  • Determine from where is "sh" being run under apache www-data user using using PF or NETSTAT

    - by Eugene van der Merwe
    I am working with a compromised Ubuntu 8.04 Plesk 9.5.4 server. It seems that a script on the server is continuously doing reverse lookups to random IPs on the Internet. I first spotted it during by using top and then noticed flashes of this coming up continuously: sh -c host -W 1 '198.204.241.10' I wrote a this script to interrogate ps every 1 second to see how frequently this script happens: #!/bin/bash while : do ps -ef | egrep -i "sh -c host" sleep 1 done The results are that this script runs often, every few seconds: www-data 17762 8332 1 10:07 ? 00:00:00 sh -c host -W 1 '59.58.139.134' www-data 17772 8332 1 10:07 ? 00:00:00 sh -c host -W 1 '59.58.139.134' www-data 17879 17869 0 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' www-data 17879 17869 1 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' www-data 17879 17869 0 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' root 18031 17756 0 10:07 pts/2 00:00:00 egrep -i sh -c host www-data 18078 16704 0 10:07 ? 00:00:00 sh -c host -W 1 '59.58.139.134' www-data 18125 17996 0 10:07 ? 00:00:00 sh -c host -W 1 '91.124.51.65' root 18131 17756 0 10:07 pts/2 00:00:00 egrep -i sh -c host www-data 18137 17869 0 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' www-data 18137 17869 1 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' My theory is if I can see who is launching the sh process or form where it's launched I can isolate the problem further. Can somebody please guide me using netstat or ps to identify from where sh is being run? I might get many suggestions that the OS is out of date and so the Plesk, but please bear in mind there are some very concrete reasons why this server is running legacy software. My question is aimed at a advanced Linux systems administrators who have in depth experience with security compromises and using netstat and ps to get to the bottom of it.

  • Access an external SSH server through a restrictive proxy [on hold]

    - by Cyrille
    I'm a software developer. I wish to access my computer at home through SSH. For example, I sometime need to access my personal projects source code to check how I handled specific problems. Unfortunately, I currently work under an over-restrictive and anti-productive proxy that waste a hell of a lot of everyone's time (We often have to visit websites from our smartphones or use a web proxy to check very legitimates websites for answers, and don't get me started on other "security" overkill features we have to cope with...). Well, back to the subject, I can access my home computer from my phone (SSH, port 22 and 80 both redirected by router on port 22). It works, but it's quite uncomfortable. From my office computer, this is what I tried so far: export http_proxy=http://user:pass@proxyip:8080 echo "user:pass" > ~/.corkscrew-auth echo "ProxyCommand corkscrew proxyip 8080 %h %p /home/me/.corkscrew-auth" > ~/.ssh/config ssh 82.23.34.56 -l me -p 80 Proxy could not open connnection to 82.23.34.56: Forbidden ssh_exchange_identification: Connection closed by remote host (same without -p 80) Without corkscrew: ssh: connect to host 82.23.34.56 port 80: Connection timed out ssh: connect to host 82.23.34.56 port 22: Connection timed out Any other idea ?

  • Automatically update SVN repository on another server

    - by Mikey C
    We have 2 Ubuntu web servers, one of which is our staging server (Staging) and the other is our live server (Live). Staging has our Subversion repository, as well as the latest version of our sites on it. Because the SVN server is running on Staging, I've added post-commit hook scripts so that the staging server automatically has the latest code. Easy. However, I'd like one of the repositories on Live to also stay updated. This is a repository of images, PDFs and suchlike. When a team member commits to this, I'd like it to automatically update on the live servers so it can be used in mailings, content managed pages etc. I'd add something to the post-commit to SSH across and update, but for security, we can only SSH from one server to another as user 'commandLine', whereas the 'www-data' user runs the post-commit. I'd rather not run a cron on Live to update every 5 minutes, but I can't see another way of doing it without altering all our user permissions. Any ideas?

