Что пишет в логах при установке, запуске и тд ?

Вобщем пробовал ставить отдельно squid, он ругается на отсутствие squidguard. Поставил squidguard и вот что при установке и в логах

Message from cyrus-sasl-2.1.26_12:
You can use sasldb2 for authentication, to add users use:

	saslpasswd2 -c username

If you want to enable SMTP AUTH with the system Sendmail, read
Sendmail.README

NOTE: This port has been compiled with a default pwcheck_method of
      auxprop.  If you want to authenticate your user by /etc/passwd,
      PAM or LDAP, install ports/security/cyrus-sasl2-saslauthd and
      set sasl_pwcheck_method to saslauthd after installing the
      Cyrus-IMAPd 2.X port.  You should also check the
      /usr/local/lib/sasl2/*.conf files for the correct
      pwcheck_method.
      If you want to use GSSAPI mechanism, install
      ports/security/cyrus-sasl2-gssapi.
      If you want to use SRP mechanism, install
      ports/security/cyrus-sasl2-srp.
      If you want to use LDAP auxprop plugin, install
      ports/security/cyrus-sasl2-ldapdb.
Message from squid-3.5.19:
o You can find the configuration files for this package in the
       directory /usr/local/etc/squid.

     o The default cache directory is /var/squid/cache/.
       The default log directory is /var/log/squid/.

       Note:
       You must initialize new cache directories before you can start
       squid.  Do this by running "squid -z" as 'root' or 'squid'.
       If your cache directories are already initialized (e.g. after an
       upgrade of squid) you do not need to initialize them again.

     o When using DiskD storage scheme remember to read documentation:
         http://wiki.squid-cache.org/Features/DiskDaemon
       and alter your kern.ipc defaults in /boot/loader.conf. DiskD will not
       work reliably without this. Last recomendations were:

         kern.ipc.msgmnb=8192
         kern.ipc.msgssz=64
         kern.ipc.msgtql=2048

     o The default configuration will deny everyone but the local host and
       local networks as defined in RFC 1918 for IPv4 and RFCs 4193 and
       4291 for IPv6 access to the proxy service.  Edit the "http_access
       allow/deny" directives in /usr/local/etc/squid/squid.conf
       to suit your needs.

     o If AUTH_SQL option is set, please, don't forget to install one of
       following perl modules depending on database you like:
         databases/p5-DBD-mysql
         databases/p5-DBD-Pg
         databases/p5-DBD-SQLite

     To enable Squid, set squid_enable=yes in either
     /etc/rc.conf, /etc/rc.conf.local or /etc/rc.conf.d/squid
     Please see /usr/local/etc/rc.d/squid for further details.

     Note:
     If you just updated your Squid installation from an earlier version,
     make sure to check your Squid configuration against the 3.4 default
     configuration file /usr/local/etc/squid/squid.conf.sample.

     /usr/local/etc/squid/squid.conf.documented is a fully annotated
     configuration file you can consult for further reference.

     Additionally, you should check your configuration by calling
     'squid -f /path/to/squid.conf -k parse' before starting Squid.

Спасибо огромное за помощь.

Что выдает squid -f /path/to/squid.conf -k parse ?

P.s. Еще команда была, что-то типа squid -z . Чистила кеш вроде (?)

Извеняйте за невежество, команды вводить непосредственно в консоли напрямую?

Можно через SSH, предварительно его разрешив.
Клиент SSH - putty, например.

вобщем перепробовал все.
Результаты такие:
при вводе команды
/root: squid -f /usr/local/etc/squid/squid.conf -k parse

Команда squid -z дает

/root: 2016/07/14 16:27:44 kid1| Creating missing swap directories

И потом так и висит…если нажать на enter появляется строка ожидания команды...

при сохранении стандартных настроек долго ждет и потом
Ошибка при установлении защищённого соединения

Во время загрузки страницы соединение с сервером было сброшено.

Страница, которую вы пытаетесь просмотреть, не может быть отображена, так как достоверность полученных данных не может быть проверена.
Пожалуйста, свяжитесь с владельцами веб-сайта и проинформируйте их об этой проблеме.

ПРичем если галочка об активации squid снята, то служба летает. Как только галочку поставить и нажать сохранить, получим ошибку выше, НО нажав назад в браузере и обновиви страницу, галочка остается, но служба постоянно падает. Я вот думаю может реинициализировать конфиг?

Второе, раньше в сквиде в Integrations были параметры, сейчас их нет
SquidGuard пускаться НЕ хочет.

Доброе.
У вас настроек много на пф ? Вы бы давно уже с нуля 2.3.х подняли и руками бы все перенесли.

Хотелось бы по научному решить вопрос.
Как зайти в конфиг через SSH? Там есть параметр "не стирать конфигурацию при переустановке" Я вот думаю сменить его прям в конфиге и инициализировать. А потом удалить. Чтобы конфигурация старая стерлась.

Пару раз наступал на грабли в 2.0.х-2.2.х - после выполнения Reset to factory defaults в меню консоли в системе оставались огрызки старого конфига.

То есть рекомендации спецов, переставить с нуля?

pigbrother

Если позволяет время - поэкспериментируйте.
Если настроек не много - чистая установка предпочтительнее.

Столкнулся с той же ерундой. Решил так:

Удалил пакет squid. При этом squidGuard вроде можно не трогать.
Удалил папку squid из директории /var:
cd /var
rm -rf squid

Установил пакет Squid.

UPD.: думаю, что удалять и снова устанавливать кальмара не обязательно, достаточно выполнить все что ниже.

Открыл в веб-интерфейсе файл Diagnostics -> Edit File: /usr/local/etc/squid/squid.conf и добавил туда строчки:

squidGuard

url_rewrite_program /usr/local/bin/squidGuard -c /usr/local/etc/squid/squidGuard.conf
url_rewrite_children 5

Затем выполнил команды:
squidGuard -d -C all
chown -R squid:squid /var/db/squidGuard
/usr/local/sbin/squid -k reconfigure

Все. Вручную проверил в веб-интерфейсе, чтобы были запущены сервисы squid и squidGuard, и, естественно, стояли галочки на их запуск.

Информация взята из http://jnotes.ru/squid-content-filter.html а так же лога во время установки пакета squidGuard (прежде чем решил проблему, много раз переустанавливал кальмарочные пакеты разными способами).

Но это при условии, что сохранилась предыдущая конфигурация прокси со всеми настройками для вашей сети. В противном случае нужно будет снова настроить с самого начала прокси. Как это сделать можно посмотреть по ссылке, которую дал чуть выше.
