Backup Free Books General Monitoring Networking News Package Mgmt Security Server Bandwidth in computer networking refers to the data rate supported by a network connection or interface. One most commonly expresses bandwidth in terms of bits per second (bps). The term comes from the field of electrical engineering, where bandwidth represents the total distance or range between the highest and lowest signals on the communication channel (band). Bandwidth represents the capacity of the connection. The greater the capacity, the more likely that greater performance will follow, though overall performance also depends on other factors, such as latency. Here is the list of bandwidth monitoring tools for your network bandwidth bmon bwbar bwm bwm-ng iftop iperf ipfm speedometer cbm Support UbuntuGeek Sponsor ibmonitor pktstat mactrack Favourite Sites MRTG Cacti My Daily Tech Tips Debian Admin Now we will see each DebianHelp Login/Register tool separately Tuxmachines Log in Unixmen bmon Archives bmon is a portable Select Month bandwidth monitor and rate estimator running on various operating systems .

  • Linux Hacking Case Studies Part 4: Sudo Horror Stories
    Linux Hacking Case Studies Part 4: Sudo Horror Stories written by Scott Sutherland | March 26, 2020 This blog will cover different ways to approach SSH password guessing and attacking sudo applications to gain a root shell on a Linux system. This case study commonly makes appearances in CTFs, but the general approach for attacking weak passwords and sudo applications can be applied to many real world environments. This should be a fun walk through for people new to penetration testing. This is the fourth of a five part blog series highlighting entry points and local privilege escalation paths commonly found on Linux systems during network penetration tests. Below are links to the first three blogs in the series: Linux Hacking Case Study Part 1: Rsync Linux Hacking Case Study Part 2: NFS Linux Hacking Case Study Part 3: phpMyAdmin Below is an overview of what will be covered in this blog: Finding SSH Servers Dictionary Attacks against SSH Servers Viewing Sudoers Execution Options Exploiting Sudo sh Exploiting Sudo VI Exploiting Sudo Python Exploiting Sudo Nmap Finding SSH Servers Before we can start password guessing or attacking sudo applications, we need to find some SSH servers to go after. Luckily Nmap and similar port scanning tools make that pretty easy because most vendors still run SSH on the default port of 22. Below is a sample Nmap command and screenshot to get you started. nmap -sS -sV -p22 192.168.1.0/24 -oA sshscan Once you’ve run the port scan you can quickly parse the results to make a file containing a list of SSH servers to target.

  • Secure Automation: Achieving Least Privilege with SSH, Sudo and Setuid Robert A
    Secure Automation: Achieving Least Privilege with SSH, Sudo and Setuid Robert A. Napier – Cisco Systems ABSTRACT Automation tools commonly require some level of escalated privilege in order to perform their functions, often including escalated privileges on remote machines. To achieve this, developers may choose to provide their tools with wide-ranging privileges on many machines rather than providing just the privileges required. For example, tools may be made setuid root, granting them full root privileges for their entire run. Administrators may also be tempted to create unrestricted, null-password, root-access SSH keys for their tools, creating trust relationships that can be abused by attackers. Most of all, with the complexity of today’s environments, it becomes harder for administrators to understand the far-reaching security implications of the privileges they grant their tools. In this paper we will discuss the principle of least privilege and its importance to the overall security of an environment. We will cover simple attacks against SSH, sudo and setuid and how to reduce the need for root-setuid using other techniques such as non-root setuid, setgid scripts and directories, sudo and sticky bits. We will demonstrate how to properly limit sudo access both for administrators and tools. Finally we will introduce several SSH techniques to greatly limit the risk of abuse including non-root keys, command keys and other key restrictions. Introduction to files writable only by a particular group. For exam- ple, in FreeBSD programs that read system memory Since its introduction in 1995 by Tatu Ylonen, are setgid to a special kmem group.

  • Page 1 of 3 Sudo (Super User Do) Is a Very Useful
    Sudo Sudo (Super User Do) is a very useful program that allows a system administrator to give certain users the ability to run some (or all) commands as root 1. Download the source code: The source of sudo is available from http://www.courtesan.com/sudo/. At the time of writing, the latest version is V1.6.3 and the source code is provided as a compressed tar archive in the file sudo- 1.6.3.tar.gz . Download this file to a temporary directory, such as /tmp. 2. Prepare the source code for compilation: Log in as root, make a directory at a convenient point in the file system to hold the source code and copy the source into this directory. For example: # mkdir -p /opt/source/sudo # cd /opt/source/sudo # cp /tmp/sudo-1.6.3.tar.gz . Unzip and untar the source and then change to the directory created by tar: # gunzip sudo # tar xvf sudo # cd sudo-1.6.3 At this point, you may like to have a look at the README, INSTALL and FAQ files. 3. Compile the source code and install sudo: Configure the compilation process for your system: # ./configure Compile the source code: # make And install the compiled code: # make install This install the sudo program into /usr/local/bin, the visudo script (see later) into /usr/local/sbin and the manual page into subdirectories of /usr/local/man. 4. Modify the search path: If you haven't already done so for other software, you now need to modify the search paths so that the system can find the sudo program and its manual pages.
