General :: Minimal Configuration For Vms Host In Old And Slow Configuration?
May 21, 2010
I have a slow machine, mainly a Celeron with 250gb HD.This machine is not being used, so I was planning to install a Linux distro and create a bunch of VMs for development.Which distro should I choose? I plan to use this machine mainly as a small "hypervisor" to other vms.Is it possible? What do you suggest? (Buying another machine is out of question, since I would like to know if it's possible give a purpose like this to the Celeron)
I am having no luck configuring ProFTPd on a Debian Lenny production server we use to host our MySQL databases and a few websites. I had originally set it up so I could login and manage our internal sites, but I have the need to allow a few clients in to access their sites that we host. I am trying to root the users in their site directory, which would be "/sites/www.whatever.com/".
It just hit me while typing this. Is it possible to create a user without a shell to prevent login via SSH and set the home folder to /sites/whatever instead of /home/username? That would allow me to continue operating with my current configuration and root them in their site while preventing SSH logins.
Recently I tried to install Debian 8.3 from *netinst.iso as a VM on VmWare Worksation 12. I try this in my office where there is a windows proxy set, for some security measures. During the installation in order to download updated and install additional packages I need to choose a mirror and then a proxy. I try to set the proxy but all I receive was an error. Decide to continue with the minimal installation and when the system start just to enter the proxy in etc/profile the reboot and I was thinking that everything will work just fine and I will be able to install everything I need. When I try apt-get install I receive a message Ign cdrom:// Debian ... Then to remove that error I edit /etc/apt/source.list but even then nothing happened when I try to use apt-get install. I receive and error message "Unable to locate the package.
I would like to know if there is a way to install Ubuntu 8.04 with a minimal configuration. Just the desktop and the important programs needed to run/update ubuntu. I'm asking this for my current problem found in this thread URL... hasn't been solved yet, and if the said problem doesn't get solved I would have to downgrade to 8.04 for this is the only version of ubuntu that works with the monitor described in the linked thread. Also, I would like to know if there is a way of installing fonts in 8.04 as easy as adding fonts to 10.04?
I am using the Debian stock kernel. I want a minimal kernel that works on my Pentium 4, 1GB DDR RAM machine. What do I have do to get a less resource hungry OS. Is there already a minimal kernel binary available?
What happened to kde-core? I have two choices of bloat, kde-standard or kde-full. I don't want stuff like konqueror or kmail. I don't want Gwenview, Okular, or Ksnapshot. I don't care for all the media players. I don't need Kaddressbook or Korganizer. Is there a way to do a normal, minimalistic install without this stuff or am I screwed? I want to reinstall on my laptop and the boss' laptop and would prefer not to have the extras,
What must be the best configuration of computer for linux? I have 2.67ghz, 1gbram, 160hdd and running linux-ultimate-edition but computer is run very slow.
I want to see what is the configuration of my Wind River Linux (actually I want to see what modules are installed in it when it was built). I can't find the configuration file.
3 packets transmitted, 0 received, 100% packet loss, time 1999ms.Same result when using the standard Debian ntp time servers like "server 0.debian.pool.ntp.org iburst" in /etc/ntp.conf.
I have setup a few machines within my house. The Debian Squeeze machines do not provide a host name in the DHCP client list on my router. Strangely, my Ubuntu, Android, and Blackberry machines do show host names. I have noticed the same behavior when wirelessly tethering my Debian laptop to my Android phone (which also uses DHCP). Is there something I need to enable to have the name show up on the router?
I am experimenting with installing a bare minimum, network capable installation of Debian Squeeze. Right now, I am having trouble getting proper host name resolution. I have provided the output of ping (which is able to resolve names), wget (which is unable to resolve names), and the contents of the files I believe to be relevant to the problem. When I installed Debian, I installed *only* the SSH Server from the list of available configurations. Since then, I have installed mdns4, dnsmasq, mdns-scan, and libnss-mdns to get name resolution to work with no success so far. All packages were installed with no recommends -- aptitude -R package name. What am I missing to get host name resolution working?
