• Single m0n0wall - Two LAN Subnets - How To Setup

  - by SnAzBaZ

  I have two LAN subnets that I need to link together they are 192.168.4.0/24 and 192.168.5.0/24 There is a m0n0wall running on 192.168.4.1. It's LAN connection goes out to our network switch, and it's WAN port goes out to our ADSL modem. WAN is connected via PPPoE. The 192.168.4.0 subnet contains all of our office workstations. The 192.168.5.0 subnet contains development servers and test machines that need to obtain internet access and be "managed" by computers on the 192.168.4.0 subnet, but need to be on their own subnet as well. I have a Draytek 2820N configured on 192.168.5.1 with it's WAN2 port configured as 192.168.4.25 and a default gateway of 192.168.4.1. Machines on the 5.0 subnet can connect to the internet via the m0n0wall just fine. I configured a static route on the m0n0wall LAN interface, Network 192.168.5.0/24 and Gateway 192.168.4.25. Machines on the 5.0 subnet can ping machines on the 4.0 network but the reverse does not work. I configured a new firewall rule on the m0n0wall that allows any traffic on the LAN interface with a source IP of 192.168.4.25 to be allowed. The DrayTek firewall is currently configured to pass all traffic regardless. When I try to ping a machine in the 5.0 subnet from 4.0 I see this in my m0n0wall log: BLOCK 14:45:27.888157 LAN 192.168.4.25 192.168.4.37, type echoreply/0 ICMP So the reply is being sent from the 5.0 subnet but is not being allowed to reach my workstation because the firewall is blocking it. Why is the firewall blocking it ? I hope the explanation of my network is clear, please ask if you require further clarification. Thank you.

• CIFS Mounting Permissions

  - by malco

  I have an issue that I;m going round in circles with, I hope you can help. The Set up: Server 1 (CIFS Client) - CentOS 6.3 AD integrated uing Samba/Winbind & idmap_ad Server 2 (CIFS Server) - CentOS 6.3 AD integrated uing Samba/Winbind & idmap_ad All users (apart from root) are AD authenticated and this, including groups, etc works happily. What's working: I have created a share on Server 2: [share2] path = /srv/samba/share2 writeable = yes Permissions on the share: drwxrwx---. 2 root domain users 4096 Oct 12 09:21 share2 I can log into a Windows machine as user5 (member of domain users) and everything works as it should, for example: If I create a file it shows the correct permissions and attributes on both the MS and the Linux sides. Where I Fall Down: I mount the share on Server 1 using: # mount //server2/share2 /mnt/share2/ -o username=cifsmount,password=blah,domain=blah Or using fstab: //server2/share2 /mnt/share2 cifs credentials=/blah/.creds 0 0 This mounts fine, but.... If I log su, or log onto server 1 as a normal user (say user5) and try to create a file I get: #touch test touch test touch: cannot touch `test': Permission denied Then if I check the folder the file was created but as the cifsmount user: -rw-r--r--. 1 cifsmount domain users 0 Oct 12 09:21 test I can rename, delete, move or copy stuff around as user5, I just can't create anything, what am I doing wrong? I'm guessing it's something to do with the mount action as when I log onto server2 as user5 and access the folder locally it all works as it should. Can anyone point me in the right direction?

• SQL Server 2008 login problem with ASP.NET application: Failed to open the explicitly specified database

  - by eulerfx

  I am running SQL Server 2008 Express Edition on Windows Server 2008 with an ASP.NET application which must access the server. The ASP.NET application is associated with an application pool that runs on the NetworkService account. This account in turn has a Login and User record on SQL Server in the required database. When I attempt to run the ASP.NET website I get a blank page and when viewed in the error log, I seem to be getting this information event record: Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. Reason: Failed to open the explicitly specified database. [CLIENT: myLocalMachine] The connection string has Trusted_Connection=True; and the required database specified. When I explicitly specify the user name and password I get another login error stating the password is incorrect, even though the same un/pw combination works through SQL Server Management studio. The NETWORK SERVICE account seems to have all the required privileges for the database. Also, I made a test ASP.NET website project which does a simple select from a table in that database, and using the same config file I am not getting the error and it seems to work. Is it something to do with trust levels then, because the original ASP.NET web app references various DLLs including open source libraries. Also, the application does not seem to be able to write to the event log itself, throwing a security exception, even though everything in the config files, including machine.config states the app is in full trust.

