• Cisco VPN Client dropping connection

  - by IT Team

  Using Windows XP and Cisco VPN client version 5.0.4.xxx to connect to a remote customer site. We are able to establish the connection and start an RDP session, but within 1-2 minutes the connection drops and the VPN connection disconnects. The PC making the connection is on a DMZ which is NATed to a public IP address. If we move the PC directly onto the internet without being on the DMZ the connection works and we don't encounter any disconnects. We use a PIX 515E running 7.2.4 and don't have any problems with similar setups connecting to other customer sites from the DMZ. The VPN setup on the client side is pretty basic, using IPSec over TCP port 10000. Not sure what device they are using on the peer, but my guess would be an ASA. Any idea as to what the problem would be? Below is the logs from the VPN client when the problem occurs. The real IP address has been changed to: RemotePeerIP. 4 14:39:30.593 09/23/09 Sev=Info/4 CM/0x63100024 Attempt connection with server "RemotePeerIP" 5 14:39:30.593 09/23/09 Sev=Info/6 CM/0x6310002F Allocated local TCP port 1942 for TCP connection. 6 14:39:30.796 09/23/09 Sev=Info/4 IPSEC/0x63700008 IPSec driver successfully started 7 14:39:30.796 09/23/09 Sev=Info/4 IPSEC/0x63700014 Deleted all keys 8 14:39:30.796 09/23/09 Sev=Info/6 IPSEC/0x6370002C Sent 256 packets, 0 were fragmented. 9 14:39:30.796 09/23/09 Sev=Info/6 IPSEC/0x63700020 TCP SYN sent to RemotePeerIP, src port 1942, dst port 10000 10 14:39:30.796 09/23/09 Sev=Info/6 IPSEC/0x6370001C TCP SYN-ACK received from RemotePeerIP, src port 10000, dst port 1942 11 14:39:30.796 09/23/09 Sev=Info/6 IPSEC/0x63700021 TCP ACK sent to RemotePeerIP, src port 1942, dst port 10000 12 14:39:30.796 09/23/09 Sev=Warning/3 IPSEC/0xA370001C Bad cTCP trailer, Rsvd 26984, Magic# 63697672h, trailer len 101, MajorVer 13, MinorVer 10 13 14:39:30.796 09/23/09 Sev=Info/4 CM/0x63100029 TCP connection established on port 10000 with server "RemotePeerIP" 14 14:39:31.296 09/23/09 Sev=Info/4 CM/0x63100024 Attempt connection with server "RemotePeerIP" 15 14:39:31.296 09/23/09 Sev=Info/6 IKE/0x6300003B Attempting to establish a connection with RemotePeerIP. 16 14:39:31.296 09/23/09 Sev=Info/4 IKE/0x63000013 SENDING ISAKMP OAK AG (SA, KE, NON, ID, VID(Xauth), VID(dpd), VID(Frag), VID(Unity)) to RemotePeerIP 17 14:39:36.296 09/23/09 Sev=Info/4 IKE/0x63000021 Retransmitting last packet! 18 14:39:36.296 09/23/09 Sev=Info/4 IKE/0x63000013 SENDING ISAKMP OAK AG (Retransmission) to RemotePeerIP 19 14:39:41.296 09/23/09 Sev=Info/4 IKE/0x63000021 Retransmitting last packet! 20 14:39:41.296 09/23/09 Sev=Info/4 IKE/0x63000013 SENDING ISAKMP OAK AG (Retransmission) to RemotePeerIP 21 14:39:46.296 09/23/09 Sev=Info/4 IKE/0x63000021 Retransmitting last packet! 22 14:39:46.296 09/23/09 Sev=Info/4 IKE/0x63000013 SENDING ISAKMP OAK AG (Retransmission) to RemotePeerIP 23 14:39:51.328 09/23/09 Sev=Info/4 IKE/0x63000017 Marking IKE SA for deletion (I_Cookie=AEFC3FFF0405BBD6 R_Cookie=0000000000000000) reason = DEL_REASON_PEER_NOT_RESPONDING 24 14:39:51.828 09/23/09 Sev=Info/4 IKE/0x6300004B Discarding IKE SA negotiation (I_Cookie=AEFC3FFF0405BBD6 R_Cookie=0000000000000000) reason = DEL_REASON_PEER_NOT_RESPONDING 25 14:39:51.828 09/23/09 Sev=Info/4 CM/0x63100014 Unable to establish Phase 1 SA with server "RemotePeerIP" because of "DEL_REASON_PEER_NOT_RESPONDING" 26 14:39:51.828 09/23/09 Sev=Info/5 CM/0x63100025 Initializing CVPNDrv 27 14:39:51.828 09/23/09 Sev=Info/4 CM/0x6310002D Resetting TCP connection on port 10000 28 14:39:51.828 09/23/09 Sev=Info/6 CM/0x63100030 Removed local TCP port 1942 for TCP connection. 29 14:39:51.828 09/23/09 Sev=Info/6 CM/0x63100046 Set tunnel established flag in registry to 0. 30 14:39:51.828 09/23/09 Sev=Info/4 IKE/0x63000001 IKE received signal to terminate VPN connection 31 14:39:52.328 09/23/09 Sev=Info/6 IPSEC/0x63700023 TCP RST sent to RemotePeerIP, src port 1942, dst port 10000 32 14:39:52.328 09/23/09 Sev=Info/4 IPSEC/0x63700014 Deleted all keys 33 14:39:52.328 09/23/09 Sev=Info/4 IPSEC/0x63700014 Deleted all keys 34 14:39:52.328 09/23/09 Sev=Info/4 IPSEC/0x63700014 Deleted all keys 35 14:39:52.328 09/23/09 Sev=Info/4 IPSEC/0x6370000A IPSec driver successfully stopped Thank you for any help you can provide.

