• Chrooted pygopherd fails to find new directories and files

  - by Carsten R

  I tried to setup a Pygopherd on my server. The default setup works fine, but when I try to change the gophermap to point to a new directory with a new file, I get an error message in my gopher client: --- [1] '/path/to/gopher/newdir' does not exist (no handler found) First I thought this is caused by the chroot in which pygopherd runs as default. But when I disable the chroot, the same error comes up. Did anyone successfully set up pygopherd or knows about a better gopher server?

• Deletion of SQL Profiler Trace files (.trc)

  - by Mark

  We've noticed a lot of .trc files in our SQL data folder (\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data) on our server. The date range for these files spans over one day and the total file size of all files together is about 21 gigs. I'd like to free up this space but I'm not sure if I can just delete the files manually through Windows Explorer or if I need to do anything in SQL, like run a command or script. Any ideas?

• Schema changes with replication

  - by Even Mien

  What are the steps to make a schema change to a SQL Server 2005 database using transactional replication? I'm trying to add a database column. I thought if I removed the article for the table, made the schema change, and then added the article for the table back that the schema change would replicate. I am now getting the following error every minute or so: SQL Server errors Replication-Replication Distribution Subsystem: agent [jobname] failed. Invalid column name 'NewColumn'.

• Strange mysql problem moving website from Ubuntu server to Mac server

  - by evan

  I'm moving a website (php/mysql) from an Ubuntu server to a OSX 10.6 server. I've set up apache to run php scripts and setup the newest version of mysql on the mac. I just copied all of the php files and dumped/imported all of the mysql databases (including the mysql users database). When I visit the page being served on the Mac the page is able to connect to the database, but not query. Specifically this function mysql_error() is returning this error message NO SUCH FILE OR DIRECTORY The reason it's strange is that I'm able to change the php connection strings for mysql on the Ubuntu server so that it points to the Mac server and the page works correctly (so it seems mysql is correctly set up on the mac and definitely contains all of the users and tables it should). Thinking it was something to do with file permissions on the mac, I've changed all of the files 755 and it hasn't helped. Any ideas? Thanks!! UPDATE: I've found this error which I'm relatively certain is related to this problem in /var/log/apache2/error_log PHP Warning: mysql_query(): A link to the server could not be established

• transfer code from one server to other server.

  - by Kamlesh Bhure

  I wanted to transfer new code into my new production server. I have code files on my development server. Instead of uploading files using FTP from my local machine, there is other way to transfer code from one server to other. What I am thinking I will make zip file of whole code to be transfer and place it in webroot. So that it would be accessible in internet with some link http://www.mydomain.com/code.tar.gz now on the other server i will just run command wget http://www.mydomain.com/code.tar.gz Will this transfer done in few seconds...? May I know is this correct approach?

• Default user profile getting filled with temp ie files

  - by Christoffer

  I have several Windows Server 2003 Terminal servers to service our domain users. Sometimes the Default User profile (C:\Documents and Settings\Default User) gets filled with tempoary internet files, so when a new user logs in, he gets a 1GB profile (instead of 20MB) that fills up the server fast. Why is it the default user profile gets filled up with files like that, by who and how do i prevent this?

• How can I automate my Linux computer to power off (and on preferably) under certain circumstances?

  - by Ashimema

  OK, So a little background; I've been using Windows Home Server as a Backup Appliance, Media Server and Share Server at home for some time. I decided it was costing me allot of juice so very early on added the "Lights Out" add-on to ensure it was only running as and when needed. I'm now looking to switch to a Linux based server and I'm looking for a similar tool/set of tools for advanced power management. Now the question; Anyone got any all-in-one suggestions (i.e with client parts for both Windows and Linux and a server part for the Linux server), or can anyone simply verify that I'll need to set-up all the individual bits for this myself separately? (A tool similar to "[SmartPower][2]" but for linux would be a great start)

