  • Logging data with scribe

    - by lukatmyshu
    None of the scribe examples I've seen actually mention the best way to take logs/logfiles and send them to scribe. I could configure a logrotate script that has a postrotate section that "cats" the rotated file to scribe (but then I get minutes latency at best). The other option is to keep a "tail -f= | my_scribe_sender" and hope that the process never gets killed. However then you really can't guarantee that you're not missing/duplicating data.

  • Specified argument was out of the range of valid values. Parameter name: utcDate

    - by Rob
    Our logs show hundreds of these errors after our deployment if users are on the site. Anyone know what this means and how to fix it? Notes: We are using msdeploy, IIS 6 I recently noticed that our web server's time is about 10 minutes behind the real time, I think that may have something to do with it. If I log into our site, seems like any file that depends on a WebResource or ScriptResource type file doesn't look right. Seems to fix itself after an IIS reset

  • Need to integrate phpFox and Wordpress so that there is a single login.

    - by Jason
    phpFox should take care of user login management, add user and edit user. But would like to automatically create a corresponding Wordpress account when user signs up for phpFox. And when user logs into phpFox user is auto logged into Wordpress so user doesn't really even realize Wordpress login or user account exists. What would be the best way to do this? Apps will be on the same server so could make native calls or use curl.

  • How do i make form data not disappear after hitting refresh?

    - by acidzombie24
    I went to test my page on another browser. On google chrome i can fill out a form, hit back and forward and still have the data there. Now i need to refresh the page so certain data is correct (such as session id if the cookie expires or user logs out before submitting). I refresh and lose all data. Is there some option i can set so all data is kept?

  • Roaming user profile issues on Server 2008

    - by Alicia White
    I thought I cleared a user's profile from 2008, but it keeps coming back. So, I was looking for the best way to clear a roaming profile in Server 2008, but I have been unable to find anything. But, I did see the post here: http://serverfault.com/questions/18724/user-profile-keeps-loading-temp-profile I wanted to add a comment to that post, but it was closed as not being related to sysadmin. But, I think it IS related because I dealt with precisely this same problem on our Wndows 2008 terminal server. Here was the issue: we have a user who was getting an "unable to load your roaming profile" type of error at logon in Windows 2008. Looking at the server, we could see her temp profile listed in the profile list while she was loggged (listed as a "temporary" and not a "roaming" profile). While she was logged on, a folder called C:\Users\Temp.DOMAIN existed in the users folder, but that disappeared as soon as she logged out. When this thing happened in 2003, we would clear the contents of the roaming profile folder & delete the temp folder in C:\Documents and Settings. The thing is, 2008 behaves a bit differently. Server 2008 created a new roaming profile folder in the roaming profile folder share: \SERVER\ProfileShare\UserName.V2 The local profile disappears from the profile list in System Properties, so there is no profile to clear Also the local profile folder, C:\Users\Temp.DOMAIN doesn't stay on the server when the user logs out, so we can't delete that as we would normally do when this sort of thing happens in Windows 2003 Despite all of this, every time the user logs back on, the frickin' Temp profile always comes back. One of my team-mates, who is much more experienced with 2008, said I should check the registry for the user's profile in this key (the users are listed by SID): HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\ProfileList I saw the user's SID listed there, but it ended in .BAK. I checked several other servers where she is having the same profile errors: in all cases, her SID ended with .BAK. For example (xxx replacing the LONG SID): HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-21-xxxxx-xxxx.bak On the server she was logged on to, there were two keys for her profile in the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-21-xxxxx-xxxx and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-21-xxxxx-xxxx.bak So, here is how I cleared up the issue. I had the user log off. I deleted the apparently bad profiles ending in .BAK from the ProfileList key on each server where it appeared. I made sure her roaming profile folder was empty I made sure that all the TEMP profile folders were gone The user logged back on: no more profile errors! Anyway, I wanted to make a comment on that closed question, but I didn't see any way to re-open the question so I could add it. But, I also would like to know if this is the best practice to clear out a bad roaming profile for Server 2008? I'm having a hard time finding any instructions on line on how best to do this, but this method I used seemed to work. I'd like to find some documentation to give to our Level 1 support staff so they will know how to clear user profiles on 2008 since this seems to be more involved that clearing user profiles in server 2003. Thanks, Alicia

  • Delaying NIS & NFS startup till after network interface is fully ready on Fedora 17

