It appears you are experiencing issues when attempting to transfer files using the free LAN messenger application from SourceForge. The problem manifests as the file transfer getting stuck in a "calculating time" status instead of completing the file transfer.
This type of problem is often indicative of connectivity or network configuration issues between the systems attempting the file transfer. Some troubleshooting steps I would recommend are:
- Verify both systems have the latest version of the LAN messenger software and that firewalls or security software are not blocking the application.
- Check that file and printer sharing is enabled on both systems and configured properly in the application.
- Confirm both systems are on the same LAN subnet and network discovery is enabled.
- Try adjusting MTU settings on the NICs to rule out MTU mismatch issues.
- Check switch port configurations are not limiting bandwidth via QoS or speed/duplex settings.
- Attempt file transfers with a different piece of software like FTP to determine if the problem is isolated to the LAN messenger tool.
Let me know if the transfers succeed after trying these steps. Optimizing connectivity and network configuration between systems is crucial for reliable file transfer performance.
I have the same problem between two pc's with different windows versions.
From 7 to 8.1 the file transfer works flawlessly, but from 8.1 to 7 it stays on "calculating time" forever.
The pc's are connected through ethernet and are on the same network.
I tried with the firewalls disable on both of them and got the same result as before.
Any ideas on what to try next to fix it?
Thx.
"This is an older thread, but for anyone else experiencing similar issues with file transfers failing or having very slow transfer speeds, the cause may be a duplex mismatch between the source and destination network ports. It's recommended to verify that both ports are configured for full duplex mode rather than half duplex to resolve this type of problem and achieve maximum file transfer performance. The duplex settings should be checked on the network interfaces of the systems on each end of the file transfer connection. Configuring the relevant ports for full duplex operation can resolve transfer failures and sluggish speeds that are sometimes encountered due to duplex mismatches."
