• VMWare web UI intermittent access on CentOS

  - by PeteWilliams

  Hiya, I've got a CentOS 5.2 server that I'm trying to get set up as a development environment. As part of this, I planned to install VMWare Server 2 and set up several virtual development servers. I've got as far as installing VMWare Server 2 but access to the remote control panel is only working intermittently. If I access it through Firefox at https://127.0.0.1:8333/ui/# it usually says either: "Connection intterupted: connection was reset before the page loaded" Or "Firefox can't establish a connection to the server at 127.0.0.1" But every now and then it lets me in and I'll manage a few clicks in the web UI before it kicks me out with the following error: "The server could not complete a request (HTTP 0 ). The server encountered an unexpected condition that prevented it from fulfilling the request. If this problem persists, please contact your system administrator." I've done all the updates available in CentOS except one OpenOffice one that is causing a conflict, and I re-ran wmware-config.pl after updating the kernel. Though I went with all the defaults as I don't really know what I'm doing! I've since rebooted and nothing changed. I've also tried accessing the control panel remotely from another machine in the network and the results are the same. Does anyone have any ideas what might be causing this and how I can resolve it? I'm afraid I'm a developer playing at sys-admin, so I may be missing something obvious! Many thanks Pete Update I have now reinstalled both the operating system and VMWare and I'm still getting the same issue. I wonder if it's a result of the settings I'm putting in on the config.pl script..?

• xen + debian network after upgrade squeeze to wheeze

  - by rush

  I've got a Debian + Xen server. After a system upgrade to the stable version the network doesn't come up after boot. Every time after reboot I need to bring it up manually. The network configuration was not changed during upgrade. Here is /etc/network/interfaces: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 11.22.33.44 netmask 255.255.255.0 gateway 11.22.33.1 nameserver 8.8.8.8 After boot ip r shows no route and eth0 has no ip address. Manually ip and route setup goes fine and network starts working.

• Restrict Computer or Users from Internet but allow access to intranet and Windows Update / ePO?

  - by MoSiAc

  So this may be impossible but I've been asked to try and find something about it. So far nothing I have found is possible. I need to restrict specific machines or user accounts from regular Internet access but let them have access to the intranet portion of our network. I do not have Active Directory control, nor does anyone at my local workplace (corporate control in a different state). I have tried going through IPsec and doing this per local machine, but that system seems to have been removed from the images that are installed on these machines so that is out. So far the only other option I can think of is assigning the machines a specific ip address and removing their gateway access. This would probably work but the machines need to be able to receive updates that are being pushed to them through ePO and LanDesk. I would really like to do this on the user level because then if I need to do tech work to the machine and need internet access I can get to it but a "special" user could login and not be able to get into anything.

• Active Directory: how to be SURE users can change their own passwords?

  - by Latro

  Working on some project where a tool we have has to authenticate against AD connecting via LDAPS and perform password changes if required or requested. IN THEORY, the tool does that, and we have seen it work in other projects. IN PRACTICE, against this particular directory, it fails. Been driving me crazy. The particulars of the situation: Windows 2003 AD Defined a "technical user" for the LDAP connection with rights to change users passwords When password change is required - in this case, because pwdLastSet is 0 - the tool uses the technical account to go, bind to the controller and change the user password. If password change is not required but the user request it, then the bind is done with the user account. That last condition is the one that doesnt work. With the technical user the password change is possible, but with the user itself, it isnt. We get an error like this: LDAP access failed: javax.naming.directory.InvalidAttributeValueException: [LDAP: error code 19 - 0000052D: AtrErr: DSID-03190F00, #1: 0: 0000052D: DSID-03190F00, problem 1005 (CONSTRAINT_ATT_TYPE), data 0, Att 9005a (unicodePwd) no idea what DSID-03190F00 means cause it doesnt seem to be anywhere in google :-/ Been looking at several MS documentation pages and frankly, I'm not understanding one bit of it. There is some "control access right" called User-Change-Password that may, or may not, control what objects have the right to change their own password, which may, or may not, have to do with ACE and ACLs... There is GPO. There is maybe the password policy but it is only set to ask for passwords of 6 chars or more... Can anybody explain to me in easy-to-check steps how can I go and tell the AD admin guy (who is as lost as me) what to do to ensure that users in the AD directory (objectClass top,person,organizationalPerson and user) are able to change their own passwords by themselves? Thanks in advance

• SSD as primary or secondary drive on a small Linux server?

