  • HAProxy not passing SSL traffic in TCP mode (unknown protocol)

    - by David
    Hi, I've got a HAProxy LB solution setup and working correctly. All HTTP traffic on port 80 is being passed through succesfully. I'm now trying to get SSL traffic to work (in TCP mode and on just one server for now) however I keep getting the following error when testing via openssl: 26396:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:588: However, when I try the same test (openssl s_client -connect) on the web servers IP address and hostname, everything seems to look OK. I can setup a hosts record locally and confirm that the browsers are picking up the SSL certificate succesfully for the domain. I guess this has led me to the conclusion that there is a problem at the HAProxy setup I have, so would really appreciate some advice here. frontend https-c-in bind 178.79.xxx.xxx:443 mode tcp default_backend c-https backend c-https balance source option ssl-hello-chk option httpclose server c-web-01 192.168.xxx.xxx:443 check inter 2000 rise 2 fall 5

  • Any problems usinga GoDaddy SSL certificate on a Cisco ASA firewall?

    - by Richard West
    I need to purchase and install a SSL certificate on my Cisco ASA firewall. This will allow my VPN users to connect to my ASA without receiving the certificate error from the untrusted self assigned SSL certificate that is currently on the ASA. I had good experiences with the SSL certificates that GoDaddy sells. However, I'm concerned about using them. On my web servers I have to also install GoDaddy's "intermediate certificate bundle". On the ASA I do not think that I will be able to preform anything like this. I do not fully understand what the "intermediate certificate bundle" does, but obviously it's important. So my question is can I use a GoDaddy SSL certificate on an ASA without my users getting any type of warning or error about connecting to a site that using an untrusted SSL certificate. I need this to be as simple as possible for my end users and warning messages are always scary :) Thanks!

  • Installing ikiwiki on nginx - fastcgi/fcgi wrapper

    - by meder
    My ultimate goal is to setup ikiwiki, my current goal is to get a fcgi wrapper working for nginx, so I can move on to the next step... The ikiwiki page points out this page as an example for a fcgi wrapper: http://technotes.1000lines.net/?p=23 So far I've installed the ikiwiki and libfcgi-perl modules through aptitude: aptitude install libfcgi-perl aptitude install ikiwiki It installed those packages as well as some minimal dependency packages. So the next step following the guide at technotes, I grabbed http://technotes.1000lines.net/fastcgi-wrapper.pl but I'm not sure where to actually place this file... do I run it as a service? The script makes a socket file in /var/run/nginx but that directory does not exist.. do I manually create it? So in addition to the .pl file for the cgi wrapper, I need to also define a separate cgi file for parameters. If my conf looks like this... server { listen 80; server_name notes.domain.org; access_log /www/notes/public_html/notes.domain.org/log/access.log; error_log /www/notes/public_html/notes.domain.org/log/error.log; location / { root /www/notes/public_html/notes.domain.org/public/; index index.html; } } And I don't have a cgi-bin directory, where exactly should I create it within my structure, and regarding that I'd obviously have to update the below before I include it in my conf, but I'm just not exactly sure how this would work out. # /cgi-bin configuration location ~ ^/cgi-bin/.*\.cgi$ { gzip off; fastcgi_pass unix:/var/run/nginx/perl_cgi-dispatch.sock; [1]* fastcgi_param SCRIPT_FILENAME /www/blah.com$fastcgi_script_name; [2]* include fastcgi_params; [3]* } Also since the user is www-data and /var/run is root owned, what's the proper way of giving it access? Any tips appreciated.

  • Cannot start session without errors in phpMyAdmin running Nginx with PHP-FPM

    - by Infinity
    Whenever I open phpMyAdmin from my VPS I get the following error: Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly. I have researched it, but cant seem to find a solution, I have done the following: Cleared cache and cookies Checked the php.ini (see below) Checked the logs (found nothing relevant) Given the correct permissions. [by sudo chown -R root:nginx /home/humza/pma] I am running Nginx with PHP-FPM, I have php-mysql and all that working fine but I can't get phpMyAdmin to work.

