Nginx client_ip in log file, with ssh -R Port forwarding

Hi, everyone!
First, I run a nginx server M1 (in my offce) behind a router R1 and M1's IP addr is 192.168.5.126. I set nginx's log format like this:
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
After that, I will get the correct client ip in the access log.
192.168.5.88 - - [21/Apr/2015:11:12:47 +0800] "GET /js/date.js HTTP/1.1" 200 403 "http://192.168.5.126/" "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.118 Safari/537.36" "-"
Then, I want to visit M1 outside (in the campus) . Unfortunately, I can do nothing with the router R1. But I have a router R2 whose framework is OpenWrt and its IP 222.xx.xx.xx can be visited by anyone who has logged into the campus network.
Then I wrote a autossh service to do that:
[Unit]
Description=AutoSSH service for local port 80 forwarded to 222.xx.xx.xx:80
# place this in /etc/systemd/system/, than enable this.
After=network.target
Requires=nginx.service
After=nginx.service
[Service]
Environment="AUTOSSH_GATETIME=0" "AUTOSSH_POLL=60" "AUTOSSH_LOGFILE=/var/log/nginxssh.log"
ExecStart=/usr/bin/autossh -M 22000 -NR 222.xx.xx.xx:808:localhost:808 -NR 222.xx.xx.xx:80:localhost:80 -o TCPKeepAlive=yes -p xxxx [email protected] -i /home/username/.ssh/id_rsa
[Install]
WantedBy=multi-user.target
Yeah, It works! BUT BUT when someone visits 222.xx.xx.xx, I lost the the client ip in nginx log file. That would always be 127.0.0.1, why?
127.0.0.1 - - [27/Apr/2015:00:34:07 +0800] "GET /static/mathjax/MathJax.js?config=TeX-AMS_HTML HTTP/1.1" 304 0 "http://222.xx.xx.xx:808/url/jakevdp.github.com/downloads/notebooks/XKCD_plots.ipynb" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:37.0) Gecko/20100101 Firefox/37.0" "-"
After ``ssh -R Port forwarding``, client ip is lost?
If so, what should I use to replace ``ssh -R``?

It seems there is a port forwarding configuration trouble with you modem.
When you access from the WAN or from the LAN, you don't enter in you modem the same way, so the behavior is different.
It seems that the port 22 of your modem is not directly forwarded to your server. The modem itself asks you a login/password. The key-pair authentification is between laptop and server. The modem itself is not recognized during this authentification.
Don't touch your ssh-config. It's OK since it was working for monthes before you change your modem.

Can't create log file with java.util.logging

Hi,
I have created a class to create a log file with java.util.logging
This class works correctly as standalone (without jdev/weblogic)
import java.io.IOException;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.*;
public class LogDemo
     private static final Logger logger = Logger.getLogger( "Logging" );
     public static void main( String[] args ) throws IOException
         Date date = new Date();
         DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
         String dateStr = dateFormat.format(date);
         String logFileName = dateStr + "SEC" + ".log";
         Handler fh;
         try
           fh = new FileHandler(logFileName);
           //fh.setFormatter(new XMLFormatter());
           fh.setFormatter(new SimpleFormatter());
           logger.addHandler(fh);
           logger.setLevel(Level.ALL);
           logger.log(Level.INFO, "Initialization log");
           // force a bug
           ((Object)null).toString();
         catch (IOException e)
              logger.log( Level.WARNING, e.getMessage(), e );
         catch (Exception e)
              logger.log( Level.WARNING, "Exception", e);
}But when I use this class...

public static void initLogger(String ApplicationName) {
    Date date = new Date();
    DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
    String dateStr = dateFormat.format(date);
    String logFileName = dateStr + ApplicationName + ".log";

      logger.setLevel(Level.ALL);
      logger.log(Level.INFO, "Initialization log");
    catch (IOException e)
      System.out.println(e.getMessage());
}and I call it in a backingBean, I have the message in console but the log file is not created.
TraceUtils.initLogger("SEC");why?
Thanks for your help.

I have uncommented this line in logging.properties and it works.
# To also add the FileHandler, use the following line instead.
handlers= java.util.logging.FileHandler, java.util.logging.ConsoleHandlerBut I have another problem:
jdev ignore the parameters of the FileHandler method .
And it creates a general log file with anothers log files created each time I call the method logp.
So I play with these parameters
fh = new FileHandler(logFileName,true);
fh = new FileHandler(logFileName,0,1,true);
fh = new FileHandler(logFileName,10000000,1,true);without succes.
I want only one log file, how to do that?

Do we need to format data and log files with 64k cluster size for sql server 2012?

Do we need to format data and log files with 64k cluster size for sql server 2012?
Does this best practice still applies to sql server 2012 & 2014?

Yes. The extent size of SQL Server data files, and the max log block size have not changed with the new versions, so the guidance should remain the same.

Getting empty log files with log4j and WebLogic 10.0

Hi!
I get empty log files with log4j 1.2.13 and WebLogic 10.0. If I don't run the application in the application server, then the logging works fine.
The properties file is located in a jar in the LIB folder of the deployed project. If I change the name of the log file name in the properties file, it just creates a new empty file.
What could be wrong?
Thanks!

