Hi,
My situation is practically identical to post titled, "Putty PSCP hangs?", but this is appears to be 1.5 decades later and with psftp.
I have been using psftp for years with no issues, and in the past couple weeks I am getting this situation:
When logging into my hosted web server to up/download files, I get past the point of entering the password and then it just hangs. Below is what I'm talking about. The prompt I'll use here is $, and I've replaced IP address with x's, and other sensitive
data similarly changed.
$ psftp -v xxx.xxx.xxx.xxx
Connecting to xxx.xxx.xxx.xxx port 2222
We claim version: SSH-2.0-PuTTY_Snapshot_2018_03_14.a624786
Server version: SSH-2.0-OpenSSH_5.3
We believe remote version has SSH-2 channel request bug
Using SSH protocol version 2
Doing Diffie-Hellman group exchange
Doing Diffie-Hellman key exchange with hash SHA-256
Server also has ssh-dss host key, but we don't know it
Host key fingerprint is:
ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx
Initialised AES-256 SDCTR client->server encryption
Initialised HMAC-SHA-256 client->server MAC algorithm
Initialised AES-256 SDCTR server->client encryption
Initialised HMAC-SHA-256 server->client MAC algorithm
Using username "username".
Attempting keyboard-interactive authentication
Server refused keyboard-interactive authentication
username@xxx.xxx.xxx.xxx's password:
Sent password
Access granted
Opening session as main channel
Opened main channel
Started a shell/command
Connected to xxx.xxx.xxx.xxx
^C
$
Typing CTRL-C gets me back to the command prompt. If you type anything after the Connected line (not CTRL-C), it buffers at the local PC - it's not a terminal echo kind of thing.
I was using psftp 0.69, then just tried 0.70, and you can see in the verbose output I was just trying the latest snapshot. I am on Win7 Pro, 64-bit, and simply use a cmd.exe prompt to run psftp. I CAN run plain old Windows ftp.exe without issue. I
should also mention that a Putty SSH session works fine as well.
Does anyone have any suggestions? I don't believe it's necessarily a bug, but could there be some kind of RSA cache thing that's causing this, or does something in the verbose output ring any bells, or ...?
Thanks!