  - by Alex Martelli

  I'm pensioning off my 10-years-old home server and replacing it with an Ubuntu 10.04 box. The two storage devices are a Western Digital Caviar Green 2.0TB HD and an Intel X25-M 34nm Gen 2 80GB SATA II 2.5inch SSD (the box has 8GB RAM and an i5 750, if it matters). I don't care much about boot times (since I don't plan to reboot all that often;-); the main frequent, performance-demanding task will be (re)building large open source C or C++ software packages from sources (as an open source contributor, I do that often). So, I thought I'd keep the SSD as the secondary drive and the HD as the primary one, using the SSD mostly for the files that can otherwise demand a lot of seeking (esp. in a parallel make). However, the friendly vendor (perhaps more experienced in Windows systems than in Linux ones) thinks the "normal" way to configure the machine would be with the SSD as the primary drive. I'm pretty rusty on configuring and tuning systems, so, I thought I'd better double check on SuperUser... thanks in advance for advice about this choice!

• How to find the IP Address of a vm running on VMware (or other methods of using VM)

  - by sixtyfootersdude

  I am running VMware Workstation on a Linux box. When I power on a centOS (Linux) virtual machine I cannot get mouse or keyboard control of the machine. I suspect that it has something to do with the error message: You do not have VMware Tools installed in this guest. Chose "Install VMware Tools" from the VM menu. If I click on that menu option it inserts a virtual cd with drivers etc. This does not help me since I don't have keyboard or mouse control over the machine. I was thinking that if I could figure out the IP address or hostname I could use any number of protocols to get into the machine (SSH comes to mind). How can I get the IP address or hostname of this machine? Note: I did not create this machine. A coworker created it who is no longer with the company. Would save me a lot of time if I could get into the machine. I have login credentials so that won't be a problem.

• IIS FTP 7.5 Data Channel Problem (SSL)

  - by user59050

  Hey there I wonder if anyone can get me in the right direction. I am setting up both a FTPS Client and Server, FTPS Server using Microsoft’s iis FTP 7.5. On the client side it will be running on Linux and I am using M2crypto for the openssl wrapping (python). I am worried the problem is on the server side (iis7.5) due to the following discovery : If I host using Filezilla with BOTH the control and data channel being forced to be encrypted it works 100% (100% file transmission), if i use iis as the server everything works up to the point when the data channel takes over... i.e. all data of the retrieved file is already received correctly in my basket! The ftp server just won't send the final '226 Transfer complete.' on the cmd socket. Why? If i force the client or server to close the connection the file is 100% intact....If i use iis 7.5 with forced encryption on control channel all works 100% as long as i don’t force data channel... Here are some screenshots to demo this... Client View after Kill Client : pics @ http://forums.iis.net/p/1172936/1960994.aspx#1960994 Summary : We can establish the connection, do directory listings, start the upload, see the file (0bytes) created on the server but then the client hangs. If we terminate the client, the uploaded file on the server suddenly jumps up to full size.

