What is IRAFHOSTS file?

How to open IRAFHOSTS file?

The main problem with IRAF User is that the IRAFHOSTS file is incorrectly associated with programs. Thus, when you open IRAFHOSTS, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the IRAFHOSTS file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install IRAF

The first step is to check if the computer has the IRAF program installed. The easiest method is to use the system search engine by entering the program name IRAF in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file IRAFHOSTS with IRAF. Later in this article you will find a list of programs that can open IRAFHOSTS files.

Programs to open IRAFHOSTS file

Remember to download programs supporting IRAFHOSTS files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of IRAF with IRAFHOSTS files

If, despite the installed application, the IRAFHOSTS file does not start in the IRAF application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the IRAFHOSTS file with the IRAF program.

Step 3. Update IRAF to the latest version

If, however, after binding IRAF with IRAF User there were still problems, you should update the program to the latest version. In this case, use the NOAO website or update the program from the application.

Step 4. Check for the following problems with the IRAFHOSTS file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

The IRAFHOSTS file may be unusually small compared to the original file. Usually this applies to IRAFHOSTS files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file IRAFHOSTS or the program directory. As a result of the scan, sometimes it is not possible to recover IRAFHOSTS files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of IRAFHOSTS file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair IRAFHOSTS file corruption. The easiest way to restore the file is from a backup or by contacting NOAO, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted IRAFHOSTS files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the IRAFHOSTS file to another location.
This problem only occurs with more complex files. In this case, the IRAFHOSTS file is blocked by the first application to open it. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
