Sebagai contoh kita diperintahkan untuk mengkonfigurasi Router1 supaya bisa diakses via SSH menggunakan port 2009.<\/p>\n

Seperti kita ketahui, SSH menggunakan tcp port 22. Jadi bagaimana kita bisa merubah\/memodifikasi tcp port pada R1 agar bisa terkoneksi via SSH?  Berikut cara mengkonfigurasi SSH hanya di R1. Fitur ini disebut dengan SSH rotary<\/strong><\/span>.<\/p>\n

Pertama-tama kita harus men-generate RSA key pair pada router dengan perintah crypto key generate rsa<\/strong><\/span>. Tapi sebelumnya kita harus mengkonfigurasi hostname<\/strong><\/span> dan domain-name server<\/strong><\/span> pada router tersebut:<\/p>\n

\n
\n
router(config)# hostname R1\nR1(config)# ip domain name cisco.com\nR1(config)# crypto key generate rsa\nThe name for the keys will be: R1.cisco.com\nChoose the size of the key modulus in the range of 360 to 2048 for your\n  General Purpose Keys. Choosing a key modulus greater than 512 may take\n  a few minutes.\nHow many bits in the modulus [512]: 1024\n% Generating 1024 bit RSA keys, keys will be non-exportable...[OK]<\/pre>\n<\/div>\n<\/div>\n
Setelah “RSA key pair” berhasil dibuat, kemudian diperlukan user<\/strong><\/span> dan password<\/strong><\/span> yang harus dikonfigurasi dan meletakkannya pada setting “line VTY” untuk bisa mengakses router tsb, <\/p>\n
\n
\n
R1(config)# username cisco password CISCO\nR1(config)# line vty 0 4\nR1(config-line)# login local<\/pre>\n<\/div>\n<\/div>\n
Sekarang kita sudah bisa mengkonfigurasi router tsb agar bisa menerima koneksi SSH menggunakan port 2009. Hal ini bisa dilakukan dengan perintah ip ssh port<\/strong><\/span> dan rotary group<\/strong><\/span>. Kemudian rotary group dikonfigurasi pada line VTY:<\/p>\n
\n
\n
R1(config)# ip ssh port 2009 rotary 1\nR1(config)# line vty 0 4\nR1(config-line)# rotary 1<\/pre>\n<\/div>\n<\/div>\n
Kita bisa melakukan verifikasi apakah konfigurasi kita sudah benar dan bekerja sesuai keinginan:<\/p>\n
\n
\n
R1#ssh -l cisco -p 2009 2.2.2.1\nPassword:\n\nR1>sh tcp brief\nTCB Local Address Foreign Address (state)\n66CCF71C 2.2.2.1.18922 2.2.2.1.2009 ESTAB\n66CCFC78 2.2.2.1.2009 2.2.2.1.18922 ESTAB<\/span>\n<\/pre>\n<\/div>\n<\/div>\n
Jadi anda sekarang sudah bisa mengkonfigurasi router untuk bisa diakses melalui SSH menggunakan tcp port yang diinginkan.<\/p>\n","protected":false},"excerpt":{"rendered":"