• Problem with ubuntu 10.10 running from USB drive

  - by Surjya Narayana Padhi

  I recently downloaded Ubuntu 10.10 and created an USB drive with that. I started to run the Ubuntu from that USB drive. But I am facing so much problem. I am thinking why its not so much easy like Windows to do all my job in ubuntu. Always I get some error message or to install something. This time I am getting the following errors. I am trying to download and install Aircrack-ng. So used the command sudo apt-get install aircrack-ng. But the installation stops with the following error : update-initramfs: deferring update (trigger activated) cp: cannot stat `/vmlinuz': No such file or directory dpkg: error processing bcmwl-kernel-source (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: initramfs-tools bcmwl-kernel-source E: Sub-process /usr/bin/dpkg returned an error code (1) I don't even have the aptitude command installed till now. Are all these errors because of I am running the ubuntu from USB drive? Is there any simple and easy way to go to Ubuntu Software Center and download all the required essentials at one shot and then Aircrack-ng? I could not find the Aircrack-ng in Ubuntu Software Center Can anybody give me detail steps to solve all my problems above. I am frustrated searching for updates and installations. When something works and something does not work. Can anybody suggest me how I should proceed after installing ubuntu to run on a USB drive. So that I can use the OS like Windows. Like software download,wireless driver, sound, video, documents, C:, D: all things should be there. Please somebody help.

• Active Directory problems while trying to perfom compare operation

  I have CentOs 5.5 with Apache 2.2 and SVN installed. Also I have Windows 2003 R2 with Active Directory.

• Parking domains and avoiding so called "search engine penalities"

  - by senthilkumar-c

  I have purchased two domains from one particular registrar and hosting from GoDaddy. Assume they are domain1.com and domain2.com Assume my hosting IP address is 111.111.111.111 I added both domain1.com and domain2.com in my domain management control panel and gave the same two nameservers for both domains at my registrar's control panel. So, now, both domains should show the same website. When I ping "domain1.com" or "domain2.com" the results say - Pinging domain1.com [111.111.111.111] with 32 bytes of data: Pinging domain2.com [111.111.111.111] with 32 bytes of data: respectively. So, they both point to the same hosting IP. BUT, internally, I have configured IIS to point them to different folders so that different websites are shown. (My hosting plan is expensive and I intend to use the space and bandwidth for many websites). But still, technically, all domains point to same IP address. Is this a bad thing? Is this what is called "domain parking"? I read some search engine forum posts that two domains pointing to the same IP/Website will be penalised by search engines and stuff. I have also read that simply "parking" the domains won't attract penality. I don't know whether what I have done is parking or the so called "wrong" thing. Can someone shed light on what I have done and what I should do? I don't want to be blacklisted by any search engine. P.S. I know this is not a search engine forum, but I am new to website hosting and domains and I am very weak in nearly all technical terms and concepts relating to web hosting and domains. I thought this will be a good place to understand these things.

• Small maximum number of connections on a Linux router

  - by Eugene

  I have a Linux box acting as a router with no iptables or other firewall and no networking applications running on it, just pure router. I've put it in a test environment that generates many TCP connections, each having unique source and destination IP, and those connections go through this router. I'm observing that number of connections successfully created rise to approximately 500 and then no more connections can be created for several minutes, then another 100 connections can be created and there is another pause, and so on. If 10 connections for each source-destination pair are created, then maximum numbers go about 10 times up, so the problem is probably with many connections from different IPs. As traffic is simply routed, it doesn't have to do with number of file descriptors, iptables connection tracking and other things often proposed to check in similar cases. The box has plenty of free RAM and CPU, both NICs are gigabit. The kernel is 2.6.32. I've already tried increasing net.core.*mem_max, net.core.netdev_max_backlog and txqueuelen on both NICs, with completely no effect. What else should I check ? Is there some rate-limit in the kernel itself ?

• iptables: How to combine DNAT and SNAT to use a secondary IP address?

