• Amazon AWS Ec2 instance, Elastic IP, Domain name from external domainseller, and Google Apps for Email

  - by Sid

  We are hosting our site on an Ec2 instance. Our Elastic IP is w.x.y.z and Public DNS is: ec2-w-x-y-z.compute-1.amazonaws.com. We've bought a domain name domainname.com from a lesser known domain-name-seller. We added an A-record pointing domainname.com to w.x.y.z. Will this work or do we need a CNAME record to point to the same too? We wanted to use Google apps for emailing so adjusted the TXT/MX records according to the Google Apps instructions to be able to send/recv email using @domainname.com email addresses. Have we got it right, more important, we came across queries relating to email sent from ec2-w-x-y-z.compute-1.amazonaws.com (our users can send email from their onsite accounts) going to spam (rDNS not pointing to domainname.com but to ec2-w-x-y-z.compute-1.amazonaws.com). How can we fix this? We came across SPF records, do they provide a complete solution? We aren't sure as to how to use them. Can you help pls? Thank you, Sid

• Troubleshooting wireless connection problem / site survey?

  - by johnnyb10

  I just started in the IT department of a small company (200 users) and it's clear that one of the main problems that is driving everyone crazy is the spotty nature of the wireless connectivity throughout the office, particularly in certain conference rooms. This is a huge problem because the connection often drops during important presentations to clients. I was hired to help ease the load on the existing IT admin, who has done a great job, but is overloaded with many other tasks to deal with. So I would like to try to help out with this wireless issue. I am looking for advice on the best way to solve this problem--a realistic troubleshooting methodology that does not require me to spend any money. So far, I've experimented with Ekahau Heat Mapper, which is free and helps create a site survey. But I'm not exactly sure what I'm looking for or if there are other programs/tools/methods I should try as well. Any advice would be greatly appreciated. [Some background: The wireless setup consists of an HP ProCurve Mobility MSM (710?) controller that controls 10 access points throughout the building. There are three virtual wireless networks configured on the controller: one seems to be a default that cannot be changed, one is for internal employees and authenticates via Active Directory, and the third is a guest network for visitors. When I use HeatMapper, these show up as three different SSIDs, with different MAC addresses, all on the same channel. At first I thought maybe this would cause interference, but this seems to be the way the controller works;apparently, it automatically configures the channels to avoid interference from the other APs on the network.]

• Gmail notification in Ubuntu's native mail icon.

  - by D Connors

  So, new Ubuntu 10.04 up and running. Playing with the interface eventually got me curious about something. Up until now, I've only used the chat and broadcasting functionalities of the mail icon in Ubuntu's top panel, mostly because I take care of my mail on firefox so I don't need one more program (empathy) running on my poor little netbook. I'm currenty using gnome-gmail to set gmail as my default mail client in Ubuntu. But, when I click on the "Set up mail" item, inside the Panel's Mail icon, it simply brings up empathy. My question is: Is it possible (in any way whatsoever) to have my gmail notifications up there, configured so that clicking it will just take me to a gmail tab in Firefox? (instead of opening up empathy) This is really just some frivolous interest of mine, nothing important. Right now I'm using check-gmail to notify me of new mail, but the panel is really cramped up on my netbook, so it'd be nice to free up some room by getting rid of check-gmail and only using Ubuntu's mail icon. Ok, hope I was clear enough.

• How to count the most recent value based on multiple criteria?

  - by Andrew

  I keep a log of phone calls like the following where the F column is LVM = Left Voice Mail, U = Unsuccessful, S = Successful. A1 1 B1 Smith C1 John D1 11/21/2012 E1 8:00 AM F1 LVM A2 2 B2 Smith C2 John D2 11/22/2012 E1 8:15 AM F2 U A3 3 B3 Harvey C3 Luke D3 11/22/2012 E1 8:30 AM F3 S A4 4 B4 Smith C4 John D4 11/22/2012 E1 9:00 AM F4 S A5 5 B5 Smith C5 John D5 11/23/2012 E5 8:00 AM F5 LVM This is a small sample. I actually have over 700 entries. In my line of work, it is important to know how many unsuccessful (LVM or U) calls I have made since the last Successful one (S). Since values in the F column can repeat, I need to take into consideration both the B and C column. Also, since I can make a successful call with a client and then be trying to contact them again, I need to be able to count from the last successful call. My G column is completely open which is where I would like to put a running total for each client (G5 would = 1 ideally while G4 = 0, G3 = 0, G2 = 2, G1 = 1 but I want these values calculated automatically so that I do not have scroll through 700 names).

