cok fazla sunucu uzerinde calisinca cok fazla alias yazmak zorunda kalabiliyorsunuz ssh baglantilari icin. ssh auth konusunu password olmadan hallediyorsaniz goto makine1, goto solr_server, goto X seklinde ip adresleriyle ugrasmadan baglanti yapmanizi kolaylastiran ufak bir script.

goto.py

#!/usr/bin/python

import os
import sys

try:
    import simplejson as json
except ImportError:
    import json


# {
#    "netscaler": {"ip": "xx.xx.xx.xx", "user": "nsroot"},
#    "vps": {"ip": "xx.xx.xx.xx", "user": "root"}
# }

config_file = "/usr/share/goto-servers.json"

configuration = json.loads(open(config_file).read())

if len(sys.argv) > 1:
    server = sys.argv[1]
else:
    print 'why are you doing that?'
    sys.exit(0)

server_entry = configuration.get(server, None)

if not server_entry:
    print 'no entry found.'
    sys.exit(0)

os.system("ssh %s@%s" % (server_entry.get("user"), server_entry.get("ip")))
