OpenSUSE Install :: Logging In And Auto Connecting Wireless Access?

Sep 1, 2011

I just recently switched to openSUSE 11.4 from Ubuntu 10.10 so I am very new to this distro and Linux in general. My question is this.Is there a way to make it so that I don't have to keep entering my root password in order for the OS to connect to my wireless?Every time I login the KDE Wallet Service pops up and asks for my passwordI know that it is there for security and what not but it'd be nice if I could just login and the laptop connects to the point without needing a password every time

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.

Debian :: Connecting To SSH With Specific Source Port

May 14, 2015

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 -d --dport 4141 -j DNAT --to

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?

Software :: Sendmail - Telnet Not Connecting On Port 25?

Jan 11, 2011

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

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 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.

Ubuntu :: No Laptop Screen After Connecting External Display

Jan 2, 2010

I have tried to connect my GMA500 based Acer 751 to an external dsiplay via VGA connection. I couldn't get the right resolution on the external screen (1920/1080) so I disconnected it and rebooted. Now there is only an "unknown" screen in the display menu. I have rewritten the xorg conf file per instructions for enabling GMA500 but to no avail - conf file looks right but screen is "unknown", low resolution and 4:3 aspect ratio, instead of 16:9. How to restore to laptop monitor - I think I can take from there to enable the right resolution.

Ubuntu Networking :: Connecting To External USB Hard Disc?

Aug 30, 2010

I have a few computers all connected to the same router both wireless and wired. All at the moment are running Ubuntu. There is no problem sharing any of these computer's local drives through the network. However I have one desktop with an external USB Hard disc plugged into it. I would like to share this external hard disc on the network. I set it up to share but when I try and access it from one of the other computers on the network, although it shows up, I get the message "Unable to mount location. Failed to mount windows share".

Ubuntu :: Connecting External Monitor Causes Interior Shadows?

Nov 27, 2010

I'm using a netbook, and I thought I'd connect a monitor I had in the closet and see how things went. I can get a decent multi-desktop setup working, but it comes with an unusual side effect. I don't know if it's of any significance, but these weird shadows appear on all windows, menus and panels. I deativated any Compiz effects I thought might be arcing up, but that didn't seem to do anything.

For what it's worth, I tried this monitor in KDE and it seems to work fine. Netbook Edition promptly soiled itself and went into deep shock with the monitor plugged in, however -- both screens flickering, Docky spasming out of control. But I digress! The netbook is a HP Mini 210 and I believe this monitor is a Mitsubishi Diamond View DV173.

Ubuntu :: System Lagging When Connecting External Monitor?

Dec 31, 2010

Just installed Ubuntu 10.04 LTS netbook edition and everything goes well except for one thing.

When I connect my lcd monitor to the vga port the system lags. If I listen to music and browse web pages at the same time, the sound skip and when the page stop loading, music is ok. Also, the mouse skip. If I do circle with it on the desktop without doing anything else, it will skip.

The strange thing if I remove the external monitor and reboot the system everything comes back to normal.

I had Intrepid Ibex for 2 years without any problems. I remember a post saying that powernowd should be disable, but can't find the process from the startup list anymore.

Server :: Connecting CCTV DVR To Router With Port Forwarding?

Jul 30, 2011

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.

Networking :: Connecting Mybook 2 (external HDD) With Laptop Running Ubuntu 10.04?

Jun 3, 2010

im having problems connecting mybook 2 with my laptop. Everything was ok and running perfectly and there was no changes in my laptop or upgrades and it stop working. I was not able to see the computers in my network then I fixed it I can see them but when I try to browse the files the OS tells me that is unable to mount location and failed to retrieve share list from server. The funny part is that if I go to Places>Connect to server and type my mybook ip address, my laptop can connect and I can browse the files. I really dont know what is the problem. My firewall is down so I dont think that is the problem. If anyone can help me with these because I know im able to connect to my mybook but i am unable to connect to any other laptop or my WD-Tv live.

Fedora :: Connecting Cisco Console Port - USB To Serial Converter

Dec 16, 2009

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.

Ubuntu Installation :: On External Drive Through The USB Port On 9.10

I have windows on my internal drive on a dell D 800. I removed the drive and installed 9.10 on an external drive through the USB port. It works great, until I put the internal drive back in. With the F12 button on startup, and choosing the USB device to boot from, I get a grub recover>. If I remove the internal drive it boots fine with this method. I don't want to have to remove the HD each time. Do you have any idea what to do? Is there a command I can enter at the grub recover prompt?

Ubuntu Servers :: Syslogng Installation For Centralized Logging

Jan 29, 2010

I need to centralize the logging of several machine on one machine with syslog-ng.I'm currently using fail2ban for security enhancement and logwatch for log reports, which are based on file log on each machine. is it possible to keep local logging for fail2ban and logwatch (logwatch can be dropped, but not fail2ban). One other need is to move old logs to a ftp site for archiving, as in france we have to keep one year of logs.

Another thing I've seen, is that logging goes to a MySQL database instead of the filesystem which allow to have some nice feature as web frontend, search capabilities.how is it compatible with the ftp save?
