The /usr/kerberos/bin/rcp has been modified to fix a timing window that could cause the parent kshd to hang. To extract just the /usr/kerberos/bin/rcp file from the rpm run the following command substituting x86_64 for i386 as necessary. The command will ask what name you want the file to be. After the file is extracted save off the original rcp and replace it with this new one. NOTE that a new krb5-workstation rpm will overwrite this new rcp. rpm2cpio krb5-workstation-1.6.1-25.el5.2SL.i386.rpm | cpio -ivum --rename ./usr/kerberos/bin/rcp