• IIS7 web farm - local or shared content?

  - by rbeier

  We're setting up an IIS7 web farm with two servers. Should each server have its own local copy of the content, or should they pull content directly from a UNC share? What are the pros and cons of each approach? We currently have a single live server WEB1, with content stored locally on a separate partition. A job periodically syncs WEB1 to a standby server WEB2, using robocopy for content and msdeploy for config. If WEB1 goes down, Nagios notifies us, and we manually run a script to move the IP addresses to WEB2's network interface. Both servers are actually VMs running on separate VMWare ESX 4 hosts. The servers are domain-joined. We have around 50-60 live sites on WEB1 - mostly ASP.NET, with a few that are just static HTML. Most are low-traffic "microsites". A few have moderate traffic, but none are massive. We'd like to change this so both WEB1 and WEB2 are actively serving content. This is mainly for reliability - if WEB1 goes down, we don't want to have to manually intervene to fail things over. Spreading the load is also nice, but the load is not high enough right now for us to need this. We're planning to configure our firewall to balance traffic across the two servers. It will detect when a server goes down and will send all the traffic to the remaining live server. We're planning to use sticky sessions for now... eventually we may move to SQL Server session state and stateless load balancing. But we need a way for the servers to share content. We were originally planning to move all the content to a UNC share. Our storage provider says they can set up a highly available SMB share for us. So if we go the UNC route, the storage shouldn't be a single point of failure. But we're wondering about the downsides to this approach: We'll need to change the physical paths for each site and virtual directory. There are also some projects that have absolute paths in their web.config files - we'll have to update those as well. We'll need to create a domain user for the web servers to access the share, and grant that user appropriate permissions. I haven't looked into this yet - I'm not sure if the application pool identity needs to be changed to this user, or if there's another way to tell IIS to use this account when connecting to the share. Sites will no longer be able to access their content if there's ever an Active Directory problem. In general, it just seems a lot more complicated, with more moving parts that could break. Our storage provider would create a volume for us on their redundant SAN. If I understand correctly, this SAN volume would be mounted on a VM running in their redundant VMWare environment; this VM would then expose the SMB share to our web servers. On the other hand, a benefit of the shared content approach is that we'd only need to deploy code to one place, and there would never be a temporary inconsistency between multiple copies of the content. This thread is pretty interesting, though some of these people are working at a much larger scale. I've just been discussing content so far, but we also need to think about configuration. I don't know if we can just use DFS replication for the applicationHost.config and other files, or if it's best to use the shared configuration feature with the config on a UNC share. What do you think? Thanks for your help, Richard

• Ubuntu: Failure to login with multiple video adapters

  - by tsilb

  Forgive my ignorance, for I am a complete linux noob. I have a computer with three video cards and six monitors. Works great on Windows. Trying to get it to run Ubuntu as well. It loads fine when I have it configured to run on one adapter; detects both screens, runs ok. But I want to turn the other 4 monitors on and run the whole thing as one extended desktop (one session, etc). So I downloaded and installed the newest ATI driver for Linux, which seems to work, kinda. I ran this to set up the screens: aticonfig --adapter=all --initial -f Now when I boot, Ubuntu seems to turn on all the screens (3 viewports, each with two cloned displays from what I can tell). When I enter my login info OR move the mouse off the main screen, the screens freeze and the kbd/ms become unresponsive. aticonfig generated xorg.conf included below. Have tried the following: aticonfig -initial -f - works, but only detects the primary adapter and 2 screens aticccle - Tells me I have to reboot after enabling the other cards. Then goes into above described freezing state. aticonfig --adapter=all --initial -f - see above Manually editing xorg.conf file with my limited knowledge - Was able to get two adapters running, but only the second adapter initialized while the primary stopped at the Ubuntu boot screen. Was unable to see the login prompt. Froze after I logged in blindly (was able to hear the login sound). Using generic "radeon" driver instead of ATI Proprietary driver with the above init attempts Toggling xinerama Various combinations of the above Hardware: Intel Core 2 Quad q6600 8GB DDR2 (3x) ATI Radeon HD 4680 5 monitors (21W, 21W, 22W Portrait, 22W Portrait, 19")and an HDTV (26"W, HDMI) in a horizontal arrangement I know next to nothing about Linux/Ubuntu aside from basic filesystem navigation, editing text files, and accessing my local and networked Windows stores and shares. Basically this is the most advanced thing I've had to do. I installed today.

• Windows 7 Samba issue

  - by abduls85

  We have a strange samba issue affecting only one user. Our samba setup is as follow : Red Hat Enterprise Linux Server release 5.4 (Tikanga) - Samba Server Samba version 3.0.33-3.14.el5 - Samba version Domain Controller WIN2008R2 Standard - Windows DC Windows 7 64 bit - Client PCs User mentioned that he faced this problem after he force shutdown his PC few weeks ago. By right, for all users when we access \\sambaservername in windows it will show all the shares in the samba server but for this user once he startup his PC he will not be able to access \\sambaservername, Error message Windows cannot access \\sambaservername Current workaround to solve the problem : Try to access one share in \\sambaservername for instance \\sambaservername\sharedfolder1. But even when doing so, it will first prompt an error in the beginning, error message is as follows Logon failure: unknown user name or bad password. user need to enter the credentials again and he can access the share. Thereafter, he will be able to access \\sambaservername without any issues. But once he reboots his computer the problem will persists. Troubleshooting done so far: Ensure the following settings: Go to: Control Panel → Administrative Tools → Local Security Policy Select: Local Policies → Security Options "Network security: LAN Manager authentication level" → Send LM & NTLM responses "Minimum session security for NTLM SSP" → uncheck: Require 128-bit encryption Advise user to reset his password and try again but problem still persists Tried my account on users' PC, there is no issues. Tried user account on serveral other Windows 7 PC including mine but problem still persists. Windows XP does not have this problem. Ensure that there is no stored crendentials on the windows 7 PC. Checked the credentials manager in Control Panel as well as typing this command rundll32.exe keymgr.dll, KRShowKeyMgr Restart winbindd daemon on samba server but to no avail. I suspect this is due to some caching issue but not sure where is the issue. Whenever the user has error accessing \\sambaservername, the following errors will be logged in the samba server : [2012/10/10 17:10:26, 1] smbd/sesssetup.c:reply_spnego_kerberos(316) Failed to verify incoming ticket with error NT_STATUS_LOGON_FAILURE!

