Starting multiple Chrome full screen instances on multiple monitors from (batch) script

- by Bob Groeneveld

My goal is to show different web content full screen on multiple monitors automatically after booting from a single computer. The browser I would like to use is Chrome. If Chrome does not support this and Firefox does that would be fine. The OS I would prefer is Windows, if it turns out that Linux is possible that would be fine. On Windows it is possible to set the position of the Chrome browser window (--window-position=) and make Chrome start in full screen mode (--kiosk). Using these options combined you can start Chrome full screen on any of the desktops/screens that you have connected to your computer. I have managed to get this working. However, if I then try to do the same thing a second time to have Chrome full screen on a second screen the second Chrome window will open over the first window, no matter the coordinates I use for the --window-position parameter. I have tried using Chrome profiles and copying the Chrome directory and starting the second chrome.exe. All these things result in the same behaviour.

Server not accepting uploads

- by Tatu Ulmanen

I'm having a strange problem with my VPS: I can download files from it, I can use PuTTy to connect to it and all behaves normally. But sometimes, when I try to upload a file to the server or save a file via SFTP, the connection inexplicably fails. I am using jEdit to edit files remotely via SFTP. When it works, it works fine. When it doesn't, I get an error message: Cannot save: java.io.IOException: inputstream is closed Cannot save: java.io.IOException: 4: I can see that a temporary save file (#file.php#save#) is created on the server with a filesize of 0. So the connection works, but when it comes to sending the actual data, something fails. The same thing with WinSCP, but the error is different: Copying file fatally failed. Copying files to remote side failed. And I can always browse the server with PuTTy without a problem. I see nothing abnormal in any log files. Auth.log shows this when I try to save: sshd[32638]: Accepted password for - from - port 62272 ssh2 sshd[32638]: pam_unix(sshd:session): session opened for user - by (uid=0) sshd[32640]: subsystem request for sftp sshd[32638]: pam_unix(sshd:session): session closed for user - When I wait for a while (say, an hour), everything works fine again. It can't be a temporary ban, as I am still allowed to connect to the server, right? I know this may not be enough info to solve the problem, but I am grateful for any clues or bits of information that might help me. What are the possible causes for this kind of behaviour, what log files can I check for clues etc.. I'm running out of ideas!

What causes PHP pages to consistently download instead of running normally

- by Jonathan

Hi, I'm running a Ubuntu Server on a VM, to test out different web forum solutions. I have set up a ~/public_html/ to be accessible with the apache2 web server, and that works fine. However when I go to a .php file on a browser (using my VM's ip-address/~username/phpfile.php) it does not display it as it should. Instead it offers to save to file/asks what program to open it with. Interestingly though that dialog box does recognise that it is a php file. I have the following version of php installed on the system: PHP 5.3.2-1ubuntu4.5 with Suhosin-Patch (cli) (built: Sep 17 2010 13:49:46) Copyright (c) 1997-2009 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies And the following server: Server version: Apache/2.2.14 (Ubuntu) Server built: Nov 18 2010 21:19:09 If anyone knows what might be causing this/potential solutions it would make me very happy :) EDIT: Turns out files this behaviour was only apparent on files in the ~/public_html/ directory. All php files in /var/www/ work fine. Prizes go to whoever can explain why? :D (And by prizes I just mean a well done, no actual prizes I'm afraid.)

