[ MacOS ] Jump desktop 闪屏

| No Comments

在运行EL Capitan 的情况下,所有版本的Jump desktop 均出现屏幕闪烁的情况。不十分完美地绕过它只有全屏幕显示这一种办法。谁知道如何修复它呢?

Alarm time Class Description
2013-02-13 19:26:11 UTC Minor Rescue configuration is not set

To get rid of this alarm, simple issue. ' request system configuration rescue save '.

According to this LINK. A vulnerability in the Secure Sockets Layer (SSL) VPN functionality of the Cisco Adaptive Security Appliance (ASA) Software could allow an unauthenticated, remote attacker to cause a reload of the affected system or to remotely execute code.

  1. Login as root.
  2. switchdisable
  3. configremoveall
  4. reboot

To install macOS from a USB disk, you might want to change the system time to finally get it installed.

Example: to install EL Capitan to a macbook pro. You need to change the date from terminal using command:

date 122014102015.30

[ Cisco ] NM-16A / NM-32A

| No Comments

The following documentation from Cisco indicating that you will not be able to use the NM-16A on the Cisco 2800 Series routers.

  1. https://www.cisco.com/c/en/us/support/docs/routers/3600-series-multiservice-platforms/7258-hw-async.html
  2. https://www.cisco.com/c/en/us/td/docs/ios/interface/configuration/guide/ir_nm16as.html

But chances are, you can. I have installed the NM-16A to my Cisco 2821 Router, and it has been recognized and configurable.

Cisco 2821 (revision 53.51) with 419840K/104448K bytes of memory.
Processor board ID FTXXXXXXXXX
2 Gigabit Ethernet interfaces
1 Serial(sync/async) interface
16 terminal lines
1 Virtual Private Network (VPN) Module
DRAM configuration is 64 bits wide with parity enabled.
239K bytes of non-volatile configuration memory.
250880K bytes of ATA CompactFlash (Read/Write)

Just remember, do not plug this module into the upper right slot (marked as EVM only), put it into the left-bottom slot instead.

sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo rm -fr /Library/PreferencesPanes/JavaControlPanel.prefPane
sudo rm -fr ~/Library/Application\ Support/Java

MacOS Capitan 版本在访问ASA 5505 的AIP-SSC-5 时,会出现如下错误。

Unsigned application requesting unrestricted access to system. The following resource is signed with a weak signature algorithm MD5withRSA and is treated as unsigned.

此时,编辑如下文件:

/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/lib/securit/java.security

注释掉如下这行:

jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024

即可启用Java 对MD5 with SHA1 的支持。