By the looks of these logs the ypbind service is starting up at 12:57:12 but the network interface isn't coming up till 12:57:15. My guess is that this is causing ypbind to time out when trying to connect. As a knock-on effect the NIS failure is causing problems with NFS which is no longer able to map UIDs properly. This problem doesn't seem to be fixed by actually starting ypbind etc. so I've had to set all my NFS shares to noauto. I have tried manually adding NETWORKDELAY and NETWORKWAIT in /etc/sysconfig/network and also running systemctl enable NetworkManager-wait-online.service as I've seen suggested in some places, but neither of these have had any effect. It is relatively easy to fix manually by restarting ypbind & mounting NFS shares after the network has started up, but it's less than ideal to have to do this every time the server has been rebooted. Does anyone know of an easy (and preferably hack-free) way of delaying the ypbind startup till after the network interface is fully ready?

  • SQL Server (2012 Enterprise) Browser service failing

    - by Watki02
    SQL Server (2012 Enterprise) Browser service failing I have a problem as described below: I have an instance of SQL Server 2012 Enterprise (thanks to MSDN) for local development on my PC. I try to start SQL server Browser Service from SQL Server Configuration Manager and it takes a long time to fail, then fails with: The request failed or the service did not respond in a timely fashion. Consult the event log or other applicable error logs for details. I checked event logs and found these errors in this order (all within the same 1-second time frame): The SQL Server Browser service port is unavailable for listening, or invalid. The SQL Server Browser service was unable to establish SQL instance and connectivity discovery. The SQL Server Browser is enabling SQL instance and connectivity discovery support. The SQL Server Browser service was unable to establish Analysis Services discovery. The SQL Server Browser service has started. The SQL Server Browser service has shutdown. I checked firewall rules and both port 1433 (TCP) and 1434 (UDP) are wide open, just as well - the programs and service binary had been "allowed through windows firewall". I started the "Analysis Services" service by hand and it works fine. Browser still won't start. Some History: Installed SQL 2008 R2 express advanced Installed SQL2012 Express advanced Uninstalled SQL 2008 R2 express advanced Installed 2012 SSDT and lots of features with Express install Installed a unique instance of SQL 2012 Enterprise with all features Uninstalled SSDT and reinstalled SSDT with Enterprise (solved a different problem) Uninstalled SQL 2012 Express Uninstalled SQL 2012 Enterprise Removed anything with "SQL" in the name from Control panel "Programs and features" Installed SQL 2012 Enterprise without Analysis services (This is where I noticed SQL Browser service was failing to start even on the install) Added the feature of Analysis Services (and everything else) via the installer (Browser continued to fail to start on the install) ======================== Other interesting facts: opening a command window with administrator and trying to run sqlbrowser.exe manually yielded: Microsoft Windows [Version 6.1.7601] Copyright (c) 2009 Microsoft Corporation.

  • Trying to use Digest Authentication for Folder Protection

    - by Jon Hazlett
    StackOverflow users suggested I try my question here. I'm using Server 2008 EE and IIS 7. I've got a site that I've migrated over from XP Pro using IIS 5. On the old system, I was using IIS Password to use simple .htaccess files to control a couple of folders that I didn't want to be publicly viewable. Now that I'm running a full-blown DC with a more powerful version of IIS, I decided it'd be a good idea to start using something slightly more sophisticated. After doing my research and trying to keep things as cheap as possible with a touch of extra security, I decided that Digest Authentication would be the best way to go. My issue is this: With Anon access disabled and Digest enabled, I am never prompted for credentials. when on the server, viewing domain[dot]com/example will simply show my 401.htm page without prompting me for credentials. when on a different network/computer, viewing domain[dot]com/example again shows my 401.htm without prompting for credentials. At the site level I only have Anon enabled. Every subfolder, unless I want it protected, has just Anon enabled. Only the folders I want protected have Anon disabled and Digest enabled. I have tried editing the bindings to see if that would spark any kind of change... www.domain.com, domain.com, and localhost have all been tried. There was never a change in behavior at any permutation (aside from the page not being found when I un-bound localhost to the site). I might have screwed up when I deleted the default site from IIS. I didn't think I'd actually need it for anything, but some of what I have read online is telling me otherwise now. As for Digest settings, I have it pointed to local.domain.com, which is the name assigned to my AD Domain. I'm guessing that's right, but honestly have no clue about what a realm actually is. Would it matter that I have an A record for local.domain.com pointing to my IP address? I had problems initially with an absolute link for 401.htm pages, but have since resolved that. Instead of D:\HTTP\401.htm I've used /401.htm and all is well. I used to get error 500's because it couldn't find the custom 401.htm file, but now it loads just fine. As for some data, I was getting entries like this from access logs: 2009-07-10 17:34:12 10.0.0.10 GET /example/ - 80 - [workip] Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+.NET+CLR+1.1.4322;+.NET+CLR+2.0.50727;+InfoPath.2) 401 2 5 132 But after correcting my 401.htm links now get logs like this: 2009-07-10 18:56:25 10.0.0.10 GET /example - 80 - [workip] Mozilla/5.0+(Windows;+U;+Windows+NT+5.1;+en-US;+rv:1.9.0.11)+Gecko/2009060215+Firefox/3.0.11 200 0 0 146 I don't know if that means anything or not. I still don't get any credential challenges, regardless of where I try to sign in from ( my workstation, my server, my cellphone even ). The only thing that's seemed to work is viewing localhost and I donno what could be preventing authentication from finding it's way out of the server. Thanks for any help! Jon

