  • Unable to connect to Postgres on Vagrant Box - Connection refused

    - by Ben Miller
    First off, I'm new to Vagrant and Postgres. I created my Vagrant instance using http://files.vagrantup.com/lucid32.box with out any trouble. I am able to run vagrant up and vagrant ssh with out issue. I followed the instructions http://blog.crowdint.com/2011/08/11/postgresql-in-vagrant.html with one minor alteration. I installed "postgresql-8.4-postgis" package instead of "postgresql postgresql-contrib" I started the server using: postgres@lucid32:/home/vagrant$ /etc/init.d/postgresql-8.4 start While connected to the vagrant instance I can use psql to connect to the instance with out issue. In my Vagrantfile I had already added: config.vm.forward_port 5432, 5432 but when I try to run psql from localhost I get: psql: could not connect to server: Connection refused Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432"? I'm sure I am missing something simple. Any ideas? Update: I found a reference to an issue like this and the article suggested using: psql -U postgres -h localhost with that I get: psql: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.

  • How to know about MySQL 'refused connections'

    - by celalo
    Hello, I am using MONyog to montitor my two mysql servers. I get alert emails from MONyog when something goes wrong. There is an error I could not find out why. It says: Connection History: Percentage of refused connections) - 66.67% the percentage is not important, this is just about having refused connections. I get this email every half an hour. So this is like a constant situation. This must be my mistake, because I just set up those servers and there is no chance somebody else could be interfering the servers. MONyog advices me: Try to isolate users/applications that are using an incorrect password or trying to connect from unauthorized hosts. A client will be disallowed to connect if it takes more than connect_timeout seconds to connect. Set the value of log_warnings system variable to 2. This will force the MySQL server to log further information about the error. I added log_warnings=2 to my.cnf and I enabled logging like this: [mysqld_safe] . . log_warnings=2 log-error = /var/log/mysql/error.log . . . . [mysqld_safe] . log-error=/var/log/mysqld.log . . I cannot see any warnings at /var/log/mysql/error.log I can see some warnings at /var/log/mysqld.log but they are about something else. In sum, my question is how can I detect refused connections? Please let me know if any more info is required. Thanks in advance.

  • WCF- "The underlying connection was closed: The connection was closed unexpectedly"

    - by SumGuy
    Hi there. I'm recieving that wonderfuly ambiguous error message when using one of my webmethods on my WCF webservice. As that error message doesn't provide any explanation whatsoever allow me to post my theory. I believe it may have something to do with the return type I'm using I have a Types DLL which is refrenced in both the webservice and the client. In this DLL is the base class ExceptionMessages. There is a child of this class called DrawingExcepions. Here is some code: public class ExceptionMessages { public object[] ReturnValue { get; set; } } public class DrawingExceptions : ExceptionMessages { private List<DrawingException> des = new List<DrawingException>(); } public class DrawingException { public Exception ExceptionMsg { get; set; } public List<object> Errors { get; set; } } The using code: [OperationContract] ExceptionMessages createNewBom(Bom bom, DrawingFiles dfs); public ExceptionMessages createNewBOM(Bom bom, DrawingFiles dfs) { return insertAssembly(bom, dfs); } public DrawingExceptions insertAssembly(Bom bom, DrawingFiles dfs) { DrawingExceptions des = new DrawingExceptions(); foreach (DrawingFile d in dfs.drawingFiles) { DrawingException temp = insertNewDrawing(bom, d); if (temp != null) des.addDrawingException(temp); if (d.Child != null) des.addDrawingException(insertAssembly(bom, d.Child)); } return des; } Returns to: ExceptionMessages ems = client.createNewBom(bom, currentDFS); if (ems is DrawingExceptions) { } Basically the return type from the webmethod is ExceptionMessages however I would usually be sending the child class back instead. My only idea is that it's the child that's causing the error but as far as I've read, this should have no effect. Has anyone got any ideas what could be going wrong here? If any more info is required, just ask :) Thanks.

