20 Örnek İle Netstat Komutu
20 Örnek İle Netstat Komutu
Netstat (network statistics) komut satırından ağ bağlantılarını kontrol etmeye yarayan yardımcı bir programdır. Gelen ve giden bağlantılarla birlikte rotalama tablolarını da görmemizi sağlar. Ağ kartlarına ait istatistiklerle beraber sisteminizdeki açık Portları kontrol etmenize yardımcı olur.
Aşağıda, netstat
komutuna ait 20 farklı örnek gösterilmiştir. netstat -h
komutuyla yardım dokümanını görüntüleyebilirsiniz. CentOS vb. dağıtımlarda net-tools
paketi kullanım dışı bırakıldığından netstat
programını bulamayabilirsiniz. netstat
yerine ss
komutunu da kullanabilirsiniz.
Şimdi, sırayla örneklere bakalım.