• Strange Internet Connection issues

  - by Nodren

  I'm attempting to troubleshoot problems with a laptop computer(HP 8510w) while it's connected to a server of mine via Remote Desktop. I double checked all the settings on the win2k3 server for remote desktop to verify that remote desktop isn't what's causing the disconnect issues, and other people using different computers/laptops can all connect to remote desktop correctly with no issues. These problems happen specifically when the laptop is connected via wifi(several different wifi sources, so it's not an ISP issue) as well as connected via a Verizon data card. However there's no network downtime when the laptop is resting in the docking station and plugged into the network with the remote desktop server. These problems have also only recently occurred since a recent hard drive failure in which a new hard drive was purchased and the laptop had a fresh install of windows xp professional. There's no special software used on this machine, just office 2003. So my question is, what could cause two types of internet access to fail while other types do not? If it is infact related to the win2k3 server, why is this particular laptop getting disconnected when others are not and are all on at the same time?

• Windows 7 ignores F6/F8 and will not boot

  - by P.Brian.Mackey

  I have a work PC with sophos safeguard encryption on it. Windows failed to start. When I bootup I receive an error saying a recent hardware or software change might be the cause. File: \Boot\BCD Status: 0xc0000098 Info: The windows boot configuration data file does not contain a valid OS entry. This began after the PC forced me to run a system recovery. My machine had powered down improperly (power outage?) and simply would not respond to my keyboard input to cancel the option to scan my system. After the scan "repaired" a boot file, my system crashed. Now it tells me I can insert my windows 7 disk and run recovery. I can't simply do this because of Safeguard. The system recovery can't see my encrypted drive. I tried hitting F2 to manually login to Safeguard and then selected the option to boot from media. The computer prompts me to hit any key to boot from disk...which I do, but once again it is not reading my keyboard input. I can't get F8/F6 to bypass startup files and get me to a command prompt like the old days. If I could get to a command prompt I might could recover the file windows jacked up from its backup location...though I may need to use the windows recovery disk UI to do this..??? In the past I've been able to slap in a PS/2 keyboard when the USB keyboards stop responding like this. I have no PS/2 keyboard available. Anyone have any idea how I can undo the damage windows system recovery has done with safeguard installed?

• Roaming Profiles & Redirected Folders - storage consumption? offline files and caching?

  - by Ben Swinburne

  I understand the concepts of both roaming profiles and folder redirection and have used both separately before. I am about to set up a network from scratch and would ideally like to use both for the following reasons primarily Roaming profiles allow users to log on to any machine and have their profile Redirected profiles allow users to have their My Documents and Desktop etc backed up without the need to log off at the end of the day. The servers can run their backups overnight and there are no missing files due to the user not logging off. Redirected profiles largely alleviate the slow log in times caused by large profiles. My question is if some of the folders are redirected and therefore not part of the roaming profile what happens on machines which truly roam (i.e. laptops)? If there's offline files or a cache does this mean that the problem whereby a user has to log off comes back? By having them both enabled, is there any duplication i.e. if I have a users$ share and a profiles$ share would I have Desktop twice for example?

• Chrome pop-up blocker fail?

  - by Count Zero

  I have this problem since just a few days. I've been a heavy Chrome user for several years, but it never happened before: Sometimes absolutely uncalled for pop-ups appear, when I click something absolutely legit. It seems to happen at a very precise rate of two pop-ups every hour or so. The pop-ups are not very varied, it seems to be a fixed set of some 4-5 ads. At first I thought I caught some malware, but after a full scan with Malwarebytes Anti-Malware, I found absolutely nothing. In addition the problem exists only with Chrome. When I use Firefox, this never ever happens. What is even more puzzling is that it happens on both of my rigs and started on the same day. I have a removable storage that I dock to both of them and access one machine from the other via RDP, but still... It seems this is a problem that others face too. See this Google forum and here. Could it be that the latest Chrome build is just acting up? (Just in case it matters: I run Chrome version 24.0.1312.57 m on Win 7.)