  • Server format & Reinstall while keeping Server & domain ID

    - by Chris
    Hi Everyone, I want to reinstall my 2008 R2 server from scratch, due to multiple Active Dir issues. I have only 1 server running AD and a spare machine to use if necessary. Is there a way to save just the user accounts and the domain SID, so that I can start with a clean server that uses the same name as before? I can reassign file security, but I do not want to have to rejoin all the users to a new domain. Also all users are mapped to folders on the server. What I hope to do is a clean install of the server without having to mess with the users machines. can someone please tell me the procedure to accomplish this? any help appreciated! Thanks guys, but I could be here all day telling you every error I am getting. can we please keep this to the question of how to do a reinstall and keep the same SID? I just want to start over without having to rejoin all the clients to a new domain. Is there such a tool that can backup the Server SID and the AD domain name so that I could restore them, without restoring any other data? I might not be using the correct terminology here, but hopefully you understand what I am asking. Thanks

  • Cannot make bind9 forward DNS query to subdomain unless recursive enabled

    - by PP.
    I am trying to develop my own dynamic DNS. I'm running my own custom DNS for the subdomain on port 5353. ASCII diagram: INET --->:53 Bind 9 --->:5353 node.js | V zone_files I have example.com. The node.js DNS is for dyn.example.com. In my /etc/bind/named.conf.local I have: zone "example.com" { type master; file "/etc/bind/db.com.example"; allow-transfer { zonetxfrsafe; }; }; zone "dyn.example.com" IN { # DYNAMIC type forward; forwarders { 127.0.0.1 port 5353; }; forward only; }; I've even gone so far as to add a NS in my example.com zone file: $TTL 86400 @ IN SOA ns.example.com. hostmaster.example.com. ( 2013070104 ; Serial 7200 ; Refresh 1200 ; Retry 2419200 ; Expire 86400 ) ; Negative Cache TTL ; NS ns ; inet of our nameserver ns A 1.2.3.4 ; NS record for subdomain dyn NS ns When I attempt to get a record from the subdomain server it doesn't get forwarded: dig @127.0.0.1 test.dyn.example.com However if I turn recursive on in /etc/bind/named.conf.options: options { recursion yes; } .. then I CAN see the request going to the subdomain server. But I don't want recursion yes; in my Bind configuration as it is poor security practice (and allows all-and-sundry requests that are not related to my managed zones). How does one forward (proxy) zone queries for just one zone? Or do I give up on Bind altogether and find a DNS server that can actually forward specific queries?

  • Permissions Issue with Files Generated by PerfMon

    - by SvrGuy
    We are trying to implement some data logging to CSV files using a Data Collector Set in PerfMon (on a windows Server 2008R2 system). The issue we are running into is that we (seemingly) can't control the permissions being set on the log files created by perfmon. What we want is for the log files created by perfmon to have Everyone:F permissions (Full Control for Everyone). So, we have a directory structure setup where all logs go into a folder: c:\vms\PerfMonLogs\%MACHINENAME% (e.g. c:\vms\PerfMonLogs\EvaluationG2) In the above example, c:\vms\PerfMonLogs\EvaluationG2 has permissions Everyone:F (below is the icacls for this directory) EVALUATIONG2/ Everyone:(OI)(CI)(F) NT AUTHORITY\SYSTEM:(OI)(CI)(F) BUILTIN\Administrators:(OI)(CI)(F) BUILTIN\Performance Log Users:(OI)(R) When the data collector set runs, it creates new sub folders and files within c:\vms\PerfMonLogs\EvaluationG2, e.g. (C:\vms\PerfMonLogs\EVALUATIONG2\M11d26y2012N3) Each of these directories and files has the following permissions: M11d26y2012N3 NT AUTHORITY\SYSTEM:(OI)(CI)(F) BUILTIN\Administrators:(OI)(CI)(F) BUILTIN\Performance Log Users:(OI)(R) So these new folders and not simply inheriting permissions from the parent folder (don't know why). Now, we tried adding Everyone:F using the security tab on the collector set (No dice). Any ideas? How do we control the permissions on the log files generated by perfmon data collector set?

