  • Why You Should Learn HTML

    HTML stands for hyper text markup language. This is the coding that is used to create and design webpages. There are other codes, but they are not as essential that you learn them as you can still get by without knowing those codes. But if you are serious about making money online, then it is necessary that you learn HTML.

  • PHP-FPM and APC for shared hosting?

    - by Tiffany Walker
    We are looking into finding a way to get APC to only create one cache per account / site. This can be done with Fastcgi (last update 2006…) but with Fastcgid APC will have to create multiple caches for multiple processes run by the same account. To get around this problem, we have been looking into PHP-FPM PHP process manager allows multiple PHP processes to share a single APC cache. But from what I have read (I hope I'm wrong) , even if you create a pool per process, all sites accross all pools will share the same APC cache. This brings us back to the same problem as with shared Memcached: it's not secure ! On php-fpm's site I read that you can chroot php-fpm pools and define a specific UID and GID per pool… if this is the case then shouldn't APC have to use this user and not have access to other pools cache ? An article here (in 2011) suggests that you would need to run one process per pool creating multiple launchers on different ports and different config files with one pool per config file : http://groups.drupal.org/node/198168 Is this still neceessary ? If so what would be the impact of running say 800 processes of php-fpm ? Would it be mainly memory ? If so how can I work out what the memory impact would be ? I guess that it would be better to run 800 times php-fpm then to have accounts creating multiple APC caches for a single site ? If on average an account creates a 50MB cache and creates 3 caches per account that makes 150Mb per account which makes 120GB… However if each account uses on average only 50Mb that would make 40GB We will have at least 128GB of ram on our next server so 40GB is acceptable if running 800 x PHP-FPM does not create an overhead of more than 20GB ! What do you think is PHP-FPM the best way to go to provide secure APC cache on shared hosting with a server that has a decent amount of memory ? Or should I be looking at another system ? Thanks !

  • QoS for Cisco Router to Prioritize Voice and Interactive Traffic

    - by TJ Huffington
    I have a Cisco 891W NATing Voice and Data to the internet over a 10mbit/2mbit connection. Voice traffic gets degraded when I upload large files. Pings time out as well. I tried to configure a QoS policy but it's basically not doing anything. Voice traffic still degrades when upload bandwidth gets saturated. Here is my current configruation: class-map match-any QoS-Transactional match protocol ssh match protocol xwindows class-map match-any QoS-Voice match protocol rtp audio class-map match-any QoS-Bulk match protocol secure-nntp match protocol smtp match protocol tftp match protocol ftp class-map match-any QoS-Management match protocol snmp match protocol dns match protocol secure-imap class-map match-any QoS-Inter-Video match protocol rtp video class-map match-any QoS-Voice-Control match access-group name Voice-Control policy-map QoS-Priority-Output class QoS-Voice priority percent 25 set dscp ef class QoS-Inter-Video bandwidth remaining percent 10 set dscp af41 class QoS-Transactional bandwidth remaining percent 25 random-detect dscp-based set dscp af21 class QoS-Bulk bandwidth remaining percent 5 random-detect dscp-based set dscp af11 class QoS-Management bandwidth remaining percent 1 set dscp cs2 class QoS-Voice-Control priority percent 5 set dscp ef class class-default fair-queue interface FastEthernet8 bandwidth 1024 bandwidth receive 20480 ip address dhcp ip nat outside ip virtual-reassembly duplex auto speed auto auto discovery qos crypto map mymap max-reserved-bandwidth 80 service-policy output QoS-Priority-Output crypto map mymap 10 ipsec-isakmp set peer 1.2.3.4 default set transform-set ESP-3DES-SHA match address 110 qos pre-classify ! fa8 is my connection to the internet. Voice traffic goes over a VPN ("mymap") to the SIP server. That's why I specified "qos pre-classify" which I believe is the way to classify traffic over the VPN. However even when I ping a public IP while saturating upload bandwidth, the latency is exceptionally high. Is this configuration correct? Are there any suggestions that might make this work for my setup? Thanks in advance.

