• How do I enable the confluence-users group?

  - by M. Joanis

  I've got an issue with Atlassian Confluence. Normal users can't log in, but administrators can... Details below! I manage users using an Apple Open Directory (LDAP). I created two groups: "confluence-administrators" and "confluence-users". I've added team leaders and managers to both groups, and I've added some users to "confluence-users". Everyone in "confluence-administrators" can log in easily. People in "confluence-users" can't log in at all. When I look at the user list (in Confluence), and select a user to examine the list of groups he or she belongs to, I can see that the Confluence Administrators are indeed members of the "confluence-administrators" group, but not a single user is a member of the "confluence-users" group. Not event the Confluence Administrators, which are members of both groups! So I tried to have one of the "confluence-users" log in while watching the Confluence logs. Here's the result: 2012-07-05 14:50:19,698 ERROR [http-8090-11] [core.event.listener.AutoGroupAdderListener] handleEvent Could not auto add user to group: Group <confluence-users> is read-only and cannot be updated at com.atlassian.crowd.directory.DbCachingRemoteDirectory.addUserToGroup(DbCachingRemoteDirectory.java:461) ... So it says the group group is read-only... I'm not sure why it is a problem. Well confluence-administrators too is read-only and it doesn't complain. Some things I don't think are part of the problem: I've synchronized Confluence with LDAP many, many times. I have verified many times that I didn't make a typo while setting the groups on the LDAP server. LDAP synchronization goes well. No errors in the logs (only INFO level log messages). The user exists. Errors in the logs are different when a user doesn't exist. Any help is most welcome!

• Nginx dynamic upstream configuration / routing

  - by Dan Sosedoff

  I was experimenting with dynamic upstream configuration for nginx and cant find any good solution to implement upstream configuration from third-party source like redis or mysql. The idea behind it is to have a single file configuration in primary server and proxy requests to various app servers based on environment conditions. Think of dynamic deployments where you have X servers that are running Y workers on different ports. For instance, i create a new app and deploy. App manager selects a server and then rolls out a worker (Ruby/PHP/Python) and then reports the ip:port to the central database with status "up". At this time when i go to the given url nginx should proxy all requests to the specified ip:port upstream. The whole thing is pretty similar to what heroku does, except this proof-of-concept is not supposed to be production ready, mostly for internal needs. The easiest solution i found was using resolver with ruby-based DNS server. It works, nginx gets the IP address correctly, but the only problem is that you cant define port number for that IP. Second solution (which i havent tried yet) is to roll something else as a proxy server, maybe written in Erlang. In this case we need to use something to serve static content. Any ideas how to implement this in more flexible and stable way? P.S. Some research options: http://openresty.org/#DynamicRoutingBasedOnRedis https://github.com/nodejitsu/node-http-proxy

• Asus P5Q doesn't post at all

  - by Sebi

  I had a very strange incident this evening. I was watching TV on the computer and suddenly the sound stutter. Some seconds later, the screen went black. First I thought ok some error, don't worry. Since the computer didn't react on any input from the mouse or keyboard, I shutted it down by pressing the power button. I tried to reboot but the monitor rest black. All the fans were running, the MB didn't made a beep and the leds are all green as they have to be. The HDD is running too, also the monitor is on. But nothing happens, not even a single message on the screen, just black. Here are the things I already tried with no success: tried to boot with 1 of two rams (each tested alone) turned off all power (pull th plug) for 10 minutes tested the graphic card with another pc. there it worked. tested the RAM with another pc. there it worked. Any hints what to do next?

• How to scope access to a service to set of users, using OpenLDAP, and only OUs

  - by JDS

  Okay, here goes. Solving this will solve several problems for me (as I can reapply this knowledge to several extant, similar problems), but luckily I have a very specific, concise problem to describe. Enough preamble. Our hosting partner is setting up VPN access for us and is connecting it to our LDAP server. They are using Cisco VPN, the docs on setting this up are here: http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a00808c3c45.shtml#maintask1 Specifically, note the screenshot in (5), under "ASDM" Now, I do NOT want to provide access to all of our users. I only want to provide access to our IT group. But I do not see a configuration option for LDAP groups on that web reference for the Cisco VPN. We are using: OpenLDAP 2.4 Static groups (i.e. "Group has the following members...") Single user OU, "ou=users,dc=mycompany,dc=com" Is it possible to provide an alias of some kind in OpenLDAP that creates another OU, "itusers", say, and lets me alias the members of that OU somehow? Something like: "cn=Jeff Silverman,ou=itusers,dc=mycompany,dc=com" is an alias for "cn=Jeff Silverman,ou=users,dc=mycompany,dc=com" And is NOT a separate, unique user account. Alternatively, should I just create a separate OU and manage it separately? It is a pain, but only 12-15 users will have to be managed that way, with two separate user accounts. But I hate this option - messy, unmanageable, unscalable. You know what I mean. I am open to any options. I've searched and read all over but I can't quite find an directly analagous example. I can't possibly be the only one who's had this problem! Thanks!