• Lock down Wiki access to password only but remain open to a subnet via .htaccess

  - by Treffynnon

  Basically we have a Wiki that has some sensitive information stored in it - not the best I know but my predecessor set it up. I want to be able to request password access from any one who is not on the local network subnet. Those on the local subnet should be able to proceed without entering a password. The following .htaccess does not seem to work any more as it is letting non-local access without requiring the password: AuthName "Our Wiki" AuthType Basic AuthUserFile /path/to/passwd/file AuthGroupFile /dev/null Require valid-user Allow from 192.168 Satisfy Any order deny,allow And I cannot work out why. The WikkaWiki it is supposed to be protecting was recently upgraded, which clobbered the .htaccess file so I restored the above from memory/googling. Maybe I am missing an important directive? The full .htaccess is as follows: AuthName "Our Wiki" AuthType Basic AuthUserFile /path/to/passwd/file AuthGroupFile /dev/null Require valid-user Allow from 192.168 Satisfy Any SetEnvIfNoCase Referer ".*($LIST_OF_ADULT_WORDS).*" BadReferrer order deny,allow deny from env=BadReferrer <IfModule mod_rewrite.c> # turn on rewrite engine RewriteEngine on RewriteBase / # if request is a directory, make sure it ends with a slash RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^(.*/[^/]+)$ $1/ # if not rewritten before, AND requested file is wikka.php # turn request into a query for a default (unspecified) page RewriteCond %{QUERY_STRING} !wakka= RewriteCond %{REQUEST_FILENAME} wikka.php RewriteRule ^(.*)$ wikka.php?wakka= [QSA,L] # if not rewritten before, AND requested file is a page name # turn request into a query for that page name for wikka.php RewriteCond %{QUERY_STRING} !wakka= RewriteRule ^(.*)$ wikka.php?wakka=$1 [QSA,L] </IfModule>

• Can't connect two PCs to a Network Switch at the same time (Windows 7)

  - by puk

  I have two computers connected to a network switch and every once in a while one of the computers will lose its internet connection. It's almost always the same computer every time. However, if I play around with the control panel, I can switch it, so that now the other computer is not connected. Restarting either of the computers does not help either. In Windows, the worlds-greatest-trouble-shooter tells me that a network cable is unplugged and that I should try plugging it in...Disabling and re-enabling my NIC does not fix this problem, neither does swapping cables around. When rebooting, the BIOS complains about how the Ethernet Cable is not plugged in. If it's in any way important, My set up at the office is like so: Modem - Routher - Network Switch 1 - Network Switch 2. I have tried turning off the energy saving option for my NIC, and I tried manually setting the link-speed to 100Mbps Full Duplex without any luck. Also, I have a Realtek PCIe GBE Family controller on both computers Does anyone have any idea why this is happening every 5-10 days? EDIT: I have also tried using a completely different Network Switch and the problem still persists as before.

• cygwin sshd times out for remote login

  - by reve_etrange

  I have configured SSHD using Cygwin on Windows 7. I have checked and double-checked all of the following points: Port forwarding is correctly configured Windows Firewall is configured to pass port 22 Local login attempts (using Cygwin SSH) succeed sshd_config has UseDNS No Using nmap from remote machine confirms port 22 is accessible /etc/passwd and /etc/group are correctly populated However, remote login attempts time out. This includes from the local network. user@host:~$ ssh -vvv [email protected] OpenSSH_5.5p1 Debian-4ubuntu6, OpenSSL 0.9.8o 01 Jun 2010 debug1: Reading configuration data /home/user/.ssh/config debug1: Applying options for * debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to the.ip.add.ress [the.ip.add.ress] port 22. debug1: connect to address the.ip.add.ress port 22: Connection timed out ssh: connect to the.ip.add.ress port 22: Connection timed out No messages are logged to /var/log/sshd.log.

Can anyone point me to a possible solution?