  • Gmail: security warning icon

    - by Notetaker
    Hello, I just enabled some Gmail Labs programs in my Gmail account, and then I noticed the orange triangle icon with an exclamation mark in it at the end of the address bar of my Google Chrome browser. Clicking on it brought forth a "Security Information' dialog box, with the following messages: "--mail.google.com The identity of website has been verified by Thawlte SGC CA. --Your connection to mail.google.com is encrypted with 128-bit encryption. However, this page includes other resources which are not secure. These resources can be viewed by others while in transit, and can be modified by an attacker to change the look or behavior of the page." I then logged into two of my other Gmail accounts, one of which has no Gmail Labs programs enabled, and the other with 1 program enabled quite some time ago, both with the same result as above (i.e., with the appearance of the orange triangle warning sign in the address bar). I don't remember seeing the orange triangle before, but I'm not sure if it has ever appeared or not. I have "Always use https" enabled for my Gmail accounts. My questions are: Is there a way to identify and remove these un-secure "resources"? (Could enabling Gmail Labs programs have brought these on?) Meanwhile, are my Gmail accounts compromised and unsafe to use? If so, what should I being doing about that now? After this problem is solved, would I need to reset the password to my Gmail accounts, and/or take any other measures to restore their security? Many thanks for answering my questions!

  • How to securely enable file sharing over PPTP on Windows 2008 Server

    - by Damage
    I have set up a Windows SBS 2003 domain (LAN) and a stand-alone Windows 2008 Server (web server) at another location (workgroup). I established PPTP VPN connection (SBS dials web server) over which users from LAN should be able to access web server. On web server I enabled TCP/IPv4 and File and Printer sharing protocol. It has a few external addresses (one of them is default) AND one local address (192.x.x.x) assigned to network adapter. Firewall allows port 445 for file sharing. There's the problem - I can not enable web server file shares to be visible to LAN users and ONLY to LAN users: From SBS I can access webserver but I cannot access webserver from LAN workstations (XP, Vista). I have had same configuration - I have just replaced old (web server) Windows 2003 server with 2008 so SBS settings are the same (static route, DNS etc.). How can I enable file sharing on web server for LAN workstations? Now I have opened File and printer sharing to the internet which is of course totaly unsecure. I tried to secure the tunnel so I moved RAS (VPN) connection (Network Center) on web server to "Private" profile and moved firewall port 445 to "Private" profile but suddenly file sharing does not work and I cannot telnet webserver on port 445. How can I secure file sharing so I do not have to open it to the internet?

  • Any Recommendations for a Web Based Large File Transfer System?

    - by Glen Richards
    I'm looking for a server software product that: Allows my users to share large files with: The general public securely to 1 or more people (notification via email, optionally with a token that gives them x period of time to download) Allows anyone in the general public to share files with my users. Perhaps by invitation. Has to be user friendly enough to allow my users to use this with out having to bug me as the admin. It needs to be a system that we can install on our own server (we don't want shared data sitting on anyone else's server) A web based solution. Using some kind or secure comms channel would be good too, eg, ssh Files to share could be over 1 GB. I found the question below. WebDav does not sound user friendly enough: http://serverfault.com/questions/86878/recommendations-for-a-secure-and-simple-dropbox-system I've done a lot of searching, but I can't get the search terms right. There are too many services that provide this, but I want something we can install on our own server. A last resort would be to roll my own. Any ideas appreciated. Glen EDIT Sorry Tom and Jeff but Glen specifically says that he's looking for a 'product' so given that I specialise in this field thought that my expertise in this area may have been of use to him. I don't see how him writing services is going to be easy for him to maintain going forward (large IT admin overhead) or simple for his users and the general public to work with.