  • Sharepoint AD imported users are becomming sporadically corrupted, causing us to have to create a new account

    - by TrevJen
    Sharepoint 2007 MOSS with AD imported users. All servers are 2008. ***UPDATE More details in testing. This Sharepoint is in an AD Child domain (clients.mycompany.local), which is sub to the root of the AD tree (mycompany.local). The user is in the parent tree (as are half of the other functional users. I have elevated the user rights to Domain. In looking at the logs, it seems that the Sharepoint server is trying to authenticate them by querying the DC for the clients domain (which is the way it normally works and still works for all existing identically configured users). I think if I could force it to authenticate up to the top domain DC then it would be ok?? I have around 50 users, over the past 2 months, I have had a handful of the users suddenly unable to login to Sharepoint. When they login, they either get a blank screen or they are repropmted. These users are using accounts that have been used for many months, sometimes the problem originates with a password change. In all cases, the users account works on every other Active Directory authenticated resource (domain, exchange, LDAP). In the most recent case, last night I was forced deleted a user ("John smith") because of corruption. The orifinal account name was jsmith. I deleted him from active directory, then deleted him from the profile list in Sharepoint Shared Services. I could not find a way to delete him from the Sharepoint user list, but I reran the import after recreating his account (renamed it too just to be sure to "smithj"). At first, this did not wor, the user could still access all other resources but Sharepoint. then, some 30 minutes later it inexplicably started working. This morning, the user changed passwords, which immediatly broke the login on Sharepoint again.