• creating a heirarchy of terminals or workspaces

  - by intuited

  <rant This question occurred to me ('occurred' meaning 'whispered seductively in my ear for the 100th time') while using GNU-screen, so I'll make that my example. However this is a much more general question about user interfaces and what I perceive as a flawmissing feature in every implementation I've yet seen. I'm wondering if there is some way to create a heirarchy/tree of terminals in a screen session. EG I'd like to have something like 1 bash 1.1 bash 1.2 bash 2 bash 3 bash 3.1 bash 3.1.1 bash 3.1.2 bash It would be good if the terminals could be labelled instead of having to be navigated to via some arrangement that I suspect doesn't exist. So then you could jump to one using eg ^A:goto happydays or ^A:goto dykstra.angry. So to generalize that: Firefox, Chrome, Internet Explorer, gnome-terminal, roxterm, konsole, yakuake, OpenOffice, Microsoft Office, Mr. Snuffaluppagus's Funtime Carousel™, and Your Mom's Jam Browser™ all offer the ability to create a flat set of tabs containing documents of an identical nature: web pages, terminals, documents, fun rideable animals, and jams. GNU-screen implements the same functionality without using tabs. Linux and OS/X window managers provide the ability to organize windows into an array of workspaces, which amounts to again, the same deal. Over the past few years, this has become a more or less ubiquitous concept which has been righteously welcomed into the far reaches of the computer interface funfest. Heavy users of these systems quickly encounter a problem with it: the set of entities is flat. In the case of workspaces, an option may be available to create a 2d array. However none of these applications furnish their users with the ability to create heirarchies, similar to filesystem directory structures, containing instances of their particular contained type. I for one am consistently bothered by this, and am wondering if the community can offer some wisdom as to why this has not happened in any of the foremost collections of computational functionality our culture has yet produced. Or if perhaps it has and I'm just an ignorant savage. I'd like to be able to not only group things into a tree structure, but also to create references (aka symbolic links, aka pointers) from one part of the structure to another, as well as apply properties (eg default directory, colorscheme, ...) recursively downward from a given node. I see no reason why we shouldn't be able to save these structures as known sessions, and apply tags to particular instances. So then you can sort through them by tag, find them by name, or just use the arrow keys (with an appropriate modifier) to move left or right and in or out of a given level. Another key combo would serve to create a branch in the place of the current terminal/webpage/lifelike statue/spreadsheet/spreadsheet sheet/presentation/jam and move that entity into the new branch, then create a fresh one as a sibling to it: a second leaf node within the same branch node. They would get along well. I find it a bit astonishing that this hasn't happened yet, and the only reason I can venture as a guess is that the creators of these fine systems do not consider such functionality to be useful to a significant portion of their userbase. I posit that the probability that that such an assumption would be correct is pretty low. On the other hand, given the relative ease with which such structures can be implemented using modern libraries/languages, it doesn't seem likely that difficulty of implementation would be a major roadblock. If it could be done in 1972 or whenever within the constraints of a filesystem driver, it should be relatively painless to implement in 2010 in a fullblown application. Given that all of these systems are capable of maintaining a set of equivalent entities, it seems unlikely that a major infrastructure overhaul would be necessary in order to enable a navigable heirarchy of them. </rant Mostly I'm just looking to start up a discussion and/or brainstorming on this topic. Any ideas, examples, criticism, or analysis are quite welcome. * Mr. Snuffaluppagus's Funtime Carousel is a registered trademark of Children's Television Workshop Inc. * Your Mom's Jam Browser is a registered trademark of Your Mom Inc.

• rdiff-backup is taking longer and longer every time it runs

  I've been running rdiff-backup for the past week or so, every night at 4am. It started out not taking that long, but its taking longer and longer and longer every time its runs every night. In some cases there are quite a few new and changed files and in other cases, not so much. It started out taking < 10 minutes, and after a week its taking over 4.5 hrs to run.

• Users loggin to 3Com switches authenticated by radius not getting admin priv and no access available

  - by 3D1L

  Hi, Following the setup that I have for my Cisco devices, I got some basic level of functionality authenticating users that loggin to 3Com switches authenticated against a RADIUS server. Problem is that I can not get the user to obtain admin privileges. I'm using Microsoft's IAS service. According to 3Com documentation when configuring the access policy on IAS the value of 010600000003 have to be used to specify admin access level. That value have to be input in the Dial-in profile section: 010600000003 - indicates admin privileges 010600000002 - manager 010600000001 - monitor 010600000000 - visitor Here is the configuration on the switch: radius scheme system server-type standard primary authentication XXX.XXX.XXX.XXX accounting optional key authentication XXXXXX key accounting XXXXXX domain system scheme radius-scheme system local-user admin service-type ssh telnet terminal level 3 local-user manager service-type ssh telnet terminal level 2 local-user monitor service-type ssh telnet terminal level 1 The configuration is working with the IAS server because I can check user login events with the Eventviewer tool.

• Is the Cloud ready for an Enterprise Java web application? Seeking a JEE hosting advice.

