Hi, Don: Thanks very much for your informations.
do you know who from Oracle I can contact so that they can help to fix this ksh93 issue? Thanks, Ervin. -----Original Message----- From: Don Cragun [mailto:dcra...@sonic.net] Sent: 2012年1月6日 16:10 To: Ervin Yan Cc: Korn Shell 93 integration/migration project discussion; Venkatesha M.G.; Steve Sundstrom Subject: Re: [ksh93-integration-discuss] ksh93 hang with rsh on Solaris 11 Hi Ervin, I used to work on utilities, libraries, and standards conformance on Solaris systems before Sun was bought out by Oracle. The problem you described sounded like something that I had seen before when a customer got a restricted shell when they had intended to invoke a remote shell. If that isn't your problem, I can't help. I don't work for Oracle and can't guess any better than you as to when or if your problem will be diagnosed and fixed in a future Solaris release.
