• Cannot connect to my EC2 instance because of "Permission denied (publickey)"

  - by Burak

  In AWS console, I saw that my key pair was deleted. I created a new one with the same name. Then I tried to connect with ssh -v -i sohoKey.pem ec2-user@******.compute-1.amazonaws.com Here's the output: macs-MacBook-Air:~ mac$ ssh -v -i sohoKey.pem ec2-user@******.compute-1.amazonaws.com OpenSSH_5.6p1, OpenSSL 0.9.8r 8 Feb 2011 debug1: Reading configuration data /etc/ssh_config debug1: Applying options for * debug1: Connecting to ********.compute-1.amazonaws.com [*****] port 22. debug1: Connection established. debug1: identity file sohoKey.pem type -1 debug1: identity file sohoKey.pem-cert type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.3 debug1: match: OpenSSH_5.3 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.6 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host '*******.compute-1.amazonaws.com' is known and matches the RSA host key. debug1: Found key in /Users/mac/.ssh/known_hosts:3 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Offering RSA public key: sohoKey.pem debug1: Authentications that can continue: publickey debug1: Trying private key: sohoKey.pem debug1: read PEM private key done: type RSA debug1: Authentications that can continue: publickey debug1: No more authentication methods to try.

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

  - by user65567

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

• Setting up Git / Apache on Windows

  - by yodaj007

  I'm following this tutorial to set up a personal Git server on Apache on my Windows 7 box. However, when I add the following to my httpd.conf, Apache throws an error when I try to start it. Can anyone assist in fixing whatever is wrong? SetEnv GIT_PROJECT_ROOT C:/Repositories SetEnv GIT_HTTP_EXPORT_ALL ScriptAliasMatch "(?x)^/(.*/(HEAD | info/refs | objects/(info/[^/]+ | [0-9a-f]{2}/[0-9a-f]{38} | pack/pack-[0-9a-f]{40}.(pack|idx)) | git-(upload|receive)-pack))$" "C:/Program Files (x86)/git/libexec/git-core/git-http-backend.exe/$1" This is a fresh install of Apache. The only other change I've made to the config file is telling Apache to listen on port 9000 (IIS is listening on 80). This is the error from my event logs: The Apache service named reported the following error: ScriptAliasMatch takes two arguments, a regular expression and a filename . I tried putting all of the text on one line, like so: ScriptAliasMatch "(?x)^/(.*/(HEAD | info/refs | objects/(info/[^/]+ | [0-9a-f]{2}/[0-9a-f]{38} | pack/pack-[0-9a-f]{40}.(pack|idx)) | git-(upload|receive)-pack))$" "C:/Program Files (x86)/git/libexec/git-core/git-http-backend.exe/$1" But nada.

• Intel Core i7 QuadCore on HP Pavilion dv7 Overheating Issues

  - by kellax

  I bought a brand new HP notebook: HP Pavilion dv7-6b21em BeatsAudio edition. The notebook is about 2 months old and has pretty nasty overheating problem. I mainly use it for development however i do play some games. The disturbing thing is that the computer is loud on pretty simple tasks. Here are the specs: CPU: Intel Core i7-2670QM QuadCore ( 8 threads ) @ 2.20 GHz RAM: ( 8GB ) 2x 4GB @ 1066 HDD: 1TB 7200 GPU: ATI Radeon HD 6770M 1GB Dedicated DDR OS: Windows 7 64bit Enterprise I have an external monitor runing on VGA port an 22' Samsung SyncMaster S24B300 CPU Heat Statistics Platform: rPGA 988B (Socket G2) Frequency: cca. 3000 Mhz VID: 1.1809 - 1.2059 v Revision: D2 CPUID: 0x206A7 TDP: 45.0 Wats, Lithographu: 32 nm Heat: Tj.

When i run a game the heat jumps to whopping 90-97*C. It has not shut down due to overheating yet but the loud fan is pretty annoying considering I'm not really doing anything stressfull. Is there anything i can do to fix this is it maybe a BIOS issue ? I have all drivers updated tho to the latest. I have very few background processes running consuming bare 2GB of RAM and about 2% of CPU. I had it serviced they said there is nothing wrong with it. But i feel that a Notebook that costs 1.2k Euros cant be like this.

• Mod_Proxy_AJP set up issues

  - by TripWired

  I'm trying to set up Tomcat behind Apache using mod_proxy_ajp. After tons of messing around with the configs I am stuck at a 403 page when trying to access tomcat. I had a 404 before but apparently something I changed along the way fixed that. I'm not sure which setting to change at this point.

• 426 Connection closed; transfer aborted.

