Is it spawned by SSH directly or as a result of `qrsh -inherit ...`, while: $ qconf -sconf ... qlogin_command builtin qlogin_daemon builtin rlogin_command builtin rlogin_daemon builtin rsh_command builtin rsh_daemon builtin is set in the old cluster but different in the new one (i.e. pointing to SSH there)? -- Reuti > I cannot determine WHY the behavior is different from RHEL 5 to RHEL 6.
