Сертификат для Exchange

By kadmin | Exchange, WEB, Windows Server | No Comments

Теперь совсем некрасиво не воспользоваться возможностью получения бесплатного доверенного сертификата SSL для почтового сервера Exchange., уже заботливо написан скрипт для получения, установки и создания задачи для автоматического обновления SSL сертификата задолго до окончания его срока.

.\wacs.exe --target manual --host mail.domain.ru,autodiscover.domain.ru --certificatestore My --installation iis,script --installationsiteid 1 --script "./Scripts/ImportExchange.ps1" --scriptparameters "'{CertThumbprint}' 'IIS,SMTP,IMAP' 1 '{CacheFile}' '{CachePassword}' '{CertFriendlyName}'"

Ищем удалённые ящики в одной или во всех базах

$mailboxes = Get-mailboxdatabase | Get-MailboxStatistics | where-object { $_.DisconnectDate -ne $null}

$mailboxes = Get-MailboxStatistics -Database mcs | where-object { $_.DisconnectDate -ne $null -and $_.DisplayName -like "Иванов Иван*"}

Создаём временных пользователей (без однофамильцев)

foreach ($mailbox in $mailboxes){ New-ADUser -Path "ou=test,dc=domain,dc=com" -Name $mailbox.displayname.split(" ")[0] -enable $True -accountPassword (ConvertTo-SecureString -AsPlainText "!!qwerty2018" -Force)}

Подключаем ящики к пользователям

foreach ($mailbox in $mailboxes) {Connect-Mailbox -Database $mailbox.database -Identity $mailbox -User $mailbox.displayname.split(" ")[0]}

1	foreach ($mailbox in $mailboxes) {Connect-Mailbox -Database $mailbox.database -Identity $mailbox -User $mailbox.displayname.split(" ")[0]}

Сохраняем в PST

foreach ($mailbox in $mailboxes) {

Exchange DAG

By kadmin | Exchange, Kadmin, Windows Server | No Comments

В одной конторе) жил сервер Exchange 2013 и был запасной сервер в запасной сети в запасном сайте, связаны сервера были между собой через VPN. Решил я добавить mailbox дабы получить успокоительный DAG. Бессмысленно было создавать отдельную сеть для репликации и добавлять вторые сетевые карты в виртуальные машины находящиеся на разных хостах в разных местах, соединенных через одну VPN. Я добавил DAG без IP адреса:

И все было было бы хорошо но при добавлении сервера в DAG я получал следующие: Read More

Squid, Kerberos и SquidGuard

By kadmin | AD, CentOS, Kadmin, SQUID | No Comments

После включения Centos в домен, (use_fully_qualified_names = True) или до… поставим Squid c авторизацией в AD и парсер блэклистов SquidGuard.

yum install squid squidGuard

1	yum install squid squidGuard

Запускаем Squid:

systemctl enable squid
systemctl start squid

1 2	systemctl enable squid systemctl start squid

Проверяем ходит ли браузер в Инет через прокси.
Смотрим в tail -f /var/log/squid/access.log

Для аутентификации пользователей через AD создадим пользователя proxy и кейтаб для него proxy.keytab на контроллере домена:

ktpass -princ HTTP/proxy.domain.ru@DOMAIN.RU -mapuser squid -pass паролик -ptype KRB5_NT_SRV_HST -out proxy.keytab

Successfully mapped HTTP/proxy.domain.ru to squid.

ktpass -princ HTTP/proxy.domain.ru@DOMAIN.RU -mapuser squid -pass паролик -ptype KRB5_NT_SRV_HST -out proxy.keytab

Successfully mapped HTTP/proxy.domain.ru to squid.

Копируем proxy.keytab на proxy.domian.ru, chown squid. proxy.keytab, и прописываем в /etc/sysconfig/squid

KRB5_KTNAME=/etc/proxy.keytab
export KRB5_KTNAME

1 2	KRB5_KTNAME=/etc/proxy.keytab export KRB5_KTNAME

Проверка:

kinit -V -k -t /etc/proxy.keytab HTTP/proxy.domain.ru@DOMAIN.RU

1	kinit -V -k -t /etc/proxy.keytab HTTP/proxy.domain.ru@DOMAIN.RU

Добавляем в /etc/squid/squid.conf

auth_param negotiate program /usr/lib64/squid/negotiate_kerberos_auth -r -s HTTP/proxy.domain.ru@DOMAIN.RU
auth_param negotiate children 300 startup=20 idle=10

http_access deny CONNECT !SSL_ports

http_access deny manager

http_access deny to_localhost

http_access deny !localnet

http_access allow auth

http_access deny all

http_port 3128

cache_mem 3000 MB

maximum_object_size_in_memory 4 MB

cache_mgr info@domain.ru

url_rewrite_program /usr/bin/squidGuard -c /etc/squid/squidGuard.conf

Или просто после INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS в /etc/squid/squid.conf добавляем:

acl auth proxy_auth REQUIRED
http_access allow auth

1 2	acl auth proxy_auth REQUIRED http_access allow auth

Проверяем ходит ли браузер в Инет через прокси с аутентификацией.
Смотрим в tail -f /var/log/squid/cache.log

Редактируем /etc/squid/squidGuard.conf

dbhome /etc/squid/blacklists
logdir /var/log/squidGuard
src lan {
        ip              192.168.0.0/16

В конец /etc/squid/squid.conf

url_rewrite_program /usr/bin/squidGuard -c /etc/squid/squidGuard.conf

1	url_rewrite_program /usr/bin/squidGuard -c /etc/squid/squidGuard.conf

И вот такой скрипт для обновления списков SquidGuard ./listupdate:

cd /etc/squid
rm -rf shallalist.tar.gz
wget http://www.shallalist.de/Downloads/shallalist.tar.gz
tar zxf shallalist.tar.gz
yes | cp -RT BL/ blacklists/
chown squid. -R /etc/squid/
squidGuard -C all
chown squid. -R /etc/squid/
service squid restart

cd /etc/squid

rm -rf shallalist.tar.gz

wget http://www.shallalist.de/Downloads/shallalist.tar.gz

tar zxf shallalist.tar.gz

yes | cp -RT BL/ blacklists/

chown squid. -R /etc/squid/

squidGuard -C all

chown squid. -R /etc/squid/

service squid restart

mkdir /etc/squid/BL
chmod +x /etc/squid/listupdate
и crontab -e обновляем каждый день:

30 0 * * * /etc/squid/listupdate

1	30 0 * * * /etc/squid/listupdate

Запускаем:

./listupdate

1	./listupdate

Или без обновления:

chown squid. -R /etc/squid/ &amp;&amp; squidGuard -C all &amp;&amp; chown squid. -R /etc/squid/ &amp;&amp; service squid restart

1	chown squid. -R /etc/squid/ && squidGuard -C all && chown squid. -R /etc/squid/ && service squid restart

Смотрим в tail -f /var/log/squidGuard/squidGuard.log

Синхронизация времени с контроллером

yum install ntp ntpdate

ln -s /usr/share/zoneinfo/Europe/Moscow /etc/localtime

ntpdate -bs 192.168.123.222
ntpdate 192.168.123.222
service ntpd star

yum install ntp ntpdate

rm -rf /etc/localtime

ln -s /usr/share/zoneinfo/Europe/Moscow /etc/localtime

service ntpd stop

ntpdate 192.168.123.222

ntpdate -bs 192.168.123.222

ntpdate 192.168.123.222

service ntpd star

Вот и все, теперь хотелось бы добавить фильтрацию для отдельных пользователей но при добавлении

src googusers {
user admin badadmin
}

src googusers {

user admin badadmin

}
