Cisco SA520 - Unable to block all torrents and Poor Performance

Hi, I have installed a Cisco SA520W Appliance at a Client who has about 40-50 PC's, the device has the latest firmware 2.1.7 and latest IPS signature (17) installed, the client is quite disappointed about the performance of the device as he believes Internet browsing access has slowed down substantially.
The main problem the client is encountering is that, he is unable to block Utorrent P2P software and this is not allowing him to retain Internet control from the SA520 appliance.
He had also commented on the fact that there does not appear to be a status monitor on IP usage of Internet access to pinpoint who at that time would be hogging up the bandwidth.
Any feedback, same encounters scenarios and possible fixes to the above issues would be appreciated.
Thanks
Shawn

You might find this thread interesting regarding the router's performance with IPS turned on. An SA540, and an access point, would yield slightly better performance. That's what we use.
https://supportforums.cisco.com/thread/2022832?tstart=60
There are some older threads regarding the SA500 series router's ability to detect torrent activity. You might want to dig them up and respond to them. The Cisco folks were working diligently at optimizing the IPS engine's ability to detect different types of torrent activity.
There is no way to monitor Internet access usage at the individual IP level that I am aware of. I suggest turning on network logging (to a syslog server as there will be a lot of data to capture) and monitor traffic that way. Kiwi Syslog Server has a free version that your client could use.

I ignored this for sometime but today I lost my patience and decided to fix this nagging problem. The update prevented me from using the shutdown option as then it would download the updates and then fail over and over again.
None of the steps helped however they set me on a path. I uninstalled all unwanted programs but that was not what fixed the issue. I noticed other than Office 2007 I also had installed Word viewer 2007 , Excel viewer, Powerpoint viewer. I uninstalled these
voila!! Windows update said I don't need these updates on which the install was failing, I checked for updates again and the above updates never appeared in the list of updates found.
I thought I will put this out there just incase someone else runs into similar situation as me. Good Luck.

Safari hangs and poor performance in MBPR (Mid 2012)

Safari hangs and poor performance in MBPR (Mid 2012)? OS X 10.10.2 is up to date

Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
Back up all data before making any changes.
Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.
If your browser is Safari, then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. If the Downloads button (with the icon of a downward-pointing arrow) is showing in the toolbar, click it and then click Clear in the box that appears. The download history will be removed. Any change?
If you're running OS X 10.9 or later, select the Advanced tab in the Preferences window and uncheck the box marked
Stop plug-ins to save power
Any change?
Quit and relaunch the browser. Any change?
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
If Parental Controls is active for any user, please turn it off and test. Any change?
If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
Follow the instructions in this support article. Any change?
Open the iCloud preference pane and uncheck the box marked Photos, if it's checked. Any change?
Are there any other devices on the same network that can browse the Web, and are they affected?
If you can test Safari on another network, is it the same there?
If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

Blocking Bit-Torrent and other P2P softwares

Hello Dear All
I need to block All P2P Activity (ASA 5525) from VPN Users (outside), I tried some access lists, but they didn't take any action.
could you please assist me the access lists/policy-maps that you have done before and its working.
As you see output of service-policy there are matching but there is no any packet dropped.

Thank You

Hi Ali,
Your VPN users connects through internet and get internet access from the ASA connected internet link??? There you want to block the bit torrent and P2P?? Please describe your setup....
Also provide your configurations that is related to P2P & Bit Torrent blocking
Remember one thing.
The ASA can block P2P type applications only if P2P traffic is being tunneled through HTTP. Also, ASA can drop P2P traffic if it is tunneled through HTTP. If that is already been proxied then its not poosible for asa to block such traffic.

Invalid block count and poor performance

Hi - Can anyone help?
Running an early 2011 13' MBP on ML. For a year - 18 months I've noticed poor performance at times, consistently slow boot (sometimes 5 minutes to usable), occasional lockups and spotlight often reindexes itself and slows the system (much more than my previous MBP), I can't see anything that triggers it. I'm also getting recurring errors in Disk Utility of 'Invalid block count', every time I'll repair the disk (booting into recovery), but after a month of use the error will reappear. About three months ago I erased and reinstalled ML, some of my data was moved over in Time Machine but I didn't restore from it. The erase and reinstall hasn't made any difference and I'm still seeing the same issues. Hard disk SMART status appears to be fine.
Can anyone recommend any troubleshooting steps? I'm not sure what else to do, still under Applecare and was thinking maybe the HD isn't working correctly?
Cheers!

