• File transfer problems through VPN when Cisco IPS is enabled

  - by Richard West

  We have a Cisco ASA 5510 firewall with the IPS module installed. We have a customer that we must connect to via VPN to their network to exchange files via FTP. We use the Cisco VPN client (version 5.0.01.0600) on our local workstations, which are behind the firewall and subject to the IPS. The VPN client is successful in connecting to the remote site. However when we start the FTP file transfer we are able to upload only 150K to 200K of data, then everything stops. A minute later the VPN session is dropped. I think I have isolated this to an IPS issue by temporarily disabling the Service Policy on the ASA for the IPS with the following command: access-list IPS line 1 extended permit ip 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 inactive After this command was issued I then established the VPN to the remote site and was successful in transferring the entire file. While still connected to the VPN and FTP session I issued the command to enable the IPS: access-list IPS line 1 extended permit ip 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 The file transfer was tried again and was once again successful so I closed the FTP session and reopened it, while keeping the same VPN session open. This file transfer was also successful. This told me that nothing with the FTP programs was being filtered or causing the problem. Furthermore, we use FTP to exchange files with many sites everyday without issue. I then disconnected the original VPN session, which was established when the access-list was inactive, and reconnected the VPN session, now with the access-list active. After starting the FTP transfer the file stopped after 150K. To me this seems like the IPS is blocking, or somehow interfering with the initial VPN setup to the remote site. This only started happening last week after the latest IPS signature updates were applied (sig version 407.0). Our previous sig version was 95 days old becuase the system was not auto updating itself. Any ideas on what could be causing this problem?

• Cisco ASA Act as a Hardware Security Module?

  - by Derek

  Hello, We have a partner that is requiring us to get a HSM for a web application that we host for them. This is something new for us, we've always installed our SSL certificates on our web servers and never needed a hardware device. We currently have 2 Cisco ASA 5510 firewalls in an active/standby configuration. Both ASAs have a ASA-SSM-10 security module installed in them. The web application is a standard HTTPS webpage with no authentication required. I was wondering if we could use our Cisco ASAs to meet this requirement or if we'll have to buy another device. I was doing some searching and read about Cisco's clientless webvpn feature. It sounds like it might work, but I'm not sure. We basically want the ASA to handle the SSL and proxy the connection to our web servers. We do not want to prompt for a username or password to connect or show any portals, just display the web page. If the ASA cannot do this, does any one have any recommendations for network attached hardware security modules? We are using VMware vCenter, so we'd rather have an external device attached to the network, rather than buying HSM cards for every ESXi host. Thanks, Derek

• Wire VMWare Player NIC to a VLAN in Ubuntu 8.04.3

  - by Sophie Charlesworth

  Hi, I've got VMWare Player 2.5.x installed on a Ubuntu 8.04.3 host running CentOS 5.3 running Cobbler. VMWare Player has two NICs (I actually took this image from an ESXi image, converted it to Player 2.x image via VMWare Standalone Converter). I've also setup a vlan (vlan5) on the host with 10.0.0.x and I'd like Cobbler to use that VLAN to serve any incoming requests. How do I wire up my VMWare to use the VLAN I've setup? Just one of the NICs. What I'm trying to do is to offer a laptop with a VM that our sysadmins can go, plug it into a box (which does not connect to the interwebs) and install RHEL images via cobbler. So essentially, its a cross over cable from the network port on the lappy to the Dell server box. PXE boot in the dell box and install RHEL. I have the cobbler working fine under VMWare ESXi but not so on the VMWare Player because of the VLAN issue - I think. Any ideas?

• WordPress: can't access WordPress.com and other external sites?

  - by Rax Olgud

  Hello, I recently started a WordPress blog using hosting at MyDomain (they offer the application "natively"). The blog works fine, however I have two plugins I can't seem to install correctly. First, the WordPress.com Stats plugin requires the API Key. When I input it, I get the following message: Error from last API Key attempt: Your blog was unable to connect to WordPress.com. Please ask your host for help. (transport error - could not open socket: 110 Connection timed out) Second, the Akismet plugin is not configured. When I go to Akismet page to insert my API key, it has the following message: There was a problem connecting to the Akismet server. Please check your server configuration. I assume the two issues are related... I approached my hosting provider about the subject and all they said is that they don't support WordPress, only provide means to install it. To clarify, up to this point I have only been able to install plugins that don't require an API key. What can I do to diagnose the problem and fix it? As a work-around, are there comparable stats and anti-spam plugins that don't require an API key? Many thanks.

