awk and cat - How to ignore multiple lines?

- by Filipe YaBa Polido

I need to extract Voip log from a D-Link router, so I've setup a little python script that executes a command in this router via telnet. My script does a "cat /var/log/calls.log" and returns the result, however... it also sends non-important stuff, like the BusyBox banner, etc... How can I ignore lines from 1 to 6 and the last 2 ? This is my current output: yaba@foobar:/stuff$ python calls.py BusyBox v1.00 (2009.04.09-11:17+0000) Built-in shell (msh) Enter 'help' for a list of built-in commands. DVA-G3170i/PT # cat /var/call.log 1 ,1294620563,2 ,+351xxx080806 ,xxx530802 ,1 ,3 ,1 DVA-G3170i/PT # exit And I just need: 1 ,1294620563,2 ,+351xxx080806 ,xxx530802 ,1 ,3 ,1 (it can have multiple lines) So that I can save it to a CSV and later to a sql db. Thanks, and sorry my bad english.

HP Proliant ML115 G5 - Boot order lost after reboot

- by Filipe YaBa Polido

I have one HP Proliant ML 115 G5 (AMD) with the latest BIOS (07-06-2009) and recently I've installed an USB disk. This is a common problem on old Proliant servers. When you plug the USB disk, BIOS boot order changes and tries to boot via USB. So, I'll change the BIOS settings and make the SATA disk the default boot device. The problem is, when I need to unplug the usb disk, and plug it again later. I can't be always changing the BIOS settings... How can one solve this for ever?!?!

Problem with Outlook 2010 (SMTP AUTH LOGIN)

- by Filipe YaBa Polido

**IGNORE THIS QUESTION - SOLVED WITH A PYTHON SCRIPT available at: http://yabahaus.blogspot.com I have to connect one customer Outlook 2010 to a remote server on which I have either no right, neither way to talk to the sysadmin. This is the thing, after installing and reviewing the logs on Wireshark: Outlook Express: HELO machine AUTH LOGIN username base64 encoded password base64 encoded mails go through. Outlook 2010: HELO machine AUTH DIGEST-MD5 response from server Outlook sends just a * AUTH LOGIN password base64 encoded So... I can send mails in the same domain, but can't send outside, it gives me a relay denied message. My point is... Why the h**l Outlook 2010 doesn't send the username AND the password?! It can never login the right way :| With other versions of Outlook it works fine, and with OE works great, it auths and allows to send mail to a different domain. I've googled and nothing worked. I'm pretty sure that I'm not alone with this one. My last resort will be to configure a local proxy/server that relays to the original one :| Any help would be appreciated. Sorry my bad english as is not my natural language. Thanks.

Comunication from Server to Client + Client LAN

- by Filipe YaBa Polido

I'm having some trouble with some network setup. I've tried OpenVPN, SocialVPN, Hamachi, still it is not working. This is my setup: Server A: NIC 1 with internet public address, NIC 2 to LAN Client B PC: NIC 1 (192.168.10.2) connects to router 192.168.10.1 Client B Device: 192.168.10.3 (Configured via software, can't do much here) Problem: Server A must connect to cliente device B. (I can install software needed at Client B PC). However... I can't change the router to some model with VPN like Draytek or Cisco :( OpenVPN fails at bridging, PC B can ping Server A, but Server A can't ping Device B, only PC B. What else can I do?!?!?

How to catch all exceptions in Flex?

- by Yaba

When I run a Flex application in the debug flash player I get an exception pop up as soon as something unexpected happened. However when a customer uses the application he does not use the debug flash player. In this case he does not get an exception pop up, but he UI is not working. So for supportability reasons, I would like to catch any exception that can happen anywhere in the Flex UI and present an error message in a Flex internal popup. By using Java I would just encapsulate the whole UI code in a try/catch block, but with MXML applications in Flex I do not know, where I could perform such a general try/catch.

Synchronous dialogs in Flex?

- by Yaba

How can I open a synchronous dialog in Flex? I need to call a function from an External Interface (JavaScript) that will open a simple dialog in the Flex application and returns an value according to the button the user has clicked (OK/Cancel). So it should by a synchronous call to a dialog, i.e. the call waits until the user has closed the dialog like this. //This function is called by JavaScript function onApplicationUnload():Boolean { var result:Boolean; result = showDialogAndWaitForResult(); return result } Does anybody know how I can do this? I could write a loop that waits until the dialog has set a flag and then reads the result to return it, but there must be something that is way more elegant and reusable for waiting of the completion of other asynchronous calls. EDIT: Unfortunately a callback does not work as the JavaScript function that calls onApplicationUnload() itself has to return a value (similar to the onApplicationUnload() function in Flex). This JavaScript function has a fixed signature as it is called by a framework and I cannot change it. Or in other words: The call from JavaScript to Flex must also be synchronous.

Flex: Prevent scrollbar from covering content when automatically displayed.

- by Yaba

I have a canvas in Flex that shall be able only to be scrolled in vertical direction, so I set the attributes of the canvas as follows: verticalScrollPolicy="auto" horizontalScrollPolicy="off" The problem here is that the vertical scrollbar covers the content when it appears - altough there is enough horizontal room left. I would have expected that the content size would have been automatically adjusted. When setting the vertical scroll policy to "on", no content is covered also. In case I set both scroll policies to 'auto' I also get a horizontal scroll bar just for scrolling to the area that is covered by the vertical scroll bar. Is there a workaround how I can relayout the content of the canvas when the vertical scroll bar is shown so that it does not cover any content?

Activate different Maven profiles depending on current module?

- by Yaba

We have a multi module build with modules using different technologies, like Java and Flex. Is it somehow possible to activate different profiles based on the module that is compiled currently? I tried it with an activation like <profile> <id>flex</id> <activation> <file> <exists>${basedir}/src/main/flex</exists> </file> </activation> ... </profile But it didn't work, although the use of ${basedir} is documented in the Maven documentation (this is a bug in Maven). Is there a different possibility to have different activations based on the current module? Or does Maven only allow to activate a profile for all modules or not at all?
