• MS Access 2003 - Format a Number with Commas AND Auto-Decimal

  - by Emtucifor

  On a report I have a control which is bound to a column which can have up to 3 decimal places. I want the number to format with commas separating thousands and millions, but I also want the number of decimal places to be automatic, so that if there is no decimal portion then no decimal at all is shown. 1234.567 -> 1,234.567 1234.560 -> 1,234.56 1234.500 -> 1,234.5 1234.000 -> 1,234 General format will give me the auto decimal places but no commas. Standard format gives the comma but is fixed to 2 decimal places. Doing my own =Format(Number, "#,##0.#") leaves the decimal point in and doesn't align properly, with extra space on the right of the number. Do I have to write my own VB function to give the format I want? It seems silly that Access (apparently) can't do this out of the box. This also seems really horrible: =Replace(Replace(Replace(Replace(Replace( _ Format(Number, "#,##0.000") & "x", "0x", ""), "0x", ""), "0x, ""), ".x", ""), "x", "")

• Hardware reserved memory issue

  - by Robert Koritnik

  I've seen lots of folks having problem with hardware reserved memory issue in Windows 7/Server 2008 R2. I have it myself but not as huge as others have. Problem description When you install Windows 7 (or its bigger brother Windows Server 2008 R2) your memory may not be fully utilised. If you look at Task Manager > Performance Tab > Resource Monitor > Memory Tab And scroll to the bottom of the list you will see a graphical representation of your memory. Some of it may be hardware reserved. Previous Windows versions didn't have this problem. System was able to utilise all memory available. Question Is there any solution to lower/remove hardware reserved memory? Sidenote I tried installing 32 and 64 bit versions but to no avail. I also tried both Windows: 7 and Server 2008 R2. But always get the same amount reserved by HW. On previous Windows versions I had more memory available because I'm simultaneously running 2 VMs on host (so three machines all together). And my memory peaks much higher now as it did on older versions.

• Modify registry for Internet Connection Sharing?

  - by Tim

  My OS is Windows XP. Quoted from How to Change the IP Range for the Internet Connection Sharing DHCP service Use Registry Editor to modify the data value of the IntranetInfo value in the following registry key: Hkey_Local_Machine\System\CurrentControlSet\Services\ICSharing\Settings\General The first number listed is the IP address of the internal IP address of the Connection Sharing host. The second number is the subnet IP address separated by a comma. Enter the first IP address of the new range followed by the subnet mask, separated by a comma. (For example, 169.254.0.1,255.255.0.0.). Modify the data value of the Start value in the following registry key: Hkey_Local_Machine\System\CurrentControlSet\Services\ICSharing\Addressing\Settings Change the value to the second address of the selected IP range. This address cannot be the same or a lower value than the IP address used for the IntranetInfo key. Modify the data value for the Stop value in the same registry key. Enter the last the IP address of the selected IP range. My registry table does not have Hkey_Local_Machine\System\CurrentControlSet\Services\ICSharing, and I don't know how to do with my registry table following the above three steps. Can someone guide me through it step by step?

• Is there a setting in Exchange Server 2007 that we can set to make these headers propogate and be received by a POP/IMAP client?

