• hosts file seems to be ignored

  - by z4y4ts

  I have almost fresh Ubuntu desktop box. OS was installed two weeks ago and updated from karmic repositories. Last week I had no problems with DNS. But this week something had changed. I'm not sure what and when, and not sure whether I changed any configs. So now I have some really weird situation. According to logs name resolving should work normally. /etc/hosts 127.0.0.1 localhost test 127.0.1.1 desktop /etc/host.conf order hosts,bind multi on /etc/resolv.conf # Generated by NetworkManager search search servers obtained via DHCP nameserver 192.168.0.3 /etc/nsswitch.conf passwd: compat group: compat shadow: compat hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis But if fact it is not. user@test ~ping test PING localhost (127.0.0.1) 56(84) bytes of data. [skip] Pinging is ok. user@test ~host test test.mydomain.com has address xx.xxx.161.201 But pure I suspect that NetworkManager might cause this misbehavior, but don't know where to start to check it. Any thoughts, suggestions?

• Excel not properly recalculating values

  - by gms8994

  I have an excel sheet with values in it (this sheet is generated by a custom perl script, but I don't think that's where the problem lies). In it, I have a formula: =sum(indirect(concatenate(address(6,column()),":",address(17,column())))) The purpose of this formula is to give me the SUM() of the cells in the current column, between rows 6 and 17. In Gnumeric Spreadsheet, as soon as I open the file, this works. But in Excel (both 2003 and 2007), opening the file gives #VALUE! errors in the fields with this formula, stating that the INDIRECT call with the values $B$6:$B$17 will result in an error. Here's the kink in the issue. If I edit the field (via F2), and make no changes, and hit enter, the values update. Also, it seems, if I save the file as .xlsx (Excel 2007 format), the values update upon opening. Unfortunately, I'm not sure that creating an xlsx is a possibility with the modules that I'm using, and many of our clients probably wouldn't be able to use it anyway. Any suggestions? Editing 200+ files every month for each client isn't going to be feasible, so if there's something I'm missing, please let me know.

• CNAME rule being ignored

  - by Ben

  On a server with Plesk installed I have added a CNAME rule pointing from one of the sites subdomains to an external website. I have checked the named configuration for that domain name and it shows the CNAME however the sub domain just points to the default server page and ignores the CNAME rule. Named has been restarted and I've also run the rvmng reconfigure-vhost command. I edited another server to test this, on cPanel, and it works fine. The conf file for the domain: ; *** Ts file is automatically generated by Plesk *** $TTL 86400 @ IN SOA ns.example.com. cf.example1.com. ( 1292946742 ; Serial 10800 ; Refresh 3600 ; Retry 604800 ; Expire 10800 ) ; Minimum example.com. IN NS ns.example.com. ns.example.com. IN A xx.xxx.xxx.xx example.com. IN A xx.xxx.xxx.xx webmail.example.com. IN A xx.xxx.xxx.xx mail.example.com. IN A xx.xxx.xxx.xx beta.example.com. IN A xx.xxx.xxx.xx ftp.example.com. IN CNAME example.com. www.example.com. IN CNAME example.com. login.example.com. IN CNAME socialize.gigya.com. example.com. IN MX 10 webmail.example.com. You can see the CNAME rule in the file but it just gets ignored? Thanks in advance for any help.

• Widespread misinterpretation of DNS rules in resolving wildcards

  - by Dominic Sayers

  [EDITED to add: This problem has gone away on its own. I believe Cloudflare's name resolution may have been to blame. See my own answer below] Here is a snippet of my zone file *.example.com. 300 IN CNAME proxy.herokuapp.com. foo.example.com. 300 IN A 111.111.111.111 If I dig @8.8.8.8 foo.example.com I get the answer I expect: ;; ANSWER SECTION: foo.example.com. 30 IN A 111.111.111.111 The same is true of all other public DNS servers I've tried. However, when I try to set up a check with Pingdom to a URL on foo.example.com it instead sends the traffic to my Heroku app referenced by the *.example.com RR. The same is true of checks set up on New Relic, Errplane and traffic generated by the Heroku app itself. So on the one side, all public DNS servers interpret the zone file one way. Yet four service providers all interpret it a different way, one that differs to the standard suggested by RFC 4592. My question is: are these reputable, mature service providers all wrong? Or is it little me?

