Open. SSHLogging and Troubleshooting Wikibooks, open books for an open world. Both the Open. SSH client and server offer a lot of choice as to where the logs are written and how much information is collected. A prerequisite for logging is having an accurate system clock using the Network Time Protocol, NTP, which provides time synchronization with rest of the world. The more accurate the time stamp in the log is, the faster it is to coordinate forensics between machines or sites or service providers. If you have to contact outside parties like a service provider, progress can usually only be made with very exact times. Server LogseditBy default sshd8 sends logging information to the system logs using the log level INFO and the system log facility AUTH. So the place to look for log data from sshd8 is in varlogauth.

In most cases the default level of logging is fine, but during initial testing of new services or activities it is sometimes necessary to have more information. Debugging info usually goes to stderr. Starting with Open. SSH 7. 6, Match blocks can set alternate log levels for specific conditions. The log excerpt below show the same basic server start up with increased detail.

Every failed login attempt is recorded, once the value in directive Max. Razorsql Serial Number more. Auth. Tries is exceeded the connection is broken. Below is a log excerpt showing how the default log looks after some failed attempts. Mar 1. 9 1. 1 1. Failed password for root from 1. Mar 1. 9 1. 1 1. Failed password for root from 1. Mar 1. 9 1. 1 1. Failed password for root from 1. Mar 1. 9 1. 1 1. Failed password for root from 1. Mar 1. 9 1. 1 1. Failed password for root from 1. Mar 1. 9 1. 1 1. Mar 1. Disconnecting authenticating user root 1. Too many authentication failures preauth. It is usually a good idea not to allow root login. That simplifies log analysis greatly. It in particular eliminates the time consuming question of who is trying to get in and why. Tasks that need root level access can be given it through custom made entries in etcsudoers. People that need root level access can gain it through su or, for specific programs, via sudo. Successful loginseditBy default, the server does not store much information about user transactions. That is a good thing. It is also a good thing to recognize when the system is operating as it should. So here is an example of a successful SSH login. Mar 1. 4 1. 9 5. Accepted password for fred from 1. And here is an example using a key for authentication. It shows the kewy fingerprint as a SHA2. Mar 1. 4 1. 9 5. Accepted publickey for fred from 1.

RSA e. 8 3. 1 6. In older versions of Open. SSH, prior to 6. 3, the key fingerprint is completely missing from authentication logging. Jan 2. 8 1. 1 5. Accepted publickey for fred from 1. Here is an example of password authentication for an SFTP session, using the servers internal sftp subsystem. The logging for that subsystem set to INFO. Mar 1. 4 2. 0 1. Accepted password for fred from 1. Mar 1. 4 2. 0 1. Here is an example of a successful SFTP login using an RSA key for authentication. Mar 1. 4 2. 0 2. Accepted publickey for fred from 1. RSA SHA2. 56 LITSnwo. Lryu. Yis. An. NEIed. VBXwlXsr. Xjli. 9Qw. Smw. I. Mar 1. 4 2. Additional data, such as connection duration, can be logged with the help of xinetd. Logging SFTP File TransferseditSFTP file transfers can be logged using Log. Level INFO or VERBOSE. The log level for the SFTP server can be set in sshdconfig5 separately from the general SSH server settings. Subsystem internal sftp l INFO. By default the SFTP messages will also end up in auth. Sometimes this is done by changing the log facility code from the default of AUTH. Available options are LOCAL0 through LOCAL7, plus, less usefully, DAEMON and USER. Subsystem internal sftp l INFO f LOCAL6. If new system log files are assigned, it is important to remember them in log rotation, too. Again, the Match directive can be use to change the log level for certain connections. The following log excerpts are generated from using the log level INFO. A session starts with an open and end with a close. The number in the brackets is the process id for the SFTP session and is the only way to follow a session through the logs. Oct 2. 2 1. 1 5. Oct 2. Here is an SFTP upload of a small file of 9. Oct 2. 2 1. 1 5. WRITE,CREATE,TRUNCATE mode 0. Oct 2. 2 1. 1 5. And a directory listing in the same session in the directory varwww. Oct 2. 2 1. 2 0. Oct 2. And lastly here is a download of the same small 9. Oct 2. 2 1. 2 0. READ mode 0. Oct 2. 2 1. 2 0. Successful transfers will be noted by a close message. Attempts to download open files that do not exist will be followed by a sent status No such file message on a line of its own instead of a close. Files that exist but that the user is not allowed to read will create a sent status Permission denied message. Logging Chrooted SFTPeditLogging with the built in sftp subsystem inside a chroot jail, defined by Chroot. Directory, needs a. This can be done by having the system logger such as syslogd8 add additional log sockets inside the chrooted directory when starting up. On some systems that is as simple as adding more flags, like u a chrootdevlog, in etcrc. Here is an example of an SFTP login with password to a chroot jail using log level DEBUG3 for the SFTP subsystem. The log shows a file upload. Jan 2. 8 1. 2 4. Connection from 1. Jan 2. 8 1. 2 4. Failed none for fred from 1. Jan 2. 8 1. 2 4. Accepted password for fred from 1. Jan 2. 8 1. 2 4. User child is on pid 2. Jan 2. 8 1. 2 4. Changed root directory to homefred. Jan 2. 8 1. 2 4. Jan 2.
