I am currently using Syslog-NG to make the log files in the format of: $R_YEAR$R_MONTH$R_DAY$R_HOUR and I need to be a little more granular.
I am wondering if there is a way to to divide the hour by 12, making a new log file every 5 minutes. We have been using LogRotate, but when Syslog-NG is restarted we have some data loss. Is this possible? Another solution I can think of would be to add $R_MINUTE (or whatever it is) and run a cron job every 5 minutes to concatenate the files.
I noticed in my system that my root partition is getting full. I found a lot of old compacted syslogfiles. Had a look at etc/sysconfig editor eg cron but could not find a setting which allows to delete files older than a month. Where and how could I influence this ? I deleted manually all syslog files older than a month. Approx 6GB
Can syslog be used to "watch" other log-Files from other software? I would like to get an info in messages if a logfile of squid is changed/something is added.
In my system, I see two syslog configuration files, /etc/rsyslog.conf and /etc/syslog.conf.. What is the use of each file? I know only that of /etc/syslog.conf...how about /etc/rsyslog.conf? what is its use?
I am looking for an open source syslog server which accumulate the each and every log of Windows, Solaris, Linux and network devices. Currently I am using Syslog-ng which is not fulfiling my requirement in Windows clients, as I need the logs of every action which user performed after logon.
I wanted to make a SysLog Server in Ubuntu 10.04 Desktop to collect the startup log of all the workstation inside the local area network,which should have a similar functionality to this guide here:Debian Syslog Server..However, when editing the sysklogd, i noticed it was empty and does not have any default values, along with the /etc/syslog.conf, which does not also exist.
I have a 60GB partition with / and home on it. I logged on yesterday and it gave me a warning saying that I had only 1.9 GB of disk space left. I ignored it for a day and assumed that i had too many videos and pics.But the next day i had not added any files or downloaded any software but i had 0B left. I used the disk usage analyser and found that 33GBs came from /var/log. It was from two log files. syslog and daemon.log 16.5GB each!! I opened them up and i found that this line of text was repeated hnundreds of thousands of times.

Syslog is used to store simple log files or we can manage them too? Well, the thing is, that I need to run a software (like syslog) to collect my logs and put them in order and organize them so it makes them "understandable". I have been told that syslog can do the job and that it doesn't need a complex configuration to work.
wants to remove everything else that (presumably) has syslog as a dependency. how do I replace the dependency on syslog with a dependency on syslog-ng?
Im trying to get syslog-ng to log ssh stuff to a own file (later i want it to be forwarded to a other server but thats a later problem.
The thing is that if i restart my syslog-ng server and login with ssh, it logs it. but when i login again it dont. But if i restart the syslog-ng daemon again it logs again, but only once.
I have an ubuntu (8.04.3) server where I use bacula to make backups of the files stored on the server. Ive been trying to find a solution (with no luck) trying to succesfully implement the following:-
A Backup tape for each day of the week besides Thurs which is resused on a weekly basis. For the thursday tapes we have a backup tape corresponding to the week number that the thursday falls so for the first thursday of the month it would be ThursOne For example. These tapes are resued on a monthly basis. We then have a monthly tape that is used on the last thursday of the month. These tapes will be resused on a yearly basis.
Another requirement is just in case a tape is accidently not changed a backup should still occur regardless of what tape is in the drive (so if its tuesday and mondays tape is still in the tape drive it should rewrite that tape).
I did have this successfully set up where the tape was appended after each use rather than being recycled after the nightly backup. But then after a few weeks I would have to manually purge tapes when they became full (which isnt ideal - as Im not always in the office so in my absence it may be that a backup may not take place), so have been playing around and have now got the tapes to be marked as used after a max of 2 jobs (so the backup of the files and the catalog of the night). I also added this line 'Recycle Current Volume = yes' so that it would hopefully recycle the volume in the drive.
However what I am finding is that the tape that should be recycled is not, but in yesterday case the Mondays tape was recycled rather than the Tuesday although Mondays was the last written so Im not even sure why it choose to recycle this tape.