The webserver run just fine when we use the phpinfo.php test file. However as soon as I point it to my apps, nothing comes up. Check the error.log file and there's no error. Very mind boggling. I spent over 1 week trying to figure it out with no luck.. Please help?

• Last (I think and hope) problems configuring SSL certificate with Apache and VirtualHosts

  Finally I set apache2 to get a single certificate for all subdomains. [...] # Go ahead and accept connections for these vhosts # from non-SNI clients SSLStrictSNIVHostCheck off # Apache setup which will listen for and accept SSL connections on port 443. Listen 443 # Listen for virtual host requests on all IP addresses NameVirtualHost *:443 # Because this virtual host is defined first, it will # be used as the default if the hostname is not received # in the SSL handshake, e.g. if the browser doesn't support # SNI. <VirtualHost *:443> ServerName domain.localhost DocumentRoot "/Users/<my_user_name>/Sites/domain/public" <Directory "/Users/<my_user_name>/Sites/domain/public"> Order allow,deny Allow from all </Directory> # SSL Configuration SSLEngine on ... </VirtualHost> <VirtualHost *:443> ServerName subdomain1.domain.localhost DocumentRoot "/Users/<my_user_name>/Sites/subdomain1/public" <Directory "/Users/<my_user_name>/Sites/subdomain1/public"> Order allow,deny Allow from all </Directory> # SSL Configuration SSLEngine on ... </VirtualHost> <VirtualHost *:443> ServerName subdomain2.domain.localhost DocumentRoot "/Users/<my_user_name>/Sites/subdomain2/public" <Directory "/Users/<my_user_name>/Sites/subdomain2/public"> Order allow,deny Allow from all </Directory> # SSL Configuration SSLEngine on ... </VirtualHost> So, for example, I can correctly access https://subdomain1.domain.localhost https://subdomain2.domain.localhost ... Now, anyway, I have problems on accessing http://subdomain1.domain.localhost http://subdomain2.domain.localhost ... Since I use a Mac Os, on accessing the "http: version", I get a default page "Your website." (instead of a error). Why does it happen?

• How do you guys handle custom yum repository?

  - by luckytaxi

  I have a bunch of tools (nagios, munin, puppet, etc...) that gets installed on all my servers. I'm in the process of building a local yum repository. I know most folks just dump all the rpms into a single folder (broken down into the correct path) and then run createrepo inside the directory. However, what would happen if you had to update the rpms? I ask because I was going to throw each software into its own folder. Example one, put all packages inside one folder (custom_software) /admin/software/custom_software/5.4/i386 /admin/software/custom_software/5.4/x86_64 /admin/software/custom_software/4.6/i386 /admin/software/custom_software/4.6/x86_64 What I'm thinking of ... /admin/software/custom_software/nagios/5.4/i386 /admin/software/custom_software/nagios/5.4/x86_64 /admin/software/custom_software/nagios/4.6/i386 /admin/software/custom_software/nagios/4.6/x86_64 /admin/software/custom_software/puppet/5.4/i386 /admin/software/custom_software/puppet/5.4/x86_64 /admin/software/custom_software/puppet/4.6/i386 /admin/software/custom_software/puppet/4.6/x86_64 Ths way, if I had to update to the latest version of puppet, I can save manage the files accordingly. I wouldn't know which rpms belong to which software if I threw them into one big folder. Makes sense?

