Wait, wait? What do you mean no payload was sent? I can see in my debug output how following 4096 byte packets get properly sent by writeData(const char* buff, qint64 len). Then when about 2Mb of bytes is sent the attached procedure will show:
QxtSshChannel::writeData ******FKUP!!!! ssh wrote less than it should!!! (171/4096) // 171 is just some value, which shows that the packet fot partially written! All following packets don't get written at all QxtSshChannel::writeData ******FKUP!!!! ssh wrote less than it should!!! (0/4096) QxtSshChannel::writeData ******FKUP!!!! ssh wrote less than it should!!! (0/4096) QxtSshChannel::writeData ******FKUP!!!! ssh wrote less than it should!!! (0/4096) QxtSshChannel::writeData ******FKUP!!!! ssh wrote less than it should!!! (0/4096) . . . Which shows clearly that writeData gets a buffer of 4096, but libssh2_channel_write_ex at some point decides not to write it. So this also answers your question - after ret is 0 I keep writing packets, but I do this because I discovered only today, that writing to ssh channel fails. So I don't really know what else should I do ;-) W dniu 10 sierpnia 2011 19:43 użytkownik Daniel Stenberg <dan...@haxx.se>napisał: > On Wed, 10 Aug 2011, Przemysław Szczygielski wrote: > > I am writing small amounts of data (not more than 4096 bytes) to ssh >> channel, using libssh2_channel_write_ex.
