Official Raspberry DSI 7″ Display not working

…

This appears to be an I2C issue on Pi3 (and possibly earlier, but not Pi4) that causes the touchpanel regulator to lock up.

Adding «dtparam=i2c_vc_baudrate=50000» and «enable_uart=0» to /boot/config.txt seems to fix it for now, and I’ll look at what’s actually going on.

Add udev Rules to the System

sudo vim /etc/udev/rules.d/49-micronucleus.rules

# UDEV Rules for Micronucleus boards including the Digispark.
# This file must be placed at:
#
# /etc/udev/rules.d/49-micronucleus.rules    (preferred location)
#   or
# /lib/udev/rules.d/49-micronucleus.rules    (req'd on some broken systems)
#
# After this file is copied, physically unplug and reconnect the board.
#
SUBSYSTEMS=="usb", ATTRS{idVendor}=="16d0", ATTRS{idProduct}=="0753", MODE:="0666"
KERNEL=="ttyACM*", ATTRS{idVendor}=="16d0", ATTRS{idProduct}=="0753", MODE:="0666", ENV{ID_MM_DEVICE_IGNORE}="1"
#
# If you share your linux system with other users, or just don't like the
# idea of write permission for everybody, you can replace MODE:="0666" with
# OWNER:="yourusername" to create the device owned by you, or with
# GROUP:="somegroupname" and mange access using standard unix groups.

chmod 644 49-micronucleus.rules

Туннель ssh

Дано: сервер локальной сети ourproxy.provider.ru, доступный извне.

Требуется: получить из дома доступ к ресурсам внутри локальной сети, например,
к интранет-серверу 10.10.5.1:80

Решение: выполнить на домашней машине команду, пробрасывающую туннель к
искомому IP-адресу через ourproxy.provider.ru:

ssh -f -N user@ourproxy.provider.ru -L 8080:10.10.5.1:80

Опция -f говорит ssh, что после соединения нужно уйти в background.
Опция -N указывает, что никаких команд выполнять не нужно
Ключ -L означает, что соединения к localhost на порт 8080 нужно перенаправлять
на 80 порт IP-адреса 10.10.5.1

Таким образом, набирая в браузере адрес http://localhost:8080, попадаем на нужный сервер.

how to disable ipv6

Here’s how to disable the protocol on a Red Hat-based system:

# sysctl -w net.ipv6.conf.all.disable_ipv6=1
# sysctl -w net.ipv6.conf.default.disable_ipv6=1

1 2	# sysctl -w net.ipv6.conf.all.disable_ipv6=1 # sysctl -w net.ipv6.conf.default.disable_ipv6=1

To re-enable IPv6, issue the following commands:

# sysctl -w net.ipv6.conf.all.disable_ipv6=0
# sysctl -w net.ipv6.conf.default.disable_ipv6=0

1 2	# sysctl -w net.ipv6.conf.all.disable_ipv6=0 # sysctl -w net.ipv6.conf.default.disable_ipv6=0

Here’s how to disable the protocol on a Debian-based machine.

1. Open a terminal window.

2. Issue the command sudo nano /etc/sysctl.conf

3. Add the following at the bottom of the file:

# net.ipv6.conf.all.disable_ipv6 = 1
# net.ipv6.conf.default.disable_ipv6 = 1
# net.ipv6.conf.lo.disable_ipv6 = 1

# net.ipv6.conf.all.disable_ipv6 = 1

# net.ipv6.conf.default.disable_ipv6 = 1

# net.ipv6.conf.lo.disable_ipv6 = 1

4. Save and close the file.

5. Reboot the machine.

To re-enable IPv6, remove the above lines from /etc/sysctl.conf and reboot the machine.

Add Samba users

Samba uses it’s own password system so users need to be added by root. Note that the users have to exist in /etc/passwd

# smbpasswd -a me
# smbpasswd -a you

1 2	# smbpasswd -a me # smbpasswd -a you

You will be prompted for a password for each of those users.

To list existing Samba users:

# pdbedit -w -L

1	# pdbedit -w -L

Restart the Samba daemon

# /etc/init.d/samba restart

1	# /etc/init.d/samba restart

or, if you are using systemd

# /usr/sbin/service smbd restart

1	# /usr/sbin/service smbd restart

Try to access the shares (as a normal user)

Try locally first, then from another machine on the network which also installed samba client. When prompted, use the password entered when adding the user to Samba.

To access my share:

$ smbclient //ourmachine/me

1	$ smbclient //ourmachine/me

To access your share:

$ smbclient -U you //ourmachine/you

1	$ smbclient -U you //ourmachine/you

To access our shared(!) share:

$ smbclient //ourmachine/ourfiles

1	$ smbclient //ourmachine/ourfiles

#https://wiki.debian.org/SambaServerSimple

mount smb dir from remote machine:

sbin/mount.cifs //192.168.1.99/films /mnt/smbsrv/films -o username=USERNAME(,password=PASSWORD)

1	sbin/mount.cifs //192.168.1.99/films /mnt/smbsrv/films -o username=USERNAME(,password=PASSWORD)

Второй вариант без авторизации.

1. IOS не NPE, т.е. без NPE в назнавнии, т.е., например, вот такой: c2900-universalk9-mz.SPA.151-3.T.bin. У вас — нпе. http://pig.lsd-25.ru/uploads/ios/ (меня разбанили)
2. ИОС не ниже версий: 15.0(1)M4, 15.1(1)T2, 15.1(2)T2, 15.1(3)T. У вас — сами угадаете?
3. Зайти на роутере в привелегированный режим и в режим глобальной конфигурации. Это может быть проблемой. Но это обязательное условие.
4. Ползуясь подсказками (нажимая кнопку «?») написать что-то вроде:
license boot module c2900 technology-package securityk9
license boot module c2900 technology-package uck9
license boot module c2900 technology-package datak9
и после вводка каждой из строк согласиться с EULA.
5. Выйти из режима глобального конфигурирования.
6. Сохранить конфигурацию командой copy system:running-config nvram:startup-config
7. Ответить утвердительно на команду reload.
8. Получить профит.
