12.1.3 Queues Some resource managers allow queues (or classes) to be defined and then associated with a subset of available compute resources. With such systems, such as Loadleveler or PBSPro, these queue to node mappings are automatically detected. On resource managers which do not provide this service, Moab provides alternative mechanisms for enabling this feature. 12.1.3.1 TORQUE/OpenPBS

最近機器每天都會有無數的SSH失敗嘗試記錄，有些無聊的人一直不停的掃描，這些人真夠無聊的，沒事吃飽了撐著，老找些軟體在那裏窮舉掃描,所以大家第一要記的設定一個好的夠複雜的密碼。 怎麼樣防,如果要一條一條將這些IP阻止顯然治標不治本，還好有DenyHosts軟體來代替我們手搞定他。 DenyHosts是Python語言寫的一個程式，它會分析sshd的日誌文件，當發現重複的攻擊時就會記錄IP到/etc/hosts.deny文件，從而達到自動 Black IP的功能。 DenyHosts官方網站為：http://denyhosts.sourceforge.net 以下是裝設記錄（以CentOS 5.1, DenyHosts 2.6 為例） 裝設 #wget http://nchc.dl.sourceforge.net/s ... ython2.4.noarch.rpm #
