• Weirdly high ping on direct ethernet connection?

  - by Antriel

  I bought new Lenovo IdeaCentre H430 pc and I'm having problem with high pings. Windows 7 with on-board realtek NIC. Fresh install, fully updated, drivers installed from included CD. When I start pinging router (direct 1Gb ethernet connection, 1 hop), pings start at <1ms (which is fine) and after a while they jump to 300-1000ms. I loaded up live ubuntu to test if the problem might be in HW. It's not, in ubuntu pings were always <1ms. I also noticed that when I start using connection somehow, pings go down to 1ms, but go back up when I stop using it (tested by accessing live camera feed on LAN). Power Options set to max performance. I disabled Interrupt Moderation on the NIC, didn't help. I tested it in the safe mode with networking, same problem there. It slows down our client-server based programs and I have no idea what's causing it. All I could google up was that disabling Interrupt Moderation would help, it didn't though. Anyone had similar problems? tl;nr: Computer is giving high pings to router when idle and normal pings when network is under load, it slows down our software significantly.

• Transfering Files to server IP and port

  - by Mason

  I need to transfer files from my local computer on windows 7 to a server running linux. I access the server with putty through ssh at a specific IPv4 address and port number. I've attempted using the pscp command from my local computer but was denied access by the server. "Fatal: Network error: Connection refused" c:>pscp test.csv userid@**IPv4_Addres***:Port# /path/destination_file_name. Either the server blocks all pscp attempts from unauthorized users (most likely my laptop included) or I used the command incorrectly. If you have experience using this command, where exactly will the file get transfered to, I'm assuming that the path destination starts at my home directory in the server. Also if you have any other alternative methods of transfering the files let me know. Update 1 I have also tried using WinSCP however I got permission denied for that as well, it looks like the server will not let me upload or save files. Solved I had a complete lapse of memory and forgot about sudo (spent too much time with scripts the last 2 months), so I was able to change the permissions to allow external editing. Thanks for all the help guys!

• EventID 1058 Code 5, Sysvol is subdir of Sysvol - how to fix?

  - by nulliusinverba

  I have been trying to resolve this error, like many others: The processing of Group Policy failed. Windows attempted to read the file \domain.local\SysVol\domain.local\Policies{3EF90CE1-6908-44EC-A750-F0BA70548600}\gpt.ini from a domain controller and was not successful. Group Policy settings may not be applied until this event is resolved. This issue may be transient and could be caused by one or more of the following: a) Name Resolution/Network Connectivity to the current domain controller. b) File Replication Service Latency (a file created on another domain controller has not replicated to the current domain controller). c) The Distributed File System (DFS) client has been disabled. Error code: 5 = Access Denied. The incredibly helpful post is this one (http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/2003_Server/A_1073-Diagnosing-and-repairing-Events-1030-and-1058.html). Quoting from this post: HERE IS A LIST OF POTENTIAL PROBLEMS THAT CAN LEAD TO 1030 AND 1058 EVENT ERRORS: --Sometimes the permissions of the file folders that contain Group policies (the Sysvol folder) can be corrupted. --Sometimes you have problems with NetBIOS: --Sometimes the GPO itself is corrupt, or you have a partial set of data for that GPO. --Sometimes you may have problems with File Replication Services, which almost always indicates a problem with DNS --Sysvol may be a subfolder of itself: Sysvol/Sysvol I have the problem listed where sysvol is a subfolder of sysvol. The directory structure is: -sysvol -domain -staging -staging areas -sysvol (shared as "\\server\sysvol") -domain.local -ClientAgent -Policies -scripts Interestingly, the second sysvol folder is the one that is shared as "\server\sysvol". This makes me confident this is the issue with the permissions and error code 5. Also interestingly, my server 2008 R2 servers can see it fine - my server 2008 servers cannot, and get the error. This is consistent across all my servers. This latter fact makes me uncertain what I need to do to fix this up. Do I, e.g., simply move the shared sysvol folder up a level to replace the non-shared one? Any help greatly appreciated. Cheers, Tim.