  • Chroot jail of Nginx and php

    - by sqren
    I'm hosting multiple websites on one VPS, and want to chroot each website, eg. /chroot/website1 /chroot/website2 I'm using makejail, which is a highlevel tool, for creating the jails, and copying the libraries and dependencies. Easy peasy. Each website will need nginx, php and mysql. For php I'm using php5-fpm which actually supports chroot by configuration, however I'm not using this (maybe I should?) My question is which approach of the following three is the better: 1) Every website will have its own seperated instance of nginx, php and mysql. The downside is, that each webserver + php has to listen to a different port. I also need a "master" nginx web server in front of them, reverse proxying to the chrooted servers behind it. Probably most secure, but also most advanced. 2) I don't make any chroot jails manually. I setup one nginx web server, that proxies php requests to php-fpm, on different ports. I can have multiple php-fpm configurations each with is own chroot'ed folder. This is quite managable - however only php will be chrooted. Not the actual webserver. Is this secure enough. Also, I tried this option out, and it seems I will need to use TCP instead of sockets for connecting to MySQL. 3) You tell me ;) I'm quite new to chroot jailing, so please correct me if I'm wrong in my assumptions. I've been reading all the tutorials I could find, however, I find the market for chroot guides very scarce. Any help or inputs much appreciated!

  • NIS: which mechanism hides shadow.byname for unpriviledged users?

    - by Mark Salzer
    On some Linux box (SLES 11.1) which is a NIS client I can do as root: ypcat shadow.byname and get output, i.e. some lines with the encrypted passwords, amongst other information. On the same Linux box, if I run the same command as unpriviledged user, I get No such map shadow.byname. Reason: No such map in server's domain Now I am surprised. My good old knowlege says that shadow passwords in NIS are absurd because there is no access control or authentication in the protocol and thus every (unpriviledged) user can access the shadow map and thereby obtain the encrypted passwords. Obviously we have a different picture here. Unfortunately I don't have access to the NIS server to figure out what is happening. My only guess is that the NIS master gives the map only to clients conection from a priviledged port (1024), but this is only an uneducated guess. What mechanisms are there in current NIS implementations to lead to a behavior like the above? How "secure" are they? Can the be circumvented easily? Or are shadow passwords in NIS as secure as the good old shadow files?

  • Firefox and Chrome keeps forcing HTTPS on Rails app using nginx/Passenger

    - by Steve
    I've got a really weird problem here where every time I try to browse my Rails app in non-SSL mode Chrome (v16) and Firefox (v7) keeps forcing my website to be served in HTTPS. My Rails application is deployed on a Ubuntu VPS using Capistrano, nginx, Passenger and a wildcard SSL certificate. I have set these parameters for port 80 in the nginx.conf: passenger_set_cgi_param HTTP_X_FORWARDED_PROTO http; passenger_set_cgi_param HTTPS off; The long version of my nginx.conf can be found here: https://gist.github.com/2eab42666c609b015bff The ssl-redirect.include file contains: rewrite ^/sign_up https://$host$request_uri? permanent ; rewrite ^/login https://$host$request_uri? permanent ; rewrite ^/settings/password https://$host$request_uri? permanent ; It is to make sure those three pages use HTTPS when coming from non-SSL request. My production.rb file contains this line: # Enable HTTP and HTTPS in parallel config.middleware.insert_before Rack::Lock, Rack::SSL, :exclude => proc { |env| env['HTTPS'] != 'on' } I have tried redirecting to HTTP via nginx rewrites, Ruby on Rails redirects and also used Rails view url using HTTP protocol. My application.rb file contains this methods used in a before_filter hook: def force_http if Rails.env.production? if request.ssl? redirect_to :protocol => 'http', :status => :moved_permanently end end end Every time I try to redirect to HTTP non-SSL the browser attempts to redirect it back to HTTPS causing an infinite redirect loop. Safari, however, works just fine. Even when I've disabled serving SSL in nginx the browsers still try to connect to the site using HTTPS. I should also mention that when I pushed my app on to Heroku, the Rails redirect work just fine for all browsers. The reason why I want to use non-SSL is that my homepage contains non-secure dynamic embedded objects and a non-secure CDN and I want to prevent security warnings. I don't know what is causing the browser to keep forcing HTTPS requests.