• Memcached session manager in Azure: Connection gets forcibly closed

  - by Edgar Pérez

  I am using Memcached Session Manager to handle Tomcat sessions in non-sticky mode. My deployment in Azure consists of a Worker Role with two instances which connect to an Azure VM running my Memcached server. Everything works pretty well, my session is persisted and retrieved by any of the two instances transparently. The problem arises when the session is idle for about 4 minutes; everything points out that the Azure Loadbalancer is closing the spymemcached connection to the VM after some period of inactivity. My MSM configuration is this: <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager" memcachedNodes="n1:my-azure-vm.cloudapp.net:11211" sticky="false" sessionBackupAsync="false" sessionBackupTimeout="10000" lockingMode="uriPattern:/path1|/path2" requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js|ttf|eot|svg|woff)$" transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory" customConverter="de.javakaffee.web.msm.serializer.kryo.HibernateCollectionsSerializerFactory"/> The stacktrace printed by the spymemcached client is this: INFO net.spy.memcached.MemcachedConnection: Reconnecting due to exception on {QA sa=/10.194.132.206:13000, #Rops=1, #Wops=0, #iq=0, topRop=net.spy.memcached.protocol.binary.StoreOperationImpl@1d95da8, topWop=null, toWrite=0, interested=1} java.io.IOException: An existing connection was forcibly closed by the remote host at sun.nio.ch.SocketDispatcher.read0(Native Method) at sun.nio.ch.SocketDispatcher.read(Unknown Source) at sun.nio.ch.IOUtil.readIntoNativeBuffer(Unknown Source) at sun.nio.ch.IOUtil.read(Unknown Source) at sun.nio.ch.SocketChannelImpl.read(Unknown Source) at net.spy.memcached.MemcachedConnection.handleReads (MemcachedConnection.java:303) at net.spy.memcached.MemcachedConnection.handleIO (MemcachedConnection.java:264) at net.spy.memcached.MemcachedConnection.handleIO (MemcachedConnection.java:184) at net.spy.memcached.MemcachedClient.run(MemcachedClient.java:1298) Given this idle time limitation in Azure, is there any other way to make MSM work in the azure cloud?

• No internet connection using Edimax routers

  - by idan315

  I have two computers connected to a router, connected to my ADSL modem by PPPoE. One of those computrs use Windows XP, the other uses Windows 7. The computer using Windows 7 keeps getting limited or no connectivity, and I can't use it to connect to the internet. Connecting the computer to the modem without the router 'in the way' worked, and I was able to use the internet - which led me to believe that the problem is with my router. However, I have changed my router, and the problem persists. I am really lost on how to approach this problem. Possible leads: when I view the network information, I see that my computer is connected to 'Multiple Networks'. One of those is "Network 4" (probably my router), and the other is Unidentified network. I don't know how to make the "Unidentified Network" disappear, or why is it even there in the first place. When I try using "ipconfig", I have two default gateway IPs. The first is 0.0.0.0, and the second is the IP of my router (192.168.2.1). The first router was Edimax BR-6204Wg. The second one I've tried connecting is BR-6424n. Any ideas?

• nginx subdomains improperly act like wildcard?

  - by binjured

  I have an odd problem with nginx subdomains. First, my configuration: server { listen 443 ssl; server_name secure.example.com; ssl_certificate example.crt; ssl_certificate_key example.key; keepalive_timeout 70; location / { fastcgi_pass 127.0.0.1:8000; ... } } server { listen 80; server_name example.com www.example.com; location / { fastcgi_pass 127.0.0.1:8000; ... } } The idea being that I have a secure domain, secure.example.com and a normal domain, example.com. In practice, I can go to https://example.com and http://secure.example.com. I worked around the second issue with an intermediary server: server { listen 80; server_name secure.example.com; rewrite ^(.*) https://secure.example.com$1 permanent; } But this is not an optimal solution and I'd have to create another one to redirect https on the tld to the subdomain. I feel like I must be doing something wrong if I need multiple servers like that. Why does https://example.com work when there is no server listening on 443 there? Shouldn't it just fail to connect? I'm rather confused.

