  • mount remotely mybook live network drive

    - by bob
    I have a mybook live western digital 1TB hard disk connected to fritzbox 7270 router in office. When I am in the office, I can mount this drive to ubuntu since I have added to the etc/fstab file: //192.168.178.30/user /home/user/DISK cifs auto,iocharset=utf8,user=user%password 0 0 Is there a similar, easy & safe way, to do the same when I am out of the office using the static IP of the fritzbox router? I have already added tcp port forwarding in the router for ports 8080 (to 80 of the disk) and 8443 (to 443 of the disk). Thank you in advance

  • How to mount private network shares on login?

    - by bainorama
    I've read all the existing entries I could find on using pam_mount but none of them seem to work for me. I'm trying to automatically mount shares on my local NAS at user login time. The usernames and passwords on my NAS shares match my local user name and password, but there is no LDAP/AD server. My pam_mount.conf has the following: <volume fstype="cifs" server="bain-brain" path="movies" user="*" sgrp="bains" mountpoint="/home/%(USER)/movies" options="user=%(USER),dir_mode=0700,file_mode=700,nosuid,nodev" /> When I login, I see the following in /var/log/auth.log: Oct 13 10:21:26 bad-lattitude lightdm: pam_mount(misc.c:380): 29 20 0:20 / /home/alastairb/movies rw,nosuid,nodev,relatime - cifs //bain-brain/movies rw,sec=ntlm,unc=\\bain-brain\movies,username=alastairb,uid=1000,forceuid,gid=1000,forcegid,addr=10.1.1.12,file_mode=01274,dir_mode=0700,nounix,serverino,rsize=61440,wsize=65536,actimeo=1 The folder /home/alastairb/movies is present but empty (can't see the files which are on the NAS in the respective share folder). In Nautilus, the share is shown in the sidebar under "Computer", and clicking on this takes me to the correct folder, but again, its empty. Any ideas as to what I'm doing wrong?

  • Communicating with all network computers regardless of IP address

    - by Stephen Jennings
    I'm interested in finding a way to enumerate all accessible devices on the local network, regardless of their IP address. For example, in a 192.168.1.X network, if there is a computer with a 10.0.0.X IP address plugged into the network, I want to be able to detect that rogue computer and preferrably communicate with it as well. Both computers will be running this custom software. I realize that's a vague description, and a full solution to the problem would be lengthy, so I'm really looking for help finding the right direction to go in ("Look into using class XYZ and ABC in this manner") rather than a full implementation. The reason I want this is that our company ships imaged computers to thousands of customers, each of which have different network settings (most use the same IP scheme, but a large percentage do not, and most do not have DHCP enabled on their networks). Once the hardware arrives, we have a hard time getting it up on the network, especially if the IP scheme doesn't match, since there is no one technically oriented on-site. Ideally, I want to design some kind of console to be used from their main workstation which looks out on the network, finds all computers running our software, displays their current IP address, and allows you to change the IP. I know it's possible to do this because we sell a couple pieces of custom hardware which have exactly this capability (plug the hardware in anywhere and view it from another computer regardless of IP), but I'm hoping it's possible to do in .NET 2.0, but I'm open to using .NET 3.5 or P/Invoke if I have to.

  • XP Missing AD in secuirity location

    - by Rodent43
    I have a few Window XP clients that are part of a domain, when trying to set the permissions on the security tab and pressing location to search the AD for users it only presents the local machine... So I follow this path Right click folder Properties Security Add in the locations field where I would normally see the windows domain, I am only seeing the local machine name??? So only users that have a local account can be added to the folders permissions... Any tips would be appreciated

  • immplementing security with session variables, how it is insecure

    - by haansi
    Hello, I am doing web based projects in dotnet. Currently I am implementing security using session variables. I keep current user id and user type in session and authenticate user from these session variables (say Session["UserId"],Session["UserName"] and Session["UserType"]) I do authentications. Please guide me how it is insecure ? I heard such security can be broken and applications can be hacked very easily, like it is possible to get session id and directly connect to that session id etc. Please guide me on this thanks

  • Unable to access internet if wireless enabled

    - by balki
    The following is my route output. eth0 is my wired network and eth1 is my wireless network. Only wired one has access to internet. If I enable wireless, I am not able to access internet, it tries to access via eth1 and I get 404 page of the wireless router. Why does eth1 have higher preference though default is eth0 (link)? [balakrishnan@mylap ~]$ route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 10.26.0.1 0.0.0.0 UG 0 0 0 eth0 10.26.0.0 * 255.255.192.0 U 1 0 0 eth0 link-local * 255.255.0.0 U 1000 0 0 eth0 192.168.1.0 * 255.255.255.0 U 9 0 0 eth1

  • Is this iptables NAT exploitable from the external side?

