• Sharing files from my Macbook to Windows Desktop

  - by Vahe

  What's the most dependable way to share files and folders on a OS X to Windows (I'm using 7). I've followed this guide: http://support.apple.com/kb/HT1812 However, this method does not seem dependable (Works only some of the time). My Macbook does not always show up under the Network on Windows. On certain occasions, turning off windows file sharing completely (in OS X preferences), restarting my Macbook and turning it back on helps. Is there any reason why this is happening? Is there an alternative method?

• VMware vSwitches and spanning tree

  - by dunxd

  I have two redundant core switches I want to connect to a new vSwitch I am setting up on a VMware ESX host. The switch will have two physical NICs each of which will connect to one of the core switches. The core switches are connected. If this was a physical switch, I would worry about connecting it to both core switches, because this would create a network loop. Do I need to worry about this for a VMware virtual switch? VMware's documentation says it is not possible to connect two vSwitches in a loop, therefore STP is not required. However, I am worried about connecting two physical switches together via a vSwitch.

• Unable to run Django on Mac OS X

  - by cybervaldez

  I'm working with a Django project on my Mac (running Leopard) and I want to show it to my team. I've already passed the neccessary port forwards from my router to my Mac's LAN IP address but it doesn't work. I've also tried running the XAMPP server since that always worked with my Windows XP computer but it still doesn't work. Whenever I type my > it's showing a Page Load Error. Is this possibly an issue with an Mac OS X configuration that I need to setup first to allow my port forwards to get in? It's my first time to do this with Mac, perhaps I need to configure something else in network preferences?

• enable tcp_syncookies even after reboot

  - by Tim

  I'm running Scientific Linux 6.1 and would like to set net.ipv4.tcp_syncookies=1. I've set that in /etc/sysctl.conf and, if I do a sysctl -p then sysctl -q net.ipv4.tcp_syncookies it shows it's properly set. Sadly, if I reboot the machine, and sysctl -q again, it goes back to 0. I've tried to grep around and see if something else is resetting it to 0 during the boot process but haven't turned up anything. I've googled and everything points to sysctl.conf. The only thing I can think of is maybe networking isn't up by the time that file gets read but, honestly, I'm a developer and well beyond my natural skills here:) I'm tempted to just set it directly in /etc/init.d/network but then that feels hackish and so, I thought better of it and I'm here in search of the "right" way to do it. Any pointers?

• Is it possible as an Administrator to gain access to a SQL Server 2008 instance without changing any passwords?

  - by adhocgeek

  I have administrative access on our network, but I don't manage the installation of all servers or software. On some of our machines instances of SQL Server 2008 have been installed which I need to be able to access, but since my account hasn't been explicitly granted a login, I can't get into. Is there a way to get into the database without changing anyone's password (e.g. I could solve this by changing the password of the user who installed the instance, assuming they've set themselves up as admin, and then logging on as them, but I don't want to have to do this).

• How to change the clients and "My Documents" from a SBS2003 server to a new SBS2008 server?

  - by Sanoj

  Today we have a small network with 5 clients and a Windows SBS 2003 as a server. Now have we bought a new server with Windows SBS 2008. How do I easiest: Switch the clients working with the old server, to work with the new server? Is it just to run http://domain/connectcomputer again? Move the data in "My Documents" from the old server to the new server? And finally, is there anything other that I have to think of when changing server? It will be a new clean installation.

• What's an alternative to using public folders (in Outlook)?

  - by Ivo Flipse

  My colleagues abuse our mail servers public folders to store (old) emails so that everyone can read them using IMAP. I'm looking into good alternatives after reading this Tech Republic article: "10 reasons why you should begin phasing out Exchange public folders" The most important thing they need is access to emails from multiple computers without overloading our network. So do you have any suggestions for alternatives? If there's a nice combination with some CRM system it would be interesting too. Note: this doesn't have to be freeware, usability and efficiency are more important. The solution has to be Windows 32 bit only

• peer to peer disk image transmission

  - by JackWu

  Installing linux/windows through pxe works smoothly for me. But downloading images(especially windows) is a headache. Let alone the time, bandwith usage is horrible. And p2p tech comes to my mind. But I have no clue how it works or where to start. Anyone knows how to setup p2p local network, and applies that on image transmission? Any advice, tutorials or experiences will be great. Thanks in advance.