  • Euro character messed up during FTP transfer

    - by djechelon
    My customer is using a very outdated ecommerce management system on my hosting service. For that product, no support is being provided anymore by the vendor. Brief explanation: the shop website, that claims to run under LAMP stack, is built by an old Visual Basic Windows application running on MS Access. The user constructs the shop, defines the HTML template, adds products and categories, etc. Then the VB exe builds the PHP pages (one for each template page) and the SQL script to run on MySQL. It also uploads everything via FTP and runs the installation/upgrade script on its own. The problem Browsing the website, many products' descriptions are cut before the euro sign. For example, what was supposed to be "Product price €1000" becomes "Product price" The analysis MySQL contains a cutted description until the € sign, so it's not PHP fault The Access databases contain full description with € sign, so it's not fault of the webmaster writing bad description or eDisplay cutting them The SQL that will run once the site gets uploaded, stored on my local machine before upload, contains the € sign The same script, after being FTPed by eDisplay and opened with nano from SSH, shows the € sign messed up like this: ^À vsftpd log reports (obfuscated for privacy) Sat Dec 15 11:16:57 2012 22 xxx.xxx.128.13 1112727 /srv/www/domains/xxxxxx.it/htdocs/db.sql b _ i r xxxxxxx ftp 0 * c which seems to be a binary transfer (and also a huge security vulnerability because you can download the whole database from unauthenticated HTTP) The eDisplay internal FTP client provides no option for ascii/binary transfer modes [Add] Trying to manually upload the SQL file via SFTP shows messing up euro [Add2] Trying to manually upload using Xftp client with explicit ASCII mode doesn't fix too It looks like the file gets uploaded as binary. Perhaps on the customer's previous host it all worked fine because that was a Windows host. The server It's an Azure virtual machine running openSUSE 12.2 with both vsftpd and openSSH The question Without asking the customer to manually upload files using FileZilla or replacing € with &euro;, because he refuses, what can I do on server side to prevent vsftpd to screw up euro sign?

  • How to recover Windows Password without reinstalling if you forgot Windows password?

    - by user38908
    Usually, we can recover Windows admin password in two traditional ways. The first is to change Windows password with another admin account; the second is to recover the previous password with the windows password reset disk that had been created before you forgot the password. Take Windows XP for example, 1 At the Windows XP login prompt when the password is entered incorrectly click the reset button in the login failed window. 2 Insert the password reset diskette into the computer and click Next. 3 If the correct diskette Windows XP will open a window prompting for the new password you wish to use. However, we offen ignore the important of security until we have been locked out of computer. Fortunately, there is still the last way that can unlock your computer without reinstalling - erase Windows password with Windows password reset CD, which can recover admin password for Windows 7/XP/Vista/NT/2000/2003.... Take Windows Password unlocker for example, followings are the steps to create the reset CD 1.Download Windows Password Unlocker from Password Unlocker Official site 2.Decompress the Windows password unlocker and note that there is an .ISO image file. Burn the image file onto an blank CD with the burner freely supported by Password Unlocker. 3.Insert the newly created CD into the locked computer and re-boot it from the CD drive. 4.After launched the CD, a window pop up with all your account names(if you have several accounts) select one of the accounts that you have forgotten its password to reset it. Just one press, this software can remove Windows password instantly.

  • Why does the Mac OS X firewall dialog recurringly pop-up and disappear by itself (without letting me

    - by Chris W. Rea
    From time to time, I'll be on my Macbook using a program that accesses the network – whether Firefox, or Sony's Reader Library – really, it seems like it could happen with any program that accesses the network – and for no reason that I can discern so far (that is, it happens intermittently) the OS X firewall dialog pops up to ask me the question: Except it doesn't actually let me click anything before it disappears! That is: the dialog pops up, ... then goes away by itself a second later, then pops up again, ... then goes away by itself a second later, etc. It happens a few times before stopping. It wouldn't be so maddening to be interrupted if I could just be allowed to click "Allow" and make the darn thing go away for good. In Security preferences I have the firewall turned "On", and I would like to keep it that way. Has anybody seen this problem, found the source, and figured out a solution or workaround? Thank you.

  • How to configure iptables to use apt-get in a server?

