It has listings of all. I hope this now will be a bit more clear. By deleting the old and creating a new VPN adapter does not change the situation. The same error code 2 is the result. The properties tag appears to be normal. It says that the device is working properly. Besides I don't know what to look for or what to modify.
This adapter was disabled, but when the step 2. Also, the most frequent cause of it is interference from firewalls or other third party security applications. Unfortunately these kinds of interference are pretty difficult to troubleshoot. Try to temporarily disable firewall s on your side. Sorry, I don't think I will be able to assist you better than this. Then I moved on to the other procedure you described in the Posted: Mon Mar 27, pm.
But there are some questions; In the step 4, a particular server was selected arbitrarily to obtain. If this particular server became unavailable in future all will go through such an experience from time to time. In the step 5. The unrestricted area in the table below means within the scope of the architectural and memory limits. Where a Configuration file has been created on the VPN Server of one computer, by copying its contents verbatim to another computer, it is possible to launch the VPN Server of the other computer using equivalent configuration information.
Clicking on [Edit Config. It is also possible to save the file in UTF-8 format. The same function can also be used to upload a Configuration file prepared on the Administrator's client terminal.
When uploading and writing the Configuration file, the server function of the VPN Server automatically reboots and reads the contents of the new Configuration file. Manual rebooting or rebooting of the VPN Server process itself are not required. Upon completion of the reboot and Configuration file read, the VPN Server commences operation based on the contents of the new Configuration file. The same task can be carried out using the vpncmd utility's [ConfigGet] and [ConfigSet] commands.
The contents of the VPN Server's Configuration file is automatically replaced in the following situations. While the contents of the Configuration file are replaced in the case of both 1 and 2 above, the renewed data in 1 is part of the VPN Server settings data and is thus essential by definition, while in 2, the renewed data is often not overly important.
As such, by incrementing increasing the value of the Configuration file version information one at a time only when a change to the settings is carried out on the VPN Server, as is the case in 1, the System Administrator is able to know how many times the Configuration file settings have been modified.
When wishing to adopt a method of specifying an external script, for instance, when automatically backing up the Configuration file only when its settings have been changed as in the case of 1 , and not backing up when only statistical data has been updated as is the case in 2 , it is advisable to check the version information within the Configuration file each time, and if its value has increased on that of the previous check, to perform a backup of said file.
The configuration version number is written in the upper part of the Configuration file by the [uint type] named [ConfigRevision]. In the example above, it can be seen that the settings of the Configuration file have been changed times since it was first created.
The contents of the Configuration file are created by the time and effort of the VPN Server and Virtual Hub Administrators and as such, are very valuable. A great deal of work is required in order to restore the settings of the Configuration file in the event of corruption due to a hardware or software bug, or becoming unable to be returned to its original settings due to erroneous settings changes.
That is why the VPN Server records the history of the Configuration file contents at regular intervals and automatically backs it up. The Configuration history backup is saved in the directory named backup. If the VPN Server settings information is corrupted or erroneous settings such as deleting an important Virtual Hub are performed, the most recently saved Configuration file backup can be restored manually.
Please refer to the section in 3. A Configuration file backup is created automatically once every 60 minutes. However, as a general rule, no backup is created when there have not been any changes made to the contents of the Configuration file. In default, the backup folder is automatically protected using the same permission settings as the Configuration file. In addition to recording settings entries for the entire VPN Server settings, Virtual Hub and user groups settings, the configuration data administered by the VPN Server also records statistical information on each of these objects.
Statistical information refers to the following types of data differs depending on the object recorded. The above information is statistically processed by the VPN Server automatically and written as part of the Configuration file the ConfigRevision value does not increase even if the statistical information alone is changed as previously stated.
Statistical information on a Virtual Hub and its individual objects can only be read by an Administrator with Virtual Hub administration authority for that hub including the overall System Administrators.
This information is fundamentally read only, and cannot be rewritten using the VPN Server Manager or vpncmd utility.
It is technically possible however, to directly rewrite the Configuration file using a text editor. The statistical information provides a range of information to the System Administrator such as how often the VPN Server and Virtual Hub users communicated, how many times they connected to the VPN Server and when the last connection and communication occurred. The VPN Server updates all statistical data in real time.
This means that if a request to obtain statistical data from the VPN Server Manager or vpncmd utility occurs, then the latest up-to-the-minute statistical data can be acquired. Successively clicking on [Refresh] with the mouse in the VPN Server Manager GUI if the object in question is established clearly shows the values being constantly updated. It is also a simple task to acquire the Configuration file and process that mechanically. When configuring a cluster from a plurality of VPN Servers, real time statistical information on the entire cluster is regularly gathered by the VPN Server which is the cluster controller.
Therefore, when wishing to know the communication volume of the entire cluster during its configuration, establish an Administrator connection and acquire the necessary statistical information. The VPN Server writes the following files in the same directory as the vpnserver executable file or its subdirectory while running.
