DHCP - Which OS Actually Send Out Release Messages As Part Of Shutdown Sequence

Mar 2, 2012

I've heard mixed things about the use of DHCP release messages. I've heard that some operating systems don't bother with them at all, which makes sense because many users disconnect the network media without shutting down the workstation. Which operating systems actually send out release messages as part of their shutdown sequence?

Cisco Switching/Routing :: 1841 - Unable To Make Router To Send Syslog Messages To Server

Dec 15, 2012

I am using Solawinds syslog and trying to get our Cisco routers send syslogs to our syslog server. I followed the procedure on Configuring Cisco Devices to Use a Syslog Server from [URL] Our Cisco swtches are all sending syslog messages but not the routers. I compared the config with our access switches but can't seem to find the problem:

Sample router config:
 
service nagleno service padservice tcp-keepalives-inservice tcp-keepalives-outservice timestamps debug datetime msec localtime show-timezoneservice timestamps log datetime msec localtime show-timezoneservice password-encryption!hostname WWF-RT1boot-start-markerboot-end-marker!security authentication failure rate 10 logsecurity passwords min-length 8logging buffered 4096logging rate-limit all 10logging console critical!aaa new-model!!
[Code] .......

is there a command that prevents the router from sending the syslog to the server?

Cisco :: RTP Packets Out Of Sequence

Feb 3, 2013

I've no experience in VoIP and been ditched with looking at an IP trunking problem on our network.The users where getting dead lines or silent calls, but it seems after re-seating IP trunking card here and there around the network a few times, all is settled to normal. Unfortunately it's a third party that look after the majority of the telephony, and as they can't figure out why this happens they often say it must be a problem with the data WAN it traverses.So I started trying to figure something out, I have IPSLA monitoring setup in Solarwinds on most of the routers and all looks well from that aspect; MOS is 4.34 and Jitter is only 1ms at worst. I've taken a wireshark packet capture of the IP trunk by mirroring the port on the switch at a main site where I've been told a lot of calls are routed through. Inside wireshark I used the 'telephony> voip calls' tool and decoded all the calls. The output is showing most calls have 'Out of Seq' and 'Wrong Timestamp' at around 25-50%. Although these calls seem fine otherwise, and I took this capture whilst the fault was not occurring. I know I need to capture next time when the fault is occurring, but this is what I have for now.How can i fix this or even start to troubleshoot further?

p.s- each site has two routers running GLBP to the WAN, over two ISP locations. I read something about having consistent routing to avoid packets arriving out of sequence, but haven't found anything yet to say this is how I can/should do that.

HTTP GET Packet Sequence

May 20, 2011

We have a web server running Joomla.There is a plugin to the website which downloads an iCal file from the internet via a URL. The site gives an error when retrieving this file. I can pull the file down manually via a browser, or doing a wget from the command line. However, the plugin fails. [code]I'm sure there's a packet being dropped in here somewhere, but from which side? Why on earth this would work fine through a browser or wget, but not via the PHP code which executes this GET?

Cisco Wireless :: WLC 7.2.x Release AP Support Matrix?

Feb 28, 2012

I've got a question about the support of AP's in the latest 7.2.x code [URL] We have a couple of AP's that are not referenced in this matrix, does that mean that they are not supported or just that they're forgotten, because we have them running on 7.0.x code.
 
AIR-LAP1120B (nothing mentioned about those)
AIR-LAP1121G (maybe the fall under AIR-LAP1121 ?)
AIR-LAP1230A (only AIR-AP1230A is referenced.. typo ? or are the LWAPped once not supported ?)
 
Whether those mentioned are supported ?

D-link Dir-825 :: Wifi Leds Flash In Sequence

May 17, 2011

For about 3 minutes the 2.4GHz and 5GHz LEDs began to flash in sequence, [2.4-5-2.4-5-2.4-5-Both-Both], it just kept doing that. During that time wireless connections were unresponsive. When they went back to normal I checked the router and it didn't reboot or anything. This is the first anomaly I've ran into running the 2.05NA FW.

On my network I have a Netgear ReadNAS connected and I'm using an add-in (ReadyNAS Remote) that simplifies the log in to for both internet and LAN-users. However, I get a lot of the following entries in the log when that add-in is being used.

When an internet user log in via ReadyNAS Remote: "Blocked outgoing TCP packet from 192.168.0.xxx:3649 to xx.xxx.xxx.xxx:50125 with unexpected acknowledgement 3320366884 (expected 754541166 to 755655246)"

When a LAN-user log in via ReadyNAS Remote: "Blocked incoming TCP packet from 69.xxx.xxx.xx:80 to xx.xx.xx.xxx:50329 with unexpected sequence 3004123085 (expected 3004136875 to 3004393915)"

how to prevent them from occuring?

Cisco AAA/Identity/Nac :: ACS 5.1 Access Rule Selection Sequence

Apr 14, 2011

I just installed a new ACS 5.1 to authenticate wireless PEAP users, so I created an Access policy "WirelessUsers" with identity store being Windows Active directory and all domain users are selected, and create a service rule that dictates that if the authentication protocol is radius, network device belongs to WLC device group, the result service will be "WirelessUsers", so this part worked perfectely, all domain users are able to gain wireless access via their DOMAIN/usernames and domain passwords. Now I want ACS local indentity store users (those local usernames can be the same or different from their AD usernames) to be able to manage those controllers, so I created another access policy "DeviceAdminUsers" with identity store being local users, another service rule which says that if the authentication protocol is radius, network device belongs to WLC device group, the result service will be "DeviceAdminUsers". The problem is that with the setup, whenenve when I try to SSH to WLC, ACS always put me in "WirelessUsers" access policy, even the login name does not have DOMAIN pre-pended or the login name simly does not exist in AD.  if I put the second rule in front of first rule, I am able to authenticate with ACS local username/password and gain access to WLC, but wireless users will fail to authenticate, because ACS is trying to put regular wiress users in "DeviceAdminUsers" access policy. I would expect if username does not exist in AD, ACS should proceed with next rule. Similar requirement was easily achieved in ACS 3.3.

checked lights on router and modem, they all indicated everything was working and normal Reset Modem,Reset Router,Still nothing. Called Comcast, they said everything was working fine from their end.Plugged my laptop into the ethernet connection on router.Plugged laptop directly into modem and it works fine.I saw the link on here to setup the router, and I have 0s on the internet ip, like it suggests at the end.  When I click on the "release" and "renew" buttons nothing changes.

D-Link DCS-930L :: Mjpg Video Stream Or Sequence Of Jpg Images

Sep 14, 2011

When accessing the camera on mydlink, or on a browser using http://x.x.x.x/mjpg.cgi, I would expect the net bit rate to be substantially less than for a sequence of jpg's, since true motion-jpg uses a lossy form of intraframe compression typically yielding a 20:1 data reduction (according to wikipedia). Indeed, I can readily see this reduction in mjpg clips made on my Canon S5is camera. It's not clear whether that is happening with the d-link DCS-930L camera (640x480, quality "high", java).
