How to Disable SSL for Webmin

Webmin is a Web application that enables administrators to manage Linux servers. Webmin runs on a Web server at port 10000. Miniserv is the name of the Web server application that handles the Webmin Web application. By default, Miniserv uses SSL. However, you can disable SSL for Webmin Miniserv by editing the configuration file for the Web application. With SSL disabled, you can access the Webmin application over a standard HTTP connection.

Step 1
Open a terminal window on the Linux server. You can also SSH into the server if you do not have physical access to the machine.

Step 2
Type the following command at the command prompt and press the “Enter” key:
nano /etc/webmin/miniserv.conf
This command opens the Miniserv configuration file in the Nano text editor.

Using SSL with Webmin Fix SSL error

SSL Error On First Access of Webmin on New Install - (Error code: ssl_error_rx_record_too_long)

If you try to log into a new install and you receive this error:
An error occurred during a connection to xxx.xxx.xxx.xxx:10000.
SSL received a record that exceeded the maximum permissible length.
(Error code: ssl_error_rx_record_too_long)
It is because SSL is not configured for Webmin and it must be enabled.
Solution:

Because your Webmin login and password are normally passed between your browser and the server in unencrypted form, an attacker with access to any of the networks between the browser and server can easily capture your Webmin login. To prevent this, Webmin can be configured to use SSL to encrypt all of its network traffic.

If you have yum support on your linux distribution following will resolve SSL issue.
yum install openssl openssl-devel perl perl-Net-SSLeay perl-Crypt-SSLeay

Else follow below method.

Setting up a SFTP Server on Windows

I recently had to create an SFTP server on our work development system, and after doing a fair bit of Googling on the topic found a good solution. The solution is a combination of research done at differnt sites. It is this solution that I am sharing in hopes that it will help someone else. This tutorial will help you turn your Windows based system into a SecureFTP server.

Background

Secure Shell (SSH) is a program that lets you log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another. It provides strong authentication and secure communications over insecure channels. When using ssh, the entire login session, including transmission of password, is encrypted and therefore is very secure.

You may have noticed that many webhosts allow ssh access. This means that you can login to their webserver and execute many UNIX commands (the ones they allow you access to) on your account. Not only can you connect to other computers that provide SSH access, but you can also allow others to connect to your computer using SSH.

Ans: The Pseudonode ID is the last octet of a LAN ID. Its purpose is to distinguish LAN IDs which are originated by a single router which is the DR on multiple LANs.  

Q203: What is the maximum age (MaxAge) of an IS-IS LSP?  
Ans: The MaxAge of an IS-IS LSP is 1200 seconds (20 minutes).

CCNP Job Interview Questions & Answere Part 2  

Q101: What is a recursive table lookup?  
Ans: A recursive routing table lookup occurs when a router cannot acquire all the information it needs to forward a packet with a single routing table lookup. For example, the router may perform one lookup to find the route to a destination and then perform another lookup to find a route to the next hop router of the first route.  

Q102: What is a routing protocol?  
Ans: A routing protocol is a "language" that routers speak to each other to share information about  
     network destinations.  

Q103: What basic procedures should a routing algorithm perform?  
Ans: At a minimum, a routing protocol should define procedures for  
     Passing reachability information about networks to other routers  
     Receiving reachability information from other routers  
     Determining optimal routes based on the reachability information it has and for recording  
     this information in a route table  
     Reacting to, compensating for, and advertising topology changes in an internetwork

Q1. What are three types of LAN traffic?
Ans. Unicasts - intended for one host.
Broadcasts - intended for everyone.
Multicasts - intended for a only a subset or group within an entire network.

Q2. What are unicast frames?
Ans. Unicast frames are the most common type of network traffic. A unicast frame is a frame intended for only one host. The only station that processes this frame is one station that has its own MAC address in the destination portion of packet.

Q3. How do you enable IGRP on a Cisco router?
Ans. The way you enable IGRP on a Cisco router is similar to the way you enable RIP, except you specify IGRP as the protocol and add an autonomous system number. For example:
RouterA(config)# router igrp 10 (10 is the AS number)
RouterA(config-router)# network 192.168.0.0
RouterA(config-router)# network 192.168.1.0
RouterA(config-router)# network 192.168.2.0

How to Fix Svchost.exe High memory usage

A few days ago I noticed that svchost.exe was using a lot of memory making my OS very slow. Sometimes, when my computer is frozen and just about unusable, it seems that the cause is some heavy background processing. Sometimes, I can catch who is using all my disk-bandwidth using Resource Monitor (such details are not shown in task manager). I suspect that this svchost.exe instance is really showing the activity of the service for Windows Update, but I am not sure if I can find out for sure.
Here's what I see:

Attackers are able to easily monetize stolen credit card data

When consumers make purchases from a retailer, the transaction is processed through Point-of-Sale (PoS) systems. When a credit or debit card is used, a PoS system is used to read the information stored on the magnetic stripe on the back of the credit card. Once this information gets stolen from a merchant, it can be encoded into a magnetic stripe and used with a new card. Criminal markets exist for this valuable information because the attackers are able to easily monetize stolen credit card data. Incidents involving PoS malware have been on the rise, affecting many large organizations as well as small mom-and-pop establishments and garnering a lot of media attention. The presence of large amounts of financial and personal information ensures that these companies and their retail PoS systems will remain attractive targets.

Howto enable SSH public key authentication on Ubiquiti AirOS v5.5.8 (e.g. Airgrid, NanoStation2)

About SSH Keys

SSH keys provide a more secure way of logging into a Ubiquiti AirOS device with SSH than using a password alone. While a password can eventually be cracked with a brute force attack, SSH keys are nearly impossible to decipher by brute force alone. Generating a key pair provides you with two long string of characters: a public and a private key. You can place the public key on any server, and then unlock it by connecting to it with a client that already has the private key. When the two match up, the system unlocks without the need for a password. You can increase security even more by protecting the private key with a passphrase.

Step One—Create the RSA Key Pair

The first step is to create the key pair on the Aircontrol Server machine (OR it be your computer):
ssh-keygen -t rsa