• IPCop Packet Mangling

  - by Zenham

  I've found myself in a pickle replacing an old firewall for a client this afternoon. I'm configuring their new IPCop firewall (1.4.21), Zerina OpenVPN addon is installed. What I need to do: There are three network interfaces, currently set up as red (WAN), green (LAN, 192.168.20.0/24) and orange (remote network 10.1.20.0/24). The orange interface is a direct fiber link to another organization. Simple description: Traffic and networks appear to be properly configured at this point, but I have many (150+) specific IPs on the LAN which, when accessing the resources on the 10.1.20.x network, need to be mangled to appear to be coming from the 10.1.20.0/24 network (and return traffic properly delivered). The routing on the far side was configured earlier and should be fine, but I need to redirect any packets coming across destined for those IPs to end up at their proper destination. The addressing is fixed and predictable (ie. 192.168.20.125 - 10.1.20.125). I need to insert whatever rules I have into the IPCop ruleset through /etc/rc.local I know, I'm just not sure about how I should structure this. There's CUSTOMOUTPUT and CUSTOMINPUT targets, both which currently just consist of the single rule redirecting packets to the OVPNOUTPUT/OVPNINPUT targets, so I'm guessing I should insert a rule matching outbound packets destined for the 10.1.20.x network and redirecting to a new target (maybe called TO-ORANGE) and a rule at the top of CUSTOMINPUT which redirects to a FROM-ORANGE target. Under those targets, I would have rules which do the IP matching and mangling. Am I approaching this right? If so, I'm not very familiar with mangle, and would appreciate seeing examples of how to write that source-IP rewrite. If not, how would you suggest doing this? TIA! edit: I notice additionally that the nat table has CUSTOMPREROUTING and CUSTOMPOSTROUTING targets, I guess I could alternatively post the rules in there....

• Multiple contacts with shared information

  - by Keith Thompson

  Background: I currently have several hundred contacts, synchronized between a Microsoft Exchange server and several mobile devices. I also save exported copies of the contacts in .vcf format. Is there a good way (application, file format, whatever) to maintain contacts with shared information? A very common scenario is that I have contacts for two or more people who live in the same house, for example: John Doe 123 Main Street, Anytown USA Home: 555-555-1111 Work: 555-555-2222 Mobile: 555-555-3333 E-mail: [email protected] Jane Doe 123 Main Street, Anytown USA Home: 555-555-1111 Work: 555-555-4444 Mobile: 555-555-5555 E-mail: [email protected] As you can see, both contacts have the same home address and phone number, but distinct names and work and mobile phone numbers. (Other information might also be either shared or distinct.) The applications and file formats I'm familiar with don't seem to have a good way to deal with this. If I use a single "John & Jane Doe" contact for both, it's difficult to distinguish the distinct information (if I want to call Jane's mobile phone rather than John's). If I use a separate contact for each, I have to remember to update both of them (or all of them for N 2) when they move or change their home phone number. An ideal solution would let me create a record containing information for their household, and have each of their contact records contain a reference to the household record, so that when I view John's contact record I see both shared and distinct information. Is there anything out there that has good support this kind of thing? (I would think there would be, since it's a very common scenario.) (I suppose I could roll my own system that generates merged .vcf files from some extended format, but that wouldn't play well with synchronizing across multiple devices.)

• Advice needed: ADSL and VPN for a small company

  - by Saajid Ismail

  Hi. I need advice on purchasing an ADSL modem/router for a small company. At the moment, we are using the iBurst Wireless service for internet connectivity. I have the iBurst desktop modem, which connects to my Netgear WNR2000 router via ethernet. I am using the Netgear WNR2000 to deploy a wireless network as well. I have also set up a VPN using Windows Server 2003, and enabled the VPN Passthrough settings on the Netgear router. I am able to connect to the office network remotely without difficulty. However the problem that I've read is that the Netgear WNR2000 only supports VPN passthrough for a single session. This is simply not good enough. I need to be able to support at least 3 concurrent VPN connections immediately, and up to 5 in the near future. Now I am cancelling my iBurst Wireless service and have just got my ADSL line installed. I have to purchase an ADSL modem, and now is a good time to think of future proofing my investment. I need a good ADSL modem, that will allow me to support at least 5 concurrent VPN connections, or more, without breaking the bank. My budget is about 150-200 USD. I believe that my current Netgear WNR2000 router will be useless, except maybe to extend my wireless network in the future by a bit. Is there a solution where I can still use my Netgear WNR2000 for WiFi, for e.g., by connecting a cheaper non-WiFi ADSL modem to the Netgear router? If not, then which WiFi-enabled ADSL modem/router that supports at least 5 VPN passthroughs can you recommend? To sum it up, I need an ADSL modem/router that is: ADSL & ADSL2+ compatible has built-in 802.11n 270/300mbps WiFi (if having this feature doesn't push the price up too much) supports at least 5 VPN connections using VPN passthrough EDIT: Answer 2.10 in the following FAQ has me a bit worried - What is VPN/multiple VPN Pass-through?

