Title: BackWPup ssh failure Last modified: February 3, 2022 --- # BackWPup ssh failure * Resolved [dnessett](https://wordpress.org/support/users/dnessett/) * (@dnessett) * [4 years, 4 months ago](https://wordpress.org/support/topic/backwpup-ssh-failure/) * I am using backwpup to backup my wordpress databases using sftp. My wordpress site is running on an IONOS shared hosting server, which does not provide access to a command line. * When I attempt the backup, it fails. I an running an sftp server on oracle linux and when I look in the /var/log/secure file, which logs ssh errors, I see the following: * Feb 3 12:52:20 left-dell-t110 sshd[4175]: Invalid user user from 141.98.10.47 port 55422 Feb 3 12:52:20 left-dell-t110 sshd[4175]: pam_unix(sshd:auth): check pass; user unknown Feb 3 12:52:20 left-dell-t110 sshd[4175]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=141.98.10.47 Feb 3 12:52:23 left-dell-t110 sshd[4175]: Failed password for invalid user user from 141.98.10.47 port 55422 ssh2 Feb 3 12:52:25 left-dell-t110 sshd[4175]: Received disconnect from 141.98.10.47 port 55422:11: Normal Shutdown, Thank you for playing[ preauth] Feb 3 12:52:25 left-dell-t110 sshd[4175]: Disconnected from invalid user user 141.98.10.47 port 55422 [preauth] * The host on which wordpress is running is not 141.98.10.47, nor is this the address of the sftp machine. 141.98.10.47:55422 is sending a login request for the user“ user”, which seems like an error. There is a mysterious notation when 141.98.10.47 disconnects stipulating “Thank you for playing [preauth]”. I am not sure what“ preauth” means. * I have tried using both PHP 7.4 and PHP 8.0 and get the same results. * I have a screenshot of the FTP parameters, but there seems to be no way to attach it to this message - This topic was modified 4 years, 4 months ago by [dnessett](https://wordpress.org/support/users/dnessett/).

After poking around with Google, it appears the “preauth” activity is coming from bots trying to penetrate the system. I changed the port sshd listens on to 2200 and it went away. I am still not able, however, to save the database with BackWPup. I ran sshd in debug mode and here is the output: * Server listening on :: port 2200. debug1: Server will not fork when running in debugging mode. debug1: rexec start in 8 out 8 newsock 8 pipe -1 sock 11 debug1: inetd sockets after dupping: 4, 4 Connection from 74.208.xxx.yyy port 44128 on 192.168.1.54 port 2200 debug1: Local version string SSH-2.0-OpenSSH_8.0 kex_exchange_identification: Connection closed by remote host * sshd seems to accept a connection request from the server on which the wordpress site is running (74.208.xxx.yyy, where I have obscured the address using “xxx. yyy”). However, it then sits around and nothing happens. On the server side the output is: * [INFO] BackWPup 3.10.0; A project of Inpsyde GmbH [INFO] WordPress 5.8.3 on [https://test.mountolive.com/](https://test.mountolive.com/) [INFO] Log Level: Normal [INFO] BackWPup job: Daily Database Backup [INFO] Logfile is: backwpup_log_d6b910_2022- 02-04_11-49-53.html [INFO] Backup file is: 2022-02-04_11-49-53_VJN2B2OI01.zip[ 04-Feb-2022 11:49:53] 1.

I am not sure how to proceed to debug this problem, since the BackWPup side of things gives little information allowing me to make progress. There is an indication that Log Level can be changed, but I don’t know how to do that. * Thread Starter [dnessett](https://wordpress.org/support/users/dnessett/) * (@dnessett) * [4 years, 4 months ago](https://wordpress.org/support/topic/backwpup-ssh-failure/#post-15330728) * **Update** * The sftp server is behind a firewall. I was able to access it from outside the firewall using FileZilla. It is looking like there is something wrong with BackWPup, either a configuration problem or a bug. For completeness, I am including the FileZilla debug log in case that helps suggest what might be the problem. I have obscured the IP address for security purposes. * Status: Connecting to 184.167.xxx.yyy:2200… Trace: Going to execute /Applications/ FileZilla.app/Contents/MacOS/fzsftp Response: fzSftp started Trace: CSftpControlSocket:: ConnectParseResponse(fzSftp started) Trace: CSftpControlSocket::SendNextCommand() Trace: CSftpControlSocket::ConnectSend() Command: open “webserverbackup@184.167. xxx.yyy” 2200 Trace: Server version: SSH-2.0-OpenSSH_8.0 Trace: Using SSH protocol version 2 Trace: We claim version: SSH-2.0-PuTTY_Local:_Aug_28_2011_23:19:42 Trace: Using Diffie-Hellman with standard group “group14” Trace: Doing Diffie- Hellman key exchange with hash SHA-1 Command: Trust new Hostkey: Yes Trace: Host key fingerprint is: Trace: ssh-rsa 3072 77:59:29:52:3b:20:1e:6a:e8:bd:5c:09:b8: e6:84:ca Trace: Initialised AES-256 SDCTR client->server encryption Trace: Initialised HMAC-SHA1 client->server MAC algorithm Trace: Initialised AES-256 SDCTR server- >client encryption Trace: Initialised HMAC-SHA1 server->client MAC algorithm Trace: Pageant is running.

Please use FTP/FTPs or use other backup destinations, thank you! Thank you! * Thread Starter [dnessett](https://wordpress.org/support/users/dnessett/) * (@dnessett) * [4 years, 3 months ago](https://wordpress.org/support/topic/backwpup-ssh-failure/#post-15361074) * Thanks. I would like to use an S3 service running on our local cloud to store backups. I would like to configure the backups to use TLS encryption to protect the data as it travels over the internet. I am not enquiring about encrypting the files, which requires the BackWPup Pro version of the plugin, but rather encrypting the communication of those files. The files will be stored in plaintext on the local cloud. Does the backup plugin support this? * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [4 years, 3 months ago](https://wordpress.org/support/topic/backwpup-ssh-failure/#post-15367952) * [@dnessett](https://wordpress.org/support/users/dnessett/) you can try yourself with the S3 destination, BackWpUp allow you to do custom s3 ^^ I hope my answer could help Viewing 5 replies - 1 through 5 (of 5 total) The topic ‘BackWPup ssh failure’ is closed to new replies. * ![](https://ps.w.org/backwpup/assets/icon-256x256.png?rev=3236141) * [BackWPup – WordPress Backup & Restore Plugin](https://wordpress.org/plugins/backwpup/) * [Support Threads](https://wordpress.org/support/plugin/backwpup/) * [Active Topics](https://wordpress.org/support/plugin/backwpup/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/backwpup/unresolved/) * [Reviews](https://wordpress.org/support/plugin/backwpup/reviews/) * 5 replies * 2 participants * Last reply from: [happyAnt](https://wordpress.org/support/users/duongcuong96/) * Last activity: [4 years, 3 months ago](https://wordpress.org/support/topic/backwpup-ssh-failure/#post-15367952) * Status: resolved