  • Cannot connect on TFS 2012 server through SSL with invalid certificate

    - by DaveWut
    I saw the problem on some forums and even here, but not as specific as mine. So here's the thing, So I've configured a TFS 2012 server, on one of my personnel server at home, and now, I'm trying to make it available through the internet, with the help of apache2 on a different UNIX based, physical server. The thing is working perfectly, I don't have any problem accessing the address https://tfs.something.com/tfs through my browser. The address can be pinged and I do have access to the TFS control panel through it. How does it work? Well, with apache2 you can set a virtual host and set up the ProxyPass and ProxyPassReserver setting, so the traffic can externally comes from a secure SSL connection, through a specified domain or sub-domain, but it can be locally redirect on a clear http session on a different port. This is my current setup. As I already said, I can access the web interface, but when I'm trying to connect with Visual Studio 2012, it can't be done. Here's the error I receive: http://i.imgur.com/TLQIn.png The technical information tells me: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. My SSL certificate is invalid and was automatically generated on my UNIX server. Even if I try to add it in the Trusted Root Certification Authorities either on my TFS server or on my local workstation, it doesn't work. I still receive the same error. Is there's a way to completely ignore certificate validation? If not, what's have I done? I mean, I've added the certificate in the trusted root certificates, it should works as mentioned on some forums... If you need more information, please ask me, I'll be pleased to provide you more.

  • Way to speed up load-balanced ssl using nginx?

    - by paulnsorensen
    So the setup for our website is 4 nodes running rails 3 and nginx 1 that all use the same GoDaddy certificate. Because we are a paid site, we have to maintain PCI-DSS compliance and thus have to use the more expensive SSL ciphers -- also we force SSL using Rack. I've recently switched over to Linode's NodeBalancer (which I've read is an HACluster), and we're not getting the performance we'd ideally like. From what I've read, it looks like terminating the SSL on the nodes using the high cipher is what is causing the poor performance, but I'd like to be thorough. Is there anything I can do? I've read about other ways to terminate the SSL before the NodeBalancer (like using stud), but I don't know enough about these solutions. We certainly don't want to do anything experimental or anything that has a single point of failure. If there really isn't anything I can do to speed up the SSL handshake, my alternative would be to support certain pages on Rails using a secure and insecure subdomain. I've found a few guides that walk through that, but my resulting question is in this situation, would it be better to have nginx handle forcing ssl on the secure subdomain instead of rails? Thanks!

  • Trying to use a SmartHost with my Exchange 2010 server

    - by Pure.Krome
    Hi folks, I'm trying to use a SmartHost with my Exchange 2010 Server. SmartHost details: Secure SMTPS: securemail.internode.on.net 465 <-- Note: that's port 465 Configure your existing SMTP settings (in your email program) to: use authentication (enter your Internode username and password, enter your username as [email protected]). enable SSL for sending email (SMTPS). So I've added the smart host details to my Org Config -> Hub Transport. I then used PowerShell to add the port:- Set-SendConnector "securemail.internode.on.net" -port 465 I've then added my username/password (as suggested above) to the SmartHost as Basic Authentication (with no TLS). Then I try sending an email and I get the following error message :- 451 4.4.0 Primary target IP address responded with: "421 4.4.2 Connection dropped due to ConnectionReset." So i'm not sure how to continue. I also tried ticking the TLS box but stll I get the same error. If i don't use SMTPS (secure SMTP, on port 465) and use basic SMTP on port 25 with no Authentication, email gets sent. Any ideas? EDIT: Btw, I can telnet to that server on port 465 from my mail server .. just to make sure i'm not getting firewall'd, etc.