• Windows NT from vmware to kvm

  - by Luca Rossi

  I'm trying to convert a couple of old Windows NT virtual servers from vmware to KVM. I tried almost all guidelines and how to I found around the web but with no luck. I have the vmware virtual disk: Dlc1.vmdk partitioned image. I converted the vmdk into qcow2 image with the qemu utility and I tried to use it with kvm: kvm -hda test.qemu -vnc :1 -m 750 but I receive "error loading operating system" I also tried with raw partitions I can mount through losetup and kpartx. but nothing changed I also tried to create an brand new image file with: qemu-img create -f qcow2 test.qcow2 2G I partitioned the new image file and I copied the original partition 1 to the new partition 1 with dd: dd if=/dev/mapper/loop1p1 of=/dev/mapper/loop0p1 bs=128M no luck again I also tried with a single unpartitioned file: qemu-img create -f qcow2 test.qcow2 2G and I copied the partition 1 to the new image file: dd if=/dev/mapper/loop0p1 of=test.img bs=128M but when booting, I receive a black screen and the virtual machine hangs. The bootloader is loaded successfully, because I also tried with a GRUB live iso and I receive the same screens and errors. Note that grub sees the Windows setup and give me the boot choice. I have the suspect the problem is that the vmware machine is probably a scsi guest and in centos 6 (my system) scsi emulation is no longer supported. But in that case, where to change in Windows? I'm not so skilled with MS systems. Thank you for the help Luca Rossi

• Can't access IIS 7 server URL from the same IIS 7 server.

  - by Kevin Raffay

  We have an intranet site ie, xxx.yyyy.com, that users access by entering "http"://xxx.yyy.com. Our problems started when we migrated to IIS 7 running on a new 2003 server. We got rid of our single-sign on code and implemented a security model where we capture a user's domain credentials which we then authenticate against a DB. In order to get the domain credentials passed to our ASP.NET app, we have the following settings: Anonymous Authentication:Disabled ASP.NET Impersonation: Enabled Basic/Digest/Forms Authentication: Disabled Windows Authentication: Enabled We allow "*" and deny "?" in the web.config. Browsing "http"://xxx.yyy.com from any client PC results in a domain login prompt, and if your enter a proper user/pwd, you can get in. However, browsing "http"://xxx.yyy.com while remoting into the server results in 3 domain login prompts and eventually a 401 error - unauthorized. We have traced this behavior to problems with our web site where we have pages doing "screen scraping" using the HttpRequest calling a url on the same server. When doing a HttpRequest from any other client, using a test harness that passes authorized credentials, all is good. So internal HttpRequest calls on the server fail, just like attempts to browse that server's url from within a remote session. Why would a to "http"://xxx.yyy.com on server xxx.yyy.com fail authentication?

• best practice to removing DC from Site that no longer connects via vpn in another city

  - by dasko

  hi i am looking for a recap of what i have done already to see if i missed anything. i had two cities connected by wan using a ipsec persistent tunnel between gateways. i had one DC (DOMAIN CONTROLLER) in each city that was a global catalog server (GC) they were set up to replicate and i had them configured under Sites and Servers with their own subnet etc... about 6 months ago the one city was removed and i was not able to gracefully remove, through dcpromo, the server that was there. it is no longer used and cannot be brought back. the company went from two sites down to single site. Problem is i had a whole bunch of kcc errors and replication bugs in the event viewer. i wanted to clean up my active directory and decided to use the ntdsutil metadata cleanup commands. i removed the server from the specifed site based on a procedure from petri website. I then removed the instances of the old DC and site from Sites and Servers. Then i went and cleaned up the DNS by removing Host A records, NS server name from both the local DNS forward lookup zone and the _msdcs i also removed the reverse lookup zone for the subnet that no longer exists. is there anything i missed? thanks in advance for any help. gd

