Ubuntu / Apple :: Connecting The Drive Via The Ide Port On The Motherboard?
May 28, 2011
- I've recently been donated a second emac by a friend that needs a new hdd. I want to add as much speed as possible, but don't know much about hdd transfer speeds
1)sub 100 SSD vs 7200 16mb 3.5'' platter drive ? I can't seem to find much information here. As far as I can tell, the standard hard drive would be faster unless I'm prepared to spend a couple of hundred on a top of the range SSD - is this correct?
2) will a sata/ide converter slow the transfer rates? is it worth spending the extra 50% to get an ide drive with the same specs as a SATA drive, or just use the converter?
3) Thoughts on connecting the drive via firewire - how much slower would this be than connecting the drive via the ide port on the motherboard? I am only concidering this as I don't use the firewire ports for anything else, and getting to the hard drive is a total pain, not to mention the inherrant risk of electric shock on these machines.

I have a seagate SATA hard drive that was running a mythtv distro. It had 3 partitions, EXT3, swap, and XFS. I started having I/O errors on boot and saw error messages on both the EXT3 and the XFS partitions. I also heard some clunking sounds on the drive when it was reading, so I thought hell, the drive is dead.
I have since replaced the drive and everything is back up and running on the replacement drive. I thought hell, the seagate drive is toast, but I just want to verify it with some sort of tool. I have the hard drive in a Vantec NexStar external hard drive case (SATA->USB) and found there was a tool called badblocks. Ran badblocks on it, which ran for 24ish hours and found no bad blocks. I also didn't notice any clunking sounds while it was running.
I ran
Code:
badblocks -n -v /dev/sdb
Is badblocks a proper test to run on external hard drives or was I just wasting my time? Is there any way that I can really test it without removing it and connecting it with SATA to the motherboard?

I bought a new motherboard and put this hard drive and 2 others on it. This hard drive has Kubuntu 8.04, one other has windows 7, and the 3rd one has Mandriva 2010. I re installed Mandriva 2010 so it would recognize the other 2 hard drives (10 hours later). And even though GRUB sees all 3 hard drive I cannot boot to Kubuntu 8.04. I had to put Mandriva on the one because it has a complete GRUB bootloader whereas Kubuntu does Not So is there a way to get this hard drive to work on my new motherboard?
I had to put together another tower with the old mobo to get to where I am now.

I have an HP 6735s laptop that I have connected an Apple Wireless Keyboard and Apple Magic Trackpad to via bluetooth on 11.04.
When I login the keyboard automatically connects via bluetooth (once the gnome-bluetooth applet boots), however, I need to manually go into the applet and click connect for the trackpad. I can then run a script to start touchegg.
How I do set up the trackpad to auto-connect? I am guessing the built-in trackpad on the laptop is overriding it?

I seem to be have issues periodically connecting to wireless networks with WPA. It'll work one minute, and then I switch my macbook back on after a period and it refuses to connect again. It's happened on and off on three different networks now.
An example of /var/log/syslog:
Code:

I am trying to connect to an apple computer wirelessly to get access to the internet.. If no encryption is used on the network (gateway?) set up by the apple computer I can connect just fine and browse the internet.
-If a WEP encryption is introduced I cannot seem to connect... even though the WEP keys are identical.
-I have tried both WEP 128 passphrase and WEP 40/128 key... -Have tried the WEP passphrase being both just numbers in case that mattered.

Using a fresh Ubuntu server install, i setup UFW :
[Code]..
When connecting from external box to this server on port 25, the connection is properly blocked by UFW but i can't find any UFW log (/var/log/kern.log, /var/log/messages, /var/log/ufw.log ...). I'm using default rsyslog.

I went and generated a self signed SSL .pem file ($1000 for a signed wildcard ssl certificate is out of my price range at the moment). I can connect to my server on port 26 when using STARTTLS but not SSL/TLS mode. I would like to be able to connect to port 465 on SSL mode, but I have no idea how.

I'm looking forward to know how to connect to a remote server through SSH but from a specific port, so I con drop connections from random ports that's not the one I choose. Is this possible?
I have tried by setting up an iptables entry to forward output through both, PREROUTING and OUTPUT (one at each time, flushing when I can see that it's not working), in NAT table, so I can connect doing ssh localhost
Code: Select alliptables -t nat -I OUTPUT -p tcp -s 127.0.0.1 -d 127.0.0.1 --dport 4141 -j DNAT --to 192.168.1.2:4040
Unfortunately, it is not forwarding as I'd like.
I want to do this because I think that doing this will enhace the security, dropping connections of clients that are trying to connect from not allowed ports. I have already set up fail2ban and created SSH keys, not allowing to login with password, only key allowed. Will only allowing connections from a specific port will enhance the security or not really?