  • Installation of Active Directory on separate VM from DNS does not entierly work - not sure why

    - by René Kåbis
    Not sure what I am doing wrong here. I have a moderately midrange server (16 cores, 2Ghz, 32GB ECC REG RAM, 6TB storage, nothing too extreme) where I am running Hyper-V (Server 2012 R2 Enterprise) in order to provision virtual machines. So why an AD separate from DNS? I want redundancy. I want to be able to move VMs and back them up individually and not have too many services on any one VM. I have already provisioned a VM with DNS, and have set it up right -- essentially, I have: Set up Static IP’s for everyone involved. Installed the DNS service on the DNS VM. Created a forward lookup zone and a reverse lookup zone (primary zone) xyz.ca Configured the zones to use nonsecure and secure dynamic updates (i will change this to secure later after the domain controller is online). Created a A record for the DC in the forward lookup zone (and a reverse ptr) Changed DC’s DNS server (network settings) to the new DNS server. Checked that I can ping the dns server from the new DC by hostname. When I went ahead and did a DCpromo on the DC, and un-cheked the “install DNS” option, everything seemed to go well (no error messages), but I saw no changes on the DNS server whatsoever (no additional settings). Plus, the DNS server seems to be unable to join the domain, as it claims that the domain is not discoverable. As a final note, I do run Symantec Endpoint Protection, which includes a firewall and most settings set as default. I have not yet tried turning this off, but my experience has been that if a service would open up a port on a Windows firewall, it would do the same through Symantec. There is pretty tight integration these days with corporate-class AV and Windows. I have a template vhdx fully set up (just short of any special roles and features) that I can use to replace the current AD VM with, so doing this all over again is not too much skin off of my nose.

  • What folders to encrypt with EFS on Windows 7 laptop?

    - by Joe Schmoe
    Since I've been using my laptop more as a laptop recently (carrying it around) I am now evaluating my strategy to protect confidential information in case it is stolen. Keep in mind that my laptop is 6 years old (Lenovo T61 with 8 GB or RAM, 2GHz dual core CPU). It runs Windows 7 fine but it is no speedy demon. It doesn't support AES instruction set. I've been using TrueCrypt volume mounted on demand for really important stuff like financial statements forever. Nothing else is encrypted. I just finished my evaluation of EFS, Bitlocker and took a closer look at TrueCrypt again. I've come to conclusion that boot partition encryption via Bitlocker or TrueCrypt is not worth the hassle. I may decide in the future to use Bitlocker or TrueCrypt to encrypt one of the data volumes but at this point I intend to use EFS to encrypt parts of my hard drive that contain data that I wouldn't want exposed. The purpose of this post is to get your feedback about what folders should be encrypted from the general point of view (of course everyone will have something specific in addition) Here is what I thought of so far (will update if I think of something else): 1) AppData\Local\Microsoft\Outlook - Outlook files 2) AppData\Local\Thunderbird\Profiles and AppData\Roaming\Thunderbird\Profiles- Thunderbird profiles, not sure yet where exactly data is stored. 3) AppData\Roaming\Mozilla\Firefox\Profiles\djdsakdjh.default\bookmarkbackups - Firefox bookmark backup. Is there a separate location for "main" Firefox bookmark file? I haven't figured it out yet. 4) Bookmarks for Chrome (don't know where it's bookmarks are) and Internet Explorer ($Username\Favorites) - I don't really use them but why not to secure that as well. 5) Downloads\, My Documents\ and My Pictures\ folders I don't think I need to encrypt, say, latest service pack for Visual Studio. So I will probably create subfolder called "Secure" in all of these folders and set it to "Encrypted". Anything sensitive I will save in this folder. Any other suggestions? Again, this is from the point of view of your "regular office user".