  - by Ruruboy

  When using EWS Managed API to send Email via Exchange Server 2007. I noticed that MAPI clients like MS Outlook display all custom headers. But when I use POP3/IMAP clients like MS Outlook Express. I have noticed that these custom headers do not display in the message opened from MS Outlook Express. Is there a setting in Exchange Server 2007 that we can set to make these custom headers propagate and be received by a POP/IMAP client? Also why do custom headers in example below display up in lower case in MAPI clients like MS Outlook? But surprisingly if we use SMTPClient class to send email then these headers display as sent with Case Sensitive letters. eg. Header. Example of Headers received by a MAPI client like MS Outlook via Exchange Server 2007 Received: from EXMAILVS1.blabla.com ([192.168.191.136]) by cashtp02.blabla.com ([XXX.XXX.XX.XXX]) with mapi; Mon, 20 Dec 2010 12:17:05 -0800 Content-Type: application/ms-tnef; name="winmail.dat" Content-Transfer-Encoding: binary From: asfsdf <[email protected]> To: asdsdf <[email protected]> Date: Mon, 20 Dec 2010 12:17:04 -0800 Subject: Please send me this header Thread-Topic: Please send me this header Thread-Index: AQHLoILek7g5cFgHQU6lHHfiKkdUMg== Message-ID: <[email protected]> Accept-Language: en-US Content-Language: en-US X-MS-Has-Attach: X-MS-Exchange-Organization-SCL: -1 X-MS-TNEF-Correlator: <[email protected]> customheader1: hello ali customheader2: hello Jace MIME-Version: 1.0

• Outlook 2007 OST File Indexing and OneNote 2007 Indexing are Broken

  - by Matt

  I'm running Outlook 2007 under Windows 7 Home Premium RTM. My OST file was previously being properly indexed but eventually searches significantly slowed down so I suspected a problem. Searching and indexing appears broken in OneNote 2007 as well as search time is now significantly longer. I brought up the Outlook 2007 Search Options dialog and noticed that my mailbox (running from an Exchange 2007 server) wasn't listed in the "Index messages in these data files:" list box. Next I ran the Windows "Find and fix problem with windows search" wizard which reported no errors. Then I brought up the Windows Indexing Options dialog which shows Outlook listed (as shown here): then clicked Advanced and Rebuilt the index. No dice - the listbox in the Outlook 2007 dialog still didn't show my mailbox. When I clicked the Modify button in the Indexing Options dialog I see the following: When I hover over the "oneindex://..." entry, the alt text indicates "This location is currently unavailable". When I delete it and rebuild the index, this entry returns. UPDATE: Comparison of the last screenshot above with a working PC shows that on the broken PC, the lower half of the dialog lists Outlook but neither Outlook or OneNote are showing in the upper half. The working PC has Outlook and OneNote in both parts of the dialog.

• EC2 Ubuntu - Force instance to use internal IP

  - by Peter

  I've just set up a micro instance on EC2 (AMI ID ami-e59ca991). I had hoped to avoid charges for a year as my usage falls well within the bound of the free tier. I have been charged $0.01 for "regional data transfer". I read here that this is because my instance is talking to its self via it's external IP address. From what I've Googled it looks like you can stop the charges by making sure that the instance uses its internal IP address. However, when I ping the hostname of my instance internally (via an ssh session) it resolves to the instances internal IP address. How can I configure my instance so that I do not get these charges? Is it as simple as adding a line to my hosts file? Additionally, is this the real reason for the charge? I'm concerned that I've misunderstood the pricing somewhere. I have Apace and MySQL (with phpmyadmin) running on the machine - could I be being charged for data transfer associated with these (I have only one flat HTML page and I have only logged in via phpmyadmin - I have no data in my database). Edit: Additionally, my user account on MySQL was declared as: grant all privileges on *.* to 'peter'@'localhost'; Should I have instead used the internal hostname for the instance? grant all privileges on *.* to '[email protected]'; Cheers, Pete

• Site to Site VPN with Fault Tolerence

  - by Nordberg

  Hello, I have a situation where I require an IPSEC tunnel between two sites. Site 2 is a small branch office with basic (ADSL) connectivity and Site 1 is the "main" office with SDSL and ADSL for redundancy should the SDSL fail. From Site 1, all traffic bound for the 172.0.0.0 network will then be sent down another IPSEC tunnel to a supplier's Remote Server. See this page for the basic premise (this is a rough idea and things can be moved about etc...) I am considering specifying Cisco ASA devices as the firewalls for both sites for all connections. Would it be possible to employ something like HSRC to provide a backup at Site 1 should the SDSL go down? I suppose the key aims here are that Site 2 can somehow failover to initiate a VPN to the ASA behind the ADSL at Site 1. I will have a 21 subnet mask on all internet connections so can play with Class C routing if need be... If I'm barking up the wrong tree with HSRC, is there another way I can acheive this without massive expenditure on Barracuda routers et al? Many Thanks.

