Hi,

|I have an SSH server which seems to support only a single
|channel per SSH session. I can connect a first "shell"
|channel just fine; but as soon as I try to connect
|a second channel (shell or files), the entire session
|goes down due to an EOF on the stream.
|
|Would this be a bug of my SSH server not implementing the
|standard correctly?
I think so.
According to RFC4254, instead of closing session,
it should send back the "SSH_MSG_CHANNEL_OPEN_FAILURE" message on such a case.
You know that OpenSSH's sshd allows to open 10 "shell" and "exec"
channels simultaneously, and on such a case it will send back that
message with SSH_OPEN_ADMINISTRATIVELY_PROHIBITED(1).
try{
channel.connect();
}
catch(JSchException e){
if(channel.getExitStatus()==1){
// SSH_OPEN_ADMINISTRATIVELY_PROHIBITED
}
}
|Or is there any possibility to query the server how
|many channels it supports on a single session?
I have never heard such a query.
Sincerely,