• Socket options for a tcp server with 3G clients & frequent disconnections

  - by Joel

  I have a TCP server, written in java, sending and receiving many short messages, from 500 bytes to 100 KB long. It's a chess game and chat server, to make it simple. The server is running Debian 6. Half of the clients are connecting from 3G networks, and half over standard DSL. A portion of the 3G clients lose connection pretty often. The error I get on the server and on the client socket is Connection reset. I have come across this page at Oracle documentation: socketOpt. I am wondering what I could tune there to lower the number of disconnections from 3G clients. I don't mind about the ping or transfer rate, but just about the TCP disconnections. I am not skilled enough to understand the impact of each setting, but I sort of understood that the TCP window was important, although I don't know exactly how. So I'm asking if anyone here has an idea ? Thanks if you can help.

• how to cause linux system datetime to run faster than real world datetime?

  - by JamesThomasMoon1979

  Background I want to monitor a running linux system over several days. It's a custom gentoo build and with much custom software on board. This software has ongoing maintenance timers and cron scripts and other clock driven events. I need to verify these scheduled events are working. Problem Waiting for the system to step through daily and weekly activity is a long wait time. And modifying all clock-based timers on the system would be time consuming. Yet, I often want to test a system's end-to-end scheduled activities without waiting a week. Potential Solution Have the linux system under test appear to run through it's daily cycle of activity within just a few hours. My Question for Serverfault Is there a way to cause the system's time to run faster than real world time? My first thought is manipulating the ntp daemon to repeatedly and smoothly increment the clock . Any other ideas? And yes, I know this may have strange side affects. However, the system has no important or time critical interactions with systems outside of itself. And this may be a valuable testing technique.

• Does Windows 8 RTM Support VB6 (SP6) Runtime files? If so, which ones?

  - by user51047

  Basically, I'm trying to find out which of the following files come packaged with the Windows 8 RTM (that is, the final version). Just to be clear, we're not wanting to know if any of the runtime files (listed below) are or were included with any of the previous versions (Beta, CTP, RS etc) or releases of Windows 8 - we are just interested in this compatibility question as far as Windows 8 RTM (Final Version) is concerned. In addition, if possible, we would also like to know which of the below files (if any) come shipped and registered with the Windows 8 RT (on ARM) version. As far as the ARM version is concerned, you're welcome to base your answer on the latest version of Windows 8 RT (on ARM) that is available at the date and time your answer is posted. (This will also serve to future-proof this question as additional releases or versions of Windows 8 and Windows 8 RT on ARM come out). Here are the list of files (which are basically the VB6 SP6 runtime files): File name Version Size Asycfilt.dll 2.40.4275.1 144 KB (147,728 bytes) Comcat.dll 4.71.1460.1 21.7 KB (22,288 bytes) Msvbvm60.dll 6.0.97.82 1.32 MB (1,386,496 bytes) Oleaut32.dll 2.40.4275.1 584 KB (598,288 bytes) Olepro32.dll 5.0.4275.1 160 KB (164,112 bytes) Stdole2.tlb 2.40.4275.1 17.5 KB (17,920 bytes) Of course, the most important file in there is MSVBVM60.DLL, so if you cannot provide details for all files relating to both Windows Releases, then basing the answer on as many of the files possible would also be useful. Thank you for reading and for your anticipated assistance in putting this question/answer on record.

• Remote desktop solution where the desktop sharing party contacts the computer it wants to share with

  - by Kent

  I'm in a situation where I act as a sort of techinical support to my family and less techinically experienced friends. I'm looking for a remote desktop solution where it's possible to setup a "zero-install, double click an icon"-solution where the client computer contacts me so that I may interact with their desktop. The last part is important as the people in need of my help don't know how to configure their router or even the firewall software on their own computer. They are able to click an accept button when asked if a program should be able to make outgoing connections. They have many different kinds of routers, as well as software firewalls, and I rather not deal with the problem of how to connect to them using whatever as well as the actual problem they are having. It must be: Free of charge for non-commercial use. Possible to use it in a mode where the computer wanting to share its desktop should be able to make a connection to my computer. My computer has a DNS name we can use. Compatible with both Windows XP and Windows 7. Independent of a third party server or infrastructure. Explanations of the above: I don't want to spend money on it when I help them for free. If it's free as in freedom, all the better! I guess this boils down to being callable like showdesktopto.exe opscomputer.com where opscomputer.com is my computers DNS name. If that is possible then I can create a shortcut they can use to connect to me when they need help. It's nice if it's possible to specify a password or key file which I can use to authenticate myself, but it's not required. They use the OS which their machine comes installed with. That means Windows XP or 7. I want something which will work in the long run. Using a third party service which might not be available when I need it disqualified such solutions.