  • Nginx + PHP-FPM = "Random" 502 Bad Gateway

    - by david
    I am running Nginx and proxying php requests via FastCGI to PHP-FPM for processing. I will randomly receive 502 Bad Gateway error pages - I can reproduce this issue by clicking around my PHP websites very rapidly/refreshing a page for a minute or two. When I get the 502 error page all I have to do is refresh the browser and the page refreshes properly. Here is my setup: nginx/0.7.64 PHP 5.3.2 (fpm-fcgi) (built: Apr 1 2010 06:42:04) Ubuntu 9.10 (Latest 2.6 Paravirt) I compiled PHP-FPM using this ./configure directive ./configure --enable-fpm --sysconfdir=/etc/php5/conf.d --with-config-file-path=/etc/php5/conf.d/php.ini --with-zlib --with-openssl --enable-zip --enable-exif --enable-ftp --enable-mbstring --enable-mbregex --enable-soap --enable-sockets --disable-cgi --with-curl --with-curlwrappers --with-gd --with-mcrypt --enable-memcache --with-mhash --with-jpeg-dir=/usr/local/lib --with-mysql=/usr/bin/mysql --with-mysqli=/usr/bin/mysql_config --enable-pdo --with-pdo-mysql=/usr/bin/mysql --with-pdo-sqlite --with-pspell --with-snmp --with-sqlite --with-tidy --with-xmlrpc --with-xsl My php-fpm.conf looks like this (the relevant parts): ... <value name="pm"> <value name="max_children">3</value> ... <value name="request_terminate_timeout">60s</value> <value name="request_slowlog_timeout">30s</value> <value name="slowlog">/var/log/php-fpm.log.slow</value> <value name="rlimit_files">1024</value> <value name="rlimit_core">0</value> <value name="chroot"></value> <value name="chdir"></value> <value name="catch_workers_output">yes</value> <value name="max_requests">500</value> ... I've tried increasing the max_children to 10 and it makes no difference. I've also tried setting it to 'dynamic' and setting max_children to 50, and start_server to '5' without any difference. I have tried using both 1 and 5 nginx worker processes. My fastcgi_params conf looks like: fastcgi_connect_timeout 60; fastcgi_send_timeout 180; fastcgi_read_timeout 180; fastcgi_buffer_size 128k; fastcgi_buffers 4 256k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; fastcgi_intercept_errors on; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; fastcgi_param REDIRECT_STATUS 200; Nginx logs the error as: [error] 3947#0: *10530 connect() failed (111: Connection refused) while connecting to upstream, client: 68.40.xxx.xxx, server: www.domain.com, request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "www.domain.com" PHP-FPM logs the follow at the time of the error: [NOTICE] pid 17161, fpm_unix_init_main(), line 255: getrlimit(nofile): max:1024, cur:1024 [NOTICE] pid 17161, fpm_event_init_main(), line 93: libevent: using epoll [NOTICE] pid 17161, fpm_init(), line 50: fpm is running, pid 17161 [DEBUG] pid 17161, fpm_children_make(), line 403: [pool default] child 17162 started [DEBUG] pid 17161, fpm_children_make(), line 403: [pool default] child 17163 started [DEBUG] pid 17161, fpm_children_make(), line 403: [pool default] child 17164 started [NOTICE] pid 17161, fpm_event_loop(), line 111: ready to handle connections My CPU usage maxes out around 10-15% when I recreate the issue. My Free mem (free -m) is 130MB I had this intermittent 502 Bad Gateway issue when in was using php5-cgi to service my php requests as well. Does anyone know how to fix this?

  • Varnish POST problem "9 FetchError c backend write error: 11" for application/x-www-form-urlencoded content

    - by ompap
    Cutting a longish story short, we have managed to get a more precise error out of Varnishlog. Varnishlog tells us that we are sending a 31 TxRequest - POST 31 TxHeader - Content-Type: application/x-www-form-urlencoded but we are getting 9 FetchError c backend write error: 11 31 BackendClose - [backend name] 9 VCL_call c error 9 VCL_return c deliver 9 Length c 488 9 VCL_call c deliver 9 VCL_return c deliver 9 TxProtocol c HTTP/1.1 9 TxStatus c 503 We still do not know what this is exactly, but apparently Content-Type: application/x-www-form-urlencoded is not getting through as it should. Help still needed, please! Original message below. The title was "Varnish not letting Joomla users to log in - 503 guru meditation error", but I changed it to get more attention to the problem and not to the symptoms. Hello, We have a production site for a local newspaper which is currently behind an Apache reverse proxy, basicly the site on one server and the other being reserved as a reverse proxy only (well, there is more but that has no relevance here). Apache as a reverse proxy works, but could be faster. We want to change the reverse proxy to use Varnish instead of Apache on an Ubuntu 10.4 Server. The Varnish is version 2.10 installed directly from Ubuntu repos. Ubuntu 10.4 uses PHP 5.3.2. For anonymous surfers the site works wonderfully with Varnish. So far we can get very good speed out of Varnish, we just have a few problems with logging in or out. The big one is, that the users cannot log in: they get a Varnish 503 error page every time. The logs do not reveal the cause. It feels as if the request would never leave Varnish. So we are merely guessing - not a strong starting point. We have gone through what has been suggested on various plces on the web. We have increased the timeouts to backend xxx { .host = "xxx.xx"; .port = "http"; .connect_timeout = 60s; .first_byte_timeout = 60s; .between_bytes_timeout = 60s; } but we seem to get the 503 guru error page much faster than that, as in approx. 5 seconds. We have increased the Varnish headers size to 128 in daemon. In vcl_recv we have if (req.http.Authenticate || req.http.Authorization) { return(pass); } and in vcl_fetch ## auhtentication handling if (req.http.Authenticate || req.http.Authorization) { return(pass); } We do not strip cookies. We have tried to make sure that error pages are not cached. As said above, we cannot see anything in the backend Apache logs, apparently it never gets asked for Joomla user authentication. Varnish does not seem to get much mentioning with connection to Joomla. (We cannot dump Joomla, that selection has been done and we just have to live with what we have been given) Has anyone a working Varnish - Joomla combination? Thanks for reading. Please help. We need some hints - desperately. Any suggestions? ompap

