Fixing SSH/SFTP client connection issues involving Diffie-Hellman-Group1-SHA1

When you’re troubleshooting connectivity issues between Secure Shell (SSH)/Secure File Transfer Protocol (SFTP) clients and servers, it pays to inspect the error messages generated on both sides of a connection. Those messages often provide vital clues about the problem. If your error messages involve the Diffie-Hellman-Group1-SHA1 key exchange algorithm, you’ll want to stick around. In the succeeding sections, we’ll be discussing the underlying cause of this particular issue and how to fix it.

Load balancing file transfer services

Overview If your organization regularly handles heavy file transfers, then you will have to consider load balancing your file transfer services. In this post, we'll take a quick look at the reasons for load balancing file transfer services, what a simple load balancing configuration looks like, and how you can deploy load balanced file transfer services using JSCAPE MFT Gateway.

Running reports using search results in JSCAPE MFT server

Do you wish you could run reports on your JSCAPE MFT Server based on specific search results that were previously created on the Logging module? This capability can be particularly useful during audits or investigations, when you would like to get finer levels of reporting regarding your file transfers.

What is a Cipher? | Understanding Encryption Algorithms

Overview The strength of an encryption largely depends on two components: 1) the cipher and 2) the length of the key. We already discussed key lengths in an older post. So today, let's talk about the other component.

Applying AS2 Encryption

Overview If your AS2 connection already runs over HTTPS, your EDI messages should already be protected by the data-in-motion encryption that comes with SSL/TLS. But what if you want an added layer of security or if you're somehow only using HTTP and want to encrypt your transmission? You'll need something like this.

What is an SSL File Transfer? | FTP-SSL | JSCAPE MFT Server

Overview: What is an SSL File Transfer? SSL file transfer is a term sometimes used in referring to a secure file transfer protocol known as FTPS or FTP-SSL. FTP is a network protocol used for transferring files, while SSL is a protocol for encrypting information sent over a network. This post is meant to help users understand what FTPS is and what it is capable of doing, particularly in terms of enhancing the security of your file transfers. We can also show and tell when you request a free trial.

Install A Linux SFTP Server Via Command Line And Configure Via Web UI

Overview Let's say you want to install an SSH FTP server (SFTP) on a Linux machine devoid of a GUI. However, after installation, you don't want to configure it (add users, create keys, enable public key authentication, choose algorithms, etc.) locally, moreso via the SFTP client. Instead, you want this SFTP server to be configured remotely through a graphical Web user interface. This is how we recommend you do it.

What Is HMAC (Hash-based message authentication code), And How Does It Secure File Transfers?

An Overview of HMAC Data integrity checks are vital to secure communications. They enable communicating parties to verify the integrity and authenticity of the messages they receive. In secure file transfer protocols like FTPS, SFTP, and HTTPS, data integrity/message authentication is usually achieved through a mechanism known as HMAC (Hash-based message authentication code). In this post, we explain what HMAC is, its basic inner workings, and how it secures data transfers.

What ICAP antivirus scanning means for your file transfers

Internet content adaptation protocol (ICAP) antivirus scanning, enabled within JSCAPE MFT Server by Redwood, offloads virus detection to a dedicated server, boosting system efficiency and security. It allows real-time malware checks and enhances compliance with the Health Insurance Portability and Accountability Act (HIPAA) and Payment Card Industry Data Security Standard (PCI DSS) without the local system's burden. This method ensures secure, seamless file transfers across all protocols, which simplifies administration and maintains up-to-date protection. One of the key features of JSCAPE MFT Server by Redwood is the ability to support ICAP antivirus scanning. But what is it? How can it benefit your end-users, trading partners and system administrators? How does it compare to traditional file transfer virus scanning solutions? In this blog post, we answer these questions and more. ICAP benefits ICAP, as defined in RFC 3507, allows JSCAPE MFT Server to offload virus scanning tasks to a dedicated ICAP server, enhancing security policies without burdening the local server with the heavy lifting. This advanced scanning method enables real-time antivirus checks by forwarding HTTP messages to an ICAP service for evaluation.

How to FTP a file | How to download files from FTP

For several decades, the file transfer protocol (FTP) served as the de facto method for transferring files across the internet. Organizations used FTP transfers to move multiple files or large files from one geographical location to another. Some businesses, for example, use FTP to upload files from their local PC to their web server.