• Apache2 with lighttpd as proxy

  - by andrzejp

  Hi, I am using apache2 as web server. I would like to help him lighttpd as a proxy for static content. Unfortunately I can not well set up lighttpd and apache2. (OS: Debian) Important things from lighttpd.config: server.modules = ( "mod_access", "mod_alias", "mod_accesslog", "mod_proxy", "mod_status", ) server.document-root = "/www/" server.port = 82 server.bind = "localhost" $HTTP["remoteip"] =~ "127.0.0.1" { alias.url += ( "/doc/" => "/usr/share/doc/", "/images/" => "/usr/share/images/" ) $HTTP["url"] =~ "^/doc/|^/images/" { dir-listing.activate = "enable" } } I would like to use lighttpd in only one site operating as a virtual directory on apache2. Configuration of this virtual directory: ProxyRequests Off ProxyPreserveHost On ProxyPass /images http://0.0.0.0:82/ ProxyPass /imagehosting http://0.0.0.0:82/ ProxyPass /pictures http://0.0.0.0:82/ ProxyPassReverse / http://0.0.0.0:82/ ServerName MY_VALUES ServerAlias www.MY_VALUES UseCanonicalName Off DocumentRoot /www/MYAPP/forum <Directory "/www/MYAPP/forum"> DirectoryIndex index.htm index.php AllowOverride None ...

• Can an image based backup potentially corrupt data?

  - by ServerAdminGuy45

  I'm considering doing image based backups (Acronis) on production Windows systems during non-peak hours. I'm just wondering if they can potentially lead to application data corruption. Lets say that I have a database that is getting hit pretty hard. Could I potentially have the beginning blocks of the database be commit ed to the image, data inserted into the db (which changes the beginning blocks of the DB on the server but not the image), then the blocks of data committed to the image (leading to an inconsistent state). Here's an example of what I'm trying to illustrate. Imagine a simple data structure which has a number in the front which represents the number of "a"s in a file. The number and data are delimited by a "-". For example: 4-ajjjjjjjajuuuuuuuaoffffa If an "a" is changed, the datastructure resets the number in the begining of the file such as: 3-ajjjjjjjajuuuuuuuboffffa I assume acronis writes block by block being a straight up image so here is what i'm invisioning happening with my database t0: 4-ajjjjjjjajuuuuuuuaoffffa ^pointer is here t1: 4-ajjjjjjjajuuuuuuuaoffffa ^pointer is here (all data before this is comitted to the image) t2: 4-ajjjjjjjajuuuuuuuboffffa ^pointer is here (all data before this is comitted to the image) Also notice how one of the "a"s change to a b. There are only 3 "a"s now t3: 4-ajjjjjjjajuuuuuuuboffffa ^pointer is here (all data before this is comitted to the image) The final image now reads "4-ajjjjjjjajuuuuuuuboffffa", while the true data is "3-ajjjjjjjajuuuuuuuboffffa" leading to a corrupt "database". Basically changes further down the blockchain could be reflected in the image, while important header and synchronization could already be committed. The out of date header information doesn't accurately reflect the structure of the blocks to come.

• Problem configuring php-fpm with nginx

  - by Nisanio

  First of all: I'm not an expert in configuring things. This is very new for me, so, my apologies in advance. At work we have a Centos server. The guy who worked here before installed nginx. We need to made a php site, so, obviously, I need to set up php and make it work with nginx. Making short a very long tale, I had to replace the nginx binary with a new one (because the older was compile without fast-cgi), and I had to recompile and install php (because the new version has fpm). Then I struggle with the config files, making this nginx.conf (not all the file) user php; location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; include fastcgi_params; } and uncomment some parameters in php-fpm (to much to detail here, but the important is that group and user are "php") I never could start the php-fpm with the instructions of the book sudo /usr/sbin/php-fpm start But after look at the net, I found this sudo /usr/local/sbin/php-fpm --fpm-config=/usr/local/etc/php-fpm.conf This worked (I think) I restarted nginx. But... nothings happens with php... My calls to php files (via firefox) doesn't even appear in the log (/opt/nginx/logs/error.log) I'm really, really exhausted and lost... Could anyone help me, pleaaase.... :( Thanks in advance

• How can I fix Office Sharepoint Search service?