• Kerberos & signle-sign-on for website

  - by Dylan Klomparens

  I have a website running on a Linux computer using Apache. I've employed mod_auth_kerb for single-sign-on Kerberos authentication against a Windows Active Directory server. In order for Kerberos to work correctly, I've created a service account in Active Directory called dummy. I've generated a keytab for the Linux web server using ktpass.exe on the Windows AD server using this command: ktpass /out C:\krb5.keytab /princ HTTP/[email protected] /mapuser [email protected] /crypto RC4-HMAC-NT /ptype KRB5_NT_PRINCIPAL /pass xxxxxxxxx I can successfully get a ticket from the Linux web server using this command: kinit -k -t /path/to/keytab HTTP/[email protected] ... and view the ticket with klist. I have also configured my web server with these Kerberos properties: <Directory /> AuthType Kerberos AuthName "Example.com Kerberos domain" KrbMethodK5Passwd Off KrbAuthRealms EXAMPLE.COM KrbServiceName HTTP/[email protected] Krb5KeyTab /path/to/keytab Require valid-user SSLRequireSSL <Files wsgi.py> Order deny,allow Allow from all </Files> </Directory> However, when I attempt to log in to the website (from another Desktop with username 'Jeff') my Kerberos credentials are not automatically accepted by the web server. It should grant me access immediately after that, but it does not. The only information I get from the mod_auth_kerb logs is: kerb_authenticate_user entered with user (NULL) and auth_type Kerberos However, more information is revealed when I change the mod_auth_kerb setting KrbMethodK5Passwd to On: [Fri Oct 18 17:26:44 2013] [debug] src/mod_auth_kerb.c(1939): [client xxx.xxx.xxx.xxx] kerb_authenticate_user entered with user (NULL) and auth_type Kerberos [Fri Oct 18 17:26:44 2013] [debug] src/mod_auth_kerb.c(1031): [client xxx.xxx.xxx.xxx] Using HTTP/[email protected] as server principal for password verification [Fri Oct 18 17:26:44 2013] [debug] src/mod_auth_kerb.c(735): [client xxx.xxx.xxx.xxx] Trying to get TGT for user [email protected] [Fri Oct 18 17:26:44 2013] [debug] src/mod_auth_kerb.c(645): [client xxx.xxx.xxx.xxx] Trying to verify authenticity of KDC using principal HTTP/[email protected] [Fri Oct 18 17:26:44 2013] [debug] src/mod_auth_kerb.c(1110): [client xxx.xxx.xxx.xxx] kerb_authenticate_user_krb5pwd ret=0 [email protected] authtype=Basic What am I missing? I've studied a lot of online tutorials and cannot find a reason why the Kerberos credentials are not allowing access.

• mdadm superblock hiding/shadowing partition

  - by Kjell Andreassen

  Short version: Is it safe to do mdadm --zero-superblock /dev/sdd on a disk with a partition (dev/sdd1), filesystem and data? Will the partition be mountable and the data still there? Longer version: I used to have a raid6 array but decided to dismantle it. The disks from the array are now used as non-raid disks. The superblocks were cleared: sudo mdadm --zero-superblock /dev/sdd The disks were repartitioned with fdisk and filesystems created with mfks.ext4. All disks where mounted and everything worked fine. Today, a couple of weeks later, one of the disks is failing to be recognized when trying to mount it, or rather the single partition on it. sudo mount /dev/sdd1 /mnt/tmp mount: special device /dev/sdd1 does not exist fdisk claims there to be a partition on it: sudo fdisk -l /dev/sdd Disk /dev/sdd: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xb06f6341 Device Boot Start End Blocks Id System /dev/sdd1 1 243201 1953512001 83 Linux Of course mount is right, the device /dev/sdd1 is not there, I'm guessing udev did not create it because of the mdadm data still on it: sudo mdadm --examine /dev/sdd /dev/sdd: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : b164e513:c0584be1:3cc53326:48691084 Name : pringle:0 (local to host pringle) Creation Time : Sat Jun 16 21:37:14 2012 Raid Level : raid6 Raid Devices : 6 Avail Dev Size : 3907027120 (1863.02 GiB 2000.40 GB) Array Size : 15628107776 (7452.06 GiB 8001.59 GB) Used Dev Size : 3907026944 (1863.02 GiB 2000.40 GB) Data Offset : 2048 sectors Super Offset : 8 sectors State : clean Device UUID : 3ccaeb5b:843531e4:87bf1224:382c16e2 Update Time : Sun Aug 12 22:20:39 2012 Checksum : 4c329db0 - correct Events : 1238535 Layout : left-symmetric Chunk Size : 512K Device Role : Active device 3 Array State : AA.AAA ('A' == active, '.' == missing) My mdadm --zero-superblock apparently didn't work.

• HAProxy + NodeJS gets stuck on TCP Retransmission

  - by sled

  I have a HAProxy + NodeJS + Rails Setup, I use the NodeJS Server for file upload purposes. The problem I'm facing is that if I'm uploading through haproxy to nodejs and a "TCP (Fast) Retransmission" occurs because of a lost packet the TX rate on the client drops to zero for about 5-10 secs and gets flooded with TCP Retransmissions. This does not occur if I upload to NodeJS directly (TCP Retransmission happens too but it doesn't get stuck with dozens of retransmission attempts). My test setup is a simple HTML4 FORM (method POST) with a single file input field. The NodeJS Server only reads the incoming data and does nothing else. I've tested this on multiple machines, networks, browsers, always the same issue. Here's a TCP Traffic Dump from the client while uploading a file: ..... TCP 1506 [TCP segment of a reassembled PDU] >> everything is uploading fine until: TCP 1506 [TCP Fast Retransmission] [TCP segment of a reassembled PDU] TCP 66 [TCP Dup ACK 7392#1] 63265 > http [ACK] Seq=4844161 Ack=1 Win=524280 Len=0 TSval=657047088 TSecr=79373730 TCP 1506 [TCP Retransmission] [TCP segment of a reassembled PDU] >> the last message is repeated about 50 times for >>5-10 secs<< (TX drops to 0 on client, RX drops to 0 on server) TCP 1506 [TCP segment of a reassembled PDU] >> upload continues until the next TCP Fast Retransmission and the same thing happens again The haproxy.conf (haproxy v1.4.18 stable) is the following: global log 127.0.0.1 local1 debug maxconn 4096 # Total Max Connections.