  • Connection refused after installing vsftp on Ubuntu 8.04 with fail2ban

    - by Patrick
    I have been using an Ubuntu 8.04 server with fail2ban for a while now (12+ months) and using ftp over SSH without any problems. I have a new user that needs to put files onto the server from an IP modem. I have installed vsftp (sudo apt-get install vsftp) and everything installed correctly. I have created an ftp user on the server following this guide. Whenever I try to connect to the server with my ftp program (filezilla) I get an immediate response of: Connection attempt failed with "ECONNREFUSED - Connection refused by server". I have looked into fail2ban and cannot find any problems. The iptables setup is: Chain INPUT (policy ACCEPT) target prot opt source destination fail2ban-ssh tcp -- anywhere anywhere multiport dports ssh Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination Chain fail2ban-ssh (1 references) target prot opt source destination RETURN all -- anywhere anywhere VSFTP config file (commented lines removed) listen=YES anonymous_enable=NO local_enable=YES write_enable=YES dirmessage_enable=YES xferlog_enable=YES connect_from_port_20=YES chown_uploads=YES chown_username=[username] secure_chroot_dir=/var/run/vsftpd pam_service_name=vsftpd rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key Any ideas on what is preventing access to the server?

  • postfix - connection refused from behind NAT

    - by manchine
    When attempting to telnet postfix from a different host in the same LAN through the FQDN (and thus the LAN's public IP), the following error occurs: root@mailer:/var/log# telnet mail.domain.com 25 Trying 1.2.3.4... telnet: Unable to connect to remote host: Connection refused Other services can be reached from the exact same host, however: root@mailer:/var/log# telnet mail.domain.com 22 Trying 1.2.3.4... Connected to mail.domain.com. Escape character is '^]'. SSH-2.0-OpenSSH_6.0p1 Debian-4+deb7u1 To make matters more intriguing, Postfix can be accessed from outside the LAN: nunos-mbp:mailog nzimas$ telnet mail.domain.com 25 Trying 1.2.3.4... Connected to mail.domain.com. Escape character is '^]'. 220 mail.domain.com ESMTP Postfix (Ubuntu) To sum thing up: a) Postfix (running on 10.10.10.4 / mail.domiain.com) refuses connection from a host in the same LAN (10.10.10.2), but only when queried through the FQDN (mail.domain.com) b) mail.domain.com accepts connections to other services (but Postfix) from 10.10.10.2 c) mail.domain.com accepts connections to all services, including Postfix, from the outside world If it were a firewall issue, then I believe it would not be possible to connect to any service from 10.10.10.2 through the FQSN / public IP. It ought to be some missing parameter in Postfix, although I haven't found any clear pointers so far.

  • Postgresql connection refused

    I'm trying to remotely connect to my postgresql database. I have two virtual machines set up both running ubuntu 14.04. I am trying to connect to the second vm using the first vm using psql -h 10.0.1.23 -U postgres -d postgres But I receive the error: Could not connect to server: Connection refused Is the server running on host "10.0.1.23" and accepting TCP/IP connections on port 5432?

