• HAProxy and Intermediate SSL Certificate Issue

  - by Sam K

  We are currently experiencing an issue with verifying a Comodo SSL certificate on an Ubuntu AWS cluster. Browsers are displaying the site/content fine and showing all the relevant certificate information (at least, all the ones we've checked), but certain network proxies and the online SSL checkers are showing we have an incomplete chain. We have tried the following to try to resolve this: Upgraded haproxy to the latest 1.5.3 Created a concatenated ".pem" file containing all the certificate (site, intermediate, w/ and w/out root) Added an explicit "ca-file" attribute to the "bind" line in our haproxy.cfg file. The ".pem" file verifies OK using openssl. The various intermediate and root certificates are installed and showing in /etc/ssl/certs. But the checks still come back with an incomplete chain. Can anyone advise about anything else we can check or any other changes we can make to try to fix this? Many thanks in advance... UPDATE: The only relevant line from the haproxy.cfg (I believe), is this one: bind *:443 ssl crt /etc/ssl/domainaname.com.pem

• Deactivate SYN flooding mechanism

  - by mlaug

  I am running a server that is running a service on port 59380. There are more than 1000 machines out there connecting to that service. Once I need to restart the service all those machines are connecting at the same time. That made some trouble as I have seen that log entry in kern.log TCP: Possible SYN flooding on port 59380. *Sending cookies*. Check SNMP counters. So I changed sysctl net.ipv4.tcp_syncookies to 0 because the endpoints to not handle tcp syn cookies correctly. Finally I restarted my network to get the changes in production Next time I had to restart the service, the following message was logged TCP: Possible SYN flooding on port 59380. *Dropping request*. Check SNMP counters. How can I prevent the system for doing such actions? All necessary counter measures are done by iptables...

• Prevent folder deletes at top level only on Server 2008

  - by DomoDomo

  I'm trying to prevent folders moves, really folder delete in NTFS parlance, for series of folders within a network share. So let's say I have: FolderA, FolderB, FolderC. Each folder has various files and subfolders. I want the Domain Users group to have modify access to all files and folders beneath FolderA, FolderB, and FolderC. However I don't want them to be able to delete these three top level folders. The issue we are having right now is people keep accidentally dragging one top level folder into another. I've tried used advanced NTFS permissions to deny domain users delete access to these top level folders, and set the permissions to apply to "This folder only", however it seems to only affect sub-folders, and not the top level. Platform is Server 2008 Standard. Thanks in advance.

• Disable OS X Portable Home Directories for specific hosts for all users, not just individuals?

  - by Paul Nendick

  Would it be possible to block any and all Portable Home Directory services for specific hosts? Something like MCX's "MobileAccountNeverAsk-" but for the whole workstation? We have a network with both portable and stationary machines. I'd like our users to be able to use all machines, going portable on the MacBook but not being bothering with syncing when logged into stationary iMacs or Mac Pros. The Open Directory servers are running Snow Leopard (for now) and all clients are running Lion. Thanks! Paul

• anonymous access to ftpd

  - by gcb

  I need FTP on my local LAN so my scanner can send me scans. I am on Debian sid. I installed ftpd and created the user anonymous. I removed anonymous from /etc/ftpusers When I try to login as anonymous it says: login failed. I can't seem to find any log file. I'm using FTP server (Version 6.4/OpenBSD/Linux-ftpd-0.17) update:I needed that so my printer had one place to store my scanned documents on the LAN. solved that buying a dedicated USB pen drive (thankfully I bought a printer one with plenty of options) but in the past this was a very simple task. Install ftpd, specify the directory for anonymous access, and be done with it. now every ftp daemon has several layers of security and chroot in it's core... this is just crazy when all you need a place for a printer to dump files in a secured network.

• Outlook + Exchange 2007: it is possible to rid of local OST files?

  - by kdl

  I am looking for a solution which would allow to use a convenience of Outlook as a mail client app while at the same time have no PST or OST files on a local computer. Even in 'non-caching' mode Outlook creates an OST file where it downloads everything from the Exchange server. OWA does not create any local files (except cookies I believe) but lacks some of the nice features Outlook has. Would it be feasible to place OST files on a network share? Maybe the solution exists for some other client+server pair?