  - by Jiaoziren

  Hi, I have an IIS FTP set up on Windows 2003 SP2 (S1). Everyday in the early morning, a script on another server (S2) will run and initiate FTP transfer of pulling log files from S1 to S2. The FTP client we're using is built-in FTP.exe in Windows 2000 on S2. Recently we replaced S1 with a new server however we kept the IP address. There are multiple IP addresses on new S1. Ever since the new S1 was in place, the '426 Connection closed; transfer aborted.' errors haven been occuring randomly. The log indicated that the transfer started ok however the file cannot be transferred completely, as per log below: mget access*.log 200 Type set to A. 200 PORT command successful. 150 Opening ASCII mode data connection for access02232010.log(205777167 bytes). 426 Connection closed; transfer aborted. ftp: 20454832 bytes received in 283.95Seconds 72.04Kbytes/sec. The firewall monitor suggested that the connection was setup in passive mode however I've been told that MS FTP.exe doesn't support passive mode. Though I can see the response of 'entering passive mode' from server when typing in 'quote pasv'. My network admin has told me to try the transfer in active mode however I don't know how to open active mode on client side. It's getting really frustrating. Wish someone here has the right knowledge/experience could shed me a light. Cheers.

• Remote Desktop to Server 2008R2 fails from one particular Win7 client

  - by Jesse McGrew

  I have a VPS running Windows Web Server 2008 R2. I'm able to connect using Remote Desktop from my home PC (Windows 7), personal laptop (Windows 7), and work laptop (Windows XP). However, I cannot connect from my work PC (Windows 7). I receive the error "The logon attempt failed" in the RDP client, and the server event log shows "An account failed to log on" with this explanation: Subject: Security ID: NULL SID Account Name: - Account Domain: - Logon ID: 0x0 Logon Type: 3 Account For Which Logon Failed: Security ID: NULL SID Account Name: username Account Domain: hostname Failure Information: Failure Reason: Unknown user name or bad password. Status: 0xc000006d Sub Status: 0xc0000064 Process Information: Caller Process ID: 0x0 Caller Process Name: - Network Information: Workstation Name: JESSE-PC Source Network Address: - Source Port: - Detailed Authentication Information: Logon Process: NtLmSsp Authentication Package: NTLM Transited Services: - Package Name (NTLM only): - Key Length: 0 I can connect from the offending work PC if I start up Windows XP Mode and use the RDP client inside that. The server is part of a domain but my account is local, so I'm logging in using a username of the form hostname\username. None of the clients are part of a domain. The server uses a self-signed certificate, and connecting from home I get a warning about that, but connecting from work I just get the logon error.

• SCVMM 2008 R2 problems migrating VM from VS2005 to Hyper-V host

  - by Scott Ivey

  I have System Center Virtual Machine Manager 2008 R2 installed, and have a Hyper-V R2 host and a Virtual Server 2005 host. I'm trying to migrate my machines from the VS2005 host to the Hyper-V host, and keep getting the following error... VMM is unable to complete the requested file transfer. The connection to the HTTP server myserver.mydomain.local could not be established. (Unknown error (0x80072efd)) Recommended Action Ensure that the HTTP service and/or the agent on the machine myserver.mydomain.local are installed and running and that a firewall is not blocking HTTPS traffic. (Note - migrations between Hyper-V hosts managed by the VMM server work fine - my problem is just going from VS2005-Hyper-V hosts) I have no firewalls turned on on either of the servers, and no firewalls in the middle. I've looked all over for answers to this problem, and am getting nowhere. All the articles I find when searching are talking about either V2V or P2V - and i'm just trying to do a straight migrate VM. I've tried rebooting the boxes, changing the BITS SSL port number, restarting services, triple-checking firewalls, etc. Does anyone have any good suggestions as to how I can resolve this problem?

• Add Network Printer drivers in Windows 7/Server 2008 R2?

  - by Matias Nino

  I'm running a 64 bit Windows 7 / Windows 2008 R2 workstation that I just installed. I need to add a printer that is shared on the network from a 32bit Windows 2000 print server. This is an HP LaserJet 5Si printer, the drivers for which HP tells me are automatically built into Windows 7/R2. However, whenever I connect to the printer or try to add it, I get the following screen: Upon clicking OK, I get this screen asking me to locate the driver: How can I possibly locate a driver that is SUPPOSED TO BE NATIVELY SUPPORTED on Windows 7/R2? The tough part is that this printer is one of many shared on a server and does not have a direct IP address. Even worse: I have no access to the print server so I cannot put the 64 bit drivers on there. Any ideas? UPDATE: HP doesn't make a Vista driver either. It claims it is natively supported by Vista and 7, which is true because I am able to create a local printer on a fake tcp/ip port and Windows lets me pick the proper driver. However, when adding from the network, Windows does not let me select a driver and demands an INF. I tried searching the entire sub-structure of the C:\Windows directory and could not find any INF files that contain HP information. The INF might be located somewhere in the Windows installation DVD, but all the files on the DVD are compressed and unrecognizable. UPDATE #2 I installed the proper printer driver as a local printer (with no printer attached) and it installed. However, this did not change the fact that it STILL asks me to provide drivers when connecting to the networked printer.