  - by Que_273

  There are lots of questions on here about iptables DNAT/SNAT setups but I haven't found one that solves my current problem. I have services bound to the IP address of eth0 (e.g. 192.168.0.20) and I also have a IP address on eth0:0 (192.168.0.40) which is shared with another server. Only one server is active, so this alias interface comes and goes depending on which server is active. In order to get traffic accepted by the service a DNAT rule is used to change the destination IP. iptables -t nat -A PREROUTING -d 192.168.0.40 -p udp --dport 7100 -j DNAT --to-destination 192.168.0.20 I also wish all outbound traffic from this service to appear to come from the shared IP, so that return responses will work in the event of a active-standby failover. iptables -t nat -A POSTROUTING -p udp --sport 7100 -j SNAT --to-source 192.168.0.40 My problem is that the SNAT rule is not always run. Inbound traffic causes a connection tracking entry like this. [root]# conntrack -L -p udp udp 17 170 src=192.168.0.185 dst=192.168.0.40 sport=7100 dport=7100 src=192.168.0.20 dst=192.168.0.185 sport=7100 dport=7100 [ASSURED] mark=0 secmark=0 use=2 which means the POSTROUTING chain is not run and outbound traffic leaves with the real IP address as the source. I am thinking I can set up a NOTRACK rule in the raw table to prevent conntracking for this port number, but is there a better or more efficient way to make this work? Edit - Alternative question: Is there a way (in CentOS/Linux) to have an interface that can be bound to but not used, such that it can be attached to the network or detached when a shared IP address is swapped between servers?

• How to get just value from database query in Excel?

  - by Corin

  I'm creating a spreadsheet as a collection point of information from a number of MS Access databases. I will run a query on each database to get a count of records in a particular table. Each database has the same structure but different content as they are used in different situations. So the query returns a single value, rec_count. I've figured out how to create that query, save it and then use it as the data source. So far so good. The problem is that Excel treats the query results as a table. So instead of getting just the single value the query returns, I also get the field name. Thus the result takes up two cells instead of one. When linking in the data source, I only see Table, PivotTable Report and PivotChart as options for viewing the data. I don't want any of those. I just want the single value without any formatting, column headers, etc. Is there a way to do this is Excel 2007?

• How to have LiveJournal delegate my OpenID to something else?

  - by T-Boy

  I understand that if I have full control over my domain, I can set it up so that I can delegate the task of authenticating to another OpenID service provider. The problem is, what I'd like to do is to get the LiveJournal server to pass the authentication to someone else, instead of having LJ doing it. Preferably what I'd like to do is get LiveJournal, when asked by a web site, say, "No, I don't do it anymore -- go to this address". The plan was that this address would then be in a domain I fully control, which then would pass it on to whichever service provider I choose. I don't even know if I've gotten my understanding of OpenID right, if all this shenanigans are necessary, if my question makes sense, or if it's even possible with a service provider like Livejournal. ETA: Doing a little more reading up, and examining the source for my LiveJournal user page, I note that this particular line in the file's <header> area: <link rel="openid.server" href="http://www.livejournal.com/openid/server.bml" /> I suspect that changing this will allow me to forward OpenID requests to whomever I wish, I think; so far so good. Now comes the hard part -- figuring out how to change all of that using LiveJournal's customization options, if that is at all possible (here's hoping I don't need to pay to get that functionality).

• Apache LDAP with local groups

  - by Greg Ogle

  I have a server that currently uses htpasswd to authenticate users. I'm migrating to using LDAP, but my LDAP server is only for user authentication, not allowing me to add groups. I still need to use groups as they are used for access control via the Apache Directory tags in my configuration. The alternative is to revisit the access control altogether, using php or something of the sort to limit access. this works for 'basic' authentication <Directory /misc/www/html/site> #LDAP & other config stuff irrelevant to issue Require ldap-group cn=<service>,ou=Groups,dc=<service>,dc=<org>,dc=com </Directory> attempted <Directory /misc/www/html/site> #LDAP & other config stuff irrelevant to issue #groups file from previous configuration using htpasswd #tried to tweak to match new user format, but I don't think it looks up in here AuthGroupFile /misc/www/htpasswd/groups #added the group, which is how it works when using htpasswd Require ldap-group cn=<service>,ou=Groups,dc=<service>,dc=<org>,dc=com group xyz </Directory>