  - by unknown (yahoo)

  For some reason, in operations server services, Office Sharepoint Search Service is MISSING! Which means I cant get Shared services working, which in turn I cannot get, and I do not think I have ever got Usage and reporting to see who is visiting my website, counter and with what OS/ browser ETC. I dont think I have ever seen this work in the 2 years trying with sharepoint. So in essense I have two problems, most important SEARCH, second usage reports. When trying to search, all i get is unknown error. Nothing is in my event viewer at all. I have tried http://www.cjvandyk.com/blog/Lists/Posts/Post.aspx?ID=96 , in the comments on that site, on other person reports search is missing entirely and is going to uninstall. Im tired of uninstall sharepoint and resinstalling to fix an odd off issue. I have things setup with Team foundation server that took forever to get work and reinstallation is not my solution. As for usage reporting, this is what microsoft responds to the " Both Windows SharePoint Services Usage logging and Office SharePoint Usage Processing must be enabled to view usage reports. Please contact your administrator to ensure that these services are enabled. " error I cannot do all the steps since SSP needs to be setup which i cant above.

• Using NginX and Apache alongside for both static and dynamic files

  - by faridv

  Background: I've searched a lot and found these useful threads about using of Apache or NginX for static or dynamic files. But they are old (mostly about 1 or 2 years ago) and I think both webservers, specifically Nginx has had important changes in performance and usage. So I think take another look on these issue cannot be that bad. Nginx (for static files) and Apache (for dynamic content)? nginx better than apache for dynamic content? [closed] Apache or NGINX for PHP? Nginx as reverse proxy to Apache with only dynamic content? My question: I have a PHP web application with lots of dynamic files and lots of static contents (videos, images etc.) and it's currently running on a CentOS 6 server and Apache 2.2 since 2 months ago. In past few days, number of our site visitors have gained so fast and I just thought if this number continues to increase with current ratio, we need to change many things (web server, application, etc.) to prevent failures. Because of hardware limitations that we are facing, I thought that it's best for us to start with web server. Should I start with something else? Should I try to increase performance of my PHP application and forget about web server for now? (even if gonna take a long time!) Because of huge usage of .htaccess files (for redirection, rewrites, etc.), I think it's gonna be painful to migrate to NginX as default web server or maybe only for dynamic files. Does this mean that I can't even use Nginx as reverse proxy? I'm not sure latest stable version of NginX and PHP-FPM have a better performance over my current Apache and my limitations (too many things) won't let me to give it a try. Which one is doing better currently? What will I lose by migrating to Nginx? To make it short, what should I do?

• Create a special folder within an outlook PST file

  - by Tony Dallimore

  Original question I have two problems caused by missing special folders. I added a second email address for which Outlook created a new PST file with an Inbox to which emails are successfully imported. But there is no Deleted Items folder. If I attempt to delete an unwanted email it is struck out. If move an email to a different PST file it is copied. I created a new PST file using Data File Management. This PST file has no Drafts folder. This is not important but I fail to see why I cannot have Drafts folder if I want. Any suggestions for solving these problems, particularly the first, gratefully received. Update Thanks to Ramhound and Dave Rook for their helpful responses to my original question. I assumed the problem of not have a Drafts folder in an Archive PST file and not having a Deleted Items folder associated with an Inbox were part of the same problem or I would not have mentioned the Drafts folder issue since I have an easy work-around. Perhaps my question should have been: How to I load emails from an IMAP account and be able to delete the spam?

• Setting up HTTPS across multiple servers

  - by JohnyD

  I'm looking to offer our online services over https and I'm having a couple of problems understanding how to accomplish this. To access our services you must pass through our ISA firewall to a Win2000 server running IIS6. About half our services are located here and the other half take you to a Win2003 server also running IIS6. So, in order to achieve this must each server have the proper certificate installed? ISA, IIS6_1 and IIS6_2? Is there a separate configuration that must be made to our ISA firewall? The other problem is with the CA and knowing how many certificates I need. It's important to note that the domain name for our services on IIS6_1 is www.domainname.com but the domain name on IIS6_2 is services.domainname.com. I believe that this will require me to purchase more than one certificate. It looks as though we will be going with Thawte's SSL123 as it's a good name and it's fast to get. Will I need to purchase 2 certificates (one for www that will be installed on our ISA firewall as well as IIS6_1, and one for services.domainname.com on IIS6_2)? Or will I need to purchase 3, the extra one being used on our firewall server? Another side question is about SAN's (subject alternative names). Is this basically adding sub-domains to your cert? So I could purchase one cert with 1 SAN for my www and services.? Thanks a lot for your help! Please let me know if I can provide any further information.

