Cisco has pulled the release notes for WLC version 6.0.199.0

http://www.cisco.com/en/US/products/ps6366/prod_release_notes_list.html

Coincidence? Could this be due to the Vocera bug or just an oversight by a webmaster? The code is still available for download and it’s still listed on the AssureWave site (hah!) – just no release notes…

SQL Injection Vulnerability in Cisco WCS

Cisco Wireless Control System (WCS) contains a SQL injection vulnerability that could allow an authenticated attacker full access to the vulnerable device, including modification of system configuration; create, modify and delete users; or modify the configuration of wireless devices managed by WCS.

This has been fixed in version 6.0.196.0.

Making the Cisco IOS DHCP server useful

Yay for learning! Two of the features that I was under the impression were missing from an IOS based DHCP server are infact present:


1) The ability to ping clients prior to handing out an address:
Router(config)# ip dhcp ping packets 5
Specifies the number of ping packets the DHCP server sends to a pool address before assigning the address to a requesting client.

Router(config)# ip dhcp ping timeout 850
Specifies the amount of time the DHCP server waits for a ping reply from an address pool.



2) The ability to retain a DHCP leases table across reboots:
Router(config)#ip dhcp database flash:router-dhcp write-delay 60 timeout 10
Configure DHCP database location on a physical storage medium, this prevents the router from loosing all of it’s lease data after a reboot. By default, the router maintains the dhcp bindings in NVRAM.

WARNING: Vocera + Cisco Assurewave 6.0.199.0

Those of you that were getting ready to roll up into WLC release 6.0.199.0 soon may want to reconsider if you’re on a Vocera deployment. I don’t know anything more significant than the below warning from Vocera and am trying to get additional details. If you know of anything specific, please speak up! 🙂

What this is all about

So, a well-respected colleague of mine suggested that I create a place to put my various tidbits regarding wireless networking since I have a tendency to share them with my co-workers and various other small selected groups. This is that place. I plan to start sending thoughts and comments about the wireless world here as a place I can go to reference past suggestions and links. Primarily this will be regarding Cisco wireless products but occasionally I have something useful to say about RF in general and other related topics. If you find anything I say useful, let me know!
