The other thing to note is that if you feel the machine generating logs is unreliable, or insecure, it might be better to have the log-storing host copy from the log generating machine than give it permission to write to the remote machine. For instance, it can copy files and directories in a file system drive and. If the goal is to have access to the logs from the last 5 minutes (eg for OSSEC), then the above transfer methods are better.
NFS (or Ceph/GlusterFS/SMBFS) mount one machine's directory onto the other, and do a continuous tail onto the other machine.ĭepending on your goal for transferring the logs, you can be more efficient by including the transfer in the post-rotate of logrotate if the goal is to store them long term on a bigger disk. This should be gentler on SSDs and avoids dirtying kernel IO buffers, but it is still incurring IO ops to scan the beginning at both ends.). To copy files from or to remote directories requires an IP address or a domain name. However seems that synch does not copy the files present from local directory. 3) in the central server run chmod and change rights (i.e. 2) in the central server create a file /var/log//rsyslog.log. 1) in the central server create a folder for client messages under /var/log/. #LINUX COPY LOG DIRECTORY TO REMOTE HOST ARCHIVE#
a, archive archive files and directory while synchronizing ( -a equal to following options -rlptgoD) -r. 1) in the client try to ping the central server to assure that connection really works. Some of the commonly used options in rsync command are listed below: -v, verbose Verbose output.
I prefer to use this module instead of the copy module to get better performance for large file transfer. Remote Sync Push: rsync :. Rsync ~/my_log_file.txt with cron you can save recopying the first part of the log file (I express uncertainty since you definitely save COPYING the already transferred portion, but you still do a comparison on each side to locate the already transferred portion to skip. The Rsync tool is required on both machines. Im trying to test synchronize module in order to copy the content from a local directory on remote host.
Alternatively, I think if you use rsync. Then at the remote end you need to setup the receiving server to filter the remote messages into the appropriate place (by sending host with %HOSTNAME% as part of file name, by facility %syslogfacility-text%, program name %programname%, etc.) The part about sorting things out at the other end is specific to rsyslog.) For the purposes of this article, I'll refer to that remote system. The next step is to copy the idrsa.pub file to the remote server you want to be able to access with ssh and/or scp without using a password. My preferred method as suggested by ryekayo is to just send the syslog messages to local file AND to remote host:Īuthpriv.* part of the facility I think works with pretty much all syslog daemons. Step 2: Copy your public key to your remote servers.