• Reverse SSH Tunnel

  - by chris

  I am trying to forward web traffic from a remote server to my local machine in order to test out some API integration (tropo, paypal, etc). Basically, I'm trying to setup something similar to what tunnlr.com provides. I've initiated the ssh tunnel with the command $ssh –nNT –R :7777:localhost:5000 user@server Then I can see that server has is now listening on port 7777 with user@server:$netstat -ant | grep 7777 tcp 0 0 127.0.0.1:7777 0.0.0.0:* LISTEN tcp6 0 0 ::1:7777 :::* LISTEN $user@server:curl localhost:7777 Hello from local machine So that works fine. The curl request is actually served from the local machine. Now, how do I enable server.com:8888 to be routed through that tunnel? I've tried using nginx like so: upstream tunnel { server 0.0.0.0:7777; } server { listen 8888; server_name server.com; location / { access_log /var/log/nginx/tunnel-access.log; error_log /var/log/nginx/tunnel-error.log; proxy_pass http://tunnel; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_redirect off; } } From the nginx error log I see: [error] 11389#0: *1 connect() failed (111: Connection refused) I've been looking at trying to use iptables, but haven't made any progress. iptables seems like a more elegant solution than running nginx just for tunneling. Any help is greatly appreciated. Thanks!

• Wifi as LAN - Is it possible ? How ?

  - by sagar

  Hello ! Every one. I am having a query regarding WiFi network. I am having PC & LapTop. Now, Let me explain the situation. I requested My WiFi providers that I want connection in my PC. So that - WiFi provider set up an Antenna on my building Terrace - They joined a cable to pc & that Antenna. ( I think using RJ45 connector ) - The reason behind this - my pc is not having inbuilt wifi functionality. Now - almost laptops have inbuilt functionality. Now - On terrace there is wifi with superb speed. But on my flat - wifi comes with low speed. so, when ever I use internet on my pc - it has great speed - but my laptop works with low speed. The reason behind this - PC is catching wifi from terrace & laptop is catching the wifi from it's own place. Now, My question is something like this. Can we place an antenna or something like that & connect it to laptop for better wifi speed? ( I am not technical person - Please add comment for down vote - if any ) ( Please add comment for more explanation of my Problem ) Thanks in advance for sharing your knowledge. Sagar

• A network-related or instance-specific error occurred while establishing a connection to SQL Server

  - by sf

  Hi, I'm getting the following error when trying to load an Asp.NET MVC App on IIS 7 with Sql Server 2008 Express. The App uses Linq to SQL. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) I've done some searching and all answers point to enabling TCP connections in Sql Server Configuration which I have done to no avail. The connection string I am using is: Server=SERVERNAME\SQLEXPRESS;Database=DBName;Integrated Security=true The catch. I have another app that already could talk to the Sql Server just fine. Even before playing around with the Sql Server Configuration Settings. The other app uses the following connectionstring: Data Source=SERVERNAME\SQLEXPRESS;Initial Catalog=OtherDbName;Integrated Security=True;Persist Security Info=False;Connect Timeout=120 I've tried this connectionstring on the app that isn't working and it still doesn't work. Please help. I think i'm about to go crazy

• sftpd: No available certificate or key corresponds to the SSL cipher suites which are enabled?