• WiFi can't connect after suspend

  - by CyberOPS

  I've had this problem since Ubuntu 11.10 (my first install) but I was able to get around this issue with this answer. After I installed Ubuntu 12.04.1 I tried to use the same fix as before but I couldn't get it to work. I've also tried a couple other different fixes I found around the web but they didn't work. Basically here's what happens: I can see all the networks in my area. When I try to connect to one of them it never connects, it keeps disconnecting. After a little bit it asks for the password again but its already filled in correctly. If I hit okay it will do the exact same thing again. So does anyone know how I can get this fixed? INFO: Computer: HP Pavilion dv6t-6b00 CTO Quad Edition Entertainment Notebook PC Network Card: Intel® Centrino® Wireless-N 1000 OS: Ubuntu 12.04.1 (x64) dual booting with Windows 7 (x64) (*Not using Wubi*) Wireless Card Driver: iwlwifi UPDATE: I was about to reinstall with the DVD I made with the ISO from the official source but discovered the same issue happens on the disc's Ubuntu preview feature. I still was unable to fix it as before. I also tried the Xubuntu demo, and the same. Re installing the driver hasn't worked either.

• DNS Help: Move domain, not mailserver

  - by Preserved

  I'm in the middle of launching a new website for an already-in-use domain. The domain has a complicated email system so we'd like to move that over to the new server a bit later on. Currently the domain DNS is managed by the current webhost. I plan on moving the DNS management back to Network Solutions, then point the A record to the new website's IP. However, currently the DNS has the MX record the same as the A record. When NetworkSolutions is managing the DNS, and I point the A record to the new IP, then the MX record can't be the A record.. Right now: A Record mydomain.com points to IP address 198.198.198.198 MX record mydomain.com points to IP address 198.198.198.198 What I want: A Record mydomain.com points to IP address of new server MX record somehow points to current existing mailserver Does this even make sense?

• How do I usb tether my Cyanogen modded G1's internet connection to my Toshiba Tecra 8000 running Xubuntu?

  - by atticus

  I have usb-tethering enabled in my phone. It works fine with Vista. When I plug my phone into my Tecra 8000 laptop running Xubuntu, dmesg shows: "usb 1-1: new full speed USB device using uhci_hcd and address 8". I see that the OS has detected it as a storage device, but I can't get it to function correctly as a network device. /dev/us* shows no usb0, but it does show /dev/usbdev1.1_ep00 /dev/usbdev1.1_ep81 /dev/usbdev1.8_ep00 ... usbdev1.8_ep83 I could just use the wireless tether app for android, but I can't get my Netgear wg511 v2 (made in China) wireless card to work in this laptop either. But that's another post for later.

• Esxi with iSCSI SAN slows down with many multiple VMs running

  - by varesa

  I have a server with ESXi 5 and iSCSI attached network storage(4x1Tb Raid-Z on freenas). Those two machines are connected to each other with Gigabit ethernet, and a procurve switch in between. After a while, if I have many(4-5 or more) vms running, they start to get un-responsive (long delays before anything happens). We are trying to find the reason behind this. Today we looked at esxtop, and found that DAVG of that iSCSI LUN stays at 70-80. I read that +30 is critical! What could be causing those high response-times?

• Windows 7: how can I add an IP range in the "route" command?

  - by KeyStroke

  Hi, I'm using two network connections, and I tried using the "route" command so that when I access a specific internal IP on my LAN, it would use connection 1, anything else would go normally through connection 2 (which doesn't have access to my LAN). The problem is I have a bunch of internal IP's that I need to access, and the "route" command doesn't seem to allow me to add an IP range instead of specific IP. And connection 1 doesn't have internet access, so I can't use it as my default connection. Any idea how this can be solved? Your help is appreciated

• Streaming audio to headless linux box

  - by Ralph

  I have a dual boot (Win 7 + Ubuntu) PC connected via wifi with my music collection on a local HDD. I usually use Rhythmbox on Ubuntu or Winamp on Windows to listen to my music but I'll change if I have to. I also have a Raspberry Pi (low power PC running Debian) in the living room that is usually headless and connected via ethernet. The Raspberry Pi is also connected to my living room speakers via an amp. I would like to be able to stream music from my PC over the network to the linux raspberry pi. What software can I use to do this? Some sort of audio client\server?