• Map path server with workgroup to other server with domain

  - by bzamfir

  I have the following situation, and I need some help to setup properly I have two VPS (hosted with the same provider, maximumasp). Server A is 2008R2, set with WORKGROUP, and server B is 2012, set with domain, maximumasp.local. On server A I have an old web app, which uses a special folder, c:\MyUploads, to store uploaded files. App is using this using an appSetting. It will be kept running for a while for safety / compatibility reasons. I installed a new version of the application on server B, running under AppPoolIdentity. Both instances of the app (A and B) will connect to the same database, so I need them to share also the access to upload folder c:\MyUploads. How should I setup the app on machine B to access the folder c:\MyUploads ? My idea is to share the folder as \A\MyUploads, and then map it to server B. But the problem is, I don't know to give Read/write to c:\MyUploads on machine A to IIS AppPools\ on machine B I was trying a test, and shared the c:\MyUploads to Everyone, ReadWrite. I was able to access it from machine B using \\MyUploads But when app from machine B tried to access a file, it gave error. Any idea how can I accomplish this? Some advice on best practices for such situation would be great. Thank you

• Server to server replication and CPU and 32k\ corrupt doc

  - by nick wall

  Summary: if database contains a doc with 32K issue or corrupt, on server to server replication it causes marked increase in CPU in nserver.exe task, which effectively causes our server(s) to slow right down. We have a 5 server cluster (1 "hub" and 4 HTTP servers accessed via reverse proxy and SSO for load balancing and redundancy). All are physically located next to each other on network, they don't have dedicated network\ ports for cluster or replication. I realise IBM recommendation is dedicated port for cluster. Cluster queues are in tolerance and under heavy application user load, i.e. the maximum number of documents are being created, edited, deleted, the replication times between servers are negligible. Normally, all is well. Of the servers in the cluster, 1 is considered the "hub", and imitates a PUSH-PULL replication with it's cluster mates every 60mins, so that the replication load is taken by the hub and not cluster mates. The problem we have: every now and then we get a slow replication time from the hub to a cluster mate, sometimes up to 30mins. This maxes out the nserver.exe task on the "cluster mate" which causes it to respond to http requests very slowly. In the past, we have found that if a corrupt document is in the DB, it can have this affect, but on those occasions, the server log will show the corrupt doc noteId, we run fixup, all well. But we are not now seeing any record of corrupt docs. What we have noticed is if a doc with the 32K issue is present, the same thing can happen. Our only solution in that case is to run a : fixup mydb.nsf -V, which shows it is purging a 32K doc. Luckily we run a reverse proxy, so we can shut HTTP servers down without users noticing, but users do notice when a server has the problem! Has anyone else seen this occur? I have set up DDM event handlers for many of the replication events. I have set the replication time out limit to 5 mins (the max we usually see under full user load is 0.1min), to prevent it rep'ing for 30mins as before. This ia a temporary work around. Does anyone know of a DDM event to trap the 32K issue? we could at least then send alert. Regarding 32K issue: this prob needs another thread, but we are finding this relatively hard to find the source of the issue as the 32K event is fairly rare. Our app is fairly complex, interacting with various other external web services, with 2 way data transfer. But if we do encounter a 32K doc, we can't look at field properties, so we can't work out which field has issue which would give us a clue as to which process is culprit. As above, we run a fixup -V. Any help\ comments on this would be gratefully received.

• Installing ubuntu server as linux distro on dell server - what drivers will be missed

  - by Cookie

  Dell (via USC) unpacks specific drivers for both RedHat and Suse to use after installation on its servers. As Ubuntu server isn't officially supported, this clearly isn't happening for Ubuntu. Is Ubuntu server then running with native drivers? In that case, which drivers are native with Ubuntu, and aren't (e.g. are Dell replaced) with RedHat/Suse? Are dell optimized drivers available for Ubuntu somewhere? Can the ones for RedHat or Suse be used with Ubuntu? Are there disadvantages of this lack of fine-tuned drivers, and if yes, what are they? Would they make the switch (and extra costs, as both RedHat and Suse Enterprise aren't cheap) away from the free Ubuntu server worthwhile? Dell recommends Canonical's commercial support for Ubuntu server on its machines, is this recommendable? Do they offer fine-tuned Dell drivers to replace native drivers?