  • Forcing a particular SSL protocol for an nginx proxying server

    - by vitch
    I am developing an application against a remote https web service. While developing I need to proxy requests from my local development server (running nginx on ubuntu) to the remote https web server. Here is the relevant nginx config: server { server_name project.dev; listen 443; ssl on; ssl_certificate /etc/nginx/ssl/server.crt; ssl_certificate_key /etc/nginx/ssl/server.key; location / { proxy_pass https://remote.server.com; proxy_set_header Host remote.server.com; proxy_redirect off; } } The problem is that the remote HTTPS server can only accept connections over SSLv3 as can be seen from the following openssl calls. Not working: $ openssl s_client -connect remote.server.com:443 CONNECTED(00000003) 139849073899168:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:177: --- no peer certificate available --- No client certificate CA names sent --- SSL handshake has read 0 bytes and written 226 bytes --- New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE --- Working: $ openssl s_client -connect remote.server.com:443 -ssl3 CONNECTED(00000003) <snip> --- SSL handshake has read 1562 bytes and written 359 bytes --- New, TLSv1/SSLv3, Cipher is RC4-SHA Server public key is 1024 bit Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE SSL-Session: Protocol : SSLv3 Cipher : RC4-SHA <snip> With the current setup my nginx proxy gives a 502 Bad Gateway when I connect to it in a browser. Enabling debug in the error log I can see the message: [info] 1451#0: *16 peer closed connection in SSL handshake while SSL handshaking to upstream. I tried adding ssl_protocols SSLv3; to the nginx configuration but that didn't help. Does anyone know how I can set this up to work correctly?

  • How to have SSL on Amazon Elastic Load Balancer with a Gunicorn EC2 server?

    - by Riegie Godwin
    I'm a self taught back end engineer so I'm learning all of this stuff as I go along. For the longest time, I've been using basic authentication for my users. Many developers are advising against this approach since each request will contain the username & password in clear text. Anyone with the right skills can sniff on the connection between my iOS application and my Django/Gunicorn Server and obtain their password. I wouldn't want to put my user's credentials at risk so I would like to implement a more secure way of authentication. SSL seems to be the most viable option. My server doesn't serve any static content or anything crazy of that sort. All the server does is send and receive "json" responses from and to my iOS application. Here is my current topology. iOS application ------ Amazon Elastic Load Balancer ------- EC2 Instances running HTTP Gunicorn. Gunicorn runs on port 8000. I have a CNAME record from GoDaddy for the Amazon Elastic Load Balancer DNS. So instead of using the long DNS to make requests, I just use server.example.com. To interact with my servers I send and receive requests to server.example.com:8000/ This setup works and has been solid. However I need to have a more secure way. I would like to setup SSL between my iOS application and my Elastic Load Balancer. How can I go about doing this? Since I am only sending json responses to my application, do I really need to buy a certificate from a CA or can I create my own? (since browsers will not be interacting with my servers. My servers are only designed to send json responses to my iOS application).

  • No discs found when trying to install Windows 8 with UEFI

    - by Sahas Katta
    I have a Vizio Notebook (CN15-A5). It came pre-installed with Windows 8 x64 and is taking advantage of UEFI out of the box. The BIOS (APTOS AMI) is in Secure Boot mode with the OS selected as "Windows 8". I removed the stock HDD that came with the machine and put my own SSD into it. I created a Windows 8 Pro x64 installation disc on a 4GB USB flash drive formated as FAT32 since its apparently required for UEFI. When I boot from the USB Win8 installation disc, I get suck when I reach the "Custom: Install Windows only" section. Normally you would see a list of available discs and their partitions, however my entire list is blank. If I head back to the BIOS and disable Secure Boot and set the OS to "Other OS" and attempt again, I am able to see the list of available discs in the system and can install a copy of Windows 8. Unfortunately, doing it in this method results in an installation with a traditional 350 MB partition + OS partition instead of 4 partitions which is normal for a UEFI setup. Has anyone run into this problem? I've tried loading defaults in the BIOS and attempting to install via every combination with no luck. Any help would be appreciated.

  • Any Recommendations for a Web Based Large File Transfer System?