  • Connection Pooling is Busted

    - by MightyZot
    A few weeks ago we started getting complaints about performance in an application that has performed very well for many years.  The application is a n-tier application that uses ADODB with the SQLOLEDB provider to talk to a SQL Server database.  Our object model is written in such a way that each public method validates security before performing requested actions, so there is a significant number of queries executed to get information about file cabinets, retrieve images, create workflows, etc.  (PaperWise is a document management and workflow system.)  A common factor for these customers is that they have remote offices connected via MPLS networks. Naturally, the first thing we looked at was the query performance in SQL Profiler.  All of the queries were executing within expected timeframes, most of them were so fast that the duration in SQL Profiler was zero.  After getting nowhere with SQL Profiler, the situation was escalated to me.  I decided to take a peek with Process Monitor.  Procmon revealed some “gaps” in the TCP/IP traffic.  There were notable delays between send and receive pairs.  The send and receive pairs themselves were quite snappy, but quite often there was a notable delay between a receive and the next send.  You might expect some delay because, presumably, the application is doing some thinking in-between the pairs.  But, comparing the procmon data at the remote locations with the procmon data for workstations on the local network showed that the remote workstations were significantly delayed.  Procmon also showed a high number of disconnects. Wireshark traces showed that connections to the database were taking between 75ms and 150ms.  Not only that, but connections to a file share containing images were taking 2 seconds!  So, I asked about a trust.  Sure enough there was a trust between two domains and the file share was on the second domain.  Joining a remote workstation to the domain hosting the share containing images alleviated the time delay in accessing the file share.  Removing the trust had no affect on the connections to the database. Microsoft Network Monitor includes filters that parse TDS packets.  TDS is the protocol that SQL Server uses to communicate.  There is a certificate exchange and some SSL that occurs during authentication.  All of this was evident in the network traffic.  After staring at the network traffic for a while, and examining packets, I decided to call it a night.  On the way home that night, something about the traffic kept nagging at me.  Then it dawned on me…at the beginning of the dance of packets between the client and the server all was well.  Connection pooling was working and I could see multiple queries getting executed on the same connection and ethereal port.  After a particular query, connecting to two different servers, I noticed that ADODB and SQLOLEDB started making repeated connections to the database on different ethereal ports.  SQL Server would execute a single query and respond on a port, then open a new port and execute the next query.  Connection pooling appeared to be broken. The next morning I wrote a test to confirm my hypothesis.  Turns out that the sequence causing the connection nastiness goes something like this: Make a connection to the database. Open a result set that returns enough records to require multiple roundtrips to the server. For each result, query for some other data in the database (this will open a new implicit connection.) Close the inner result set and repeat for every item in the original result set. Close the original connection. Provided that the first result set returns enough data to require multiple roundtrips to the server, ADODB and SQLOLEDB will start making new connections to the database for each query executed in the loop.  Originally, I thought this might be due to Microsoft’s denial of service (ddos) attack protection.  After turning those features off to no avail, I eventually thought to switch my queries to client-side cursors instead of server-side cursors.  Server-side cursors are the default, by the way.  Voila!  After switching to client-side cursors, the disconnects were gone and the above sequence yielded two connections as expected. While the real problem is the amount of time it takes to make connections over these MPLS networks (100ms on average), switching to client-side cursors made the problem go away.  Believe it or not, this is actually documented by Microsoft, and rather difficult to find.  (At least it was while we were trying to troubleshoot the problem!)  So, if you’re noticing performance issues on slower networks, or networks with slower switching, take a look at the traffic in a tool like Microsoft Network Monitor.  If you notice a high number of disconnects, and you’re using fire-hose or server-side cursors, then try switching to client-side cursors and you may see the problem go away. Most likely, Microsoft believes this to be appropriate behavior, because ADODB can’t guarantee that all of the data has been retrieved when you execute the inner queries.  I’m not convinced, though, because the problem remains even after replacing all of the implicit connections with explicit connections and closing those connections in-between each of the inner queries.  In that case, there doesn’t seem to be a reason why ADODB can’t use a single connection from the connection pool to make the additional queries, bringing the total number of connections to two.  Instead ADO appears to make an assumption about the state of the connection. I’ve reported the behavior to Microsoft and am awaiting to hear from the appropriate team, so that I can demonstrate the problem.  Maybe they can explain to us why this is appropriate behavior.  :)

  • Check connection and reconnect wifi

    - by Ruud
    I'm building a wireless photoframe. The one thing I haven't been able to figure out is how to get my wifi connection back up using a recommended method. Right now I edited /etc/network/interfaces so wlan0 is started at boot: auto wlan0 iface wlan0 inet dhcp wireless-essid ourssid This method works fine for booting. But I found that if I do not check the connection for a long time (could be a week) it might be down. So I should reconnect. What I do now to verify the connection is working is downloading a file from the server that can't be cached (http://server.ext/ping.php?randomize=123456) If I fail to retrieve the file I assume that the connection is no longer working and I run a shell script like #!/bin/bash ifconfig wlan0 up iwconfig wlan0 essid "ourssid" dhclient wlan0 And the connection comes back. But I can't find anything if this is in any way a good method. Can this be improved upon, or is this already right?