    - by segaco
    I'm starting using iptables (newbie) to protect a linux server (specifically Debian 5.0). Before I configure the iptables settings, I can use apt-get without a problem. But after I configure the iptables, the apt-get stop working. For example I use this script in iptables: #!/bin/sh IPT=/sbin/iptables ## FLUSH $IPT -F $IPT -X $IPT -t nat -F $IPT -t nat -X $IPT -t mangle -F $IPT -t mangle -X $IPT -P INPUT DROP $IPT -P OUTPUT DROP $IPT -P FORWARD DROP $IPT -A INPUT -i lo -j ACCEPT $IPT -A OUTPUT -o lo -j ACCEPT $IPT -A INPUT -p tcp --dport 22 -j ACCEPT $IPT -A OUTPUT -p tcp --sport 22 -j ACCEPT $IPT -A INPUT -p tcp --dport 80 -j ACCEPT $IPT -A OUTPUT -p tcp --sport 80 -j ACCEPT $IPT -A INPUT -p tcp --dport 443 -j ACCEPT $IPT -A OUTPUT -p tcp --sport 443 -j ACCEPT # Allow FTP connections @ port 21 $IPT -A INPUT -p tcp --sport 21 -m state --state ESTABLISHED -j ACCEPT $IPT -A OUTPUT -p tcp --dport 21 -m state --state NEW,ESTABLISHED -j ACCEPT # Allow Active FTP Connections $IPT -A INPUT -p tcp --sport 20 -m state --state ESTABLISHED,RELATED -j ACCEPT $IPT -A OUTPUT -p tcp --dport 20 -m state --state ESTABLISHED -j ACCEPT # Allow Passive FTP Connections $IPT -A INPUT -p tcp --sport 1024: --dport 1024: -m state --state ESTABLISHED -j ACCEPT $IPT -A OUTPUT -p tcp --sport 1024: --dport 1024: -m state --state ESTABLISHED,RELATED -j ACCEPT #DNS $IPT -A OUTPUT -p udp --dport 53 --sport 1024:65535 -j ACCEPT $IPT -A INPUT -p tcp --dport 1:1024 $IPT -A INPUT -p udp --dport 1:1024 $IPT -A INPUT -p tcp --dport 3306 -j DROP $IPT -A INPUT -p tcp --dport 10000 -j DROP $IPT -A INPUT -p udp --dport 10000 -j DROP then when I run apt-get I obtain: core:~# apt-get update 0% [Connecting to ftp.us.debian.org] [Connecting to security.debian.org] [Conne and it stalls.

  • MSMQ on Win2008 R2 won't receive messages from older clients

    - by Graffen
    I'm battling a really weird problem here. I have a Windows 2008 R2 server with Message Queueing installed. On another machine, running Windows 2003 is a service that is set up to send messages to a public queue on the 2008 server. However, messages never show up on the server. I've written a small console app that just sends a "Hello World" message to a test queue on the 2008 machine. Running this app on XP or 2003 results in absolutely nothing. However, when I try running the app on my Windows 7 machine, a message is delivered just fine. I've been through all sorts of security settings, disabled firewalls on all machines etc. The event log shows nothing of interest, and no exceptions are being thrown on the clients. Running a packet sniffer (WireShark) on the server reveals only a little. When trying to send a message from XP or 2003 I only see an ICMP error "Port Unreachable" on port 3527 (which I gather is an MQPing packet?). After that, silence. Wireshark shows a nice little stream of packets when I try from my Win7 client (as expected - messages get delivered just fine from Win7). I've enabled MSMQ End2End logging on the server, but only entries from the messages sent from my Win7 machine are appearing in the log. So somehow it seems that messages are being dropped silently somewhere along the route from XP or 2003 to my 2008 server. Does anyone have any clues as to what might be causing this mysterious behaviour? -- Jesper

  • Thunderbird 15.0.1 cannot use Exchange 2003 SMTP

    - by speedreeder
    I'm having the strangest time getting a Thunderbird email client to connect to my Exchange 2003 server. I got the incoming IMAP account set up no problem, and I can receive mail. However sending mail will not work no matter what SMTP settings I enter. After checking the server, the proper settings should be port 25 with no authentication or connection security, which I have entered. I can ping the hostname of the server from the client machine in question. The Thunderbird error message I get is: "Sending of message failed. The message could not be sent because the connection to SMTP server -hostname omitted- was lost in the middle of the transaction." So I went to the server and double checked the settings for Exchange's SMTP stuff. I have it correct. I tried to telnet (on the server) to localhost 25. It appears to connect and then disconnect immediately, no message, no nothing. When I telnet to other ports (POP-110 for example) I get proper connection messages and a stable connection. There are no firewalls on either the client or the server. There's a firewall on the network but LAN-LAN traffic is unrestricted. I can reproduce the Thunderbird error on a second client, and I can't get any client to be able to telnet in. Anyone have any ideas?

