i'm using a source built version 5.1p1 under SLES 10 testing tunnel device forwarding. Everything is working perfectly, but for reasons unknown to me, I receive this msg whenever i bring up the connection: emperor:~ # /opt/openssh-5.1p1/bin/ssh -S ./sshvpn-ctl -M -f -w 0:0 my-ssh-server-name true SIOCSIFNETMASK: Cannot assign requested address With -v it shows up in this snip: debug1: sys_tun_open: tun0 mode 1 fd 4 debug1: channel 0: new [tun] debug1: channel 1: new [client-session] debug1: setting up multiplex master socket debug1: Entering interactive session. debug1: Sending command: true SIOCSIFNETMASK: Cannot assign requested address debug1: client_input_channel_req: channel 1 rtype exit-status reply 0 debug1: channel 1: free: client-session, nchannels 2 ssh happily connects to the remote end (running Debian's 4.3p2 openssh) and I can ifconfig the tunnel up and add routes and everything works as it should. Anyone know what's causing the SIOCSIFNETMASK error?