    - by Glen Richards
    I'm looking for a server software product that: Allows my users to share large files with: The general public securely to 1 or more people (notification via email, optionally with a token that gives them x period of time to download) Allows anyone in the general public to share files with my users. Perhaps by invitation. Has to be user friendly enough to allow my users to use this with out having to bug me as the admin. It needs to be a system that we can install on our own server (we don't want shared data sitting on anyone else's server) A web based solution. Using some kind or secure comms channel would be good too, eg, ssh Files to share could be over 1 GB. I found the question below. WebDav does not sound user friendly enough: http://serverfault.com/questions/86878/recommendations-for-a-secure-and-simple-dropbox-system I've done a lot of searching, but I can't get the search terms right. There are too many services that provide this, but I want something we can install on our own server. A last resort would be to roll my own. Any ideas appreciated. Glen EDIT Sorry Tom and Jeff but Glen specifically says that he's looking for a 'product' so given that I specialise in this field thought that my expertise in this area may have been of use to him. I don't see how him writing services is going to be easy for him to maintain going forward (large IT admin overhead) or simple for his users and the general public to work with.

  • Fully FOSS EMail solution

    - by Ravi
    I am looking at various FOSS options to build a robust EMail solution for a government funded university. Commercial options are to be chosen only in the worst case scenario. Here are the requirements: Approx 1000-1500 users - Postfix or Exim? (Sendmail is out;-)) Mailing lists for different groups/Need web based archive - Mailman? Sympa? Centralised identity store - OpenLDAP? Fedora 389DS? Secure IMAP only - no POP3 required - Courier? Dovecot? Cyrus?? Anti Spam - SpamAssasin? what else? Calendaring - ?? webmail - good to have, not mandatory - needs to be very secure...so squirrelmail is out;-)? Other questions: What mailbox storage format to use? where to store? database/file system? Simple and effective HA options? Is there a web proxy equivalent to squid in the mail server world? software load balancers?CARP? Monitoring and alert? Backup? The govt wants to stimulate the local economy by buying hardware locally from whitebox vendors. Also local consultants and university students will do the integration. We looked at out-of-the-box integrated solutions like Axigen, Zimbra and GMail but each was ruled out in favour of a DIY approach in the hopes of full control over the data and avoiding vendor lockin - which i though was a smart thing to do. I wish more provincial governments in the developing world think of these sort of initiatives As for OS - Debian, FreeBSD would be first preference. Commercial OS's need not apply. CentOS as second tier option...

  • VSFTPD - FTP over TLS - Upload stops after exactly 82k?

    - by Redsandro
    I installed a VSFTP daemon on a CentOS server, using a RSA certificate for logging in using explicit TLS. Now, I cannot upload more than 82k. With files under that limit, there is no problem. The FTP works like a charm. But as soon as a file reaches 82k with FileZilla (81,952 bytes to be exact), the transfer will stop, and the FTP client hangs until time out is reached. FTP client console: 15:10:21 Command: STOR jquery-1.7.2.min.js 15:10:21 Response: 150 Ok to send data. 15:11:21 Error: Connection timed out 15:11:21 Error: File transfer failed after transferring 82 KB in 60 seconds /var/log/vsftpd.log FTP command: Client "x.x.x.x", "STOR jquery-1.7.2.min.js" FTP response: Client "x.x.x.x", "150 Ok to send data." OK UPLOAD: Client "x.x.x.x", "jquery-1.7.2.min.js", 81952 bytes, 1.32Kbyte/sec FTP response: Client "x.x.x.x", "226 File receive OK." // NOT okay, file is bigger // No mention of error here I cannot find relevant info about this problem, apart from a possible problem with trans_chunk_size (not mentioned in default config), but I tried different sizes and it has no impact on the problem. trans_chunk_size=4096 trans_chunk_size=8192 trans_chunk_size=9999 Ofcourse, after every configuration change, I restarted the server: /etc/init.d/vsftpd restart What else can cause this? It's not the latest version, but it's the latest update within the repositories that has been deemed fit for enterprise usage: Package info: $ yum info vsftpd Loaded plugins: fastestmirror Installed Packages Name : vsftpd Arch : x86_64 Version : 2.0.5 Release : 24.el5_8.1 Size : 286 k Repo : installed Summary : vsftpd - Very Secure Ftp Daemon URL : http://vsftpd.beasts.org/ License : GPL Description: vsftpd is a Very Secure FTP daemon. It was written completely from scratch.