• CentOS: OpsCenter does not see other node's agent

  - by Alice

  I'm new with Apache Cassandra. I am trying to install a little sample cluster using two CentOS server. I followed the documentation (Tarball installation) and the nodes are up. However, when I go to OpsCenter, the nodes cannot see each other's agent (there is always "1 of 2 agents connected"..I tried to fix, but nothing change). I tried both to disable and enable SSL, I tried to set the incoming_interface in opscenter.conf, I tried almost everything the network suggested to me, but the problem persisted. Now, I have SSL enabled, and agent log tell me: "There was an error when attempting to load stored rollups." Is there someone that could help me, please?

• Can ping/nmap server, nothing else

  - by lowgain

  I was SSHed into our ubuntu LAMP server , and was just doing a svn update, which hung. I disconnected, and since then, I have not been able to SSH in or view any of our websites (neither from my network or through a remote machine). I would have just assumed the server went down, but I can ping the machine and get really quick responses. Using nmap on the box shows all the normal ports open, so I am confused This server is hosted remotely in a datacenter, do I have any remaining options except contacting them for support? Thanks!

• Exchange 2010 user not receiving mail from another user

  - by eth0

  I have an Outlook 2010 user who can't receive email from another Outlook 2010 user. They are both in the same mailbox server in the same network. They can both send and receive email to anyone else in the organization. One just can't receive from the other. It's very strange. Exchange server was recently migrated from 2007 to 2010 but one of the users described is a new hire which was created on the 2010 server. I have other new hires created on the 2010 server that work fine. I tried having the user send from OWA and it still doesn't get through. What else can I do to troubleshoot this issue? Thank you.

• USB Device With Embedded Fileserver

  - by Richard Martinez

  I'm attempting to access logs from a proprietary hardware box with no reasonable hope of modifying the software. There is a process on the device to dump log files to a flash drive on the USB port after entering a code sequence. Currently, analysis of the logs requires the following: Physical presence at the device Manual entry of the code sequence Removal of USB device Insertion of USB device into a normal Linux box I'm hoping there is some sort of device that can act as a USB mass storage device but simultaneously make it's contents available as a network file share (wired preferred). Does such a device currently exist? A combo hardware/software solution would also work.

• Business Forces: SOA Adoption

  The only constant in today’s business environment is change. Businesses that continuously foresee change and adapt quickly will gain market share and increased growth. In our ever growing global business environment change is driven by data in regards to collecting, maintaining, verifying and distributing data.  Companies today are made and broken over data. Would anyone still use Google if they did not have one of the most accurate search indexes on the internet? No, because their value is in their data and the quality of their data. Due to the increasing focus on data, companies have been adopting new methodologies for gaining more control over their data while attempting to reduce the costs of maintaining it. In addition, companies are also trying to reduce the time it takes to analyze data in regards to various market forces to foresee changes prior to them actually occurring.   Benefits of Adopting SOA Services can be maintained separately from other services and applications so that a change in one service will only affect itself and client services or applications. The advent of services allows for system functionality to be distributed across a network or multiple networks. The costs associated with maintain business functionality is much higher in standard application development over SOA due to the fact that one Services can be maintained and shared to other applications instead of multiple instances of business functionality being duplicated via hard coding in to several applications. When multiple applications use a single service for a specific business function then the all of the data being processed will be consistent in terms of quality and accuracy through the applications. Disadvantages of Adopting SOA Increased initial costs and timelines are associated with SOA due to the fact that services need to be created as well as applications need to be modified to call the services In order for an SOA project to be successful the project must obtain company and management support in order to gain the proper exposure, funding, and attention. If SOA is new to a company they must also support the proper training in order for the project to be designed, and implemented correctly. References: Tews, R. (2007).

• Issue about mapping MAC address to Ipv6 address

  - by deepsky

  I know that the address in ipv6 with prefix range 001 to 111 should use a 64-bit interface identifier that follows the EUI-64 format, which translates the MAC to ipv6 as below. MAC:00-02-b3-1e-83-29 --> 02-02-b3-ff-fe-1e-83-29 --->ipv6 addr: fe80::202:b3ff:fe1e:8329 Then I checked my network status with ipconfig /all on my windows XP, but it seems my ipv6 address doesn't follow the above rule: MAC:00-24-81-XX-XX-XX ipv6 addr:2001:da8:8006:225:0:24:81XX:XXXX Obviously it doesn't follow the EUI-64 format. Instead it just directly use the MAC as the last 8 bytes. Anyone know the reason? Pls Correct me if I am wrong.