  • Apache mod_jk Setting for Tomcat - workers.properties

    - by sissonb
    I am trying to direct files with .jsp extensions to tomcat. Otherwise I want apache to serve the file directly (no tomcat). Currently I have a test.jsp which is supposed to create an HTML page with the current date in the body. Instead when I go to that .jsp I see the JK Status Manager. The mod_jk.logs only show, init_jk::mod_jk.c (3365): mod_jk/1.2.35 initialized. I have tomcat and apache setup on my server. Apache runs on 80 and tomcat runs on 8080. localhost:8080 show the tomcat welcome page. I downloaded tomcat-connectors-1.2.35-windows-i386-httpd-2.2.x and copied the mod_jk.so to C:\apache\modules. Then I added LoadModule jk_module modules/mod_jk.so to my httpd.conf. I restart apache and the module loads just fine. Next I downloaded the mod_jk source to get the workers.properties file. I copy workers.properties to C:\apache\confg. Then I added this user, workers.tomcat_home="C:/Program Files/Apache Software Foundation/Tomcat 7.0" workers.java_home="C:/Program Files/Java/jdk1.7.0_03" worker.list=ajp13 worker.ajp13.port=8080 worker.ajp13.host=localhost worker.ajp13.type=ajp13 worker.ajp13.socket_timeout=10 When I try to use the ajp13 user in my httpd.conf I get the following error in my mod_jk.log, [Wed Mar 28 13:08:51 2012] [2196:4100] [info] ajp_connection_tcp_get_message::jk_ajp_common.c (1258): (ajp13) can't receive the response header message from tomcat, network problems or tomcat (127.0.0.1:8080) is down (errno=60) [Wed Mar 28 13:08:51 2012] [2196:4100] [error] ajp_get_reply::jk_ajp_common.c (2117): (ajp13) Tomcat is down or refused connection.

  • Issue in setting up VPN connection (IKEv1) using android (ICS vpn client) with Strongswan 4.5.0 server

    - by Kushagra Bhatnagar
    I am facing issues in setting up VPN connection(IKEv1) using android (ICS vpn client) and Strongswan 4.5.0 server. Below is the set up: Strongswan server is running on ubuntu linux machine which is connected to some wifi hotspot. Using the steps in this guide link, I generated CA, server and client certificate. Once certificates are generated, following (clientCert.p12 and caCert.pem) are sent to mobile via mail and installed on android device. Below are the ip addresses assigned to various interfaces Linux server wlan0 interface ip where server is running: 192.168.43.212, android device eth0 interface ip address: 192.168.43.62; Android device is also attached with the same wifi hotspot. On the Android device, I uses IPsec Xauth RSA option for setting up VPN authentication configuration. I am using the following ipsec.conf configuration: # basic configuration config setup plutodebug=all # crlcheckinterval=600 # strictcrlpolicy=yes # cachecrls=yes nat_traversal=yes # charonstart=yes plutostart=yes # Add connections here. # Sample VPN connections conn ios1 keyexchange=ikev1 authby=xauthrsasig xauth=server left=%defaultroute leftsubnet=0.0.0.0/0 leftfirewall=yes leftcert=serverCert.pem right=192.168.43.62 rightsubnet=10.0.0.0/24 rightsourceip=10.0.0.2 rightcert=clientCert.pem pfs=no auto=add      With the above configurations when I enable VPN on android device, VPN connection is not successful and it gets timed out in Authentication phase. I ran wireshark on both the android device and strongswan server, from the tcpdump below are the observations. Initially Identity Protection (Main mode) exchanges happens between device and server and all are successful. After all successful Identity Protection (Main mode) exchanges server is sending Transaction (Config mode) to device. In reply android device is sending Informational message instead of Transaction (Config mode) message. Further server is keep on sending Transaction (Config mode) message and device is again sending Identity Protection (Main mode) messages. Finally timeout happens and connection fails. I also capture Strongswan server logs and below are the snippets from the server logs which also verifies the same(described above).