Very Slow DSL (ethernet) speed [New Interesting Update]

- by Abhijit

Very IMPORTANT and INTERESTING UPDATE: Due to some reason I just thought to do a complete new setup and this time I decided to again have openSUSE plus ubuntu. So I first reinstall lubuntu and then I installed OpenSUSE 12.2 (64 bit). Now, my DSL speed is working very normal and fine on opensuse. So this is very scary. Is it possible for any operating system to manipulate my NIC so that it will work fine only on that operating system and not on another os? Regarding positive thinking and not being paranoid, what is it that makes ONLY suse to get my NIC to work at normal speed but ubuntu can not do it? Not even fedora? Not even linux mint? What all these OS are lacking that enables suse to work great? == ORIGINAL QUESTION == I 'was' on opensuse 12.2 when my dsl speed was normal. Yesterday I switched from opensuse to ubuntu 12.04 and speed decreased. It came to range of 7-10-13-20-25-kbps. Then I switch to linux mint, and then to fedora. Still slow speed. When I was in ubuntu I disabled ipv6 but still no luck. Now I am in fedora but this time with DIFFERENT ISP. And still I am getting very slow sped. So my guess is this is nothing to do with os. What can be wrong? Is this problem of NIC? Does NIC speed decreases over time? Does NIC life ends over time as with keyboard or mouse? Help please All the os I used are 64 bit and my laptop is Compaq Presario A965Tu Intel Centrino DUal Core. Interesting thing to notice is I get normal speed while downloading torrent inside torrent client softwares. This slow speed issue applied to download from any web browser or installing software using terminal.

Unusable network, packet losses between router and NIC

- by KáGé

I have this setup: Gigabyte P35-DS3P motherboard Asus NX1101 PCI network card (the one on the motherboard got fried a few years ago by a power surge) Asus RT-N16 router Windows 7 x64 I think the other specs are irrelevant here, but I'll post them if you say so. Until a week ago everything was fine, but then my network became unusable: websites start loading but timeout before anything would come through (true for the web interface of the router as well), I can't reach the computer from my notebook and Windows' ping utility measures a ~50% packet loss between the computer and the router. Pinging localhost is good. The router works completely fine when wired to my notebook. I also tested different ports on the router, different cables, different router and connecting directly to the modem, but it's still the same. Sometimes it works for a few minutes right after turning on the machine, but then it becomes crap again, but mostly it's useless from the start. I've tried updating the firmware on the router, updating the driver for the network card (after which I started getting BSoDs in every 15 minutes), reinstalling Windows, swapping to Fedora 15 but none of them changed anything. Does this mean that the network card is dying, or could it be something else? If it's the card, what model do you recommend as a replacement? (Could be PCI or PCI-Ex x1) Thanks for your help.

Losing internet connection after few minutes (5-10 maybe)

- by Korchkidu

I took a computer that was not updated for months. Internet was working just fine so basically, I updated zonealarm, avast and installed all windows updates and especially SP3. After that, when I reboot, Internet works fine but after few minutes, Firefox says that the connection was reset. IE does not work either. However, my connection is still up and running as I can make a ping on www.google.com for example. Here are the solutions I tried with no success so far: 1) Uninstalling SP3; 2) Uninstalling IE8 and IE7; 3) Manually setting DNS and IPs; 4) Removed proxy settings from Firefox and IE; 5) Restarting DNS and DHCP related services; 6) Reset TCP/IP with netsh int ip reset c:\resetlog.txt; 7) Updated my ehternet card driver; 8) Restarted, tweaked all the connections in any directions and any configuration possible I believe; 9) Disabled Zone Alarm and Avast; Also, update kb981793 always fails on install. Please, help me as I spent two days already on this and I cannot find any solution. If I cannot fix this problem tomorrow, I will have to format-reinstall everything. Thanks for any help. Regards.

Convert MPG w/ AC3 audio to something else - on a Mac

- by anonymous coward

I'm helping with a small volunteer media team, and they have several .mpg videos that don't appear to have sound when played in QuickTime, iTunes, Real Player, etc, on the local Mac machine. I was able to hear audio after transferring one of the movies to a Windows machine that had VLC media player on it. Through VLC I was able to discover that the audio stream is a52 / AC3 format. We use Autodesk Cleaner in our normal workflow of converting the format of our videos to FLV, but for some reason it's unable to convert this particular batch of videos (well, the video converts fine, but with no audio). Obviously, it seems that there's a codec issue here, but I'm not sure how to correct it. (I'm not extremely familiar with Macs, and/or Autodesk Cleaner). I've seen the Perian codec pack, but I'm not sure that having the codecs on the system will enable Cleaner to convert these videos (particularly the audio stream, since the video converts fine). Is there something obvious that I'm overlooking, or will we have to use something else for this particular batch of videos? If so, what?

