Ping on ios

Hello everyone, I discovered that when I do a ping on my router (192.168.1.1) local, Ping is about 30 ms, which is very high, but when I'm with airplay, the same test give me a ping of 2 ms, which is normal. you have the same problem?

ON the picture you can see ping before and after the air game is activated

Thanks for your replies.

I suspect the iPads wifi radio is in low power mode when no data is sent. This can have an overhead projector as the effects of the weather. iOS is not a 'performance raw BONES' is designed to save energy when it is possible to improve the user experience.

When you run radio Airplay is sending and receiving data constantly, so the ping is faster that the radio is not disabled and re-enabled. The schedule isn't too out of the ordinary for me, you have a problem or you're simply curious?

Try again when the download / streaming video or something that keeps the wifi connection active, it cannot be just Airplay making faster ping.

You should also know that the router is another part of this conversation - it allocates resources to the stream to devices too, it may be faster when not having does not respond intermittently to a device. It also directs clean power for radio, etc.

How to get the time limit requested when ping external interface FW IOS?

After I install CBAC on an IOS Firewall Router and deny all incoming ICMP request, I ping the external interface of the router and I get "response from the (the external interface IP): the unreachable destination network. I think it's quite risky because my IP from the router's external interface is known. How can I set up such that I can get "Timeout asked" instead?

Hello

Try not to implement the "unreachable no ip" of your external interface.

This command prevents the router ICMP unreachable sending at all.

I installed vpn client on windows 2000 with local authentication of IOS. First problem is that the sending of subnet mask of IOS is not correct, I use the class A address with subnet mask of 24-bit. I change this configuration in network connections (windows 2000) no longer reach interface internal ping to the router.

My email on my iPad (version 8.4.1) application froze on a white page. I tried to power down and restart. I know I get emails that I can hear the ping and see numbers on the app. It has been frozen for a day and I have no way to display

My email on my iPad 2 (IOS 8.4.1) froze last night on a blank page I was trying to send a few photos. I know I get emails that I can hear the ping and my email application shows that I have two new. I tried to put this off, then restart, but nothing changes. When I type my email application it goes to the blank page and after a few seconds goes back to my home page. I'm leaving on a trip to Europe at the moment I'm in a bit of panic. Any help will be greatly appreciated.

Slow Safari and Firefox ping

Hi all

I use Safari 9.1 than my normal browser and OS X on a MacBook Pro late 2013 10.11.4.

I tested my internet speed (speedtest.net) on all devices and noticed that my 6s iPhone and iPad 2 air both iOS 9.3.1 (speedtest.net app) had a ping of less than a third of that of the MacBook Pro.

Then I tried Google Chrome 49.0.2623.112 (64-bit) and the speed is as fast as with iOS devices. Then I went 45.0.2 Firefox and it was as slow as Safari again.

For the last test, I disabled all extensions in Safari, but has not made a difference.

Is there a setting to speed up Safari on OS X, his counterparts of iOS? I would rather not use Chrome on battery because I lose an hour of battery time.

Thank you all for your help.

Safari/Preferences/Advanced - activate the menu to develop it, then go ahead and empty Caches. Quit/relaunch Safari and test. Then try Safari/history/Show History and remove all items from the history. Quit/relaunch Safari and test. You can also try try Safari/Clear History... The downside is that it deletes all cookies. It could upset some sites no longer recognizes your computer as one that has visited the web site. Go to Finder and select your user folder. With this Finder window as the windshield, select Finder/display/display options for presenting or order - J. When the display options opens, check "show the library folder. This should make your visible user library folder in your user folder. Select Library./Caches/com.apple.Safari/Cache.db, and then move it to the trash.

Go to Safari preferences/Extensions and disable all extensions. Test. If correct, enable the extensions one by one until find you which extension is causing the problem.

Q: who will degrade the original quality of scan inside the pdf at all?

No, not at all.

-BTW: I saved a pdf scan that the ping (150px) test and it was bigger than pdf - perhaps silly if for re - record - just keep as a pdf?

Yes. PDF is fairly compact, as it is.

PDF is a more universally acceptable PNG format. If you are willing to sacrifice the details, you can export it to JPEG.

complete network slow after upgrade to iOS 9.2

Hello

obviuosly the update to iOS 9.2 decreases my network speed for all devices on the network. I tested the speed with public speed tests and answers have been slower than before the update (e.g. ping time before: 42ms; after: 1500 ms; even with downloads and uploads). If I turn off my iOS device, it is faster still.