  • Random Slow Response

    - by ARehman
    We have an ASP.NET MVC 1.0 application running on Windows Server 2008 – Standard (32 –bit), Dual Core Xeon (3.0 GHz), 2 G.B R.A.M. Most of the times application renders response in 3-4 seconds, but sometimes users get very late response and delay is up to 40 seconds or more than a minute. It happens in following way: User browsed a page, idle for 5, 10 or 15 minutes, tried to browse same page or some other. Now, there is a chance that he will see late response whereas the app pool is still up and running. This can happen with any arbitrary page. We have tried followings/observations. Moved the application to stand alone web server App Pool idle shutdown time is 60 minutes. There are no abrupt shut downs/restarts. CPU or memory doesn’t spike. No delays in SQL queries. Modified App Pool setting to run in classic-mode. It didn’t help. Plugged-in custom module to log all those requests which took more than 5 seconds to complete. It didn’t pick any request of interest. Enabled ‘Failed Request Tracing’ to log all those requests which take 20 or more seconds to complete. It didn’t log anything. Event Viewer, HTTPER log, W3SVC logs or WAS logs don’t indicate anything. HTTPERR only has ‘_ _ Timer_ConnectionIdle _ _’ entries. There is not much traffic to server. This can happen also if only two users are active. Next we captured TCP/IP terrific on both a user and server end with Wireshark and below are details in brief of this slowness: Browser sends a request for ~/User/Home/ (GET Request) by setting up a receiving end point using port 'wlbs(port-2504)'. I'm not sure if this could be a problem in some way that browser didn't hand-shake with the server first and assumed that last connection is still open, whereas, I browsed the same page 4 minutes ago and didn't perform any activity with site after that. If I see the HTTPERR log, it indicates that it has ‘_ _ Timer_ConnectionIdle _ _ _’ entry for my last activity with server. Browser (I was using Chrome) waits for any response from the server, doesn’t find any then starts retransmitting the same request using same end point after incrementing wait intervals, e.g. after 8, 18, 29, 40, 62, and 92 seconds. All these GET requests were received by server as well. But, server didn’t send any packet to client. Browser didn't see any response on the end point it set up in point 1, it opened a new end point 'optiwave-lm (port-2524)', did a hand shake with the server and transmitted the same request again. Server received, processed it, and returned successful response. What happened to earlier 6-7 requests? Whether they were passed on to HTTP.SYS or not? Why Failed Request Tracing not logged anything, we didn't find any clue yet. Server served the same page successfully just 4 minutes ago. Looking forward for more suggestions/solutions. -- Thanks

  • Facing issues in setting up VPN connection(IKEv1) using iphone (Defult Cisco VPN client) and Strongswan 4.5.0 server

    - by Kushagra Bhatnagar
    I am facing issues in setting up VPN connection(IKEv1) using iPhone (Defult Cisco VPN client) and Strongswan 4.5.0 server. The Strongswan server is running on Ubuntu Linux, which is connected to some wifi hotspot. This is the guide which was used. I generated CA, server and client certificate, with the only difference mentioned below. “While generating server certificate, as per link CN=vpn.strongswan.org instead of this I changed CN name to CN=192.168.43.212.” Once certificates are generated, following (clientCert.p12 and caCert.pem) are sent to mobile via mail and installed on iphone. After installation I notice that certificates are considered as trusted also. Below are the ip addresses assigned to various interfaces Linux server wlan0 interface ip where server is running: 192.168.43.212 Iphone eth0 interface ip address: 192.168.43.72. iphone is also attached with the same wifi hotspot. Below is the snapshot of client configurations. Description Strong swan Server 192.168.43.212 Account ipsecvpn Password ***** Use certificate ON Certificate client The above username and password are in sync with the ipsec.secrets file. I am using the following ipsec.conf configuration: # basic configuration config setup plutodebug=all # crlcheckinterval=600 # strictcrlpolicy=yes # cachecrls=yes nat_traversal=yes # charonstart=yes plutostart=yes # Add connections here. # Sample VPN connections conn ios1 keyexchange=ikev1 authby=xauthrsasig xauth=server left=%defaultroute leftsubnet=0.0.0.0/0 leftfirewall=yes leftcert=serverCert.pem right=192.168.43.72 rightsubnet=10.0.0.0/24 rightsourceip=10.0.0.2 rightcert=clientCert.pem pfs=no auto=add With the above configurations when I enable VPN on iphone, it says Could not able to verify server certificate. I ran Wireshark on a Linux server and observe that initially some ISAKMP message exchanges happens between client and server, which are successful but before authorization, client is sending some informational message and soon after this client is showing error as popup Could not able to verify server certificate. Capture logs on Strongswan server and in server logs below errors are observed: From auth.log Apr 25 20:16:08 Linux pluto[4025]: | ISAKMP version: ISAKMP Version 1.0 Apr 25 20:16:08 Linux pluto[4025]: | exchange type: ISAKMP_XCHG_INFO Apr 25 20:16:08 Linux pluto[4025]: | flags: ISAKMP_FLAG_ENCRYPTION Apr 25 20:16:08 Linux pluto[4025]: | message ID: 9d 1a ea 4d Apr 25 20:16:08 Linux pluto[4025]: | length: 76 Apr 25 20:16:08 Linux pluto[4025]: | ICOOKIE: f6 b7 06 b2 b1 84 5b 93 Apr 25 20:16:08 Linux pluto[4025]: | RCOOKIE: 86 92 a0 c2 a6 2f ac be Apr 25 20:16:08 Linux pluto[4025]: | peer: c0 a8 2b 48 Apr 25 20:16:08 Linux pluto[4025]: | state hash entry 8 Apr 25 20:16:08 Linux pluto[4025]: | state object not found Apr 25 20:16:08 Linux pluto[4025]: **packet from 192.168.43.72:500: Informational Exchange is for an unknown (expired?)

