  • problems installing mysql and phpmyadmin to localhost

    - by Joel
    Hi guys, I know there have been many similar questions, but as far as I can tell, most of the other people have gotten further than I have... I'm trying to get a WAMP setup happening. I've got PHP and Apache running and talking to each other. PHP is in c:\PHP Apache is in it's default program files folder. mySQL is in it's default install location. I have localhost setup at D:\public_html\ I'm able to navigate to localhost and see html and php files. But I have a simple mySQL test file: <?php // hostname or ip of server (for local testing, localhost should work) $dbServer='localhost'; // username and password to log onto db server $dbUser='root'; $dbPass=''; // name of database $dbName='test'; $link = mysql_connect("$dbServer", "$dbUser", "$dbPass") or die("Could not connect"); print "Connected successfully<br>"; mysql_select_db("$dbName") or die("Could not select database"); print "Database selected successfully<br>"; // close connection mysql_close($link); ?> When I try and open this, I get "could not connect" Now, I haven't even created a database yet, because I can't log into mySQL with phpmyadmin-so I think I've done something wrong in my mySQL install because they aren't talking to each other. I guess my main question is how do I first create a database in mySQL to be sure I have even installed it correctly?

  • Emails not sending from outlook / OWA - Not even hitting the mail queue in exchange

    - by webnoob
    We are having an issue this morning where we can receive external emails but cannot send internal or external ones from Outlook or OWA. If I use: Send-MailMessage –From <[email protected]> –To <[email protected]> –Subject “Test #01”-Body “Just a test message.” –SMTPServer <Server-Name> –Credential <domain\user> the email is sent correctly which makes me think there is a connection issue with OWA and Outlook. However, outlook is reporting as Connected with exchange. I have checked the message tracking in exchange tools and emails sent via outlook and OWA do not appear. Nothing has changed on the server on the weekend so I don't really know where to start debugging this issue. We are using Windows SBS 2011. We only have one send connector which isn't using Smart Hosts and is set to use DNS MX records. Use external DNS is not checked and I can ping google.com etc so doesn't appear to be a DNS issue (plus the email sends from the console anyway). EDIT It appears that users using IMAP can send emails correctly, its only ones that rely on the normal exchange connection type that don't work. EDIT Emails from IMAP are hitting the email queue's where as emails from the normal exchange accounts aren't. EDIT It seems that some of the emails we tried to send yesterday sent at about 1am but now it won't work again..

  • SSH attack CentOS Amazon EC2

    - by user37143
    Hi, I run a few Rightscale CentOS AMI based instances on Amazon EC2. Two months back I found that our SSHD security is compromised( I had added host.allow and host.deny for ssh). So I created new instances and done an IP based ssh that allows only our IPs through AWS Firewall(ec2-authorize) and chnaged the ssh 22 default port to some other port but two days back I found I was not able to login to the server and when I tried on 22 port the ssh got connected and I found that sshd_conf was changed and when I tried to edit sshd_config I found root had no write permission on the file. So I tried a chmod and it said access denied for 'root' user. This is very strange. I checked secure log and history and found nothing informative. I have PHP, Ruby On Rails, Java, Wordpress apps running on these server. This time I did a chkrootkit scan and found nothing. I renamed the /etc/ssh folder and reinstalled openssh through yum. I had faced this on 3 instances on CentOS(5.2, 5.4) I have instances on Debian as well those working fine. Is this a CentOS/Rightscale issue. Guys, what security measures I should take to prevent this. Please support me this is very critical. Thanks