Best way to handle all erros and get performance(OCI)?

Hi there,
Im using[b] Oracle Call Interface to execute batch file process. But I have got a problem.
I set ExecuteBatch with the same number of commit time, i.e: 100, 1000 or just 10, for thats ok.
((OraclePreparedStatement)globalStmt).setExecuteBatch(commit);
And I handle executeUpdate to catch all SQL Exceptions. I made some proposital files with invalid erros but when I handle "executeUpdate" it�s doesn�t get the corrent error line, and puts out another line that is corret.
((OraclePreparedStatement)globalStmt).executeUpdate();
Check in the code I concluded that its always get the same sequence of commit number like the error line. For example, I have between line 1 - 50 a line error, this line is 31, but I set the commit time for 50, its show me that line errror is 50 wherever 31. But if I put setExecuteBatch with '1' so it can handle corret lines erros, but the system performance bring down. What is the best way to handle all erros and keep the perfronace?
Sorry for my english, I am not native. Thanks all.

So by doing this, everything will transfer and look exactly the way I have it on the old machine?
That is correct, if your old machine is Intel based after using MA the new machine will look just like the old machine. Here is information from Apple on MA, I'd recommend looking it over.
My recommendation is to answer NO when setting up the new machine when it asks "Are you moving from another Mac?" The reason being let you new machine get set up and run for a couple of hours to ensure it's fine. Then launch MA and follow the prompts, it's very easy and if you use a fast connection like FW it should go smoothly.

Roger

Emac 9.2 freezing and poor performance

Need some new ideas. This computer is an emac Power PC G4 700 Mhz 640 MB (568 unused) running 9.2.2 We mostly use an Omnis 7 program and Internet Explorer 5.1 on DSL. I'm stuck with 9.2 for the program we use. The change in performance was first noticed after an increased internet usage for insurance filing. Sometimes it freezes and requires shut down. Other times it takes minutes for the mouse to respond. We have ethernet in the office and this computer can file share off of two others for some data. None of this is new or changed. The printer is the only other device hooked to this machine. I've read most of the posts on freezing and tried the following on different days but no real fix. Today after restart it takes forever to open a shared file on the network.
- I've run disc first aid from the utilities and Apple Hardware test from the CD that came with it. I've also run everything on Norton Utilities - disc doctor, defragmented, etc.
- I've shut down and unplugged everything over weekend.
- I've run with virtual memory on and off.
- I reset the PRAM
- I've emptied the Server folder. I've had the IE preferences set to store as little as possible. I've been deleting cookies regularly.
- I've checked and reset memory for our program, IE, outlook, etc
- I rebuilt the desktop
I'm not a computer pro, so be gentle. Any help would be great!

