The issue is triggered by calling dropbear with parameter -W . If  is 
larger than 32768, coping of large files does fail.

If option RecvWindowSize is not set in the dropbear configuration, a default 
window size of 262144 is used, which triggers the issue.

dropbear - compression is broken

2024-02-26 Thread e9hack

Hi,

in the past, it was possible to enable compression in WinSCP. Currently WinSCP 
reports an error when the copy operation starts:

Copying file 
'D:\Download\carambola\openwrt-ath79-generic-tplink_archer-c7-v2-2-squashfs-sysupgrade-d240224.bin'
 fatally failed.
Copying files to remote side failed.

Logread shows the following message:
