• Iptables to lock down compromised server to a single ip

  - by ollybee

  I have a Linux server which is compromised, I can see nasty looking perl scripts executing with root privileges. I want to get some data off it before I wipe it. How can I block all inbound and outbound traffic except for my ip? It's a Centos server I assume i can do this with iptables? I'm aware a the server is rooted there is a possibility that attackers could have made changes on the server that would prevent this from working. Ill be testing to make sure and only have the server online for a couple of hours before it is nuked.

• Moving to Data Center

  - by Won

  Please, give me any advice. Our company has decided to move servers to a data center since we are having a major network traffic jam. The data center provides 100MB bandwidth and full 42 unit cabinet for us. Right now, I am planing to have two firewalls for a failover and changing DNS informations for a web server. Is there anything that I have aware of before I move them to the data center? 1. Web Server 2. Exchange Server 3. SQL Servers

• Users own mapped network drives disappear when I set a GPP mapped drive

  - by Kim

  All the clients use Windows 7 SP1 x64 Enterprise. The domain controllers are Windows Server 2008 R2. I have configured the GPP to map "\server\data" to first available drive letter starting with I:. The action is replace and I have set the Hide/Show this drive and Hide/Show all drives to "Show". I have set targeting to a specified security group. This works as expected and the drive is mapped to the correct users. The problem is that if the user has created their own mapped drives these mappings will disappear when the GPP mapping is applied. Only the mapped drives from the GPP is shown in Explorer. I have not found any other mention of this particular problem when I search the Internet and on TechNet there is no mention of what happens to drives already mapped.

• Apache routing vhosts to /var/www

  - by FHannes

  One user at my site has reported that he reaches the content at /var/www when browsing to any of the vhosts at my server. As far as I’m aware, my Apache server does not contain a document root that references this folder. On top of that, this user seems to be the only one experiencing the issue. According to his ISP, the issue isn’t caused by them, yet, on his mobile connection, he can access the site. When browsing to my server’s IP, he also receives the correct content from the default vhost. What could be the possible causes of this issue and how can I get it to stop? I’ve explored pretty much every option I could think of.

• hosting website on a private network

  - by razor

  i'm currently running a website off 3 linux servers. I'd like to setup a private network and only allow port 80 traffic to one of the servers. I'd also like to setup a vpn so only I can access the servers via ssh or any port for developing/debugging. How hard is this to setup and what do I need to get? Do enterprise/commercial routers have vpn functionality built in? how do I handle DNS? eg- www.mydomain.com would need to point to the router, which forwards traffic to the webserver. Do I set the A record to the router, and somehow tell the router which server to send the http request to? And how would I make server1.mydomain.com resolve to server1 within the private network (without editing host files)? Would I need to run my own DNS (eg- powerdns?) to do this?

• How to monitor RAM usage for Hyper-V VMs ?

  - by Mac

  A bit of context first : on Windows 2008 Standard x64 with 8Gb RAM, I have 5 VMs running which should take up 1664Mb RAM (3*256Mb+384Mb+512Mb). There is nothing else running on this server except the basic OS components (this not a Core installation). I know that each VM will use more RAM on the host than what has been configured in Hyper-V. But when I run the task manager, it says 6.7Gb used ! If I sum up the RAM used by each process in the task manager (showing all users processes), I get to something around 1Gb... So : how can I check how much RAM each VM is really using on the host (it does not seem to be available via task manager) ? Note that I am aware of the fact that my problem could be unrelated to VM RAM usage, but I would still very much like to know how to do this.

• Sticking with Ubuntu 12.04 while heavily using PPA for newest software updates (Apache 2.4, PHP 5.5)

  - by MechaStorm

  I was wondering whether is it worthwhile to stick with Ubuntu 12.04 LTS until 14.04 comes or should I be switching to just the latest Ubuntu server version 13.10. My server needs are not enterprise heavy and previous thought to keep with LTS was simply to gain the security updates without having to upgrade the servers every couple months. But as we are moving forward with our software development, I have found that alot of the default version of software with 12.04 is way out of the date forcing me to up date via PPA or from source instead of from default apt-get. ie PHP 5.3 is on 12.04, and I'd like to get it to 5.5. Is it worthwhile to simply move to 13.10 in that situation? With the idea to move to 14.04 when it comes?

• How to effectively secure a dedicated server for intranet use?