• How to get rid of "Maxback Engine" for good?

  - by Jonik

  I used to have a Maxtor Shared Storage II network drive; it broke down long ago already. (Later I tried to recover some data from it, and partially succeeded, but haven't yet fully documented it on that question.) Anyway, I just noticed there are still some lingering bits remaining of the (thourougly crappy) software that came with the Maxtor device: a background process called "MaxBack Engine". I googled around a bit and found something related but not very useful: http://www.straitmac.com/jforum/posts/list/600.page http://discussions.apple.com/thread.jspa?threadID=725692 Under /Applications I found "Maxtor EasyManage.app" which I used to use for controlling the drive, and showed it some "rm -rf". Before deleting, I noted that the bundle did contain "MaxBack Engine.app" under Content/Resources. But still, after reboot, the "MaxBack Engine" process is back. I did notice though that it only appears when logging in with my usual user account; with another account it wasn't launched. So, dear Mac gurus, what could I do about this pest? I guess I could fall back to some Unix hackery and write a cronjob that kills any process with that name, but obviously it'd be nicer to be able to clean up from my computer everything left behind by Maxtor's piece of software.

• Content not being compressed even though I'm using zlib in php.ini

• Trouble in Team Viewer VPN Connection

  - by Sumit Pal

  I have completed initial vpn connection setup. It has connected. I have tested with ping and it is ok. My problem is, when I want to start file transfer in VPN it asks for username & password. So what is the user name? I have tried giving Computer-Name/User-Name. I have found my Computer Name by going to Control Panel/System/ & clicking 'Computer Name' tab & username from user accounts or it is shown when I login in windows account (Please correct me if the above procedure is wrong). But what is the password? I have tried giving the account password but it always give 'The username or password is incorrect.' My Question: How to find the username & password? For Information: a) I have Team Viewer 7 installed in one Windows XP PC & one Windows 8 PC. I like to create a secure connection between these two PCs. b) The two PCs are connected in the same local network via a router. Please ask if you need additional information.

• Slow browsing through IE on Windows Server 2012

  - by Volodymyr

  We've run into strange issue on the freshly installed servers. H/W: IBM server X3550 M4 7914; OS: Windows Server 2012 Std. Then we try to browse on the servers thru IE, not all sites are opened or it takes too long time to open the page, i.e. very few of them can be opened. Local FW are disabled. Servers are in a new subnet and traffic is allowed for it. VLAN is configured properly Another Windows Server 2012 host is running OK and Internet access works fine, but it is VM running on Hyper-V 2012. No proxy is used on the network. At the same time, if one tries to establish telnet session to any site on 80/443 ports - it does work. Google works as well. I've tried to configure single Qlogic adapter to check if the issue remains - it does. Teaming is configured with the means of QLogic, not by built-in functionality. IE Enhanced Security is disabled. IE settings were reset, more than once. Why would certain sites work while others not - Idk. I also tried to disable ecncapability and restart server - no luck netsh int tcp set global ecncapability=disabled Any thoughts? UPD1 VMQ is disabled. Servers are not running Hyper-V. UPD2 Servers were rebuilt from scratch, got a mail a few mins ago. Issue still remains. Teaming is now configured with the means of Windows Server 2012.

• Office365 Exchange: Cannot open shared two calendars in Outlook

  - by Mark Williams

  The problem: Outlook won't open the calendars on another user's mailbox and and a room mailbox, even when users have permission. Note: This problem is affecting more than one account on more than one machine. So I have a room mailbox and a personal mailbox on Exchange, both with shared calendars. There is a security group called "Scheduling Users" that have editor rights on both of these calenders. The room mailbox was created using PowerShell, per the instructions posted online (http://help.outlook.com/140/ee441202.aspx). Sharing worked on both of these folders initially. Users can still access these folders using OWA. So on to the problem. When users try to open these calendars in Outlook they receive one of the following messages. The set of folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance. Cannot open this item. Cannot open the free/busy information. The attempt to log on to Microsoft Exchange has failed. What I have tried so far: Resetting the permissions on both of the mailboxes. I deleted the security group permissions on both mailboxes, applied the change, then waited a bit and gave the permissions back. Deleted the OST file of the shared calendar from the Outlook data directory That is all I have been able to find online. Any thoughts? I have been going back and forth with the Office365 support folks for a while and they seem stumped too.

