not currently. and i would guess that this would be just as slow, if not slower, given that the clients will have to see and checksum every file that comes across the wire, or just lay them all down blindly while obeying the appropriate excludes. a reinstall via multicast would be just as fast as either - excluding the additional boot cycle overhead. if you believe the issue is server contention, you might try staging the update, doing a rack at a time, for example. if you know that you are just wanting to update one or two files, there are other solutions. cfengine is very commonly used in cases where you have a known set of files that need to be kept up to date automatically in a cluster. for interactive pushing of files, there are also other solutions. pdsh is a popular one, and ganglia has a pretty nice command issue utility (called gexec, iirc), which has a great response time. i'd suggest using one of these tools for onesy-twosy/common-file maintenance, and reserving updateclient/re-installs for larger changes. ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Sisuite-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/sisuite-devel
