IOS IPS Important Notice - UPDATED

IOS IPS customers running version 12.4T, 15.0M, or 15.1M - a critical software defect has been identified which may cause your router to reload and be stuck in a boot loop if IOS IPS signature version S639 or later is installed on the device. Recovery of impacted devices is possible only via a serial console connection through the device's ROMMON mode. For customers who are using IOS IPS signatures S638 or earlier, there is no issue. Customers wishing to upgrade the IOS IPS signature version to S639 or later must first be running a fixed version of IOS on the device prior to upgrading the IPS signatures. Fixed versions of IOS include: 15.2(4)M, 15.1(3)T4, 15.2(3)T1, 15.1(4)M5, 12.4(24)T8 and later. Please refer to defect CSCtz27137 for additional details and steps to recover impacted devices.
If you have upgraded your version of IOS to 15.2(4)M, 15.1(3)T4, 15.2(3)T1, 15.1(4)M5, 12.4(24)T8 or later you can obtain the most recent signature updates by contacting the Cisco TAC

What is the most recent version of IOS IPS sig file that TAC can supply?
I'm running IOS 15.2(4)M1 and, per your suggestion above to contact TAC for the most recent signature update, I requested a later version of IPS sig than S636.
I was simply referred back to the standard download page and IPS sig file S636.

IOS IPS Automatic Signature Update

I will use cisco1941w.
I'd like to know, how to configure at CLI and where is the URL.
Is the bellow correct?
CLI
Router(config)# ip ips auto-update
Router(config-ips-auto-update)# occur-at 0 0-23 1-31 1-5
Router(config-ips-auto-update)# url https://www.cisco.com/cgi-bin/front.x/ida/locator/locator.pl
Router(config-ips-auto-update)# username XXX password XXX
URL

Hello,
A. Hete is what the six files do:
• ios-ips-sigdef-default.xml: contains all the factory default signature definitions
• ios-ips-sigdef-delta.xml: contains signature definitions that have been changed from the default
• ios-ips-sigdef-typedef.xml: is a file that has all the signature parameter definitions
• ios-ips-sigdef-category.xml: has all the signature category information, such as category ios_ips basic and advanced
• ios-ips-seap-delta.xml: contains changes made to the default SEAP parameters
• ios-ips-seap-typedef.xml: contains all the SEAP parameter definitions
B. So the signature file (.pkg) is decompressed into these files and then 'idconf' loads them in memory.
Hence to copy signature database of one router to the other, we need to copy atleast first 4 files.
You only need to distribute the SEAP configuration if you modified any of the Signature Event Action Override configuration:
We do not have one single file that contains all the signatures. The signature package is installed in a certain way.
Hence we will need atleast first 4 files to copy of signature database from one router to the other.
C. Secondly, I dont know if auto-update will accept a file in .xmz package, I have not tested this.
But I am guessing it will look for a .pkg file and decompress it.
With copying a .xmz file, you may have to manually load it into memory using 'idconf' command.
D. Hence there is no one single configuration file that you copy off the external ftp server.
I guess, the only thing you can do is to have different routers update signatures at different times to reduce load on the network.
It is also not necessary to check for signature updates every hour.
Normal rate of adding new signature releases is every few days, so even if you check around once a day that should be ok.

Is there a way to automate IOS IPS signature updates without CSM?

I have a growing number of 891 routers running IOS IDS/IPS. My Cisco vendor has stated repeatedly that CSM is the only way to manage signature updates to multiple routers, but I'm finding CSM to be incredibly tedious and slow. It also wants to manage a lot more than just the IPS policies and signatures which causes other problems.
I have about 160 routers deployed now and that will grow to at least 600. I have CSM 3.3.1. I'm told 4.x would make it easier becasue it can be configured to ignore more of the non-IPS bits of the router configs, but the upgrade is a big chunk of money that wouldn't be in the budget until at least 2012.
Is anybody doing this with an expect script or EEM applets or something else? It seems to me that I could manually upload an update to one router and push the resulting XML files to all the other routers a lot easier and faster than I could "discover" a bunch of routers in CSM (and rediscover them every time we make a CLI change), add the routers to a group, apply updates to a sig policy, lather, rinse, repeat..., not to mention troubleshooting the weird errors and completely wron "warnings" that CSM spews.
Thanks in advance!