• CentOS box access by name

  - by out_sider

  I intent to develop a centos server with lamp. What I want is connect the server to any kind of home network and access it by http://myserver. I have already successfully set a static ip but I can't seem to ping it by name. If you had to develop a solution with the intent to plug in the box by Ethernet to a router and access it with a browser using the server name what would you do? That's basically what I'd like to know. Thanks in advance

• Which particular file caused "Delayed write failed" error?

  - by user35020

  I sometimes get this error when resuming from hibernation: Delayed Write Failed: Windows was unable to save all the data for the file G:\$Mft. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. I know this is caused because the hard drive (G:, an external USB drive) was (a) plugged in when I hibernated and wasn't ready at wake-up, or (b) I simply forgot to plug it when resuming from hibernation. My question is: is there any way to see which particular file/folder/etc failed to be written? The hard drive functions correctly before and after, so there seems to be no permanent damage. Is there a detailed log someplace or a utility? I've searched but found nothing. Thanks for any help!

• EC2 Windows 2008 VM import Not Working

  - by remack

  I am trying to upload a Windows 2008 SP2 server image to Amazon EC2, but once the process is complete, I can't connect to it. I had ops export a VMDK from our datacenter. The image appeared to have a fixed IP, so I loaded it in VMWare player and enabled DHCP. I uploaded it following amazon's instructions: http://aws.amazon.com/ec2/vmimport/ I start the new instance and try to RDP to the public DNS; connection fails. My two thoughts are: Loading it in VMWare player messed it up somehow, since the instructions say use an ESX image. The image they made me had the wrong network adapter type. The image has an Intel(R) PRO/1000 MT adapter using the E1G60I32.sys driver.

• Server 2008 DHCP some clients not getting IP

  - by AdminAlive

  Today (after turning on the server from an extended power outage) some clients are not able to get IP addresses. Some clients work just fine. Win 7 and XP doesnt seem to matter. I have tried flushing dns, renew, disabling APIPA and even assigned a static IP. Even with the static IP it acts as if it isn't on a network. You can't ping anything. I have also tried resetting the TCPIP stack. The clients that work can ping the DNS and DHCP servers fine. Any suggestions? Thanks

• Change domain password from non-domain computer (AD)

  - by Josh

  I have a domain controller on Windows Server 2008. When I set up my users, I gave them all a dummy password with the "must change on next login" checked. Everyone's machine is all on the same network as the domain controller, but we are not forcing them to join their computers to the domain. The DC has a website which requires the use of domain accounts to access it. How do I tell my users to change their domain passwords without connecting their PC to the domain or making them log in to a machine on the domain? I do not want anything I will have to install on each client to allow them to change their passwords (I have a password expiration policy). Most of these workstations are XP.

• dist-upgrade broke my insatll HELP

  - by diefuchsjagden

  so I ran apt-get update; apt-get dist-upgrade the upgrade failed and I lost the gui, I have an encrypted /home drive. When I run apt-get * (any command) I have all kinds of errors mostly missing depends and thats because apparently my network stack is gone. I have no NIC if I run ifconfig. It doesn't even show up with lspci If I were to do a "clean" install of 10.04 LTS which is what I had on my on my build, will I lose all my data? BTW I was just using Ubuntu's default encryption to manage the encryption using my PSWD as the key so if I were to use the same user name and PSWD would my data be accessible? I can see my data from command line, when or if Xorg does start it just loads a basic window with nothing but a black X in the middle of the screen which I can only assume is my mouse cursor but it doesn't move! Reddit /r/linux had some ideas none of which worked was, no help. And apparently /r/ubuntu is full of jerks because all they did was ridicule me. If I can get my install back I probably will be switching back to either Slackware or Gentoo. The Ubuntu forums were of no help they had the same suggestion as /r/linux. I am about to just run my back up script to my back up drives and nuke everything else but I'd rather not.