• SQL cluster instance names for large project

  - by Sam

  We're setting up two clusters. One dev and one prod. The Production will host two SQL instances - a OLTP and a DW. The development will host 4 OLTP non-production environments and at least one DW non-production. We're working on getting more DW non-prods and possibly more OLTP systems. I'm considering a naming scheme like this, where PROJ would be 3 initials for the project name. Dev Cluster MSSQLPROJD1\D1 (DEV) MSSQLPROJD2\D2 (TEST) MSSQLPROJD3\D3 (QA) MSSQLPROJD4\D4 (STAGE) MSSQLPROJD5\D5 (DW) Prd Cluster MSSQLPROJP1\P1 (PRD) MSSQLPROJP2\P2 (DW) To the left of the slash, each name must be unique network wide. On each server, the instance name, to the right of the slash, must be unique. Any thoughts on this? I'm trying to avoid having instance names drifting from reality as the project progresses - say we change what we call a certain environment or want to repurpose one. Then we can update a listing of the purposes for the instances and be done with it. How has a scheme like this worked out for you? Maybe you do things another way in your shop - tell me about it. Thanks.

• virtual machines, dual booting and data disks on SSD

  - by stevemarvell

  This is in planning, so if I've got the strategy wrong, please let me know. There are multiple questions here, but I think they all degenerate to the same answers. The hardware is a laptop with a single SSD. I'm trying to not lose the performance of the SSD. I plan a native dual booting Windows (plus cygwin) and Linux machine which is my BYOD and represents the development environment. I keep the codebase on a shared partition (though sometimes this is an external thunderbolt SSD) which can be natively "mounted" by whichever OS is in operation. I boot into one or the other environments depending on the task in hand. Sometime I have to develop with windows tools, but generally, Linux is my preferred development environment. It would be ideal if I could VM the other OS and run either in either. I'm going to assume, because I've not found a sensible VM based solution, that I have get samba involved to share the code partition between VMs. Is this going to blow my SSD performance in the VM? The client also supplies me with a VM for the target environment, usually linux. This is not often suited to development and is used for testing only. I normally keep two copies of this, one as a sandbox and one which I deploy to using the client's preferred method. I keep these VM snapshots on the shared partition. The latter is interacted with over the network and so has no disk sharing requirements. However, it would be useful for the sandbox to be able to "mount" the code base from the natively running OS. Is this samba or nfs again, depending on the native OS? Am I missing a trick which allows this to all work smoothly with all four environments running at once without loosing the SSD performance?

• AFP/SSH stopped working on OS X Server

  - by churnd

  I have 3 Mac OS X servers all bound to AD, all configured in the Golden Triangle setup. All 3 are completely separate from each other in terms of services, but all reside on the same internal network and are all bound to the same Active Directory domain. Two are 10.5.x (latest updates) and one is 10.6.3. Last weekend, all 3 simultaneously stopped allowing Active Directory users access to certain services, specifically AFP & SSH. SMB still works fine on all 3. I asked the AD admin if anything changed, and he said "Yes, we made a change to user accounts to toughen up security", and suggested I use [email protected] instead of just username. This still didn't work. I have completely removed one of my servers from AD, and re-joined, but this didn't work either. I can do kinit from command line and get a Kerberos ticket. sudo klist -ke shows all services are configured to use the correct Kerberos principles. I have been scavenging the logs for any useful info. The AFP log just shows that I'm connecting and disconnecting. The DirectoryService.log shows stuff about misconfigured Kerberos hashes, but my research is showing that's not uncommon. /var/log/system.log isn't showing anything useful that I can see. I'm not sure where to go from here. Any help/ideas appreciated.

