Scott's questions

We have a rather strict policy regarding our subversion repository that is also a large inconvenience. With our branches, anything that gets checked into subversion has to have redacted authentication credentials (e.g. database, user accounts, etc...). A file was added and committed with both names and passwords. There exists three revisions of this xml file:

First - File was added and committed with some irrelevant (to this question) content.
Second - File (among 3 other irrelevant files) was committed with authentication credentials as part of an entirely new block of XML.
Third - More files were added and checked in, none being newer versions of the bad file from the previous revision.
Fourth - Single bad file was checked in again with the authentication credentials (specifically, nothing else) removed.

I'd like to remove the second revision, and being that this is the first occurrence of this occurring, I've never had to deal with this before. I know it's difficult with subversion, as the intent of the software is to maintain your code revisions, not pick away and make changes to old revisions. Is this possible to delete one file from a previous revision, or overwrite it with the contents of a newer revision (i.e. replace the bad file from the second revision with the file from the fourth)?

I arrived at work today to find that tomcat6 won't start. When trying to stop and start with the following command(s):

 service tomcat6 stop ; > /var/log/tomcat6/catalina.out && service tomcat6 start && less +F /var/log/tomcat6/catalina.out

It reports back OK for starting tomcat, but using ps, no tomcat process is shown. The catalina.out file doesn't show anything at all either, completely blank. Upon looking at /var/log/tomcat6/tomcat6-initd.log, I see two lines repeated over and over on every attempt:

/usr/sbin/tomcat6: line 60: ${2}: ambiguous redirect
/usr/sbin/tomcat6: line 30: ${2}: ambiguous redirect

Looking at /usr/sbin/tomcat6, both lines read:

${JAVACMD} $JAVA_OPTS $CATALINA_OPTS \
  -classpath "$CLASSPATH" \
  -Dcatalina.base="$CATALINA_BASE" \
  -Dcatalina.home="$CATALINA_HOME" \
  -Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" \
  -Djava.io.tmpdir="$CATALINA_TMPDIR" \
  -Djava.util.logging.config.file="${CATALINA_BASE}/conf/logging.properties" \
  -Djava.util.logging.manager="org.apache.juli.ClassLoaderLogManager" \
  org.apache.catalina.startup.Bootstrap start \
   >> ${2} 2>&1 &

The first line being the same for both 60 & 30. My $JAVA_OPTS reads:

JAVA_OPTS="-server -Xss128K -Xms3G -Xmx3G -XX:MaxPermSize=256M -Dambiguous.url=https://ambiguous.url.com"

and so far as I can tell (uncertain where to look, honestly), $CATALINA_OPTS is null, but I could be mistaken. One things for certain, I haven't adjusted its value, and am confident that the value has nothing to do with the ambiguous redirect issues.

UPDATE: By updating our tomcat6 package to the latest version, I now do not receive the errors seen above. In fact, the /usr/sbin/tomcat6 file reads entirely different around the areas it was pointing me to before:

  ${JAVACMD} $JAVA_OPTS $CATALINA_OPTS \
    -classpath "$CLASSPATH" \
    -Dcatalina.base="$CATALINA_BASE" \
    -Dcatalina.home="$CATALINA_HOME" \
    -Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" \
    -Djava.io.tmpdir="$CATALINA_TMPDIR" \
    -Djava.util.logging.config.file="${CATALINA_BASE}/conf/logging.properties" \
    -Djava.util.logging.manager="org.apache.juli.ClassLoaderLogManager" \
    org.apache.catalina.startup.Bootstrap start \
    >> ${CATALINA_BASE}/logs/catalina.out 2>&1 &
    if [ ! -z "$CATALINA_PID" ]; then
      echo $! > $CATALINA_PID
    fi

Now it gets even more complicated, as tomcat6-initd.log does not report anything at all, yet the service still doesn't start up. Running the init script with a -x results in the following output on startup:

# service tomcat6 start
+ '[' -r /lib/lsb/init-functions ']'

+ '[' Scientific = MandrivaLinux ']'
+ RETVAL=0
+ return
+ exit 0

If I were to run the exact same setup on a separate server where tomcat works (there's multiple virtual machines running as a cluster), the output reads:

And just to be thorough, the start() function in /etc/init.d/tomcat6 reads:

Unfortunately the software that I'm using (Alfresco) requires the installation of openoffice, and not libreoffice. If I try and configure it to use libreoffice I receive errors during startup. If I try to install any of the openoffice packages:

yum install openoffice*

I receive errors for all packages similar to:

Package openoffice.org-langpack-bg_BG is obsoleted by libreoffice-langpack-bg, trying to install 1:libreoffice-langpack-bg-3.4.5.2-16.el6.x86_64 instead

Then it proceeds to try and download libreoffice. I don't see anything in man yum with regards to installing obsolete packages. Is there any way to install obsolete packages via yum and not their newer counterparts?

On a basic LAMP stack, at least with our RHEL5/6 servers, we are able to apply rolling code-updates to our document management system across load-balanced web servers without killing users' connections (and possibly document downloads) by using apachectl graceful and apachectl graceful-stop. We're migrating to a Tomcat web server based application, and we'd like to have that sort of capability with our new system, but I cannot find any sort of equivalent functionality with tomcat6. Does such a capability exist with tomcat6?

We're running an application on RHEL and it is trying to write a mysterious log file to a directory that doesn't exist. I'm trying to determine a find command that could go through each sub-directory in development and mkdir log without creating a recursive indefinite loop in the process. So if my folder structure from a very basic redacted view was similar to:

-dir1
--dir11
--dir12
-dir2
--dir21
--dir22
-dir3
--dir31
--dir32

I would want the end result to be

-dir1
--dir11
---log
--dir12
---log
--log
-dir2
--dir21
---log
--dir22
---log
--log
-dir3
--dir31
---log
--dir32
---log
--log

what bash command could create this structure?

I'm currently running Xubuntu on my netbook, and I'd like to get all port 80 traffic running through an SSH tunnel, regardless of whether I set it in the browser or not. Chromium uses your operating system's proxy information, and will not work in linux for whatever reason, thus it is not as easy as setting the socks proxy. I can set up an SSH tunnel for other browsers such as Firefox, but I can't for Chromium. There are other ports I'd like to tunnel as well (pidgin for example), but I won't get into those quite yet. Is there a way to take all port 80 traffic and pre-route it through iptables first, which would then forward it through my SSH tunnel, and onto its destination?

I am parsing my httpd access logs, to grab out which of our Google appliance's crawlers are bombarding my web servers, and when. If I type the command:

grep google /path/to/access_log | awk '{print $4, $14}'

I can get a very large (like I said, they're bombarding me) return set, at least 4 per second. I want to be able to group the above listed result set by the time stamp, and return a string inline with the number of hits there were per second. So ideally, I'd like to have something similar to

04/Aug/2011:15:56:16 Crawler1 6
04/Aug/2011:15:56:16 Crawler2 10
04/Aug/2011:15:56:17 Crawler1 8
04/Aug/2011:15:56:18 Crawler1 12

Where the first is the timestamp, second is the 14th field, the Google Crawler's ID, and third being the count. The order of the columns is irrelevant.

I would like to install a batch of openoffice.org-* packages from the yum repository. The catch is that I want to exclude the dozens of openoffice.org-langpack* files when I do it. I also don't want to have to run two commands (i.e. yum install openoffice.org-*;yum remove openoffice.org-lang*). I've attempted to run the command yum install openoffice.org-[^l].* without any luck, as it looks for a package labeled exactly as typed. What command can I run to achieve this?