• Error sending email to alias with Postfix

  - by Burning the Codeigniter

  I'm on Ubuntu 11.04 64bit. I'm trying to set up Postfix on my VPS, which has been configured but when I send an email to an alias e.g. [email protected] it will send it to [email protected]. Now when I sent the email from my GMail account, I got this returned: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error.

• What is it safe to let Revo Uninstaller cleanup leftovers?

  - by msorens

  I have been a user of Revo Uninstaller (free) for sometime and find it does a very good cleanup job with typical applications. Today I wanted to clean up my machine a bit more so I proceeded to remove Visual Studio 2005 with Revo Uninstaller. The VS installer removed the app with no issues, then Revo reported about 20,000 leftover registry keys. I am used to basically just see Arpcache and Muicache... since I am not a registry expert I had no clue about most of the 20,000 listed. So I backed up the registry then let Revo remove the 20,000. It next reported about 1500 leftover files which included my Microsoft Office applications(!) that I knew it should not be touching. So I did not delete any files with Revo. Suspecting that some of the removed keys were also Office-related, I tried to open Word and Excel, both of which knew something was up, as the installer kicked in (albeit just briefly) for each of them. At this point, since I knew there were issues, I just restored the registry and I am now (seemingly) running OK. My question, then: When is it safe to trust Revo Uninstaller? As a seasoned software professional, my own answer to this would be the obvious "When the keys it reports are something you understand and know are safe to delete" but then that makes Revo of little use except to registry experts, does it not...?

• How to have PHP and mod_wsgi python app on the same domain?

  - by Lazik

  I am using apache with mod_wsgi (python3) on ubuntu 12.04. I have a python app (bottle) which is at www.mysite.com/ In my python app I have routes like www.mysite.com/abbb?q=blab I would like a path www.mysite.com/forum to resolve to a php app (simple machine forums) Ideally I would like to use apache to handle the forum part and pass it to php (instead of coding it in the python app). Don't know if it's possible. I'm new to this, I have read https://code.google.com/p/modwsgi/wiki/ConfigurationGuidelines#The_Apache_Alias_Directive but I don't understand how to use it. Here is my apache conf for the mod_wsgi app, I don't know how to specify the PHP portion. <VirtualHost *:80> ServerName www.ex.com ServerAlias ex.com *.ex.com RewriteEngine On RewriteCond %{HTTP_HOST} !^www\.

• Hyper-V with multiple physical networks

  - by Yaman

  I have Hyper-V on my laptop with a wireless and Ethernet card, sometimes I connect using wireless card, and sometimes using the Ethernet cable. I am trying to configure Hyper-v to work always with internet provided to virtual machine. I have tried to create 2 virtual switches, one external to the Wireless network card, and the other one external to the Ethernet card. What happens is that the wireless network creates a bridge object in the network and sharing center\Network connections of windows 8, while the Ethernet does not. Unfortunately, they do not work together as external, i have to set the connected one to external and the other one as external, I also have to go to the properties of the bridge and virtual Ethernet properties to uncheck and check some components like: Client for Microsoft Networks Deterministic Network Enhancer VMWare Bridge Protocol QoS Packet Scheduler File and Printer Sharing for Microsoft Networks In order to make things work. Sometimes I keep the wireless network switch external, and go to another location (another wireless network), and it disconnects, i have to reconfigure the switches. Is there a way to do the configuration once and remain working wherever I connect, whether its Wireless or Ethernet and on any network with DHCP?

