  • Should the virtualization host be allowed to run any service?

    - by Giordano
    I recently setup a virtualization server for the small company I'm running. This server runs few virtual machines that are used for development, testing, etc... My business partner works from a remote location, thus I also installed a vpn server on the virtualization host to make it possible for him to safely reach the company services. Moreover, again on the virtualization host, I installed bacula to perform the backup of the data. Is it advisable/good practice to do so or should I create one more virtual machine to do backups and VPN? Is it a bad idea to run these services on the host itself? If yes, why? Thanks in advance!

  • Getting much higher than usual brute-force attempts on cPanel

    - by UserZer0
    Although I have many client accounts on my cPanel based server I'm really the only one who has login information to any of the accounts. I have cPhulk setup to alert me and blocking after 4 failed attempts. I usually have only a handful of bots trying to get in each day(2 hosts ago I never had any), but Today the rate has significantly increased, every 10 minutes or so(no not like clockwork, just averaging). Should I be concerned? Is there anything extra I should be doing, is there any automated reporting services I can use? Thanks.

  • How can I avoid logging file not founds commonly caused by vulnerability scanners?

    - by agweber
    My apache logs are pretty much full of 'admin.php' not found or unable to stat and similar statements for wp-login.php, default.php, and so on that are often sought after by vulnerability scanners. Can I configure apache to avoid logging these statements for certain files? I don't want to filter out all file not founds as I'd like to fix bad links that I may have put out over the years that no longer correspond to the same files. I can use a tool like fail2ban or denyhosts, but from previous experiences it comes from so many places that those errors are still going to pile up, and the reducing those error messages are what this question is asking about.

  • How do I check if a program can potentially be a virus?

    - by acidzombie24
    I am running Windows XP in a VM. I want to download a few applications and install the one by one and check if they potentially can be a virus. I assume virus would need to add something to the startup folder, or the application in the startup section in the registry or add a service. What else might it do to become active? Anyway, how can I check to see if a program may be a virus? I use hijack this to get a list of processes and I simply compare it from before I installed to after and see if there's anything different. Is this good enough? My main OS is Windows 7 but I do not have that in a VM and don't see a reason to test with that.

  • What is the most secure way to set up a mysql user for Wordpress?

    - by Sinthia V
    I am setting up Subdomain based MU on my domain.Everything is hosted by me running on one CentOS/Webmin VPS. Will I be better off setting the MySQL user's domain as localhost, 127.0.0.1 or with a wildcard %.mydomain.com? Which is more secure? Is localhost === 127.0.0.1? If not what is the difference? Also, what is my domain from MySQL's or Wordpress' pov when I am connected by ssh terminal? How about When I connect by Webmin or Usermin? Does MySQL see me as Webmin or my Unix user?

  • How can I limit other (administrator) users access to my profile?

    - by kojo
    Hi, We in our club have a computer with Windows 7 Professional that every club member may use. And everyone has their own separate account. Those accounts have to have administrator priveleges since I want everyone to be able to install any software and use any feature they want. However, there is a single thing that they shouldn't be allowed to do - that is, look into another users' profiles. Now when anyone goes to 'c:\Users(Any User Name)' a little prompt appears that this folder is secured and whether you really want to look inside. Simply clickinh 'ok' give you access to any profile. I tried disabling taking ownership for Administrators group in Group Policies but that had no effect. How can I effectively prohibit administrators looking into each others' profiles and documents?

  • Encrypt ONE system directory?

    - by acidzombie24
    I dont want to encrypt my whole hard drive. But one app i ENJOY using stores my password in a not so secure way in the AppData folder. I would like to encrypt the folder. One note is the folder is inside my user/name directory. Maybe that will help or hinder the solution. I am fine with encrypting all of AppData if necessary. However i prefer not to encrypt C:\Users\NAME\ since it is heavily used by many apps. C:\Users\NAME\AppData\Local\APPNAME

  • Preventing an Apache 2 Server from Logging Sensitive Data

    - by jstr
    Apache 2 by default logs the entire request URI including query string of every request. What is a straight forward way to prevent an Apache 2 web server from logging sensitive data, for example passwords, credit card numbers, etc., but still log the rest of the request? I would like to log all log-in attempts including the attempted username as Apache does by default, and prevent Apache from logging the password directly. I have looked through the Apache 2 documentation and there doesn't appear to be an easy way to do this other than completely preventing logging of these requests (using SetEnvIf). How can I accomplish this?

  • How I can view and block specific applications temporarily from accessing Internet?

    - by Curious Apprentice
    I don't want to block any application permanently from accessing internet. I just want to block some specific applications for a particular time period to gain speed in running some other. I know about one such great tool - that is "Comodo firewall". It can smoothly block and accurately display apps accessing internet. The only problem of installing this is, Windows recommends only one firewall apps and as Im running Windows 7 x64 Ultimate there will be complications if I install this one. I need a tool which can accurately display which apps are accessing internet (through which port) and how much data they are receiving or sending. I also need some arrangement within the app so that I can easily temporarily block that app from accessing internet.

  • What is the correct way to use Chef-server's 'validation key'?

    - by Socio
    It seems to me that the recommended way of adding clients to a chef server - or my understanding of it - is flawed. from the docs: When the chef-client runs, it checks if it has a client key. If the client key does not exist, it then attempts to "borrow" the validation client's identity to register itself with the server. In order to do that, the validation client's private key needs to be copied to the host and placed in /etc/chef/validation.pem. So the "validation key" is basically the superuser credential, allowing anyone who possesses it full access to the chef server? Am I reading this right? Surely the correct model would be for clients to generate their own keypair, and submit the public key to the chef server. Clients should never need access to this superuser "validation key". How can I do it in this, more secure, manner?

