Send configuration file to Cisco router

Where can I find a C programm that send configuration file to Cisco router from linux workstation?

I wonder what kind of config changes you are making and whether that may have an impact on SSH. For example if you change the host name or change the domain name then the keys need to be regenerated.

Edit configuration file saved in router/switch flash? (IOS)

Hi guys,
I hope it is possible to edit configuration file if we have it in our switch/router flash memory?
Something like "nano" or "vim" on unix? Maybe you know any hidden commands to do this?

Cisco routers and switches store (at least) both the startup and running configurations in memory. You edit the running configuration using Cisco's built-in command line interface when you change from EXEC (enable) mode to config mode. There is no built-in Unix type editor. The commands available in config mode vary according to the platform and OS image you have loaded. There are literally thousands of pages of command references out there explaining them all.
When you complete your configuration tasks and drop back into EXEC level, you normally synchronize the running and startup configurations ("copy runnning-config startup-config" or simply "copy r s"),

Configure ATM on cisco router 1841 for PPPoE

Hi Geeks,
I have searched the net with answers but still no success to achieving what I needed.
My scenario, I 'am replacing my Netcom with a cisco 1841 router. Now, I need advise or better guided steps on how to configure my ATM interface for PPPoE to connect to my ISP network. With the netcom its easy since its uses GUI and connection picks up automatically as long username and password are correct to connect to ISP.
Appreciate any help here?
Thank you.

from the sounds of it you purchased a '4 port WAN Interface Card' to be put into your router.
(the HWIC4 cannot be used to create a 'DMZ' as you require; you will need additional Ethernet interfaces, not WAN interfaces)
a few things first...
1) yes you have increased the routers ability to serve more than one network. with an HWIC4, you can configure upto 4 more WAN segments that the router can route for.
2) if you had a 4 port Ethernet Card, then you could configure each interface to act like a DMZ, but without proper security in place, it will not be much more than a 'hop' from one network to another.
NOTE: you need to build very detailed, granular access lists to filter traffic if you wish to have any chance of provding the slightest amount of security to your inside users & hosts.
(a firewall will provide you better security control and DMZ definition and is a recommended best practice for the solution you're looking for)
your DMZ definition says it all, "...subnet between a trusted network and an untrusted network..."
firewalls inherently provide a 'trusted' interface, an 'untrusted' interface and one or more 'less than trusted' or DMZ interfaces.
routers do not inherently provide this type of security segregation. you should be using a firewall to provide your solution and security in this case.

Bad Characters writing an output file from CISCO router

Hi,
I'm making a backup of an accessrouter using telnet. I want to create a log file,so I redirect the stdout to a file this way:
System.setOut(new PrintStream(new BufferedOutputStream(new FileOutputStream("c:\\Maint\\Operator\\accounting\\accounting.txt")),true,"US-ASCII"));
When I use the monitor as stdout there are no problems, but when I do the redirection, some extrange characters appear in the log file:
AccessRouter#
copy system:running-config tftp://10.1.3.34/Maint/Operator/Backu$:running-config tftp://10.1.3.34/Maint/Operator/Backup /tempo/Baonfig tftp://10.1.3.34/Maint/Operator/Backup/tempo/Bac kup/BBDDa://10.1.3.34/Maint/Operator/Backup/tempo/Backup/BBDDan dEquip/1334/Maint/Operator/Backup/tempo/Backup/BBDDandEquip/13_
I don't know where's the problem,
Please help !
Thank you in advance. Best Regards.

What are you using to view the file? What happens if you use the default encoding instead of US-ASCII? It looks to me like either the application you are using to view the file can't interpret those characters or there are characters in the stream that don't convert well to US-ASCII.

Configure a Cisco router with Username and Password.

Hello Guys,
Am quite new in cisco and i need to configure an 891 cisco router,can someone please show me step by step configuration commands for configuring Username and Secret Password.I would like the router to ask for "Username"and " Password" anytime i want to login the router through telnet.I also want to know if i have to erase the default configurations on the router first, before i start the configuration,and how it should be done in other not to loose the router whiles working on it.Thanks for your usual quick responds.
Regards,
Eben.

Hello Eben,
Peter has suggested to use SSH because of the fact that telnet data is sent in clear text, so someone with the right tools could easily find your password and your device could/would be compromised. It is security best practice. SSH is encrypted.
Technically speaking you do not need to change the hostname / domain name. But majority of Cisco documentation follow this method.
In case you are interested on how to do this without change... see below.
Router(config)#
Router(config)#crypto key generate rsa modulus 1024
% Please define a hostname other than Router.
Router(config)#crypto key generate rsa modulus 1024 label CISCO
The name for the keys will be: CISCO
% The key modulus size is 1024 bits
% Generating 1024 bit RSA keys, keys will be non-exportable...[OK]
Router(config)#
*Jul 11 13:27:51.431: %SSH-5-ENABLED: SSH 1.99 has been enabled
Router(config)#
The normal cases just as shown in Cisco documentation, the parser (without a label on the crypto key) would force us to change the hostname, create a domain name. I think the domain name is there to put a label on the keys.
Router(config)#crypto key generate rsa general-keys modulus 1024
% Please define a hostname other than Router.
Router(config)#crypto key generate rsa
% Please define a hostname other than Router.
Router(config)#hos
Router(config)#hostname ISR
lexnetISR(config)#crypto key generate rsa general-keys modulus 1024
% Please define a domain-name first.
ISR(config)#ip domain name net.com
ISR(config)#exit
ISR(config)#crypto key generate rsa general-keys modulus 1024
The name for the keys will be: ISR.net.com
% The key modulus size is 1024 bits
% Generating 1024 bit RSA keys, keys will be non-exportable...[OK]

How to configure IPS 4240 - K9 to send log file to syslog server

I am looking for the commands in how to configure IPS 4240-k9 to send log file to SYSLOG server. If anybody has or came across similer issue please advice.
Thanks in advanced.

