Is Ping enabled by default?

I have noted in several threads that people recommend turning off PING for battery life. I don't have restrictions enabled so I can't turn off PING without enabling restrictions which probably would be OK but I didn't care before.
I have not started PING in iTunes.
So does PING run on my phone because it isn't restricted even though off in iTunes?
Thanks

If you have not enabled ping in iTunes, that means it is not enabled on your phone.

Syslog not enabled by default in systemd setup

I installed Arch Linux from the 2012.10.6 iso, using systemd, and following the new, lengthy instructions. Made separate partitions for /var, /boot, and /home. Used btrfs on all of them. The system works fine, so far, except that most of the log files are missing. dmesg works. I intend this machine to be a server, so it has php-fpm and Apache, but not X Windows.
This is what I have in /var/log:
btmp faillog httpd/ journal/ lastlog old/ pacman.log php-fpm.log wtmp
Where is messages.log? Checking further, I found that the syslog (actually syslog-ng) service was never enabled. Soon as I activated syslog, messages.log and the rest of the usual files were created. Also, cron (cronie) was not enabled, which means no logrotate. Even if I missed something in the instructions, shouldn't syslog and cron be enabled by default?
Issues like this have me wondering if systemd is such a good idea. Making logging enabled by default ought to be easy enough to do, and shouldn't be a reason to back away from systemd. But systemd has other issues. It's Linux specific-- needs kernel features that are only in Linux. So it won't work with FreeBSD. From what I've read on LKML, the push towards systemd comes from the udev developers, who it seems are causing problems. udev was not supposed to depend on systemd, and now it will.

UDLD enable by default on version 122-31.SG

Hi,
[1] I would liket to confirm if UDLD is enabled by default on version 122-31.SG. I have 4506 equipments.
[2] What is the benefit of UDLD aggresive ? To my understanding the port will attempt to be up from error disable state 8 times. So is this good or bad ? ie) if the fiber is bad, then there is no use using the aggresive mode right ?
Thank you,
- sn -

Sanjay,
1. To answer your first question, it depends upon what kind of media and interface/global level.
UDLD global enable state - Globally disabled
UDLD per-interface enable state for fiber-optic media - Enabled on all Ethernet fiber-optic interfaces
UDLD per-interface enable state for twisted-pair (copper) media - Disabled on all Ethernet 10/100 and 1000BaseTX interfaces
Please refer the below URL for details:

Java Runtime parameters- setting trace/log levels and enabling by default

Hi,
I have a user reporting that a Java app that I support is unexpectedly quitting, and our developers are having trouble tracking down exactly what's causing the problem.
I'm trying to enable the maximum possible logging/tracing for this user, but I don't want to have to rely on them remembering to hit '5' on the console window to enable tracing on everything. Having read through the runtime documentation, I have added the following to my JRE runtime parameters:
-Xdebug -Djavaplugin.trace=true -Djavaplugin.trace.option=basic|net|security|ext|liveconnect -Djavaplugin.outputfiles.overwrite=falseHowever, I still get nothing in the log file until I manually hit '5' on the Java console, then everything I do after that gets added to the log.
Does anyone know how can I get the maximum logging/tracing enabled by default as soon as the JRE is loaded?

>>
-Xdebug -Djavaplugin.trace=true-Djavaplugin.trace.option=basic|net|security|ext|livec
onnect
-Djavaplugin.outputfiles.overwrite=false
One problem is that -Djavaplugin.trace.option=basic
OR net etc ... pick one of the options which are
separated with pipe symbols or use "all" without
quotes.
I'm having a similar problem with Java 6 - it seem
that nothing I put in the runtime parameters takes
effect. I had to edit
/home/USERNAME/.java/deployment/deployment.properties
and add deployment.trace=true.On second thought, I could be wrong about the trace options. I really don't know if you can combine options but I did see "all" somewhere.

Bird's Eye View enabled by default

Hi all,
is there a way to have the bird's eye view enabled by default in the impact/lineage? I need to enable it everytime i do a impact/lineage analyse. It takes to much time before it pops up.
I know it's something not very important :) But it's anoying...

Does Java has CLR checking enabled by default ?

Hi,
I have java application hosted on TOMCAT.
I have a custom socketFactory which uses JSSESocketFactory internally in my application. RSA is ending the “RSA Root Signing Service” shortly so wanted to know if CRL check is enabled or not for my application. I am not setting any CRL checking explicitly via my code. So just wanted to know if CRL checking is enabled by default in JAVA?
Thanks,

Apache got AddDefaultCharset enabled by default

Hello
Me and a co-worker has been working on a problem where a service of ours did not show the Swedish characters correctly.
It turned out that the AddDefaultCharset were enabled with 'UTF-8' by default in the Oracle-distro (altough the comments for the settings advised to only use it if neccesary).
We have fixed it now, by commenting out the setting again, but am wondering if this is a conscious choice or just something that slipped by, since it seem more likely to find the setting if in need then when hunting errors.
With best regards
Richard Knutsson

Mac OS X 10.8.2's firewall not enabled by default?

Hello.
Is it me or is Mountain Lion's firewall not enabled by default? I didn't check in the preinstalled 10.7.x before I upgraded to it. I find that weird and puzzled why Apple did that if that was by design.
Thank you in advance.

fowlerryan wrote:
Apple's firewall is disabled by default in mountain lion. I think this might be because of its new appl protection thing. Once the firewall is activated it will only open apps which are downloaded from the app store without questioning you. If you download an app from the web and have the firewall on, you will have to right click on the app and click open (for first time use only) to let the firewall know this is a safe app that you chose to download.
It may seem not having firewall on by default is silly but I think there would be far more complaints by people on here that they cant open their apps that they downlaoded from the web.
Hope it helps!