• MySQL remote access not working - Port Close?

  - by dave.zap

  I am not able to get a remote connection established to MySQL.

• JBossMQ - Clustered Queues/NameNotFoundException: QueueConnectionFactory error

  - by mfarver

  I am trying to get an application working on a JBoss Cluster. It uses Queues internally, and the developer claims that it should work correctly in a clustered environment. I have jbossmq setup as a ha-singleton on the cluster. The application works correctly on whichever node currently is running the queue, but fails on the other nodes with a: "javax.naming.NameNotFoundException: QueueConnectionFactory not bound" error. I can look at JNDIview from the jmx-console and see that indeed the QueueConnectionFactory class only appears on the primary node in the Global context. Is there a way to see the Cluster's JNDI listing instead of each server? The steps I took from a default Jboss 4.2.3.GA installation were to use the "all" configuration. Then removed /server/all/deploy/hsqldb-ds.xml and /deploy-hasingleton/jms/hsqldb-jdbc2-service.xml, copying the example/jms/mysq-jdbc2-service.xml file into its place (editing that file to use DefaultDS instead of MySqlDS). Finally I created a mysql-ds.xml file in the deploy directory pointing "DefaultDS" at an empty database. I created a -services.xml file in the deploy directory with the queue definition. like the one below: <server> <mbean code="org.jboss.mq.server.jmx.Queue" name="jboss.mq.destination:service=Queue,name=myfirstqueue"> <depends optional-attribute-name="DestinationManager"> jboss.mq:service=DestinationManager </depends> </mbean> </server> All of the other cluster features of working, the servers list each other in the view, and sessions are replicating back and forth. The JBoss documentation is somewhat light in this area, is there another setting I might have missed? Or is this likely to be a code issue (is there different code to do a JNDI lookup in a clusted environment?) Thanks

• Using dnsmasq for accessing multiple nameservers assigned by DHCP

  - by Ash

  At my work desktop running openSUSE 11.4, I have a local network which gets its address, domain (work.site) and nameservers (10.100.1.1, 10.100.1.2) info through DHCP - which get written into /etc/resolv.conf I get to access the internet using the work network, and these 2 nameservers end up returning the entries for any public domain name lookups on the internet. I also have a private VPN that I end up connecting. The nameserver (10.111.1.1) and domain (private.site) are rarely bound to change for this network, but currently they're pushed by the openVPN client into networkmanager, and which also gets merged with the existing /etc/resolv.conf My resolv.conf ultimately ends up looking like this: search private.site work.site nameserver 127.0.0.1 nameserver 10.111.1.1 nameserver 10.100.1.1 As you can see the 2nd nameserver from my work network was pushed out because of the max 3 entry limitations. It is fine still, but would be a problem if that nameserver goes down for maintenance or something. So I found out that dnsmasq could help me here, and hence I setup dnsmasq just as a local DNS resolver without any DHCP support. So right now this is my /etc/dnsmasq.conf: resolv-file=/etc/resolv.conf server=/private.site/10.111.1.1 server=/1.111.10.in-addr.arpa/10.111.1.1 listen-address=127.0.0.1 bind-interfaces log-queries I've made dnsmasq get the list of nameservers from /etc/resolv.conf since NetworkManager seems to be updating this list correctly (for a max of 3 nameservers). I'm able to resolve the host names in both the networks correctly. So these are the questions I have: Is there a way I can make either NetworkManager or dhclient write out the list of nameservers somewhere else which I can make dnsmasq use as resolv-file ? How do I make dnsmasq use certain nameservers as the default for all queries ? Right now I notice that lookups for public domains on the internet are usually sent to both the nameservers - the one on work.site as well as private.site. It would be good if I can limit this only to work.site.