• What device can create wireless network while connecting to an ethernet router

  - by Nicolo

  Hi, I have access to an ethernet port of a wireless router. I simply connect my laptop to it via an ethernet cable. There are a total of four such ports on the wireless router. Now I want to connect a device (a wireless access point? wireless bridge? wireless switch?) via an ethernet cable to one of the other ethernet ports of the router. I want this device to act as a kind of wireless switch - it should "split" the ethernet connection coming from the router to two or more computers that connect to this device via a wireless. Basically, I have a wireless router with its wireless function switched off. I don't know the password for that router so can't activate the wireless function. Don't know the password of the ISP either. The only thing I can do is to connect via ethernet cable to the wireless router and this does not require a password. Now I want to use that connection and build a wireless upon it. What kind of device do I need? I am not really very well informed about network management and find the descriptions "wireless access point", "wireless bridge", "wireless switch" confusing. I know what an ethernet switch is - what I need is a device which would do the same but by allowing the clients to connect to it via a wireless. What kind of device would do that? Any recommendations about specific products?

• Tomcat 6 Windows Server 64 Redirect Connector Fails

  - by Rafe

  So is there some problem with running the Tomcat connectors under a 64 bit windows OS? Here's my configuration: Windows Server 2003 64 bit Intel Xeon Tomcat 6.0.26 JVM 1.6.0 (64bit) ISAPI Redirect Connector 1.2.30.0 (64 bit) Calling the IP address of the site with :8080 brings up the tomcat page so I know that's running and the examples all work so its obviously not having a problem with the JVM. Calling the site ip on port 80 however gives me error 324 - looking at the application log on windows shows "Could not load all ISAPI filters for site/service. Therefore startup aborted". The ISAPI filter page under the web site properties shows the status of this filter to be down with a red arrow. The ISAPI filter name is jakarta and there is a corresponding virtual directory set up in the root of the site pointing to the same directory as the filter. The jakarta web service extension is also pointing to the required dll (c:\program files\apache software foundation\jakarta isapi redirector\bin\isapi_redirect.dll). Incidentally, this same problem occurs when trying to use Tomcat 5.5. I've also tried swapping out various redirect versions. It's really odd because I got it to work once with a version of the redirector that came with Plesk but I've since uninstalled everything to do with plesk and even trying to use the plesk-compiled dll doesn't work now. I am pulling my hair out on this, any ideas?

• Why RSA SSH authentication only works after console log-in?

• Getting 400 Bad Request when requesting by server name on nginx/uwsgi

  I'm trying to run 2 different sites on nginx via different ports (they each have a load balancer that points to the appropriate port). The first site work perfectly. The second site...

• Web server with static IP from cable provider

  - by Dmitri

  I have a subscription to 5 static IP addresses. I want to run a web server from behind a router. My network config is as follows: Server's local address is 10.1.10.2, has IIS running on it, port 80 and 443 (IIS is not my fault, had to be done) the server's ip address is static, the subnet mask is 255.255.255.0, gateway is 10.1.10.1, which is the local address of the cable modem / router / gateway thingy. All looks to be in textbook order as far as the LAN goes. I can get to anything on my LAN from any computer on my LAN, whether they have static IP or get it through DHCP from the cable modem/router thingy. however, I have no internet access form any of my LAN computers. I called Comcast tech support and they say they can connect to my modem/router just fine and can actually use it to ping any computer on the internet or any computer on my LAN from the router/modem (i checked, myself, this is in fact the case). However, nothing on my LAN has internet connectivity. I tried pinging the DNS servers, nothing. I tried directly typing in web sites' IP addresses, nothing, so doesn't seem to be a DNS issue. Any Ideas? What malfunction of a router could be causing such weird behavior? nay ideas or educated guesses are very much appreciated.

• Does any Certificate Authority support both SAN and wildcards?