I have been trying all day today to setup a sendmail SMTP server on our Red Hat 5.5 dev box. We have 2 network cards, 1 to the local network with a 192.168 prefix and an external card which goes out to the web through a BT leased line through a Cisco router.
First I followed one of the many helpful tutorials online to setup sendmail, installed all the required packages and made a couple of small config changes to allow the service to listen on all IP addresses rather than just the localhost 127.0.0.1.
The main change is in the /etc/mail/sendmail.mc file where I have changed the following line;
DAEMON_OPTIONS(`Port=smtp,Addr=x.x.x.x, Name=MTA')dnl
I have tried removing Addr completely, setting to either the local or external IP and then rebuilding the sendmail file using 'make -C /etc/mail' and then restarting using 'service sendmail restart'
The SMTP port has been added into the firewall and it is showing to be listening on IP 0.0.0.0:25 which I believe means it is listening on all IP's assigned to the machine, sendmail is also in listen mode and running correctly.
Finally I have changed the /etc/mail/access file to include the local IP range 192.168 and external IP range and rebuilt this into the /etc/mail/access.db file and then restarted sendmail.
Googling the error all the sites I have found talk about making sure the 'DAEMON_OPTIONS(`Port=smtp,Addr=x.x.x.x, Name=MTA')dnl' line is uncommented and not much else in terms of what else might be incorrect.
I am starting to run out of ideas on things to change or check, telnet works correctly on other ports on the same server, ie httpd for apache on port 80. I have also rebooted the server to make sure that it wasn't something odd happening.

1. Need to connect 2 CCTV DVRs and view from remote. 2. Can get a static IP address. But I dont know if this is a secure way since any once can view if the know the ip address. 3. Question is : is it possible to connect the DVR( s) to a linux server which will get user name and password before letting us view the DVR. Currently there is one set as follows: 1. From location X a device is connected to location Y using leased line and static IP (12 kms distance). In location Y a router is placed and port forwarding is configured. From Location Z using internet and remote desktop concept the device at location X is viewed and data captured. Is it possible to use a similar concept but with some sort of security authentication procedure in place.

I am trying to connect to a cisco console port using the usb to serial converter. I am using minicom and I changed me setting to reflect the USB converter cable, but it isn't working. I have set my baud rate to 9600, 8 data bits and no parity. Minicom acts as if it is connected (it doesn't give any errors), but there is nothing on the screen and nothing happens when I type. Also, I use the tail command and it sees the usb connector connected when I unplug it and plug it back in.

I've been trying to find a solution, I've looked everywhere but no luck. I have a 1TB drive, checked the cable & it's connected to motherboard SATA0. That motherboard is dual booting fine (windows7 + Ubuntu 10.04).
My problem is when I connect the other SATA drive, SATA1. Upon restarting my machine, nothing happens & I dont see any boot menu (grub).
I've checked the bios settings, boot drives are in order:
CD-ROM
SATA0
SATA1
To check if the second drive has physical errors, I've connected it as SATA0 (alone) & installed successfully windows & ubuntu 10.04. I formatted it & installed ubuntu studio. The drive is working fine. So I formatted it again, & now it's not connected.
How can I make it work? I want SATA0 to have both windws/ubuntu, & the SATA1 to be just a data storage drive.

Having become so frustrated With the many bugs in 11.04 I have stepped backward and instead installed Ubuntu 10.10 onto my Dell laptop. Until now I have been very pleased, as nearly everything has worked well, straight out of the box. So, just as I thought I was home and dry I have noticed that I cannot see my Synology NAS drive on my network. This is doubly frustrating because my other PC, also running 10.10, has suddenly lost it's ability to see the NAS drive too. Throughout last week I used the NAS in conjunction with my Ubuntu PC without a hitch but now it's gone. The NAS is visible to both Windows and Macs it's just the Ubuntu machines that cannot use it. It is also vaguely annoying knowing that the NAS itself uses a Linux OS or maybe that could be a clue to what's wrong.
As things stand my Apple Macs can see each other, they see the Windows box, see the NAS and see the shared folders on the Ubuntu machines. The Windows machines see the Macs, each other, the NAS and the Linux shared folders. The Ubuntu machines only see the Apple Mac shares, no Windows and no other Ubuntu shared folder nor the NAS.
It is curious because the little program Avahi Zero Conf Browser can see absolutely everything on my network yet the Ubuntu GUI is proving to be the most difficult thing to network using anything other than than a web browser. Is there a concise definitive reason why Linux (Ubuntu) is so infernally difficult to network? I am not very experienced with Linux or the terminal but was hoping that this system might by now have become a little more user friendly for ordinary people.
Could there also have been something in a recent OS update that has killed off my PC running Ubuntu's ability to see the NAS where previously there has been no problem.