  • Thunderbird msi installer package

    - by Comradin
    Hello, I am in need of a thunderbird msi (Microsoft Installer) package which can be deployed via group policies using Microsoft ActiveDirectory. I am very pleased with the Firefox packaged provided by FrontMotion but unfortunately they do not have packages for Thunderbird. sob sob I guess, I could try to do the packaging myself, or do all of the installations by hand :( I did some searches and found very outdated packages by ZettaServe, but no current releases, yet.. Anyone using .msi packaged Thunderbird installations? If you have msi packages, where did you get them from? regards, Comradin

  • DNS lookup failures while accessing my website some proxy error

    - by Bond

From past 6 months many of my domains wer accessible as http://site1.myserver.com http://site2.myserver.com http://site3.myserver.com http://site4.myserver.com All these were Reverse Proxy configurations.

  • Configure Postfix to send/relay emails Gmail (smtp.gmail.com) via port 587

    - by tom smith
    Hi. Using Centos 5.4, with Postfix. I can do a mail [email protected] subject: blah test . Cc: and the msg gets sent to gmail, but it resides in the spam folder, which is to be expected. My goal is to be able to generate email msgs, and to have them appear in the regular Inbox! As I understand Postfix/Gmail, it's possible to configure Postfix to send/relay mail via the authenticated/valid user using port 587, which would no longer have the mail be seen as spam. I've tried a number of parameters based on different sites/articles from the 'net, with no luck. Some of the articles, actually seem to conflict with other articles! I've also looked over the stacflow postings on this, but i'm still missing something... Also talked to a few people on IRC (Centos/Postfix) and still have questions.. So, i'm turning to Serverfault, once again! If there's someone who's managed to accomplish this, would you mind posting your main.cf, sasl-passwd, and any other conf files that you use to get this working! If I can review your config files, I can hopefully see where I've screwed up, and figure out how to correct the issue. Thanks for reading this, and any help/pointers you provide! ps, If there is a stackflow posting that speaks to this that I may have missed, feel free to point it out to me! -tom

  • Why does snmp fail to use its own MIBs?

    - by chrisdew
    I've done a fresh install of Ubuntu 12.04LTS, and installed the snmpd and snmp packages. If I type: snmpwalk -m ALL -v2c -c public localhost 1.3 I get swathes of errors, of the form: Cannot adopt OID in SQUID-MIB: cacheClients ::= { cacheProtoAggregateStats 15 } Cannot adopt OID in NET-SNMP-EXTEND-MIB: nsExtendLineIndex ::= { nsExtendOutput2Entry 1 } Cannot adopt OID in NET-SNMP-EXTEND-MIB: nsExtendOutLine ::= { nsExtendOutput2Entry 2 } Cannot adopt OID in UCD-SNMP-MIB: laIndex ::= { laEntry 1 } Cannot adopt OID in UCD-SNMP-MIB: laNames ::= { laEntry 2 } Cannot adopt OID in UCD-SNMP-MIB: laLoad ::= { laEntry 3 } Cannot adopt OID in UCD-SNMP-MIB: laConfig ::= { laEntry 4 } Cannot adopt OID in UCD-SNMP-MIB: laLoadInt ::= { laEntry 5 } Cannot adopt OID in UCD-SNMP-MIB: laLoadFloat ::= { laEntry 6 } Cannot adopt OID in UCD-SNMP-MIB: laErrorFlag ::= { laEntry 100 } Cannot adopt OID in UCD-SNMP-MIB: laErrMessage ::= { laEntry 101 } Cannot adopt OID in NET-SNMP-AGENT-MIB: nsNotifyRestart ::= { netSnmpNotifications 3 } Cannot adopt OID in NET-SNMP-AGENT-MIB: nsNotifyShutdown ::= { netSnmpNotifications 2 } Cannot adopt OID in NET-SNMP-AGENT-MIB: nsNotifyStart ::= { netSnmpNotifications 1 } There a literally hundreds of these. If snmp doesn't even like the distro-included MIBs, what chance to I have of getting my own used? (I get the same form of error with my own MIB, on a different machine, which is why I set up a clean install.) Do other distros have this issue? Is there something obvious that I am overlooking here? Thanks, Chris.