Sheesh, and Apple is trying to make our newer Mac OS X systems more vulnerable like Windows before it came with firewalls enabled.

Rationale for transparent_hugepage support being enabled by default?

So, my machine has always seemed to be a bit less responsive that it should be for the beefy 16G RAM, SSD, i7 quad core machine that is, but I could never really pinpoint why it was slow. Chrome/Chromium would always consume CPU and sometimes lead to stuttering(ie, periods of a few seconds consuming 100% CPU across all cores).. Or VMWare would just seem extremely slow with similar stuttering. And they were always linked somehow. When Chrome stuttered, all other applications worked fine, but VMWare completely froze until Chrome started responding again. And vice-versa.
While chasing down why Chome 38 made this issue about 500% worse (to the point that I was about to forget it and install firefox instead) I was looking in top and noticed that khugepaged would use quite a bit of CPU at the same time. I googled it on a whim and came across a magical pair of instructions:
echo madvise > /sys/kernel/mm/transparent_hugepage/enabled
echo madvise > /sys/kernel/mm/transparent_hugepage/defrag
Suddenly, instead of VMWare idling at around 30% at all times and Chrome processes idling at 2-3% each (not to mention horrible stuttering for both), now VMWare idled at around 5%, and Chrome processes weren't even on the map.
One of my friends tried this and suddenly he saw huge performance gains as well on an Ubuntu system.
I want to understand why this is enabled by default. I tried searching for it and found a few broad overviews of what it does.. but not why it's useful, and most of the results I see (including on this forum) are all suggestions to turn it off to improve performance or avoid kernel thrashing.
Can someone tell me what transparent_hugepage support is enabled for, what applications or workflows it might make better, and why for all the problems I see in search results, it's still enabled by default?

AFAIK, there are no security issues around Privacy Extensions... I assume you meant privacy.... If we are to patch for privacy, then we should disable javascript, cookies etc in all browsers in the official repos. That would be akin to patching for security, where we should set AllowRootLogin = no in sshd_config, and enable iptables to block all traffic by default.
Strike0 wrote:I see your points, but autoconf IPv6 addressing is one of those changes that should entail an informed opt-in IMO - at least at this time of adoption.
It's no different to connecting to a network and obtaining a DHCP lease, except more information is generated by your computer rather than a (possibly unknown/untrusted) network administrator
Strike0 wrote:Plus it is easy to change persistently.
Once you know how and what you're looking for, hence I thought it might be useful to have this thread.
Strike0 wrote:One way forward might be to add reasonably long TTL options for the temporary IPv6s in sysctl. Setting those to a time longer than the average reboot time might make away with side-effects and inefficiencies by multiple assigned temp IPs.
That could be a valid compromise in the situation. I would like to suggest setting the option to '1', but I'm not sure even what the point of this setting is since the kernel will prefer the stateless address for outgoing connections, the PE addresses would only be useful for incoming traffic, which is kind of pointless when the address will change within a very short lifetime (compared to an IPv4 address, or "static" stateless IPv6 address).

Any negative impact to having DEBUG enabled by default in PRODUCTION

Newbie to PL/SQL DEBUG, are there any downsides to having DEBUG enables by default for all packages in PRODUCTION?
Performance? Security Risk? Stability?

Usually you want debug on in an development environment and debug off in a production environment.
Main reason certainly is performance. I'm not aware of any major security issues. Although simply that those debug messages might include data is a little security hole by itself. For example: Some projects require that neither admin nor developer have access to the "real" data. This could be circumvented with debug messages.
You also might want to check out some white papers from http://www.oracle.com/technology/tech/pl_sql/index.html . Among others the [Conditional Compilation in Oracle Database 10g Release 2 (10.2) (PDF)|http://www.oracle.com/technology/tech/pl_sql/pdf/plsql_conditional_compilation.pdf] has some thoughts about the debug topic.

HT4794 Is DFS enabled by default on OSX Lion?

I am trying to connect SMB share on MAC OSX Lion but traces collected keep stating DFS is not supported.
-Saurabh

Well, after searching through CCO, this is what I found:
"Note On the Cisco 12000 series routers, dCEF is enabled by default. The command to enable dCEF is not available. Also, the configuration file does not indicate that dCEF is enabled on the router."
"Note CEF switching is not supported in GPRS Release 1.4 in Cisco IOS Release 12.2 and earlier. However, CEF is enabled by default. "
So I guess on some items it is enabled by default. Now I know :)

Is CEF enabled by default on some routers?

Sorry for the newbie question, but I was wondering if CEF is enabled by default on all routers, none, or just some (like high end routers).
Thanks

When will Shumway become enabled by default in Firefox?

I saw Shumway getting into Firefox recently, though it's disabled by default.
According to what I read - it seems like there's still quite a few miles to go through until Shumway can truely replace Adobe Flash Player's functionality.
When is it expected to be enabled by default in Firefox versions? (effectively replacing Adobe Flash Player for users)
I couldn't find an answer to this question in https://wiki.mozilla.org/Shumway

March 17th, 2014.
SEE: https://wiki.mozilla.org/RapidRelease/Calendar
Also, heres the proof that it is aimed to release Firefox 28.
