Andy Madge's questions

When running the silent uninstall command:

"C:\Program Files\Apache Software Foundation\Tomcat 8.5\Uninstall.exe" /S -ServiceName="Tomcat8"

Tomcat is uninstalled but it leaves behind a bunch of files in the conf, logs and webapps folders.

When uninstalling via Windows Program & Features, the GUI uninstaller shows a prompt asking whether to delete these extra files/folders.

Is there an argument/option that will delete these files with the silent uninstall?

I've looked through the Tomcat docs but there is no mention of the silent uninstall. I've even looked through the Tomcat source code, but I can't find any clues.

This page suggests that Tomcat uses NSIS Installer but the docs aren't helpful.

I'm trying to find the answer for both Tomcat 8.5 and 7.0 if possible.

A bit of background

I have a server with 3 IP addresses and 3 <Host> elements defined in the server.xml. I'm using IP-based virtual hosts.

I have enabled the Access Log Valve on each Host, logging to 3 different log files.

It's working correctly, and I can see the requests logged to the correct files depending on which IP I hit.

So far, so good.

Now I'm trying to diagnose a load balancer issue, so I need to see the IP that each incoming request is hitting.

My actual question

According to the docs if you include %A in the access log pattern it should record the "Local IP address".

eg. pattern="%h %A %l %u %t "%r" %s %b"

However, what I'm seeing is requests hitting any of the 3 virtual hosts all show the same Local IP (ie. all 3 logs files show the same Local IP for all requests)

I would expect to see a different Local IP in each log. I know for certain they have arrived on different IPs, because that's how IP-based virtual hosts works.

I wonder if %A is just outputting what Tomcat thinks it's IP address is, rather than it actually being the IP the request arrived on.

Is it possible to log the actual IP each request came in on? Is there a different attribute I should use?

Additional info

Server has 3 IPs and hosts file contains:

10.10.10.10   localhost
10.10.10.1    serverA
10.10.10.2    serverB

My server.xml contains:

<Connector port="80" protocol="HTTP/1.1"
        connectionTimeout="20000"
        redirectPort="443" server="Unknown"
        useIPVHosts="true" />
...
<engine>
    <Host name="localhost" appBase="C:\webapps" unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log." suffix=".txt" pattern="%h %A %l %u %t &quot;%r&quot; %s %b"/>
    </Host>

    <Host name="serverA" appBase="D:\webapps\app01">
        <Context path="/myapp" docBase="D:\webapps\app01" />
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="serverA_access_log." suffix=".txt" pattern="%h %A %l %u %t &quot;%r&quot; %s %b"/>
    </Host>

    <Host name="serverB" appBase="D:\webapps\app02">
        <Context path="/myapp" docBase="D:\webapps\app02" />
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="serverB_access_log." suffix=".txt" pattern="%h %A %l %u %t &quot;%r&quot; %s %b"/>
    </Host>
</engine>

I have a long list of IP addresses I need to add as allowed relays to the built-in SMTP service on Windows Server 2008 R2 (IIS 7.5, but SMTP uses the old IIS 6.0 manager)

I know how to add allowed relays manually, but there is quite a long list so I'm looking to automate it.

Is there any way to do this from the command line, a script or some other automation?

I need to disable updates for a particular host but I want to keep the graphs for historical data.

I've tried using update no on the host definition in munin.conf but that removes the host from the overview etc. This isn't quite what I was expecting based on the docs.

The HTML and images are (obviously) still there in /var/www/html/munin and I can still load the URL manually, but I'd like it to be listed in the overview.

Can anyone clarify the differences between the --checksum and --ignore-times options of rsync?

My understanding is as follows:

--checksum
If the file size and time match, it will do a checksum at both ends to see if the files are really identical.

--ignore-times
'Transfer' every file, regardless of whether file time is same at both ends. Since it will still use the delta-transfer algorithm, if a file actually is identical, nothing gets transferred.

That's the technical difference, but as far as I can tell, they are semantically the same thing.

So, what I'm wondering is:

• What is the practical difference between the two options?
• In what cases would you use one rather than the other?
• Is there any performance difference between them?