Ali -
I am sorry to tell you, but the Cisco IPS Sensors do not send Syslog messages. Your only options for sending signature event information are:
SDEE (an TLS Encrypted XML formatted message) the sensor is the SDEE Host and your event receiver (MARS, IME, Intelitactics, etc) is the client.
SNMP Traps - You need to set the "Action" on each signature you want the sensor to send a trap.

How to configure one dsl connection and one public ip in cisco router and map to one interface for using exchange server

how to configure one dsl connection and one public ip in cisco router and map to one interface for using exchange server

Hi ,
Have you got any additional public IP Address from your service provider , If yes on router you can have static route for those additional IP Address pointing to your ASA outside interface .
Accordingly you can configure NAT

In my Scenario i want to configure file sender Adapter.But in Parameters

In my Scenario i want to configure file sender Adapter.But in Parameters, for Adapter Engine Column It Shows blank,Integration Server will not appear for that column.Finally It Gives Error- Adapter Engine is not Defined.
What is the Reason for this...
Please Clarify ASAP...
Thanks..

Hi Chiru,
      It seems that you may have missed some steps while doing the configuration. After doing all the activities in SLD and IR and activating all the components created in IR it should work.
      Plz check that you have selected as Adapter Type as File and correct namepace in the next field. Transport Protocol as File System (NFS), Message Protocol as File and I hope after all these information you will get Integration Server in the Adapter Engine field.
    If the problem persists please revert back.
Warm Regards,
Subhasha Ranjan

RFC Sender configuration : RFC - XI - FILE

Hi All,
I read the post at RFC Sender Configuration in Asynchronous Mode and I have the same problem for the configuration.
I want to do a simple asynchronous RFC scenario ( RFC -> XI -> FILE) but I keep getting errors. Do I need to create a BPM to make it work? I'm using XI 3.0
Thanks

Hi,
For RFC to File Scenario, if you will be calling the RFC from any ABAP report then the import parameters will be passed to File.
Here you can use the Concept of Dummy RFC as below.
Lets say RFC1 --> Original RFC
RFC2 ---> Dummy RFC
1. Create one Function Module (RFC 2) in which take the import parameters similar to the RFC -1 Output parameters.
2. Now in ABAP report call the RFC-1 and get the Output in export parameters and pass it to RFC-2 as import parameters.
3. In XI import RFC-2 and map the import parameters to the Receiver File.
SO your purpose to pass the Output of RFC-1 to file in async way will be resolved .
Thanks

Configuring wireless on cisco 877w router

Hi all
I have a Cisco 877W wireless/ADSL router and having great difficulty with configuring wireless on this router. Here is a quick summary.
1. The ADSL is configured to obtain public IP from the ISP
2. Default interface vlan 1 is configured with an IP address
3. I went into vlan database, tried to configure multi vlans and the router prompted me that it can only have max 2 vlans. Hence what's the use of up to 16 different SSID using wireless?
4. I've setup DHCP scope on the router to give out IP address to clients (both wireless and wired)
5. I'm able to configure WPA-PSK on the router and was able to connect wirelessly to the router but I won't be able to obtain an IP address from the router
6. There are two scenarios that I'd like to do:
A. Setup wireless to connect to the same subnet as what's on vlan1
B. Setup wireless to connect to a different subnet to vlan1
For the life of me, I could not find docs on Cisco web site that shows me how to exactly this. I found some documents that use interface F0 as a trunk port and treat the interface Dot11Radio0 with sub-interfaces. I don't connect this router to a switch (standalone router) so how can I do this? Please point me to some docs.
Thanks in advance for your help.

My configuration works for wireless no authentication, but failed for WPA-PSK:

After I configured the same wpa-psk key on the XP computer using windows zero configuration and tried to connect to the wireless work, I got the following errors on the router:

*Mar 1 03:00:52.623: %DOT11-7-AUTH_FAILED: Station 000c.f123.25cf Authentication failed
What could be wrong? Thanks!

How can I programmatically send a configuration file to an RT target?

I'm creating an XML configuration file on the host with a configuration VI. This allows me to parameterize the app VIs to allow changing the number and allocation of ports, controls, and indicators. The configuration file is used by both the host main app VI and target VI. When the operator clicks the save button on the configuration VI that exports the XML file, I'd like it to automatically transfer the file to the RT target (a PXI). How can I do this?
I saw that there is an Internet Toolkit that provides FTP, but I have a hard time justifying $500 just to copy a file over. I suppose I could flatten out the XML into a string and send that to the target when the app starts rather than send a file. Any better ideas?
Keith.

Hello,
You can also use the FTP Put File.vi to programmatically transfer a file to your Real-Time Target, however, for this you will need the LabVIEW Internet Toolkit.