  • What Logs / Process Stats to monitor on a Ubuntu FTP server?

    - by Adam Salkin
    I am administering a server with Ubuntu Server which is running pureFTP. So far all is well, but I would like to know what I should be monitoring so that I can spot any potential stability and security issues. I'm not looking for sophisticated software, more an idea of what logs and process statistics are most useful for checking on the health of the system. I'm thinking that I can look at various parameters output from the "ps" command and compare to see if I have things like memory leaks. But I would like to know what experienced admins do. Also, how do I do a disk check so that when I reboot, I don't get a message saying something like "disk not checked for x days, forcing check" which delays the reboot? I assume there is command that I can run as a cron job late at night. How often should it be run? What things should I be looking at to spot intrusion attempts? The only shell access is SSH on a non-standard port through UFW firewall, and I regularly do a grep on auth.log for "Fail" or "Invalid". Is there anything else I should look at? I was logging the firewall (UFW) but I have very few open ports (FTP and SSH on a non standard port) so looking at lists of IP's that have been blocked did not seem useful. Many thanks

  • Upgrade of Ubuntu 8.10 distribution fails due to missing packages

    - by Tim
    I have a server that I've forgotten to upgrade for ages, which is still running Intrepid (8.10). I'd like to upgrade it to a newer version of the distribution, so that I can get security patches etc. I found some instructions that tell me to install the package update-manager-core. I tried the following: $ sudo apt-get install update-manager-core but this fails since some of the necessary packages can't be found: ... Err http://archive.ubuntu.com intrepid/main python-apt 0.7.7.1ubuntu4 404 Not Found [IP: 91.189.88.40 80] Err http://archive.ubuntu.com intrepid-updates/main update-manager-core 1:0.93.34 404 Not Found [IP: 91.189.88.40 80] Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/p/python-apt/python-apt_0.7.7.1ubuntu4_amd64.deb 404 Not Found [IP: 91.189.88.40 80] Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/u/update-manager/update-manager-core_0.93.34_amd64.deb 404 Not Found [IP: 91.189.88.40 80] ... I know that Intrepid is no longer supported, and so I guess some of the necessary files may no longer be maintained. But this seems rather unhelpful: I can't upgrade because it's too old, and the only way to fix this would be to upgrade it. Is there a way round this? Is something else wrong?

  • Router(s) Issue: DNS quries sporadically fail with multiple computers hooked in

    - by bob-the-destroyer
    Basically, after anywhere from 5-60 minutes, DNS queries fail for a few minutes, then slowly begin to resolve correctly. Then the cycle repeats. This occurs only when more than one computer is on the network. All computers on the network experiences the same sporadic DNS outage at the same time. Wireless or wired, Linux or Windows, fresh OS install or old, browser or ping, same symptoms. Duplicated on 3 routers (not chained together, mind you) and 3 ISP's and 3 separate locations over the past several months. The only common theme is a single 5-yo WIN XP laptop which has been in use on the network throughout all this. There also may be anywhere between 1 - 10 devices hooked up wired or wirelessly at a time. The only reprieve I have from this torture is by using any VPN to an outside source - always smooth sailing. I typically set up any router to a) use WPA2/etc security; b) MAC whitelist; c) UPNP OFF (if available); d) always update firmware when available; e) obtain DNS from ISP automatically; f) set the router to act as DHCP server for the internal network. Adjusting channels has no effect. Any ideas?