Host couldn't be reached by domain name, only by IP: Apache's fault?

- by MaxArt

I have this Windows Server 2003 R2 32 bit machine running Apache 2.4.2 with OpenSSL 1.0.1c and PHP 5.4.5 via mod_fcgid 2.3.7. This config worked just fine for some hours, but then the site couldn't be reached with its domain name, say www.example.com, but it could be still reached by its IP address. In particular, while https://www.example.com/ yielded a connection error, http://123.1.2.3/ worked just fine. Yes, first https then http. Error and access logs were clean, i.e. they showed no signs of problems. Just the usual messages, that were interrupted while the site couldn't be reached. After some investigation, a simple restart of Apache solved the problem. Unfortunately, I didn't have the chance to test if https://123.1.2.3/ worked as well, or if http://www.example.com/ was still redirected to https as usual. So, has anyone have any idea of what happened? Before I get tired of Apache and ditch it in favor of Nginx? Edit: Some log informations. The last line of sslerror.log is from 90 minutes before the problem occurred, so I guess it's not important. ssl_request.log shows nothing interesting, too: these are the last two lines before the problem: [28/Aug/2012:17:47:54 +0200] x.x.x.x TLSv1.1 ECDHE-RSA-AES256-SHA "GET /login HTTP/1.1" 1183 [28/Aug/2012:17:47:45 +0200] y.y.y.y TLSv1 ECDHE-RSA-AES256-SHA "POST /upf HTTP/1.1" 73 The previous lines are all the same and don't seem interesting, except 4 lines like these 30-40 seconds before the problem: [28/Aug/2012:17:47:14 +0200] z.z.z.z TLSv1 ECDHE-RSA-AES256-SHA "-" - These are the corrisponding lines from sslaccess.log: z.z.z.z - - [28/Aug/2012:17:47:14 +0200] "-" 408 - ... x.x.x.x - - [28/Aug/2012:17:47:54 +0200] "GET /login HTTP/1.1" 200 1183 y.y.y.y - - [28/Aug/2012:17:47:45 +0200] "POST /upf HTTP/1.1" 200 73

Windows 7 can't find Ubuntu computer by hostname

- by endolith

I got a new Windows 7 machine, and was using VNC, SSH etc to connect to my Ubuntu machine, and it worked fine previously connecting to the Ubuntu computer's hostname. Now it doesn't work if I use the machine's hostname, but it does if I use the local IP or DynDNS name. I can also access it from my Android phone using the local hostname over SSH. If I try to connect with SSH to the hostname, it says "Host does not exist". VNC says "Failed to get server address". NX says "no address associated with name", and I don't see it in Windows' "Network" folder. I've rebooted everything. I've turned off Windows firewall. It was working fine a few days ago, but now it's not. How do I figure out what's blocking it? Aha: It probably has something to do with Samba. I reset the Samba configuration the other day, and apparently this can affect it. http://ubuntu-virginia.ubuntuforums.org/showthread.php?t=1558925 I tried commenting out "encrypt passwords = No" as described there, but it still doesn't work.