  • Software centre and Evolution think I am offline using WICD to make wireless connection

    - by Alex
    I upgraded to 11.10 yesterday. I use WICD to make the wireless connection because I have never managed to get network manager to make a wireless connection on any computer I have installed it on. But since 11.10 both Evolution and software centre are convinced I am offline even though I have a functional connection (I am using wifi now and both are reporting me offline, which I clearly am not). I am using an MSI WIND clone Advent 4211 B netbook. Network manager has never worked on this computer for wifi. WICD can make connection about 30% time (often returns BAD PASSWORD, first few attempts). XP of course works fine to make wifi connection. I have a I am happy to supply more information I just do not know what information might help. I have reported a bug against evolution

  • Can't connect to svnserve on localhost - connection actively refused

    - by RMorrisey
    When I try to connect using Tortoise to my SVN server using: svn://localhost/ Tortoise tells me: "Can't connect to host 'localhost'. No connection could be made because the target machine actively refused it." How can I fix this? I am trying to set up a subversion server on my local PC for personal use. I am running Windows Vista, with SlikSVN and TortoiseSVN installed. I previously had everything working correctly, but I found that I couldn't merge(!), apparently due to a version mismatch between the SVN client and server. Anyway... I now have the following setup: I created a repository using svnadmin create; it resides at C:\svnGrove C:\svnGrove\conf\svnserve.conf (# comments omitted): [general] anon-access=read auth-access=write password-db=passwd #authz-db=authz realm=svnGrove C:\svnGrove\conf\passwd: [users] myname=mypass My Subversion Server service is pointed to: C:\Program Files\SlikSvn\bin\svnserve.exe --service -r C:\svnGrove It shows the TCP/IP service as a dependency. I have also tried running svnserve from the command line, with similar results. The below is provided by the 'about' option in TortoiseSVN: TortoiseSVN 1.6.10, Build 19898 - 32 Bit , 2010/07/16 15:46:08 Subversion 1.6.12, apr 1.3.8 apr-utils 1.3.9 neon 0.29.3 OpenSSL 0.9.8o 01 Jun 2010 zlib 1.2.3 The following is from svn --version on the command line (not sure why it says CollabNet, CollabNet was the previous SVN binary that I had set up. The uninstaller failed to remove everything gracefully): svn, version 1.6.12 (SlikSvn/1.6.12) WIN32 compiled Jun 22 2010, 20:45:29 Copyright (C) 2000-2009 CollabNet.

Edit The old version of svnserve was still set up as a service after the uninstall, pointed to this path: C:\Program Files\Subversion\svn-win32-1.4.6\bin I edited the registry key for the service to point to the new path (shown above).

  • SSH Connection Refused - Debug using Recovery Console

    - by olrehm
    Hey everyone, I have found a ton of questions answered about debugging why one cannot connect via SSH, but they all seem to require that you can still access the system - or say that without that nothing can be done. In my case, I cannot access the system directly, but I do have access to the filesystem using a recovery console. So this is the situation: My provider made some kernel update today and in the process also rebooted my server. For some reason, I cannot connect via SSH anymore, but instead get a ssh: connect to host mydomain.de port 22: Connection refused I do not know whether sshd is just not running, or whether something (e.g. iptables) blocks my ssh connection attempts. I looked at the logfiles, none of the files in /var/log contain any mentioning on ssh, and /var/log/auth.log is empty. Before the kernel update, I could log in just fine and used certificates so that I would not need a password everytime I connect from my local machine. What I tried so far: I looked in /etc/rc*.d/ for a link to the /etc/init.d/ssh script and found none. So I am expecting that sshd is not started properly on boot. Since I cannot run any programs in my system, I cannot use update-rc to change this. I tried to make a link manually using ln -s /etc/init.d/ssh /etc/rc6.d/K09sshd and restarted the server - this did not fix the problem. I do not know wether it is at all possible to do it like this and whether it is correct to create it in rc6.d and whether the K09 is correct. I just copied that from apache. I also tried to change my /etc/iptables.rules file to allow everything: # Generated by iptables-save v1.4.0 on Thu Dec 10 18:05:32 2009 *mangle :PREROUTING ACCEPT [7468813:1758703692] :INPUT ACCEPT [7468810:1758703548] :FORWARD ACCEPT [3:144] :OUTPUT ACCEPT [7935930:3682829426] :POSTROUTING ACCEPT [7935933:3682829570] COMMIT # Completed on Thu Dec 10 18:05:32 2009 # Generated by iptables-save v1.4.0 on Thu Dec 10 18:05:32 2009 *filter :INPUT ACCEPT [7339662:1665166559] :FORWARD ACCEPT [3:144] :OUTPUT ACCEPT [7935930:3682829426] -A INPUT -i lo -j ACCEPT -A INPUT -p tcp -m tcp --dport 25 -j ACCEPT -A INPUT -p tcp -m tcp --dport 993 -j ACCEPT -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT -p tcp -m tcp --dport 143 -j ACCEPT -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT -A INPUT -p tcp --dport 8080 -s localhost -j ACCEPT -A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: " --log-level 7 -A INPUT -j ACCEPT -A FORWARD -j ACCEPT -A OUTPUT -j ACCEPT COMMIT # Completed on Thu Dec 10 18:05:32 2009 # Generated by iptables-save v1.4.0 on Thu Dec 10 18:05:32 2009 *nat :PREROUTING ACCEPT [101662:5379853] :POSTROUTING ACCEPT [393275:25394346] :OUTPUT ACCEPT [393273:25394250] COMMIT # Completed on Thu Dec 10 18:05:32 2009 I am not sure this is done correctly or has any effect at all. I also did not find any mentioning of iptables in any file in /var/log. So what else can I do? Thank you for your help.

