Feb 8, 2012My problem lies with my router shutting off when my computer goes to sleep or is shut off in any way. I even tried unplugging it, which is not good at all for it.

View 1 Replies View RelatedCisco Routers :: RV042 TLS Security Scan Failure
Mar 30, 2013As part of my business' PCI compliance regime, we are regularly scanned for vulnerabilities. Today we started getting notifications of failure on all of the QuickVPN ports (443, 60443) for the following:
Details: Multiple Vendor TLS Protocol Session Renegotiation Security Vulnerability
06/11/12 CVE 2009-3555 Multiple vendors TLS protocol implementations are prone to a security vulnerability related to the session-renegotiation process which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context.
Cisco, will you be issuing a firmware update to address this anytime in the near future? Presumably it effects all the other RV routers as well.
Cisco Security :: 3750 Core Crashes During Nessus Scan
May 24, 2011I'm currently investigating an issue for one of our customers where one of their 3750 Core Switch Stacks crash / becomes unresponsive during a NESSUS Scan.
They've diabled DoS testing and have ensured that safe scanning is enabled. For the test they are port scanning all of their VLANs (around 600 internal addresses).
The network consists of 2x 3750 Switch Stacks connected via fiber, edge switches connect into these cores. Both cores are running HSRP, for VLAN gateway redundancy.
Issue Being faced is as follows:
During the scan, Core 1 becomes unreachable from Core 2. We can telnet to Core 2 and administer as necessary. However we cannot telnet to Core1, a console connection also fails - the switch stack is unresponsive, but does respond to pings.
On Core 2 I've performed a show proc cpu sorted and can see the IP Input process is running at around 60% and the CPU is highly utilised.
Once Core 1 becomes unreachable the network gradually grinds to a halt, almost mimicking some sort of broadcast storm or Spanning Tree loop.
Interestingly Core 1 HSRP is still active, so the hello packets are still being sent.
The only resolution to the issue is to perform a hard reset of the Core to restore service.
Logs from core 1 show the CPU becomes fully utilised. There is also an error logged indiciating:
%FIB-2-FIBDOWN: CEF has been disabled due to a low memory condition. It can be re-enabled by configuring "ip cef [distributed]"
Both cores are running IOS 12.2.(52) SE IPBASE. I've attempted to reproduce the issue in the office here and although a NESSUS scan does increase switch CPU utilisation I couldn't reproduce the failure scenario.
What may be causing the 1st core to become unresponsive? I've found some articles with regard to a 6500 switch rebooting during a NESSUS scan, and also some HP switches exhibiting similar behaviour but nothing that matches the exact scenario I'm investigating.

Aug 13, 2012I'm trying to enable port security on several 4507R's. When I try to configure a range of ports the switch will randomly put 1 or 2 in err-disable. It's different every time I apply the config to the same group of ports. However if I do them one at a time it seems to work. But I really don't want to configure 6 fully populated switches one port at a time. We also have a lot of 3750's and they gave me no problem using a port range. [code]

Jan 1, 2013I have set up access restriction times for my son (we have wireless access for all systems). I use the MAC address on his systems. Xbox, Kindle Fire and his Laptop. The MAC address are Correct. Here is the problem:
I set the "allow" and times from 6pm - 11:00 pm (while on xmas vacation) - the system works for a while he is shut off as i would like but....
After a period of time the entire house goes off line. I have to reboot the power on e2000 router and then disable the access restrictions. System then works. Problem is repeatable. What is the deal. I have updated firmware already. Otherwise the system works great. Never dies. Just when i set access restricions for a SPECIFIC time it kills entiore houese. BTW i can deny him outright 24/7 and the system idsables his access fine. Its just when i set specific times

Anyway, I came on here because our computers use a Wi-Fi internet connection and I was wondering how much of my web activity (history, cookies, temporary files, etc) he could see from my laptop if his computer was a desktop downstairs. He's very tech-savvy (a former IT guy) and I don't want him snooping through my personal records.