  - by Arcturus

  Hello. I'm trying to setup vsftpd on Fedora 12. I need to require use of FTPS, and for now need to use a self-signed SSL certificate. I managed to get the vsftpd service running and to connect as my user. I can list the home directory, but as soon as I try to list another directory, download or upload a file, I get this error: No available certificate or key corresponds to the SSL cipher suites which are enabled. And the xfer log is empty. I've been Googling it for a while now, but still can't understand the problem. Here's how I installed vsftpd: su yum install vsftpd chkconfig vsftpd on service vsftpd start I tried to generate the certificate in two ways. Here's the first one: cd /etc/vsftpd openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout vsftpd.pem -out vsftpd.pem Here's the second way: cd /etc/pki/tls/certs make vsftpd.pem Here's my vsftpd configuration: anonymous_enable=NO local_enable=YES write_enable=YES local_umask=022 dirmessage_enable=YES xferlog_enable=YES connect_from_port_20=YES xferlog_file=/var/log/vsftpd.log xferlog_std_format=YES nopriv_user=ftpsecure chroot_local_user=YES chroot_list_enable=YES chroot_list_file=/etc/vsftpd/chroot_list listen=YES pam_service_name=vsftpd userlist_enable=YES tcp_wrappers=YES # SSL settings ssl_enable=YES force_local_data_ssl=YES force_local_logins_ssl=YES rsa_cert_file=/etc/pki/tls/certs/vsftpd.pem allow_anon_ssl=NO ssl_tlsv1=YES ssl_sslv2=NO ssl_sslv3=NO Does anyone know what the problem is and how to solve it?

• ip-up does not trigger when using built-in cisco vpn on mac osx lion

  - by Yasser Sobhdel

  I am using Cisco VPN client over lion and I want to make the ip-up and ip-down work. There is no sign of any action taken when I connect or disconnect this VPN connection. I really doubt whether the syntax has been changed or even this kind if connection is triggering the ip-up. Logically, it must be set over ppp but when using the following codes and instructions on them, there is no sign of any output in the log file: http://www.macfreek.nl/mindmaster/Modify_PPTP_Routing_Table http://www.aidanfindlater.com/use-vpn-for-specific-sites-on-mac-os-x Going for error, which there is no sign of it, using the following page: http://hints.macworld.com/article.php?story=20060616150640529 I couldn't find the /var/log/ppp/vpnd.log log file. Also the files are given full permission 0755 or a+x or even 777 using the following command: sudo chmod a+x /etc/ppp/ip-up Any clue on how to debug this would be appreciated. I am totally confused, netstat -rn -f inet doesn't show the routes. Even when the routes are added manually, closing the VPN connection does not run the ip-down and the routes must be deleted manually.

• Configuration management in support of scientific computing

  - by Sharpie

  For the past few years I have been involved with developing and maintaining a system for forecasting near-shore waves. Our team has just received a significant grant for further development and as a result we are taking the opportunity to refactor many components of the old system. We will also be receiving a new server to run the model and so I am taking this opportunity to consider how we set up the system. Basically, the steps that need to happen are: Some standard packages and libraries such as compilers and databases need to be downloaded and installed. Some custom scientific models need to be downloaded and compiled from source as they are not commonly provided as packages. New users need to be created to manage the databases and run the models. A suite of scripts that manage model-database interaction needs to be checked out from source code control and installed. Crontabs need to be set up to run the scripts at regular intervals in order to generate forecasts. I have been pondering applying tools such as Puppet, Capistrano or Fabric to automate the above steps. It seems perfectly possible to implement most of the above functionality except there are a couple usage cases that I am wondering about: During my preliminary research, I have found few examples and little discussion on how to use these systems to abstract and automate the process of building custom components from source. We may have to deploy on machines that are isolated from the Internet- i.e. all configuration and set up files will have to come in on a USB key that can be inserted into a terminal that can connect to the server that will run the models. I see this as an opportunity to learn a new tool that will help me automate my workflow, but I am unsure which tool I should start with. If any member of the community could suggest a tool that would support the above workflow and the issues specific to scientific computing, I would be very grateful. Our production server will be running Linux, but support for OS X would be a bonus as it would allow the development team to setup test installations outside of VirtualBox.

