Smartcard reader ACR122U has no unique serial number

由 浪子不回头ぞ 提交于 2019-12-10 18:34:00
问题 I am using the PCSC driver and the javax.smartcardio library as the wrapper to the driver. I have 3 ACR122U devices plugged into a Linux (debian) system. I have ran udevadm info on the devices and they all have a serial number of 0. I need to identify which reader is which in my class. I can check which topological usb port is used by parsing the /sys/devices folder but I still cant "select" a device in the Java api. Does anyone know a way to modify the PCSC device stack order or something.

Prevent creation of conffiles

由 喜你入骨 提交于 2019-12-10 15:35:49
问题 I'm trying to build a package which has some files under /etc that are not configuration. They are included in the conffiles automatically even if I create an empty package.conffiles in the debian directory. How can I stop dh_installdeb from doing that? 回答1: Originally, this answer suggested providing your own debian/conffiles files only listing actual configuration files to be installed. Apparently that only serves to add more configuration files but won't override the whole conffiles file.

Window 下U盘安装 Debian

1.关于Linux分区问题 linux和Window的分区差别挺大的，初学者不必太纠结与系统分区了。如果想简单点，三个分区可以了 / 保存系统文件， /home 保存用户文件 /swap 交换分区，内存不足的时候会用来置换内存中的文件 或者，五个分区 / 系统内核，系统配置文件等都在此分区 /usr 安装的软件，函数库什么的，改动较少的文件一般在此分区 /var 一些缓存，如：更新时的缓存，这种改动较多的文件一般都在此分区 /home 用户文件，用户配置信息，都在此分区 /swap 交换分区，内存不足的时候会用来置换内存中的文件 分区格式，现在一般都用EXT4吧。 这是我安装完后空间使用情况截图，可以为分区大小的选择提供点参考： 更多问题，查看鸟哥的Linux私房菜：http://vbird.dic.ksu.edu.tw/linux_basic/0210filepermission_3.php -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

转两好文防丢：Debian 版本升级／降级 & Linux 应用程序失去输入焦点问题的解决

由 痴心易碎 提交于 2019-12-10 13:48:19
Debian 版本升级／降级 最近笔记本的 Debian 系统不太正常，总是在程序切换的时候键盘丢失。例如从浏览器切换到 konsole 时，无法输入，在 konsole 中通过创建新标签并在不同标签页中切换后，才能够继续输入... 这个问题很是困扰，联想到最近从 sid （Debian 不稳定发行版）做了升级，难道是升级后出现的 bug？ 题外话：查看磁盘空间，是否有分区已满 实际上，这应该是当系统出现异常后，率先进行检查的。但是由于我的疏忽在Debian降级过程中，才发现 /var 卷已满，当执行 apt-get clean 命令后，释放了 5 GB以上的空间。 所以程序切换键盘丢失，到底是因为 Debian 从不稳定版升级造成的，还是因为 /var 卷已满造成的，已经查无实据。 Debian 混杂版本 所谓 Debian 混杂版本，就是在一个 debian 系统中，安装的软件包不属于同一个发行版(distribution)，有的可能属于 stable（当前代号是 lenny），有的属于 testing （当前代号 squeeze），或者有的软件包属于不稳定版（代号 sid）。 Debian 的 APT 可以设置升级的默认发行版。可以创建一个文件，如： /etc/apt/apt.conf.d/01defaultrelease ，其内容为： APT::Default

debian 7 下的一些错误提示解决办法

由 你。 提交于 2019-12-10 13:48:06
1、修改系统时间 cp /usr/share/zoneinfo/Asia/ShangHai /etc/localtime #时区为亚洲/上海 date 命令查看 2、用惯了vim，在debian下你会发现vi中无法使用delete和backspace键。 原来Debian中自带的vi是vim-tiny，程序本身就不支持Backspace删除功能。 解决办法：重新安装其他版本的vi apt-get update apt-get install -y vim vim-runtime 3、提示-bash: killall: command not found debian下 apt-cache search killall apt-get install psmisc centos下 yum search killall yum install -y psmisc 4、安装libc6 在debian 7 x86_64下安装软件时提示错误： Depends: libc6 (>= 2.14) but 2.13-38+deb7u8 is to be installed E: Unable to correct problems, you have held broken packages. 添加Jessie的源更新就好了 echo "deb ftp://ftp.debian.org