• Windows 7 mouse multi selection on windows explorer with CTRL and point to select / single click to open

  - by bortao

  This is something that have annoyed me since i changed to Windows 7. I don't do double click for a long time now since windows introduced 1 click selection (Folder Options Click items as follows Single click to open an item). The problem is, when i click Control and hover over the items, they select/deselect automatically every small amount of mouse movement i make. What i want is to select/deselect the items only when i enter/exit them. So to deselect an item im hovering, i have to move the mouse out of it, and then back in. I'm using Intellimouse Explorer official drivers. (edit) Here's another related annoyance: When you are hovering something and move the mouse inside other item (Holding Ctrl) The new item may or may not be selected. If you continue moving the mouse it gets selected/deselected as you move. (more edit) I have found that the parameter HKCU\Control Panel\Mouse\MouseHoverHeight / MouseHoverWidth have some influence here. If it's set to 2, the item select/deselect really quickly as you move the mouse. When set to larger numbers, its slower. But setting to 20 or 200 don't seem to be much different.

• Formal separation marker of syslog events?

  - by Server Horror

  I've been looking at RFC5424 to find the formally specified marker that will end a syslog event. Unfortunately I couldn't find it. So If I wanted to implement some small syslog server that reacts on certain messages what is the marker that ends a message (yes commonly an event is a single line, but I just couldn't find it in the specification) Clarification: I call it event because I associate a message with a single line. An event could possibly be some thing like Type: foo Source: webservers whereas a message to me is this: Type: foo Source: webservers http://tools.ietf.org/html/rfc5424#section-6 defines: SYSLOG-MSG = HEADER SP STRUCTURED-DATA [SP MSG] neither STRUCTURED-DATA nor MSG tell me how these fields end. Especially MSG is defined as as MSG-ANY / MSG-UTF8 which expands to virtually anything. There's nothing that says a newline marks the end (or an 8 or an a for that matter). Given the example messages (section 6.5): This is one valid message, or 2 valid messages depending on wether you say that a HEADER element must never occur in any MSG element: literal whitespace <34>1 2003-10-11T22:14:15.003Z mymachine.example.com su - ID47 - <34>1 2003-10-11T22:14:15.003Z mymachine.example.com su - ID47 | is this an end marker? \t stands for a tab <34>1 2003-10-11T22:14:15.003Z mymachine.example.com su - ID47 -\t<34>1 2003-10-11T22:14:15.003Z mymachine.example.com su - ID47 | is this an end marker? \n stands for a newline <34>1 2003-10-11T22:14:15.003Z mymachine.example.com su - ID47 -\n<34>1 2003-10-11T22:14:15.003Z mymachine.example.com su - ID47 | is this an end marker? Either I'm misreading the RFC or there just isn't any mention. The sizes specified in the RFC just say what the minimum length is expected that I can work with...

• How do I connect remotely to SQL Server from Windows client?

  - by humble_coder

  Hi All, Having a bit of an issue connecting to SQL SERVER remotely from Windows. I've verified that all of my settings are correct via SQL SERVER MANAGEMENT STUDIO EXPRESS and SQL SERVER CONFIGURATION MANAGER. I can connect remotely using ODBC drivers from other OSes (e.g. OS X, Linux, etc). However, when I connect with the same credentials from a remote Windows machine using "SQL SERVER" as the driver I am told that the system cannot connect. I've tried creating an ODBC Data Source and I get the same error: Connection failed: SQLState: '01000' SQL Server Error: 14 [Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]ConnectionOpen(InvalidInstance()). Connection failed: SQLState: '08001' SQL Server Error: 14 [Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]Invalid Connection From the non-windows machines I can use the IP address of the SQL Server just fine. However, on the remote Windows machine, neither IP address nor named instance works. FYI, I can create an ODBC Data Source using the named instance on the machine actually running the SQL Server (but this is, of course, nothing special -- just proof that it isn't completely hosed). One interesting note: If I use SQL STUDIO 2005 from a Windows client machine, I can use the IP address to connect remotely. Still, the whole reason I bring this up is because I need to use a software package I've written to connect to SQL Server remotely from Windows machines as well. Previously the solution was only needed to xfer data from SQL Server into a PostGRES or MySQL database on non-Windows machines (due to DBA preference). However, now they also want to move the data from the legacy software to MySQL even on Windows. Any assistance would be most appreciated. Feel free to provide a full example connection string. Best