• SCCM 2012 - some remote clients unable to download some applications, 401.2 error

  - by growse

  I've got a small SCCM 2012 deployment with about 35 clients attached. Most of these clients are in the same network as the single SCCM host, but three are about 1000 miles away. Oddly, these three clients have stopped being able to download some application packages over BITS. Publishing a new package works for all the other clients, but for these three it never seems to download. If I go to the software centre, it just hangs at "0% downloaded". On the client, the DataTransfer.log says (repeatedly): CDTSJob::HandleErrors: DTS Job '{2DCBBB4C-6D84-479A-9218-885B72C834B9}' BITS Job '{E78147DD-4A26-4942-B4FD-6EC3EB77EECD}' under user 'S-1-5-18' OldErrorCount 442 NewErrorCount 443 ErrorCode 0x80072EE2 DataTransferService 30/07/2012 09:27:41 2964 (0x0B94) CDTSJob::HandleErrors: DTS Job ID='{2DCBBB4C-6D84-479A-9218-885B72C834B9}' URL='http://sccm-host:80/SMS_DP_SMSPKG$/Content_3e7f6982-6346-4f27-ae00-ad5dcb391455.1' ProtType=1 DataTransferService 30/07/2012 09:27:41 2964 (0x0B94) Cas.log says (repeatedly): Location update from CTM for content Content_3e7f6982-6346-4f27-ae00-ad5dcb391455.1 and request {AD041FCB-03D2-4FE6-A6FA-38A6B80FB2A1} ContentAccess 30/07/2012 08:33:39 5048 (0x13B8) Download location found 0 - http://lonsbrndsccm02.mcs.int.thomsonreuters.com/SMS_DP_SMSPKG$/Content_3e7f6982-6346-4f27-ae00-ad5dcb391455.1 ContentAccess 30/07/2012 08:33:39 5048 (0x13B8) Download request only, ignoring location update ContentAccess 30/07/2012 08:33:39 5048 (0x13B8) On the server, I've enabled failed request log tracing.

Some other packages seem to work fine, the daily anti-malware delta gets downloaded and patched without issue. Why are these packages failing?

• How come the ls command prints in multiple columns on tty but only one column everywhere else?

  - by David Lou

  Even after using Unix-like OSes for a couple years, this behaviour still baffles me. When I use the ls command in a directory that has lots of files, the output is usually nicely formatted into multiple columns. Here's an example: $ ls a.txt C.txt f.txt H.txt k.txt M.txt p.txt R.txt u.txt W.txt z.txt A.txt d.txt F.txt i.txt K.txt n.txt P.txt s.txt U.txt x.txt Z.txt b.txt D.txt g.txt I.txt l.txt N.txt q.txt S.txt v.txt X.txt B.txt e.txt G.txt j.txt L.txt o.txt Q.txt t.txt V.txt y.txt c.txt E.txt h.txt J.txt m.txt O.txt r.txt T.txt w.txt Y.txt However, if I try to redirect the output to a file, or pipe it to another command, only a single column appears in the output. Using the same example directory as above, here's what I get when I pipe ls to wc: $ ls | wc 52 52 312 In other words, wc thinks there are 52 lines, even though the output to the terminal has only 5. I haven't observed this behaviour in any other command. Would you like to explain this to me?