• RemoteApp shows no certificate available but RD Session host finds it fine

  - by Scott Chamberlain

  I am trying to set up remote app for a internal domain. I have a Root CA that is trusted my all of the end computers, that cert has signed a wildcard cert I am trying to use for the server. I added the pfx of the wildcard cert to the local machine personal store. From there I can use it fine for signing the RD Session Host session. However when I try to set up the signature for Remote App the certificate does not show up. What do I need to do to get my certificate to be available for for use? UPDATE: The Certificate was generated through the following commands: makecert -pe -n "CN=*.vw.local" -a sha1 -sky signature -ic VetWebCA.cer -iv VetWebCA.pvk -sv VetWebComputerWildcard.pvk VetWebComputerWildcard.cer pvk2pfx -pvk VetWebComputerWildcard.pvk -spc VetWebComputerWildcard.cer -pfx VetWebComputerWildcard.pfx The resultant pfx was added to the machine local store via mmc. Oddly, going in to Powershell if I add the -CodeSigningCert flag to find the wildcard certificate it is excluded from the serch results for Get-Childitem in my Cert:\Local Machine\My path, but if I don't include it it is there.

• What do I need to do to set my computer as Default Gateway?

  - by Vaibhav

  We are trying to put together a box with dual LAN cards (let's say Outer and Inner), where the Inner LAN card is supposed to act as a default gateway on the network it is connected to. This box is running Ubuntu. The basic purpose for this box is to take messages generated on the inner network, do some work with them and forward them out the Outer LAN card to a server. The inner network is completely isolated with simply a regular switch connecting the Inner LAN Card with two other boxes. These other boxes either throw out multi-cast messages (which the Inner LAN Card is listening to), or send out unicast messages meant for the server which is not on this inner network. So, we need the Inner LAN Card to act as a default gateway, where these unicast messages will then be sent, and the code on the dual-LAN Card box can then intercept and forward these messages to the server. Question: 1. How do we setup the LAN Card to be default gateway (does it need some configuration on Ubuntu)? 2. Once we have this setup, is it a simple matter of listening to the interface to intercept the incoming messages? Any help (pointers in the right direction) is appreciated. Thanks.

• ASP.NET sending email through exchange problem

  - by Solmead

  I have an exchange 2010 server running on Windows 2008 R2, I also have a remote webserver running Windows 2003 with multiple sites on it (all asp.net mvc 2 sites). I setup a Transport in exchange and all the websites on my remote web server can send email no problem to anyone in the exchange server and to any external domain. Now for my problem. I am having issues with that webserver, so I moved one of the websites to run on my exchange server, it runs well (low hit website) except that email doesn't work from that site. I tried changing the Transport in exchange to add the IP address of the local machine and the 127.0.0.1 addresses and it still isn't sending any email. Any ideas on how to get this working? The remote websites can still send email no problem, the version of the site that I had to move on the remote server can still email, but on the exchange server for that website email does not send. I would guess it is a Transport issue, since it is running on the same server a firewall shouldn't be the issue. I changed the smtp setting in web.config to localhost, and now I do receive email to my account on the exchange server, but I do not receive any emails on outside addresses. To add more description, this is a custom developed asp.net mvc 2 website. And no errors were being generated in the code when sending the email in either case.