  - by Mark

  I need to secure a dedicated server for intranet use, the server is managed so will have software based security, but what other security should be considered for enterprise level security? The intranet is a host for an ECM (Alfresco) managing and storing sensitive documents. As the information is sensitive we are trying to make it as secure as reasonably possible (requirement in UK law). We plan to encrypt the data on the database. It will be connected to via SSL encryption. Should we consider Hardware firewall, Private lan between the application server and database server?

• Lock manager stops responding (lockd/nfslock), but shows as running

  - by dwaynehoov

  Essentially, lock manager stops responding (lockd/nfslock), but shows as running as a kernel process. If I bounce portmap and nfslock, it has no effect. Doesn't show up in the portmapper registered services rpcinfo -p .. doesn't show nlockmgr. it just shows portmapper and status If I manually remount the drives, it fixes the issue. I'm assuming that the service (lockd) goes stale or hangs when there is no NFS activity? It seems like issuing a mount for NFS volumes "awakens" it and things work once that happens. Please help me nail this down for point me to somewhere to get more information on what might be happening. System info: Linux xxx.yyy.com 2.6.32-300.38.1.el5uek #1 SMP Thu Oct 18 11:51:13 PDT 2012 x86_64 x86_64 x86_64 GNU/Linux cat /etc/redhat-release Red Hat Enterprise Linux Server release 5.8 (Tikanga) cat /etc/oracle-release Oracle Linux Server release 5.8 Thanks

• Ctrl-Alt-F1 never gives prompt

  - by nispio

  When I press Ctrl+Alt+F1 in my Red Hat Enterprise Linux 6.4 (Santiago) I get a black screen with a blinking cursor, but I never get a login prompt. I can get back to my desktop with Ctrl+Alt+F7, and things work as normal. However, when I run sudo init 3 I get the same thing, but this time I am stuck at the screen and can't get back without a reboot. I'm not even sure where to start looking for the cause of this problem. Are the startup scripts that might be causing the problem or other system configurations that could lead to this? If this is not an known issue, what steps should I take to debug?

• Mac OS X multi-user thin client server (terminal server)?

  - by username

  Is there any solution out there to turn a Mac into a true multi-user thin client server? I'd like to set up a few cheap PCs with access to a couple accounts using something like VNC, but it isn't economical to buy a new server for each user or a new license for virtualized OS X Server for each user. I'm fully aware that OS X Server lets you set up users with "network home folders," and I know there's also VNC built into Mac OS X. Neither of these fit the bill (the former requires a thick client, and the latter is single-user only) UPDATE: yay, Lion! http://www.9to5mac.com/54102/10-7-lion-allows-multi-user-remote-computing

• How to batch rename files based on file header/metadata in Windows?

  - by Infraded

  I have a directory full of randomly named files of different types, all with no file extensions. Most are images, with some videos, and some plaintext. I've used one of the Windows versions of file to confirm the files can all be identified by their headers/metadata, but would like to automate the naming as there are roughly 2400 files. I don't care so much about the filename as much as just having the appropriate extension for it's type. Is anyone aware of a program or script that can do this?

• Open table cache in MySQL

  - by vvanscherpenseel

  I have my open table cache set to 1800 and I have a total of 1112 tables. MySQL Tuning Primer reports that 100% of my table cache is used yet my table cache hit rate is 5%. I understand that this happens due to concurrent connections all opening tables. I think I should raise the cache limit. I understand that the cache size is limited by the file descriptor limit of my operating system, but are there any other practical limitations I should be aware of? Searching Google or this very website yields mostly posts explaining the connection-factor or come up with indecisive answers. My question: can I safely increase the open table cache limit? Is there a maximum?

• Everything You Ever Wanted to Know about Mod_Rewrite Rules but Were Afraid to Ask?

  - by Kyle Brandt

  How can I become an expert at writing mod_rewrite rules? What is the fundamental format and structure of mod_rewrite rules? What form/flavor of regular expressions do I need to have a solid grasp of? What are the most common mistakes/pitfalls when writing rewrite rules? What is a good method for testing and verifying mod_rewrite rules? Are there SEO or performance implications of mod_rewrite rules I should be aware of? Are there common situations where mod_rewrite might seem like the right tool for the job but isn't? What are some common examples?

• 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.

• Proxy server modifying request/response upon pass through

  - by jamiei

  I would like to set up a non-transparent proxy server that will selectively modify HTTP requests and responses as it passes them through. The motivation for wanting to modify the data on the fly and not at the original source are not part of the question. I'm hoping there is a solution which allows the modification scripts to be written in a mainstream programming language. I am aware of guides for Squid which allow you to flip images etc on the way through but I was hoping for a slightly more established and less hackish solution. Does anyone know of an established open source project or environment (Any major platform) which would allow me to script in arbitrary modifications to the data being passed through?

• reclaim space after moving indexes to file group

  - by Titan2782

  I have an extremely large database and most of the space is the index size. I moved several indexes to a different file group (just to experiment) but no matter what I do I cannot reduce the size of the MDF. I tried shrink database, shrink files, rebuilding clustered index. What can I do to reclaim that space in the MDF? I've moved 15GB worth of indexes to a different file group. Is it even possible to reduce my mdf by that same 15gb (or close to it)?

• Cache that always returns immediate response?

  - by Col Wilson

  I have a web service that takes a while to build a response despite being tuned as best I can. What I'd like is some sort of cache sitting in front of the service which would always return the last known value from the service, but at the same time pass the request back to the service to build an up to date response for the next request. I'm aware of the limitations that this puts on the freshness of the data, but you can assume that I'm happy to live with that. The technologies I'm using at present are python uwsgi via nginx, but that need not be a limit to any solution you might suggest. Col

• Solaris NFS: user permissions

  - by cjavapro

  I am very new to NFS. I would like to make sure I am clear. If the NFS server shares a directory rw,, and all the files in the directory are permissions 700 and user/group for those files is root/root,,, On the client you would have to log in as root to see it. Is this correct? I am aware that a non root user on the client could make a direct connection to override this. (as in don't use the mount, just use an NFS client hack.) It really seems like anyone who has access to the client machine should have access to the files and that the client machine should be ignoring permissions. Only the server should handle permissions. Am I correct in my understanding? Is it normal to have this type of layout? Is there a way to ignore the permissions on the client side?

• Are there web search engines with exact match or regex capabilities (for related terms)?

  - by naxa

  Every once in a while I come upon a situation when google's way of searching results in too broad results even if I enclose my search terms in quotation marks. For example now I've tried to find pages that contain both "py.path" and "path.py" without much success. I'm currently aware of engines|sites like Google Code Search for searching actual code and (apparently) Stackoverflow for searching QAs, symbolhound that lets me find symbols, and also wikipedia is often a good place to find lists of symbols. But none of these seems to perform very good in matching exactly on search term pairs (or tuples) and use a broad-enough segment of the web. Is there a website that is good with exactly finding search term pairs? (Why not?)

• Will readyboost speed up a secondary partion or harddrive?

  - by Sebastian

  I'm building a new computer and plan on using a few spare USB sticks with readyboost to cache disk writes. I'll be running Windows 7 Enterprise SP1 x64 I have a single 2 TB disk, and plan to make a partition for windows (100 GB) and use the rest for data. I know Readyboost will work nicely for the C drive, but am unable to find any information on whether it will accelerate a second drive or partition. Just to clarify, I'm NOT trying to use the harddrive instead of the usb sticks. I'm trying to speed up the second partition using the USB sticks So, will readyboost work for a secondary partion or harddrive?

• What Filesystem should be used for a 4TB drive for both Windows and OSX compatibility? [closed]

  - by Nicholas Yost

  Note: I am aware of similar questions. The one's I seen here are for Windows, OSX, and Linux (which I do not need). I also can use Mountain Lion, which the other questions did not mention. I was going to use NTFS, but OSX Mountain Lion can only read that filesystem and not write to it for some reason. I want to use something native between OSX and Windows, as I don't want to risk losing the data over filesystem incompatibilities. I have USB 3.0 and want something that will allow files greater than 4GB. I do not mind installing a small set of drivers on the Windows machine(s), but I would strongly prefer to leave the Mac machine untouched. Thanks!

• Manage Kickstart library with Puppet

  - by Tim Brigham

  I maintain a library of different kickstart configurations, mostly for CentOS 5 and 6. It has recently gotten to the point I want to deduplicate as much of this information as possible. I am aware of a couple options out there which can dynamically generate kickstart files. Not interested at this point unless I really need to do that route. I would like to create my Kickstart files using a template along the following line: deploy1-centos5.erb .... install=http://.../$arch/... repo=http://.../$arch/... .... My output naming schema is "deploy1-centos5-x86_64". I'd like to be able to create several kickstart files from a given template, one for 32 bit, one 64, ppc, etc. This would work perfectly if I could readily set the value of arch per each time the template is called to create a file. What is the most ready way to address this?
