Team, I'm not sure when this started, but I know for sure I was able to do this in the past.
I'm running cygwin on Windows 10 and want to connect to an SFTP server using the 'sftp' command. Note that when I try to connect to the same SFTP server using a different client, File Zilla, it works. When I run sftp, it appears to hang. I've run it with -vvvv to get some debugging output and get the following: 1001 jdk16->> sftp -vvvv -P 2100 192.168.160.62 OpenSSH_8.8p1, OpenSSL 1.1.1l 24 Aug 2021 debug1: Reading configuration data /cygdrive/c/Users/mark.hansen/.ssh/config debug1: /cygdrive/c/Users/mark.hansen/.ssh/config line 1: Applying options for * debug1: Reading configuration data /etc/ssh_config debug1: /etc/ssh_config line 46: Applying options for * debug2: resolve_canonicalize: hostname 192.168.160.62 is address debug3: expanded UserKnownHostsFile '~/.ssh/known_hosts' -> '/cygdrive/c/Users/mark.hansen/.ssh/known_hosts' debug3: expanded UserKnownHostsFile '~/.ssh/known_hosts2' -> '/cygdrive/c/Users/mark.hansen/.ssh/known_hosts2' debug3: ssh_connect_direct: entering debug1: Connecting to 192.168.160.62 [192.168.160.62] port 2100. debug3: set_sock_tos: set socket 4 IP_TOS 0x48 debug1: Connection established. debug1: identity file /cygdrive/c/Users/mark.hansen/.ssh/id_rsa type 0 debug1: identity file /cygdrive/c/Users/mark.hansen/.ssh/id_rsa-cert type -1 debug1: identity file /cygdrive/c/Users/mark.hansen/.ssh/id_dsa type -1 debug1: identity file /cygdrive/c/Users/mark.hansen/.ssh/id_dsa-cert type -1 debug1: identity file /cygdrive/c/Users/mark.hansen/.ssh/id_ecdsa type -1 debug1: identity file /cygdrive/c/Users/mark.hansen/.ssh/id_ecdsa-cert type -1 debug1: identity file /cygdrive/c/Users/mark.hansen/.ssh/id_ecdsa_sk type -1 debug1: identity file /cygdrive/c/Users/mark.hansen/.ssh/id_ecdsa_sk-cert type -1 debug1: identity file /cygdrive/c/Users/mark.hansen/.ssh/id_ed25519 type -1 debug1: identity file /cygdrive/c/Users/mark.hansen/.ssh/id_ed25519-cert type -1 debug1: identity file /cygdrive/c/Users/mark.hansen/.ssh/id_ed25519_sk type -1 debug1: identity file /cygdrive/c/Users/mark.hansen/.ssh/id_ed25519_sk-cert type -1 debug1: identity file /cygdrive/c/Users/mark.hansen/.ssh/id_xmss type -1 debug1: identity file /cygdrive/c/Users/mark.hansen/.ssh/id_xmss-cert type -1 debug1: Local version string SSH-2.0-OpenSSH_8.8 debug1: kex_exchange_identification: banner line 0: 220 Welcome to AT FTP service debug1: kex_exchange_identification: banner line 1: 530 Please login with USER and PASS. ... after some time ... debug1: kex_exchange_identification: banner line 2: 421 Timeout. kex_exchange_identification: Connection closed by remote host Connection closed by 192.168.160.62 port 2100 Connection closed Here is my local config file (.ssh/config): Host * Protocol 2 ForwardX11Trusted yes ForwardX11 yes Here is /etc/ssh_config: Host * ForwardX11 yes Yesterday, I upgraded to the latest cygwin packages and now the cygwin DLL is version 3.3.2 I tried running the command with the login user name on the command line (user@192.168.160.62) and assuming it was just waiting for the password, I tried entering it, but the characters were just echoed to the terminal and the process continued to hang. Any idea what is causing this? What can I do to troubleshoot this further? -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