  • Blocking an IP from connecting

    - by Sam W.
    I have a problem with my Apache webserver where there's and IP than connecting to my server, using alot of connection and wont die which eventually making my webserver timeout. The connection will stay as SYN_SENT state if I check using netstat -netapu I even flush my iptables and use the basic rules and it still doesn't work. The IP will get connected when I start my Apache Basic rules that I use: iptables -A INPUT -i lo -j ACCEPT iptables -A INPUT ! -i lo -d 127.0.0.0/8 -j REJECT iptables -A INPUT -s 89.149.244.117 -j REJECT iptables -A OUTPUT -s 89.149.244.117 -j REJECT iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A OUTPUT -j ACCEPT iptables -A INPUT -p tcp --dport 80 -j ACCEPT iptables -A INPUT -p tcp --dport 443 -j ACCEPT iptables -A INPUT -p tcp --dport 21 -j ACCEPT iptables -A INPUT -p icmp -m icmp --icmp-type 8 -j ACCEPT iptables -A INPUT -j REJECT iptables -A FORWARD -j REJECT The bold part is rule in question. Not sure this is related but tcp_syncookies value is 1. Can someone point out my mistake? Is there a way to block it for good. Thank you

  • Periodic internet connection drops

    - by sterlingholt
    My setup is a dsl modem, and a dlink di 524M router. I'm also using a Witopia VPN which runs through OpenVPN. I've been having trouble with the internet connection dropping very frequently. It comes back shortly, without even a router/modem/computer restart. This happens as frequently as every ten minutes. Occasionally (not often) it will last as long as an hour or two without dropping. When it drops, I can get it back almost immediately by clicking Reconnect in the OpenVPN GUI and letting that do it's thing. It's worth noting that I'm in China. Calling support is a bit difficult because of that. Also I don't really understand all of the router's software, although I've got it generally figured out. I've tried a bunch of stuff, attempts to diagnose and/or fix the problem. No success with any of the following: I've power cycled both the modem and the router. I've tried an ethernet connection to the router. I've connected without the VPN. I've disabled IEEE authentication on all connections. I've checked for viruses. I've tried lifting it off the ground so as to prevent overheating.

  • How to clone a HDD and then use the clone with VMware (so that Windows works!)?

    - by Ahmad
    I have a system on which Windows 7 is installed, and I am trying to make a clone of its HDD image, which I then want to use in my main PC with VMware, so that I can boot Windows 7 off the cloned HDD. I used Ultimate Boot CD v5.1.1 with the system whose HDD I wanted to clone, and I cloned it using EaseUs Disk Copy, which comes with Ultimate Boot CD. The source HDD was 250 GB in size which had 3 partitions, while the USB HDD I attached to the system, which was supposed to be the destination/clone HDD, was 320 GB in size. I chose to create an exact replica, and so 250 GB worth of data (partitions, etc.) was copied exactly, and the rest of the space was un-allocated. I now connected this USB HDD to my main PC, fired up VMware Workstation 8 and defined a new Virtual Machine, and chose to boot off the USB HDD. Result is that when Windows is booting (from the cloned HDD inside VMware), I get the blue screen error before I reach the login screen. How can I change my methodology so that Windows even boots from the clone? I can change any tools I use, etc.

  • Green flickering pixels that move with black images

    - by user568458
    Strange question... Occasionally, on my LCD screen, pixels that should be black flicker rapidly and constantly between black and green, about 4 flickers a second. The crazy part is, unlike dead/stuck pixels, they are relative to content on the screen and move with it. For example, I might be looking at a web page with a picture that has lots of black. There might be a couple of green flashing pixels in that black that shouldn't be there. I scroll the page, and the green flickering pixels move with the image. It seems that everyphysical pixel is fine, but somehow something interprets part of the image in a way that causes flickering green... It's not just in a web browser. My first thought was to blame a trolling blogger cunningly uploading an animated gif that simulates a failing pixel... but it happens in a wide range of applications. It seems to occur randomly, other than that it seems to only occur in areas of pure black, and it's always pure 100% green. It happens rarely enough that it's not a big deal, but it's such a strange problem it bugs me. I can't find any info on anything like this. I'm not even sure if it's hardware or software. Any ideas? (windows 7 laptop connected to LCD by DVI to HDMI cable)