• Force Windows Local Subnet Traffic through a Gateway

  - by Beerey

  Hi all, We are attempting to route all traffic from a certain machine to a gateway. This works ok for traffic destined for subnets outside of the machine's subnet. However, traffic to machines in the same subnet as the source machine goes through an On-Link gateway in Windows. This means that the default gateway is ignored, and traffic in a subnet (for example, 192.168.50.10 - 192.168.50.11) flows. Destination Netmask Gateway Interface Metric 192.168.50.0 255.255.255.0 On-link 192.168.50.214 276 This route can be deleted from Windows, but when the machine is rebooted it always comes back. Adding a persistant static route to the gateway with a lower metric doesn't work, since it will still try the On-Link gateway after the persistant route fails. Adding each machine in a VLAN isn't an option due to the setup we have Adding a startup script to delete the gateway isn't a great option either, since users will have full admin access to the machine and might disable the script. We cannot transperantly intercept all network traffic on the subnet using Gratuitous ARPs or transparent proxying, since there are other machines on the subnet which use a different gateway The only way we have gotten it to work is by adding a persistant route to the gateway for the subnet traffic, and deleting the On-link route on reboot. The question is then. Is there a way to permanently remove this On-link route If not, is there a way to otherwise force even local subnet traffic to go through a gateway?

• Developer's PC - worth getting more than 8GB RAM?

  - by Borek

  I'm building a developer PC and am wondering whether to get 8GB or 12GB. It's a Core-i7 860 system, i.e., 1156 motherboards with 4 slots for RAM sticks, dual channel, usually up 16GB (as opposed to 1366 sockets where 6 banks / triple-channel are used). 8GB would be cheaper to get especially because price per GB is lower with 4x2GB compared to 2x4GB. Also the availability is worse for 4GB DIMMs here where I live; those are the main practical advantages of 8GB. (Edit: I should have stressed the price difference more - in the eshop I'm buying from, the difference between 12GB and 8GB is so big that I could almost buy a whole new netbook for it.) However, I understand that more RAM can never do harm which is the point of this question - how much of a difference will 12GB make as opposed to 8GB? Honestly, I've always been on 3.2GB systems (4GB but 32bit system) and never felt much pain from having too little memory - of course there could be more but for instance compiler's performance was usually held back by slow I/O or not utilizing multiple cores on my CPU. Still, I'm not questioning that 8GB will be useful, however, I'm not sure about the additional 4GB difference between 8 and 12 gig. Anyone has experience with 8GB / 12GB systems? The software I usually run all the time: Visual Studio or Eclipse (both should be fine with ~2GB RAM, after that I feel their performance is I/O bound) Firefox (it can never have enough RAM can it? :) Office (~500MB RAM should be enough) ... and then some smaller apps like Skype, other browsers, some background services etc.

• getting "No LoginModules configured" for JAAS login under WebSphere security domain

  - by user1739040

  I have a JAX-RPC web service running on WebSphere V7. It requires a UserNameToken for security. I have a custom login module (MyLoginModule) which extracts the username and password, and that module is defined as a JAAS application login in the websphere admin console. Using IBM RAD 8.0, I have bound the token consumer to the login module using the JAAS config name of the module. This all works fine and happy on my development server. Now I realize, that for deployment to another server, I am required to move the JAAS login from global security to a security domain. When I do that, it breaks my web service. I get this SOAP Fault message: com.ibm.wsspi.wssecurity.SoapSecurityException: WSEC6520E: Construction of the login context failed. The exception is : javax.security.auth.login.LoginException: No LoginModules configured for MyLoginModule According to the IBM docs: The JAAS application logins, the JAAS system logins, and the JAAS J2C authentication data aliases can all be configured at the domain level. By default, all of the applications in the system have access to the JAAS logins configured at the global level. The security runtime first checks for the JAAS logins at the domain level. If it does not find them, it then checks for them in the global security configuration. Configure any of these JAAS logins at a domain only when you need to specify a login that is used exclusively by the applications in the security domain. So I am looking to make sure my application is in the domain, and I have tried everything I can think of. (I have assigned the domain to "all scopes", to the entire cell, etc.) No luck, I keep getting the same error response to my web service client. Any help or hints are appreciated.