  • simple and reliable centralized logging inside Amazon VPC

    - by Nakedible
    I need to set up centralized logging for a set of servers (10-20) in an Amazon VPC. The logging should be as to not lose any log messages in case any single server goes offline - or in the case that an entire availability zone goes offline. It should also tolerate packet loss and other normal network conditions without losing or duplicating messages. It should store the messages durably, at the minimum on two different EBS volumes in two availability zones, but S3 is a good place as well. It should also be realtime so that the messages arrive within seconds of their generation to two different availability zones. I also need to sync logfiles not generated via syslog, so a syslog-only centralized logging solution would not fulfill all the needs, although I guess that limitation could be worked around. I have already reviewed a few solutions, and I will list them here: Flume to Flume to S3: I could set up two logservers as Flume hosts which would store log messages either locally or in S3, and configure all the servers with Flume to send all messages to both servers, using the end-to-end reliability options. That way the loss of a single server shouldn't cause lost messages and all messages would arrive in two availability zones in realtime. However, there would need to be some way to join the logs of the two servers, deduplicating all the messages delivered to both. This could be done by adding a unique id on the sending side to each message and then write some manual deduplication runs on the logfiles. I haven't found an easy solution to the duplication problem. Logstash to Logstash to ElasticSearch: I could install Logstash on the servers and have them deliver to a central server via AMQP, with the durability options turned on. However, for this to work I would need to use some of the clustering capable AMQP implementations, or fan out the deliver just as in the Flume case. AMQP seems to be a yet another moving part with several implementations and no real guidance on what works best this sort of setup. And I'm not entirely convinced that I could get actual end-to-end durability from logstash to elasticsearch, assuming crashing servers in between. The fan-out solutions run in to the deduplication problem again. The best solution that would seem to handle all the cases, would be Beetle, which seems to provide high availability and deduplication via a redis store. However, I haven't seen any guidance on how to set this up with Logstash and Redis is one more moving part again for something that shouldn't be terribly difficult. Logstash to ElasticSearch: I could run Logstash on all the servers, have all the filtering and processing rules in the servers themselves and just have them log directly to a removet ElasticSearch server. I think this should bring me reliable logging and I can use the ElasticSearch clustering features to share the database transparently. However, I am not sure if the setup actually survives Logstash restarts and intermittent network problems without duplicating messages in a failover case or similar. But this approach sounds pretty promising. rsync: I could just rsync all the relevant log files to two different servers. The reliability aspect should be perfect here, as the files should be identical to the source files after a sync is done. However, doing an rsync several times per second doesn't sound fun. Also, I need the logs to be untamperable after they have been sent, so the rsyncs would need to be in append-only mode. And log rotations mess things up unless I'm careful. rsyslog with RELP: I could set up rsyslog to send messages to two remote hosts via RELP and have a local queue to store the messages. There is the deduplication problem again, and RELP itself might also duplicate some messages. However, this would only handle the things that log via syslog. None of these solutions seem terribly good, and they have many unknowns still, so I am asking for more information here from people who have set up centralized reliable logging as to what are the best tools to achieve that goal.