I assume that when you change the name of the expected log file in the properties file, the new empty file is that name, correct?
That means you're at least getting that properties file loaded by log4j, which is a good sign.
As the file ends up empty, it appears that no logger statements are being executed at a debug level high enough for the current debug level. Can you throw in a logger.error() call at a point you're certain is executed?

OMBPlus: masking usernames / passwords in log files with ********?

Hi all,
Subjects says it: how to hide username and password in OMBPlus logs.
Any ideas...?
Br: Ykspisto

I don't use default OMB+ logging for this reason, plus I often want more robust logging. I also built a wrapper for executing OMB+ statements to simplify my exception handling in my main scripts. By catching both the return string from a statement as well as the exception strings, I keep full control over what gets logged.
HEre is the meat of my main library file:

}and I handle setting up the log file with a standard header at the top of each script, as illustrated here in a script I use to set up and register a location and control centers for when we build a new dev environment. Most of the referenced variables are held in a config script that we use to define our current working environment, which I am not attaching as the names are pretty descriptive I think.

Merging Log Files with same name

Hello,
I have log files with same name 00000000.jdb (because created at different machines). I would like to merge data stored in these two files.
I tried below approaches which do not work:
1. rename one of the files -> doesn't work as file header has file name info which doesn't match with renamed value
2. db dump/load -> dump and load works without error. (i have to dump Entity related Database and Format related Database -- from -l option) However when i try to read the file, it gives error.
Exception in thread "main" com.sleepycat.je.EnvironmentFailureException: (JE 5.0.103) Catalog could not be refreshed, may indicate corruption, errorFormatId=52 nFormats=51, . UNEXPECTED_EXCEPTION: Unexpected internal Exception, may have side effects.
I am using EntityStore and thus Annotated Entities.
Does any one has any insights?
Thanks.

Yuvaraj,
As you discovered, it is not possible to use .jdb files from one environment in a different environment. The .jdb files use an internal format with relationships between files that form the Btree.
I'm glad to hear you were able to use DbDump and DbLoad successfully.

Analzing log files with external tools?

Hi,
is there any way to use web analytics software like Webtrends with EP? In other words, does EP produce
an access log file with date, URL, user, referrer,
etc.?
Thanks in advance,
Stefan.

Thanks for the hint. Apparently httpaccess\responses.0.trc contains log entries that look very familiar to something an ordinary web server produces, which is good.
A simple perl script could transform the logfile (date, etc.) into a format that a Web statistics tool on the market (e.g. WebTrends) could use.
The SAP built-in reports are not something that drives a marketing department wild.
Thanks,
Stefan

One Log File With Tomcat

I am trying to figure out how to get all of my logging to use one log file. Currently when I start tomcat as a service it writes to stderr.log, stdout.log as well as a log file I have configured using Log4j. I would like all logs including startup/shutdown logs that are currently going to stdout.log/stderr.log to go to the file I write to using Log4j.
If I start tomcat using catalina.bat it doesn't do this (bc it writes to the console window) but I would like to send all those startup/shutdown messages to the log that Log4j uses if I start tomcat as a service.
Any help would be appreciated.

That doesn't really help, because I've got Log4j already running. It looks like there is no easy solution to this. I'm left with choosing one of the three options below.
1) Configure a <Logger> element for the Context that catches any logging not sent to the Log4j log file. This means I would have a stdout.log, stderr.log, log from the <Logger> element, and a log for Log4j. That's a lot of log files...
2) Not configure a <Logger> element for the Context. This means any logging not sent to the Log4j file will go to either stdout.log or stderr.log. Those files could get big and aren't rotated like my Log4j file. Not exactlly ideal either.
3) Don't install Tomcat through the .exe file. Unpackage it, set the environment variables, and set it up as a serivce through a script such as the one mentioned at http://weblogs.java.net/blog/simongbrown/archive/2003/09/installing_tomc.html setting the same file that Log4j uses for the -out and -err parameters. This means that all logging (startup/shutdown) will go to this one log file. But it also means messing with the install (deviating from the .exe) which scares me a little.
Unless someone has a better idea...I guess it's one of the three above.
Thanks,
Jim

Cannot Display Log File with Palm E2 and Palm Desktop 4.1.4.

I finally got the Palm Desktop 4.1.4 which works okay with Vista. I have the Palm Tungsten E2. When I sync, and when it indicates that there were some duplications, etc. and do I want to view the HTM log file, I click on view log, and it comes up unable to display/find the page! Does anyone know what is going on?
Post relates to: Tungsten E2
This question was solved.

Thanks for replying PALM_LOVER!
Sometimes, yes, sometimes no. When I first sync-ed today, I got the prompt, and when i clicked on VIEW LOG, it took me to a web page that said "FILE NOT FOUND "("Firefox can't find the file at /C:/Program Files/palmOne/Stephe/HotSyncLog.htm.") I re-sync-ed and did not get the prompt.