Hi, Cherry, and welcome to Apple Discussions. The possibilities that occur to me have to do with a) Internet Explorer, b) your network and c) your hard drive.
Internet Explorer "leaks" memory: no matter how much memory you allocate to it, it will eventually use it all up and take more without asking, if you use it long enough without restarting your Mac. That irresponsible and nonstandard behavior often causes trouble, especially when you haven't given it extra memory to work with. So IE should always be given at least three or four times the Preferred memory that Microsoft disingenuously deems adequate as a default. With IE closed, Get Info on its icon (be sure it isn't an alias icon), click the Memory tab, and increase the Preferred memory figure to 50,000 or 60,000.
If your version of IE isn't 5.1.7, the last one for OS 9, you should update to that version.
You should also restart your Mac at least every couple of days if you make heavy use of IE, and especially if you quit and reopen it and other programs several times a day. Restarting clears and defragments your RAM, which can become very fragmented if programs are opened and quit frequently. Fragmented RAM can also cause freezes.
To eliminate network-related problems as a possible cause of your freezes and stalls, disconnect the eMac from the network for testing purposes. Do the freezes and slowdowns diminish or disappear?
A hard drive that is failing can cause freezes, and often causes drastically reduced performance for a while (sometimes a very short while!) before it stops working altogether. A hard drive that is overly full can produce the same symptoms.
Check on how full your hard drive is by clicking once on its icon and then choosing Get Info from the File menu. What are the figures shown for "Capacity" and "Available"? If the latter is less than about 15% of the former, your drive is too full. That in itself could cause your problems, even if the drive is working fine. But if the drive isn't overly full and disconnecting from the network didn't change anything, suspicion shifts to the hard drive itself.
Since you're working with what is likely to be a fairly sophisticated custom database in Omnis, I hope it's safe to assume that all your data is backed up frequently. If it isn't, now is the time to back it up — don't delay. If your drive is on the way out, it could go over the edge at any minute. Is it making any unusual noises? Did Norton Disk Doctor take an unusually long time to run on it when you did so recently? Does the computer take a long time to start up, or do slowdowns only occur after it's been running for a while?

Crashing and poor performance during playback of a large project.

Hi,
I've been a regular user of iMovie for about 3 years and have edited several 50GB+ projects of DV quality footage without too many major issues with lag or 'dropped frames'. I currently have a 80GB project that resides on a 95% full 320GB Firewire 400 external drive that has been getting very slow to open and near impossible to work with.
Pair the bursting-at-the-seams external drive, with an overburdened 90% full internal drive - the poor performance wasn't to be unexpected. So I bought a 1TB Firewire 400 drive to free up some space on my Mac. My large iTunes library (150GB) was the main culprit and it was quickly moved onto the new drive.
The iMovie project was then moved onto my Mac's movie folder - I figured that the project needs some "room" to work (not that I really understand how Macs use memory) and that having roughly 80GB free with 1.5GB RAM (which is more than used to have) would make everything just that much smoother.
Wrong.
The project opened in roughly the same amount of time - but when I tried to play back the timeline, it plays like rubbish and then after 10-15 secs the Mac goes into 'sleep' mode. The screen goes off, the fans dies down and the 'heartbeat' light goes on. A click of the mouse 'wakes' the Mac only to find that if i try again, I get the same result.
I've probably got so many variables going on here that it's probably hard to suggest what the problem might be but all I could think of was repairing permissions (which I did and none needed it).
Stuck on this. Anyone have any advice?

I understand completely, having worked with a 100 GB project once. I found that getting a movie bloated up to that size was just more difficult with jerky playback.
I do have a couple of suggestions for you.
You may need more than that 80GB free space for this movie. Is there any reason you cannot move it to the 1TB drive? If you have only your iTunes on it, you should have about 800 GB free.
If you still need to have the project on your computer's drive, set your computer to never sleep.
How close to finishing editing are you with this movie? If you are nearly done except for adding audio clips, you can export (share) it as QuickTime Full Quality movie. The resultant quicktime version of your iMovie will be smaller because it will contain only the clips actually used in the movie, not all the saved whole clips that iMovie keeps as its nondestructive editing feature. The quicktime movie will be one continuous clip, incorporating all your edits and added audio. It CAN be further edited, but you cannot change text of titles already there, or change transitions or remove already added audios.
I actually do this with nearly every iMovie. I create my movies by first importing videos, then adding still photos, then editing with titles, effects and transitions. I add audio last, and if it becomes too distorted in playback, I export the movie and then continue adding audio clips.
My 100+ GB movie slimmed down to only 8 GB with this method. (The large size was due to having so many clips. The movie was from VHS footage of my son's little league all-star game, and the video had so many skipped segments that I had to split it into thousands of clips to remove the dropped ones. Very old VHS tape!).
I haven't upgraded to QT 7.5.5, but I heard that the jerky playback issue is mostly resolved with this new upgrade. I am in mid-project with about 5 iMovies, so I will probably plod along with my work-around method, not wanting to upgrade in the middle of any of them.
Hope this is helpful to you.

