  • How to set up an rsync backup to Ubuntu securely?

    - by ws_e_c421
    I have been following various other tutorials and blog posts on setting up a Ubuntu machine as a backup "server" (I'll call it a server, but it's just running Ubuntu desktop) that I push new files to with rsync. Right now, I am able to connect to the server from my laptop using rsync and ssh with an RSA key that I created and no password prompt when my laptop is connected to my home router that the server is also connected to. I would like to be able to send files from my laptop when I am away from home. Some of the tutorials I have looked at had some brief suggestions about security, but they didn't focus on them. What do I need to do to let my laptop with send files to the server without making it too easy for someone else to hack into the server? Here is what I have done so far: Ran ssh-keygen and ssh-copy-id to create a key pair for my laptop and server. Created a script on the server to write its public ip address to a file, encrypt the file, and upload to an ftp server I have access to (I know I could sign up for a free dynamic DNS account for this part, but since I have the ftp account and don't really need to make the ip publicly accessible I thought this might be better). Here are the things I have seen suggested: Port forwarding: I know I need to assign the server a fixed ip address on the router and then tell the router to forward a port or ports to it. Should I just use port 22 or choose a random port and use that? Turn on the firewall (ufw). Will this do anything, or will my router already block everything except the port I want? Run fail2ban. Are all of those things worth doing? Should I do anything else? Could I set up the server to allow connections with the RSA key only (and not with a password), or will fail2ban provide enough protection against malicious connection attempts? Is it possible to limit the kinds of connections the server allows (e.g. only ssh)? I hope this isn't too many questions. I am pretty new to Ubuntu (but use the shell and bash scripts on OSX). I don't need to have the absolute most secure set up. I'd like something that is reasonably secure without being so complicated that it could easily break in a way that would be hard for me to fix.

    - by user289168
    I have recently changed my operating system from windows 8 to ubuntu 14.04, when trying to connect to the network via wifi the system just keeps asking for my password over and over without connecting. The connectivity through an Ethernet cable is perfectly fine however and my wifi worked fine through windows 8, I have very little ubuntu knowledge so i apologise if the right information is not shown in this question. Just wondering if there was any known problems or if anyone has seen this before? Thanks in advance for any help, Tom

  • Does Google penalize pseudo-duplicate pages for different locations?

    - by mikewowb
    My compony's site's home page was not specificly optimized to any location. Now, I am planning to optimize it to Boston, and create ten or so other landing pages for other locations we serve. If we made these new pages by copying the original Boston one and changing the location's name (s/Boston/Montreal/), would Google consider them as duplicate pages and penalize us? What is the best practice for this?

  • Managing Printers with Group Policy, PowerShell, and Print Management

    Just because it is possible to do many configuration jobs 'click by bleeding click', doesn't mean that it is a good idea. It is better to step back, plan, and use the advanced resources provided for managing large network. Printer configuration is the perfect illustration of this, and Joseph demonstrates how the use of Group Policy, PowerShell, and Print Management can turn a time-consuming chore into a pleasure.

  • IPC in C under linux

    - by poly
    I'm building a messaging solution with the followingsetup: all the messages are saved on a DB, two or more reader processes will read from this DB and send data to other process(es) which will send it over the network. My approach is depicted below, The following have 4 sender process with 4 fifos, and 2 readers with 2 fifos reader0 ? read data from DB reader1 ? read data from DB sending part network_handler0 ? network_handler_fifo0 ? reader0 network_handler1 ? network_handler_fifo1 ? reader1 network_handler2 ? network_handler_fifo2 ? reader0 network_handler3 ? network_handler_fifo3 ? reader1 receiving part network_handler0 ? reader_fifo0 ? reader0 ? write to DB network_handler1 ? reader_fifo1 ? reader1 ? write to DB network_handler2 ? reader_fifo0 ? reader0 ? write to DB network_handler3 ? reader_fifo1 ? reader1 ? write to DB I have few problem with this setup, and please note that the number of processes could be more than that based on the environment, so I could make it 20 readers and 10 network_handlers or it it could as shown above. The size of the buffer is 64K and the message size is 200k, is this small enough to make the write/read to/from fifo atomic? How can make the processes aware of each other, so for example, reader 0 writes to network_handler_fifo0 and network_handler_fifo2, how can I make it start writing on other fifo if the current ones are full or their network_handlers are dea d I thought about making the reader process writing more general in writing, so for example it writes to all network fifos using lock mechanism and stop writing on the one that its process dead, I didn't use it as lock mechanism could slow thing down. BTW, each network_handler is an SCTP association, so network_handler0 is association 0, network_handler1 is association 1 and so on. Any idea is appreciated. I mean even if I have to change the setup above.

  • Why does the file lens not search mounted samba shares?

    - by Kaput1982
    I've got several samba shares mounted in my home directory (mounted with the "mount.cifs" command). I can browse the shares just fine. From Nautilus I can search them just fine. My question is why doesn't the dash file lens search the mounts as well? I've also noticed files I open from the shares do not show up as recently used (again in the file lens). I've Googled around and I've been unable to come up with any thing.

I've tried loading earlier kernels [3.2.0 ] but that hasn't helped. I've tried playing with alsamixer, unmuting and raising volume, doesn't work I've tried playing with pauvcontrol, doesnt work. Althought, strangely, when i play a song, under output i can see a bar moving implying that something is working, just the sound isn't getting through my speakers. Thus it might be a hardware problem. I've tried unistalling and reinstalling pulsaudio annd alsamixer, doesn't work [maybe made it worse...]. I've heard reverting back to kernel 3.0... works, but i'm reluctant to try that[i dont know much about kernels]. Thank you. Please tell me what other information you need. EDIT: My audio has started working again after another reboot. However this time im not connected to my external audio on startup. I will see if this is the issue next time i'm at home Edit: Connecting to external audio is not the problem.

    I have Broadcom bcm43224 wifi card with proprietary broadcom sta driver. At home wifi connection works well, but in the office when I ping some resource there is a lot of loss packets and I cant browse websites. I have tried another way to check internet connection - download file with wget. wget google.com - very slow speed wget -4 google.com - normal speed So, it seems that the problem is with the ipv6 configuration at the office, can I force my wifi connection to use only ipv4 and completely ignore ipv6 ?.