nginx giving 404 when accessing php from alias directory

- by code90

I am trying to migrate from apache to nginx. The php sites that I am hosting need to access a shared library which turns out to be an alias directory. Below is the configuration I came up with. html files work fine, but php files giving 404. I have read through and tried most (if not all) of the answers to the similar questions with no any success. Any hint on what might be causing the issue in my case? location /wtlib/ { alias /var/www/shared/wtlib_4/; index index.php; } location ~ /wtlib/.*\.php$ { alias /var/www/shared/wtlib_4/; try_files $uri =404; if ($fastcgi_script_name ~ /wtlib(/.*\.php)$) { set $valid_fastcgi_script_name $1; } fastcgi_pass 127.0.0.1:9013; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/shared/wtlib_4$valid_fastcgi_script_name; fastcgi_param REDIRECT_STATUS 200; include /etc/nginx/fastcgi_params; } Thanks all ! Update: Following seems to be working fine: location /wtlib/ { alias /usr/share/php/wtlib_4/; location ~* .*\.php$ { try_files $uri @php_wtlib; } location ~* \.(html|htm|js|css|png|jpg|jpeg|gif|ico|pdf|zip|rar|air)$ { expires 7d; access_log off; } } location @php_wtlib { if ($fastcgi_script_name ~ /wtlib(/.*\.php)$) { set $valid_fastcgi_script_name $1; } fastcgi_pass $byr_pass; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /usr/share/php/wtlib_4$valid_fastcgi_script_name; fastcgi_param REDIRECT_STATUS 200; include /etc/nginx/fastcgi_params; }

vSphere Promiscuous mode only receiving packets one way from network switch

- by steve.lippert

We have two network switches, a POE switch (SwitchA) to power our phones / users computers and a non-POE switch (SwitchB for the rest network.) Each switch is setup to do port mirroring to support our VoIP recording system. SwitchA does port mirroring on specific ports if we need to record a user. SwitchB mirrors one port to monitor our work at home users (Internet comes in from managed router, to switch, back out to our firewall.) These two port mirroring setups feed into one vmware vSphere 4.1 server, it has four total physical cards. The other two NICs feed into an unmanaged switch for connecting to the rest of the network. Once into the vSphere server all network ports go into a vSwitch, and then one of the servers (Windows 2008 R2) sniffs them out and does its thing. Everything is working fine and dandy from SwitchB. But on SwitchA we only receive one side of the VoIP packets (going out to the phone, nothing coming in from the phone). Troubleshooting steps I have taken so far: I hooked up my laptop to the monitor port on SwitchB and I see both sides of the packets. I swapped which network interface is plugged into the monitor port on SwitchA. Because everything feeds into one vSwitch / vNetwork and both sides of the conversation arrive just fine from SwitchB I believe everything is configured correctly on the vSphere server/guest. What could be causing one way packets to arrive on my guest machine from only one interface, but not the other? Could a bad cable be causing the problems from SwitchB?

setting the PATH for Git (not for me)

- by Iain

Hi, I'm running OSX 10.6.5 with Git 1.7.1 I have git installed in a non-standard location (though that really should be the standard on a mac;-) in /Library/Frameworks/Git.framework. My own PATH is set fine, git works fine, until... I set up a pre-commit hook with a Ruby script: $ git commit -m "added some Yard documentation" .git/hooks/pre-commit: line 1: #!/usr/bin/env: No such file or directory The pre-commit.sample runs ok, so it appears that git can't find /usr/bin/env, or much else as I've tried shebanging it directly to ruby etc. Just /bin/sh is ok. So, where does Git get it's PATH? because it's not using mine or this wouldn't be happening. And more to the point, how do I get it to see /usr/bin/env ? I've tested the ruby script already, it works. Just to add: $ cat /etc/paths /usr/bin /bin /usr/sbin /sbin /usr/local/bin $ cat /etc/paths.d/git /Library/Frameworks/Git.framework/Programs The first few lines of the Ruby script (which runs via ./pre-commit or ruby pre-commit) #!/usr/bin/env ruby -wKU class String def expand_path File.expand_path self end def parent_dir File.dirname self.expand_path end end

Gigabyte H55N-USB3: No video on HDMI

- by newt

I built a new PC with a Gigabyte H55N-USB3 / Intel Core i5 650. With a monitor plugged in the DVI port, everything works fine. I installed Windows 7 32-bit and enabled remote desktop connection. After that, I unplugged the monitor, plugged it into network and installed everything else (drivers, programs, etc) via RDP. However, when I try to use the HDMI port on my TV nothing appears. Neither during the boot, neither after Windows starts. The TV says there's "no signal" (if I remove the cable the message changes to "check cable"). The cable is new, and it is working fine with my home theater on same TV (by the way, it is the cable which came bundled with the home theater). Video driver is the latest from Intel site. Anyway, this shouldn't be the problem since there is no image during the boot. Any ideas or tips would be welcome. I'm googling around but found nothing useful, yet.