Skype crashing and poor performance

Hello!
I have a Lumia625 with WP8.1. My problem is that Skype has a really poor performance on my phone. It crashes 6 times out of 10 on startup, and even if I manage to start it, the whole app is slow and laggy. Sometimes I can't even write a message it's so laggy. Video call is absolutely out of the question. It crashes my whole phone. I have no similar problems with other instant messaging apps nor with high-end games. There is something obviously using way more resource in the Skype app than it's supposed to. It's a simple chat program, why would it need so much resource?
The problem seems to be originating from the lower (512 mb) RAM size of my phone model, because I experienced the same effect with poorly written apps, that don't keep in mind that there are 512 RAM devices, not only 1GB+ ones, and use too much resource.
Please don't try to suggest to restart/reset the phone, and reinstall the app. Those are already behind me, and they did NOT help the problem. I'm not searching for temporary workarounds.
Please find a solution for this problem, because it is super annoying, and I can't use Skype, which will eventually result in me leaving Skype.
Solved!
Go to Solution.

When it crashes on startup it goes like:
I tap the skype tile
The black screen with the "Loading....." appears (default WP loading screen). Usually this takes longer than it would normally take on any other app.
For a blink of an eye the Skype gui appears, but it instantly crashes.
If I can successfully start up the app, it just keeps lagging. I sart to write a message to a contact, and sometimes even the letters don't appear as I touch them, but they appear much later altogether. If I tap the send message button the whole gui freezes (seems like it freezes till the contact gets my message). Sometimes the lag get stronger, and sometimes it almost vanishes, but if I keep making inputs when the lag is strong, sometimes it crashes the whole app.
When I first installed the app, everything was fine. But after a while this behavior appeared. I reinstalled the app, and it solved the problem temporarily, but after some time the problem re-appeared. I don't know if it's relevant, but there was a time when I couldn't make myself appear online all the time (when the app was not started). In that time I didn't experience the lags and crashes. Anyways, what I'm sure about is that the lags get worse with time. Idk if it's because of use of the app (caching?), or the updates the phone makes to itself (conflict?).
I will try to reinstall Skype. Probably it will fix it for now. I hope the problem won't appear again.

My solution for: Slow Installs and poor performance

So up until today, most of anyting on XP or even vista 64 ultimate was taking a very long time to install or copy from one part of the drive to another. Startup would grow longer and game performance was dying and only once ever did reinstalling the OS do anything. No matter what I did, nothing would fix the problem.
I ran multiple utilities (disk utility, disk warrior, tech tool deluxe, etc) but none said that there was a hardware problem. But this issue I was having (and I know some of you do) was definitely related to the computer. From my experience, I determined that there was no way this mac was perfect.
So I scheduled a service and repair at my apple store (under warranty). When it was done a few days later, sure enough, I was told that even though the utilities we users can use on our end to diagnose problems didn't find any problems, the hard drive did not pass apple's detailed inspection and was replaced.
In conclusion, I say that if you are having this problem, run disk utility and if you have the extra protection plan, download the Tech Tool Deluxe that apple provides on the support site. Disk utility may find some permission and disk issues but if Tech Tool doesnt find anything even on the surface scan, take it in to the apple store to have a Genius look at it. If it's not under warranty, it's up to you whether or not you want to spend that money. Overall, my computer both on Leopard and XP now runs just as it should.
Hope that helps.

Unable to block unknown, unwanted and offensive me...

I have been receiving a LOT of contact requests and messages from people I don't know. I block them each time and report abuse (as the forums suggest) but I am unable to change my privacy settings in OPTIONS. As suggested by SUPPORT I go into OPTIONS and under PRIVACY I select 'only accept calls, messages etc from my contacts lists' and then I select SAVE, but when I go back in to check, it has reverted to 'Accept calls, messages etc from ANYONE'. The messages I have been receiving from complete strangers are extremely offensive and I would like to know how I can stop them.

not certain of the logic behind this procedure, but it actually work in numerous similar cases. Just switch to offline status for at 5-10 seconds, then revert back to online. Then proceed in changing your privacy settings to desired options and the new settings should stick.