• Roundcube "Server Error (OK!)": Lists no messages but can get messages according to the log file

  - by thonixx

  In my server setup there are three virtual machines. One windows machine, an Ubuntu Server 11.10 and a Debian Squeeze mailserver. On the Ubuntu system I have Roundcube installed and I want to connect to the virtual mail server. What's the problem After login into Roundcube it says "Server Error (OK!)" and lists no messages. More information On the Ubuntu server there is no error in any log file (even Roundcubes log files). In the imap log file there you can see Roundcube is able to fetch all imap messages (I can see them in the imap log file created by Roundcube). And on the side of the mail server there are no error messages too. The test connection at the end of the configuration of Roundcube works too, there is a "success" notification. Even the basic login at Roundcube login dialog works without any error message. Roundcube log file you can look here for the log file: http://fixee.org/paste/wxg36eh/ So does anyone know what's wrong with Roundcube?

• Why do manufacturers not show all hardware power usage?

  - by Drew

  I find it slightly more difficult to build a computer when I do not know how much power is needed for a component. When selecting a power supply for a computer, it is difficult to know how large of one to get. You don't want to go too large for cost reasons and circuit reasons, but you don't want to go too low and not be able to properly use every component. For instance, a graphics card might say "Minimum of a 500 Watt power supply. (Minimum recommended power supply with +12 Volt current rating of 30 Amps.)" But it really needs 360W (12V * 30A). So why don't they just say "Uses 360W max and xxxW peak"? Processors, I have noticed are good at reporting their power usage, but aside from processors and sometimes graphics cards, power usage is easily found. What is the power consumed by the Blu-ray / DVD drives? By the HDDs/SSDs? By the Mobo? etc. Why are these questions not easily answered when building a machine?

• Linux virtualization choices with graphic acceleration / video card support

  - by Urbn

  I am in the process of building a new desktop machine for work and fun. I am looking to run a undecided flavor of Linux (guessing Ubuntu) as my primary OS and several Windows installs with a Windows 7 install for .net development and gaming as virtualized environments. From my previous experiences with virtualization software in Linux I was never able to find an application that offered descent video card support / graphic acceleration etc. to be capable of playing any games within one of the virtualized environments. And since I will be investing quite a bit of money into this system for gaming I would naturally want to find the best option available to achieve this setup. So Onto my question: Is there any virtualization software available for Linux that has full video card support, graphic acceleration and capable of taking advantage of everything the video cards have to offer within the virtualized environments? Or am I stuck with running Windows 7 as my primary OS and using virtualization for Linux and the other OS's? Also I have no preference on open/closed source and price range would be up to $175.00 to support at least 3 virtualized environments.

• Best way to troubleshoot intermittent network outages?

  - by Ben Scheirman

  We have a Comcast 50/10 line into our office. We keep seeing very short but sometimes frequent drops in our internet service. It's enough to kick you off of skype and stop any websites from loading, which is obviously affecting our productivity. We've tried 4 different routers, we've tried moving everyone off of wireless and onto wired via a switch and so far nothing has helped. Right now we're on a Cisco SB WRP400-G1 router. Attached to the router is a 16 port switch going to the ports in all of the offices. We've moved to OpenDNS in the case that it was the comcast DNS servers going down. Today we tried putting the modem, router, and switch on a UPS to make sure it wasn't power fluctuations that was causing it. Every time we call Comcast, by the time they are here the internet is working fine. I'd like to somehow prove that the problem is with Comcast, so if that means plugging in a machine directly into their router and collecting data all day, I'm up for that. I just want to hear ideas on what tools to run and how to collect this data. I could just continuously ping google.com all day long but I'm not sure how valuable that data would be. Thoughts?

• Regarding AD Domain controllers and remote branch offices

  - by Alex

  We have central HQ building and a lot of small branch offices connecting via VPN and want to implement AD (If you can believe we still haven't). We want everyone to log in using domain accounts and be policed centrally. We are OK with having a RODC in a branch office with like 10 computers. But we have these small branches with two to four PCs only. Some of these branches connect to HQ via IPSec site-to-site VPN, some via remote access (client-based) VPN. So there is no problem with ones that have local RODC or connecting to HQ DCs via VPN router. But how about small branches? We don't really want to set up a machine there, neither we want to invest into Windows Server licenses or fancy network equipment. Also, the problem is that we cannot access HQ DCs via VPN because we are not logged in and connected to HQ internal network yet, so DCs aren't reachable. What is typically done in that situation if it is needed to have central management over policies on those PCs? Or is it better to let 'em loose and use local policies and accounts in this situation?

