Cara Melakukan Pengecekan Status Koneksi Interface Network di Linux

Kali ini saya ingin sedikit share bagaimana cara nya kita mengetahui status koneksi interface jaringan di server linux yang ada, misal nya saya sudah setting IP namun saya ingin tahu status interface nya sudah tercolok belum kabel nya? atau kabel nya sudah terpasang, namun perangkat lawannya sudah UP atau belum? Intinya mengecek secara fisik status interface network nya.

Untuk mengecek settingan IP kita bisa menggunakan command ifconfig :

# ifconfig
# ifconfig eth0

Namun untuk mengecekan status interface eth0 nya sudah terhubung ke jaringan atau belum secara fisik, kita bisa menggunakan perintah ethtool :

$ ethtool

$ ethtool eth0

Supported ports: [ TP ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Full
        Advertised pause frame use: No
        Advertised auto-negotiation: Yes
        Speed: 1000Mb/s
        Duplex: Full
        Port: Twisted Pair
        PHYAD: 1
        Transceiver: internal
        Auto-negotiation: on
        MDI-X: on
        Supports Wake-on: pumbg
        Wake-on: g
        Current message level: 0x00000001 (1)
        Link detected: yes

Yang dilihat adalah Link detected nya sudah yes, berarti sudah terhubung secara fisik ke jaringan


Semoga bermanfaat untuk pembaca semua.

Memperbaiki error libperl5.22 di Ubuntu 16.04 yang menyebabkan tidak bisa update

Kali ini saya menemukan error di server linux ubuntu 16.04 saya, ketika akan melakukan update linux dari repository, muncul error berikut :

# apt upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 libperl5.22 : Breaks: libperl5.22:i386 (!= 5.22.1-9ubuntu0.2) but 5.22.1-9ubuntu0.5 is installed
 libperl5.22:i386 : Breaks: libperl5.22 (!= 5.22.1-9ubuntu0.5) but 5.22.1-9ubuntu0.2 is installed
 perl : Depends: libperl5.22 (= 5.22.1-9ubuntu0.5) but 5.22.1-9ubuntu0.2 is installed
E: Unmet dependencies. Try using -f.

Disana kita diminta untuk melakukan command apt-get -f install untuk mengatasi masalah diatas :

# apt-get -f install

The following additional packages will be installed:
  libperl5.22

 /var/cache/apt/archives/libperl5.22_5.22.1-9ubuntu0.5_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

Tenyata masih tidak bisa dan malah muncul error yang baru seperti diatas, solusi nya dalah kita move dulu file yang bermasalah nya, yaitu :

trying to overwrite shared '/usr/share/doc/libperl5.22/changelog.Debian.gz

Cara nya adalah jalankan perintah berikut ini :

# mv /usr/share/doc/libperl5.22/changelog.Debian.gz /usr/share/doc/libperl5.22/changelog.Debian.gz.bak

Kemudian coba lagi command apt-get -f install nya :

# apt-get -f install