  • Mounting any Windows share from OS X 10.7.5 suddenly stopped working

    - by user2169619
    I have problem with mounting Windows network shares from my OS X 10.7.5 - it worked but it stopped and nothing helps and nothing in logs. Here what I get when trying to mount it manually: mount -t smbfs //10.0.0.7/d /tmp/test When doing sniffing with tshark - no packet it sent through and I get immediately return from the command: mount_smbfs: server connection failed: Unknown error: -1 Nothing in /var/log/syslog.log and /var/log/kern.log. The Finder does not work either - it throws an error that something is wrong (in czech thus I'm not sending the message here). I just cannot connect to any network shares. In virtual Windows 7 in Parallels Desktop I can connect successfully, but not within the network share (so the Win7 is behind OS X NAT) but only with its own IP address. The Windows server share is on the same network segment connected through switch. Any advice how to debug and what can be wrong? I spent hours to find solution on Google and here but no-one with this kind of problem and I do not know how to further debug it since there is no meaningful log / trace etc. I can ping 10.0.0.7 and I can connect to FTP server on 10.0.0.7 - the Windows machine (XP) has firewall completely turned off. The problem is that with tshark, I'm not seeing any packet sending to 10.0.0.7 so it's not even trying to reach the server.

  • background jobs and ssh connections

    - by petrelharp
    This question has come up quite a lot (really a lot), but I'm finding the answers to be generally incomplete. The general question is "Why does/doesn't my job get killed when I exit/kill ssh?", and here's what I've found. The first question is: How general is the following information? The following seems to be true for modern Debian linux, but I am missing some bits; and what do others need to know? All child processes, backgrounded or not of a shell opened over an ssh connection are killed with SIGHUP when the ssh connection is closed only if the huponexit option is set: run shopt huponexit to see if this is true. If huponexit is true, then you can use nohup or disown to dissociate the process from the shell so it does not get killed when you exit. If huponexit is false, which is the default on at least some linuxes these days, then backgrounded jobs will not be killed on normal logout. But even if huponexit is false, then if the ssh connection gets killed, or drops (different than normal logout), then backgrounded processes will still get killed. This can be avoided by disown or nohup as in (2). There is some distinction between (a) processes whose parent process is the terminal and (b) processes that have stdin, stdout, or stderr connected to the terminal. I don't know what happens to processes that are (a) and not (b), or vice versa. Final question: How can I avoid behavior (3)? In other words, by default in Debian backgrounded processes run along merrily by themselves after logout but not after the ssh connection is killed. I'd like the same thing to happen to processes regardless of whether the connection was closed normally or killed. Or, is this a bad idea?

  • Remote Desktop Connection issues

    - by stead1984
    I have a server at a remote site, the sites are connected to each other a site-to-site VPN connection using Cisco ASA 5510 firewalls. One end is managed by me, the other managed by the remote location's IT, between the 2 of us is another party who manage and route the connections. Remote desktop has been working fine with no problems then recently I noticed it was working for ONE server over the VPN which it previously had done. All the routes seem fine and I can still ping the remote server and even download files from an FTP site on the remote server.... so the VPN seems fine. Remote Desktop works fine to the remote server within the remote location but not over the VPN. I don't understand why it's stopped working, I originally thought it was a rule in place by the other party but they stress it's not them. The only thing that has changed on the server initiating the RDP connection is that it now runs file services sharing a folder. The source server (remote location) may or may not have had updates applied. Any idea's?

  • Netgear router keeps disconnecting iPhone

    - by DisgruntledGoat
    My old router (Voyager 2091) packed up so I just got a new router - a Netgear N150 model DGN1000. My laptop connects OK wirelessly, but my iPhone 4S is constantly getting "disconnected" - it has perfect wifi signal and is seemingly connected to the router, but no pages load (it says "server cannot be found"). If I disconnect manually ("forget this network") then reconnect, it works fine again for a random amount of time (usually 10-30 minutes) then I get the same problem again. I've done some searching and this appears to be a known problem - there are dozens of forum posts out there lamenting similar connection problems. The only advice I have seen is to set a specific channel under Wireless Settings on the router CP, although every forum post recommends a different channel! 1, 3, 5, 6, 11... I have tried them all for hours at a time and get the exact same problem. The firmware is up to date. Is there an actual solution for this, or do I need to get a different router just to be able to use my iPhone?

