My Cisco IOU Racks - from flyxj IOUv3

My Cisco IOU Racks:
- from flyxj

Vmware configuration:

I have modified Interface IP to match my local configuration:

Root password is flyxj.cn

Change IOUv3 interface ip command:

root@flyxj:~/LAB# ifconfig eth0 192.168.80.160

This is topology looks like. Totally there are six routers and four switches. Good enough to finish most routing / switching lab.

Enabled R1 and R2. Now it shows green in the topology.

File Copy Between Two Juniper SRX Cluster Members

I have two SRX Cluster Members and managed from remotely. Each time when transferring package file remotely it will take several hours for 140M new junos file.

File copy command can copy file between routing engines but looks does not work well on SRX Cluster.

I tried to login into routing engine re0 or re1 on SRX. It is always in same routing engine. But with node 0 and node 1, it works well.


root@fw-1% cli
{primary:node0}
root@fw-1> 



root@fw-1% request routing-engine login re0  
root@fw-1%

root@fw-1% request routing-engine login re1
root@fw-1%


root@fw-1> request routing-engine login node 1

root@fw-2> file copy /var/tmp/junos10.3.tgz re1:/var/tmp/junos10.3.tgz
re1: No route to host
re1: No route to host
error: put-file failed
error: could not send local copy of file

root@fw-2> file copy /var/tmp/junos10.3.tgz node0:/var/tmp/junos10.3.tgz
ssh: Could not resolve hostname node0: hostname nor servname provided, or not known
lost connection
error: put-file failed
error: could not send local copy of file

After a couple of times try, I found a way to use fxp0.0 interface ip to do file transferring:
  file copy /var/tmp/junos10.3.tgz 10.2.8.4:/var/tmp/junos10.3.tgz

and the speed is 2.2MB/s. pretty nice. And file transferring can be done in 1 minutes.

Juniper NSM Schema Upgrade Failed

My Juniper NSM version is 2012.1R6.
Tried to upgrade Juniper NSM Schema online from current 280 to latest 293, but got following failed message:

Error Code: 

Error Text:
   Schema Download Failed.

Error Details:
   No such file or directory
svn: Can't open file '/usr/netscreen/GuiSvr/var/dmi-schema-stage/nsm/dmi/junos-es/releases/12.1R5.5/.svn/text-base/config.xsd.svn-base': No such file or directory

Basically this NSM will have to manually upgrade schema, online is not working. Here are steps for how to do it:

1. Juniper KB13555 - [NSM] How to revert dmi-schema to the original installed version

2. Juniper KB12756 - [NSM NSMXpress] NSM Offline DMI schema update

Note: Technote ID:TN86 -NSM & Junos Compatibility Matrix, will be needed to download latest Schema from Schema Offline Download Links.

Excel Formula : Convert a text to Number

Got a Excel file from other resource witch Column A is set as text. At the tail and start of number there are some spaces filled in, for example cell A1 is '  4 '.

My challenge is to convert whole column to numbers which can be used to do sum or other math calculation.

With some research, I constructed this formula for a new column :
=VALUE(TRIM(CLEAN(SUBSTITUTE(A1,CHAR(160)," "))))

it perfectly resolved this challenge as you can see from following screen shot.

Note: trim will not work with the only space cell. Thanks reply from Hari Krishna.

Checkpoint SmartDashboard Error - No Rule Bases Exist for the Policy Package

Got this issue in the morning. Searched the Checkpoint Support Site and found sk72440

CAUSE

$FWDIR/conf/applications.C* and $FWDIR/conf/CPMILinks* files have become corrupted on Management Server / Multi-Domain CMA.

SOLUTION

To resolve this issue, remove the $FWDIR/conf/applications.C* and $FWDIR/conf/CPMILinksMgr.* files from the Management Server.

On Management Server: 

1. Stop Check Point services:
   
   [Expert@HostName]# cpstop
2. Go to $FWDIR/conf/ directory and remove applications.C* and CPMILinks* files:
   
   [Expert@HostName]# cd $FWDIR/conf/
[Expert@HostName]# mkdir backup_cache
[Expert@HostName]# mv $FWDIR/conf/applications.C* $FWDIR/conf/backup_cache/
[Expert@HostName]# mv $FWDIR/conf/CPMILinks* $FWDIR/conf/backup_cache/
3. Start Check Point services:
   
   [Expert@HostName]# cpstart
4. Connect with SmartDashboard to Management Server.

Notes:

• $FWDIR/conf/applications.C and $FWDIR/conf/CPMILinksMgr.db will be created again automatically.
• The '$FWDIR/conf/backup_cache' directory can be removed after the solution is verified.
