Capturing a command output from unix

Hi All
I am using enchanter to connect to unix and running a command but how do i capture the output of the command. Follwoing is the code i used.
import java.io.IOException;
import org.twdata.enchanter.SSH;
import org.twdata.enchanter.impl.DefaultSSH;
public class connect {
          public static void main(String[] args) throws IOException {
               SSH ssh = new DefaultSSH();
               ssh.connect("ip address", 22, "username", "pwd");
               ssh.sendLine("ls -lrt");
               System.out.println(ssh.getLine());
               ssh.disconnect();
}Thanks

Thnx for quick reply.
But i want to capture it in render response phase. May it will be possible??? Is render response phase is responsible for generation of HTML format?? If yes then how can we capture output coming from this phase.
URLConnection if fine but it still hit server once. I don't want that. I want to store page html format during its view preparation for html.

How to capture graphical outputs from other programs

Does anyone know how we capture the graphical outputs from the other programs and show them
on the swing?
I'd like to use a java program to run gnuplot, capture the outputs, and show them using swing.

Depends on what you mean by "graphic outputs".
Taking a quick glance at the gnuplot homepage, it looks as if you can output to PNG files, so just run the app, and load the png file.

ok, not sure how much improvement this will give in general, but its given a reliable 25% speed increase on my mini tests
using the nio libraries will also get you a lot further, and is the way to go if you are very keen on speed

It is not the problem of your program. This happens becuase of the "nature" of the excel. You need to retain the text property of that column.
Try like this:
1. Download the file in .txt
2. Open Excel .. blank sheet
3. Now, click on Open. Select your .txt file
4. One pop up will come ..."Text Import Wizard"
5. Select the fixed width or Delimited ... Press Next ...
6. Select appropriate delimitors or fixed length .. press Next
7. Select your coulumn (which has the problem), Select the "Text" radiobutton on the upper-right corner and finish.

Command output redirect question

Hi guys,
I am putting in a kron function to transfer the command output from all the switches and routers on our network to a tftp server.
I have the kron occurence and policy lists set up the way I want them and have tested the redirection of the command line output to the server.
The problem I have is that I want to back up the switches 3 or 4 times once a week to compare the configs to make sure that no unwanted changes are being made over the course of the month.
Is there a way to use a variable to change the file name when it redirects? Currently when the occurence runs the file modified time on the tftp server changes but the output doesnt append as I had hoped it would, i.e one file having the config copy in to the file over and over.
Thanks for your help

You might want to consider the built-in Config Archive feature instead of kron. With Config Archive, you can periodically take backups of your config (even to a network server), and you can adjust the filenames using either date or hostname (or both). Check out the documentation at http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/gtrollbk.html#wp1100253 for more details.
In addition to Config Archive, you also have the option of going with the Embedded Event Manager. EEM also has a cron feature which will allow you to run CLI commands periodically. Depending on your IOS version, it may be possible to do what you want using a simple EEM applet, or you might have to use a Tcl script policy. More on EEM can be found at http://www.cisco.com/en/US/docs/ios/netmgmt/configuration/guide/nm_eem_overview_ps10592_TSD_Products_Configuration_Guide_Chapter.html .
All that said, most TFTP servers have a security requirement that a file must exist on the server before one can write to it. Therefore, if you try and create new files (i.e. a new file each day), the TFTP server may reject the WRITE REQUEST unless a file with that name already exists. In light of that, you may need to use something like SCP or FTP instead.

How to Save Command Output to Flash on ASA 8.4

Hi,
I nice easy one for you guys.
How do you save the command output from the CLI to a file on flash?
With IOS, I would normally use a pipe command to redirect to tftp, but the ASA doesn't support this as far as I can tell. As a work around I was thinking I could save the output to flash and then tftp that file off the ASA.
Thanks,
Paul

Hi Jennifer,
Thanks for your help. I do use this feature at the moment, but I find every break in the output (where you need to hit space to see more) gets recorded which leaves the file quite messy. I usually have to edit the file afterwards so it reads clearly.
I wondered if there is a way for the asa to write the output directly?
Thanks,
Paul

Output from Send Unix command stalled

after send a unix command to a client the output from
the command stalls. It seems that the output is buffered
and that the final buffers are not flushed. This behaviour
is new since 10.5.5 --
Anyone know of a way to control the buffer size, when
they are flushed or to how to run unbuffered ??
ARD 3.2.2 all around and 10.5.6 all around ARD on a Quad Xenon
and clients iMac Alum

well this seems to have been a red herring --
I had not set the "linebuffering" option on the
command
the command was lapply from the radmind suite
needed to set "-i"
thanks

All files are regenerated if changed.
That goes for the .java and the .class files that are created. The jsp server checks to see if the current version is the latest. If it is, nothing gets changed or recompiled. If things are different, programs are recompiled.
Youll notice that if you have a new jsp it always takes longer the first time. Or even when you change a jsp, the first time takes the longest for the page to come up in a browser. This is because of recompiling.
Does this make any sense?

Inconsistent output from SCVMM PowerShell commands

The command above was run twice within an interval of few seconds, as you can see the Hosts/AllChildHosts properties are populated after the second attempt.
I want to know what is the reason for this behavior, are the properties collected asynchronously? If yes, what is the best way to prevent this?
I also noticed that when you open a new powershell window, the same behavior repeats, in fact you get correct output in one window, whereas you get null values in other. What is the reason for this and what's the work around?
Thanks in advance.
Mandar

There are times when you get a job back as the return value and not the actual queried value.
Quite frequently it has to do with the information being queried.
Getting a specific HostGroup I would expect to be relatively quick, however generically querying for all host groups might not.
I have not tried the specific scenario myself, I am describing behavior i have experienced.
Does this affect the reliability of the PoSh module? I don't think so. But it definately affects how you use it and its cmdlets.
I have learned that taking thinking from another virutalization environment (XenServer or vCenter for example) and expecting those same behaviors from SCVMM is a false assumption that many folks run in to. This makes VMM neither fit nor unfit - just
different.
I am not attempting to defend VMM, just stating situations that I have been in with development teams.