    We have a custom function AppSettings.GetConnectionString() which is always called to determine the connection string that should be used. How this function works is unimportant to the discussion. It suffices to say that it returns a connection string and I have to use it. I want my LINQ to SQL DataContext to use this so I removed all connection string informatin from the dbml file and created a partial class with a default constructor like this: public partial class SampleDataContext { public SampleDataContext() : base(AppSettings.GetConnectionString()) { } } This works fine until I use the designer to drag and drop a table into the diagram. The act of dragging a table into the diagram will do several unwanted things: A settings file will be created A app.config file will be created My dbml file will have the connection string embedded in it All of this is done before I even save the file! When I save the diagram the designer file is recreated and it will contain its own default constructor which uses the wrong connection string. Of course this means my DataContext now has two default constructors and I can't build anymore! I can undo all of these bad things but it is annoying. I have to manually remove the connection string and the new files after each change! Is there anyway I can stop the designer from making these changes without asking? EDIT The requirement to use the AppSettings.GetConnectionString() method was imposed on me rather late in the game. I used to use something very similar to what it generates for me. There are quite a few places that call the default constructor. I am aware that change them all to create the data context in another way (using a different constructor, static method, factory, ect..). That kind of change would only be slightly annoying since it would only have to be done once. However, I feel, that it is sidestepping the real issue. The dbml file and configuration files would still contain an incorrect, if unused, connection string which at best could confuse other developers.

  • MacBook Pro 10.6 losing dns service, network connection still functional if you know the ip address.