• Win2k8R2 / IIS 7.5 - users getting 503 response, no 503 error reported in logs

  - by merk

  I've got 2 web servers with mirrored content. There's a load balancer sitting in front of them. Starting yesterday we've been getting people complaining about 503 errors. i can't find any 503 errors in the IIS log file. However the server host is saying these errors are due to .Net errors in our website which are causing the app pool to recycle. They pointed out several errors in the windows application event log which look like this: Log Name: Application Source: ASP.NET 4.0.30319.0 Date: 3/31/2012 8:35:37 PM Event ID: 1309 Task Category: Web Event Level: Warning Keywords: Classic User: N/A Computer: 6251.local Description: Event code: 3005 Event message: An unhandled exception has occurred. Event time: 3/31/2012 8:35:37 PM Event time (UTC): 4/1/2012 1:35:37 AM Event ID: e7a580c7b38545cca3416a8595408f24 Event sequence: 97 Event occurrence: 1 Event detail code: 0 Application information: Application domain: /LM/W3SVC/2/ROOT-1-129777167518960645 Trust level: Full Application Virtual Path: / Application Path: C:\inetpub\wwwroot\mywebsite\ Machine name: 6252 Process information: Process ID: 20000 Process name: w3wp.exe Account name: IIS APPPOOL\MyAppPool In particular they are saying that the account name under Process Information indicates that the app pool is recycling. They said if the app pool were not recycle, the accountname would instead be the folder where the website files are located. I checked the app pool settings - it's set to recycle every 29 hours. And the rapid fail protection is set to the default of 5 failures in 5 minutes. But i have not seen 5 failures in the event log in that short of a time span. Can anyone help me confirm if the 503 responses are indeed being generated by the app pools recycling? Or are these errors coming from somewhere else? My guess at the time was their load balancer was the one actually returning the 503 error. But that was just a guess.

• Configuration Help for Sendmail Required

  - by Vinayak Mahadevan

  Hi I need some help with respect to sendmail configuration. The basic problem is that I have some employees working from other places and they need access to their mail. So what I have done right now is whatever mails which are meant for them which are generated from within the company and collected by my internal mail server is bounced to an external mail server from where the employees access it. This is done through a email id on a different domain. This was working fine till I restricted the external mailing access for certain users using rulesets in sendmail.cf. Once I had put that in place only people who had external mailing rights could send mails to people outside the office. What I would like to know is that is there anyway where I can expose sendmail on two different ips and thereby configure everybody's email id to point to the same internal mail server using 2 different ips. one ip when inside the company and one ip outside the company. Is it possible that I have one static ip configured for both internal access and external access or is there any otherway it can be done with sendmail. Can anybody help me Sorry for the long post Regards Vinayak

• Squid SSL transparent proxy - SSL_connect:error in SSLv2/v3 read server hello A

  - by larryzhao

  I am trying to setup a SSL proxy for one of my internal servers to visit https://www.googleapis.com using Squid, to make my Rails application on that server to reach googleapis.com via the proxy. I am new to this, so my approach is to setup a SSL transparent proxy with Squid. I build Squid 3.3 on Ubuntu 12.04, generated a pair of ssl key and crt, and configure squid like this: http_port 443 transparent cert=/home/larry/ssl/server.csr key=/home/larry/ssl/server.key And leaves almost all other configurations default. The authorization of the dir that holds key/crt is drwxrwxr-x 2 proxy proxy 4096 Oct 17 15:45 ssl Back on my dev laptop, I put <proxy-server-ip> www.googleapis.com in my /etc/hosts to make the call goes to my proxy server. But when I try it in my rails application, I got: SSL_connect returned=1 errno=0 state=SSLv2/v3 read server hello A: unknown protocol And I also tried with openssl in cli: openssl s_client -state -nbio -connect www.googleapis.com:443 2>&1 | grep "^SSL" SSL_connect:before/connect initialization SSL_connect:SSLv2/v3 write client hello A SSL_connect:error in SSLv2/v3 read server hello A SSL_connect:error in SSLv2/v3 read server hello A Where did I do wrong?