  - by Jakub Holý

  Greetings to all the smart people around here! I'd like to ask whether it is feasible or a good idea at all to deploy a Java enterprise web application to a Cloud such as Amazon EC2. More exactly, I'm looking for infrastructure options for an application that shall handle few hundred users with long but neither CPU nor memory intensive sessions. I'm considering dedicated servers, virtual private servers (VPSs) and EC2. I've noticed that there is a project called JBoss Cloud so people are working on enabling such a deployment, on the other hand it doesn't seem to be mature yet and I'm not sure that the cloud is ready for this kind of applications, which differs from the typical cloud-based applications like Twitter. Would you recommend to deploy it to the cloud? What are the pros and cons? The application is a Java EE 5 web application whose main function is to enable users to compose their own customized Product by combining the available Parts. It uses stateless and stateful session beans and JPA for persistence of entities to a RDBMS and fetches information about Parts from the company's inventory system via a web service. Aside of external users it's used also by few internal ones, who are authenticated against the company's LDAP. The application should handle around 300-400 concurrent users building their product and should be reasonably scalable and available though these qualities are only of a medium importance at this stage. I've proposed an architecture consisting of a firewall (FW) and load balancer supporting sticky sessions and https (in the Cloud this would be replaced with EC2's Elastic Load Balancing service and FW on the app. servers, in a physical architecture the load-balancer would be a HW), then two physical clustered application servers combined with web servers (so that if one fails, a user doesn't loose his/her long built product) and finally a database server. The DB server would need a slave backup instance that can replace the master instance if it fails. This should provide reasonable availability and fault tolerance and provide good scalability as long as a single RDBMS can keep with the load, which should be OK for quite a while because most of the operations are done in the memory using a stateful bean and only occasionally stored or retrieved from the DB and the amount of data is low too. A problematic part could be the dependency on the remote inventory system webservice but with good caching of its outputs in the application it should be OK too. Unfortunately I've only vague idea of the system resources (memory size, number and speed of CPUs/cores) that such an "average Java EE application" for few hundred users needs. My rough and mostly unfounded estimate based on actual Amazon offerings is that 1.7GB and a single, 2-core "modern CPU" with speed around 2.5GHz (the High-CPU Medium Instance) should be sufficient for any of the two application servers (since we can handle higher load by provisioning more of them). Alternatively I would consider using the Large instance (64b, 7.5GB RAM, 2 cores at 1GHz) So my question is whether such a deployment to the cloud is technically and financially feasible or whether dedicated/VPS servers would be a better option and whether there are some real-world experiences with something similar. Thank you very much! /Jakub Holy PS: I've found the JBoss EAP in a Cloud Case Study that shows that it is possible to deploy a real-world Java EE application to the EC2 cloud but unfortunately there're no details regarding topology, instance types, or anything :-(

• Deploying play! 2.0 application on an apache server with a reverse proxy

  - by locrizak

  I'm trying to deploy my play! 2.0 application on an Ubuntu 11.10 server and I have been running into error after error and hope someone can help me here. I am try to deploy my Play! application using a reverse proxy on Apache 2. I have enabled the apache proxy modules and configured the proxy.conf file in mods_enabled. The vhost for my domain looks like this: <Directory /var/www/stage.domain.com AllowOverride None Order Deny,Allow Deny from all </Directory <VirtualHost *:80 DocumentRoot /var/www/stage.domain.com/web ServerName stage.domain.com ServerAdmin [email protected] # ProxyRequests Off # ProxyPreserveHost On <Proxy * Order allow,deny Allow from all </Proxy # ProxyVia On # ProxyPass /play/ http://localhost:9000/ # ProxyPassReverse /play/ http://localhost:9000/ ErrorLog /var/log/ispconfig/httpd/stage.domain.com/error.log ErrorDocument 400 /error/400.html ErrorDocument 401 /error/401.html ErrorDocument 403 /error/403.html ErrorDocument 404 /error/404.html ErrorDocument 405 /error/405.html ErrorDocument 500 /error/500.html ErrorDocument 502 /error/502.html ErrorDocument 503 /error/503.html <IfModule mod_ssl.c </IfModule <Directory /var/www/stage.domain.com/web Options FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory <Directory /var/www/clients/client2/web7/web Options FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory # Clear PHP settings of this website <FilesMatch "\.ph(p3?|tml)$" SetHandler None </FilesMatch # mod_php enabled AddType application/x-httpd-php .php .php3 .php4 .php5 php_admin_value sendmail_path "/usr/sbin/sendmail -t -i [email protected]" php_admin_value upload_tmp_dir /var/www/clients/client2/web7/tmp php_admin_value session.save_path /var/www/clients/client2/web7/tmp # PHPIniDir /var/www/conf/web7 php_admin_value open_basedir /var/www/clients/client2/web7/:/var/www/clients/client2/web7/web:/va$ # add support for apache mpm_itk <IfModule mpm_itk_module AssignUserId web7 client2 </IfModule <IfModule mod_dav_fs.c # Do not execute PHP files in webdav directory <Directory /var/www/clients/client2/web7/webdav <FilesMatch "\.ph(p3?|tml)$" SetHandler None </FilesMatch </Directory # DO NOT REMOVE THE COMMENTS! # IF YOU REMOVE THEM, WEBDAV WILL NOT WORK ANYMORE! # WEBDAV BEGIN # WEBDAV END </IfModule # <Location /play/ # ProxyPass http://localhost:9000/ # SetEnv force-proxy-request-1.0 1 # SetEnv proxy-nokeepalive 1 # </Location ProxyRequests Off ProxyPass /play/ http://localhost:9000/ ProxyPassReverse /play/ localhost:9000/ ProxyPass /play http://localhost:9000/ ProxyPassReverse /play http://localhost:9000/ # SetEnv force-proxy-request-1.0 1 # SetEnv proxy-nokeepalive 1 </VirtualHost This vhost file was generated by ispconfig and I have not touched anything that was there before just added onto. As you can see by the commented out parts I have tried a lot of different things based on random tutorials I have found but all of them have ended up in Internal Server Error, 503 and most often a '502 Bad Gateway`. I can start play and it does connect successfully to my database. I can get a page to show up when there is an error and the play! stack trace error pages comes up but where everything is fine I get one of the errors above. My application.conf file looks like this: db info ....... application.mode=PROD logger.root=ERROR # Logger used by the framework: logger.play=INFO # Logger provided to your application: logger.application=DEBUG http.path="/play/" XForwardedSupport="127.0.0.1" And my hosts file looks like this (I have never changed or added anything to the host file): 127.0.0.1 localhost 127.0.1.1 matrix # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters Any insights onto what I might be doing wrong or if theres anything I can try please let me know! Thanks!! Edit Again the reverse proxy will work (I checked with sending to to google.com). Its when there is a successful connection to Netty. It's like Netty refuses the connection to the page. Edit 2 output from apachectl -S _default_:8081 127.0.0.1 (/etc/apache2/sites-enabled/000-apps.vhost:10) *:8090 is a NameVirtualHost default server 127.0.0.1 (/etc/apache2/sites-enabled/000-ispconfig.vhost:10) port 8090 namevhost 127.0.0.1 (/etc/apache2/sites-enabled/000-ispconfig.vhost:10) *:80 is a NameVirtualHost default server 127.0.0.1 (/etc/apache2/sites-enabled/000-default:1) port 80 namevhost 127.0.0.1 (/etc/apache2/sites-enabled/000-default:1) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7) port 80 namevhost stage.domain.com (/etc/apache2/sites-enabled/100-stage.domain.com.vhost:7) port 80 namevhost domain.com (/etc/apache2/sites-enabled/100-domain.com.vhost:7)