  • Window 7 Host does not answer to ping

    - by gencha
    Today I tried printing on a shared printer on one of our homegroup members. Sadly it did not work (printer marked as offline). Shortly after, I noticed I can't even ping the machine that owns the printer (I also can not remotely access it in any other way I've tried). Currently I'm trying to ping the machine from the router both computers are connected to (and my machine in question doesn't answer). I do receive the echo requests (as verified with WireShark). I also added a rule in the Windows Firewall to specifically allow ICMP echo requests, but that didn't change anything. I also tried netsh firewall set icmpsetting 8 enable, but that didn't change anything either. Completely disabling the Windows Firewall has no effect on the issue either. One has to wonder, where does Windows log when and why it ignored any incoming packets? How can I get to the bottom of this? Here are some ways I found to dig deeper into the issue: Enabling logging on the Windows Firewall Enabling Windows Filtering Platform Auditing Both methods at least give more insight into the issue. The plain log file is full of entries like this: 2011-11-11 14:35:27 DROP ICMP 192.168.133.1 192.168.133.128 - - 84 - - - - 8 0 - RECEIVE So the ICMP packets are being dropped as if that was intended. The Event Viewer now gives a little bit more details: The Windows Filtering Platform has blocked a packet. Application Information: Process ID: 4 Application Name: System Network Information: Direction: Inbound Source Address: 192.168.133.1 Source Port: 0 Destination Address: 192.168.133.128 Destination Port: 8 Protocol: 1 Filter Information: Filter Run-Time ID: 214517 Layer Name: Receive/Accept Layer Run-Time ID: 44 This same entry is always repeated with 2 points of information changing: Process ID: 420 Application Name: \device\harddiskvolume2\windows\system32\svchost.exe The service host with the PID 420 is the host for the following services: Windows Audio DHCP Client Windows Event Log HomeGroup Provider TCP/IP NetBIOS Helper Security Center Additionally, there is currently this problem with the same machine: Even though my network is set to be a "Home network", I am unable to create a new homegroup.

  • RD Gateway reporting features/capabilities

    - by Don
    We have just implemented RD Gateway for our own department in preparation for a push to the whole agency for telecommuting. It is all setup and working great, but I was trying to figure out how best to go about monitoring/reporting of users. I see third party software out there that will do it, but is there anything built-in or via powershell/scripting that I could use that would give me a report of the daily activity of users? Something to say, "User A connected at this time, was on for this long, sent/received this much data"? Basically some of the same stuff you can see in event viewer. Ideally I'd like to be able to have this setup so that once a day it emails me with the daily usage for when a supervisor asks about if their person is actually working (or at least online sending and receiving x amount of data), I'll have some metrics to give them. I realize that actual work output is relevant and more of a managerial issue, but I would like to be able to offer as much as I can from my end when asked. Thoughts? Thanks!