• PPTP VPN Server issue : server = centOS & client = windows 7

  - by jmassic

  I have a CentOS server configured as a PPTP VPN Server. The client is a Windows 7 with "Use default gateway on remote network" in advanced TCP/IPv4 properties enable. He can connect to CentOS without any problem and can access to: The Box of his ISP (http://192.168.1.254/) The CentOS server The website which is hosted by the server (through http://) But he canNOT access any other web service (google.com or 74.125.230.224) I am a beginner with web servers so I do not know what can cause this problem. Note 0 : The Windows 7 user must be able to access the whole internet through the CentOS PPTP proxy. Note 1 : With "Use default gateway on remote network" in advanced TCP/IPv4 UNCHECKED it is the same problem Note 2 : With "Use default gateway on remote network" in advanced TCP/IPv4 UNCHECKED AND "disable class based route addition" CHECKED the Win 7 can access google but with the ISP IP (no use of the VPN...) See Screenshot Note 3 : I have made a echo 1 > /proc/sys/net/ipv4/ip_forward and a iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

/lib/x86_64-linux-gnu/libz.so.1.2.3.4Connection to stageserver.dockphp.com closed. After some debugging, I was able to narrow it down to a few things. For some reason the sshd daemon is running as root:www-data (apache user) instead of root. My ftp connection works but ssh over terminal fails. I have no idea whether it is getting caused due to suPHP or not (because that is the only place where user permission's etc. change). I really need to narrow it down and fix it asap. Thanks a lot!

• Configuring external SMTP server on Azure VM - messages staying in queue

  - by Steph Locke

  I have an external SMTP provider: auth.smtp.1and1.co.uk I am trying to send SQL Server Reporting Services emails via this on an Windows 2012 Azure VM. It is configured sufficiently correctly for emails to be generated, but I've not configured something or mis-configured something as the emails then stay in the queue. Setup details Configured SMTP Virtual Server General: IP Address: Fixed value Access: Access Control: Authentication: ticked Anonymous access Access: Connection Control: All except the list below (which is empty) Access: relay restrictions: Only the list below (which contains 127.0.0.1), ticked 'allow all..' option Delivery: Outbound Security...:Basic Authentication with username and password completed, ticked TLS encryption Delivery: Outbound connections...:TCP port=587 Delivery: Advanced: FQDN=ServerName, smarthost=auth.smtp.1and1.co.uk I then set the following SSRS rsreportserver.config values: <SMTPServer>100.92.192.3</SMTPServer> <SendUsing>2</SendUsing> <SMTPServerPickupDirectory> c:\inetpub\mailroot\pickup </SMTPServerPickupDirectory> <From>[email protected]</From> Tried so far 1) turning the smtp service off and on again (just in case) 2) run SMTPDiag with no errors (also no emails) 3) tried turning off the firewall for the ports (and more generally to see if it made a difference) 4) tried generation from powershell which resulted with message in queue 5) added 25 and 857 as endpoint 6) perused the event log and found some warnings that appear to be about the recipient Message delivery to the remote domain 'gmail.com' failed for the following reason: Unable to bind to the destination server in DNS. Message delivery to the host '212.227.15.179' failed while delivering to the remote domain 'gmail.com' for the following reason: The remote server did not respond to a connection attempt. 7) tried pinging but this appears to be blocked on azure 8) tried more powershell sending on different domains variants (localhost, boxname, internal ip used in smtp properties, 127.0.0.1) - none resulting in success 9) tried adding a remote domain - no change Could anyone recommend what step 10 should be in fixing this issue please?

• mount.nfs: access denied by server while mounting (null), can't find any log information

  - by Mark0978

  Two ubuntu servers: 10.0.8.2 is the client, 192.168.20.58 is the server. Between the 2 machines, Ping works, ssh works (in both directions). From 10.0.8.2 showmount -e 192.168.20.58 Export list for 192.168.20.58: /imr/nfsshares/foobar 10.0.8.2 mount.nfs 192.168.20.58:/imr/nfsshares/foobar /var/data/foobar -v mount.nfs: access denied by server while mounting (null) Found several things online, tried them all and still can't find any log information anywhere. On the server: [email protected]:/var/log# cat /etc/hosts.allow sendmail: all ALL: 10.0.8.2 /etc/hosts.deny is all comments How can I get a trail of log statements to figure this out? What does it take to get some logging so I have some idea of WHY it won't mount?