• Samba4 [homes] share

  - by SambaDrivesMeCrazy

  I am having issues with the [homes] share. OS is Ubuntu 12.04. I've installed samba 4.0.3, bind9 dlz, ntp, winbind, everything but pam modules, and did all the tests from https://wiki.samba.org/index.php/Samba_AD_DC_HOWTO. Running getent passwd and getent user work just fine. Creating a simple share works just fine too. I can manage the users, GPOs, and DNS from the windows mmc snap-ins. I can join winxp,7,8 to the domain and log on perfectly. I can change my passwords from windows, etc..etc.. I could say that everything is fine and be happy :) buuuut, no, home directories do not work. Searching in here, and on our good friend google I gathered that a simple [homes] read only = no path = /storage-server/users/ and mapping the user's home folder in dsa.msc to \\server-001\username or \\server-001\homes should get me a home share I could map for my user homedir. But the snap-in give me an error saying that it cannot create the home folder because the network name has not been found (rough translation from portuguese). also, running root@server-001:/storage-server/users# smbclient //server-001/test -Utest%'12345678' -c 'ls' Domain=[MYDOMAIN] OS=[Unix] Server=[Samba 4.0.3] tree connect failed: NT_STATUS_BAD_NETWORK_NAME Server name is alright, if I go for a simple share on the same server it opens just fine. If I map the user homedir to this simple share it works. What I want is that I dont have to go and manually make a new folder on linux everytime I create a new user on windows. It looks like permissions but I cant find any documentation on this (yes I've tried the manpages, but its hard to tell with so many options on man smb.conf alone). My smb.conf right now looks like this (pretty simple I know) # Global parameters [global] workgroup = MYDOMAIN realm = MYDOMAIN.LAN netbios name = SERVER-001 server role = active directory domain controller server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbind, ntp_signd, kcc, dnsupdate [netlogon] path = /usr/local/samba/var/locks/sysvol/mydomain.lan/scripts read only = No [sysvol] path = /usr/local/samba/var/locks/sysvol read only = No [homes] read only = no path = /storage-server/users Folder permissions /storage-server drwxr-xr-x 6 root root 4096 Fev 15 15:17 storage-server /storage-server/users drwxrwxrwx 6 root root 4096 Fev 18 17:05 users/ Yes, I was desperate enough to set 777 on the users folder... not proud of it. Any pointers in the right direction would be very welcome. Edited to include: root@server-001:/# wbinfo --user-info=test MYDOMAIN\test:*:3000045:100:test:/home/MYDOMAIN/test:/bin/false root@server-001:/# wbinfo -n test S-1-5-21-1957592451-3401938807-633234758-1128 SID_USER (1) root@server-001:/# id test uid=3000045(MYDOMAIN\test) gid=100(users) grupos=100(users) root@server-001:/# wbinfo -U 3000045 S-1-5-21-1957592451-3401938807-633234758-1128 root@server-001:/# Edit 2: getent passwd | grep test MYDOMAIN\test:*:3000045:100:test:/home/MYDOMAIN/test:/bin/false I have no idea how to change that home folder to /storage-server/users/test so I just went and ln -s /storage-server/users /home/MYDOMAIN just in case. still, no changes, same errors. Edit 3 On log.smbd I get the following error when trying to set the test user home folder to \server-001\test [2013/02/20 14:22:08.446658, 2] ../source3/smbd/service.c:418(create_connection_session_info) user 'MYDOMAIN\Administrator' (from session setup) not permitted to access this share (test)

• after enabling mod ssl apache stops listening on port 80

  I have an ubuntu 12.04 server with zend server CE installed.