• VMware databursts to vCenter

  - by Erwin Blonk

  [edit Nov.16th 2009: Thank you for the responses. I'm no longer on this project so the problem is out of my hands. Be sure I will return with other problems :-) ] I have a strange occurence of regular databursts over my WAN links from 2 sites to a site with vCenter. What happens is that a vCenter server is managing local ESX 3.5 servers and 2 from 2 sites across a WAN link. Each server sends an approximately 3MB worth of TLS data (less than 10% of the time it varies to higher or lower) every 15 minutes (with a margin of 2 minutes). So far, I've not been able to single out a process that causes it. I looked through all applications on each site. So far, it seems to originate from one server on each site. Although it may be coincidence and therefore not relevant, I found that one server, with very few exceptions, does a burst at 00:00 on the hour. The other 3 during the hour are a bit off the 15 minute mark but back at the top of the hour, you can sync your watch on it. The other server follows 5 minutes after that with no such precision. But, as said, it never differs more than 2 minutes. Servers are ESX 3.5, vCenter is 2.5.

• Don't let the mouse wake up displays from standby

  - by progo

  I like to put my displays to powersave/standby mode when I leave the computer for a while. It would be ok if it weren't for oversensitive mouse. Sometimes the driver reads in some movement that's not visible to the naked eye (the cursor, that is) and it breaks the power save. It would wait for another 10 minutes before going back to its standby. My workaround is the following script bound to C-S-q: xlock -startCmd 'xset dpms 2 2 2' -endCmd 'xset dpms 600 1200 1300' -mode blank -echokeys -timeelapsed +usefirst By using xset I set the values to 2 seconds each before going to standby. It's not nice, anyway. Sometimes there are cool fortunes that I want to read before typing in the password. I could keep the cursor moving but it's cludgy. (By the way, xlock's option mousemotion doesn't help -- it just hides the cursor but the displays fire up nevertheless.) So the question: is there a way to make displays go standby and stay there until a keyboard key is pressed? I'm running gentoo and recent Xorg, but I hope the answer doesn't have to be distro-specific. Basically the answer can be as simple as how to enable/disable mouse within command line? It think that would do the job if DPMS doesn't know the idea.

• CPU and Motherboard clock speeds

  - by NZHammer

  I have been doing some reading about CPU clock speeds and how CPU clock speeds are calculated. After reading several articles, I have come to the understanding that your CPU clock speed is determined by: CPU clock speed = cpu multiplier x mobo clock speed A few questions came about after reading this which I cannot seem to find the answer to anywhere: If the CPU clock speed is dependent upon the mobo clock speed, then how is the clock speed of the CPU predetermined upon buying the CPU (i.e. written on the box without knowing what mobo is being used)? After installation, does the CPU adjust it's multiplier based upon the mobo clock speed to achieve advertised speeds? For example, if the CPU clocks speed is advertised at 2.4GHz and the mobo clock speed is 100MHz, will the multiplier be automatically set to 24x? Why does mobo clock speed seem to not be very important / talked about? For example, when I search on Newegg, mobo clock speed never seems to be listed. When I search enthusiast forums and overclocking forums, mobo clock speed is rarely mentioned. To me, it seems like the mobo clock speed would be pretty important. If I am understanding things correctly, a lower mobo clock speed means that you CPU must work harder to achieve advertised clock speeds. I guess that I should stop there with the questions for now, as I may be asking my questions based on incorrect assumptions. Thanks!