I am running the latest Ubuntu on a partition with windows 7 as my main OS. I got my wireless drivers installed and it seems to pick up on all the wireless networks, whenever i try to connect to mine it tires and then fails and asks for the password again, even though its definatly the right password for my wireless.
I am also having trouble connecting to my external hard drive, i am completely new with Linux and would appreshiate -retard proof- tutorials if you need me to run anything, and such. Its fully updated and drivers are up to date (apparently) so i cant understand what is wrong.

I have a Macbook Pro with a b0rked DVD drive, and want to install Ubuntu on it.
I have followed the instructions here: [URL]
But when rebooting and holding ALT, I don't get the option of booting from USB.
Possibly related, when I view the USB drive in Disk Utility it's marked as "Bootable: no" :
I've tried this with two different USB sticks.
I've also burned a Ubuntu install disk from the original ISO, loaded it into another mac and started that mac in Target Disk Mode. Then I connected them with Firewire, rebooted the mac *without* the disc drive, held ALT and chose the shared disc as the boot device. Though weirdly it was named "Windows". Sadly, I then got a message on a black background saying it was not a bootable device.

I have a Ubuntu box with two drives, one of them is where Ubuntu is installed and the other one is where I store all my music, photos and other documents. I recently bought a Mac and I want to be able to access the drive where I have all my documents from my Mac. Is there a way to accomplish this? I've been looking all day for an answer to this but all I can find is how to share a folder instead of a whole drive.

rEFIt can not see my USB thumb drive during boot, therefore can't install. Tried using the dd utility to copy the Ubuntu ISO to a spare partition on my internal hard drive. Now, rEFIt sees that drive but attempting to boot into it gives me a 'Missing Operating System' message. So I'm back at trying to get the system to boot from the pendrive.

Basically I have a Macbook Air 3,1 and I decided to install ubuntu on it through the bootcamp partitioner. I installed Ubuntu 11.04 Natty Narwhal and got it up and running on the bootcamp partition (just Ubuntu - no windows) with a bit of help from refit. Here's my problem: the 2 OSs are working great but I want some integration via virtualization. I have VMWare Fusion and I think I should be able to use the physical Ubuntu installation inside a virtual machine. Near as I can tell the only problem is that I can't mount the bootcamp drive in OS X. Disk Utility sees it as a corrupt FAT32 partition and my attempts to mount it with either gui or command line are failing. Is it possible to use a bootcamp drive like this? if so, how can I mount it?

My friend has a Windows 7 desktop with a large data hard drive which is set up to allow other users to connect to remotely, such that they have read and write access. To set up a connection from another Windows machine, it is as simple as right clicking in the My Computer window and selecting "New Network Connection", then entering the information requested.
The information my friend as given me is:
- The IP Address
- The Hard Drive's Name
- A Username and Password

My new PC fails boot when having my IDE DVD drive connected. If the drive is removed the OS boots up without any issue. Once the PC is powered ON, the grub menu shows up, but when Ubuntu 10.10 is selected I get a blank screen with a blinking cursor on the top left corner and I have only option to force shutdown the CPU.ON selecting windows 7 i'm able to boot successfully and use the DVD drive without any problems.

I'm going to put Ubuntu on my thumb drive. It's a rather large drive, so I might as well make use of the extra space.
Do I format it to FAT? Never done this before. Also, how do I enable it when I boot up? Do I have to make my computer to boot from the USB drive first in the BIOS settings or is there an easier way to do it (like clicking on an icon inside the USB virtual drive on the desktop).

Drive will not read on the Mac after booting in Ubuntu!I haven't booted Ubuntu in months (October?), but no hardware changes except for the expresscard. Ubuntu runs nicely in a virtual machine from the Mac side, so I made a fresh VM with Karmic. Couldn't remember the cool apps I had running before (it's been a while), so I booted into Ubuntu to check it out. The HDD was connected and on. (Oops.)It was fine last night on the Mac. I did not notice if it mounted this morning (still in OSX, 10.6.2, Mac sleeping overnight and HDDs on for an unrelated backup). So there is a very slim possibility this has nothing to do with Ubuntu.
Back to Ubuntu, the other external (Firewire 800, HFS+) mounted as usual. Again, I cannot recall if the Fantom mounted. I have not installed drivers for the expresscard/eSATA in Ubuntu (separate driver install is required on the Mac a rarity). I scribbled down the names of the apps I was looking for, and rebooted the Mac to OSX. Where's my HD? Disk Utility sees it as unformatted, and oddly enough, SCSI. If I plug it in via USB, it simply sees an unformatted disk. eSATA is OK with another drive on the Mac.DiskWarrior failed to see the disk entirely with either connection, same in Leopard and even Tiger.Could Ubuntu have confused the partition maps or something? Any thoughts on how I might get it running before I give up and restore the backup?