Someone has the same effect? Or does anyone have advice what to do?

Thanks for help

TcL (Ping/Trace) validation script

I'm looking for a script that I can use to help simplify the validation steps of my when I do work on my devices. I usually have anywhere from 2-10 IP addresses I need to validate (generally less than 5 although). My common steps are to ping to each of my IP addresses and I have run a traceroute to these IP to validate that they are initially accessible second then I need to validate the path that is taken is correct before my work and then after my work. So far, I'm here its a TcL script that I could use to Ping, but not trace. Ideally it would be nice if I could run single command line for each IP address and then when I press on enter the script will do the rest.

a sample of what I want to do is to type:

Name of the script: validate

R1 (tcl) #validate x.x.x.x y.y.y.y z.z.z.z

The Ping script, I found is underneath. I like it because it is not dynamic enough to what I was looking for, and I can't seem to make this work for the trace.

R1 #tclsh

R1 (tcl) #foreach address}

+ > (tcl) #172.12.23.2

Thank you

I'm also learning TCL and I can help some of this for you.

The reason why you get an invalid argument is that you use argv that only accepts the arguments when you call a tcl script to run from a command line and you add arguments to the end to feed in the script dynamically.

for example if you record a script called pingtest.tcl in the routers flash, then after the .tcl are your arguments that argv will soak in

in otherwors ' command line arguments are stored in the named list ' argv '.

Pingtest.Tcl 192.168.1.1 192.168.1.2 192.168.1.3 etc etc.

I would recommend for now just turning it into a procedure that you can use in the shell interactive tcl on the router. After you do that then you can you forking by saving in flash or whatever.

To turn it into a procedure, you can forget the argv stuff and just put the ip address directly in the proc argument.

This means that when you call your proc name it will execute the body of the procedure using the argument in the proc.

have a go at this. To make it cleaner, you can create a variable placeholder for all peoples to validate.

What this will do, if the ping is successful, then it goes on to run the traceroute.

However if the ping command then no traceroute is run and it will be the next IP in the list.

EG-

the value of intellectual property "192.168.1.1 192.168.1.2 192.168.1.3 192.168.1.4 192.168.11.5 192.168.12.5 192.168.1.5 192.168.1.6 184.32.33.1 192.168.1.7 192.168.1.8 192.168.1.9 192.168.1.10.

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

END

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

-its worth worth noting the traceroute of tcl command is also finiky, if you use exec he is most likely don't work and just hang until all 30 jumps are doing. (potentially ios version to load that I read a few posts Josephs on similar problems with it)

It would be easy to convert argv. Simply replace foreach IPAddress $argv and get rid of the procedure.

Traffic generated by router IOS inspect IPv6

I try to configure the IPv6 packets on a router 2911 deep inspection (IOS 15.1 (2) T5) but I'm not able to inspect the traffic generated by router. It is not an option "ipv6 inspect name xxxx udp router-traffic' as in IPv4. So I am unable to ping to the router to a remote host.

I could solve the problem of ping by simply adding a "permit any any icmp echo response" on my ACL, but I still can't access TCP or UDP based services (DNS, HTTP,...).

Anyone knows if it is possible to activate the traffic generated by IPv6 router, or is there another solution for this problem? If so, how can I do that?

Partial configuration:
```
ipv6 unicast-routing

ipv6 inspect name SPI_DIALER1_OUT tcpipv6 inspect name SPI_DIALER1_OUT udpipv6 inspect name SPI_DIALER1_OUT icmpipv6 inspect name SPI_DIALER1_OUT ftp
```
```
interface Dialer1 ipv6 inspect SPI_DIALER1_OUT out ipv6 traffic-filter acl6_dialer1_in in
```
```
ipv6 access-list acl6_dialer1_in sequence 10 permit icmp any any nd-ns sequence 20 permit icmp any any nd-na sequence 30 permit icmp any any router-advertisement sequence 40 permit icmp any any echo-reply deny ipv6 any any log
```
Former Cisco's IOS 'inspect' system has indeed been deprecated. You should use zone based firewall now.

Here is the guide for the care of the IPv6 zone based firewall.

If you want to go at a faster speed for the area based ipv4 firewall, try to use my Config Wizard and copy the bits you need.