• Xen networking is inconsistent in multiple ways

  - by WildVelociraptor

  I've been running xen for a few weeks now on an Ubuntu 12.04 server. I've got 3 guests: a Windows Server 2003 guest, an Ubuntu guest, and a Windows 7 Guest. My Server 2003 guest seems to work fine; I can ping it from the network, the hostname resolves correctly, and it can see the internet. This guest is attached to xenbr0, and its IP is 10.100.1.21. My Win7 guest is what is driving me crazy. I use the same configuration script as a base, changing the important parts (hostname and boot disk, mainly). It installed correctly, and is currently running, but I am unable to ping this guest. It's hostname is "alexander", with an IP of 10.100.1.22. It is also using xenbr0. The guest can ping the firewall and various IP addressess, but seems unable to resolve hostnames. Now heres the weird part: when I use rdesktop (RDP client) from my laptop (not the xen host) to connect to alexander, it works just fine. It apparently resolves the hostname fine, and does the same with the IP address. So, can someone tell me why I can access this guest using RDP, but not using ping, nslookup, traceroute, etc? It's apparently invisible to all but RDP. Also, is it okay to use two guests on the same bridge, or do i need different ones for each guest? Thanks in advance for any help. Regards

• Data recovery on a corrupted 3TB disk

  - by Mark K Cowan

  Short version I probably need software to run a deep-scan recovery (ideally on Linux) to find files on NTFS filesystem. The file data is intact, but the references are no longer present. Analogous to recovering data from a "quick-formatted" partition. Hopefully there is a smarter way available than deep-scan, one which would recover filenames and possibly paths. Long version I have a 3TB disk containing a load of backups. Windows 7 SP1 refused to detect the disk when plugged in directly via SATA, so I put it on a USB/SATA adaptor which seemed to work at first. The SATA/USB adaptor probably does not support disks over 2.2TB though. Windows first asked me if I wanted to 'format' the disk, then later showed me most of the contents but some folder were inaccessible. I stupidly decided to run a CHKDSK on my backup disk, which made the folders accessible but also left them empty. I connected this disk via SATA to my main PC (Arch Linux). I tried: testdisk ntfsundelete ntfsfix --no-action (to look for diagnostically relevant faults, disk was "OK" though) to no avail as the files references in the tables had presumably been zeroed out by CHKDSK, rather than using a typical journal'd deletion). If it is useful at all, a majority of the files that I want to recover are JPEG, Photoshop PSD, and MPEG-3/MPEG-4/AVI/MKV files. If worst comes to worst, I'll just design my own sector scanner and use some simple heuristic-driven analysis to recover raw binary blocks of data from the disk which appears to match the structures of the above file types. I am unfamiliar with the exact workings of NTFS but used to be proficient at recovering FAT32 systems with just a hex-editor, so I can provide any useful diagnostic information if you let me know how to find it! My priorities in ascending order of importance for choosing the accepted answer: Restores directory structure Recovers many filenames in addition to the file data Is free / very cheap Runs on Linux Recovers a majority of file data The last point is the most important, but the more of the higher points you match the more rep you'll probably get :)

• What to do before connecting Ubuntu Server to the internet for the first time?

  - by CodeMonkey

  I just finished installing Ubuntu Server 12.10 on an Asus Eee PC 1000H (to be used as a home server/sandbox) from USB. I installed this software during installation: OpenSSH server LAMP server Samba file server Virtual Machine host I won't use 2, 3 or 4 for a while though. Can/should I turn these off somehow? I have turned home directory encryption on. Security updates are installed automatically. I have chosen a strong password for the single user. I have never plugged in the internet cable so far. Before doing so I'd like to ask: What can/should I do/install to increase security before connecting to the internet? Firewall? Fail2ban? Users/Passwords? Encryption? Enable/Disable functionality? etc. I'm sorry if you get this question a lot. I've searched around quite a while, but it still feels like I might overlook something important.