    - by Karma Fusebox
    Could you please have a short look on this simple iptables/NAT-Setup, I believe it has a fairly serious security issue (due to being too simple). On this network there is one internet-connected machine (running Debian Squeeze/2.6.32-5 with iptables 1.4.8) acting as NAT/Gateway for the handful of clients in 192.168/24. The machine has two NICs: eth0: internet-faced eth1: LAN-faced, 192.168.0.1, the default GW for 192.168/24 Routing table is two-NICs-default without manual changes: Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 (externalNet) 0.0.0.0 255.255.252.0 U 0 0 0 eth0 0.0.0.0 (externalGW) 0.0.0.0 UG 0 0 0 eth0 The NAT is then enabled only and merely by these actions, there are no more iptables rules: echo 1 > /proc/sys/net/ipv4/ip_forward /sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE # (all iptables policies are ACCEPT) This does the job, but I miss several things here which I believe could be a security issue: there is no restriction about allowed source interfaces or source networks at all there is no firewalling part such as: (set policies to DROP) /sbin/iptables -A FORWARD -i eth0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT /sbin/iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT And thus, the questions of my sleepless nights are: Is this NAT-service available to anyone in the world who sets this machine as his default gateway? I'd say yes it is, because there is nothing indicating that an incoming external connection (via eth0) should be handled any different than an incoming internal connection (via eth1) as long as the output-interface is eth0 - and routing-wise that holds true for both external und internal clients that want to access the internet. So if I am right, anyone could use this machine as open proxy by having his packets NATted here. So please tell me if that's right or why it is not. As a "hotfix" I have added a "-s 192.168.0.0/24" option to the NAT-starting command. I would like to know if not using this option was indeed a security issue or just irrelevant thanks to some mechanism I am not aware of. As the policies are all ACCEPT, there is currently no restriction on forwarding eth1 to eth0 (internal to external). But what are the effective implications of currently NOT having the restriction that only RELATED and ESTABLISHED states are forwarded from eth0 to eth1 (external to internal)? In other words, should I rather change the policies to DROP and apply the two "firewalling" rules I mentioned above or is the lack of them not affecting security? Thanks for clarification!

  • Sharepoint page level security

    - by ifunky
    Hi, Another SharePoint question from myself! I've created a subsite and from within Sharepoint designer I've created a new aspx page, all nice and simple so far. I can't seem to find where I can change the security on this new page, only site admins can view the page and everyone else gets access denied. It doesn't seem to inherit the permissions from the parent and I can't see where to change the security settings! Please help, I'm sure it's something simple! Thanks Dan

  • Security review of an authenticated Diffie Hellman variant

    - by mtraut
    EDIT I'm still hoping for some advice on this, i tried to clarify my intentions... When i came upon device pairing in my mobile communication framework i studied a lot of papers on this topic and and also got some input from previous questions here. But, i didn't find a ready to implement protocol solution - so i invented a derivate and as i'm no crypto geek i'm not sure about the security caveats of the final solution: The main questions are Is SHA256 sufficient as a commit function? Is the addition of the shared secret as an authentication info in the commit string safe? What is the overall security of the 1024 bit group DH I assume at most 2^-24 bit probability of succesful MITM attack (because of 24 bit challenge). Is this plausible? What may be the most promising attack (besides ripping the device out off my numb, cold hands) This is the algorithm sketch For first time pairing, a solution proposed in "Key agreement in peer-to-peer wireless networks" (DH-SC) is implemented. I based it on a commitment derived from: A fix "UUID" for the communicating entity/role (128 bit, sent at protocol start, before commitment) The public DH key (192 bit private key, based on the 1024 bit Oakley group) A 24 bit random challenge Commit is computed using SHA256 c = sha256( UUID || DH pub || Chall) Both parties exchange this commitment, open and transfer the plain content of the above values. The 24 bit random is displayed to the user for manual authentication DH session key (128 bytes, see above) is computed When the user opts for persistent pairing, the session key is stored with the remote UUID as a shared secret Next time devices connect, commit is computed by additionally hashing the previous DH session key before the random challenge. For sure it is not transfered when opening. c = sha256( UUID || DH pub || DH sess || Chall) Now the user is not bothered authenticating when the local party can derive the same commitment using his own, stored previous DH session key. After succesful connection the new DH session key becomes the new shared secret. As this does not exactly fit the protocols i found so far (and as such their security proofs), i'd be very interested to get an opinion from some more crypto enabled guys here. BTW. i did read about the "EKE" protocol, but i'm not sure what the extra security level is.

  • Network programming under windows: is WSA functions can be more complete than pSock functions [on hold]

    - by Kane
    I plan to make a set of classic socket functions to simplify their usages. Since i work under windows and linux indifferently i usually make it portable (it's not my first version of this set of functions), but i want to do something different this time and dedicate one version to windows, and one other to linux. With that i wonder for the windows version, if the WSA* functions can have any interest using them instead of the psock ones. I have found nothing about a comparison between them, so if any of you have any idea, suggestion, link or benchmark ?