• Using our own certificate authority for business email encryption

  - by LumenAlbum

  I've read the available similar questions on serverfault but I haven't quite found a definite answer to the security aspect of it - hence here's my question: I'm administrator of an office working with tax data and we want to start using certificate-based eMail encryption with our clients. Considering the prices for issued certificates by VeriSign & Co I was wondering if we couldn't issue the necessary certificates with a certificate authority of our own. I realize that they do not offer the trust hierarchy that commercial certificates do but I don't see why we would need that. Most of our clients have small businesses and only 20% of them even exchange data with us via email. So if we were to issue certificates for those 20% and our employees, that would enable us to use encrypted emails. Of course they would have to trust our certificate authority and thus once receive our public root certificate. But if we would hand them out to them (or install it) personally, they'd know that it really is our certificate. Is thery a huge security risk that I am missing here? As long as nobody has access to our certificate authority server nobody should be able to interfere with security, right? And the client certificates would be generated and handed out by us, as well... Please advise me if I am making an error in judgement here and thank you in advance.

• Installing mod_pagespeed (Apache module) on CentOS

  - by Sid B

  I have a CentOS (5.7 Final) system on which I already have Apache (2.2.3) installed. I have installed mod_pagespeed by following the instructions on: http://code.google.com/speed/page-speed/download.html and got the following while installing: # rpm -U mod-pagespeed-*.rpm warning: mod-pagespeed-beta_current_x86_64.rpm: Header V4 DSA signature: NOKEY, key ID 7fac5991 [ OK ] atd: [ OK ] It does appear to be installed properly: # apachectl -t -D DUMP_MODULES Loaded Modules: ... pagespeed_module (shared) And I've made the following changes in /etc/httpd/conf.d/pagespeed.conf Added: ModPagespeedEnableFilters collapse_whitespace,elide_attributes ModPagespeedEnableFilters combine_css,rewrite_css,move_css_to_head,inline_css ModPagespeedEnableFilters rewrite_javascript,inline_javascript ModPagespeedEnableFilters rewrite_images,insert_img_dimensions ModPagespeedEnableFilters extend_cache ModPagespeedEnableFilters remove_quotes,remove_comments ModPagespeedEnableFilters add_instrumentation Commented out the following lines in mod_pagespeed_statistics <Location /mod_pagespeed_statistics> **# Order allow,deny** # You may insert other "Allow from" lines to add hosts you want to # allow to look at generated statistics.

• SQL 2008 SP1 crashing almost daily

  - by matijake

  Hey, almost every day our new DB crashes. It is virtual server residing on same hardware as 5 other servers, two of them beeing identical MS SQL2008sp1 and two Oracle 11g's so I can pretty much rule out hardware issues. Server has dedicated local LUN, 4vCPU and 8GB memory with 2GB windows swap file. It runs 4 instances. Primary instance is limited to 5GB memory and paralelism set to 4 running on MS SQL 2008 SP1 @ Windows Server 2008 Enterprise R2 x64. Only that primary instance is crashing. After it crashes nothing can connect to it, it's even impossible to shut it down through service manager. What I found in logs is: ***Stack Dump being sent to C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\LOG\SQLDump0081.txt SqlDumpExceptionHandler: Process 4788 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server i s terminating this process.     Whole log can be seen at: http://kabl.org/files/SQLDump0081.txt second crash log made second later at: http://kabl.org/files/SQLDump0082.txt I have analyzed mini crashdump with Microsoft tools, but no promising results. If it can help, here it is: http://kabl.org/files/SQLDump0081.mdmp Any ideas are greatly welcome, since it is becoming quite a pain in the ass to restart server almost every day :) Regrads, -Matija

• dns configuration error in plesk

  - by Karthik Malla

  I purchased a domain www.softmail.me at Godaddy.com and tried it DNS and getting lots of errors and finally change my nameservers to my server DNS i.e. NS101.VPSLAND.COM and NS202.VPSLAND.COM and created a domain in my plesk panel (Marked DNS & Mail required). After adding my domain to my plesk panel of my server I opened DNS records of that domain and found DNS records are automatically generated to my needs as following 65.75.241.26 / 24 PTR softmail.me. ftp.softmail.me.

