Am using 10.04 and quite happy with the way it is working. my nephew and my mother have also switched to ubuntu.
To save on internet usage and load on the ubuntu servers, can i download upgrade files in one computer and then upgrade all systems?
On other editions of ubuntu server I had no problem saving multiple users and passwords with htdigest but now it seems it is only possible to save one user and password.
Code:
sudo htdigest -c /etc/apache2/passwords directory user
When I add a second username and password for the same directory it overwrites the first.

View 1 Replies View RelatedI've run into a problem gathering usage for my xen virtual systems. With my old model I used to gather all network usage via my cisco devices using the the counters for each port. Each system had it's own port on the switch, and I tracked network usage accordingly. Now that I'm using xen for virtual systems, and multiple vm's share the same switch port, i'm not exactly sure what my best option is for tracking usage.
I thought I may be able to setup vlans on the switch, and bind each vm to a different vlan using vconfig... but it seems like there has to be a better solution than that.
Ever need to provide access to multiple PC's and did not have a router only a hub. Maybe this isn't original thinking, but then again maybe you didn't think of doing it this way (which i am sure there are many ways to do it) So I have 2 Ubuntu Servers, 1 Windows Box and a Hub - All 3 with internet access off of single ip and single Ethernet port.
While searching for a backup method today I came across Clonezilla. I was wondering if this was the right thing for me and since I needed to backup my roommates PC for a reformat and install of Windows I decided I would give it a try, but only if it would work. I didn't want the hassle of going into the main part of the house and finding out what cord was what as there is a cable modem connected into a switch (4 static IP's with internet) and one port of the switch hooked to a router) Anyways, didn't work he was on the router I was on the switch)
But this got me thinking. When I setup my server to do this, during one of the setup scripts it said it was setting up Internet access for client machines and that it was assigning them IP addresses threw a DHCP server that it had installed.
So, I dug up the hub connected the internet cable to hub up link and Server 1 on port 1 Server 2 on port 2 and Windows on port 3 The main server gets the internet provided IP address and routes it to the hub via a virtual interface. Server 2 is configured for DHCP and the windows box, It was set to get info automatically but it didn't fill the DNS info so I had to manually do that (just a heads up) I decided to use OpenDNS Servers (208.67.222.222 & 208.67.220.220) but im sure putting in the gateway IP address would have worked too.
So, by now if you need this I am sure you are excited and want to get to it. Like i said there are probably other ways of doing it, ways that don't involve you installing clonezilla and DRBL, maybe even just DRBL is needed, maybe one of them installed whats needed as a dependency- all I know is it works, if you know - elaborate so people know, but hey- this way not only do you have internet access on all PC's you can deploy custom images to them as well.
I just installed ubuntu 10.04 x64. I have installed it and set it up the way I like on my server, however I now have 3 terminals and a laptop to set it up on the exact same way. As a result Id like some advice on what can and cant be done and how. Preferably I am looking to use programs with GUIs. Thing the style of ubuntu one, software manager etc, not really too into the command line, or conf editing unless there is no other option.
1. I installed all the software from software centre I like. Now I need the same software on the other computers. I know mint has mintbackup where it just exports and imports a list if installed software. I am looking for an ubuntu equivalent.
2. Firefox and Thunderbird add-ons. I install like 20 firefox and thunderbird add ons. sometimes I can't even keep track of them. There must be a way to sync them so that each computer I install ubuntu on I can simply import the list of mozilla add ons and have it auto download them.
3. Mail Contacts and Calender Syncing. I need to sync between my 3 ubuntu machines and my windows mobile 6.5 device for calender, email/phone/name contact lists. Email is taken care of by imap, but lightnings calender isnt and neither are the contacts. If I input a contact on my phone I want it to sync to the other computers I use.
4. Ubuntu one. I have /storage/workfolder in my root directory on my personal server. I want to be able to work on documents at work on my laptop and sync them so that when I get home, they are synced on the server without causing overwrite changes etc.
5. Desktop settings, icon themes, preferences from ubuntu tweak etc. I know this one is a bit more of a long shot, but it takes 20 minutes each computer, to set up the little maximize minimize buttons on the other side, set up cairo dock the way I like, install the icon theme and backgrounds I like. isnt there a way to back this up so it doesnt have to be done each time or so I can make my other computers the same?
run a cron job to download my email logs to my laptop. But the question is HOW? Im not sure how to write the php script for the cron job. the file is on "computer A" and the file is setup to chmod I just need to know how to write the php to "access" the other computer and then download the file to a certain file on my laptop.