• How can I setup a Proxy I can sniff traffic from using an ESX vswitch in promiscuous mode?

  - by sandroid

  I have a pretty specific requirement, detailed below. Here's what I'm not looking for help for, to keep things tidy and on topic: How to configure a standard proxy Any ESX setup required to facilitate traffic sniffing How to sniff traffic Any changes in design (my scope limits me) I need to setup a test environment for a network-sniffing based HTTP app monitoring tool, and I need to troubleshoot a client issue but he only has a prod network, so making changes to the config on client's system "just to try" is costly. The goal here is to create a similar system in my lab, and hit the client's webapp and redirect my traffic - using a proxy - into the lab environment. The reason I want to use a proxy is so that only this specific traffic is redirected for all to see, and not all my web traffic (like my visits to serverfault :P). Everything will run inside an ESX 4.1 machine. In there, there is a traffic collection vswitch in promiscuous mode that is not on the local network for security reasons. The VM containing our listening agent is connected to this vswitch. On the same ESX host, I will setup a basic linux server and install a proxy (either apache + mod_proxy or squid, doesn't matter). I'm looking for ideas on how to deploy this for my needs so I can then figure out how to set it up accordingly. Some ideas I've had were to setup two proxies, and have them talk to eachother through this vswitch in promiscuous mode, but it seems like alot of work. Another idea is a dual-homed proxy, but I've never seen/done that before so I'm not sure how doable it is for what I'd like. I am OK with setting up a second vswitch in promiscuous mode to facilitate this if need be, but I cannot put the vswitch on the lan (which is used so my browser would communicate with the proxy) in promiscuous mode. Any ideas are welcome.

• running a command as root with /bin/su and without gives different results

  - by n00bInCpp

  Some background: I have a machine with SLES 11 installed. I am running a bash script that one of its lines is /bin/su $USER -c SOME_CMD. Unfortunately, the SOME_CMD that comes after the -c keeps failing, no matter if USER=root or any different user. However, if /bin/su $USER -c part is omitted then everything runs smoothly. Moreover, I have run the script on RHEL5 and it worked fine. Anyway, my question is why does it happen? If it is a permissions problems then why when I run this as root with /bin/su and without I get different results? P.S. apologize if somebody else has asked it before, I have done many googling and got nothing that satisfies. Thanks in advance, n00bInCpp EDIT Okay, I figured it out, I hope so. Instead of running /bin/su I used /user/bin/sudo -u $MY_USER_1 MY_ENV_VAR="/home/user1" SOME_CMD. I don't understand why I have to use sudo, though. I am used to run a command as a different user using su and not worrying about permissions problems, but I guess it doesn't work like that on SLES 11/SuSE. Anyhow, thanks to everyone who wanted to or helped me.

