Putty: Moving or Getting Command Fails with Network Error: Software Caused Connection Abort
PuTTY is a popular SSH and telnet client that is widely used for managing remote servers. However, sometimes users may encounter network errors, such as "Software caused connection abort," while moving or getting commands using PuTTY. This article will discuss the possible causes of this issue and provide solutions to resolve it.
Understanding the Issue
The "Software caused connection abort" error is typically caused by a network issue that interrupts the connection between the client and the server. In the case of PuTTY, this error can occur when moving or getting commands, which can be frustrating for users who need to perform critical tasks on remote servers.
Possible Causes
There are several possible causes of this issue, including:
- Network instability or intermittent connectivity issues
- Firewall or security software blocking the connection
- PuTTY settings that are not optimized for the network or server
- Server-side issues, such as high load or resource constraints
Solutions
To resolve the "Software caused connection abort" error in PuTTY, users can try the following solutions:
Check Network Connectivity
Users should first check their network connectivity to ensure that there are no issues with their internet connection. They can try accessing other websites or servers to confirm that their network is working correctly.
Disable Firewall or Security Software
Firewall or security software can sometimes block the connection between the client and the server. Users can try disabling their firewall or security software temporarily to see if it resolves the issue.
Optimize PuTTY Settings
Users can optimize their PuTTY settings to improve the connection between the client and the server. They can try increasing the timeout settings, enabling keepalives, or adjusting the MTU size to see if it resolves the issue.
Check Server-Side Issues
Users should also check for any server-side issues that may be causing the connection abort error. They can try contacting their server administrator or checking the server logs to identify any issues that may be causing the error.
Code Block
Here is an example of how to optimize PuTTY settings to improve the connection between the client and the server:
1. Open PuTTY and enter the server details.
2. Go to the "Connection" category.
3. Under "Sending of null packets to keep session active," enable "Keepalives."
4. Under "Seconds between keepsalives," set a value of 30.
5. Under "MTU size," set a value of 1400.
6. Click "Open" to connect to the server.
