  • Free firewall for Windows Server 2003

    - by n00b_Admin
    We have a Windows Server 2003 R2 Machine here at work that I need to ensure is accessible only from specific set of IP Addresses. The Server is on a LAN and I am aware that one of the possible solutions maybe limit access to the Server's VLAN. However that is not feasible at the moment. I've been searching for a firewall that could do this, Windows' Firewall is pretty limited and I don't see an option in it to limit incoming data based on Source IP addresses. Most free firewalls like Comodo and ZoneAlarm don't work on Windows Server. Any ideas on how to accomplish this would be of great help. Thanks in advance.

  • Monitor someone on server

    - by edo
    Im in the unfortunate position of having to give someone who I do not fully trust privileged access to a webserver to finish work that they never completed. They will access the server remotely (ie I will not be able to see their screen). What can be done to a) proactively limit any potential damage and b) accurately log anything they do on the server for analysis afterwards, even if things seem ok? They will be updating a web application. Thanks in advance! --- More informtion: The server is a Ubuntu AWS server.

  • VPS name server

    - by rockey
    I bought a new VPS, and configured two applications test1.com and test2.com on ngix server, now I can access both the application inside VPS, Now I need to invoke the application from other machines. MY domain is registerd with Enom, So I added 'A' name pointed to IP address of the VPS, Currently my VPS is not providing any Name Server, So what steps need to be done to resolve the issue regarding Name Server so that i can externally invoke the domains like www.test.com and www.test2.com from other machines? Is any configuration is left from my side other than configuring the Name Server? because it is not working now Thanks in advance

  • Secure email folders on a Linux server

    - by Moutaz
    Hi; I was astonished when I knew that any one can read emails on a Linux server if they new where to look even if they didn't have the email password just the Cpanel password. The question is: How can I secure these emails while on server before being downloaded? I have a Linux server with exim WHM/Cpanel Thanks.

  • iptables to allow input and output traffic to and from web server only

    - by Caedmon
    I have an Elastic Search server which seems to have been exploited (it's being used for a DDoS attack having had NO firewall for about a month). As a temporary measure while I create a new one I was hoping to block all traffic to and from the server which wasn't coming from or going to our web server. Will these iptables rules achieve this: iptables -I INPUT \! --src 1.2.3.4 -m tcp -p tcp --dport 9200 -j DROP iptables -P FORWARD \! --src 1.2.3.4 DROP iptables -P OUTPUT \! --src 1.2.3.4 DROP The first rule is tried and tested but obviously wasn't preventing traffic coming from my server to other IP addresses so I was hoping I could add the second two rules to full secure it.

  • Server is sending SPAM but it's not an open relay

    - by alexandernst
    I have a problem with Dovecot + Postfix. My server is sending SPAM from the local user "dovecot", but my server is not configured as an open relay (mails can be sent without auth-ing only from localhost). Also, nobody except me, has SSH access to the server. How can I find what exactly is triggering all those SPAM mails? How can I get something like a backtrace that shows what exactly happened the moments before a SPAM email got in the queue of postfix? Regards

  • Can't reach server without proxy (website down from my home)

    - by user2128576
    I have a website hosted on Hostinger However I am experiencing problems with my wordpress site. This is really annoying. If I understood the situation right, The server is blocking me or denying access to my own website. When I visit the site with google chrome, it returns: Oops! Google Chrome could not find Same thing happens to firefox! Firefox can't find the server but when I do a check if my site is online and working through http://www.downforeveryoneorjustme.com/ it says that the site is working and up. Another thing, I access the website through a proxy, both on chrome and in firefox, and t works. Why is this? I have also recently installed the plugin Better Wp Security 5 days ago. Could the plugin have caused it? but I don't remember setting any IP's to be blocked. Also, this happens at random times, sometimes I can access it, sometimes it fails to reach the server. I am currently developing the site live. Was I blocked by the server for frequently refreshing the page? (duh, I'm a developer and I need to refresh to see changes.) or is this a problem with my ISP's DNS server? How can I resolve? and what are the possible fixes? Thanks in advance! -Jomar

  • Script to restart server when no user is remotely connected

    - by RitonLaJoie
    I'm looking for something special : here is a windows server that is used for development by 4/5 people remotely working on it through remote control. I'm installing Visual Studio 2010 on it, and the installation won't continue until the server has been restarted. I'm looking for a way to reboot when the server is idle (when nobody is connected through remote desktop on it) so that the reboot doesn't bug anyone. Is there some software that can do that ? Thanks !

  • trouble accessing mail server from outside domain

    - by cinqoTimo
    Our organization just moved our Website/Domain to a hosted VPS. We elected, for the time being, to keep our email (Exchange) running at our office. On our new VPS, we simply add a DNS record to redirect our mail to our on-site exchange server. This worked out well, as mail is coming and going with no problems. Recently, we ran across an issue when setting up outlook from outside of our office (Not on same network as exchange server). When configuring mail server address, it keeps prompting for credentials. Anyone got any ideas on why this is happening? Is our VPS not allowing Outlook to find our exchange server? If so, how can we bypass it?

