#nmap
Nmap 3.75 Usage: nmap [Scan Type(s)] [Options] <host or net list>
Some Common Scan Types ('*' options require root privileges)
* -sS TCP SYN stealth port scan (default if privileged (root))
-sT TCP connect() port scan (default for unprivileged users)
* -sU UDP port scan
-sP ping scan (Find any reachable machines)
* -sF,-sX,-sN Stealth FIN, Xmas, or Null scan (experts only)
-sV Version scan probes open ports determining service & app names/versions
-sR RPC scan (use with other scan types)
Some Common Options (none are required, most can be combined):
...
* -Ddecoy_host1,decoy2[,...] Hide scan using many decoys
-6 scans via IPv6 rather than IPv4
-T <Paranoid|Sneaky|Polite|Normal|Aggressive|Insane> General timing policy
-n/-R Never do DNS resolution/Always resolve [default: sometimes resolve]
-oN/-oX/-oG <logfile> Output normal/XML/grepable scan logs to <logfile>
-iL <inputfile> Get targets from file; Use '-' for stdin
* -S <your_IP>/-e <devicename> Specify source address or network interface
--interactive Go into interactive mode (then press h for help)
Example: nmap -v -sS -O www.my.com 192.168.0.0/16 '192.88-90.*.*'

|
В журнал автоматически попадают все команды, данные в любом терминале системы.
Для того чтобы убедиться, что журнал на текущем терминале ведётся, и команды записываются, дайте команду w. В поле WHAT, соответствующем текущему терминалу, должна быть указана программа script.
Команды, при наборе которых были допущены синтаксические ошибки, выводятся перечёркнутым текстом:
$ l s-l bash: l: command not found |
Если код завершения команды равен нулю, команда была выполнена без ошибок. Команды, код завершения которых отличен от нуля, выделяются цветом.
$ test 5 -lt 4 |
Команды, ход выполнения которых был прерван пользователем, выделяются цветом.
$ find / -name abc find: /home/devi-orig/.gnome2: Keine Berechtigung find: /home/devi-orig/.gnome2_private: Keine Berechtigung find: /home/devi-orig/.nautilus/metafiles: Keine Berechtigung find: /home/devi-orig/.metacity: Keine Berechtigung find: /home/devi-orig/.inkscape: Keine Berechtigung ^C |
Команды, выполненные с привилегиями суперпользователя, выделяются слева красной чертой.
# id uid=0(root) gid=0(root) Gruppen=0(root) |
Изменения, внесённые в текстовый файл с помощью редактора, запоминаются и показываются в журнале в формате ed. Строки, начинающиеся символом "<", удалены, а строки, начинающиеся символом ">" -- добавлены.
$ vi ~/.bashrc
|
Для того чтобы изменить файл в соответствии с показанными в диффшоте изменениями, можно воспользоваться командой patch. Нужно скопировать изменения, запустить программу patch, указав в качестве её аргумента файл, к которому применяются изменения, и всавить скопированный текст:
$ patch ~/.bashrc |
Для того чтобы получить краткую справочную информацию о команде, нужно подвести к ней мышь. Во всплывающей подсказке появится краткое описание команды.
Если справочная информация о команде есть, команда выделяется голубым фоном, например: vi. Если справочная информация отсутствует, команда выделяется розовым фоном, например: notepad.exe. Справочная информация может отсутствовать в том случае, если (1) команда введена неверно; (2) если распознавание команды LiLaLo выполнено неверно; (3) если информация о команде неизвестна LiLaLo. Последнее возможно для редких команд.
Большие, в особенности многострочные, всплывающие подсказки лучше всего показываются браузерами KDE Konqueror, Apple Safari и Microsoft Internet Explorer. В браузерах Mozilla и Firefox они отображаются не полностью, а вместо перевода строки выводится специальный символ.
Время ввода команды, показанное в журнале, соответствует времени начала ввода командной строки, которое равно тому моменту, когда на терминале появилось приглашение интерпретатора
Имя терминала, на котором была введена команда, показано в специальном блоке. Этот блок показывается только в том случае, если терминал текущей команды отличается от терминала предыдущей.
Вывод не интересующих вас в настоящий момент элементов журнала, таких как время, имя терминала и других, можно отключить. Для этого нужно воспользоваться формой управления журналом вверху страницы.
Небольшие комментарии к командам можно вставлять прямо из командной строки. Комментарий вводится прямо в командную строку, после символов #^ или #v. Символы ^ и v показывают направление выбора команды, к которой относится комментарий: ^ - к предыдущей, v - к следующей. Например, если в командной строке было введено:
$ whoami
user
$ #^ Интересно, кто я?в журнале это будет выглядеть так:
$ whoami
user
| Интересно, кто я? |
Если комментарий содержит несколько строк, его можно вставить в журнал следующим образом:
$ whoami
user
$ cat > /dev/null #^ Интересно, кто я?
Программа whoami выводит имя пользователя, под которым мы зарегистрировались в системе. - Она не может ответить на вопрос о нашем назначении в этом мире.В журнале это будет выглядеть так:
$ whoami user
|
Комментарии, не относящиеся непосредственно ни к какой из команд, добавляются точно таким же способом, только вместо симолов #^ или #v нужно использовать символы #=
1
2
3
4
Группы команд, выполненных на разных терминалах, разделяются специальной линией.
Под этой линией в правом углу показано имя терминала, на котором выполнялись команды.
Для того чтобы посмотреть команды только одного сенса,
нужно щёкнуть по этому названию.
LiLaLo (L3) расшифровывается как Live Lab Log.
Программа разработана для повышения эффективности обучения Unix/Linux-системам.