• Sonicwall routing between multiple subnets on multiple interfaces

  - by Rain

  As shown by the network diagram below, I have two completely separate networks. One is being managed by a Sonicwall NSA 220, the other by some other router (the brand is not important). My goal is to allow devices within the 192.168.2.0/24 network to access devices in the 192.168.3.0/24 network. Allowing the reverse (192.168.3.0/24 - 192.168.2.0/24) is not required. So far, I have done the following: I connected the X3 Interface on the Sonicwall to the 192.168.3.0/24 network switch (shown as the dashed red line in the diagram). Next, I gave it a static ip address of 192.168.3.254 and set the Zone to LAN (the same Zone for the X0 interface). Judging by various articles and KBs I've read, this is all that should be necessary, although it does not work. I can ping 192.168.3.254 from any device in the 192.168.2.0/24 network although I cannot ping/connect to any device within the 192.168.3.0/24 network. Any help would be greatly appreciated! Network Diagram: (I asked a similar, yet more complicated, question earlier; although, I realized that I cannot solve that without first solving this (which may actually solve my original question))

• iPod touch has extremely slow wifi, drops packets - only on my router

  - by mskfisher

  I just purchased an iPod Touch. I am having a lot of trouble with its speeds on my Tenda W311R, but it has no speed problems on my neighbor's Netgear router. It will connect and authenticate to my network, but the Speed Test app from speedtest.net shows rates near 20-50 kbps. If I run the speed test immediately after powering the iPod on, it will get speeds of 10-20 Mbps, like it should - but the speeds slow down to the kbps range abut 10-15 seconds afterward. I get the same behavior with encryption and without encryption, and regardless of N, G, or B compatibility settings in the router. I've tried rebooting the iPod and resetting the network settings, but it's still slow. I've tried pinging the iPod from another computer, and it shows about 40% packet loss: $ ping 192.168.0.111 PING 192.168.0.111 (192.168.0.111): 56 data bytes 64 bytes from 192.168.0.111: icmp_seq=0 ttl=64 time=14.188 ms 64 bytes from 192.168.0.111: icmp_seq=1 ttl=64 time=11.556 ms 64 bytes from 192.168.0.111: icmp_seq=2 ttl=64 time=5.675 ms 64 bytes from 192.168.0.111: icmp_seq=3 ttl=64 time=5.721 ms Request timeout for icmp_seq 4 64 bytes from 192.168.0.111: icmp_seq=5 ttl=64 time=6.491 ms Request timeout for icmp_seq 6 64 bytes from 192.168.0.111: icmp_seq=7 ttl=64 time=8.065 ms Request timeout for icmp_seq 8 Request timeout for icmp_seq 9 Request timeout for icmp_seq 10 64 bytes from 192.168.0.111: icmp_seq=11 ttl=64 time=9.605 ms Signal strength is good - I'm never more than 20 feet from my access point, and it exhibits the same behavior if I'm standing next to the router. It works just well enough to receive text, but videos don't work at all. App downloads are hit and miss. I've tweaked just about all of the settings I can see to tweak, and I'm at a loss. I have also been searching Google for the past three days, all to no avail. Any suggestions?

• Is there a way to tell what the download speed is from a site/server

  i'm looking into which ISP i should go with at the place i'm moving into, one ISP which i have been told good things about has data limits (which when breached will drop your speed to dial-up speed) but multiple memberships which, apart from the cheapest membership, have the same data limits (the cheapest has a 10GB data limit) in their fine print, they say that each different membership has different port speeds, one particular part jumps out at me These speeds are the NBN (National Broadband Network) port speed and not the actual Internet data speed which will vary based on numerous factors including destination you are reaching, your network equipment, network congestion etc. i plan to use the net to download DLC and patch updates for games (particular the insanely large update for the Wii U) and games from Steam (if i find any good one other than this one JRPG) and downloading development resources from free sites like Deposit Files and Mediafire since one membership with a 1000GB data limit is $145 with the port speed being 12Mbps/1Mbps (cheapest) while another with the same limit is $190 with the port speed of 100Mbps/40Mbps (expensive) i am wondering how i can tell what the speed coming from site is since i don't want to be wasting money on speed that makes no difference (unlike memory which i rather have to spare) NOTE: the speeds are for a fiber optic network which where my new place is can only connect via fixed wireless which i may not be able to get with this ISP but if i can get this network then good NOTE 2: most of the resources i get from Deposit Files are always about 200 MB or less, if a resource pack is greater then it's split into multiple archives (like .7z.part) while Mediafire i have to see one bigger than 150MB NOTE 3: one update patch for a PS3 game is close to 4 GB (Disgaea 4) which i need to get access to the DLC and on the weekend i downloaded 5 GB for the Final Fantasy XIV Open Beta for the PS3 which took almost 5 hours