These log files and history files consume a large amount of disk space when the VPN Server has been operating over a long period.
However, log files created by the VPN Server should not be erased indiscriminately because data from the VPN Server log, Virtual Hub packet log and security log is crucial when examining the causes of unauthorized access and other trouble. It is also possible to automate their processing.
However, when not carrying out the above processing or when forgetting to back up or delete old log data, disk space becomes constricted and eventually reaches 0 bytes. When available disk space reaches 0 bytes, the VPN Server becomes unable to write new log data onto the disk. This situation represents a major risk to security because an intruder can commit any type of attack they please and it will not be recorded on the log so the VPN Server Administrator has no way of knowing later on that an attack has taken place.
To counter this risk, the SoftEther VPN Server incorporates a feature whereby all of the log files and configuration files written by the VPN Server are automatically deleted starting from the oldest file whenever the available disk space falls below a preset level due to constriction of disk space caused by a large amount of saved log files and history files.
By deleting old log files of less importance, it is possible to continually ensure a prescribed amount of available disk space thereby maintaining the ability to write log files as much as possible. By taking advantage of this function of automatically deleting old log files to keep disk space above a certain level, it is possible to realize maintenance free operation even when not performing the administrative task of backing up and deleting old log files. The VPN Server is set by default to delete old log files starting with the oldest until the space available on the drive to which the log files are being written is restored to MB or greater , , bytes to be precise.
It should be noted that the minimum value is 1MB precisely 1,, bytes and it is not possible to set a value below this. Please refer to the area below for details. The Windows and Linux operating systems on which the SoftEther VPN Server program and the VPN Server rely are carefully designed and implemented to realize a high level of reliability and stability, and the number of errors which exist within their programs are very few.
However, it is impossible to guarantee above a certain extent that errors will definitely not occur in any program, so System Administrators should always consider what measures to take in the event that a serious error occurs.
Even assuming that the problem does not lie with the software, consideration should also be given to potential hardware defects. For instance, it cannot be said with any certainty that the error is not caused by the memory module or a mistaken calculation by the CPU.
In many cases where there is software or hardware defect, errors occur which are either difficult or impossible to repair such as a memory access violation, calling up an unknown directive or an unauthorized interrupt. It then re-launches the process, re-reads the contents of the Configuration file and attempts to continue operation. These processes are typically carried out in an instant from a few milliseconds to a few seconds so, on the whole, there is no significant disturbance to the VPN Server.
This means that when an irreparable error occurs in the user's memory space, the VPN Server program attempts failure recovery automatically, thereby eliminating the need for the VPN Server Administrator to notice the error and re-launch the VPN Server process and so on. If a hardware failure such as a sudden power outage occurs when the VPN Server program is attempting to write physical data to the Configuration file, the physical contents of the Configuration file may be damaged.
In preparation for such an occurrence, the VPN Server always carries out a duplicate procedure when writing the Configuration file. First, it physically leaves the contents of the Configuration file on the disk, then it writes the contents of the new Configuration file onto the disk. Once the write processing is complete, it issues a command to the OS's write buffer to flash and goes on standby until the data write is committed to physical disk. After the physical data is committed, the old configuration data is then deleted.
These processes are carried out in a location of which the user is completely unaware. When there is a chance that the Configuration file will be damaged upon the next launch, an attempt is made to repair the contents of the configuration using the data from the prior configuration backed up in the log immediately before writing the damaged Configuration file.
In most cases, this is successful and the contents of the configuration are restored. These processes are performed automatically the next time the system is restored, so the System Administrator does not have to perform them manually. When this automatic failure recovery function does not work properly, the VPN Server's Administrators must manually roll back to the previous Configuration file from the Configuration file's backup directory. This function may also not work properly depending on the specifications of the operating system and file system.
The VPN Server automatically saves the Configuration file note that no automatic save occurs when there has been no change whatsoever to the information contained in the Configuration file including the statistical information. If, after executing the check command, the message "Passed all checks. If, however, the system fails at any of the above check items, we recommend checking 7. The following startup script is a description example, and you may have to rewrite part of the script for it to work properly on your system.
Lastly, use the chkconfig command to allow the above startup script to start automatically in the background when the Linux kernel starts. VPN Server registered as a service mode program automatically starts when Linux starts and automatically stops when Linux shuts down. You can manually stop or restart the VPN Server service if you need to do so for management reasons.
It is unlikely that VPN Server would malfunction due to a problem with the physical memory of the computer or a software bug. If this should occur and the VPN Server service does not respond when you try to stop the service using the method above, you can stop the service by forcibly terminating the vpnserver process.
For the detailed method for forcibly terminating the vpnserver process, please refer to the method of using the kill command described in 3. When starting VPN Server as a user mode program with general user rights, the program cannot be registered as a system service, but when a general user starts the VPN Server program in the background by typing [.