• Saving a file in a CSV type in Excel always removes the BOM

  - by rickp

  I've been trying to find a reasonable solution/explanation (unsuccessfully) to find out why Excel defaults to removing the BOM when saving a file to the CSV type. Please forgive me if you find this a duplicate of this question. This handles reading CSV files with non-ASCII encoding, but it doesn't cover saving the file back out (which is where the biggest issue lies). Here is my current situation (which I'm going to gather is common among localized software dealing with Unicode characters and a CSV format): We export data to a CSV format using UTF-16LE, ensuring the BOM is set (0xFFFE). We validate after the file is generated with a Hex editor to ensure it was set correctly. Open the file in Excel (for this example we're exporting Japanese characters) and witness that Excel handles loading the file with the correct encoding. Attempts to save this file will prompt you with a warning message indicating that the file may contain features that may not be compatible with Unicode encoding, but asks if you'd like to save anyway. If you select the Save As dialog, it will immediately ask you to save the file as "Unicode Text" rather than CSV. If you select the "CSV" extension and save the file it removes the BOM (obviously along with all the Japanese characters). Why would this happen? Is there a solution to this problem, or is this a known 'bug'/limitation of Excel? Additionally (as a side issue) it appears that Excel, when loading UTF-16LE encoded CSV files, only uses TAB delimiters. Again, is this another known 'bug'/limitation of Excel?

• How to embed Arial in PDF when PDF has Helvetica?

  - by Brooks Moses

  So, I've got a PDF file that's generated by a program that uses the Base 14 fonts, so that it contains "Helvetica" and "Times Roman". When I look at that in my copy of Acrobat 7.0 on Windows (for example), it shows these with Arial and Times New Roman. I'm fine with that. The issue is that I'd like to publish this PDF file on lulu.com, and they want all fonts embedded. Including the Base 14. I don't have a copy of Helvetica, so what seems the natural thing to do is substitute Arial for Helvetica and embed Arial. How can I do that? I tried using the Print feature in Acrobat (note: this is the full version, not Reader) to print to a PDF file using Adobe's "Print to PDF" printer driver, and selected the "Embed All Fonts" option in the print settings. This worked for the fonts that I had actual copies of, but instead of "printing" Arial for Helvetica -- which it would do if printing to a real printer -- it leaves all the Helvetica as Helvetica and doesn't embed it. Any suggestions for alternate ways to do this? What I really want is just a copy of my PDF file with ALL fonts embedded, and I'm quite happy if doing that means making one of the usual substitutions for the "Helvetica" that's in it. I'd be happiest if I can do that within Acrobat or other software that I have (pdftex, maybe?), but I'm willing to install another free utility if I need to.

• Dos/ Flood Lag even though Port not Saturated

  - by Asad Moeen

  My GameServers had been under some UDP Floods due to which they generated outputs to the attacker which gave the GameServers some huge lags. Thanks to friends at ServerFault that upon different kind of testing, I was able to successfully block the attack. My question is actually something else but it is important to know how the GameServers reacted to the attack and if the machine kept stable or not: 300kb/s Input would cause GameServer to generate 2mb/s Output. So as the Input Rate kept increasing, output rate would reach so high that it would no longer be possible for the GameServer to control it and hence it would give a huge Lag until the attack is stopped. Usually the game server starts to lag when it sends out something greater than 5mb/s and under that is controllable. Theoretically, I was able to receive a 60mb/s output from my GameServer on inputting 10mb/s. Its just the way the GameServer works if not protected. Now on some of my machines, only the GameServer under attack lagged and although the server was generating 60mb/s output, rest of the gameservers on other ports would run fine without lags on the same machine. But there was another machine which also runs on a 100 MBPS Network port, even 1 mbps input ( and ZERO output because attack is blocked ) even on an unused port would give a constant yellow line ( on the Lag-o-Meter ) to all the clients on all GameServers indicating lag because that line is actually blue under normal conditions. It would remain the same even on 50mbps or 900mbps input. I tried contacting the host about it because I believe its the way their Network is bridged, but they can't help me about it. Anyone else knowing about such issues because if 900mbps input does not Saturate the port, how can 1mbps input lag the servers although port is not saturated and enough bandwidth is available?