• Configure iptables with a bridge and static IPs

  - by Andrew Koester

  I have my server set up with several public IP addresses, with a network configuration as follows (with example IPs): eth0 \- br0 - 1.1.1.2 |- [VM 1's eth0] | |- 1.1.1.3 | \- 1.1.1.4 \- [VM 2's eth0] \- 1.1.1.5 My question is, how do I set up iptables with different rules for the actual physical server as well as the VMs? I don't mind having the VMs doing their own iptables, but I'd like br0 to have a different set of rules. Right now I can only let everything through, which is not the desired behavior (as br0 is exposed). Thanks!

• Debian 5.0.8 won't detect my ethernet adapter

  - by PaulH

  I'm installing Debian 5.0.8 on a Dell Latitude E6410 using the network install x86 CD. Unfortunately, it won't detect my Ethernet adapter. Specifically, I get the error: No Ethernet card was detected. If you know the name of the driver needed by your Ethernet card, you can select it from the list. lspci shows: 00:19.0 Ethernet controller: Intel Corporation Device 10ea (rev 05) That should correspond to the e100e driver. But, if I select it from the list, the install CD still fails to detect it. Ubuntu 10.10 and Windows 7 are able to use this device with no problem. Does anybody know what I can do to make Debian use my Ethernet adapter? Thanks, PaulH

• Best Practice: Migrating Email Boxes (maildir format)

  - by GruffTech

  So here's the situation. I've got about 20,000 maildir email accounts chewing up a several hundred GB of space on our email server. Maildir by nature keeps thousands of tiny a** little files, instead of one .mbox file or the like... So i need to migrate all of these several millions of files from one server to the other, for both space and life-cycle reasons. the conventional methods i would use all work just fine. rsync is the option that comes immediately to mind, however i wanted to see if there are any other "better" options out there. Rsync not handling multi-threaded transfers in this situation sucks because it never actually gets up to speed and saturates my network connection, because of this the transfer from one server to another will take hours beyond hours, when it shouldn't really take more then one or two. I know this is highly opinionated and subjective and will therefore be marked community wiki.

• Lost support for Web Access on Verizon BlackBerry World Edition

  - by Jimsmithkka

  Hello all, I believe that some silliness has occurred with my blackberry after a OS upgrade. I have 2010 Blackberry world edition phone, purchased off a friend who went iPhone, that at first worked with web on the Verizon network. When i connected it to my PC to transfer contacts, it prompted for an OS upgrade, which I performed. Post-Upgrade I have found that i can no longer access any of the web services: eg. AppWorld, Email, Twitter, Browser. And they all state that i need to upgrade my account to gain access. I had a Storm previous to this that worked fine, and at the VZ store they told me this device is no longer supported (new in 2010 though), and they got me a free "upgrade" to the Blackberry flip. What i could use help with is finding a source stating it is discontinued or a guide that will help me re-enable the web features. I can provide further info later if needed (currently at work with the flip, the WorldEdition is at home).

• Resized NTFS partition, now it wont mount.

  - by H4Z3Y

  I have had a 1.5TB drive used as an external for 6 months or so, then I decided to put it in my linux server for network storage. ntfs was being crazy inefficient so I wanted to change the filesystem to ext4. I used the ntfsresize command to reduce the partition to 650GB and that took abour 2 hours, then I deleted all of the entries in fstab like a guide told me too and created a new one the size of the ntfs partition, or, 650GB. after I modified fstab the ntfs partition would no longer mount and when plugging it in to windows it says "This Hard Drive needs to be formatted". any ideas on how I can recover the data off of the drive? I have 600GB of free space on a different drive so I just need some way of copying them off.

• Computers displaying an unwanted password change prompt

  - by evesirim

  We run a small network of users from a central SBS 2008 server that handles group policy & AD. Most of our users operate under a policy that propts them for a password change every 6 months as a security measure, with a few administrator accounts & terminal machines not using the policy for the sake of ease as they are needed all the time. Recently all machines regardless of policy have started asking for a password change out of schedule. Some PCs run Windows 7 & some XP, though the password prompts don't seem to discriminate between OS. What could this be down to? Many thanks