I tried to install Syslog-ng-3.2.4 in Centos 5.6,when i need to start the deamon syslog-ng =>Failure and i have this message:
Code: [root@RelaisXXX etc]# service syslog-ng start Starting syslog-ng: Your configuration file uses an obsoleted keyword, please up Your configuration file uses an obsoleted keyword, please update your configurat Error creating persistent state file; filename='/usr/local/var/syslog-ng.persist Starting Kernel Logger [FAILED]:
I�m installing fail2ban to improve the security of a home asterisk server which from time to time becomes the target of some sip account cracker and/or ssh brute force attack.For those not familiar with fail2ban, this utility monitors log files to find matches with user specified expressions to identify the presence of a brute force attack. Then configures iptables rules to block the offending IP.Here�s an example:
Code: NOTICE[1734] chan_sip.c: Registration from '"613"<sip:613@xx.xxxx.xxx.xxx>' failed for 'yyy.yyy.yyyy.yyy' - No matching peer found
I'm guessing its possible but I can't seem to find any documentation on how to do this.I've tried playing with entries at the top of my syslog.conf file like:
*.* @172.20.10.1 # 1 server, works file *.* @172.20.10.1,172.20.20.11 # doesn't work *.* @172.20.10.1 172.20.20.11 # nor this *.* @172.20.10.1,@172.20.20.11 # nor this *.* @172.20.10.1 @172.20.20.11 # nor this
I open "man vsftpd.conf", it says syslog_enable If enabled, then any log output which would have gone o /var/log/vsftpd.log goes to the system log instead. Logging is done under the FTPD facility. Default: NO So I add "syslog_enable=YES" to the /etc/vsftpd.conf, and add "ftpd.* /var/log/ftplog" into /etc/syslog.conf. But there is no log infomation in the ftplog file.
I would expect this behavior if "domain.com and anotherdomain.com" wasn't a domain that I hosted. But this is a valid domain that this server should be answering for. In my named.conf I do have the
Quote:
allow-query { any; };
option on every zone. This is my slave server and I have the primary shut off so I can test this slave server. FYI: So far queriers still seem to be working. The pages for the sites are still coming up via the internet.
We have several SLES, CentOS, Fedora server and use logmail to filter the logs on our central syslog-Server. The problem is, that the filtering take more and more time and the configuration gets more and more confusing. What program to use to analyse our central logfile? Something mysql based?
I am facing an issue with my syslog server. The server is collecting remote log also. and the issue is no log messages are updated in /var/log/messages file. But other files are getting updated.
[root@Server1 ~]# cat /etc/syslog.conf # Log all kernel messages to the console. # Logging much else clutters up the screen.
Syslog stops writing immediately after log rotation, after I start the system (but not after reboot), and at some other times, into my fast cgi application's log. It starts working after /etc/init.d/sysklogd restart.
Configuration:
I am using Ubuntu 8.04 lts server, Apache web server.
I have a dual-processor x86 box with CentOS 5 Linux 2.6.18-238.19.1.el5, mysql Ver 14.12 Distrib 5.0.77, and tons of storage space. I want to run a syslog solution on this box for a SOHO infrastructure. We've got routers, switches, Windows servers, other Linux boxes, etc. I've looked at syslog-ng, but it seems rather overkill, but I like the idea of storing logs in a MySql database. Is there anything I can yum install?
How do clients handle offline syslog servers?Will the log files be buffered locally to be sent to the syslog server when it comes back online, or will any log data generated during downtime be lost in cyber space?
RHEL 5.4 i want to be able to do redistribution of inbound syslog messages to syslogd. as example, my syslog.conf has in it at the end:
*.* @192.168.5.5 *.* @192.168.5.6
my sysconfig/syslog file has "-r" as the only option for syslogd. any messages generated by the localhost will be sent to the two remote servers, but messages that come into this box (udp 514) only get logged locally and do not get sent out to the remote hosts.
you may ask why do i want to do this. because i have several syslog servers (for security purposes) and many of my net devices are configured to send syslog to all the syslog servers, hence each device is sending way too much duplicate udp-514. so i would like to minimize the udp-514 coming out of the devices, have all devices send to a central syslog server, and then central syslog server do distribution to the other syslog servers. others have also called this "syslog proxy". or, if not with syslogd, how to achieve this (preserving the original syslog message host info, etc)?