• TCP/UDP hole punching from and to the same NAT network

  - by Luc

  I was wondering if tcp/udp hole punching would still work when you are in the same network (behind a NAT), and what the packet's path would be. What happens when using hole punching on the same network, is that it will send a packet out with the same destination and source address. Only the source and destination port would differ. I imagine a router with NAT loopback enabled will handle this as it should, but how about other routers? Would they drop the packet, or would a router (the first?) from the ISP bounce the packet back after which it gets handled okay? I'm wondering because I was thinking about using this technique to circumvent a block between peers in a network (like a school network where clients can only access the internet, but any contact with each other is blocked). The only other option is to use a man in the middle as proxy (tunnel?). The disadvantage of this is that you have to have a server with significantly more bandwidth than one that would only do hole punching. Also the latency would increase significantly.

• iptables drops some packets on port 80 and i don't know the cause.

  - by Janning

  Hi, We are running a firewall with iptables on our Debian Lenny system. I show you only the relevant entries of our firewall. Chain INPUT (policy DROP 0 packets, 0 bytes) target prot opt in out source destination ACCEPT all -- lo * 0.0.0.0/0 0.0.0.0/0 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED ACCEPT tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 state NEW Chain OUTPUT (policy DROP 0 packets, 0 bytes) target prot opt in out source destination ACCEPT all -- * lo 0.0.0.0/0 0.0.0.0/0 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED LOGDROP all -- * * 0.0.0.0/0 0.0.0.0/0 Some packets get dropped each day with log messages like this: Feb 5 15:11:02 host1 kernel: [104332.409003] dropped IN= OUT=eth0 SRC= DST= LEN=1420 TOS=0x00 PREC=0x00 TTL=64 ID=18576 DF PROTO=TCP SPT=80 DPT=59327 WINDOW=54 RES=0x00 ACK URGP=0 for privacy reasons I replaced IP Addresses with and This is no reason for any concern, but I just want to understand what's happening. The web server tries to send a packet to the client, but the firewall somehow came to the conclusion that this packet is "UNRELATED" to any prior traffic. I have set a kernel parameter ip_conntrack_ma to a high enough value to be sure to get all connections tracked by iptables state module: sysctl -w net.ipv4.netfilter.ip_conntrack_max=524288 What's funny about that is I get one connection drop every 20 minutes: 06:34:54 droppedIN= 06:52:10 droppedIN= 07:10:48 droppedIN= 07:30:55 droppedIN= 07:51:29 droppedIN= 08:10:47 droppedIN= 08:31:00 droppedIN= 08:50:52 droppedIN= 09:10:50 droppedIN= 09:30:52 droppedIN= 09:50:49 droppedIN= 10:11:00 droppedIN= 10:30:50 droppedIN= 10:50:56 droppedIN= 11:10:53 droppedIN= 11:31:00 droppedIN= 11:50:49 droppedIN= 12:10:49 droppedIN= 12:30:50 droppedIN= 12:50:51 droppedIN= 13:10:49 droppedIN= 13:30:57 droppedIN= 13:51:01 droppedIN= 14:11:12 droppedIN= 14:31:32 droppedIN= 14:50:59 droppedIN= 15:11:02 droppedIN= That's from today, but on other days it looks like this, too (sometimes the rate varies). What might be the reason? Any help is greatly appreciated. kind regards Janning
