- 2019-7-21 Dear friends, I am using a Windows 7 32-bit version of operating System. I have been trying to access Chumby from my OS. However while doing so I encounter error that I have never come across before. The command stops after nearly half an hour with the message stated below PuTTY Fatal Error “Network error: Software caused connection abort”.
- WinSCP’s 'Network error: Software caused connection abort' Message is Driving Me Crazy! Lowell Heddings @lowellheddings October 19, 2007, 5:17am EDT WinSCP is by far and away the best SCP/SFTP client for Windows users, but the default settings don’t use keepalive, so you get disconnected far too often.
2019-8-23 I have a problem with my Raspberry Pi 3. When I want to connect to my Raspi, after a few attempts it works, but after while (like 1 minute) it says this error: 'Software caused connection abort'. Stack Exchange Network Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
I have had this problem on my laptop for months. If I connect from any other computers (local or remote) I have no problems with the same user.
THE PROBLEM:
Using Putty on Windows 10, I can connect to the server, put in username. As soon as I hit enter I see the prompt for the password but I also get a message:
'Network error. Software caused connection abort'
When I click ok the window goes inactive.
This happens on Putty. It also happens when trying to connect WinSCP on the same PC. If I try on my desktop there is no issue. This happens every single time I try to connect.
WHAT I TRIED:
- New IP address
- Reinstall Putty and WinSCP
- Reset Router
Checked server logs ('groot sshd[10669]: Connection reset by 192.168.1.1 port 54916'
That is the only line that comes up in the log when I try to connect.
EDIT:
I recently put in a Wifi access point in another location than our main one. I decided to try this and it worked. It must be something to do with the wifi router. I think it also happens when sending keys because I tried connecting to a different server and as soon as I clicked yes on confirming a new key the window went inactive with the same error.
EDIT 2: Event log drop

Also try setting in Putty for the profile you are defining,
Connection -> SSH -> Host Keys Manually configure host keys for this connection Host keys or fingerprints to accept In the 'Add key' field, enter the fingerprint identified in the log. In your case ssh-rsa 2048 b4:e3:25:2f:b5:01:1a:96:28:6d:c1:2c:e4:fd:7d:de Click 'Add key' and it should appear in the accepted list.
Test your connection.

Putty Network Error Software Caused Conne…
I have RHEL 6.8 Machine installed in a VM. I moved one file libc.so.6 from /lib64/ to /lib64/backup/. Since then I am not able to connect to that machine through Putty or WinSCP. Both the tools give the same error. Software caused connection abort.
As I haven't created this VM, I don't have permission to restart it. But will restarting the machine, solve the issue ? What can be the solution for this situation, except re-installing the OS ?

libc.so.6 is the standard C library and by moving it you borked your system quite well.
The error you get means that SSH connection cannot be established.
All you can do now is access the machine via the console and restore the file in its original position.
dr01dr01The time-saving workaround is to reinstall the OS.
Note :- Reinstalling the OS will solve the issue, but you'll lose all the installed software and the data. That's why it is a workaround and not the solution.
