Hi Torsten,

yes you are right! After reading the source of ssh_channel_write() I
totally agree. The buf argument is a const char* so it can't be modified
through ssh_channel_write()...

I'm really suprised that we never had an issue with this... We tested
the code extensively.

Maybe the implementation changed? I wrote it for V0.8.90...

I will check this.

Thanks!