• Access node.js local server though mobile via same shared wifi

  - by laggingreflex

  EDIT: I was stuck in this situation before but then it was Apache-related But this time I'm using NodeJS, so the old answer doesn't help. I'm running apache a NodeJS webserver (on port 80) on Windows 7. I want to access the webserver through my mobile which shares the wifi router with my pc locally. http://localhost works from PC. But I can't access http://192.168.1.4 from either my phone or even my computer. ipconfig /all on my computer lists my ip address as 192.168.1.4 Wireless LAN adapter Wireless Network Connection: IPv4 Address. . . . . . . . . . . : 192.168.1.4(Preferred) I can ping my phone's (internal) ip address [192.168.1.5] from PC and vice-versa, I can ping my PC [192.168.1.4] from my phone. So why can't I access http://192.168.1.4 from my phone? (or PC) Firewall is off.

• Group Policy for DNS Server Addresses

  - by John

  This question deals strictly with the methodology of using Active Directory to publish DNS settings and controlling the DNS server address order to domain attached clients. This is not asking about if this is the right function, role, or best use of group policy; but rather, how to make it work. I would like to be able to publish in group policy DNS addresses and possibly control the order in which the client consumes the addresses. I have tried following the information from this site without success. I set the following setting within group policy, but the client never shows the settings within the TCP/IP properties. Computer Configuration/Administrative Templates/Network/DNS Client/DNS Servers I did list them as a single space separated list. For example, the following: 192.168.0.1 192.168.10.3 192.168.34.2 192.168.2.67 192.168.56.99 192.168.99.23 This would be for Windows 7, Windows Server 2003, and Windows Server 2008 clients. I am not sure what I am doing wrong or how to get this to work. Am I missing a setting? Do I need to set something differently?

• Vlaning on WNR3500L

  - by ageis23

  When I try connecting to my wireless network it attempts to connect then gives up. There's something strange going on with the mac's. The eternet switch and all the vlan interfaces have a mac 00:FF:FF:FF:FF:FF. config 'switch' 'eth0' option 'vlan0' '2 3 4 8*' option 'vlan1' '0 8' option 'vlan2' '1 8' config 'interface' 'loopback' option 'ifname' 'lo' option 'proto' 'static' option 'ipaddr' '127.0.0.1' option 'netmask' '255.0.0.0' config 'interface' 'lan' option 'type' 'bridge' option 'ifname' 'eth0.1' option 'proto' 'static' option 'netmask' '255.255.255.0' option 'ipaddr' '192.168.2.1' option 'ip6addr' '' option 'gateway' '192.168.1.253' option 'ip6gw' '' option 'dns' '' config 'interface' 'wan' option 'ifname' 'eth0' option 'proto' 'dhcp' option 'ipaddr' '192.168.1.8' option 'ip6addr' '' option 'netmask' '255.255.255.0' option 'gateway' '192.168.1.253' option 'ip6gw' '' option 'dns' '192.168.1.253' config 'interface' 'dmz' option 'ifname' 'eth0.2' option 'proto' 'static' option 'ipaddr' '192.168.0.1' option 'netmask' '255.255.255.0' Any help on this will be greatly appreciated! When I try setting the mac using macaddr it does nothing. It works perfectly fine when I turn the authentication off. I've also discovered that when wpa2 is switched on I don't receive a association reply from ap. thats my hostapd.conf interface=eth1 driver=broadcom bridge=br-lan ssid=O2BB3 wpa=2 wpa_passphrase=prettywoman wpa_key_mgmt=WPA-PSK rsn_pairwise=CCMP Btw that password is only temporary while am testing.

• FWBuilder DNS Object Run Time - when exactly does it resolve the DNS name?