  • Single application through OpenVPN tunnel (Debian Lenny)

    - by user14124
    I'm using Debian Lenny and I want to tunnel rtorrent only through a OpenVPN tunnel. I have a tunnel running, the config file looks like this: client dev tun proto udp remote openvpn.xxx.com 1194 resolv-retry infinite nobind persist-key persist-tun ca /etc/openvpn/xxx/keys/ca.crt cert /etc/openvpn/xxx/keys/client.crt key /etc/openvpn/xxx/keys/client.key tls-auth /etc/openvpn/xxx/keys/tls.key 1 ns-cert-type server comp-lzo verb 3 auth-user-pass script-security 3 reneg-sec 0 My idea is that I could run a sockd proxy internally that redirects traffic to the openvpn tunnel. I could use the *nix "proxifier" application "tsocks" to make it possible for rtorrent to connect through that proxy (as rtorrent doesn't support proxies). I have trouble configuring sockd as my IP inside the VPN changes every time I connect. This is a config file someone said would help: http://ircpimps.org/sockd.conf As my IP changes at each connect I don't know what to put in that config file. I have no control over the host side config file. Any help wanted. Any other method is very welcome.

  • Copied a file with winscp; only winscp can see it

    - by nilbus
    I recently copied a 25.5GB file from another machine using WinSCP. I copied it to C:\beth.tar.gz, and WinSCP can still see the file. However no other app (including Explorer) can see the file. What might cause this, and how can I fix it? The details that might or might not matter WinSCP shows the size of the file (C:\beth.tar.gz) correctly as 27,460,124,080 bytes, which matches the filesize on the remote host Neither explorer, cmd (command line prompt w/ dir C:\), the 7Zip archive program, nor any other File Open dialog can see the beth.tar.gz file under C:\ I have configured Explorer to show hidden files I can move the file to other directories using WinSCP If I try to move the file to Users/, UAC prompts me for administrative rights, which I grant, and I get this error: Could not find this item The item is no longer located in C:\ When I try to transfer the file back to the remote host in a new directory, the transfer starts successfully and transfers data The transfer had about 30 minutes remaining when I left it for the night The morning after the file transfer, I was greeted with a message saying that the connection to the server had been lost. I don't think this is relevant, since I did not tell it to disconnect after the file was done transferring, and it likely disconnected after the file transfer finished. I'm using an old version of WinSCP - v4.1.8 from 2008 I can view the file properties in WinSCP: Type of file: 7zip (.gz) Location: C:\ Attributes: none (Ready-only, Hidden, Archive, or Ready for indexing) Security: SYSTEM, my user, and Administrators group have full permissions - everything other than "special permissions" is checked under Allow for all 3 users/groups (my user, Administrators, SYSTEM) What's going on?!

  • Samba access works with IP address only

    - by Sebastian Rittau
    I added a Debian etch host (hostname: webserver, IP address: 192.168.101.2) running Samba to a Windows network with a Windows 2003 PDC (IP address 192.168.101.3). The Samba server exports a public guest share, called "Intranet". The server shows up fine in the network, but trying to click on it produces an error dialog, stating I don't have the necessary permissions. So does entering \webserver manually and using \webserver\internet states that the path does not exist. Interestingly, accessing the share by IP address (\192.168.101.2 or \192.168.101.2\intranet) works fine. DNS is configured correctly, and "smbclient //webserver/intranet" on another Linux client works fine. One complicating issue is that the webserver is only a VMware virtual machine running on PDC server. Here is our smb.conf: [global] workgroup = Foobar server string = Webserver wins support = yes ; commenting out these wins server = 192.168.101.3 ; two lines has no effect dns proxy = no guest account = nobody [... snipped some unrelated bits, like logging ...] security = share [... snipped some password-related things ...] domain master = no [intranet] comment = Intranet path = /srv/webserver/contents browseable = yes guest ok = yes guest only = yes read only = yes create mask = 0775 directory mask = 0775

  • Can't access YouTube

    - by Agentleader1
    I can not seem to connect to YouTube at all. If I connect directly to YouTube (youtube.com) I get this: And if I try to connect via video directly (youtube.com/watch?v=), I get this: Here's how this isn't a web issue: I have malware on my computer I believe. And the question here is, how do I get rid of it, or what possible issue could this be? I can verify this is not a website issue or wifi issue, I've tried to connect on another computer in my wifi, and it worked. It is the local machine issue. I've tried to get rid of malware at my best and also have tried to disable possible virus extensions. All can out as the same result: no help. Also, I am unable to find these hiding viruses. I used malware-bytes and Microsoft Security Essentials. Edit: This is OBVIOUSLY Windows. I am currently running on a laptop Windows 7 Home Premium 4gb ram 64-bit os Lifebook series manufactured by Fujitsu America, Inc. Intel(R) Core(TM) i3-3110M CPU @ 2.40GHz nslookup youtube.com:

  • What is the correct approach i should use for an application that requires amazon S3 uploads and SimpleDB data management?