• VMware Tools in Ubuntu guest on VMware Server 2 do not build

  - by ulf

  When trying to build the VMware tools in my Ubuntu 9.10 64 bit guest on a VMware Server 2.0.2 host with Debian 5 I'm getting strange errors like: Building the vmmemctl module. Using 2.6.x kernel build system. make: Gehe in Verzeichnis '/tmp/vmware-config8/vmmemctl-only' make -C /lib/modules/2.6.31-19-server/build/include/..

I googled half the Internet but couldn't come to a solution. None of the kernel modules seems to build correctly. While googling I read something about a bug in this kernel tree.

• Unexplained CPU and Disk activity spikes in SQL Server 2005

  - by Philip Goh

  Before I pose my question, please allow me to describe the situation. I have a database server, with a number of tables. Two of the biggest tables contain over 800k rows each. The majority of rows are less than 10k in size, though roughly 1 in 100 rows will be 1 MB but <4 MB. So out of the 1.6 million rows, about 16000 of them will be these large rows. The reason they are this big is because we're storing zip files binary blobs in the database, but I'm digressing. We have a service that runs constantly in the background, trimming 10 rows from each of these 2 tables. In the performance monitor graph above, these are the little bumps (red for CPU, green for disk queue). Once ever minute we get a large spike of CPU activity together with a jump in disk activity, indicated by the red arrow in the screenshot. I've run the SQL Server profiler, and there is nothing that jumps out as a candidate that would explain this spike. My suspicion is that this spike occurs when one of the large rows gets deleted. I've fed the results of the profiler into the tuning wizard, and I get no optimisation recommendations (i.e. I assume this means my database is indexed correctly for my current workload). I'm not overly worried as the server is coping fine in all circumstances, even under peak load. However, I would like to know if there is anything else I can do to find out what is causing this spike? Update: After investigating this some more, the CPU and disk usage spike was down to SQL server's automatic checkpoint. The database uses the simple recovery model, and this truncates the log file at each checkpoint. We can see this demonstrated in the following graph. As described on MSDN, the checkpoints will occur when the transaction log becomes 70% full and we are using the simple recovery model. This has been enlightening and I've definitely learned something!

• Ubuntu Server running VNC

  - by xwapilot

  I have access to four computers: 1 Ubuntu Server desktop (Version 10.04) 1 Mac Mini (Snow Leopard) 1 Windows desktop (Windows 7) 1 Windows laptop (Windows Vista) The first three will always be on the home network. My goal is to SSH from the laptop into the server and be able, through VNC (or another remote desktop software), to control the windows and mac computers. The goal of this would be a slightly heightened network security over using VNC to directly access the mac or windows desktop. I have successfully used SSH to connect to the server, but have not been able to successfully implement the remote desktop connection. I would appreciate help doing so. Here's what I've done so far: As per instructions here: http://www.stuartellis.eu/articles/vnc-on-linux/ I installed the following: vnc4server – the main VNC server software vnc-java – enables access from Web browsers with Java support xvnc4viewer – a basic VNC viewer I then set up a password using the vncpasswd command. To attempt to connect to the mac, I followed directions I found in a thread at superuser. com and went to "System PreferencesSharing" and enabled "Screen Sharing". Subsequently, I tried entering the following commands into Ubuntu: vncviewer mac_ip_address::5904 vncviewer mac_ip_address:0 vncviewer mac_ip_address:1 They all returned the following: VNC Viewer Free Edition 4.1.1 for X - built Apr 9 2010 18:41:55 Copyright (C) 2002-2005 RealVNC Ltd. See http ://www .realvnc. com for information on VNC. vncviewer: unable to open display "" I'm sure I'm missing something important, but I'm not sure what it is. Do I need to have a GUI installed, or did that come with the vnc packages I installed?