• Samba access works with IP address only

  - by Sebastian Rittau

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

  Small business server 2011 standard - applications randomly closing for remote desktop users I have an issue where when you are connected through remote desktop (doesn't matter whether you have administrative rights or not). What happens: Any application that you run (outlook, word, excel, notepad, cmd etc..) the application will randomly crash and produce an error as such: Faulting application name: EXCEL.EXE, version: 14.0.6112.5000, time stamp: 0x4e9b2b30 Faulting module name: ieframe.dll, version: 8.0.7600.16930, time stamp: 0x4eeb0187 Exception code: 0xc0000005 Fault offset: 0x0000000000131e03 Faulting process id: 0x3d4c Faulting application start time: 0x01cecf3491388e43 Faulting application path: C:\Program Files\Microsoft Office\Office14\EXCEL.EXE Faulting module path: C:\Windows\System32\ieframe.dll Report Id: 1c06abd4-3b2b-11e3-bd8d-001999b270e9 I noticed the ieframe.dll, but its not constant for every application that crashes, e.g.: Faulting application name: OUTLOOK.EXE, version: 14.0.6109.5005, time stamp: 0x4e79b6c0 Faulting module name: PSTOREC.DLL_unloaded, version: 0.0.0.0, time stamp: 0x4a5be02a Exception code: 0xc0000005 Fault offset: 0x000007fef39c7158 Faulting process id: 0x43f8 Faulting application start time: 0x01cecf33fe5eec26 Faulting application path: C:\Program Files\Microsoft Office\Office14\OUTLOOK.EXE Faulting module path: PSTOREC.DLL Report Id: 0c0f5934-3b2b-11e3-bd8d-001999b270e9 I am unable to perform a sfc /scannow command due to the cmd.exe crashing as well.. I have performed a virus scan on the server which did originally pick up 5 viruses: riskware.tool.ck -> File riskware.tool.ck - > Memory Process trojan.agent.bdavgen -> File trojan.agent -> File HiJack.comsysapp -> Registry Data But after removing these and rebooting the machine we have had no luck Has anyone else ever come across this issue before? Also to elaborate it is happening as frequently as every minute.

• Performance tweaks and upgrades for VMWare Server 2

  - by sjohnston

  Our software department has a server running VMWare Server 2. We typically have 8-10 VMs running as test environments (Win XP and Server 08) for various versions of our software, and one VM that is used as a build server (Win XP). The host is running Server 2003 R2. It has 32GB RAM, 8 core Xeon 3.16GHz CPU, one disk for host OS and two raid disks for VMs. The majority of the time, this setup behaves very well and there are no complaints. Other times, the VMs can be very laggy. This is sometimes, but not always, correlated to heavy load on the build server. I'm a software developer, not an IT pro, but it seems to me that this machine should be beefy enough to handle this many VMs. Is this occasional performance hit likely just because we're hitting the limits of the hardware, or should I be looking for another culprit? From what I've read, I'm guessing if there's a bottleneck, it's probably disk I/O with all these VMs running off two disks (especially the build server). Would spreading the VMs over more disks, and/or switching to SSDs give us a significant performance boost? Other things I've read may increase performance: single virtual processor per VM removing/disabling unused virtual hardware preallocated disk space not using snapshots setting a reserved memory limit on the host and disabling VM memory swapping Can anyone confirm or deny if any of these improve performance? What other good tweaks have I missed?

• Can't Configure IBM 8275-416 Switch Via Serial

  - by Sean M

  I am attempting to configure an IBM 8275-416 switch (I found a manual here) via serial connection. However, when I connect with HyperTerminal, the output contains a lot of garbage characters. It's pretty much unusable, because there's enough layout-breaking text-gunk that it's very difficult to determine what's actually being displayed. . I was able to reset the switch to factory defaults via the terminal interface, so I know that it's not entirely broken. It also performs basic functions all right (i.e., you plug in clients and Ethernet cables - they can connect to clients plugged into other ports) - but I'd like it to do more than that (VLANs yay). I don't know if its in-band UI is operational or not, because I can't get the terminal interface to behave well enough to properly turn on the web/SNMP UI. So that's not available. Things I've tried: - Changing the encoding: HyperTerminal lets me choose between Standard JIS and Shift-JIS. Neither setting fixes the issue. - Checking emulation settings: The manual demands VT100, 19200 baud, 8 data bits, and such: I have faithfully applied these settings, both in HyperTerminal's settings and in the properties of the COM1 port in Device Manager (connecting from a Windows machine). - Restoring to factory defaults: See above. Things that it could be, but that seem unlikely: - Cabling: Couldn't find a proper null-modem cable, so used two 232-to-RJ45 adapters. But if it was a problem with the cable, wouldn't it be more likely to not connect or do input at all, rather than just garble the text? Since I was actually able to perform the reset-to-factory defaults operation, I don't think it's this. - Device as a whole broken: It is a decade and change old, so it's possible that it's just dying slowly. Again, though, it seems like there would be more symptoms than just garbled text in the terminal. What else can I try to get a sane interface to this switch?