ASR9K | drop packets when ping provider of next hop.

Hello guys,.

I have an ASR9k and one of its interface connected to BT supplier multiple subinterface and corresponding VRF is configured on this 10G link.

The question is: when I ping the next hop (BT ip address) with meter 1000 and the 1500 mtu size, I get a success to drop and 98% patterns. This decline of 2% packet affects traffic voice on it.

My MTU configured as 8900 and mtu configured as 9058 BT and as it is not more traffic so I don't think that the configured Qos policy is applied on the movement.

UserEnd to ping server is fine but still I'm down 2% on a point to clicking on supplier link, can you please give some idea about this to solve?

Hello

I think that what is expected. Since it is a drop of water to grounds, this indicates that there is traffic is limited in rate or some sort of CoPP in game.

In IOS XR, LPT plays this role. Maybe it's rate limiting of traffic from the ping packets are destined to the CPU.

Please refer to the below document Xander:

https://supportforums.Cisco.com/document/93456/asr9000xr-local-packet-tr...

Hope that clarifies

Defining a 1852nd Aironet AP - Radio Off - Cisco IOS 12.3 (4) JA

I have a brand new Cisco Aironet 1800 AP series I'm trying to install. Specifically the 1852E. I do not have a controller and try to use the method of deployment of mobility Express. When I received the unit there is a yellow label more precisely declaring outside: "OFF BY DEFAULT note RADIOS: radios are disabled by default for Cisco IOS releases 12.3 (4) JA and later.

If anyone can please tell me how I am supposed to this access point configuration when the radios are not suite, so the CiscoAirProvision SSID is not broadcast?

I tried the following:

1 connect the unit to my PoE switch. Unit Gets power and discovery mode starts (red/orange/green light cycling). He succeeded receives an IP address from my DHCP.

2. when I try to access the device through my laptop via the local LAN it just times out. Pings meet.

I apologize if my post seems harsh, I am quite agitated that even after having spent more than 5 hours trying to troubleshoot and get this thing to work, there was nothing else than a nightmare (both for the installation of touted 10 min). I do RTFM. I missed something simple jumps? or am I just to assume that Cisco has really missed the boat the patch appropriate for an assignment in their literature.

FOR INFO. Thorough searches Google and research on this forum gave me no help.

Thank you.

Any ideas?

Thank you.

I see ip nat inside and ip nat outside interfaces configured on. But I don't see any translation of address configured. This would preclude anything inside the unit to be able to access the Internet.

The ping of death Protection options

Hello

I want to secure my network against ping of death attack. The IOS IDS allow the detection of this type of traffic, but it drops the ICMP packet? If I have any FW IOS, what are my options to protect my router, is this ACL enough:

access-list 101 deny icmp any any fragment

Thanks for your help and your comments!

François

Hello Francois,.

You asked "could someone confirm me that the IOS IDS is also able to prevent these reach by Ping ICMP 'abandonment' of the death packages? Response will be displayed. By configuration Cisco IOS Firewall Intrusion Detection System

http://www.Cisco.com/univercd/CC/TD/doc/product/software/ios122/122cgcr/fsecur_c/ftrafwl/scfids.htm

2154 Ping of death attack, Atomic

Triggers when an IP datagram is received with the Protocol field in the header set to 1 (ICMP), IP the last Fragment is defined, and

(Offset IP * 8) + (length of IP data) > 65535

In other words, the offset of the intellectual property (which represents the starting position of this fragment in the original packet, and which is in units of 8 bytes) and the rest of the package exceeds the maximum size of an IP packet.

Hope that helps! If Yes, please rate.

Thank you

IPSec between an IOS device and a PIX

Hello

I'm not able to successfully establish an IPSec tunnel between an IOS (2600 router) box running 12.3 (9) and PIX501 pixos 6.2 running. I see the following error on 2600.

* 06:09:50.416 Mar 10: ISAKMP (0:1): will increment the error counter on his: broadcast

And on PIX501 following error message:

Hello Krishna

If possible and feasible to try and downgrade the IOS 12.3 (9) to a low-level code as 12.3.6. But, make sure that the image is a single k9 and supports VPN. Also upgrade the pix to 6.3.3.

Assuming that the keys are the same, your configs find ok. Him debugs it seems its not able to pass from the phase 1 properly

could contribute to modify the code.