  - by Jakobud

  In Firewall Builder, when you use the DNS Object and set it to run time, when exactly does the firewall (iptables in our case) actually resolve the DNS name? Is it whenever a call is made to that DNS name in the firewall? So the firewall would resolve the name on the fly whenever someone/something tries to access that DNS name? Or is it when you execute the fw script to load the rules into iptables? So in this case, it would resolve the DNS name that one time and then hard-code the resulting ip address into the iptable rules? From what I read, I think its #1, but it's just not 100% clear to me. We have two servers for a certain function on our network. One is the primary server and one is backup. alpha0.domain.com alpha1.domain.com In DNS we have this: alpha.domain.com -> alpha0.domain.com If the primary server goes down and we need to switch to the backup, I just change our local DNS record to point to alpha1.domain.com instead. So back to the firewall, if I just put in a Domain Object as alpha.domain.com, do I have to reload the firewall rules every time we switch to the backup alpha server and change the DNS record? Or will the firewall automatically resolve to the correct address even after the switch?

• Setting up port forwarding for web server

  - by Javier Badia

  This could belong on Super User, but I thought this place was more appropiate. I want to run Apache in my computer and want to make it available to the outside world to test a couple things. Apparently, I have to go into my router's (a TP-LINK TD 8910G) settings and forward port 80 to my PC's IP. So far so good. Thing is, since the router uses a web based interface and it's kind of stupid, it told me that since I was using port 80 for this, I should access its settings through port 8080. Maybe it can't detect requests coming from the LAN, I don't know. Point is, now neither port can't access the configuration, and I can't access Internet. Specifically, trying to access anything (including 192.168.1.1, the router's settings) through port 80 turns up a blank page (maybe if I had the server running in my computer I'd get something, but I don't want to risk trying, I had to reset the router and restore the settings), and port 8080 gives a "Can't establish connection" error in Firefox (and similar ones in other browsers). Is there a way to configure the router to not redirect requests coming from inside the network? I'm a beginner with this stuff, so please try to explain in a simple way. If this is more appropiate in Super User, I'm sorry.

• Running HTTP and HTTPS connections for a single domain (say, www.example.com) through a Cisco ACE SS

  - by Paddu

  My web application config has a Cisco ACE load balancing across a server farm and I want to use the ACE as an SSL endpoint as well. To make this work, the network architect has come up with a design where all secure pages have to be served from secure.my-domain.com, while non-secure pages are served up from www.my-domain.com. The reason for this is apparently that the configuring the Cisco ACE to accept HTTPS requests on port 443 for a particular public IP prevents the simultaneous acceptance of HTTP requests on port 80 for the same IP. While I'm not a networking (or Cisco) expert, this seems to be intuitively wrong, as it would prevent any website using the Cisco ACE to serve pages on http://www.my-domain.com and https://www.my-domain.com simultaneously. In this situation, my questions are: Is this truly a limitation of the Cisco ACE when used as an SSL endpoint? If not, then can I assume that we can set up the ACE to accept connections for a particular IP on ports 80 and 443, and function as an SSL endpoint for the incoming requests on 443? Links to appropriate documentation most welcome here. Assuming the setup in the previous question, can I then redirect both sets of requests to the same server farm on the same port?

• How do I setup JBoss 5.1.0.GA to run multiple instances?

  - by djangofan

  Does anyone have any experience or advice in setting up multiple JBoss 5.1.x instances on the same machine that has 1 network card? Here is what I did: Installed JBoss 5.1.0.GA into c:\myjboss 1.5. I copied the server/default directory to server/ports-01 and server/ports-02 so they have their own config. did I assume correctly? Ran .\run.bat -c ports-01 Ran .\run.bat -c ports-02 At this point there are 2 instances but the second instance doesn't load correctly because of what is probably a few port conflicts. For example: the http port ends up being 8080 for both instances, which it gets from line #49 in the C:\myjboss\server\all\conf\bindingservice.beans\META-INF\bindings-jboss-beans.xml file. Earlier in the server load it clearly gets the value from line#63 in that same file. I don't know why it gets part of the port config from line #49 and the other part from line#63. Confused. I also tried: .\run.bat -Djboss.service.binding.set=ports-01 -c ports-01 and it made little difference. Any ideas on what I am doing wrong?

