Щось корисне про IT

Начало тут
После того как мы создали пустой репозиторий на сервере, нужно добавить туда наш проект

git add * && git commit -m "Initial commit" && git push origin master

где,
origin это сервер на котором у нас код… и добавляется он вот так

git remote add origin ssh://git@<hostname>/git/test.git
</hostname>

Возможны ошибки при первом комите:

root@client:app# git push
Password: 
No refs in common and none specified; doing nothing.
Perhaps you should specify a branch such as 'master'.
fatal: The remote end hung up unexpectedly
error: failed to push some refs to 'ssh://root@giserver.com/git/app'

Указываем явно куда пушить

root@gitclient# git push origin master
Password:

remote: error: refusing to update checked out branch: refs/heads/master
remote: error: By default, updating the current branch in a non-bare repository
remote: error: is denied, because it will make the index and work tree inconsistent
remote: error: with what you pushed, and will require 'git reset --hard' to match
remote: error: the work tree to HEAD.
remote: error: 
remote: error: You can set 'receive.denyCurrentBranch' configuration variable to
remote: error: 'ignore' or 'warn' in the remote repository to allow pushing into
remote: error: its current branch; however, this is not recommended unless you
remote: error: arranged to update its work tree to match what you pushed in some
remote: error: other way.
remote: error: 
remote: error: To squelch this message and still keep the default behaviour, set
remote: error: 'receive.denyCurrentBranch' configuration variable to 'refuse'.
To ssh://root@gitserver.com/git/app
 ! [remote rejected] master -> master (branch is currently checked out)
error: failed to push some refs to 'ssh://root@gitserver.com/git/app'

Все равно не поддается на провокацию. Сия ситуация хорошо описана тут http://pete.akeo.ie/2011/07/git-remote-repository.html
Git думает что раз репозиторий пустой, то есть не завершенный первый коммит и не дает простому смертному стать первым. Для этого мы на сервере создадим новую ветку:

root@gitserver : git checkout -b first-commit
Switched to a new branch 'first-commit'
root@gitserver $ git symbolic-ref HEAD refs/heads/first-commit

После этого можем внести изменения в код на клиенте и передать это на сервер

echo "new file" > README
git add README
git commit -m "Added file README"
git push origin master

Чтоб не искать каждый раз заново.
Драйвер для ISDN PRI карты Tormenta2 от украинской компании Nika нужно подкинуть в каталог с оригинальными
dahdi-linux-complete-2****/linux/drivers/dahdi/
И заменить в нем тот драйвер который уже есть tormenta2.rbt
Сам фай можно скачать по это ссылке tormenta2.rbt

Для переноса почты с постороннего почтового провайдера к которому у вас нет доступа по ssh, можно использовать Perl утилиту imapsync
Сначала подготовим пакеты

apt-get install makepasswd rcs perl-doc libio-tee-perl git libmail-imapclient-perl libdigest-md5-file-perl libterm-readkey-perl libfile-copy-recursive-perl build-essential make automake libunicode-string-perl libio-socket-ip-perl ibio-tee-perl

Для пущей убедительности можно поставит необходимые пакеты через CPAN

  perl -MCPAN -e "install Mail::IMAPClient"
  perl -MCPAN -e "install Term::ReadKey"
  perl -MCPAN -e "install IO::Socket::SSL"
  perl -MCPAN -e "install Digest::HMAC_MD5"
  perl -MCPAN -e "install URI::Escape"
  perl -MCPAN -e "install File::Copy::Recursive"
  perl -MCPAN -e "install IO::Tee"
  perl -MCPAN -e "install Unicode::String"
  perl -MCPAN -e "install Data::Uniqid"
  perl -MCPAN -e "install Authen::NTLM"

Клонируем репозиторий imapsync

git clone git://github.com/imapsync/imapsync.git

Запускаем установщик

cd imapsync
mkdir dist
sudo make install

Смотрим, что получилось

# imapsync -v
1.607

Если даная ошибка сыпется в лог с завидным постоянством, то в системе есть конфликт IP-адресов.
Нужно убедится, что у вас нет конфликтов, особенно присмотреться к IPv6 адресам
Как вариант – отключить IPv6
Либо можно понизить логирование самого snmpd демона
В файле /etc/default/snmpd немного поправив строку
