Can I get alerted if my router is hit with a DoS or Scan?
Hi,
I have a Cisco 877. I have IPS installed and mondered how or if I could be alerted when it's constantly scanned by an external IP?
I have seen my syslog server fill up with deny's from external IP's and wondered if I can be notified, or is it regarded as the router is doing it's job so don't worry?
Thanks in advance for your info
Hi,
Not sure if this works on an 877 (I don't have one) but this might be a good start:-

You'll need to change the syslog pattern to something more appropriate.

E65 can't get through my wlan router
My Nokia E65 can't get through my wlan router. Can anybody help?
When using wireless at home I can browse the wifi-router homepage (192.168.0.1), but the Internet application won't load internet pages.
I've tried different security settings, even totally open. Always the same at my TrendNet TEW611 BRP using default settings. At other routers internet is ok.
What's strange is that the SIP phone application gets through, so I can make phonecalls but no internet. Can anyone explain this?try to connect using WiFi connection manager like HandyWi, www.handywi.com, if that still doesn't work when it's probably something wrong with the settings on your router. Can also be that the page your are trying to load is too large for the mobile browser to process.

Hi Team ,
As part of Disater Recovery Test ,Higher management team is going to delete One Database from one of my production SQLServers .We need to find deleted database and need to restore the Database from Backup files ?
Q)How can find we deleted database information through alerts, notifications and scripts ?i.e can we get alerts or notifications if Databse is deleted ?Pls share scripts or technical steps?
Q)If we delete a database , will that information be recorded into SQLserevr logs , Windows application logs ?If yes ,pls share the Event ID fot that deleted database ?
Thnaks,
Venkat
Venkat ThotaThere is one way:
SELECT Operation, [Transaction ID], [Begin Time], [Transaction Name], [Transaction SID]
FROM fn_dblog(NULL, NULL)
Here pich the [Transaction Name] and [Transaction SID]
Now below query will provide user name
USE MASTER
GO
SELECT SUSER_SNAME(Transaction SID)

If you mean hiding or unhiding apps, the article is incorrect since iOS 6 and the accompanying iTunes Store redesign were released. You can at this time only hide and unhide apps through iTunes on your computere.

I can't get my HP laserjet p1102w to work with airprint
Hi!
So it seem's that I can't get my HP laserjet p1102w to work with airprint. I got it to send out it's own Wi-Fi signal, and i get in touch with that signal on my iPad 3. But when I wan't to print something out from Pages, then it says that it can't find any airprinters.
I tried to update the firmware several times, but it still doesn't work. Any suggestions to what I can do?Hey T-racer,
As a work-around you can also use the HP eprint method which is available with your printer. The application (HP Home & Biz) is available for free in the apple catalogue.
You can find more info on it here:
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03128518&cc=us&dlc=en&lc=en &product=4110396&tmp_track_link=ot_search
It shares many of the same capabilities of airprint but is a different program/feature.
If you have any questions, just ask!

How can I get a copy of my iphone messages with the number it was sent from and the date and time stamp? Needed for court purposes.
Try the computer apps PhoneView (Mac) or TouchCopy (Mac & PC):

You should probably consult your attorney to see if either of these will be acceptable. -

Can I get OCR software for a 8600 plus with a mac??
can I get OCR software for a 8600 plus with a mac??
if so , how?
This question was solved.
View Solution.Hi,
An OCR software i integrated within the HP Scan Software.
Within the Applications folder locate the Hewlett-Packard folder and launch the HP Scan software.
Once completing the scan you may select RTF or TXT files which will save the scan by processing OCR.
If you do not have the HP Scan software installed be sure to install the following software by checking the HP Scan option during the installation:
