I'm having difficulty switching from GUI to console mode. I use ctrl-alt-f1 and the screen goes blank and I see a flashing cursor but I'm unable to do anything. I can switch back into GUI mode using ctrl-alt-f7. Also at times I see the word Ubuntu with 4 dots and 2 of them are orange if that's of any use. Like the initial boot loading screen.
I've tried going back to the default display drivers and that hasn't solved it. I'm using a CRT that's connected up to my display card via a VGA > DVI converter. *I've just checked and I can't get into recovery mode either
I've successfully install kvm with private network (nat) up running. I want to switch the kvm network using bridge mode (or host-interface), but do not success. env: nic iwl4965/ kernel 2.6.27.8/ debian etch upgrade to lenny/ kvm 0.9.1/ hardware hp 6910p The doc I follow up is at [URL] The way how i set it up is to modify /etc/network/interfaces by adding following section to enable br0
Code:
allow-hotplug br0
iface br0 inet dhcp
bridge_ports wlan0
bridge_fd 9
[code]....
However, the problem is the guest os, which starts with -hda k1.img, can not access to the internet. Is there any step I miss? or it is because wireless does not support bridge (I've heard doc says that wireless does not support wireless bridge)?
I am working on development of an TOS that runs in Protected Mode. I am required to switch it from text mode to graphics mode. Everywhere I google I get only one solution set AX to 0013h and call INT 10 and easily the VGA Graphics Mode is set.
I am working in protected mode and hence cannot use INT 10. Can someone please guide me? I came across a post where it was said that this can be done by setting the VGA registers, but I could not understand much from the link provided in the post on how to implement it.
I recently hooked my television up to my computer as a second monitor so that I can watch videos on it. However, I don't always want to be in dual monitor mode. I've found that running "gksudo nvidia-settings" allows me to switch between the two modes without restarting X if I change some settings around and click "apply".
Is there a way I could setup two scripts to handle this process? The main problem I'm encountering is the fact that I change all the settings through the nvidia-settings graphical interface; therefore, I have no idea what's actually happening behind the scenes, so I don't know how to go about putting the two scripts together (what commands to issue, etc.).
Since 13.37 I notice that vi needs the 'home' key to switch from input to command mode. I think this is only when I connect via Putty to the machine. When I am on local console it is still ESCape like it used to be. Does anyone know how to set it so that vi will switch from input to command mode using the ESCAPE key when using Putty?
Another vi question :
When you edit htm files, vi goes automagically into some sort of html display mode. Ofcourse I never want that since all I do is edit the html in vi. So I need to go to command mode and type :normal everytime I want to edit html files. Where can you configure that vi (or vim) default to normal mode always?

I recently migrated from Gentoo Linux to openSuSE because I no longer have that much time to maintain the sane state of my system, and want my computer to just work when I need it.. So far openSuSE surprised me and I was able to configure my system almost completely without even touching the shell where I almost lived in the Gentoo days..
However, I'm not able to make openSuSE automatically detect my logitech BT dongle (as part of a dinovo keyboard and mouse set) and switch it from HID to HCI mode so I'm able to use bluetooth.
What does work is this:
Code:
# /usr/sbin/hid2hci --method=logitech --vendor=046d --product=c70c
Then the dongle is switched to HCI mode, a bluetooth applet appears in gnome and I was able to pair with the keyboard, keypad, mouse and mobile phone
But I don't want to manually run that command each time, so I figured the best way is to let udev handle that (?).. As I didn't find any udev rules to perform such an action I tried creating one myself, however, I'm not sure that I'm doing it right /etc/udev/rules.d/70-hid2hci:
Code:
ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[345abce]|c71[34bc]", RUN+="/usr/sbin/hid2hci --method=logitech --vendor=$attr{idVendor} --product=$attr{idProduct}"
But that doesn't seem to work..(yes I reloaded the udev rules using udevadm)
how do I make this work? And shouldn't it already work out-of-the-box?

How do you interface with the Linux I2C driver from kernel space? For example, if I had LEDs connected to a GPIO expander on the I2C bus, how would I blink them twice before going down for reset from machine_reset()?
Essentially, I believe I need to call the functions i2c_smbus_write_byte(), i2c_smbus_read_byte(), etc. But these functions require I2C client data that I do not understand how to supply.
I am writing a code which communicates between 2 processes created by fork() statement. Parent reads a file and write the data into a shared memory and sends a signal to the child.

I have been able to use bash to initiate a google seache via firefox. I would like to either copy the source page to a file via wget or send firefox short cuts to the other terminal's firefox search page to put the html file in a directory.

The Server in the above diagram can be accessed by Client3 and Client4 but not at all by Client1 or Client2. Router0 specifies the Server as a DMZ Host. I would be more specific but this is not my server. I don't use a DMZ, I forward ports when they are needed. In this case I represent ISP1 and the server belongs to a befuddled client. Client1 & Client2 can send packets to each other, no problem. Could the DMZ be breaking communication between the Server and Clients 1 & 2?
I was going to upgrade apache from version 1.3 to version 2.2.15 on a test server (and later on prod servers).. i prepared really good for it by reading upgrading information, changes from 1.x - 2.x, read module documentation to check if any of the used modules had any different syntax and if it was supported for this new version of apache. Later i finally installed apache, upgraded all the used modules to be apache 2 compatible and everything seemed to go smooth. I started apache and resin and everything looked fine, the syntax was OK and everything so i reported back that it was ready.. but i got a feedback that the people that were going to use the server only got a proxy error or service unavailable error when apache was trying to send requests back to the backend resin server.. and this is the problem. I could just have told you that this was the problem, but i find it to be much easier if you have a little background information first to explain how the problem aried.
A couple of other people and myself has done quite extensive troubleshooting on this, we troubleshooted apache, mod_caucho and resin by themselves to check if it was any problems with them.. we could only find that mod_caucho didnt seem to behave correly, the caucho-status page was displaying an empty list of requests and what would be proxied back.. we are running the same version of mod_caucho and resin to be sure it would be compatible with eachother and all the software is running in 64-bit, only a 64-bit CentOS 4.4 OS (yes, the OS is really old but because of complications we are not ready to upgrade it yet).
When we try to telnet to the port where resin is listening its open and resin returns an X when you hit enter (like it should and says in Caucho' official troubleshooting tips). We have tried installing apache 2.2.11 instead of 2.2.15 and other versions of both resin and mod_caucho. Other modules has also been tried like mod_proxy to send the requests back and also the rewrite module with the P flag.. although this was not the preferred way to do it we only wanted to see if it had any difference which it didnt.
So after several hours of troubleshooting we are still not able to find the cause of why we are getting a proxy error (http 502) when apache is trying to send a request back. We have checked all the logs for apache and resin, we have also compiled the mod_caucho module with the "--enable-debug" option to get more verbose information but we didnt get any additional information this way eventhough we should according to Caucho' official site.
We have looked into both the resin and apache config and tried both ways of configuring mod_caucho.. and nothing seems to change the result.. we only get a 502 proxy error. So since it didnt work i downgraded to apache 1.3 one day and that was fine.. then it was upgraded again to apache 2.x to try to find out what the problems were but again we didnt find this.. so i was going to downgrade it again, but this time on a different test server, but after downgrading i for some very weird reason got the same proxy error i had when using apache 2 which is beyond my comprehension.. i just cannot understand this.
- has anyone had any similar experiences with or without the same setup ?
- does anyone know about any solution to this of can provide any additional advice on what to do further? Yes, we want the functionality in apache 2 so we will not settle with apache 1.3.. one of the features being the new filters to be able to capture requests for pre and post processing before they hit other modules.
I am moving some code for to work with SPI interface from windows to Linux SUSE platform and for to make it working I have to communicate with some small SPI driver.
I have few libraries generated by that driver:
libi2cbrdg.a
libi2cbrdg.la
libi2cbrdg.so
libi2cbrdg.so.1
libi2cbrdg.so.1.1.0

But still as u see I have some functions missed I know that they are in these libraries.
I would like to send struct data from process A to process B but I dont known what is the best way. I have read about IPC, but there are a lot of ways to do it.

My setup is as follows,
Machine-1
- Two network interface cards on same network with different MAC say MAC-1 and MAC-2
- IP 10.209.193.130 and 10.209.193.131
- Firewall IP tables empty iptables -F
Machine-2
- One NIC with IP 10.209.193.135
switch
- both machines are connected to common switch and can ping happily.
Problem:
when I send ping request from Machine-2 to Machine-1 arp tables are initialized for IP MAC pair. Surprisingly both IP are get resolved to one MAC i.e MAC-1. general observation is, MAC of first interface which has route in kernel route table. I cross checked this on Suse11 and RHEL5 same result. but In suse10 I am getting expected behavior [i.e IP1-MAC1 and IP2-MAC2 pair in arp cache]. Do any one know why kernel is using same NIC for two different interfaces?