  • SQL Cluster on Hyper V Failover Cluster

    - by Chris W
    We have a VM running SQL Server on a 6 node cluster of blades. The VM's data files are stored a SAN attached using a direct iSCSI connection. As this SQL server will be running a number of important databases we're debating whether we should be clustering the SQL Server or will the fact that the VM is running in the cluster itself sufficient to give us high availability. I'm used to running SQL clusters when dealing with physical servers but I'm a bit sketchy on what is best practice when all the servers are just VMs sat on Hyper V. If a blade running the VM fails I presume the VM will be started up on another load. I'm guessing the only benefit that adding a SQL cluster to the setup will give us it that the recovery time after a failure will be a little quicker? Are there any other benefits?

  • AD DS or AD LDS

    - by rajeevrautela
    Hi all, Greeetings !!! I need a suggestion about having AD DS or AD LDS for my infrastructure. So lets begin, Ex. I am having a website which as of now do not have any log in facility for the visitors, now we are developing a new application so that the visitors can create account on the website. the best example you can think of is of any telecom service provider, they have their webiste and now is creating a login facility for it's customers so the users can create an account and can subscribe for ebill sort of facilties. Hope the situation is clear now. for this particular application, i intend to have a web server, an application server, a DB server, one SMTP server and one AD server(for authentication of users and for saving the profiles also). My question here starts on AD front, here do i need AD DS or AD LDS here, what i need from AD is 1) provide user authentication, 2) provide role based access. this is my query. hope i'll get the answer very soon.

  • javaws not found

    - by Hunt
    I have a server which has centos installed in it. Recently I have installed jdk 1.6 into it. When I try to run java command from shell it's working perfectly fine. Java is stored into /usr/java/jdk1.6.0_25 and path is set to /usr/bin/ when I type which java. When I tried running javaws (which comes with the jdk 1.6 only) it is showing me following error: Java Web Start splash screen process exiting ...