• What Media Extender / Centre Set up should I use?

  - by Bryn Hird

  I have installed cat6 throughout the house which I use for telephony and network. In my cellar I have a NAS Server, gigabit switch and I want to install a Media Centre to stream my video's, music, photo's and live TV (coax from the aerial to the cellar) over the cat6. Yeah I know I can get stuff on the internet but shared experience of watching TV as a family as it happens is a big plus for live TV. I'm aiming for 1080p. I want different users to be able to watch different channels. Max users = 4. I've played a little with Windows Media Centre, works fine with live TV. Likewise I have XBMC up and running with live TV. The issue I have is what do I put near the TV. I'd like a consistent user interface (grandma and the the other technophobes in the house are continually pestering me on how to use different TVs, change channel, inputs etc.) so a key part of this for me is to make the user experience the same and simple i.e. no keyboards / PCs hanging around the TV. I've just bought a Linksys DMA 2200 to test the Windows Media Centre, but obviously off eBay as they're a dying breed. And with Windows Media Centre removed from Microsoft plans such devices will get rarer. And as for 1080p, think I can forget it with that set up. I have tested XBOX 360, also works but ditto on Microsoft plans for WMC. I was thinking of a WD Live TV to test the XMBC setup. Now to the question. Any advice on Media Centre / Extender setups that will do the job as above and have some degree of futureproofing (building my own with my Raspberry PI is a last resort). I'd like to understand the standards involved in the futureproofing if anyone knows (DNLA, RVU etc.).

• Adding subnet to a vsphere with single vcenter and esxi host

  - by Ilya Rakhlin

  Let me start of by saying that I do not specialize in networking, I am in the process of adding additional VMs to a testing environment and wanted some recommendations. In this case I am running a single ESXI 5.1 host and a single Vcenter management server. The problem is, I need another range of IP addresses added to the existing setup; hopefully without reconfiguring everything. Currently the esxi host is configured to IP: 192.168.100.200, gateway: 192.168.100.1 and subnet: 255.255.255.0. All of the VMs are running some version of linux with hard coded IP addresses in that range, and using that subnet. The VMs I am about to deploy I want to be on the 192.168.101.X network. Is it possible to add an additional subnet to this existing system that will also communicate with the current subnet? The esxi host has 6 physical NICs but only one connected as it is only a testing system; not sure if that matters. Are there any other ways to accomplish this hopefully without restarting or at least reconfiguring the IP addresses for each VM? Reason: Due to the configuration of the VMs to run the applications that we need I am using a large amount of the current IPs in the potential range (mostly VIPs). I will be setting up a new version of this “environment” while keeping the old one, thus potentially running out of IP addresses.

• I want to use OpenVPN to access the web and email from China. How?

  - by gaoshan88

  My question: How do I use my already existing OpenVPN setup to enable secure, remote web surfing and email checking from open wireless hotspots? Some long winded details: I am running Ubuntu and have OpenVPN up and working fine as a server. My client machine connects fine as well. However, that just gets me a secure connection to my home network. What I want is to be able to access my VPN server and surf the web or check email securely from anywhere with an open wireless connection. I am frequently in China and having secure, unblocked access would be a boon (especially since I like to work from tea houses and coffee shops and I've already had a password sniffed and hacked once). I already know how to tunnel over SSH via a SOCKS proxy using something like: ssh -ND 8887 -p 22 [email protected] but since I have OpenVPN I figure why not try it? So... what are the steps involved in making it so I can connect to my VPN and the surf and check mail to my hearts content (slowly to be sure but at least it wold be secure). Thx!

