SFTP ISSUES
We have faced couple of sftp connectivity issues in our non prod environments in the past one week. Here is brief description about the issues and how we resolved them. Issue 1: sftp connection hangs without throwing any error. Public ip of one of the third party applications we are connecting got changed. We sent change in firewall rule to our firewall team. Team made change post that too we were not able to connect sftp server. Here is the verbose output: sftp -vvv -P 22222 user@104.x.x.x OpenSSH_7.4p1, OpenSSL 1.0.2k-fips 26 Jan 2017 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 58: Applying options for * debug2: resolving “104.x.x.x” port 22222 debug2: ssh_connect_direct: needpriv 0 debug1: Connecting to 104.x.x.x [104.x.x.x] port 22222. debug1: Connection established. debug1: identity file /home/user/.ssh/id_rsa type 1 debug1: key_load_public: No such file or directory debug1: identity file /home/user/.ssh/id_rsa-cert type -1 de...
