Thanks Edward Its oscar 4.0 on Redhat 9.0. The fix we tried was looking something like this,
export C3_RSH='ssh -x' cexec uptime. Actually this warning appears only when executing mpi programs in oscartst login,but as for as root login is considerd we are not facing this problem.One more thing is,we are not connected to public NTP servers instead we are using a local one.can this be a reason for the warning. thanks in advance ullas ----- Original Message ----- From: "Michael Edwards" <[EMAIL PROTECTED]> To: "ullas ckm" <[EMAIL PROTECTED]> Subject: Re: [Oscar-users] warning during execution of mpi programs why?(no ssh problem).