• SSH Tunnel for Remote Desktop via Intermediary Server Part II

  - by Mihai Todor

  I asked previously how to configure 2 SSH tunnels using an intermediary server in order to run Remote Desktop through them and I managed to make it work. Now, I'm trying to do the same, using the same machines, but in reverse order. Here's the setup: Windows 7 PC in a private network, sitting behind a firewall. Public access Linux server, which has access to the PC. Windows 7 laptop, at home, on which I wish to do Remote Desktop from the PC. I use Putty on the laptop to create a reverse tunnel from it to the Linux server: R60666 localhost:3389. I use Putty on the PC to create a regular tunnel from it to the Linux server: L60666 localhost:60666. I SSH to the Linux sever and I run telnet localhost 60666 and it seems to produce the expected output, as described in the debugging tips that I received here. I try to connect Remote Desktop from the PC to the laptop: localhost:60666. It asks for my username and password, I click OK and it locks my current session on the laptop (so I see the welcome screen on the laptop instead of my desktop), it shows the "Welcome" message in the Remote Desktop screen and then it just goes black. It doesn't disconnect, it doesn't provide any error and I'm not able to perform any actions in the Remote Desktop screen. I tried the same setup with a Windows XP laptop and I'm experiencing the same symptoms. I also tried to use different ports than 60666, but nothing changed. Does anybody have any idea what I'm doing wrong? Update: As pointed out by @jwinders, I'm not able to run telnet PC 3389 from the Linux server directly. Since Windows Firewall has a rule to allow all connections on port 3389, I have no idea what is blocking it. Fortunately, I'm able to create a SSH tunnel from the Linux machine to the PC ssh 3389:localhost:3389 'domain\user'@PC.

• postfix Mail filters not running behind a controlled enviornment

  - by Ashish

  Hi, I have deployed a postfix server for email receiving. On this I have configured SenderID + SPF milter, by referring to http://www.postfix.org/MILTER_README.html The command that I used is as follows: ./sid-filter -u postfix -p inet:10027@localhost -l Following are my settings in main.cf file: #Milter support for smtpd mail smtpd_milters = inet:localhost:10027, inet:localhost:10028 # Milters for non-SMTP mail. non_smtpd_milters = inet:localhost:10027, inet:localhost:10028 milter_default_action = reject # Postfix . 2.6 #milter_protocol = 6 # 2.3 . Postfix . 2.5 milter_protocol = 2 Now I have this observation: One of the postfix that is setup on AWS CentOS 5.5 is working fine and is able to receive mails on defined mx record. One of the similar postfix(as in step 1) that is setup behind one of the corporate firewalls is not able to receive any mails and is giving following type of error logs: connect from xxxxxx.austin.hp.com[xx.xxx.96.198] May 25 13:20:02 g2t0385g postfix/smtpd[11733]: C11F9B0194: client=xxxxxxx.austin.hp.com[15.217.96.198] May 25 13:20:03 g2t0385g postfix/cleanup[11814]: C11F9B0194: message-id= May 25 13:20:03 g2t0385g postfix/cleanup[11814]: C11F9B0194: milter-reject: END-OF-MESSAGE from xxxxxx.austin.hp.com[xx.xxx.96.198]: 5.7.1 Command rejected; from= to= proto=ESMTP helo= Here the 'sid-filter' is giving problems. Any idea, what I am doing wrong? Please help. Thanks in advance Ashish Sharma

