python pexpect & pxssh with sudo and EOF

由 萝らか妹 提交于 2019-12-23 05:11:42
问题 I make ssh login with this script: import pxssh import pexpect s = pxssh.pxssh() hostname = 'localhost' username = 'py_worker' password = 'nicejob' s.login (hostname, username, password) print "logged in" Then I want to run some program which in some case may require sudo password and in some case may not require. So I want a scrip which could provide sudo password in those cases when required and just run the program if sudo is not asked. I thought this code could handle: s.sendline('sudo

How do I run Valgrind on a program that needs superuser permission?

由 拟墨画扇 提交于 2019-12-23 04:58:06
问题 I'm writing a packet sniffer in C (using libpcap) and I can't use Valgrind to find memory leaks in my program as it must be run with superuser permissions, because, without this, I can't even open the network interface for capture. When I try to run Valgrind with sudo , I got this: $ valgrind sudo ./[exec] ==5211== ==5211== Warning: Can't execute setuid/setgid/setcap executable: /usr/bin/sudo ==5211== Possible workaround: remove --trace-children=yes, if in effect ==5211== valgrind: /usr/bin

Ubuntu的配置及美化

由 不羁岁月 提交于 2019-12-23 03:15:41
xUbuntu安装完成后并不像Windows那样易用与美观，需要自己根据需求进行配置和美化。我安装的是win10 + Ubuntu双系统。 1.系统配置 1.首先我们需要更换国内源，国内有很多镜像源，选择离你最近的。 henhao 完成后在终端更新apt sudo apt-get update sudo apt-get upgrade 2.双系统时区会出现问题，两个系统时间会不一致。 timedatectl set-local-rtc 1 --adjust-system-clock 3.安装基本软件。 谷歌浏览器，搜狗输入法，网易云音乐，都支持linux，分别在其官网可以下载。 还需安装vim文本编辑器 sudo apt-get install vim qq,tim等软件并没有linux版本，不过可以使用wine安装，只是使用体验并不是很好。 2.美化 Ubuntu从18.04开始使用Gnome,所以需要先安装此工具 sudo apt install gnome-tweak-tool 安装完成后到Ubuntu软件中的附加组件安装 user themes 和 dash to dock 下载好的压缩包解压后放到相应的目录中。 Grub 引导界面的美化 下载Grub美化包，解压文件，放到 ：/boot/grub/themes 目录下 使用终端修改grub文件 sudo gedit

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 10 years ago . how do you set it so that sudo doesn't prompt you for your password every time? i have root. 回答1: Use the NOPASSWD option in /etc/sudoers. This is generally a bad idea, though, as any user who gets access to an account that run commands through sudo without a password may be able to compromise the system. Also,

AWS EMR bootstrap action as sudo

问题 I need to update /etc/hosts for all instances in my EMR cluster (EMR AMI 4.3). The whole script is nothing more than: #!/bin/bash echo -e 'ip1 uri1' >> /etc/hosts echo -e 'ip2 uri2' >> /etc/hosts ... This script needs to run as sudo or it fails. From here: https://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-plan-bootstrap.html#bootstrapUses Bootstrap actions execute as the Hadoop user by default. You can execute a bootstrap action with root privileges by using sudo . Great news... but