    - by Vincent
    MacBook pro connected to a wireless network (not sure about wired) I lose DNS. I still have a functioning connection and as long as I know the ip address of the website, server... for example skype works, ssh name@ipaddress, .... Things can be working properly and then just quit, Once I was im via skype and lost dns skype continued to work. This has happened in multiple locations on private and public networks. What does not work/fix it: Resetting router changing dns server on computer or router connecting to another network removing the airport interface and adding it back flushing dns The only solution seems to be a restart. A solution to this would be great, but any ideas of this to try would be great. Even a sure way to reproduce this would be useful. Maybe related question: But this is most definitely not true for me. "if I refresh enough -- 3 to 4 times --, it will usually pull up the site. " Here are some tests from terminal. Basically this confirms dns in not functioning vmd17:~ vmd$ ping google.com ping: cannot resolve google.com: Unknown host Trace route to google dns, This works vmd17:~ vmd$ /usr/sbin/traceroute -n -w 2 -q 2 -m 30 8.8.8.8 traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 52 byte packets 1 192.168.1.1 5.195 ms 2.519 ms 2 67.172.136.1 31.881 ms 9.177 ms 3 68.85.107.121 12.168 ms 10.003 ms 4 68.86.103.41 12.021 ms 9.594 ms 5 68.86.91.1 16.712 ms 12.837 ms 6 68.86.86.210 29.951 ms 25.826 ms 7 68.86.87.218 29.554 ms 42.894 ms 8 75.149.231.70 68.271 ms 68.362 ms 9 72.14.233.77 141.178 ms 72.14.233.85 82.553 ms 10 72.14.238.243 83.381 ms 82.811 ms 11 72.14.232.213 194.387 ms 72.14.232.215 84.837 ms 12 209.85.253.145 100.294 ms * 13 8.8.8.8 101.689 ms 89.694 ms 208.67.222.22 is the ip address of opendns dns server vmd17:~ vmd$ dig @208.67.222.222 8.8.8.8 ; <<>> DiG 9.6.0-APPLE-P2 <<>> @208.67.222.222 8.8.8.8 ; (1 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached vmd17:~ vmd$ dig @208.67.222.222 gogle.com vmd17:~ vmd$ dig @208.67.222.222 google.com ; <<>> DiG 9.6.0-APPLE-P2 <<>> @208.67.222.222 google.com ; (1 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached vmd17:~ vmd$ dig @8.8.8.8 google.com ; <<>> DiG 9.6.0-APPLE-P2 <<>> @8.8.8.8 google.com ; (1 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached

  • Windows 7, network connection with no default gateway: any way to change the "Unknown network" statu

    - by e-t172
    Hi, I have a computer running Windows 7 Pro RTM. This computer has two network connections: A Wi-fi connection to the Internet (through a home router) which works just fine. An OpenVPN virtual network connection. More precisely, this is a virtual Ethernet connection which behaves exactly like a physical Ethernet wired connection. My problem is that the "Network and sharing center" shows "Unknown network" for the OpenVPN connection. After some research I found that logical networks (outside a domain) are identified by the MAC address of the default gateway of the connection. Problem is, the OpenVPN connection has no default gateway: it is a private network, so I don't need one... Consequently, the "Unknown network" is always considered public, so the firewall is always in "public mode", which I don't want. Plus, I can't rename "Unknown connection" or anything (which makes sense), so it is kinda ugly. My goal is to define a proper logical network for the OpenVPN connection with the private profile. I know of some workarounds (disable the firewall, modify security policy to make all unknown networks "private") but they're still workarounds. I just want my clients to connect to the VPN without having to disable their firewall settings, without changing global configuration with potential side-effects (the "security policy" solution) and without having to look at an ugly "Unknown connection" in the Network and sharing center. Is there any way I can do this? I tried to check what was going on in the registry (HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList is interesting), but I still didn't find a way to "force" the OpenVPN connection to be assigned to a logical network. Any help would be very appreciated. A related question showed up at Superuser: http://superuser.com/questions/37355/windows-7-cant-identify-network/37422

  • jboss 5.1 mysql connection pooling

    - by boyd4715
    I am using JBOSS 5.1.0.GA, MySQL 5.5 and Hibernate 3.3.1 GA (included with JBOSS) + Spring.

  • Why maximum 1.0 Gbit Ethernet connection an old notebook, and only 100 Mbit on newer faster computer

    - by Sam
    Strange problem about Ethernet speed: recently we bought an i7 core computer running Win7 64 bit with an onboard Gigabit Ethernet controller (Realtek PCIe Gbit Ethernet Family controller). Connecting this new fast pc directly to our brand new ASUS Gigabit Ethernet router via CAT6 cable(!) shows up the adapter status (see picture attached) only 100mbit, while the router is capable of 1000 mbit. More facts: Connecting an 8 year old IBM notebook with gigabit ethernet to the same cable end shows 1.0 Gbit connection in its adapter status. Speedtest.net shows 35 mbit/s down on the new computer Speedtest.net shows 78 mbit/s down on the old rusty IBM notebook. We have an 120 mbit down internet connection, which we we truly receive on another pc (also directly connected to the router) How to get the 1.0 Gbit going in the new pc ?