• Run script before shutdown/restart

  - by dtbarne

  I'd like to run a PHP script when an instance is told to shutdown, but of course before it actually finishes shutting down. My particular script is just looking to push some log files from the local partition to a another server. I've got the gist of how this process works, but I need some clarification. How I understand it. Please correct me if I'm wrong. Create an executable script in /etc/init.d (lets call it /etc/init.d/push-logs) Create a symlink to /etc/init.d/push-logs from /etc/rc0.d (shutdown) and /etc/rc6.d (reboot). The name should be KXXpush-logs Here's my questions: Of course - am I understanding correctly? For #2 above - it sounds like the lower the XX the better - is there too low a number I can use? Does it matter if it shares a number with another script? Does the script in /etc/init.d/push-logs HAVE to follow the standard init.d template (supporting start/stop, etc. commands)? This doesn't really apply to my use case. If possible I just want the script to be the following: #!/bin/sh # # Run PHP file prior to shutdown # /usr/bin/php /path/to/php_file.php

• Limit Apache 2 Memory Usage

  - by UltraNurd

  I am running a hobby webserver off of an ancient Blue & White G3/300 running Debian PPC Squeeze 2.6.30. The performance is okay for a while after a restart, but it eventually gets more and more bogged down. Right now it's at 76 days uptime, and the main culprit seems to be the memory usage of 10+ apache2 processes. I think I need to lower the values for StartServers, MinSpareServers, and/or MaxSpareServers, but I'm not sure which one to adjust, and there are three sections for each depending on which mpm module is in use. How do I tell which of the following sections I need to change, and what are some reasonable values given that the box has 448 MB physical memory (weird upgrade history of one each 64, 128, and 256 sticks)? <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 150 MaxRequestsPerChild 0 </IfModule> <IfModule mpm_worker_module> StartServers 2 MinSpareThreads 25 MaxSpareThreads 75 ThreadLimit 64 ThreadsPerChild 25 MaxClients 150 MaxRequestsPerChild 0 </IfModule> <IfModule mpm_event_module> StartServers 2 MaxClients 150 MinSpareThreads 25 MaxSpareThreads 75 ThreadLimit 64 ThreadsPerChild 25 MaxRequestsPerChild 0 </IfModule> There aren't any other instances of StartServers in my apache2.conf, but none of those mpm modules appear in mods-available or mods-enabled. Ideas? Thanks!

• Running multiple services on different servers with IPv6 and a FQDN

  - by Mark Henderson

  One of the things NAT has permitted us to do in the past decade is split physical services onto different servers whilst hiding behind a single interface. For example, I have example.com behind a NAT on 192.0.2.10. I port-forward :80 and :443 to my web server. I'm also port forward :25 to my mail server, and :3389 to a terminal server and :8080 to the web interface of my computer that downloads torrents, and the story goes on. So I have 5 port forwardings going to 4 different computers on example.com. Then, I go and get me some neat IPv6. I assign example.com an IPv6 address of 2001:db8:88:200::10. That's great for my websites, but I want to go to example.com:8080 to get to my torrents, or example:3389 to log on to my terminal server. How can I do this with IPv6, as there is no NAT. Sure, I could create a bunch of new DNS entries for each new service, but then I have to update all my clients who are used to just typing example.com to get to either the website or the terminal server. My users are dumber than two bricks so they won't remember to connect to rdp.example.com. What options do I have for keeping NAT-style functionality with IPv6? In case you haven't figured it out, the above scenario is not a real scenario for me, or perhaps anyone yet, but it's bound to happen eventually. You know, with devops and all.