• rr.com appended to URL and I don't know why

  - by Steph

  I've been having some pretty bad and intermittent internet connectivity issues. I keep getting timeouts on my browsers, or what appears to be timeouts on my browsers. In Chrome it's generally error 21. FF it times out. And so on. While this is happening, I can go into the command line and ping or traceroute the same domain and it works fine. I use my cellphone on the same network and it's fine connecting to the same domain. And when it fails, it's all domains that are down in all browsers, chrome, FF, etc. I also noticed that when I try to connect to 192.168.1.1 it says in chrome did you mean www.192.168.1.1rr.com but when I enter https://192.168.1.1 it's fine. It only seems to do this in Chrome. This is making me think I have a virus. I did some researching about something called road runner, but I can't find any related traces. I also ran a full virus scan using nod32 (eset) and nothing. Any suggestion or help would be greatly appreciated. The intermittent loss of total internet access is really annoying and I'm worried about why it's trying to append the rr.com domain in Chrome. I suspect I'm dealing with two different issues, but you never know. Also for the DNS I'm using Google's DNS servers, the famous 8.8.8.8 and 8.8.8.4

• PXE bootable image for terminal server?

  - by HeavenCore

  We have 300 windows xp machines on cruddy old hardware across the company. With extended support for XP ending April next year we're looking into our options. Couple of options: Replace the 300 PC's with full windows 7 PC's (£100k +?) - no use of terminal server (our current model) Replace the 300 PC's with off the shelf thin clients & make use of our terminal server - Cheaper clients but Terminal Server CALS required? Keep the 300 PC's, replace windows XP with linux thin client capable of connecting to our terminal server - no hardware costs, just Terminal Server CALS required? Keep the 300 PC's - remove hard drives and make use of a PXE bootable "thin client" to connect to our terminal server If we were to choose option 4, what our the options out there? Is there any official PXE bootable thin clients for terminal server out there? If so, what are the licence requirements? Is there options we haven’t considered? There must be lots of companies out there in this situation - curious what the current trend is for this problem? Edit: Option 5 - Create a bootable Windows PE image with RDP auto start and use that as a "thin client" for our terminal server - is Windows PE licence free in such a model?

• MySQL remote access not working - Port Close?

  - by dave.zap

  I am not able to get a remote connection established to MySQL. From my pc I am able to telnet to 3306 on the existing server, but when I try the same with the new server it hangs for few minutes then returns # mysql -utest3 -h [server ip] -p Enter password: ERROR 2003 (HY000): Can't connect to MySQL server on '[server ip]' (110) Here is some output from the server. # nmap -sT -O localhost -p 3306 ... PORT STATE SERVICE 3306/tcp closed mysql ... # netstat -anp | grep mysql tcp 0 0 [server ip]:3306 0.0.0.0:* LISTEN 6349/mysqld unix 2 [ ACC ] STREAM LISTENING 12286 6349/mysqld /DATA/mysql/mysql.sock # netstat -anp | grep 3306 tcp 0 0 [server ip]:3306 0.0.0.0:* LISTEN 6349/mysqld unix 3 [ ] STREAM CONNECTED 3306 1411/audispd # lsof -i TCP:3306 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME mysqld 6349 mysql 10u IPv4 12285 0t0 TCP [domain]:mysql (LISTEN) I am running... OS CentOS release 5.8 (Final) mysql 5.5.28 (Remi) Note: Internal connections to mysql work fine. I have disabled IPtables, the box has no other firewall, it runs Apache on port 80 and ssh no problem. Had followed this tutorial - http://www.cyberciti.biz/tips/how-do-i-enable-remote-access-to-mysql-database-server.html I have bound the IP address in my.cnf user=mysql bind-address = [sever ip] port=3306 I even started over by deleting the mysql folder in my datastore and running mysql_install_db --datadir=/DATA/mysql --force Then recreated all the users as per the manual... http://dev.mysql.com/doc/refman/5.5/en/adding-users.html I have created one test user CREATE USER 'test'@'%' IDENTIFIED BY '[password]'; GRANT ALL PRIVILEGES ON *.* TO 'test'@'%' WITH GRANT OPTION; FLUSH PRIVILEGES; So all I can see is that the port is not really open. Where else might I look? thanks