Slow connection to Linux MySQL from Windows only (XAMPP)

- by Josh

I'm having a problem with a PHP project (using Kohana 3.2 framework) on my Windows 7 64-bit machine connecting to the database. The development database is stored on a Ubuntu Linux server on the local network. Other development machines running OSX and Linux are connecting fine. There are no other Windows development machines to test with. I can access MySQL fine using MySQL Workbench, and other projects (which I believe to be less database heavy) run mostly ok, only occasionally getting timeout messages. I'm constantly getting Maximum execution time of 30 seconds exceeded when functions such as mysql_query() are run in this particular project. Specifically, the Kohana file where the timeout occurs is MODPATH\database\classes\kohana\database\mysql.php [ 186 ]. My local set-up is: Windows 7 Professional 64bit XAMPP 1.7.7 (PHP 5.3.8) The output of uname -a of the Linux server is: Linux peach 2.6.38-11-server #50-Ubuntu SMP Mon Sep 12 21:34:27 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux I've tried the following, with no success: Disabling Windows firewall Switching between using a persistant and normal connection In my.cnf, adding skip-name-resolve Increasing wait_timeout Enabling bind-address I've run out of ideas now, and have no idea how to debug an odd issue like this. Has anyone come across this before, or have any idea how I could find the root of the issue, or what might be the problem?

Application Pool Identity corruption

- by Gavin Osborn

I have observed a few times while deploying software into IIS that every now and again the related Application Pools fail to restart and in the Event Log we see an error like the following: The identity of application pool, 'AppPoolName' is invalid. If it remains invalid when the first request for the application pool is processed, the application pool will be disabled. This does not happen frequently but when it does the only solution is to re-apply the Identity password in the IIS Manager Window. As soon as I re-apply and then restart the application pool the web sites come back up. Facts: The account is a service account whose password never expires. The account is local to the IIS host. The account password is never changed. This is IIS 6 running on Windows Server 2003 Deployment of the software is via MSI and involves several IIS Resets. The software is created in house and does not do anything fancy to IIS. Any ideas how the identity information might become corrupt? Edit: Clarification To be clear - this user account and password combination work absolutely fine and usually works fine as the Identity of the Application Pool. It is only when we deploy updates of our software into an existing IIS application that it stops working. Our password has not changed Our deployment does not change the password or reconfigure the application pools. This does not happen every time, 1/20 times perhaps. If we re-enter the password into IIS and restart the App Pools everything works.

Xen virtual host can reach some sites but not others

- by Tun H S Lee

Okay, this is killing me. Debian Squeeze, Xen 4.0, brand new install. No iptables rules whatsoever except for the ones added by the default xen bridge script. Dom0 can reach the entire world, no problems. DomU can receive packets from some hosts, but not from others. For instance, if I ping Host A, it works fine. If I ping Host B, the DomU reports 100% packet loss. The hosts are random, but consistent (even after reboots). I can see no pattern to why some work and others don't. In fact, in some cases, different virtual hosts on the same server (an other server at a different data center) are divided; some work and others do not. I can reboot (DomU or Dom0 too) and the same hosts will work or fail as before. If I tcpdump on the Host B while pinging from the DomU, everything looks fine. It sees the echo request coming in and says it's sending one back. However, if I tcpdump peth0 on the Dom0, it never sees the echo reply. Any ideas what could be happening? I'm tearing my hair out here.