• Strange Upload Problem on Hyper-V

  - by Ring0

  Hi, This one is driving me totally nuts. I have being trying to upload a file to www.virustotal.com (its a harmless exe I have since found out - DiskWipe.exe from diskwipe.org). Using IE8. From Win 7 and Win 2008 R2 Datacenter (which I select to boot from vhd's) onto my main machine hardware, and also on another Win 7 PC elsewhere on my network, when I upload the file to virustotal.com it works perfectly. So, using my native NIC's everything is fine. Using another machine also perfect. Right. OK, from my boot menu the default is my main development machine - the one I'm typing on now. This runs on the metal and has Hyper-V role and I have some guests. All guests are not running. Amazingly, from my console (root partition to be exact) or any guest OS 2003 /XP / 2008 R2 etc. My upload to virustotal.com slows at 32% then HANGS at 38.something% & never finishes!! Here is the kicker. I have another box (my main server) running Hyper-V on the metal and three live guests. Identical H/W to my main dev machine in another room. (Except OS is Datacenter - Mine is Enterprise). If I try and upload from its bare metal console or any guest this file to virustotal.com using IE8 it stops exactly in the same place!! As for "steps I have tried etc." are kind-of blown out of the water as my server box is doing the precise same thing as the machine in my room here. OK, comonalities: Mobo: Gigabyte GA-X58-UD5, 12GB Kingston RAM, Corei7 920 4 cores hyperthreading = 8 & Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet NIC's. All 3 machines have this same motherboard - revision F11 Bios, all have 12GB RAM, all have the Realtek Nic's. All x64 by the way as I mentioned before I have a Win 7 box also with the UD5 m/Board, 12 GB RAM - bit of an overkill. :-) All these machines when NOT running Hyper-V can upload this file. Perhaps you may like to try it on a Hyepr-v (2008 R2) yourselves with IE8 and the desktop experience is on. See if it works or fails for you. Root OS or any guest. So, looking like its the NIC + Hyper-V = Cannot upload this file (any file I must add.) Realtek Nic is Ver 7.002.1125.2008. Using IE8 I see in the nic settings there are the usual parameters for Jumbo frames / Checksum offloading etc. several others. Should I fiddle with these? I ran Netmon 3.3 in a guest and the TCP session halted as the upload failed. I suppose I could study that further. I dont have Netmon on the root partition machine (yet)! All OS's fully patched - including todays defender files. My box running Office 2007 - but identical server in another room is not. Also, if I fire up a VPN to a distant client and do the upload it works! Of course its a different network path. Suggestions welcome please. If I left out anything important - please yell at me. Many Thanks,

• segfault when cd-ing into certain directories in bash

  - by user84207

  I have noticed this very strange behavior recently.

• Site-to-site VPN using MD5 instead of SHA and getting regular disconnection

  - by Steven

  We are experiencing some strange behavior with a site-to-site IPsec VPN that goes down about every week for 30 minutes (Iam told 30 minutes exactly). I don't have access to the logs, so it's difficult to troubleshoot. What is also strange is that the two VPN devices are set to use SHA hash algorithm but apparently end up agreeing to use MD5. Does anybody have a clue? or is this just insufficient information? Edit: Here is an extract of the log of one of the two VPN devices, which is a Cisco 3000 series VPN concentrator. 27981 03/08/2010 10:02:16.290 SEV=4 IKE/41 RPT=16120 xxxxxxxx IKE Initiator: New Phase 1, Intf 2, IKE Peer xxxxxxxx local Proxy Address xxxxxxxx, remote Proxy Address xxxxxxxx, SA (L2L: 1A) 27983 03/08/2010 10:02:56.930 SEV=4 IKE/41 RPT=16121 xxxxxxxx IKE Initiator: New Phase 1, Intf 2, IKE Peer xxxxxxxx local Proxy Address xxxxxxxx, remote Proxy Address xxxxxxxx, SA (L2L: 1A) 27986 03/08/2010 10:03:35.370 SEV=4 IKE/41 RPT=16122 xxxxxxxx IKE Initiator: New Phase 1, Intf 2, IKE Peer xxxxxxxx local Proxy Address xxxxxxxx, remote Proxy Address xxxxxxxx, SA (L2L: 1A) [… same continues for another 15 minutes …] 28093 03/08/2010 10:19:46.710 SEV=4 IKE/41 RPT=16140 xxxxxxxx IKE Initiator: New Phase 1, Intf 2, IKE Peer xxxxxxxx local Proxy Address xxxxxxxx, remote Proxy Address xxxxxxxx, SA (L2L: 1A) 28096 03/08/2010 10:20:17.720 SEV=5 IKE/172 RPT=1291 xxxxxxxx Group [xxxxxxxx] Automatic NAT Detection Status: Remote end is NOT behind a NAT device This end IS behind a NAT device 28100 03/08/2010 10:20:17.820 SEV=3 IKE/134 RPT=79 xxxxxxxx Group [xxxxxxxx] Mismatch: Configured LAN-to-LAN proposal differs from negotiated proposal.