I am trying to set up a DMZ host - that is, one multifunctional PC between the WAN and the LAN. I've started with a basic router, and expanding upon that as the need arises. I am currently trying to gain access (from the WAN) to a website hosted on one of the servers in the LAN, but I am having trouble accessing the host from the WAN; I think my iptables configuration may be too restrictive. On the DMZ host, I'm using Debian (Etch). I have setup dhcp3-server, a script to configure iptables and pound (reverse-proxy). The (virtual) machine has 4 network cards: eth0, eth1, eth2, eth3; eth0 is the WAN, eth1 through eth3 serve 3 different virtual LANs.
All machines in the LAN (except one windows 2008 server - I might want to address that problem later) get their IP adresses correctly via dhcp from the DMZ host. All machines on the LAN can access the internet (including the 2008 server if I configure it manually) as they should. If I access http://localhost on the DMZ host, pound reports "The service is not available. Please try again later." - as it should.
I can ping the DMZ host from the WAN on 10.0.0.79 However, if I try to access the DMZ host from the WAN (http://10.0.0.79) I get "Unable to connect" from firefox. I'm sure this is not a pound problem, so I think it's in the iptables, or maybe I should be installing some extra software that I'm unaware of.
Basically I download to main PC and rsync to my pi as the pi has a fraction of the speed for some reason when downloading form a source outside of my network.
The first few files will sync fine. Then I start getting errors like this
Code: Select allrsync: rename "/data/temp/.File.ext.y1716M" -> "File.ext": No such file or directory (2)
The directory on the host has user and group ownership as pi. Rsync has been setup to login without a password.
Using Debian 5.0 Stable, with all current updates, if I type \192.168.0.249 I get samba access and can use all the shared files ok.if I go via the network the computer should be called \squ-eee-zeboxserver but instead comes up as \SQU-EEE-ZEBOXSERsqu-eee-zeboxserver which when clicked gives the attached error.
my server into the public internet and must have my webserver [2.2.9 (Debian)] act secure. But this does not look very easy [I am searching, reading and working on it already the whole day ]. I read the apache docs, but there is a lot of stuff, which is different in Debian [lenny, 5.0.6]. Apache ignores the host-header given by the browser: [URL] are all served, but should be blocked. I new new to apachy, but on my IIS this works as expected. All browsers act equal [so no browser header problem].I configured two VirtualHosts, an excerpt:
The I go to my hosts file on any box, and add hugo's ip-address under the new name x. Then, x is served, although the host-header in apache Every user coming from the internet could make the same!
I've just installed Debian Squeeze from a live CD. When I open a web browser (be it iceweasel or epiphany) and try to go to google.com, it tells me it can't resolve the host name. [Edit: They do, however, allow me to go anywhere on debian.org, minus the search feature] I also get the same error when I try to go to my website running on a local server. However, when I type the server's IP address (192.168.0.10), it goes to the website fine. Basically, any program I run that needs to resolve a host name returns an error, with the exception of the host command:
I've tried changing my DNS server IP from 192.168.0.1 (my router, configured to provide DNS) to 192.168.1.254 (my internet modem, also configured to provide DNS). That didn't help any. Then I changed my DNS server IP to the same one used by the modem, and now everything works.
I've tried googling my way out of the issue, and I've found where someone had the same issue as I've got and fixed it by adding "blacklist ipv6" to their /etc/modprobe.d/blacklist.conf file, but that didn't work for me.
So, recap: Why does resolving domain names fail for certain applications (except the "host" program) when the DNS server IP is that of my router or modem (which works fine for all of my other computers), but suddenly works when I point the computer straight to my ISP's DNS servers, and how can I permanently fix the problem?
I am trying to enable DHCP so that it will give out IP's to some XP boxes when they boot. I have had success doing it dynamically, but not statically using the host declaration. host xpTest { hardware ethernet 00:50:56:2A:3B:00; fixed-address 192.168.100.2; } My question is, what should the subnet declaration be if I only want to hand out static IP's like this? Also, the host is the same name that is specified in /etc/hosts correct?