  - by nicholas a. evans

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

• centos postfix send email problem

• How to get html/css/jpg pages server by both apache & tomcat with mod_jk

  - by user53864

  I've apache2 and tomcat6 both running on port 80 with mod_jk setup on ubutnu servers. I had to setup an error document 503 ErrorDocument 503 /maintenance.html in the apache configuration and somehow I managed to get it work and the error page is server by apache when tomcat is stopped. Developers created a good looking error page(an html page which calls css and jpg) and I'm asked to get this page served by apache when tomcat is down. When I tried with JkUnMount /*.css in the virtual hosting, the actual tomcat jsp pages didn't work properly(lost the format) as the tomcat applications uses jsp, css, js, jpg and so on. I'm trying if it is possible to get .css and .jpg served by both apache and tomcat so that when the tomcat is down I'll get css and jpg serverd by apache and the proper error document is served. Anyone has any technique? Here is my apache2 configuration: vim /etc/apache2/apache2.conf Alias / /var/www/ ErrorDocument 503 /maintenance.html ErrorDocument 404 /maintenance.html JkMount / myworker JkMount /* myworker JkMount /*.jsp myworker JkUnMount /*.html myworker <VirtualHost *:80> ServerName station1.mydomain.com DocumentRoot /usr/share/tomcat/webapps/myapps1 JkMount /* myworker JkUnMount /*.html myworker </VirtualHost> <VirtualHost *:80> ServerName station2.mydomain.com DocumentRoot /usr/share/tomcat/webapps/myapps2 JkMount /* myworker JkMount /*.html myworker </VirtualHost>

• mysqld_safe Can't log to error log and syslog at the same time. Remove all --log-error configuration options for --syslog to take effect

  When I'm trying to install MySQL 5.5 community edition on my Ubuntu 10.04 by compiling the source code, I met the following problem: $ fg % 1 sudo ../bin/mysqld_safe --basedir=/usr/local/mysql_community_5.5/data --user=mysql --defaults-file=/etc/my.cnf [sudo] password for linnan: Sorry, try again.

• How to push changes from Test server to Live server?

  - by anonymous

  As a beginner, I finally noticed the issue with making changes to the live server I've been working on, now that I have a couple users on it, since I bring it down so often. I created an EC2 image of my live server and set up a separate instance on EC2, so now I have 2 EC2 instances, Stage and Production. I set up GitHub and push changes to stage and test my code there, and when it's all done and working, I push it to the production branch, and everything is good. And there is a slight issue here since I name my files config_stage.js and config_production.js and set up .gitignore on each server, and in my code, I would have it read the ENV flags and set up the appropriate configs, is this the correct approach? And my main question is: how do you keep track of non-code changes to the server? For example, I installed HAProxy, Stunnel, Redis, MongoDB and several other things onto the Stage server for testing and now that it's all working and good, how do I deploy them to production? Right now, I'm just keeping track of everything I installed and copying configuration files over, which is very tedious and I'm afraid I may have missed a step somewhere. Is there a better way to port these changes over from my test server to my live server?

  - by Sevki

  I am trying to connect to my MSSQL server 2008 web instance and im failing horribly... i get the error 26 and before you jump on me i have done these Check the spelling of the SQL Server instance name that is specified in the connection string. Use the SQL Server Surface Area Configuration tool to enable SQL Server to accept remote connections over the TCP or named pipes protocols. For more information about the SQL Server Surface Area Configuration Tool, see Surface Area Configuration for Services and Connections. Make sure that you have configured the firewall on the server instance of SQL Server to open ports for SQL Server and the SQL Server Browser port (UDP 1434). Make sure that the SQL Server Browser service is started on the server. in addition to theese i have disabled the firewall completely and tried other ports nothing works the same credentials work on the server but not on the client. this is the exact error message A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

• How can I filter /var/adm/wtmpx on Solaris 10?

  - by Yanick Girouard

  Some of our Solaris 10 servers are monitored using SiteScope, which uses Telnet to probe certain ports (SSH is one of them) every few minutes. This is creating an insane amount of lines in /var/adm/wtmpx, and eventually make it so big (2,5G+) that we can no longer run the last command, or that the uptime command is unable to accurately show the true uptime of the server. The error we get when trying to run the last command is this: /var/adm/wtmpx: Value too large for defined data type I have found ways we can clean this accounting log using a cron job (with the command /usr/lib/acct/fwtmp), and this works. This is not the issue. I was wondering if there would be a way to simply prevent connections from the monitoring user (in our case, user monsite) from creating entries in this accounting log at all. Is this possible, and if so, how can I do it? I've looked around and searched Google for a while, but couldn't find an answer to this question. NOTE: We are very well aware that the monitoring solution we employ is perhaps not the best one, but we cannot change it at this time. Therefore, suggesting that we change it is not pertinent to this question. If you want to read more on the Sitescope monitoring solution we employ for those servers, please see its documentation here and look for Port Monitor, and Connecting to remote UNIX servers, which explains how it works.
