Здравствуйте уважаемые читатели !
Сегодня речь пойдет об автоматических бекапах конфигов со всего парка управляемого оборудования.
Rancid вещь однозначно суперская конфигурируется просто работает надежно и быстро !
Из минусов для всего парка полностью пришлось допиливать плагины что бы работало корректно )
так вот например хотим мы бекапить конфиги с cisco тут есть штатный плагин и делать ничего не надо =)
но вот как только захотим бекапить конфиги с D-Link возникает вопрос что править и как запустить ?! тут все придельно просто для тех кто владеет perl’ом + expect это позволяет самому написать плагин или даже целый аналог rancid на коленке )
Одной из полезных опций является контроль за изменениями которые рапортом приходят на почту, а если сеть большая это становиться очень нужной вещью.
Итак пробежимся по установке и настройке .
Установка :
для FreeBSD : cd /usr/ports/net-mgmt/rancid && make && make install
Настройка :
cd /usr/local/etc/rancid/
увидем файлы :
lg.conf.sample rancid.conf.sample
делаем cp rancid.conf.sample rancid.conf
теперь нам нужно его изменить под свои нужды и требования :
vi rancid.conf
у меня выглядит так :
TMPDIR=/tmp; export TMPDIR
BASEDIR=/usr/local/var/rancid; export BASEDIR
PATH=/usr/local/libexec/rancid:/usr/bin:/usr/local/bin:/usr/sbin:/bin:/usr/bin; export PATH
CVSROOT=$BASEDIR/CVS; export CVSROOT
LOGDIR=$BASEDIR/logs; export LOGDIR
RCSSYS=cvs; export RCSSYS
MAX_ROUNDS=1; export MAX_ROUNDS
PAR_COUNT=100; export PAR_COUNT
MAILDOMAIN=»@rancid.mon»; export MAILDOMAIN
LIST_OF_GROUPS=»CiscoDevices D-LinkDevices»
сохраняем переходим к другому важному этапу
Создаем файл где будут храниться пароли ип адреса методы подключения
touch /home/rancid/.cloginrc
Редактируем его вносим наши данные :
vi /home/rancid/.cloginrc
add user 1.1.1.1 userlogin
add user 2.2.2.2 adminlogin
add password 1.1.1.1 OnlyUserpassword
add password 2.2.2.2 adminpassword enablepswd
add password * any password any enable password
add method 1.1.1.1 ssh
add method 2.2.2.2 telnet
add method * telnet
Что значат данные записи :
* значит что для любых хостов
Задать пароль можно один раз в случае если без enable если нужен enable Обязательно задавать ещё и его !
Метод подключения может быть как telnet так и ssh
Дальше нам нужно поправить права :
chmod 600 /home/rancid/.cloginrc
chown rancid:rancid /home/rancid/.cloginrc
дальше удаляем штатный каталог:
rm –r /usr/local/var/rancid
меняем права :
chmod 775 /usr/local/var
притворяемся юзером rancid :
su rancid
создаем папку для rancid:
mkdir /usr/local/var/rancid
запускаем сам rancid что бы создал нужные директории:
rancid-run
запускаем cvs:
/usr/local/bin/rancid-cvs
переходим в директорию нашего демона:
cd /usr/local/var/rancid/
ls
увидем :
CiscoDevices
D-LinkDevices
заходим сначало в папку CiscoDevices:
cd CiscoDevices
vi router.db
пишем туда имена наших хостов вендор и слово up
1.1.1.1:cisco:up
2.2.2.2:cisco:up
сохраняем
теперь нужно настроить пересылку писем на email предварительно надеюсь что почта у вас настроена :
exit из под юзера rancid
vi /etc/aliases
rancid-CiscoDevices: evil@admin.net
rancid-admin-CiscoDevices: evil@admin.net
rancid-D-LinkDevices: evil@admin.net
rancid-admin-D-LinkDevices: evil@admin.net
сохраняем и даем команду newaliases
теперь обратно входим под юзером rancid
su rancid
запускаем сам rancid:
rancid-run
Все хорошо отработал в папке CiscoDevices должны появиться текущее конфиги.
теперь что бы все это работало автоматом создадим таск в кроне :
crontab -e
0 0 * * * /usr/local/bin/rancid-run
что бы он работал раз в сутки
сохраняем
получаем рабочую схему )
кто то спросит как все это дебагать ?) тут все просто rancid в свою папку пишет логи в папку logs там для опеределенной группы есть логи их читаем и все становиться понятно.
Кто то спросит а что если не стартует для группы ?
ну во первых если не стартует для группы возможно есть блокировка искать её в папке /tmp/ для данной групы и удалить если нету процесов ранцида.
Ну а на счет D-Link скажу что есть у меня аж 2 плагина на базе одного найденого в интернете немного кривого для того что бы добавить новый плагин нужно в папке
cd /usr/local/libexec/rancid/
найти файл :
rancid-fe
редактировать его :
vi rancid-fe
так как он перловый думаю проблем у админа не должно возникнуть но я подскажу на всякий случай нас интересует массив
%vendortable
внутри него описываются что мы будем запускать для конкретного вендора :
‘cisco’ => ‘rancid’, как видим для cisco будем запускать скрипт rancid
для D-Link
‘dlink’ => ‘dlrancid’,
для D-Link 36xx
‘d36’ => ‘dl36rancid’,
теперь листинг самих скриптов с правками :
cat dllogin

#
# dllogin — D-Link login
# This script is very much a hack based on the existing code, but it works for us.
#
# Thus far we have tested this on the following D-Link Switch models:
#
# DES-3010F — success (telnet, ssh)
# DES-3052P — success (telnet, ssh, … a little slow)
# DES-3526 — success (telnet, ssh)
# DES-3550 — success (telnet, ssh)
# DES-3250TG — fail (there’s no command to print config)
# DGS-3324SR — success (telnet, ssh)
# DGS-3100 — fail (but probably not too big a job to fix)
#
# Known bugs/issues:
# — line wrap problems cause newlines within config lines at 80 chars wide on
# some models (DES-3010F)
# — ssh can be quite slow on these units and we’ve even had anecdotal evidence
# that the load on the switches can occasionally cause packet loss. We
# generally use telnet for this reason and all is fine.

#
# dllogin — D-Link login
# This script is very much a hack based on the existing code, but it works for us.
#
# Thus far we have tested this on the following D-Link Switch models:
#
# DES-3010F — success (telnet, ssh)
# DES-3052P — success (telnet, ssh, … a little slow)
# DES-3526 — success (telnet, ssh)
# DES-3550 — success (telnet, ssh)
# DES-3250TG — fail (there’s no command to print config)
# DGS-3324SR — success (telnet, ssh)
# DGS-3100 — fail (but probably not too big a job to fix)
#
# Known bugs/issues:
# — line wrap problems cause newlines within config lines at 80 chars wide on
# some models (DES-3010F)
# — ssh can be quite slow on these units and we’ve even had anecdotal evidence
# that the load on the switches can occasionally cause packet loss. We
# generally use telnet for this reason and all is fine.