    This question already has an answer here: Correct way of mounting a Windows share 1 answer I hope someone can help me.. I'm trying to connect with my university remote filestore, but I can't make it work.. Here is explained what to do on Windows or Mac, and here I found a guide about how to do it with ubuntu, but it's not working to me (at the end of all the steps, I can't access to the mounted folder). I can access to the storage through Konqueror (I'm using KDE), but I would like to access to it also without it. Any suggestion?

  • Question Virtual Network and NAT set-up

    - by Jay
    Hi Guys! I need some help. I'm completely new to Linux. I'm trying to set up the following scenario: +-----+eth0 +-----+ +---+ | VM2 |-----------| VM1 |---------------| H | +-----+ eth1 +-----+eth0 (NAT) +---+ VM2 - Virtual machine from Virtual Box, using Ubuntu VM1 - Virtual machine from Virtual Box, using Ubuntu: I want this to act as a NAT. H - Host, my Windows Vista The dots were just added since after saving the spaces disappear. So if I ping H from VM2, H would receive a different IP address from VM2. Could you give me a step by step on this? All machines are of course 32 bit. Thanks. Would appreciate the help so much.

  • How do I update Safari on Windows?

    - by James A. Rosen
    I'd like to update Safari to 4.0.5 for security reasons, but I can't figure out how to run the Apple updater manually. On Mac there's usually a "Check for Updates" menu item, but I don't see one on the Windows version. I tried downloading the latest version from http://www.apple.com/safari/download/, but Windows won't let me open the file, saying it is a security risk.

  • Network Computers Not Showing up

    - by Muhnamana
    Alright, 3 machines running, two using Ubuntu 11.10 and one on Mac OS X. On the two Ubuntu machines, both have samba installed and configured on the same workgroup, "HOME". On machine 1, I can see all networked machines. On machine 2, I can only see the Mac OS X machine. It doesn't show the other Ubuntu machine. What am I missing on machine 2 to see all networked computers? Any suggestions are welcome. I'm pretty much stumped.

  • Issues running alongside windows and connecting to wireless network

    - by user292247
    Okay so I'm trying to get started with ubuntu but I'm encountering a couple problems: When I boot up the CD and try to install, it does not recognize that I have windows 7 installed and just sees it as unallocated space so the only way I've been able to install it is by wiping the drive which was fine, but it'd be nice to be able to boot either. And secondly, I cannot figure out how to get wireless working. When I try to connect on the initial installation process it tells me to connect to my adapter and just asks for a password. I suspect it could be a driver issue but I wouldn't know where to find it. I have an AR9485 atheros adapter and am attempting to run ubuntu 14.04. Thanks

  • PCs with Wired Connection Keep Losing Internet Connectivity

    - by user717452
    I have a U-verse ATT DSL Internet at our church building. Recently, any computer that is plugged into the network via Ethernet keeps losing its internet connectivity. The setup is from the Modem to a Netgear Wireless Router, and from the router to 3 different computers. None of the laptops that use Wifi ever lose internet, just the wired ones, and I end up having to do ipconfig /release and /renew every day to get it back. One computer has Windows 7 and one has Windows XP. Any ideas as to what is going on with our network?

  • Performance & Security Factors of Symbolic Links

    - by Stoosh
    I am thinking about rolling out a very stripped down version of release management for some PHP apps I have running. Essentially the plan is to store each release in /home/release/1.x etc (exported from a tag in SVN) and then do a symlink to /live_folder and change the document root in the apache config. I don't have a problem with setting all this up (I've actually got it working at the moment), however I'm a developer with just basic knowledge of the server admin side of things. Is there anything I need to be aware of from a security or performance perspective when using this method of release management? Thanks

  • D-link Local wireless

    - by Filippo
    I created a wireless network inside a D-Link DIR-301 connected to a Mac, What I want is that every device to connect to this network if the browser automatically opens instead of the default homepage, it redirects to my website already set in the localhost of the machine which also has the router attached. I'd also like to see that instead of the IP to connect to the site, there will be a "fake" link. What do you advise me? how can I proceed? I state that I am a bit novice in this field, being more a web programmer.

  • Windows Security popup window pops up each time any connection is made

    - by MC Emperor
    I have a problem with the Windows Security popup below. It pops up every time the system tries to make connection with any internet source. It's very annoying, and I don't know how to resolve the problem. (The popup window below is in Dutch, but says something like Connect to somedomain.com. Then it expects you to give your credentials.) I am running on a Windows 7 x64 OS. Now how do I solve this problem? Is it a Windows Firewall problem?