  • How to access a port via OpenVpn only

    - by Andy M
    I've set up an openvpn server alongside an apache website that can only be accessed on port 8100 on the same machine. My /etc/openvpn/server.conf file looks like this: port 1194 proto tcp dev tun ca ./easy-rsa2/keys/ca.crt cert ./easy-rsa2/keys/server.crt key ./easy-rsa2/keys/server.key # This file should be kept secret dh ./easy-rsa2/keys/dh1024.pem # Diffie-Hellman parameter server 10.8.0.0 255.255.255.0 ifconfig-pool-persist ipp.txt # make sure clients can still connect to the internet push "redirect-gateway def1 bypass-dhcp" keepalive 10 120 comp-lzo persist-key persist-tun status openvpn-status.log verb 3 Now I tried to let only clients connected to the vpn network access the website on apache via port 8100. So I defined a few iptables rules: #!/bin/sh # My system IP/set ip address of server SERVER_IP="192.168.0.2" # Flushing all rules iptables -F iptables -X # Setting default filter policy iptables -P INPUT DROP iptables -P OUTPUT DROP iptables -P FORWARD DROP # Allow incoming access to port 8100 from OpenVPN 10.8.0.1 iptables -A INPUT -i tun0 -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -o tun0 -p tcp --sport 80 -m state --state ESTABLISHED -j ACCEPT # outgoing http iptables -A OUTPUT -o tun0 -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A INPUT -i tun0 -p tcp --sport 80 -m state --state ESTABLISHED -j ACCEPT Now when I connect to the server from my client computer and try to access the website on 192.168.0.2:8100, my browser can't open it. Will I have to forward traffic from tun0 to eth0? Or is there anything else I'm missing?

  • Move a screen session back to its original PID

    - by cron410
    Installed McMyAdmin (minecraft manager) on Ubuntu 12.04 32 bit. Wrote my own service to start McMyAdmin (.net app running in Mono) in its own screen session, and be able to inject proper McMyAdmin commands into that session with the init.d script. Its been running great! Today, I decided to start installing a Source dedicated server (counterstrike pro mod) I determine its going to be a long download process so I quit the process and fire up a fresh screen session called "source". I paste the command in, but it has a space at the begining and bash complains of ignoring semaphores or some such. I detach and reattach the session. Its sliding like butter. I ctrl+a-d out of the session and start exploring the new folder structure and figure out where I need to place a symbolic link. I go to resume that screen and this is what I see: $screen -r source There are several suitable screens on 20091.source (12/02/12 22:59:53) (Detached) 19972.source (12/02/12 22:57:31) (Detached) 917.minecraft (11/30/12 15:30:37) (Attached) It appears I am connected to the minecraft screen?!?!?! So I attach to the other screens one at a time. minecraft is running in 19972.source and sourceds is running in 20091.source So how the hell did I move the minecraft process to another session called source and my main terminal is now "attached" to the minecraft screen? more: I just used exit to quit the putty session, then logged back in, its still the same. did that 3 more times and now the minecraft screen is gone and everything is acting as it should except, of course, for the session name and start time of the "new" minecraft screen. Should I just submit this as a bug for GNU screen?

  • Tomato/DD-WRT router to act as switch & only NAT some port

    - by fseto
    BACKGROUND: I have a device that must use a real IP address. Currently, my ISP uses DHCP and I can have up to 4 real IP address assigned. However, the cable modem only have 1 ethernet port and it's connected to my router (running Tomato, but can run DD-wrt or other Openwrt if required). Question stems from how I can connect the additional device, requiring a real IP? EASY SOLUTION: would be to get a switch and connect to the CM, Router, and Device. But alas, I want to avoid this route, since: my wiring cabinet in my home is drawing lots of power and heat already Device will be unprotected by any firewall unable to monitor the traffic to/from device. Besides, what would be the FUN in that? =) IDEA: So what I want to do is to configure the router, so that one of the switchport is removed from the normal br0 bridge. Instead, I want to make it behave like a switch on the WAN port. What's the best way of doing this? Should I create another bridge on the WAN & the device port? Can a single port belongs to two bridges? or would I need to create a subinterface first? Would I need a DHCP-relay? Am I expecting too much from my poor cheapie router? +------+ | CM | +--++--+ || +----WAN---------------+ | / \ Router | | BR1?