How to give mulitple virtual host in apache. I want to access all my sites with ip 192.168.1.125
For ex :if i want to access dpm.net it should have the ip 192.168.1.230 with port 80 & for persur.net it should have the same ip 192.168.1.230 with port 80
After restarting the apache servers.I am unable to run both the applications in a single time.
For that i gave Include /etc/apache2/sites-enabled/[^.#]* in apache2.conf. But still its not working.
I'm using Debian 5 with Exim 4 on my VPS. My purpose is to make mailboxes for each virtual host on my server. What do I have: 1. Exim is set correctly - receiving mail from [URL]... is successfull. 2. Mail for [URL]... is delivered, and the mail for [URL]... too. But [URL]... is the site written to /etc/hosts (it's localhost), and [URL]... is virtual host. But mail from both boxes writes to /var/mail/mail. Now what do I need: 1. Make mail for [URL]... store in [URL].... and mail for [URL].. store in www/Maildir. 2. Make mailboxes like [URL].... to receive mail by Thunderbird. 3. Set passwords for [URL]... and [URL]... (I don't want to enter my system user/root passwords).
I have a strange iptables issues. I have just built a new Debian install and starting adding some real basic rules (see below) the problem seems to be that the localhost itself can't get any returning traffic. That is, it seems to be allowed outgoing traffic but not the connected, returning traffic. Ordinarily allowing Established Connections would resolve this, see the rule below, but it hasn't. Why this doesn't work. Removing the last DROP in the INPUT chains obviously makes the traffic work!
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A INPUT -j ACCEPT -p tcp --dport 22 iptables -A INPUT -j ACCEPT -s x.x.x.x iptables -A INPUT -j ACCEPT -s x.x.x.x iptables -A INPUT -j ACCEPT -s x.x.x.x -p tcp --dport 80 iptables -A INPUT -j ACCEPT -s x.x.x.x -p tcp --dport 8080 iptables -I INPUT 1 -i lo -j ACCEPT iptables -A INPUT -j DROP
I have a problem with the Fedora 12 Network Manager - OpenVPN configuration. If I use the same configuration and manually start openvpn (as client) I get connected to the OpenVPN server and I can ping the network that I am accessing. With Network Manager - I get connected but when I try to ping is giving me "Destination host unreachable". The routing table looks similar except that when connecting with network manager is giving me on more route in table

What I do wrong in Network Manager? If I try to delete the route with xxx.xxx.xxx.xxx is disconnecting the vpn connection.
I installed debian etch, it runs and does connect to the internet fine through a linksys router...the linksys router is connected to my cable modem...now..
I just registered for a domain name (ex. mydomainname.org) with Verio....this is where I am stuck.
I installed apache 2, a web server, file server (all seem to work) I need to know what files I need to configure to have my machine actually BE that domain name.
Ex. my linksys DHCP IP addresses, the linksys gets an IP from the cable modem...my yquestion is ONCE I register a domain name with verio...how do I configure my end so it "knows" I am that respective domain name...I think I need to configure the following, but knot sure how to do it: resolv.conf, hosts, and interface?
I have an OpenSuse 11.2 system that is running 2 BBS systems independently, both of which are capable of receiving smtp mail on prot 25. What I would like to do is set up Postfix on the OpenSuse OS to receive all mail for both those domains and then send the relevant mail to the correct BBS. I would therefore have Postfix listening on Port 25 External and the 2 BBS applications listening on different ports on the localhost address. At least that is the plan.
how to do this. I want to do it and still make sure Postfix is secure and not accidentally open up any nasty relay holes etc etc.
