Ubuntu :: Tried CoLinux, Which Requires Admin Access, And Portable Remix, Which Gives Some Unnecessary GUI And Slows The Computer Down?
Feb 14, 2010
This isn't an Ubuntu question as much as it is a general Linux question, but is there a text based Linux emulator (preferably BASH) similar to DOSBox?See, I need GAS, Gnu Linker, gdb... pretty much everything in binutils, as well as a platform to test my programs at school, which runs Windows. I've tried VirtualBox, VMware and QEmu; QEmu is a b**** to access any files outside of the VM, VMware is hard to get portable, and all 3 require administrator access. I've also tried CoLinux, which requires admin access, and PortableUbuntuRemix, which gives me some unnecessary GUI and slows the computer down

I have OpenVPN setup and running on my home server (Lucid Lynx). I move around alot and use Portable OpenVPN to connect to my home server. The problem is a lot of the computers I use I do not have admin rights to install the necessary routes to connect. So my question is this. Can OpenVPN be configured to use PPTP protocol? Because I have PortableVPN on my U3 flash drive and that VPN client does not need admin rights to run. If OpenVPN cannot do this, and from my understanding of its archetecture it cannot, but I must admit i am no authority on the matter. Can you suggest a workable solution, ie. install and setup this server software and use this portable client software.

I downloaded a driver for my printer today and I opened it in the terminal. Then a window popped up saying "This opporation requires root (administrative) privileges. Please enter the administrative password below:" I typed in the same password that I use when authorizing the installation of programs from the Ubuntu Software Center and I tried it multiple times. Each time, it rejects the password. I even tried downloading something else from the software center, just to make sure the password was correct, but the system had no problem with the password when downloading from the software center. So, is my software center password different from my administrator password?

About a week after installing 11.04, I started noticing that my computer basically locks up after leaving it for many hours. When I come back, I cant get any programs to respond. I click on Firefox and it takes about one minute for it to finally respond. If I try to launch Konsole, it locks up too. But suddenly all programs start responding at the same time, after about one minute.
This is very frustrating and I just feel the problem is zeitgeist. Of course I am not sure because I cant even run System Monitor to check the problem since I cant run any apps for about a minute. By the time I run System Monitor everything is working again.

I didn't notice it before i installed compiz fusion, but perhaps it was happening then as well because i didn't play with fedora too much, but -- my problem is that after i open a few windows and a few minutes pass the entire system bogs down to what seems like 1 frame per 20sec. i can't even forcequit out of applications, and if i do it doesn't solve the problem. I read somewhere that GNOME might be trying to connect to the internet and hanging? ...

I'm new to Fedora/Linux trying it out because I'm becoming hacked off with Windows taking so much time to do anything. The problem I have is that every now and again the computer slows down so drastically that the mouse movements are jerky, response to clicks/key inputs take about 2-3 mins to get a response and the only solution is to press and hold the power button. I'm running a Packard Bell Dot M/U. It has mobile celeron 1.3GHz 64 bit, 3GB ram. Intel wi-fi, atheros LAN (i think), HDMI output. I believe that it is v similar to an Acer Aspire 1410 (but not 100% same).

I am currently running 11.04 on my laptop. Firefox is struggling to cope with images for some reason. Whenever there are pictures on screen in firefox the computer slows down to a glacial pace.
I tried clearing out the history and cookie files, and i have tried uninstalling and reinstalling FF but the problem still persists. I have tried other browsers that worked fine with images, but didn't find any that i really liked.

I have a perl script which was written for me by a professional (I have some basic knowledge), is working fine at the moment but on moving it to a different server as I'm changing a server (new server is shared and supports perl modules), I get the following message"Global symbol "$psid" requires explicit package name at admin.pl line 16". I get this for every single one for my values for the whole script which is about 2000 lines. Same error messages for main and admin.I haven't changed anything on moving it to the new server apart from the first line which is the location of the perl.I thought it would be too much to post the whole script here but anyone has any idea why is doing it taking into account that it works on a different server?