  • permissions on upload folder not working

    - by Camran
    I have a php script which uploads images to a folder. I have these permissions on the upload folder: drwxrwxr-- 4 user user 4096 2010-06-02 16:20 temp_images Shouldn't these permissions be enough for files to be uploaded to the folder? But this doesn't work. It only works when I set the permissions to 777. "user" is added to the www-data group, still no luck. Any ideas why?

  • Missed something? Cant upload files to server (permissions)

    - by Camran
    I can upload files as "root" to the Ubuntu server. Then I created a user (me). Next I added the user to the group www-data. Then assigned rwx permissions to www-data. Next, when I try to upload, delete or modify files VIA FILEZILLA, I cant. But via the terminal, I can change files using sudo command. What should I do to be able to upload files without getting the "permission denied" in filezilla? If you need more input let me know. Thanks

  • Is there a way to get Apache to blank sensitive data from logs?

    - by i..
    We're trying to clean up one of our systems as much as possible & have found that despite our attempts to block, users are accessing a certain part of our system through a HTTP GET with their password in the URL. This results in our Apache logs recording their password in plain text on the server. Is there an Apache directive or module that can filter out (or replace) certain patterns in its logs?

  • Why is the word PERSONAL still relevant in the term PC? [closed]

    - by Bill
    I have spent half an hour trying to change an icon on my Win-7-64 machine (Why Can't I Change the Icon). One reasonable suggestion (reasonable in terms of having a solution, not reasonable in terms of having to jump through these hoops for such a basic requirement) was to delete the old icon from the %userprofile% \ Local Settings..., however when I click on this folder in Windows Explorer I am told the folder is not accessible - Access Denied. Well! It's my PERSONAL computer isn't it? Isn't that what PC stands for? It's MY computer - why can't I get access to that folder? It's about time we started calling these machines MCs (Microsoft Computer), or WCs (Windows Computer) - because they sure as hell aint PERSONAL damn computers!!!!

  • Java process eating CPU; Why?

    - by Camran
    I have a Linux server which I have installed Java on. Sometimes, and only sometimes when a large nr of visitors visit my website, the site hangs. When I open the terminal and enter the "top" command to see whats going on, I can see that "Java" process is eating CPU! Like 400%. I have also tried ps aux command, and can see that the command is from usr/bin/java I have little experience in troubleshooting this kind of things, so I turn to you guys for help. I have a java container installed (Jetty) which I must have in order to use SOLR (search engine) which is integrated into my website. I can start and stop SOLR by: etc/init.d/solr stop But this didn't remove the java process from the "Top" command. Still java was eating 400% CPU. Is there other methods to restart java only? This has happened twice to me, and each time I have now restarted my entire servers and everithing is fine. If you need more input let me know! Thanks

  • most simple way to get files on a server

    - by acidzombie24
    I am on windows and my server is linux. I would like to grab files from the server automatically with a script. Maybe execute a bash script remotely as well but maybe i dont need that. I need to connect securely and i would like some kind of password so not anyone can connect. I need to download files and i'd like to get every file in a set of folders. I do not want to download them again if they exist. What is the easiest way to do this? i thought of creating a simple .NET site with data in App_Data (so it cant be reached from the outside) however i have a feeling an easier way exist. I'd like to do scp with a shell but i am on windows and also i am unsure how to iterate through folders and only get files that dont exist.

  • Is a VPN a good method for protecting data in an untrusted network? [closed]

    - by john
    I will be connecting my laptop in an untrusted network. If I setup OpenVpn on a server and use a vpn client on the laptop to connect through it, is it enough? Can someone perform a MITM attack or otherwise eavesdrop on my traffic? If someone on the local network port-scans my laptop, will the open ports be accessible to him while I use the VPN tunnel? Is there anything else I should keep in mind?

  • What are my options for a secure External File Share in Server 2008 R2?

    - by Nitax
    Hi, I have a Windows Server 2008 R2 machine installed on a home network with a number of files that need to be shared in a few different scenarios. I would like for all three scenarios to have a solution with some sort of encyption to protect the data during transfer. Scenario 1: I need to access files from my laptop (Mac OSX) or another computer outside of the network. This option seems like the easy one to answer in that I could use LogMeIn, the windows VPN, etc. to create such a connection. Scenario 2: I need to provide access to another user with minimal installation / configuration on his or her end. This makes me think of the new FTP 7.5 provided with Server 2008 R2 but i'm not sure of the details: Does it support SSH or some other form of encryption?, can an OSX user connect?, etc. My question here is what are my options? I really just don't know where to get started...

  • What are the minimal iptables rules to surf the internet?

    - by alexx0186
    I am trying to set minimal rules to my Linux iptables rules file to just be able to surf the internet. Here what I did: * filter -A OUTPUT -p tcp --dport 80 -j ACCEPT -A OUTPUT -p tcp --dport 443 -j ACCEPT -A OUTPUT -p udp --dport 53 -j ACCEPT COMMIT With just those rules, I can't surf the web. I noticed that when I put -A INPUT -j ACCEPT, it works but I don't understand why. So what Input/output port do I need to surf the internet? Thanks a lot. Regards EDIT: It still doesn't work and my rules as as follows: # generated by iptables-save filter :INPUT DROP [10:648] :FORWARD DROP [0:0] :OUTPUT ACCEPT [10:648] -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPTED COMMIT