From IOS version 15.1(1)T, you can configure the IOS IPS to auto update from cisco.com which would help I believe.
Here is the configuration guide for your reference:

1841 IOS IPS online updates

Hi,
Can we configure 1841 IOS IPS to get automatic signature updates directly from cisco site. I know we can do it in other firewalls like sonicwall, fortigate, etc.
Regards
Siva K

Hi Siva,
Yes you can do it from the Cisco Security Manager , or you can try
Automatic Signature Update Guidelines
When enabling automatic signature updates, it is recommended that you ensure
the following configuration guidelines have been met:
* The router's clock is set up with the proper relative time.
*The frequency for Cisco IOS IPS to obtain updated signature information has
been defined.
*The URL in which to retrieve the Cisco IOS IPS signature configuration files
has been specified.
*Optionally, the username and password for which to access the files from the
server have been specified.
SUMMARY STEPS
1. enable
2. configure terminal
3. ip ips auto-update
4. occur-at min:hour date day
5. username name password password
6. url url
7. exit
8. show ip ips auto-update

Ever since I had updated my phone to ios 6, i noticed that it no longer saved photos to my camera roll. If i download a picture on on an app, it will not automatically save it to my camera roll as it used to do, nor does it save any image

Ever since I had updated my phone to ios 6, i noticed that it no longer saved photos to my camera roll. If I take a picture on Instagram, it will not automatically save it to my camera roll as it used to do, nor does it save any image, I just want it fixed.

To gdgmacguy your a f****** idiot for one I'm having the same problem as pennymar. And you tell me to quit whinning. You got more problems then the iOS 6 you did not answer my question nor the other 13 or whatever you replied to within a 30 min time frame. You must got nothing better to do then to harass people and to pretend you know something about apple products. Which you don't from what I've read the other advices you should have gave to other people. But you didn't you replied a question back to the people asking a question. So if your not gonna use these community forums the right way don't use them at all.

After I updated to iOS 8, I noticed that while copying photos to my PC, I see photos being categorized into many folders. I also found some system files in each of the folders containing photos (in the name of Local Disk). Is this usual?

I couldn't find the edit button on my original post so I am posting an update here.
I have gone through more apps and have had good luck on all but one more. And it's not that the app doesn't work, I am talking about the Yahoo Weather app, It works fine, but when you swipe between cities the screen lags a bit and it sometimes doesn't move between pages the way it should. On iOS 7.1.2 it was smooth as butter but on iOS 8.0, not so much. I will post a note in the app store to let them know. I really like the Yahoo app better than the new stock app.
I have been going through my games and they all work fine. Angry Birds (Original and Stella), Canabalt, Minecraft, Bejeweled 2, Silly Walks, PopWords, Doodle Jump, Deep Green all seem to work just fine.
Starbucks app works as it should.
I will stop back again next week after I have had the weekend to play with it in detail and post my thoughts again.

HT1222 Has anyone else noticed much greater battery consumption since iOS 5.1.1 update for iPhone?

Since iOS 5.1.1 update has anyone else noticed a much greater battery consumption on all fronts? My phone used to rock steady all day and know is around 47% 12 noon to 1 pm with the same amount of usage.

Heres a support question... how the **** do I fix the dramatic battery drain problem that came about after installing 5.1.1? Suggestions for fixing problems on iTunes did not work.

Correct procedure to update IOS IPS signatures on 2911 router

What is the correct procedure to update the IOS IPS signatures on an 2911 router?
I know how to download the signatures file (eg. IOS-S556-CLI.pkg) but what is the correct way to install the update?
Thank you in advance!

The IPS signature package comes with a list of pre-enabled signatures, hence Cisco does not recommend enabling a lot more other signatures, especially not every single signature as documented.
The reason why is because the package might include retired/old signatures only for references, and not every single signature is required to protect your environment because you might not have the traffic for some signatures, you might not have some end hosts that are written with specific signatures, therefore, it becomes irrelevant if you enable it.
Typically here is how customer would enable/disable signatures:
- Use the default signature that is enabled by Cisco (the default should fit majority of the customers).
- Monitor it for a couple of months
- Disable those that you don't need, and enable others if you think you require it for specific.

IOS IPS auto-update

Hi,
I have a couple of questions I hope people could answer:
1) What recommendations/options are available for downloading signature files to a HTTP/TFTP server prior to having the IOS IPS device pull them from the server? Is their a way to automate the HTTP/TFTP server downloading the signatures? (Cron job or such)
2) Does the signature file name change each time a new signature file is released? If it does, would I have to go back to the router to update the URL string that is configured in the ip ips auto-update section? I would hate to have to update 200 CPE devices each time a new signature file is released.
Hoping someone could answer these or help point me in the right direction to find the answer out.

IOS IPS Sig Updates

It seems like whenever there is an IDS sensor/appliance update for defending against the latest virus/worm but there is no update for IOS IPS signatures.
Case in point - on June 3 there was an IDS update for W32/Bobax.worm.o S174. The IOS IPS zip file as of today is S169 from May 25, What gives?
Also, why isn't their any release notes for the IOS IPS zip files to document what was added? That way we can read it to judge if we need to download the zip file or not.