  • IPC between multiple processes on multiple servers

    - by z8000
    Let's say you have 2 servers each with 8 CPU cores each. The servers each run 8 network services that each host an arbitrary number of long-lived TCP/IP client connections. Clients send messages to the services. The services do something based on the messages, and potentially notify N1 of the clients of state changes. Sure, it sounds like a botnet but it isn't. Consider how IRC works with c2s and s2s connections and s2s message relaying. The servers are in the same data center. The servers can communicate over a private VLAN @1GigE. Messages are < 1KB in size. How would you coordinate which services on which host should receive and relay messages to connected clients for state change messages? There's an infinite number of ways to solve this problem efficiently. AMQP (RabbitMQ, ZeroMQ, etc.) Spread Toolkit N^2 connections between allservices (bad) Heck, even run IRC! ... I'm looking for a solution that: perhaps exploits the fact that there's only a small closed cluster is easy to admin scales well is "dumb" (no weird edge cases) What are your experiences? What do you recommend? Thanks!

  • Debian, 2 NICs load-balancing or agregating with one same gateway

    - by pouney
    Hi, I have one server, with double NICs connected to one switch with the same gateway. Behind the switch we have internet. |Debian| - eth0 - switch - internet - eth1 - same I don't understand how to load-balancing between eth0 and eth1. The inbound/outbound traffic always use eth1. This is the config: # The primary network interface allow-hotplug eth0 auto eth0 iface eth0 inet static address 192.168.248.82 netmask 255.255.255.240 network 192.168.248.80 broadcast 192.168.248.95 gateway 192.168.248.81 allow-hotplug eth1 auto eth1 iface eth1 inet static address 192.168.248.83 netmask 255.255.255.240 network 192.168.248.80 broadcast 192.168.248.95 gateway 192.168.248.81 Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.248.80 0.0.0.0 255.255.255.240 U 0 0 0 eth1 192.168.248.80 0.0.0.0 255.255.255.240 U 0 0 0 eth0 0.0.0.0 192.168.248.81 0.0.0.0 UG 0 0 0 eth1 0.0.0.0 192.168.248.81 0.0.0.0 UG 0 0 0 eth0 Ips aren't real, it's just for the example. Anybody have an idea on correct routing to use eth0 on 192.168.248.82 and eth1 on 192.168.248.83 ? I have many example for multiple gateway but here it's the same. Thanks all. Regards

  • Strange RDP / Remote Desktop problem

    - by John Landheer
    I'll try to be as specific as I can be: Server is running SBS 2008 R2 (with all updates) Server is connected to the internet Server has 2 NIC's, one is disabled Server is running RDP Service (accessible directly from the internet, I know, not as secure as it should be) Computers A and B are on the same local net. Computers A and B are both Windows 7. Users X and Y are both admins on the server Computer A can connect as user X to the server with mstsc Computer A can connect as user Y to the server with mstsc Computer B can connect as user X to the server with mstsc Computer B CANNOT connect as user Y to the server with mstsc! Error that username/password is incorrect. The last point is the problem, I get an authentication error. This used to work flawlessly for the last year. The server and desktops have been rebooted. EDIT: I tried: prefixing domain to the username prefixing the server computer name to the username change the password copy/paste the password from notepad to make sure it was correct I find it very strange.... EDIT: The computers are not on the same subnet as the server. The server is at my hosting provider. All computers as all users can reach the web app that is running on the server.

  • Connecting a laptop to a TV via HDMI

    - by Madmartigan
    I just bought a new Dell XPS17 laptop (Win7) that only has HDMI output. My last 2 laptops had VGA, which I used to connect to my Sony Bravia 32" TV with no issues, but with the HDMI it's been quite a headache. Drivers for display adapters have been updated to the latest versions: Intel(R) HD Graphics Family NVIDIA GeForce GT 550M I went to a store and plugged in to 4 different TVs from different manufacturers. A sales rep and I spent about 30 minutes being baffled by the results (which are the same as my current TV): Extreme buggy behavior in the Nvidia and Windows display/resolution control panel Can not extend or duplicate displays, can only select one Third and fourth output devices "randomly" detected by the Windows control panel Could not get the screen to fit the output (edges cut off on all sides by about a half inch) Resolution and colors less than perfect. Artifacts around text. Display "randomly" cuts out Defaults to TV output only when plugged in Can not change resolution on either device when connected No audio from the TV Plugged in to 3 monitors from different manufacturers: Defaults to duplicated displays when plugged in Everything works perfectly So far, four people have gone through all the settings in the latop with no luck. I had similar, but not exactly matching results with a different laptop. I'm using the Sony Bravia currently at home, but in order to get it to work I have to turn on the laptop, wait until the display shows up on it, close the lid, then cycle through each output channel on the TV until I come back around to the HDMI port again, but still I have the symptoms described above. However: Once in a while, it just works. Sometimes, seemingly randomly, the output fits the screen perfectly. Sometimes the audio comes through the speakers too, but not always. Usually my screen saver "Mystify" will come up with a message that it cannot be displayed due to a limitation of the video card, but then sometimes it works fine. These 3 things seem to be independent of each other and don't always happen together. So, is there any way to get the laptop to output correctly to a TV, or is it just not meant to be?