• pdftotext not outputting hebrew characters

  - by Ofri Raviv

  I'm using Xpdf's pdftotext to get the text out of some hebrew pdf files on Ubuntu. On my local machine this worked fine. I then tried to do it on another machine and the hebrew characters don't show up in the text file. I verified that I have the language package (see below why I think so). Where else can I look for the problem? >> tail -2 /etc/xpdf/xpdfrc include /etc/xpdf/includes >> cat /etc/xpdf/includes # This file was automatically generated by /usr/sbin/update-xpdfrc. # Instead, add or remove files in /etc/xpdf/ then run # /usr/sbin/update-xpdfrc to regenerate this file. include /etc/xpdf/xpdfrc-latin2 include /etc/xpdf/xpdfrc-thai include /etc/xpdf/xpdfrc-greek include /etc/xpdf/xpdfrc-turkish include /etc/xpdf/xpdfrc-arabic include /etc/xpdf/xpdfrc-hebrew include /etc/xpdf/xpdfrc-cyrillic >> cat /etc/xpdf/xpdfrc-hebrew #----- begin Hebrew support package (2003-feb-16) unicodeMap ISO-8859-8 /usr/share/xpdf/hebrew/ISO-8859-8.unicodeMap unicodeMap Windows-1255 /usr/share/xpdf/hebrew/Windows-1255.unicodeMap #----- end Hebrew support package >> ls /usr/share/xpdf/hebrew/ ISO-8859-8.unicodeMap Windows-1255.unicodeMap

• Why Ubuntu could treat hosts file so strange?

  - by z4y4ts

  I have almost fresh Ubuntu desktop box. OS was installed two weeks ago and updated from karmic repositories. Last week I had no problems with DNS. But this week something had changed. I'm not sure what and when, and not sure whether I changed any configs. So now I have some really weird situation. According to logs name resolving should work normally. /etc/hosts 127.0.0.1 localhost test 127.0.1.1 desktop /etc/host.conf order hosts,bind multi on /etc/resolv.conf # Generated by NetworkManager search search servers obtained via DHCP nameserver 192.168.0.3 /etc/nsswitch.conf passwd: compat group: compat shadow: compat hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis But if fact it is not. user@test ~ping test PING localhost (127.0.0.1) 56(84) bytes of data. [skip] Pinging is ok. user@test ~host test test.myviacube.com has address xx.xxx.161.201 But pure I suspect that NetworkManager might cause this misbehavior, but don't know where to start to check it. Any thoughts, suggestions?

• How to make ssh connection between servers using public-key authentication

  - by Rafael

  I am setting up a continuos integration(CI) server and a test web server. I would like that CI server would access web server with public key authentication. In the web server I have created an user and generated the keys sudo useradd -d /var/www/user -m user sudo passwd user sudo su user ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/var/www/user/.ssh/id_rsa): Created directory '/var/www/user/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /var/www/user/.ssh/id_rsa. Your public key has been saved in /var/www/user/.ssh/id_rsa.pub. However othe side, CI server copies the key to the host but still asks password ssh-copy-id -i ~/.ssh/id_rsa.pub user@webserver-address user@webserver-address's password: Now try logging into the machine, with "ssh 'user@webserver-address'", and check in: .ssh/authorized_keys to make sure we haven't added extra keys that you weren't expecting. I checked on the web server and the CI server public key has been copied to web server authorized_keys but when I connect, It asks password. ssh 'user@webserver-address' user@webserver-address's password: If I try use root user rather than my created user (both users are with copied public keys). It connects with the public key ssh 'root@webserver-address' Welcome to Ubuntu 11.04 (GNU/Linux 2.6.18-274.7.1.el5.028stab095.1 x86_64) * Documentation: https://help.ubuntu.com/ Last login: Wed Apr 11 10:21:13 2012 from ******* root@webserver-address:~#

  I've been trying to login in the pyload through the web api, but wget is not saving the cookies and I don't understand why. I'm using the following command: wget --delete-after --keep-session-cookies --save-cookies=my_cookies.txt --post-data="username=USERNAME&password=PASSWORD" http://localhost:8000/api/login But the content of my_cookies.txt is: # HTTP cookie file. # Generated by Wget on 2012-06-23 22:31:33. # Edit at your own risk.