• Default Critique branch office setup: VPNTunnel->HQ, subnets for VOIP/PC, + several Q's

  - by CHickenTaragon

  We're setting up a new branch office. * ~10 users. * Each user has a VOIP phone provided by a hosted solution. * Users need access to resources on HQ (located in another state), so setting up VPN tunnel * HQ only supports certain Cisco/Juniper devices. VOIP provider only supports SonicWall, so current plan is to have two routers w/ separate subnets for VOIP vs. PC traffic. * PC's will plug into pass-thru Ethernet jacks on the VOIP phones, but the phones vs. PC's will point to different subnets. * Cable Modem is 50Mbps / 5Mbps DOCSIS 3.0 business line w/ 5 static IP's. * Each of the 2 subnets will map to one of the 5 public IP's. * May or may not also need to support a VPN tunnel with a second branch office because of a file server they have there that some in the new office use. I'm pushing to have them move the files to a server on the HQ's network so we don't have to worry about setting up an additional tunnel. Questions: Do you foresee any issues with the below set-up? Router recommendations by HQ IT staff: Cisco Router 2811, or Juniper SSG5 or SSG20. Any recommendations about these routers? We need Wi-Fi too – looks like the above routers have models that support this, any reason not to use this? Users need to be able to work from home. If so, how is authentication handled? Right now we use AD credentials for the HQ's domain, but we currently don't plan to have an AD system in the new location since it's only 10 users. We can't tie the authentication system from the new location's router to the AD system of the HQ. All the PC's that will be in the new location are currently in the existing office that is closing down, and are already joined to the domain of the HQ. Please confirm: this + the VPN tunnel will be sufficient for them to connect to authenticated resources on the HQ's network from the new location, correct? Mainly SQL servers and file servers, and a few remote desktop sessions. I'm sure I'll have some more questions, but can't think of them right now.

• Outlook / Gmail 'too many simultaneous connections' error

  - by sam

  I'm just setting up Outlook for Mac, and I'm trying to add a Google Apps application for business email (Gmail). I've set it up correctly (same details worked in Mac mail). But I keep getting two errors, either or just a error asking for the username and password again. Just to confirm the user name and password are correct, although when I go into menu command Tools - Account and look in the password field for that account it's blank. But if I just click cancel on the popup asking for my username password it just continues to get mail in the background for about 30 seconds, before again asking again for the password, or showing the above error which I can click 'yes' to and again it will get the mail. But after 30 seconds it does the same thing. I've got two other accounts set up fine, one a horde account (hosted webmail using POP3) and the other a iCloud .me account running on IMAP. What might be causing this and how I can remedy it? A bit more background: the machine is a MacBook Pro running Mac OS X v10.7 (Lion). Update 2013-11-02 I've updated Outlook to SP3, but I still get the same error.

• Issues regarding internet connectivity

  - by andySF

  Hello. My problem started when Yahoo Messenger stopped connecting. I've tried to see if Internet Explorer was working but will not load any page. The diagnostics of Internet Explorer says that is something wrong with my dns(using just ip of google or yahoo or my local webserver was not working). I use Windows 7 and at the moment i've had Internet Explorer 8 and after a lot of failing updates to ie9 I've successfully install the Romanian version of IE9(now i have ie8 after a system restore). Then I installed the service pack 1. I've done a lot of things and I will try to enumerate them, but my problem persists. Settings from Yahoo Messenger and Internet Explorer are OK. I've try to reset winsock and ip from netsh. I've scanned my pc with spybot, mallwarebytes, Trojan Remover(simplysup), Loaris Trojan Remover, Avast, Nod32, Kaspersky, Bitdefender,alot of registry cleaner including CCleaner and maybe others that I cannot remember now. I reset the registry permissions using subinacl. At a moment my files permissions was set jut to "trusted installer" and I've put the permission back to files and folders using the model of other windows 7 machine. I have try so many things that now i'm stuck in a loop using different security tools to check for problems. Oh, and my virtual machines are working just fine.(I'm using VirtualBox) Please Help. PS, Reinstalling Windows is not an option. Thank you!