How do I get a network printer installed in ubuntu 9.04?

- by SoaperGEM

My girlfriend's work computer now has Linux on one of the partitions, and for the most part it's running fine--except that I can't seem to get the network printers configured right. There are two of them: a Lanier MP 7500/LD275 and a Lanier MP C3000/LD430c, and Linux seems to have found them both automatically. I'll go through the steps of what I did, and what exactly went wrong. I went to Administration Printing, and clicked the new printer button. It searched for printers and found them both, listed under "Network Printers." I added them as new printers in succession. However, when I clicked "Print a Test Page," it failed saying there was a broken pipe. The device URIs were saved as socket://[ip address]:9100. I changed these to lpd://[ip address] per some online tutorial, which at first looked like it might have worked (but didn't). Then when I tried to print a test page, it first said Processing (and sometimes even Processing - printing test page, 4%, but always subsequently displays Idle - /usr/lib/cups/backend/lpd failed. Help! What do I do? It seems like Linux can find these printers just fine, and the drivers seem to be in place, so what's going wrong?

Can't access server sound card when vnc'd into ubuntu server

- by Corey Kennedy

I've set up my ubunutu 10 server with xfce, nxserver, and now tightvncserver so that I can control it remotely from my Windows 7 laptop. NX is working fine for remote access, but when I run (for example) exaile, no sound will be sent through the server's sound card. I installed tightvncserver and connected, but ran into the same problem. Exaile opens, sound isn't muted, I can see that sound cards are installed (via cat /proc/asound/cards), but I can't seem to get the remote sessions to access the server's sound card. Also, just to confirm that the sound card was working I hooked up a montior/keyboard to the server and opened a local xfce session. That worked fine. While I had the local session running, I was also able to open a remote session with NXClient and start exaile - which then successfully piped sound to the local card. After disconnecting the monitor/keyboard and moving the box back to its normal spot, though, I was not able to play sound via either an NX or VNC session. Does anyone have any suggestions? Surely it's possible to configure my remote sessions to pipe sound to the server's sound card, right? Or at least get xfce up and running without a monitor or keyboard but with access to the sound card so I can VNC into it? Thanks!

Nginx + Apache + Wordpress redirects to localhost/127.0.0.1

- by jcrcj

Anyone know how to fix an issue with Nginx + Apache + Wordpress redirecting to localhost/127.0.0.1? I've tried a lot of different fixes, but none have worked for me. I can go to http://domain.com/wp-admin just fine and use everything there normally. But if I try to go to http://domain.com it redirects to 127.0.0.1. Everything also works fine if I just run through Apache. Here are the relevant portions of my nginx.conf: server { listen 80; server_name domain.com; root /var/www/html/wordpress; location / { try_files $uri $uri/ /index.php; } location ~ \.php$ { proxy_pass http://127.0.0.1:8080; } } Here are the relevant portions of my httpd.conf: Listen *:8080 ServerName <ip> <VirtualHost *:8080> ServerAdmin test@test DocumentRoot /var/www/html/wordpress ServerName domain.com </VirtualHost> This is what my nginx log loks like: <ip> - - [19/Jun/2012:22:35:35 +0400] "GET / HTTP/1.1" 301 0 "-" "Mozilla/5.0 This is what my httpd log looks like: 127.0.0.1 - - [19/Jun/2012:22:24:46 +0400] "GET /index.php HTTP/1.0" 301 - "-" -- WordPress Address (URL) and Site Address (URL) both have same http://domain.com