I have installed jessie on a couple of machines. One is configured as the NFS filesystem exporter and NIS server. The other one, I am trying to configure as NFS and NIS client. NFS does not seem too much of a problem, I can mount the exported filesystem to a directory in the client and unmount it, but when I install NIS the system becomes very slow. Any command preceded by "sudo" takes a very long time (a few minutes) to complete. Then, upon rebooting the system, it reports many services failed to start (login, accounts, modem manager, avahi, network manager, exim). When if finally completes, I get a terminal login, instead the graphic login window.
i use a telekom s100 set-top-box, which originally had a prism54 wlan-card. but wlan was very slow. but the driver was working well and it did not seem to be a configuration issue, so i assumed that its that card which is so slow. following i purchased a atheros based wlan-card which is working perfectly well with the ath5k driver of my linux kernel (2.6.26-1-686). but the connection is pretty bad anyway. i get max 300kb/s from pc to pc. as its the same with 3 different cards i tested in the s100 i assume it is a configuration issue? or might there be chipset or mini-pci-slot limitation?
when i check the connection with iwconfig the bitrate is somewhere between 1-54mb/s, rising to 54mb/s and then falls back to 1mb/s, rising to 54mb/s again, falling down, its an infinite loop. im using wpa_supplicant for the connection, but i don't think thats the malefactor. well, you never know .. i tried to set the bitrate with iwconfig wlan0 rate 54M but that ended in a disconnection ...
I'm running testing and over the last week or two my system is getting slow. Any disk access slows everything to a crawl. Even the cli can take several seconds to display characters as I type them.
I have 64bit debian 6 squeeze installed on my 64bit pc. I have an NVIDIA gpu which I have installed the drivers for and they work just fine. I also have a 32 bit chroot located at /32 which was created using debootstrap. The NVIDIA 64bit driver gives the option to install compatability driver libraries into the 32bit chroot. Whenever I run any application that uses opengl rendering within the chroot, they segfault. When I uninstalled and reinstalled the NVIDIA driver without installing the libraries to the chroot, and instead replaced them with mesa gl libraries, the programs complain about framebuffer missing. They do not segfault, and some programs that can use sdl instead will work fine. I have xhost + set to allow any programs in the chroot to use the host's xorg. I have the host's proc mounted to the chroot proc directory, and i also have dev mount --bind 'ed to the chroot.
Debian Testing host, Winduhs XP guest. Winduhs is not allowed to directly access The Internets, and I am not setting up bridging as that makes it possible for the guest to mount layer 2 attacks on the LAN. I need for the guest to tunnel through the host without being able to see anything on the host, so it can then get access to The Internets, while being protected by iptables (Shorewall).
Used to be with VMware I had host-only set and the guest in a different class c (192.168.2.1) from the host (192.168.1.1) I turned on ipforwarding, set Shorewall rules, and it all worked. Now I have everything set with VirtualBox, and it does not work. Guest can ping its interface but not host. Host can ping vboxnet0. Host is supposed to masquerade guest's 192.168.2.1 through to the default out at 192.168.1.1, but it's not. I think a clue is in routing, but I don't know what's wrong.
Intel Core i7-5500U with Intel HD Graphics.So I updated to the backports kernel and backports intel xorg drivers and I have the weirdest thing.Everything is stuttery even cinnamon desktop effects are no longer smooth. If I boot back to 3.16, everything is butter (except the screen corruption). Even my favorite wine game dropped 25% in fps.
I remember that on windows, if the cpu is too slow (pstate_min_speed), graphics is also stuttery. However, increasing /sys/devices/system/cpu /intel_ pstate/min_perf_pct even to 100% didn't do the trick. I suspect, that this measure is causing it: URL....
how to increase the performance again? I just found out, after running glxgears (with about 40 fps), that xrandr shows an available framerate of 40fps
xrandr Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767 eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 293mm x 165mm 1920x1080 60.00*+ 59.93 40.00
I guess that's what makes it feel slow. Do you know how to get that back up to 60 (fixed)? It seems like the screen refresh rate set in xrandr has no effect on the problem. When I boot, glxgears runs with 60 fps and everything is fine. After a while, it drops to 40 and the whole desktop keeps stuttering. if I change the resolution with xrandr and then change it back, it goes to 60 again for a while