    - by Luis Oscar
    I am developing an application for iOS and that is going smoothly, the problem is that I am very new at server sided things. I am totally confused about how to correctly use Amazon Web Services for this purpose. What I want to do is very simple. I want my application to be able to query a servlet hosted in EC2 to be able to retrieve pictures and data based on some criteria from S3 and SImpleDB respectively. Also the application should be able to upload pictures into a S3 bucket and register the information in the SImpleDB. My main concerns are security and costs, So far i was using Amazon Token Vending Machine but I haven't been successful when trying to customize it, and while researching I discovered that on the long run it is very expensive. The ultimate goal is to handle a "social" picture service for my iOS application. Being able to register new users, authenticate these users. See what permissions they have to which pictures from the bucked. And all this without having to worry about Third party people from accessing the private pictures of my users. Sorry for this question but I am really clueless about how to handle this... I have tried reading many articles but all these server stuff looks very scary.

  • Svchost.exe connecting to different IPs with remote port 445

    - by Coll911
    Im using Windows XP Professional SP2. Whenever I start my Windows, svchost.exe starts connecting to all the possible IPs on LAN like from 192.168.1.2 to 192.168.1.200. The local port ranges from 1000-1099 and the remote port being 445. After it's done with the local IPs, it starts connecting to other random IPs. I tried blocking connections to the port 445 using the local security polices but it didn't work. Is there any possible way I could prevent svchost from connecting to these IPs without involving any firewall installed? My PC slows down due to the load. I scanned my PC with MalwareBytes and found out it was infected with a worm, it's deleted now but still svchost is connecting to the IPs. I also found out that in my Windows Firewall settings, under Internet Control Message Protocol (ICMP), there's a tick on "allow incoming echo request" (usually disabled) which is locked and I can't disable it. Its description is as follows Messages sent to this computer will be repeated back to the sender. This is used for trouble shooting for e.g to ping a machine. Requests of this type are automatically allowed if TCP port 445 is enabled. Any solutions? I can't bear going with the reinstalling Windows phase again.

  • Replicated filesystem and EC2 MySQL

    - by El Yobo
    I'm currently investigating migrating our infrastructure over to run on Amazon's EC2 and am trying to figure out the best way to set up a MySQL service. I'm leaning towards running our own MySQL instances, rather than going with Amazon's RDS, but am still considering the best approach for performance and cost on the instance itself. In order to have persistent data, the MySQL data needs to be on an EBS volume (with some form of striped RAID, e.g. RAID0 or RAID10) to improve persistence. However, EBS IO is limited by the network interface (gigabit, so a theoretical maximum of 128 MB/s), while the ephemeral volumes have no such problem. I did see a suggestion for running two MySQL servers on an instance, with a master running on the ephemeral disk (which we would also RAID) and a slave storing changes to an EBS volume, but this has some additional overhead and complexity (two servers). What I was imagining is using some form of replicated file system such that I could have a filesystem on top of a RAID0 of ephemeral volumes to maximise performance all changes from the above immediately replicated to another RAID1 volume backed by multiple EBS volumes to ensure no data loss The advantages of this would be best possible IO performance for the DB server; no network delay in IO decreased IO on EBS volumes (as all read IO will be done on the ephemeral volumes) so decreased cost good data security, as it's backed onto redundant EBS volumes However, I haven't seen an appropriate system to replicate all changes from one volume to the other; is there a filesystem, or any other approach, which will do this? The distributed file systems, e.g. GlusterFS, DRBD etc seem to focus on replicating disks between servers, can they be set up to do what I'm interested in here? I also haven't seen anything about other's taking this approach. Do I have a solution in need of a problem here (i.e. is performance good enough, so this whole idea is redundant)? Is there some flaw in the plan?