• Display stretches 4:3 ratios; Adds scrolling to other ratios

  - by Matt

  I have a dual monitor setup. Normally, they both display at 1680x1050. They have been setup this way for about a year. I'm using Windows XP Professional 2003 x64 SP2. Today, out of nowhere, one of the monitors kicked back to a lower resolution. I was not playing with any configuration at the time.. in fact all I had done was close a window (maybe a browser). But the thing is that the resolution is still preserved partially by the fact that the screen will scroll when you move the mouse. So it's like looking through a 1024x768 window into a 1680x1050 world. The monitor itself does not appear to be damaged, because I also have it connected to my netbook (via KVM) and higher resolutions work fine. I tried uninstalling/reinstalling the drivers to no avail. System restore doesn't help either. I'm unsure of the exact ATI card I'm using.. Device Manager lists it as "Radeon X300/X550/X1050". There is no Catalyst Control Center software installed. I tried to install it, but there doesn't seem to be a way to install it by itself ... it forces you to install another driver, which breaks both of my displays, forcing me to go into safe mode and run system restore again. Any ideas? Thanks EDIT: After playing around more, I discovered that the "scrolling" behavior is only present for aspect ratios that are not 4:3. For 4:3 ratios, it just stretches out to fit the wide screen. My monitor's native ratio is 16:9 .. what could be causing it to think it needs to scroll?

• System Idle Process network traffic?-Updated

  - by Moab

  I was using NetBalancer and noticed network traffic on an unidentified service, but when I highlight it and then go to the lower center pane and click the parent process it says it is the System Idle process, it is showing incoming and outgoing traffic in the upper pane, anyone know why this Windows System Idle Process is talking on the network? Windows 7 HP 64bit . . . Edit, after blocking the traffic for that unidentified Service I checked my event viewer (Windows LogsSystem) and found 3 new events that were never recorded before and matched the time I blocked the traffic. So is this part of the Windows local DNS cache? Event ID 1014 DNS Client Events Name resolution for the name dns.msftncsi.com timed out after none of the configured DNS servers responded. dns.msftncsi.com Name resolution for the name wpad.home timed out after none of the configured DNS servers responded. wpad Name resolution for the name mscrl.microsoft.com timed out after none of the configured DNS servers responded. mscrl.microsoft.com . Then My Web Browser refused to work, I re-enabled the traffic and all returned to normal. .

• Socket options for a tcp server with 3G clients & frequent disconnections

  - by Joel

  I have a TCP server, written in java, sending and receiving many short messages, from 500 bytes to 100 KB long. It's a chess game and chat server, to make it simple. The server is running Debian 6. Half of the clients are connecting from 3G networks, and half over standard DSL. A portion of the 3G clients lose connection pretty often. The error I get on the server and on the client socket is Connection reset. I have come across this page at Oracle documentation: socketOpt. I am wondering what I could tune there to lower the number of disconnections from 3G clients. I don't mind about the ping or transfer rate, but just about the TCP disconnections. I am not skilled enough to understand the impact of each setting, but I sort of understood that the TCP window was important, although I don't know exactly how. So I'm asking if anyone here has an idea ? Thanks if you can help.

• Long Gigabit Ethernet Run

  - by Timothy R. Butler

  I am trying to get an Gig-E network between two buildings that are approximately 260 ft. away. While some TRENDnet switches failed to be able to connect to each other over Cat 6 at that distance, two Netgear 5-port Gig-E switches do so just fine. However, it still fails after I put in place APC PNET1GB ethernet surge protectors at each end before the line connects to the respective switches. So I find myself wondering if I simply need to find a better surge protector that doesn't degrade the signal as much (if so, what kind would you recommend?) or if I should give up on copper and use fiber between the buildings. If I opt to go the latter route, I could really use some pointers. It looks like LC connectors are the most common, but I keep running into some others as well. A media converter on each end seems like the simplest solution, but perhaps a Gig-E switch with an SFP port would make more sense? Given a very limited budget, sticking with my existing copper seems best, but if it is bound to be a headache, a 100 meter fiber cable is something I think I can swing cost wise.
