發現網路上伺服器的 iLO 地址
有沒有辦法為我的網路上的伺服器發現 iLO 的 IP 地址?我有一個伺服器正在執行,我只能通過 iLO 訪問(沒有其他訪問可用),但我不知道 iLO 正在執行的 IP。
有沒有辦法通過查看流量從網路中發現伺服器的 iLO IP?
該伺服器是執行 HP iLO 的 HP proliant
尋找 ILO 獨有的埠,例如 17988:
nmap -sT -p 17988 iprange
… 例如:nmap -sT -p 17988 --open 192.168.20.0/24
我在以前的工作中使用了這個腳本,它執行得很好,找到了我不知道存在的 ilos。

腳本依賴於 tr sed expr curl 和 nmap

對我來說,這個腳本掃描 /16 需要 29 秒,掃描 /24 需要 11 秒
