Where's the log file of SUSE?

[lung]

Dear All,

I want to know how to check the status of system(Server), I think the log will help me to know.
Could you please tell me how to check the status of server?

[Irithori]

Which status are you interested in?
You won´t find performance metrics.

In general, a daemon has its own logfile(s). They are usually in /var/log.
Other places might be defined in the daemon configs and/or (r)syslog

as above

tail -f /var/log/apache2/access_log
tail -f /var/log/apache2/error_log
tail -f /var/log/warn
tail -f /var/log/messages

are some of the most common logs to live-monitor during install or modification / problem solving

My friend told me check at /var/log/syslog for checking Hardware alarm but I didn't find the log file. What should I do?

[Irithori]

try /var/log/messages
and the command dmesg

[HossCartwright]

I tried the

tail -f /var/log/messages

For some reason I have to log in as superuser to run this. I thought I read somewhere that I should never be logged in as su while I am connected to the internet.

I am using SuSe 11.4. I am very new to Linux. I downloaded the SuSe 11.4 from the novell site, 60 day trial period. Can you point me to a reference on how to secure my new operating system? I feel naked online.

you are right, there are places, persons and sites making such recommendations about root
and because of too many ppl never using root in virtual world, all those ppl never learn to act responsibly and we have our global crisis ... because too many ppl doing without knowing because feeling protected by a government or insurance to avoid liability for mistakes

the www is a virtual world preparing for real world
here again is another more spiritual/philosophical approach to root vs user on a Linux system

how can a human learn to act responsible in real life, if he/she is scared to accept full liability and responsibility in a virtual world ?

Since 13+ yrs I strictly work as root - everywhere without any exception. if forces me TO FIRST KNOW wheat I do before I actually do id
just as we are expected to do in real life (high technology, etc) as well. first learn and know and then do
whatever you do

if you scared to work as root
then you can do as others being scared and use
sudo
to change from user to root for individual operations requiring root

If you always fully present, fully awake and never just trial and error as root
then you learn much faster to really know your system and optimize all your work

there are and will be other opinions
that's part of freedom of making own choice sin eternal life

Thank you all for your kindness