  • Cannot Access Server from External IP (Router)

    - by mindoftea
    We have an Ubuntu 10.04 LAMP server running on site (Apache is on port 80). It is running fine through the LAN, but I cannot access it using its external IP address through the Netopia 3000 Series modem by which it is connected to the internet. I have tried using what Netopia calls "Pinholes" (Port Forwarding) to make the server accessible, but a telnet to the external address just gives me "connect to address x.x.x.x: Operation timed out." I have also tried enabling "Services" and "IP Passthrough" on the router, but it gives the same result as above. How can I enable the server to be accessed through its external IP address? Because it connects fine locally, it would seem to be a problem with the Netopia router. Update: Booting the server in GUI mode instead of text mode solved the problem instantly. Any ideas why?

  • How to set up server to be accessed from mobile devices [closed]

    - by Kgrover
    I need to set up a server that will eventually be accessed from an Android application. I don't have experience with how to go about this, but I've seen MySQL servers (Amazon EC2). I would need to store data on the server remotely (again, from a mobile device) and fetch it to display. What would be the best kind of server to use? I'm guessing I would only need around 50 GB of space. Is it possible to use a network drive and set that up as a remote server with an IP address? I would need to upload and extract data through java on Android. This is my first question on ServerFault, and I'm not sure if it's the appropriate forum. If not, please redirect me.

  • Setting up a local mail server

    - by KriiV
    This is what I want and I am having issues finding a solution. I have a number of websites (around 5) each with an email account. I have a server at my office and I would like to centralize it. I have a workstation too. What I want to happen is for the server to receive all emails from all those websites (from the web servers) and then connect my workstation to my local server to grab the emails from there. As the server downloads the emails, I would like them to be stored. Also, if I connect another workstation, I want the 2 workstations to sync. So if an email is read on one, it shows up as read on the other. Ideas? I am able to virtualize a Linus environment if that helps.

  • Open source monitoring tool without sending data to "Their Server"

    - by hangu
    I trying to use open source server monitoring tool. I know there are a lot, but I couldn't find what I need.. the basic process of monitoring tool I used to use before was, 1) Install agent in my server which I want to monitor 2) The agent send data to "their server" 3) I can check the health of my server through web browser presented by them. What I need is, avoiding "Step 2". Are there any monitoring tool that I can use? I have Windows 2008 and Linux servers simple feature will be enough like (CPU, Memory, Network..) Thank you

  • Debian virtual server hangs on reboot, need help debugging

    - by BubuIIC
    I'm admin of a Debian 6 virtual server. I've been trying to diagnose this problem for a while but haven't gotten anything. The server hangs every time I want to reboot it. All services seem to be shutting down, I lose ssh connection. Then nothing. I have to restart it through the hoster's web-interface, which just gives me the options "Normal Boot" and "Rescue System". Normal boot then brings the server back to life. Possibly (probably?) related, the server does not boot into a newer kernel version, it's running 2.6.18 right now, but installed is actually 2.6.32. I don't know whether it hangs on shutdown or on startup, but booting through the web-interface works (except the kernel part). Am I missing something obvious? Where should I start looking? I have no idea how to diagnose the problem.

  • Server access through switch port

    - by Kblz Btz
    I am using wireshark to monitor traffic on a server - Problem is, the computer I am using is only a terminal wired through the switch. Main line comes into the server which is relayed to multi-port switch (roughly 50 connections). Right now I get a lot of server communication between my it and my terminal but shows no information for other terminals. Can wireshark be configured to monitor ALL traffic in this environment?

  • tar gzip slowing down server

    - by Josir
    I have a backup script that: compress some files generate md5 copy the compressed file to another server. the other server finishes comparing MD5 (to find copy errors). Here it's the core script: nice -n 15 tar -czvf $BKP $PATH_BKP/*.* \ | xargs -I '{}' sh -c "test -f '{}' && md5sum '{}'" \ | tee $MD5 scp -l 80000 $BKP $SCP_BKP scp $MD5 $SCP_BKP This routine got CPU at 90% at gzip routine, slowing down the production server. I tried to add a nice -n 15 but server still hangs. I've already read 1 but the conversation didn't help me. What is the best approach to solve this issue ? I am open to new architectures/solutions :)

  • What is the best plan to handle server fault for google app engine [closed]

    - by lucemia
    I used google-appengine without preparing much backup plans before, but it looks like not a good idea anymore.... Since google app engine is quite hard to find a backup replacement, I plan to just add a "server error" page which will show while server fault. Currently I am thinking to: Use the cdn cloudfare in front of google app engine. It will also handle the NAME server for me. Prepare some static version of webpages (such as "Oops! the server fault") in another hosting platform While google app engine failed, I will switch the destination from google app engine to the static page by change the CNAME records on cloudfare. Is there any other recommand way to solve this situation?