• Call to daemon in a /etc/init.d script is blocking, not running in background

  - by tony

  I have a Perl script that I want to daemonize. Basically this perl script will read a directory every 30 seconds, read the files that it finds and then process the data. To keep it simple here consider the following Perl script (called synpipe_server, there is a symbolic link of this script in /usr/sbin/) : #!/usr/bin/perl use strict; use warnings; my $continue = 1; $SIG{'TERM'} = sub { $continue = 0; print "Caught TERM signal\n"; }; $SIG{'INT'} = sub { $continue = 0; print "Caught INT signal\n"; }; my $i = 0; while ($continue) { #do stuff print "Hello, I am running " . ++$i . "\n"; sleep 3; } So this script basically prints something every 3 seconds. Then, as I want to daemonize this script, I've also put this bash script (also called synpipe_server) in /etc/init.d/ : #!/bin/bash # synpipe_server : This starts and stops synpipe_server # # chkconfig: 12345 12 88 # description: Monitors all production pipelines # processname: synpipe_server # pidfile: /var/run/synpipe_server.pid # Source function library. . /etc/rc.d/init.d/functions pname="synpipe_server" exe="/usr/sbin/synpipe_server" pidfile="/var/run/${pname}.pid" lockfile="/var/lock/subsys/${pname}" [ -x $exe ] || exit 0 RETVAL=0 start() { echo -n "Starting $pname : " daemon ${exe} RETVAL=$? PID=$! echo [ $RETVAL -eq 0 ] && touch ${lockfile} echo $PID > ${pidfile} } stop() { echo -n "Shutting down $pname : " killproc ${exe} RETVAL=$? echo if [ $RETVAL -eq 0 ]; then rm -f ${lockfile} rm -f ${pidfile} fi } restart() { echo -n "Restarting $pname : " stop sleep 2 start } case "$1" in start) start ;; stop) stop ;; status) status ${pname} ;; restart) restart ;; *) echo "Usage: $0 {start|stop|status|restart}" ;; esac exit 0 So, (if I have well understood the doc for daemon) the Perl script should run in the background and the output should be redirected to /dev/null if I execute : service synpipe_server start But here is what I get instead : [root@master init.d]# service synpipe_server start Starting synpipe_server : Hello, I am running 1 Hello, I am running 2 Hello, I am running 3 Hello, I am running 4 Caught INT signal [ OK ] [root@master init.d]# So it starts the Perl script but runs it without detaching it from the current terminal session, and I can see the output printed in my console ... which is not really what I was expecting. Moreover, the PID file is empty (or with a line feed only, no pid returned by daemon). Does anyone have any idea of what I am doing wrong ? EDIT : maybe I should say that I am on a Red Hat machine. Scientific Linux SL release 5.4 (Boron) Would it do the job if instead of using the daemon function, I use something like : nohup ${exe} >/dev/null 2>&1 & in the init script ?

• Windows 7 sometimes boots in VGA mode

  - by TuxRug

  I have an Asus G50VT-x5 laptop with nVidia GeForce9800M-GS graphics. Normally, Windows boots normally, but about 20% of the time (rough estimate), it will boot with the fallback VGA driver, maxing out at 800x600 with no Aero. I've checked the system logs and there is nothing indicating an error loading the nVidia driver. It even specifies in the logs that the Nvidia Display Driver service started successfully, even though it has booted in safe graphics mode. This has been happening for a while, but it's happening a little more often now than it was before. Since the first time my system exhibited this behavior, I have updated my graphics driver a handful of times. I used System Information for Windows to check for problems there, but the only thing that stood out was the following: Core Temperature 4486449 °C (8075639 °F) Shaders Temperature 1171513530 °C (2108724330 °F) I know this reading is incorrect, because my laptop is nowhere near the surface of the sun and my desk has not burst into flames. When it's opererating normally, I get a sane reading like [Core Temperature 58 °C (136 °F)] with no Shaders Temperature listed. All I have to do to resolve the issue is reboot. I have seen no stability issues with the graphics or anything else. A long time ago, I had an issue with this computer where my framerate would suddenly drop during a 3D game from 40fps to <1fps, but after looking at the temperature readout immediately after quitting a game, I removed the bottom panel and blew the dust out of the vent and heatsink. Since then I have no drops in framerate under any situation. I have uploaded a zip containing the SIW reports for when the problem is occurring and when the computer is operating normally. I don't have a paid account so it can only be downloaded 10 times, so please only download the reports if you think you can use them. If you try to download the reports and they are no longer available, please comment and I will re-upload them. If you want to look at the files, they are on Rapidshare. EDIT It happened again, and I looked a little deeper into the System logs. When this happens, there are a lot of errors about other device drivers unable to start. All of these errors are for PnP drivers. Also, my USB keyboard and mouse take a few moments before they actually start working, although this happens sometimes the first normal boot as well. I am quite sure this is related, so I am adding the pnp tag. Also, CHKDSK will not run on boot. Even if a check is scheduled or a volume is manually set as dirty, CHKDSK will be skipped entirely, not even leaving an entry in the System logs. I tried running CHKNTFS /D, which did not work. I then manually changed my HKLM\System\CurrentControlSet\Control\Session Manager BootExecute value to the default listed on Microsoft's website. That did not work either. I ended up booting to repair mode and running CHKDSK there, which found a number of minor inconsistencies on my system drive, but none on my data drive. I have no idea if this is related. Some more information for those who don't download my SIW report file: Antivirus and Firewall are ESET Smart Security I have three different virutalization programs installed: VMware Player, Windows Virtual PC, and VirtualBox. The network adapters for these show up in the log of failed device starts. EDIT 2 I tried running sfc /scannow, which reported that it found corrupted files that could not be fixed. The CBS log is extremely cryptic. I tried booting to my install disk, launching repair mode, and doing an offline sfc from there, which produced the same result.

• IMAPSync Migration to Exchange 2010 SP1: Exchange drops connections while checking for existence of folders

  - by Benjamin Priestman

  I'm migrating from ZImbra Collaboration Suite to Exchange 2010 SP1. I'm testing IMAPSync as a possible migration tool and have hit a problem with the IMAP server in Exchange 2010. For each account it migrates, IMAPSync loops through the list of folders in the source mailbox and tests for the existence of each one in the destination mailbox. It then goes on to create those folders that do not exist and copy over the messages. It's the intial testing for the existence of the folders that is giving me a problem. The response given by the Exchange server when the folder does not yet exist is given as an error: "R=""16 NO IMAPSyncTest/8 doesn't exist."" After ten of these errors have been issued in succession, the Exchange server appears to stop responding to the IMAP session. Enabling protocol logging for IMAP confirms that the 10th request for a non-existant folder is the last request to be logged on the server. IMAPSync carries on merrily without seeming to realise its connection has gone and thus fails to create any folders. I've logged this with the tool's creator. Does anyone have any idea why Exchange is stopping responding to the connections though? The behaviour looks rather like throttling, although the 'ten strikes and you're out' trigger does not seem to correspond to any of the triggers on the ThrottlingPolicies. Just to check, I've tried creating a new ThrottlingPolicy, turned everything that I think might be relevant up to 11 and applied it to the my test mailbox. Policy settings are listed below, along with IMAP settings. Everything else should be pretty much as default.