  • What does it mean when ARP shows <incomplete> on eth1

    - by Geoff Dalgas
    We have been using HAProxy along with heartbeat from the Linux-HA project. We are using two linux instances to provide a failover. Each server has with their own public IP and a single IP which is shared between the two using a virtual interface (eth1:1) at IP: 69.59.196.211 The virtual interface (eth1:1) IP 69.59.196.211 is configured as the gateway for the windows servers behind them and we use ip_forwarding to route traffic. We are experiencing an occasional network outage on one of our windows servers behind our linux gateways. HAProxy will detect the server is offline which we can verify by remoting to the failed server and attempting to ping the gateway: Pinging 69.59.196.211 with 32 bytes of data: Reply from 69.59.196.220: Destination host unreachable. Running arp -a on this failed server shows that there is no entry for the gateway address (69.59.196.211): Interface: 69.59.196.220 --- 0xa Internet Address Physical Address Type 69.59.196.161 00-26-88-63-c7-80 dynamic 69.59.196.210 00-15-5d-0a-3e-0e dynamic 69.59.196.212 00-21-5e-4d-45-c9 dynamic 69.59.196.213 00-15-5d-00-b2-0d dynamic 69.59.196.215 00-21-5e-4d-61-1a dynamic 69.59.196.217 00-21-5e-4d-2c-e8 dynamic 69.59.196.219 00-21-5e-4d-38-e5 dynamic 69.59.196.221 00-15-5d-00-b2-0d dynamic 69.59.196.222 00-15-5d-0a-3e-09 dynamic 69.59.196.223 ff-ff-ff-ff-ff-ff static 224.0.0.22 01-00-5e-00-00-16 static 224.0.0.252 01-00-5e-00-00-fc static 225.0.0.1 01-00-5e-00-00-01 static On our linux gateway instances arp -a shows: peak-colo-196-220.peak.org (69.59.196.220) at <incomplete> on eth1 stackoverflow.com (69.59.196.212) at 00:21:5e:4d:45:c9 [ether] on eth1 peak-colo-196-215.peak.org (69.59.196.215) at 00:21:5e:4d:61:1a [ether] on eth1 peak-colo-196-219.peak.org (69.59.196.219) at 00:21:5e:4d:38:e5 [ether] on eth1 peak-colo-196-222.peak.org (69.59.196.222) at 00:15:5d:0a:3e:09 [ether] on eth1 peak-colo-196-209.peak.org (69.59.196.209) at 00:26:88:63:c7:80 [ether] on eth1 peak-colo-196-217.peak.org (69.59.196.217) at 00:21:5e:4d:2c:e8 [ether] on eth1 Why would arp occasionally set the entry for this failed server as <incomplete>? Should we be defining our arp entries statically? I've always left arp alone since it works 99% of the time, but in this one instance it appears to be failing. Are there any additional troubleshooting steps we can take help resolve this issue? THINGS WE HAVE TRIED I added a static arp entry for testing on one of the linux gateways which still didn't help. root@haproxy2:~# arp -a peak-colo-196-215.peak.org (69.59.196.215) at 00:21:5e:4d:61:1a [ether] on eth1 peak-colo-196-221.peak.org (69.59.196.221) at 00:15:5d:00:b2:0d [ether] on eth1 stackoverflow.com (69.59.196.212) at 00:21:5e:4d:45:c9 [ether] on eth1 peak-colo-196-219.peak.org (69.59.196.219) at 00:21:5e:4d:38:e5 [ether] on eth1 peak-colo-196-209.peak.org (69.59.196.209) at 00:26:88:63:c7:80 [ether] on eth1 peak-colo-196-217.peak.org (69.59.196.217) at 00:21:5e:4d:2c:e8 [ether] on eth1 peak-colo-196-220.peak.org (69.59.196.220) at 00:21:5e:4d:30:8d [ether] PERM on eth1 root@haproxy2:~# arp -i eth1 -s 69.59.196.220 00:21:5e:4d:30:8d root@haproxy2:~# ping 69.59.196.220 PING 69.59.196.220 (69.59.196.220) 56(84) bytes of data. --- 69.59.196.220 ping statistics --- 7 packets transmitted, 0 received, 100% packet loss, time 6006ms Rebooting the windows web server solves this issue temporarily with no other changes to the network but our experience shows this issue will come back. Swapping network cards and switches I noticed the link light on the port of the switch for the failed windows server was running at 100Mb instead of 1Gb on the failed interface. I moved the cable to several other open ports and the link indicated 100Mb for each port that I tried. I also swapped the cable with the same result. I tried changing the properties of the network card in windows and the server locked up and required a hard reset after clicking apply. This windows server has two physical network interfaces so I have swapped the cables and network settings on the two interfaces to see if the problem follows the interface. If the public interface goes down again we will know that it is not an issue with the network card. (We also tried another switch we have on hand, no change) Changing network hardware driver versions We've had the same problem with the latest Broadcom driver, as well as the built-in driver that ships in Windows Server 2008 R2. Replacing network cables As a last ditch effort we remembered another change that occurred was the replacement of all of the patch cords between our servers / switch. We had purchased two sets, one green of lengths 1ft - 3ft for the private interfaces and another set of red cables for the public interfaces. We swapped out all of the public interface patch cables with a different brand and ran our servers without issue for a full week ... aaaaaand then the problem recurred. Disable checksum offload, remove TProxy We also tried disabling TCP/IP checksum offload in the driver, no change. We're now pulling out TProxy and moving to a more traditional x-forwarded-for network arrangement without any fancy IP address rewriting. We'll see if that helps.