• RAID 1 in ubuntu 12.04

  - by Bavly Hanna

  Right now I have a small file server to which I have loaded ubuntu 12.04 desktop on a small 160gb harddrive. This harddrive is the primary drive from which the OS boots. I want to move all my data to my file server so it can be shared on the network (contain in 2x2TB harddrives in my desktop. The 2TB drivers are in raid 1 (hardware). I simply want to move them to the file server and set it up so that they are in software raid 1. If at all possible I'd like to be able to do this without losing any info on the drives. I've searched around and the guides i find describe raiding drives for boot driver, but these wouldn't be boot drives just regular storage drives. If someone could tell me how to perform this or point me in the right direction it would be much appreciated.

• How can I set up disk quotas on a remote server in a Samba environment?

  - by graf_ignotiev

  I've been working with an install of Ubuntu 8.04 and Samba. I'm trying to set up user disk space quotas for our shared drive. That is, each user will have their own folder on our Network Attached Storage (NAS) that has a size limit. I can successfully mount the shared drive, but I can't figure out how to set quotas on it (I think smbcquota might work, but I'm not sure). It's been suggested to me to give each user a share on the shared drive or to use NFS. Unfortunately, neither option works for my purposes. Does anyone know how I could give users a quota on my NAS?

• LAN full of public ipv4 addresses - How to filter it?

  - by sparc86

  The answer to my question maybe is not that hard but anyways, I do not know what to do. So, I just got in a new job in a Univerisity and I found out that the network (the LAN) is full of public IP addresses. Seriously, the whole LAN (probably more than 150 hosts) has it' own internet IP address and I don't know how to manage it. I have a very good experience using iptables (Linux firewall) in a NAT'ed environment. But then how should I proceed in an environment where all my LAN is working with a bunch of public IP addresses? Should I just use the "forward" rules and ignore the NAT rules or is there any other issue in such environment which I should take care? Can I add a firewall between the router and the LAN in order to produce packet filtering for these public IP addresses in my LAN or will this just not work? Thanks!

• Upgraded to Mountain Lion, now 127.0.0.1 is not resolving

  - by Shanimal

  I used to be able to type 127.0.0.1 (or my network IP 10.10.53.32) and it would resolve to my "default" virtual host. 127.0.0.1/~Shanimal and shanimal.dev both resolve to their appropriate folders. localhost and 127.0.0.1 give me a 404 - "Not Found The requested URL / was not found on this server." Basically, my "It works!" screen no longer works. /private/etc/apache2/Shanimal.conf: <Directory "/Users/Shanimal/Sites/_www"> Options Indexes Multiviews AllowOverride AuthConfig Limit Order allow,deny Allow from all </Directory> hosts: 127.0.0.1 localhost 127.0.0.1 shanimal.dev

• How can I move authorized applications between google accounts?

  - by zoopp

  I'm looking into creating an email address with a professional name on gmail and due to the fact that I can't change my current one I have to create new google account. Among some things which which need to be patched (eg. forwarding email to the new address until every other account's email contact address is changed etc.) I came across authorized applications. If I am to use exclusively the new email address I have to somehow move my authorized applications as well since if I am to eventually delete my old account I will lose access to my current profiles created by those applications (eg. the stackexchange network, youtube etc). How can this move be accomplished?