  • CUPS printer on Vritual Machine can be access via CUPS admin, but not by XP?

    - by SJaguar13
    I have a Zebra label printer connected to a Linux Mint virtual machine. It was set up with CUPS and a Windows XP computer can then print to it via http://192.168.1.76:632/printers/labelprinter. That was all fine and dandy I then hooked up a Fargo Pro L PVC card printer to a Windows XP virtual machine. I had to disconnect the label printer as the server that hosted both virtual machines only has 1 parallel port. Now I plugged in the Zebra again, and it cannot print from the Windows XP computer anymore. If I go to the CUPS admin panel on the Windows XP computer, I can see it, everything looks fine, and I can send it a test page to print which works. If I try to print from Windows, I get an error that the printer is not found/cannot connect to the server. The only other thing that changed was the firewall on the router to allow remote desktop to another computer from outside the network, but all the firewall stuff was for external use. Nothing affected the IP address of the internal network. The Linux Mint VM also had a PDF pritner that was shared with CUPS. That printer is also down. I tried setting up a new CUPS installation on another VM, and when I go to share it with XP, I get the same error. I don't know what to try. It has access, it can get to the admin from that computer, it seems to be up and ready, but when Windows tries to connect, the printer isn't found even though 4 days ago everything was fine. Any ideas?

  • How CPU communicates with HW

    - by b-gen-jack-o-neill
    Good day. I am new here, but I could not find answer to my question using google, so I help I do not violate any rules. So, basically, all I want to ask is, how CPU comminucates with other HW, such as printers, Graphic card, sound card, LAN card etc. I know, that for basic system I/O, you can use BIOS interrupts. INT 10h I believe is for display output. But, what I would like to know is, what actually happens when you execute instruction int 10h. From desription of int instruction, it should jump to routine, which is stored on adress pointed by adress stored in iterrupt table. But how does this routine get into the RAM? Does BIOS save that routines to the RAM? And what actually that routine does? I mean, CPU can only acess RAM, right? So how can now acess some other HW? Is there some special instrucion for it? Or is CPU somehow connected to BIOS, and than BIOS actually does the work? And the last thing, does even OS like Windows or GNU/Linux use BIOS interrupts, or can OS acess HW directly? Thanks.

  • Mac Finder: WD My Passport won't mount

    - by Matt
    I really need your help. I have a WD My Passport 650GB (with Firewire and USB). I'm using it for almost a year now and it always worked fine. While underway I simply plug it in via Firewire - at home I connect it to my Airport Extreme to have it available as a network storage. Today I connected the hd to my macbookpro (via firewire) and NOTHING. The hd is starting (clearly making a sound and the power-indicator is flashing) but it won't appear in Finder. I also tried it with USB - no sign. I ran Disk Utility and tried to repair the disk. At first try I got a red error line saying that something is wrong with the "headers". However the repair completed with a success message saying that everything is ok. I also verified the hd. Also with a success message. I did that a few times again and unplugged it in between. Never got the error with the headers again - it's always completing and saying everything is ok. However I can't mount the drive. That is what Disk Utility is showing. Any ideas on that? I really need the files on that hd. thank you in advance!