• 3GB RAM Installed and Detected by BIOS, Windows Vista 32bit Only Sees 2GB

  - by Nathan Taylor

  I am attempting to install more RAM on a Windows Vista 32bit machine which is using a X6DAL-XG motherboard and the RAM amount reported in the BIOS is 3GB+, but Windows is only reporting 2GB installed. The motherboard has 6 RAM bays which I have populated with various combinations of 4 1GB sticks, and 2 512mb sticks, but no matter how I configure them Windows doesn't see more than 2GB. I realize of course 32-bit Windows has a 3gb cap on memory, but that doesn't explain why it will only report 2GB when there are in fact (currently) 5GB installed. I should think I would be able to see at least 3GB. According to the spec list for the motherboard the minimum RAM requirements are DDR333/266mhz installed in pairs. I have done this exactly, and the BIOS isn't reporting any problems at POST. RAM Configuration (according to CPU-Z): Slot #1: Kingston 128mx72D266C25 - 1024mb PC2100 (133mhz) Slot #2: Kingston KVR266X72RC25/1024 - 1024mb PC2100 (133mhz) Slot #3: PQI - 512mb PC2700 (166mhz) Slot #4: Kingston 128mx72D266C25 - 1024mb PC2100 (133mhz) Slot #5: Kingston KVR266X72RC25/1024 - 1024mb PC2100 (133mhz) Slot #6: PQI - 512mb PC2700 (166mhz) I'm not sure if memory specs above conflict with this statement in the motherboard manual or not: Memory Support The X6DAL-XG supports up to 12GB/24GB of registered ECC DDR333/266 (PC2700/PC2100) memory. The motherboard was designed to support 4GB (PC2100) modules in each slot, but only the 2GB modules have been tested. When using registered ECC DDR333 (PC2700) memory, installing four pieces of double-banked memory or six pieces of single-banked memory is supported. So, am I doing something wrong with the RAM I have now, or is there some sort of compatibility problem which I am missing? Thanks!

• How to generate customized sudoers files in puppet depending on the environment they're deployed to?

  - by gozu

  the sysadmins are present in the sudoers files of all environments, but other sudoers are not. Different environments all have slightly different sudoers. Most of the time, 90% of users are the same, and 10% vary so we cannot have only one sudoers file for everything. Right now, we are using puppet with 10 different files with names like sudoers.production1, sudoers.production2, sudoers.production3, sudoers.testing1, sudoers.staging1 and so forth. Puppet then picks the file to deploy based on the server's $domain (ex: dbserver.staging1.acme.com) or $hardwaremodel. It works fine but it's a nightmare to maintain so many files. I'd like to autogenerate sudoers files based on the server's domain and have only one big file with all the sudoers permissions for all users and all environments. Something that looks like: User_Alias ADMINS = abe, bob, carol, dave case $domain { "staging1.acme.com" { #add dev1,dev2,tester1,tester2 to sudoers file } "testing2.acme.com" { #add tester1, tester3, tester4 to sudoers file } What's the best way to go about this? Suggestions for alternatives are welcome. I'd appreciate any tips. Update 1: For security reasons, we'd rather not concatenate a bunch of files from a folder located on a puppet client in case someone puts a file in there (maliciously or not) and either breaks the combined file or inserts something in it. Most importantly, for usability, we'd like to keep the number of sudoers related files (fragment or complete) on puppet server to either 3 (prod/stage/test) or preferably 1 file. this file would (somehow) generate sudoers files on the puppet server and send one customized file to each puppet client. The purpose of this would be only searching for a username in a single file and removing it quicker than doing it on 11 files. When adding a user to a bunch of environments, it won't be as quick, but only one file would need to be opened and looked at, greatly reducing the chances of an omission. our Sudo version is 1.6.9p8 so we can't use /sudoers.d folder, only a sudoers file.

• on debian, lighttpd apache2 using 80 port, lighttpd throws :address already use error

  - by user1960581

  I bought the linode(linode.com) server the other day. I've been trying to run lighttpd and apache2 at the same port, using lighttpd for static files. As linode is only providing ONE ipv4 address, I tried to bind lighttpd on the ipv6 address.

• Apache Caching and Expires configuration

  - by mcondiff

  I'm looking for a best possible caching/expires configuration for my specific situation. I realize that some sites have advocated turning etags off: Header unset ETag, FileETag None I know that I should use either Expires or Cache-Control. In additions, I know that I should use either Last-modified or ETAGs (Per ySlow docs). I inherited a clients server that uses the following in .htaccess: <FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf|xml|txt|html|htm)$"> Header set Cache-Control "max-age=172800, public, must-revalidate" </FilesMatch> With this server I am not going to be able to rely on staff to rename images, css and js in web applications so I do not want to set the expires far in the future without knowing (with a good certainty) that "most/all" browsers will check to see if content has changed. What I do not want to happen is someone call me and say the website is broken because they replaced an image and it's not showing up. But I do want to take the most advantage I can with caching and expires while still maintaining that mostly all browsers will check with the server to see if components have changed. I have access to both the .htaccess and apache .conf file and it is a single server, the content is not deployed on multiple servers. What would be the best .htaccess or .conf configuration for me to achieve my goals for this clients server? Thanks for your help

• Does any Certificate Authority support both SAN and wildcards?