View 6 Replies View RelatedI have a network of 20 machines, all running Ubuntu 10.04.
Each machine has about 200[GB] of data that I'd like to share with all other 19 machines for READ ONLY PURPOSES. The reading should be done at the FASTEST POSSIBLE WAY.
A friend told me to look into setting up HTTP / FTP. Is it indeed the optimal way to share data between the machines (better than NFS)? if so, how do I go about it?
UPDATE: Just to clarify, all I want is to be able (from within machine X) to access one of machine Ys files and LOAD IT INTO MEMORY. all of the files are of uniform size (500 [KB]). Which method is fastest (SAMBA / NFS / HTTP / FTP)?
Im new to the forum and fairly new to Linux as well. my apologies if this is posted in the wrong section. My problem is How can you search for a file in multiple machines (like a server farm) ? For example i log onto machine num1 and want to search for a file named "xxx.yyy" which may be in one of 4 machnies. What i do right now is manually log into each machine and run the find command. However i have heard that it is possible to do it via a couple of simple commands. I have looked into pssh and cssh as well as ssh tunneling (along with public key authentication to stop the machines requesting a password every time i log in) and unfortunately i was unable to find an answer.
View 4 Replies View RelatedI have a home network with 6+ x86_64 machines, all with similar setups. In the past (FC10 and before), I've had common package repositories (e.g /var/cache/yum/fedora/packages) shared via NFS with all the machines (and with keepcache=1 in /etc/yum.conf). That way, a given RPM only got downloaded once; the other machines would then pull it from my local package repository. And I don't mind the disk usage of keeping one copy of all my old RPMS around.
It seems that while DRPMS is great for a single machine, it doesn't make sense in my case. If I have to download the DRPM 6 times (and take the time/CPU hit to recreate the RPM 6 times), I might as well have downloaded the RPM once and been done with it. Is there a not-too-convoluted method to keep a common package repository across multiple machines even with DRPMS? Or, better, to have that first downloading machine pull a DRPM, generate the RPM, then save the RPM in the local shared repository?

ok I am using Debian 4 bigmem and I set up static ip for my box. This is for a class and we will be moving the hard drives around the lab to different computers. My question is what do I configure to get Debian to be ok with my using different nics at different times.
My first time I used it, I had eth0, but now I'm on a different computer (same type of hardware on all systems) but my nic is now eth1... And I had to set up static again for that nic. How can I have it just maintain a static ip for whatever nic/mac address on the computer that my hard drive happens to be put on?

from internet only one host is allowed SSH. This machine has public IP and is also connected to LAN on the IP 192.168.1.50. Tunnel is not allowed on our network.So now I am came across a solution as explained on this link. I am not clear with on which machine .ssh/config file I add following
Code:
Host securehost.example.com ProxyCommand ssh user1@insidemachine.com nc %h %p Should above be done on gateway where public IP and ssh is allowed or client on internet who has to login. Do I need to create separate accounts on the gateway also so that the users who can SSH to gateway then are forwarded to inside machines? Or one account on gateway is sufficient for different people logging in via internet to my gateway and then forwarded to internal machine?
Then do I need to create an account user1 on the gateway also?
1) What is the correct syntax for ProxyCommand on gateway's .ssh/config should I use
Code:
ProxyCommand ssh user1@inside.machine nc %h %p
or I should use
Code:
ProxyCommand ssh user1@gateway.com in nc %h %p
2) Should I create new user accounts on gateway also which exist on internal machine?
I've been having some problems trying to get a new netbook working with China Telecom's 3G service (works wonderfully in Windows, but still trying to figure Ubuntu out), so until I figure out the problem with this Huawei modem, I've written a quick python script to handle updates/installations on the Ubuntu side. (Synaptic does fine on generating download scripts for packages, but it needs an option to handle updates as well)
If anyone else has a use for this, you're welcome to use it. Please let me know what needs to be changed to make it work on your box.