  • HP SmartArray P400 has slow read and write speed

    - by Tadas D.
    I have desktop in which I installed HP SmartArray P400 controller with two HP DF0146B8052 hard drives. I made RAID0 logical volume from them, but I am getting 20MB/s write speed and ~140-120MB/s read speed. Also there is quite low scatter for benchmark results (I am getting quite nice line) and it looks like controller is "capping" my speeds. I tried reseting controllers configuration and I haven't found any settings in HP ACU (Array Configuration Utility) to help me. I am using Windows 7 Ultimate and M4A78 board Does anyone have ideas what could be wrong? Also I am attaching diagnostic results.

  • Httpd + Expect Script Fail (no more ptys) if httpd is not run through cli

    - by Apostolis
    I have a CentOS virtual server through Vmware. The server runs an httpd daemon which serves an php page with a form. The users complete the form, and by clicking submit the php page calls an expect scripts. If i run the httpd throught the default init.d script i get a "no more ptys" error, but if i run httpd through root terminal the script runs without problems. How can i make the httpd run the expect scripts without having to run the httpd daemon by hand.

    Hi I'm trying to get RDP services running with Windows 2008 R2. I'm at a WINXP SP3 client that was modified to run RDP with NLA. When I start the client connect to the local DC and get an authentification error (Code 0x507). I've already done the following: • Server Setup to run as a standalone local "DC" to provide Terminal services to a single application. Remote Desktop Session Host CAL License is running & operational, RD Gateway Manager w/ Local Server RAP & CAP running NLA & operational etc..... Server has NLA & temporary use of port 3389 (which is directly connected to and accessible from the internet (I am planning to change the port to 443, but want to get the current system running first). • XP Client(s): RDP-Version on win xp clients is 6.1 If had SP2, then added SP3 and edited the registry settings to allow NLA, by: Click Start, click Run, type regedit, and then press ENTER. In the navigation pane, locate and then click the following registry subkey: HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Control\Lsa In the details pane, right-click Security Packages, and then click Modify. In the Value data box, type tspkg. Leave any data that is specific to other SSPs, and then click OK.

  • Server 2008 RAID5 resynching

    - by benpage
    I built a W2K8 R2 server last weekend, and built a R5 array using Disk Management, 5x 1TB drives. For the next 60 hours the status said 'Resynching (X%)' as it built the array. during this time i did read and write to the drive (slowly) and once the rebuild was complete speeds were quite fast. I was copying over some data from a USB hard drive overnight, and the machine crashed (looking in the error i believe it was the driver for the usb drive) and so the RAID5 went back to resynching, since the machine was not shut down properly. The issue is, it's been about 48 hours since that started and I'm happy to say it will take roughly 60 hours again to resynch, however.. all this time in Disk Management, the status has only said 'Resynching', not 'Resynching (X%)'. The hard drive light is going nuts, and read/writes are slow again, so I'm assuming it is actually resynching. The question is - is that a correct assumption? and why is disk management not telling me what %age it's done? Is this normal behaviour for a not-properly-shut-down r5 array?

  • How to set up Mod_WSGI for Python on Ubuntu

    - by AutomatedTester
    Hi, I am trying to setup MOD_WSGI on my Ubuntu box.

  • CentOS6 system-config-packages missing?

    - by Ben Swinburne
    I've just installed CentOS 6 with gnome but the graphical package manager no longer appears to be there. I've tried installing both system-config-packages and pirut using Yum but neither finds anything. I've checked the package lists and it doesn't appear to be there. I looked at this list which doesn't imply that there is an RPM at all for CentOS6. The package manager is available during the install, however. I don't recall seeing an option to include it in the installer but that's not to say it isn't there- I just don't fancy re installing the OS just to check if it's there. Has the package been superseded by another package by a different name, or has it been removed completely? If so, are there any other graphical package managers I can try? I generally use Yum but as I'm experimenting with CentOS6 at the moment it's just nice to have a quick graphical representation of the packages available.