I have three computers in my network, but two will be mentioned. Computer A is a Linux Mint 9/Windows 7 dual-boot, and I have just installed Mandriva Free 2010.2, which I will call Computer B.
Now my main problem is that Computer B, while it can see and access Computer A's shares as well as the third computer, the aforementioned computers cannot access Computer B. The message was: "Unable to mount location/Failed to mount Windows share." Now, the SMB protocol was used because of the third computer and Computer A have Windows OSs installed in them.
What I originally wanted was that I can share Computer B's NTFS partition, namely Documents and Downloads, to the other computers. And I can't do that, because of the error message.
What I can do, however, is use Computer B to view shares from the other two computers (Computer A, as an example). By my experiences in Linux Mint, I understand that I'd have to mount my Windows partitions in order to share them. I don't even know if my NTFS drive in Computer B is mounted, though that is what was described.

When trying to connect to another Ubuntu machine running remote desktop using vinagre, I get a black screen on the client machine. Annoyed, I went upstairs to check the host machine, and it is waiting for me to authenticate my keyring. Why would the host need to authenticate for me to access it remotely?

I am using Ubuntu Studio 10.04 LTS and I am experiencing the following problem: my computer loses its Internet connection and appears to require several reboots to re-establish an Internet connection.
As suggested on a similar post relating to wireless connection loss, I supply the output of sudo lshw -C network
*-network
description: Ethernet interface
product: NetLink BCM5789 Gigabit Ethernet PCI Express
vendor: Broadcom Corporation
[Code].....
Note that I have REMOVED my wireless card in case there was some kind of hardware conflict or failure. I am using a wired connection through a Linksys WRT54G router that is supplying an Internet connection to another computer and an IP phone without any problem.
When I run the command network-admin (or select System > Administration > Network) I can see only 3 tabs (General, DNS and Hosts) It seems that the Connections tab has disappeared (and I believe this happened when I upgraded from Ubuntu 9/Karmic Koala). If I click Help it shows me that there should be 4 tabs, not 3.
The connection dropping began prior to my decision to upgrade. In fact it took several attempts to complete the upgrade. Should I attempt to re-install the upgrade? I am not sure how to do it without losing my connection. When I visit System > Administration > Update Manager, I am informed that my system is up to date.

I have Linux computers that are often on client networks inside firewalls . They have access to the internet but I can't access them directly. I don't want to have to get the client to mess with NATing , etc . I have written a system that uses XMPP to allow me to send commands to the computers and run simple console commands which often time is enough. These are things like run a report and ftp up to server, restart a process, give me a process list. It works OK, but some networks even block this (Googletalk is not universally loved for some reason)
I am wondering if there is a prebuilt system that allows me a computer inside one firewall (say a standard adsl modem created one) communicate in some way with a computer inside a network created by another adsl modem. I could see some sort of console like logmein or pc anywhere but as much as I have looked I can't find anything. I have considered writing a cheap and cheerful system in http or even a TCP system using asyncore in python but there must be something existent. I have a server on the web that could be used as an intermediary, relay type thing. Basically some sort of chat server for consoles is what I am thinking about. Is there some sort of SSH voodoo that I could bridge/tunnel/vpn through.

I have a CentOS dedicated server running ProFTP. I have created user accounts which are meant for FTP access only but the users cannot connect to the FTP unless their shell access is /bin/bash
Here is an example line that is outputted when I use this command:
This user can access the FTP fine, but he can also access SSH which I don't want to allow him to do. If I set his shell access to /bin/false then he can't connect to the FTP.
What can I use in instead of /bin/bash to allow FTP but don't allow SSH?

While messing around with file permissions and ownership of /var/www/ i seem to have locked myself out of being able to administer users on my 9.10 system.
when I go to the user administration screen in the icon with the keys is grayed out. with the message "not authorized to make changes". My account seems to have lost admin access. But, I'm the only user on the system.
I presumed I somehow changed my group status from the root group to something else
but, sudo usermod -g root [my name] just returns "no changes made"
All I can do for now is run as the su from the terminal. Is it possible to log into gnome with a root account?

