Description Chris Derichs 2014-02-19 01:54:55 UTC
Description of problem:
When attempting to a server with the Kerberos 5 GSSAPI option check the connection fails with the error:
Connection Failed command-line: line 0: Bad configuration option: protocolkeepalives

Version-Release number of selected component (if applicable):
V. (Qt - 4.8.5)

How reproducible:
Most times. (Sometimes I get a different timeout error)

Steps to Reproduce:
0: Setup two computers in the same Kerberos Realm where single sign-on works for SSH'ing between them without being prompted for credentials. x2goserver should be installed on the other.

1. Start x2goclient
2. Setup a new connection.
3. Fill in the Host, Login name, and check Kerberos 5 (GSSAPI)
4. Save then attempt to connect.
5. See error message.

Actual results:
Error message, connection fails

Expected results:
No error, connection opens.

Additional info:

It looks to me like the problem is in shhprocess.cpp;a=blob;f=sshprocess.cpp;h=07c009f58911a439fed108c7b850d01514cc47cc;hb=HEAD

Lines 34- 38 are a macro related to the error message. It seems if it's not a Mac, -o ProtocolKeepalives=60 is put on the command line for ssh. On Fedora's version of ssh: ssh -o ProtocolKeepAlives=60 hostname fails with the same error but works with ssh -o ServerAliveInterval=60 (the option it puts in case of Mac.)

It seems for Fedora we'd always want  
#define KEEPALIVE_OPTION " -o ServerAliveInterval=60 "
#define KEEPALIVE_OPTION " -o ProtocolKeepAlives=60 "

There's lots of instances of that module building launch strings for ssh using that MACRO but I'm not sure which one is actually the one being used.