Need help toubleshooting PC

- by brux

I have had problems since my dog pee'd on my computer. Problem: loads windows fine, at random intervals from 5 minutes to 30 minutes it restarts itself. There is nothing in the event log such as errors, no BSOD, just cold restart. after restarting - sometimes- it POST's and restarts itself at the end of POST. It will do this many times and then finally load windows. The cycle then begins again, it will restart eventually. What I have done: I thought it was HDD at first, since this is the only part of the computer which actually got wet with any fluid ( the case is off the PC and the dog pee'd down the front where the HDD is located). Seatool, the seagate HDD tool, found errors when I ran it inside windows, so I ran it in DOS mode from boo-table USB and ran it. It found the same number of errors and fixed them all. I ran the scan again and it says "Good". I loaded windows and ran the scan and it also said "Good there. So the HDD appears to be fine but the problem persists, random restarts. What else could this be? I have taken the computer apart and cleaned everything and also taken the PSU apart and cleaned it thoroughly. The problem still persists, what should my next steps be?

bind9 - forwarders are not working

- by Sarp Kaya

I am experiencing an issue with bind. If i want to resolve any domain name that is on the zone file. It works fine. However, when I try to resolve anything that does not belong to the zone file. I know that actual DNS servers that are being forwarded are working fine. But somehow bind9 fails to use them. The content of /etc/bind/named.conf.options is: options { directory "/var/cache/bind"; forwarders { 131.181.127.32; 131.181.59.48; }; dnssec-validation auto; auth-nxdomain no; # conform to RFC1035 listen-on-v6 { any; }; }; I have also tried to use only one ip address and it still did not work. also the content of /etc/bind/named.conf is: include "/etc/bind/named.conf.options"; include "/etc/bind/named.conf.local"; include "/etc/bind/named.conf.default-zones"; So there is no problem with including options file. Any recommendations for fixing this problem?

We have several "router" machines that gather a lot of external IP addresses on the same host and redirect, NAT or proxy the traffic to the internal network. They also act as routers for the machines on the internal network. This works fine, however I am unable to make the routing table, so I can change the source address, based on the destination a machine from the internal network want to access. Let's say I have a router, that has public addresses P1 (5.5.5.1/24) and P2 (5.5.5.2/24). All traffic goes through P1, but if necessary, the host is reachable on P2 too. This looks like this and works fine: > ip addr ... 1: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether aa:bb:cc:dd:ee:11 brd ff:ff:ff:ff:ff:ff inet 5.5.5.1/24 brd 5.5.5.255 scope global eth1 inet 5.5.5.2/24 brd 5.5.5.255 scope global secondary eth1:p2 ... Now I want to use P2 as the source address, if I want to access the Google DNS service for example (8.8.8.8). So I add a row in the routing table like: > ip route add 8.8.8.8 via 5.5.5.254 dev eth1 src 5.5.5.2 > ip route ... default via 5.5.5.254 dev eth1 5.5.5.0/24 dev eth1 proto kernel scope link src 5.5.5.1 8.8.8.8 via 5.5.5.254 dev eth1 src 5.5.5.2 ... But this does not work. If I ping 8.8.8.8, the host still uses P1 as the source address, and does not use P2 at all for outgoing connections. Am I doing it right? I guess not...

Unable to set initcwnd on a Hetzner server

- by Sergi

We just ordered a bunch of Hetzner EX40SSD servers with the minimal Debian install image that they provide and everything is just fine except that looking at tcpdumps for fine tuning the network from various locations the initcwnd param seems to be stuck at 6 no matter how we change it. By default Debian 3.2 kernels should have that setting to 10 so it's pretty strange. Is it possible that the NIC driver or a custom setting in the Hetzner Debian image is limiting this param? Even if we set it to 4, like the old kernel default, it doesn't work. Any ideas would be much appreciated! Does anyone know if the NIC drivers provided by default by Debian have some kind on limitation. In a long thread in http://www.webhostingtalk.com/showthread.php?t=1200617&highlight=hetzner they talk about a page http://wiki.hetzner.de/index.php/Installation_des_r8168-Treibers/en where Hetzner states that the included Realtek r8168 driver is not working properly, but nowhere do they say that the initcwnd could be affected. Tomorrow i will try to install a CentOs image and see if Debian is the problem...Last resort would be to install a custom debian image, but that is a pain in the ass! Thanks!
