and even as "Administrator" this still fails. https://learn.microsoft.com/en-us/troubleshoot/windows-server/networking/default-dynamic-port-range-tcpip-chang talks about a "... well-known ports that are used by services and applications...", but I do not know where to set that (for a Cygwin process). Does anyone know what is going on ? Is there a way around this ? ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) roland.mainz@xxxxxxxxxxx \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 3992797 (;O/ \/ \O;) _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