• Prioritize file sharing capabilities in Windows Server 2008

  - by cmbrnt

  I've got a server running Windows Server 2008, and use it mainly for sharing files throughout the domain from a number of disks. It's running on VMware ESXi 4.0, in case that matters. My problem is that when I log in to the server to check user permissions etc, the access speed the files on the remote disks almost grinds to a halt. I havn't been able to measure the speeds, but I would guess it slows down to about 100kB/s as soon as I log in. This is on a gigabit network and the problems are equal for all users, even the ones connected to the same switch as the server. I've assigned 2 GB RAM to the server, and reserved it 1,5Ghz processor power. I don't have to do anything special on the server for this halt to occur. How can I make sure file sharing is prioritized on the server, so no matter what applications I'm using it will always make sure file sharing works properly? Could this be a VMware issue?

• /etc/hosts file for a multi-homed, multi-domain machine?

  - by threecheeseopera

  I have a server (debian) with two network interfaces that I would like to host multiple services and domains on; it is not entirely clear to me how the hosts file should be set up. Example: eth0, bound to WAN interface 1.2.3.4: mail.example.com www.example.com eth0:1, bound to WAN interface 1.2.3.5: www.other-domain.com eth1, bound to LAN 192.168.1.123: some-clever-hostname What should my hosts file look like? (including localhost,localhost.localdomain, etc.) Should I use DNS for some of these entries? Which ones? Thanks!

• What is the standard term for my role?

  - by sigil

  I'm doing work that involves writing code and managing developers in a "special projects" division of a large company. I'd like to define my role better and figure out if there's an industry standard term for what I do, so that it will be easier for me to research best practices and work on a career path What I do all day: A macro that connects an Excel sheet to an Access database is acting funny; I get called in to figure out what's happening and debug it. Someone needs data extracted from a bunch of files on Sharepoint. I figure out a client-side solution because I'm not authorized to do anything server-side and getting IT to do anything would take several months and need a business case. A manager wants a new data entry tool for their team. I interview the manager and team members to work out the functional requirements, then design/develop/test the application. Someone needs a VBA script to crunch some data for their presentation that's due in two hours. I drop everything I'm doing to hack out a quick script and run the analysis, without much in the way of testing. A developer has been hired to build a database for one of the teams, since I'm working on too many different things and don't have time to take this project on in the timeframe required. I direct his work and push him to meet certain deadlines, interview stakeholders to get more info that will help him figure out how to build the necessary forms, and modify the functional requirements of the database to fit in the timeframe. Someone wants to load a set of data into a GIS system and set up an ongoing refresh and reporting of this data set. I facilitate the conversation between the GIS developers and the owners of this data set, and design a demo application as proof of concept. It's kind of an "all-purpose programming and IT management" position, but it's not officially IT because the company has an actual IT department with a rigorously defined system of submitting requests, developing code, and managing projects. What I do, I guess, is more of a handyman job, where stuff falls to me because I'm the geekiest one in the room. Is there a standard term in the software world for what I do?

• Windows Media Player 11 fails to authenticate with proxy (ISA)

  - by Ed Manet

  We have some users who need to use a 3rd party site that embeds Windows Media Player streaming video into a web page. Our users go through an ISA proxy server to connect to the Internet. The browser has no problems accessing the site through the proxy. When Media Player loads, we get prompted for network credentials, but the authentication fails. If we set up Internet Explorer 8 to not use the proxy, Media Player has no problem. Media Player is configured to use the RTSP/TCP and HTTP protocols, but not the RTSP/UDP protocol. Is this necessary? Is there a registry key I can use to enable it? Is this more of a proxy server issue? The proxy guy says it's a desktop issue.

• Destination host unreachable

  - by user1010101

  I have 2 router connected to 1 switch which contains two vlans, 1 router has the ip table of vlan1 and the other router have the ip table of vlan2 I have trunked both router cable to the switch. I have set 1 ip table per router which correspond to the ip address of the PC that have this router address as a gateway. When I ping from 192.168.100.2 to 192.168.200.2 it tells me that destination host is unreachable and the message is from the router 192.168.100.1. So I guess router for 192.168.100.x does not see the router for 192.168.200.x , right ? Or am I wrong ? What are good troubleshooting steps ? http://i.imgur.com/b94Ir.png is the representation of the network, i cannot post image since im not reputated enough.