I'm trying to set a kickstart DVD for automatically installing Fedora 10 without touching the existing data partitions on our systems. I've got a kickstart file that works great from a kickstart server however I'm having issues with creating an unattended kickstart DVD. I've attached a copy of the kickstart file from the DVD. For some reason even though all the packages we are installing are on the DVD, anaconda always attempts to connected to the internet to get repository information after completing the partitioning. I have changed the install type to 'cdrom' before anyone asks! I have removed my %pre and %post sections as these just copy in some config files and do not touch anything other than local paths.

Whenever I try to do anything that requires administrative permissions, including Synaptic, the Update Manager, or installing something on the Software Center, the "Starting Administrative Application" task comes up on the window list, but then the window does not come up and whatever action was supposed to be taken does not happen; no error messages, nothing. Also, whenever I use su or sudo in the command prompt, nothing shows up when I type my password; then when I hit Enter, it gives me an authentication error.
EDIT: It seems that the "Add/Remove Applications" program as well as the Software center do not have this problem. Synaptic and the Updates Manager, however, still do not work.

I'm dual booting XP and UNR and I want to give users access to the windows file-systems but not to admin of Ubuntu.
At present I have given them a Desktop user account but that doesn't allow access to the XP file-systems. The only way I can see to enable that is to go to Advanced User Setting and allow them to Administer the System - which I don't want to do.

After a power cut I needed to restart my Smoothwall 3 box. Things are working fine, except I can no longer access the GUI to open ports (https port 441, or http port81) etc. I get a "(111) Connection refused". I would just reinstall, except my kids have opened up a number of ports over the last few months for games but without keeping a record, and would struggle to have to start from scratch again.
How I can solve the "refused connection" issue, or alternatively, do you know which file on the box stores the port config info so I can take a copy of it before reinstalling. I have looked at /var/log/dmesg and notice I get a "segmentation fault" for the line /usr/apache2/sbin/httpd -DSSL and am guessing this is significant to the problem, but I don't really know what it means or how to fix it. I have rebooted several times, over several days.

First off, since this seems like a networking issue I put it here, but if it should be somewhere else, the powers that be should definitely move it over.
I'm using Ubuntu 10.10 on Dell Presario M2000 I have made sure that all updates have been done.
As the subject states, the admin account (mine which I'm posting to the forum with right now) can access the internet and see webpages. The user account on this laptop (my underaged sister who my parents don't want full access to the computer) will not access any webpages, it just continually looks like its loading.
I have made sure the wireless card drivers are installed and activated.
Also, I ran iwconfig and ifconfig and here are their results
p { margin-bottom: 0.08in; } Results of iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
wlan0 IEEE 802.11bg ESSID:"myqwest4137"
[Code]....
These were both run from the user account. At this point it looks like its connecting to the internet through the wireless card as I was also able to run the update manager through the user account and have it download the updates (after putting in my admin password of course).

I cannot access this computer from other computer (while it was possible before). I looked at the interfaces and everything seems fine. The nic itselft seems to work too.

This is the set up I have: PC downstairs by a tv, with 3TB of storage containing my media, connected to the tv too. HTPC upstairs by another tv and connected to it. A few laptops and other desktops around the house which are windows based
I want the downstairs pc to act as a file server and to run my torrent client, it is running Ubuntu desktop version and has xbmc installed too for use with the tv. The upstairs htpc has xbmc live on and will access the media from the file server. What I am looking to do is to be able to log into my ubuntu machine remotely from a laptop running windows so I can manage the files and add torrents for download etc, but for this to be a complete remote session, rather than taking control over what is already being shown on the downstairs pc, like VNC does in windows.
I have two user accounts set up on the main ubuntu machine, the admin account and a media user account which is set to go straight to xbmc after log in. Also how can I make sure that the media drives are automatically mounted to allow access if the admin user is not logged in?