• New SBS 2011 installation (not migration) in an existing 2008 R2 domain

  - by Tong Wang

  My current network setup has two servers: a Windows 2008 R2 with TMG 2010 as edge firewall (TMG server), a second 2008 R2 with DC, DNS and Hyper-V roles (DCDNS server). I was trying to install SBS 2011 as a child partition on DCDNS, first I installed SBS 2011 in English and did the migration successfully. However, later on, I found that I can't change the display language in SBS 2011 once it's installed (but the clients require a different language), so I had to re-install the SBS in a different language. It is during the re-installation that the problem came up: the migration can't be completed with some error message stating "can't access the source server". I re-ran the migration preparation tool, but it didn't make any difference. I wonder if it's because the source server can only be "migrated" once. Since I only need to setup a handful of users and computers, so I decided to do a new install of SBS and picked a different domain name. But I can't get the SBS to connect to LAN: it can't ping other servers, neither can other servers ping the SBS server. I've tried to stop the DC/DNS services on DCDNS and restart SBS, but with no difference. Anyone has idea how to fix this problem?

• Is there a faster way to change default apps associated with file types on OS X?

  - by Lri

  Is there anything more convenient than using RCDefaultApp or Magic Launch, or just repeatedly pressing the Change All buttons in Finder's information panels? I thought about writing a shell script that would modify the CFBundleDocumentTypes arrays in Info.plist files. But each app has multiple keys (sometimes an icon) that would need to be changed. lsregister can't be used to make specific modifications to the Launch Services database. $ `locate lsregister` -h lsregister: [OPTIONS] [ <path>... ] [ -apps <domain>[,domain]... ] [ -libs <domain>[,domain]... ] [ -all <domain>[,domain]... ] Paths are searched for applications to register with the Launch Service database. Valid domains are "system", "local", "network" and "user". Domains can also be specified using only the first letter. -kill Reset the Launch Services database before doing anything else -seed If database isn't seeded, scan default locations for applications and libraries to register -lint Print information about plist errors while registering bundles -convert Register apps found in older LS database files -lazy n Sleep for n seconds before registering/scanning -r Recursive directory scan, do not recurse into packages or invisible directories -R Recursive directory scan, descending into packages and invisible directories -f force-update registration even if mod date is unchanged -u unregister instead of register -v Display progress information -dump Display full database contents after registration -h Display this help

• How to limit SMTP delivery to hourly batches

  - by Jeremy W

  Moved over from StackOverflow. Sorry if you saw it there first In an effort to keep us from being labeled spammers by major ISPs (in addition to SPF records, privacy policies, CANSPAM compliance and the like) - I wanted to limit the amount of mail we send out an hour. Is this possible in W2K3 SMTP server? I was looking at outbound connection properties in the SMTP virtual server config screens...It's just not that clear if tinkering with those settings are going to do what I want. In a nutshell, I'd love mail being sent by this server to queue up and send for example, 5,000 messages every 10 minutes or so. Mail is being sent via ASP.Net. Also, I wouldn't be sending 1 million a day. Probably 30,000 tops - and doing that only a few times a month. I'm just trying to avoid a tidal wave of 30k going out in 1 minute and setting off every network spam monitoring alarm in North America. I know I could do it with a combination console app / scheduled job. My question was if there was an easier way to accomplish this with the Virtual SMTP Server settings on Win2k3 Is this possible?

• Connect to Apache times out randomly

  - by Amadan

  We are trying to set up an Apache server on a remote machine, but we experience strange behaviour. Checking with telnet remote.machine 80, one of these things happen randomly: Connect and serve content normally (no delay) Connect after a long pause Connect normally, then time out without response Timeout on connect Once connected, the request seems to be processed normally. These things do not occur if I connect from that machine directly to localhost 80. The Apache is dedicated, as is the server it runs on (runs only this one application, no-one else is using it for anything else). I am not an administrator of the remote site, and I do not know the network architecture over there, but apparently it's firewalled: (HTTP port is open, SSH port is IP-restricted, most others are closed). If there was any one pattern, I might have some ideas, but this variety of symptoms baffles me. Any ideas as to what could be causing this? Apache is 2.2; Server version is: Linux version 2.6.9-22.ELsmp ([email protected]) (gcc version 3.4.4 20050721 (Red Hat 3.4.4-2)) #1 SMP Mon Sep 19 18:32:14 EDT 2005
