|Assume that my remote Linux box uses UTF-8 encoding and my local Windows
|box uses Cp1252 default encoding.
|I'd like to open a ChannelShell session on the remote, end set some
|default environment variables including Unicode Characters.
...
|which uses the local Platform default encoding to encode the Strings, so
|I cannot pass my UTF-8 Strings onto the Wire.
|It's not a very big problem because most SSH daemons have disabled
|environment setting support anyways,
|but still it's not nice that this feature is missing.
Accroding to RFC4254[1],
6.4. Environment Variable Passing
Environment variables may be passed to the shell/command to be
started later. Uncontrolled setting of environment variables in a
privileged process can be a security hazard. It is recommended that
implementations either maintain a list of allowable variable names or
only set environment variables after the server process has dropped
sufficient privileges.
byte SSH_MSG_CHANNEL_REQUEST
uint32 recipient channel
string "env"
boolean want reply
string variable name
string variable value
it seems that we are allowed to send 'name' and 'value' in our
favorite encoding.
So, I have changed the internal and you can also set name and value
in byte[] in the next release. I mean that,
java.util.Hashtable env=new java.util.Hashtable();
env.put(name.getBytes(yourEncoding),
value.getBytes(yourEncoding));
((ChannelShell)channel).setEnv(env);
channel.connect();
Sincerely,