  - by nicholas a. evans

  My basic quandry is that wildcard certificates don't support subdomains of subdomains, nor do they help with alternate domain names. Basically, if my CN is example.com, I want a Subject Alternative Name field that looks roughly like so: DNS:example.com DNS*.example.com DNS:*.beta.example.com DNS:example.net DNS:*.example.net DNS:*.beta.example.net Using a self-signed cert, I verified that the browsers will work just fine with this. Unfortunately, none of the Certificate Authorities that I looked into (Thawte, GoDaddy, Verisign, Digicert) seemed to support both wildcard certs and Subject Alternative Name (sometimes referred to as "Multiple Domain UCC"). I even called up GoDaddy tech support to confirm. Is there a CA (trusted by 99% of browsers) that supports wildcards for the Subject Alternative Name? One little restriction: I'm saddled with Amazon EC2's single Elastic IP per instance limitation. Here are what I see as my backup plans: set up three extra EC2 instances, each configured for a different IP address and cert, and nginx reverse proxy from three of them into the app server(s) introduces latency(?), and even the cheapest EC2 instance isn't that cheap instead of dedicated reverse proxy instances, setup the four or more almost identical EC2 app servers, with nginx using the port to determine which cert to deliver, and use haproxy to distribute the traffic amongst themselves. complicated to configure and manage? I'm not using the cheapest EC2 instance type for my app servers. If I don't need 4+ app servers for the load, it raises the cost. set up an external server (outside of EC2) that doesn't have EC2's Elastic IP address restrictions, setup all of the alternate IP addresses and certificates on that server, and nginx reverse proxy from that server into the EC2 app servers. extra IP addresses are almost free (still need to pay for the server of course), but don't come with the robust "elasticity" that Amazon's Elastic IPs provide. even more latency than in the first scenario. Are these approaches crazy or reasonable? Do you have another one to suggest?

• Strange performance issue with Dell R7610 and LSI 2208 RAID controller

  - by GregC

  Connecting controller to any of the three PCIe x16 slots yield choppy read performance around 750 MB/sec Lowly PCIe x4 slot yields steady 1.2 GB/sec read Given same files, same Windows Server 2008 R2 OS, same RAID6 24-disk Seagate ES.2 3TB array on LSI 9286-8e, same Dell R7610 Precision Workstation with A03 BIOS, same W5000 graphics card (no other cards), same settings etc. I see super-low CPU utilization in both cases. SiSoft Sandra reports x8 at 5GT/sec in x16 slot, and x4 at 5GT/sec in x4 slot, as expected. I'd like to be able to rely on the sheer speed of x16 slots. What gives? What can I try? Any ideas? Please assist Cross-posted from http://en.community.dell.com/support-forums/desktop/f/3514/t/19526990.aspx Follow-up information We did some more performance testing with reading from 8 SSDs, connected directly (without an expander chip). This means that both SAS cables were utilized. We saw nearly double performance, but it varied from run to run: {2.0, 1.8, 1.6, and 1.4 GB/sec were observed, then performance jumped back up to 2.0}. The SSD RAID0 tests were conducted in a x16 PCIe slot, all other variables kept the same. It seems to me that we were getting double the performance of HDD-based RAID6 array. Just for reference: maximum possible read burst speed over single channel of SAS 6Gb/sec is 570 MB/sec due to 8b/10b encoding and protocol limitations (SAS cable provides four such channels).

• Tools to (privately) annotate/markup a website for maintenance

  - by rob

  I've been tasked with updating a website. Rather than proofreading and updating each page (one at a time), I want to make a single pass over the entire website, marking graphics/images/videos that need to be rewritten, removed, or updated. I thought about taking screenshots, marking those up, and putting them in our bug-tracking database, but that seems like an extremely tedious solution. Some of the content is similar on various pages across the website, and the entire site itself is localized into several languages (so any changes made to the English version will have corresponding changes for other languages). I also want all of my markup to remain private (that is, if it's stored online somewhere, I should be the only person who can see my comments). I found an article that lists several website annotation services, but it's not clear whether they allow private annotations, or whether these tools are even appropriate for website maintenance (many of them look more geared toward social networking). I've started making a list of some necessary and desired features below, and may add more as necessary. Annotations/markup/comments remain private (only visible to me) Comment history/tagging (so I can reuse the same comment for shared footers, items requiring similar updates, etc.) Ability to print/export a list or report of all comments for the entire website Ability to produce a categorized list of changes (e.g., to produce a list of images that need updating, which I can send to the graphic designer) What processes and tools do you use to keep track of all the changes that need to be made to a website? What features are painfully absent from the tools you use?