Create different log file with different schema by spool

Hello,
I want to know a way to create a different log file depend on different schema
I have two schema on same db server
1) schema kennam/*****/kennam
2) schema koonhey/*****/koonhey
by a way, I want to create a different log file name e.g. kennam.log / koonhey.log on such two schema...
I always run @showbalance; to run showbalance.sql to create that report..
I hope you understand what I talking about (english is not my native language........), anyone could help?
showbalancelog.sql
spool c:\log.log+
spool c:\log.log
select to_char(sysdate,'dd-mm-yyyy hh:mi:ss') from dual;
column com_name format a20;
select cus.tid, cus.com_name com_name, cus.com_balance,
NVL((select sum(invoice_total) from invoice where com_id=cus.tid),0) sum_invoice,
NVL((select sum(cheque_amount) from income where com_id=cus.tid),0) sum_income,
cus.com_balance -
NVL((select sum(invoice_total) from invoice where com_id=cus.tid),0) +
NVL((select sum(cheque_amount) from income where com_id=cus.tid),0) total_balance
from customers cus
order by cus.tid;
spool off

Need some help with ip camera port forwarding

Setting up a ip wireless security camera to provide internet access thru a airport extreme router. Using the free ip scanner software provided with the camera, I can see and connect to the camera on my own home network, wirelessly. I believe that port forwarding will give me access to the camera outside the local network. I'd like to be sure I am setting up the port forwarding correctly. Also if I decide to use back to my Mac in the future will this camera setup interfere with the settings?

OK I figured out how to Port forward and how to do DHCP reservations. Unfortunately the latest 5th Gen Airport extreme software has a bug and neither ip Cam would work. Rolling back the software on the Airport to a previous version finally allowed the DHCP reservations to work. But the port forwarding or something is not working. I can not log on to the ip cams remotely or wirelessly. I may have to borrow a different Wireless router from a IT friend and disconnect the Airport Extreme, to get the cams on wirelessly. Hopefully they fix the problem some day.

Can I append to IIS log files with jsp?

When we added a load balancer, our IIS logs started using its IP address in the logfile and not the client's real IP address.
I need to add the client's real address back into the IIS logs, so our
reports can restart having the correct session numbers.
Does anyone know how to do this in JSP?
I've found snippets of code that says it does this, but I'm not sure where to put the code.
<% Response.AppendToLog "client_IP" %>
I tried putting this in my .jsp file and it doesn't know about Response.
I find reference to Response in the asp API, but not in the jsp API.
AppendToLog appends this data to the URI Query field of the IIS Log.
We are using IIS5.0.

Hi Jonny,
I don't think it can be done the way you've suggested, however you can accomplish the same thing in a different way.
Go to System Preferences > Security > General and select 'Require Password Immediately after sleep or screensaver begins'
Then go into Energy Saver and set your Display sleep to 1 min OR go to Desktop and Screensaver and set the screensaver time to 3 mins.
That way, once your display goes to sleep or into screen saver it will require a password to resume. This will keep the music playing in the background and also has the added benefit of displaying iTunes album artwork as the screensaver (if that's the screensaver you have selected!)

Errors in the /users/unison/log/das.log file with "xitemid not unique".

When reviewing /users/unison/log/das.log it is showing errors with
"xitemid not unique":

DATE = Current date
PID = 12492
DEXOTEK ERRCODE Ox1800B -> ctldap_ItemGetById: ctldap_LDAPEntryGetById
DATE = Current date
PID = 12743
DEXOTEK ERRCODE Ox1800B -> ctldap_LDAPEntryGetById: xItemId not unique

Also, when comparing the das.log to the directory server access log matching
the timestamp from the error above, you may see errors such as the
following:
[23/Jun/1998:15:45:28 -0700] conn=37 op=66 SRCH base="o=Ace Industries,c=US" scope=2
filter="(nscalxitemid=10000:00257)"
[23/Jun/1998:15:45:28 -0700] conn=37 op=66 RESULT err=0 tag=101 nentries=1
[23/Jun/1998:15:45:28 -0700] conn=37 op=67 BIND dn="uid=nuser1,o=Ace Industries,c=US"

[23/Jun/1998:15:45:28 -0700] conn=37 op=68 SRCH base="o=Ace Industries,c=US" scope=2
filter="(nscalxitemid=10000:*)"
[23/Jun/1998:15:45:28 -0700] conn=37 op=68 RESULT err=4 tag=101 nentries=2
in which an err= 4 is LDAP SIZELIMIT EXCEEDED. This means that the search
resulted in multiple entries with the same ID, so the server does not
know which value to return.

These log entries might be due to duplicate or multiple nscalxitemid attributes
in a replicated directory server, i.e., each calendar enabled user and resource
is suppose to have a single, unique nscalxitemid attribute.

An example attribute entry in the LDAP database of user 00257 on
node 10000 would be:

nscalxitemid: 10000:00257

To identify these duplicate or multiple nscalxitemid attributes, use the new calendar
server tool, unidsdiff, which can be downloaded from
http://help.netscape.com/business/filelib.html#caltools.