• Intermittent lockups, unable to diagnose in over a year

  - by Magsol

  Here's a real doosie; I may just give my firstborn child to whomever helps me solve this problem. In July 2008, I assembled what would be my desktop computer for graduate school. Here are the specs of the machine I built: Thermaltake 750W PSU Corsair Dominator 2x2GB 240-pin SDRAM Thermaltake Tower Asus P5K Deluxe Motherboard Intel Core 2 Quad Q9300 2.5GHz CPU 2 x GeForce 8600 GT WD Caviar Blue 640GB hard drive CD burner DVD burner Soon thereafter, I ordered a new motherboard (because I was an idiot; that first motherboard supported CrossFire, not SLI), an Asus P5N-D. I was originally running Windows XP SP3. Pretty much right into the start of the fall semester, my desktop would simply lock up after awhile. If my system was largely idling, it would be after 1-3 days. If was gaming, it often happened an hour or two into my gaming session, indicating a link to activity level. Here's where it started getting interesting. I started looking at the system temps. The CPU was warmer than it should have been (~60s C), so I purchased some more efficient cooling compound a way better cooler for it. Now it hardly goes over 40 C. Intel was even kind enough to swap it out for free, just to rule it out. Lockups continued. The graphics cards were also running pretty warm: about 60 C idling. Removing one of them seemed to improve stability a little bit...as in, it wouldn't lock up quite as frequently, but still always eventually locked up. But it didn't matter which card I used or removed, the lockups continued. I reverted back to the original motherboard, the P5K Deluxe. Lockups continued. I purchased an entirely new motherboard, eVGA's nForce 750i. Lockups continued. Ran memtest86+ over and over and over, with no errors. Even RMA'd the memory. Lockups continued. Replaced the PSU with a Corsair 750W PSU. Lockups continued. Tried disconnecting all IDE drives (HDDs are SATA). Lockups continued. Replaced both graphics cards with a single Radeon HD 4980. Average temps are now always around 50 C when idling, 60 C only when gaming. Lockups continued. Throughout the whole ordeal, the system has been upgraded from Windows XP SP3 to Vista 32-bit, to Vista 64-bit, and is now at Windows 7 64-bit. Lockups have occurred at every step along the way (each OS was in place for at least a few months before the next upgrade). Edit: By "upgrade" I mean clean install each time. In addition to those reformats, I have performed many, many other reformats of the system and a reinstall of whatever OS had been previously installed in an attempt to rectify this problem, to no avail./Edit When the system locks up, there's no blue screen, no reboot, no error message of any kind. It simply freezes in place until I hit the reset button. Very, very rarely, once Windows boots back up, the system informs me that Windows has recovered from an error, but it can never find the source aside from some piece of hardware. I've swapped out every component in this computer, and there are more fans in it than I care to count...though for the sake of completeness: top 80mm case fan (out) rear 80mm case fan (out) rear 120mm case fan (out) front 120mm case fan (in) side 250mm case fan (in) giant CPU fan on-board motherboard fan (the eVGA board) triple-fan memory setup (came with the memory) PSU internal fan another 120mm fan I stuck on the underside of the video card to keep hot air from collecting at the bottom of the case I'm truly out of ideas. ANY help at all would be oh-so-very GREATLY appreciated. Thank you!

• SQL2008R2 install issues on windows 7 - unable to install setup support files?

  - by Liam

  I am trying to install the above but am getting the following errors when its attempting to install the setup support files, This is the first error that occurs during installation of the setup support files TITLE: Microsoft SQL Server 2008 R2 Setup ------------------------------ The following error has occurred: The installer has encountered an unexpected error. The error code is 2337. Could not close file: Microsoft.SqlServer.GridControl.dll GetLastError: 0. Click 'Retry' to retry the failed action, or click 'Cancel' to cancel this action and continue setup. For help, click: http://go.microsoft.com/fwlink?LinkID=20476&ProdName=Microsoft+SQL+Server&EvtSrc=setup.rll&EvtID=50000&ProdVer=10.50.1600.1&EvtType=0xDF039760%25401201%25401 This is the second error that occurs after clicking continue in the installer after the first error is generated TITLE: Microsoft SQL Server 2008 R2 Setup ------------------------------ The following error has occurred: SQL Server Setup has encountered an error when running a Windows Installer file. Windows Installer error message: The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance. Windows Installer file: C:\Users\watto_uk\Desktop\In-Digital\Software\Microsoft\SQL Server 2008 R2\1033_ENU_LP\x64\setup\sqlsupport_msi\SqlSupport.msi Windows Installer log file: C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Log\20110713_205508\SqlSupport_Cpu64_1_ComponentUpdate.log Click 'Retry' to retry the failed action, or click 'Cancel' to cancel this action and continue setup.

I have also tried using the web platform installer to install the express version instead but the SQL Server Installation fails with that also. The management studio installs fine but not the server. I have checked to make sure that the Windows Installer is started and it is. Cant seem to find an answer for this anywhere as all previous reported issues appear to be related to XP. I did have the express edition installed on the machine previously but uninstalled it to upgrade to the full version, I wish I hadn't now. Can anyone kindly offer any advice or point me in the right direction to stop me going insane with this? Any advice will be appreciated. Update======================= After digging a bit deeper ive located details of the error from the setup log file, i can also upload the log file if required.