There are a couple of extra steps in producing the IOS IPS signature update. The IOS IPS solution is a subset of the full appliance solution and is further constrained by memory limitations inherent in the routers that it runs in. Because of this, once the signature development team puts together an appliance update, that update has to be reviewed to make sure that the appliance signatures won't crash the IOS implementation. Any issues found during the review have to be addressed before the IOS update can be posted. This extra review step is the cause for the delay.
Regarding the release notes. The signatures usable by the IOS solution are a subset of the appliance update. You can look at the appliance update release notes to see what *might* be available. I say might because of the subset issues....

IOS IPS SIG Updates via IDSMDC

When using IDSMSC to push out updates for Sensors and IOS IPS devices, the signature update process pushes the updates to the sensors during the udate process. However the IOS IPS devices pulls their signature definitions from the server itself.
So my question is, do you need to "Generate" and "Deploy" to all IOS IPS devices to insure the devices are updated with the latest signature definitions after the update?

IOS IPS Signature Updates

Hi,
Is it possible to update signatures for IOS IPS or do we need to update the IOS to get more signatures?
Thanks and rgds
Rajesh

hi,
if you have cisco sdm, then it would be easy to update your IOS IPS signatures. You may need to upgrade IOS of the router only when the ips signature requires you to do it.

IOS IPS auto-update without CSM

Hi,
We have 400 x 1811 router on which we need to update the IPS signature definition and custom signature.
What is the best way to do it withou running CSM ?
According to Cisco documentation, we need to add the auto-update command with an .XML extention. But when we load a .pkg in a router, the output is 4 different files. Unfortunalty we can auto-update only one file. Which one to I need to load on our TFTP server ?
All the exemples of Cisco are using one single XML file.
Does a single file with the signature defenition, category, default and type exist ?
Since all our router have the same IPS config, I tought I could use one router at the central office with the configuration we want. And by someway asking the remote routers to auto-update their XML file on that router on which I would have activated a TFTP server.
Anyone ever had to upgrade a lot of router IOS IPS signature?

This can now be done in the 15.1T branch using cisco.com to download the update directly, see :

Problems with sound from external speakers after iOS 5.0.1 update

Have others experienced problems with external speakers on the Iphone 4 after iOS 5.0.1 update? My phone no longer rings, sounds when i receive a text message, sounds alarm, etc. Vibrate works fine and when i plug in headphones I can hear music through the headphones. Any fixes for this?

Hi Guys,
I have post eariler on another forum and I have the same problem, I have tried all the things listed here and nothing was perminant in fixing this painful iphone hating problem.... and failed. You probably have the problem when you use youtube or your music external speaker that there is no volume bar and no sound.   I have had the same problem But I need to happily say that I now have the fix!!!! This worked for me and I fixed it by myself so you don't need to go to apple or service centre or anything.
Ok I like so many of you here truly believed this was as IO5 issue as it only dropped the sound on the speakers once that IO5 update came along. I tried a bunch of reset, reboots, home clicks, lock and unlocks, to fix this and all failed. some worked for an hour but then failed. hours of my life that I will never get back.   but since I have learnt this is not a IO5 problem but a hardware issue! ... and in paticualar is has to do with your bottom connection. Your phone is thinking it is docked all the time.
To fix the no sound problem what you need is...
1. a torch
2. a tooth brush
3. methalated spirits
4. a butter knife
Step 1.
get your torch and shine it down the bottom connection plate to see what kind of dust, sand, hair or anything you have stuck in there.   all that need to be removed! everything! it might look clean but still thats ok go to step 2.
step 2.
Turn on your music app and put the speakers on! If your phone is like mine it should not work. you most probably don't even have the volume display to turn it on but its ok, just do it! and it should still play with no sound.   its important you try and run the speakers as this will show you that it is a hardware problem.
step 3.
Dip your tooth brush into some methated sprits.   then at your sink tap the exess metho out of your brush as you just want the brushes to be slightly damp, not soaking wet and then scrub the bottom connetiors on your iphone. work the brush back and forward in a way that scoops the dirt out of the phone, not just pushing it side to side.
(As you bushing you should notice the volume bar come back on or off as you scub.   This happened to me and that is how I realised I was on the right track to fixing this problem as I was doing something external that was actually controling when the volume display came on or off.   but once I cleaned it this still didn't fix the problem...)
Step 4.
Use the back side of a butter knife (not the sharp side) to gently slide over the connectors on the iphone. Do this gently as you are only pushing down on the tiny metal contect bars and you should notice the volume display come on again. slide it back and forward. Now the area of interest is about 2/3 along the connection plate to the right.   This is the area that has the infomation sent when your iphone thinks its docked.
This has worked for me and I have not had a problem since I did this 2 weeks ago.   I have since learnt that the new IOS 5 has activated a different part of the bottom conectors. if you have been using dodgy connectors or unapproved apple cables (as I was) any damage or hair and dirt on the terminal this is effecting it. Try it.   just remember if you can do something external to your phone then there lies the problem.
Hope this works for your phone as it did for mine.
Cheers