I managed to configure my W890i phone to get access to internet through an ubuntu-based computer. It's very easy to use the phone to give internet access to the computer, but the opposite is quite more tricky. For that I've done the following
----On the phone---
-Set the USB network option to "through computer", so that the phone uses the computer's internet connection and not the opposite.
-Decide and set "Shared Network" parameters: user, pasword and workgroup.
-In "conectivity-> internet connection" set "allow local network" to "yes"
----On Ubuntu 10.04---
-Install samba, samba-client, smbfs, smbclient, firestarter and dhcp3-server
-Configure Samba (System-> Administration-> Shared folders): same workgroup as in the phone, add new user (the phone), passwd this new user. In my case the user was called "w890i" and the password given was the same.
-Once the phone is connected to the computer through USB (then select "phone mode"), a new connection appears in NetworkManager: usb0.The aim is to create a shared network that gives internet access to this device. Edit the IPv4 parameters of this new connection, set them to Manual and give an IP adress (192.168.0.1) and a subnet mask (255.255.255.0); the rest of the fields are left empty.Connect this network.
-Set firestarter to use dhcp3: sudo ln -sf /etc/init.d/dhcp3-server /etc/init.d/dhcpd
-Launch firestarter and follow the wizard. Set "allow internet shared connection", choose the device for the primary internet access, and then the device for the shared network (usb0). Then change the settings for firestarter: activate DHCP for local network, set IP to the one we gave before (192.168.0.1).
-Open dhcp3-server config file sudo gedit /etc/default/dhcp3-server And set INTERFACES="usb0"
-Set the policies of firestarter: in incoming connections, allow connections from the IP adress given to the phone (192.168.0.1). Then add rules for the ports that need to be open for this connection. I opened HTTP, HTTPS, SMB, SMTP, POP3, IMAP, IMAPS, DHCP for all the connections in the local network.
-Apply policies and start the firewall.
------------
After all this, the phone can access the internet through the computer. Two problems appeared:
1. I couldn't get access to https sites, like webmails. The phone gave a "communication error". But then I tried with Opera instead of the browser built in the phone's firmware, and I could finally get to https sites.
2. I couldn't retrieve mail, neither POP nor IMAP nor IMAPS. I thought it was a firmware problem again, and I tried out several mobile phone email clients written in java, but none of them worked.
So this is at the moment the problem. If I connect from the phone to the internet directly through 3G, the email clients work for all my accounts. I don't think it's a firewall problem, because the ports are opened for this connection

I'm running window xp and unbuntu 10.04. I ran into a problem where I reinstalled unbuntu by erasing old one under CD boot. During installation, it asked me to place files and i placed it in /. Now when I log in as single user (only user or other at login screen) and try to change any system files, it said I don't have permission. I can't change anything or access root file. I try chmod function and it said i don't have permission as well.

I have a local computer (local), and remote computer (remote) behind of remote server (server). Also, I have user access to all of these 3 machines. Now, I want mount some directory, located at remote, to my local mount-point via sshfs. How should I setup my local sshfs and what should be done on server to make this mounting?
I'm stuck with ssh tunneling because the default method for tunneling requires root access while WinSCP somehow could do this with only user access (the tunnel server could be configured there in 'tunnel' panel).

Original HOWTO can be found at: [URL]... So the other day I was in IRC and someone had brought up a problem where they created a new Administrative user, but didnt have rights to use sudo. Looked into the problem a little bit to figure out what was wrong, and it turns out that when you create a new user through the user manager (in kubuntu, anyways. Havent tested in Gnome.) the user gets added to the adm group, however, a quick look at the sudoers file shows that its looking for users in the admin group to allow the use of sudo. So, to solve the problem we do the following: If youre on the new admin user (which Im assuming you are) use the following commands:
Code:
su [insert username of old account without brackets]
sudo usermod -G admin [username of new admin account without brackets]
exit
Then simply logout, and then log back in (not always necessary, but the easiest way to flush the permissions.)
Code:
su [insert username of old account without brackets]
Means were going to Switch User to the old admin account
Code:
sudo usermod -G admin [username of new admin account without brackets]
This simply adds the admin group to the secondary group list for the new user
Code:
exit
Pretty self explanatory

Having just successfully installed fallout 3 (yippee), one question arises.
Is it possible to turn off (and eventually back on) all superfluous process during gaming ? As an ex-win xp user, there was an app called "game booster", i think, that did this.
The process i have in mind are things like fancy compiz settings, dockbar X, and any upgrades that might be taking place in the background.
Again, it is important that i can restart these functions after kicking super-mutant ***.
