[solved] ERROR: Unable to set this url, file has non-ASCII characters

The following error message is occurred because the command is not put in the right order.

ERROR: Unable to set this url, file has non-ASCII characters
or
WARNING: BOOT variable added, but unable to find disk0:/.private/startup-config

ciscoasa#
ciscoasa# con t
ciscoasa(config)# boot config disk0:/.private/startup-config
ERROR: Unable to set this url, file has non-ASCII characters
ciscoasa(config)#

SOLUTION

The right sequences are as follows:

enable
config t
copy run disk0:/.private/startup-config
boot config disk0:/.private/startup-config
wr mem

EXAMPLE

ciscoasa(config)# copy run disk0:/.private/startup-config
Source filename [running-config]?
Destination filename [/.private/startup-config]?

How to “wr mem” Cisco ASA in GNS3?

On a previous post, I’ve shared how to save Cisco ASA configuration in GNS3 environment. If you don’t like this way, there is a good news for you. wr mem command still can be used, but you need to execute the following command.

copy run disk0:/.private/startup-config
boot config disk0:/.private/startup-config

After that, wr mem command is good to go

EXAMPLE

ciscoasa(config)# copy run disk0:/.private/startup-config
Source filename [running-config]?
Destination filename [/.private/startup-config]?

%Warning:There is a file already existing with this name

open(ffsdev/2/write/40) failed

ciscoasa(config)# boot config disk0:/.private/startup-config
ciscoasa(config)#

ciscoasa(config)# wr mem

[solved] How to save configuration Cisco ASA in GNS3?

If you use Cisco ASA in GNS3, you’ll be notice that “wr mem” command can’t be used to save a configuration.
The following error message occurs once you run “wr mem”.

ciscoasa# wr mem

%Error opening disk0:/.private/startup-config (No such file or directory)
Error executing command
[FAILED]
ciscoasa#

SOLUTION
Instead of using “wr mem”, use the following command to save your configuration to Cisco ASA in GNS3.

copy run disk0:/.private/startup-config

ciscoasa(config)# copy run disk0:/.private/startup-config
Source filename [running-config]?
Destination filename [/.private/startup-config]?

GNS3 NIO (Network Input/Output)

If you used to play around with GNS3, you’ll find the term NIO. I always wondering what is the meaning of it. Finally I found it here.

NIO is stand for Network Input/Output

There are a few type of configurations in GNS Network Input/Output (NIO) which are:

1. NIO Ethernet
2. NIO UDP
3. NIO TAP
4. NIO NULL

Thanks FreeCCNAWorkbook.com for the info.

[solved] GNS3: 206-unable to create UDP NIO

PROBLEM

Unable to to open saved topology in GNS3.

SOLUTION

Change ‘Base UPD’ from 10000 UDP to 10001 UDP.

To change it, go to “Edit” and click “Preferences …” or just use the shortcut key which is the combination of Ctrl+Shift+P.

In Preferences, go to Dynamips, and look for Base UDP setting. Default Setting for Base UDP is 10000 UDP.

Change Base UDP value from 10000 UDP to 10001 UDP and click OK.
