• Apache Consuming Resources

  - by Chris Edwards

  Our web server suddenly has been giving us load issues. After I restart Apache the load stays low for a few hours up to a day or so then its back up to around 3.0 until I restart Apache again. Any suggestions on tracking down what is causing this? Thanks!

• Difference between accessing a website using Local host and IP address

  - by Cdeez

  I have developed an ASP.NET website and deployed into my IIS server. Now to see that my IIS is installed fine, I type local host in my address bar, and I get the welcome screen of IIS and its documentation in a separate window. Now I gave the url of my website http://localhost/mysites/site2/Default.aspx I access my site. Also giving my IP address instead of local host like: http://192.168.1.46/mysites/site2/Default.aspx also works. Just out of curiosity I wanted to see what happens when I give my IP address in addressbar. It asks me a user name and password saying:The server 192.168.1.46:80 requires a user name and password. I donot know what user name and password it is asking, and as of my knowledge I thought localhost points to my own IP address internally. But what is the difference and also what username and password do I need for it? Update: On chrome and IE just giving localhost displays the welcome screen, but on mozilla, localhost is also asking for a username and password.

• USB keyboard stopped working in Ubuntu with error -71

  - by tapan

  I have a usb keyboard which was working perfectly till now (about a year since i have been regularly using ubuntu). It suddenly stopped working. It stopped working when I connected a USB HDD. Now the keyboard works randomly .. working for a while and then stops working for a longer time. Here is the dmesg output : [ 705.817076] usb 5-1: device not accepting address 8, error -71 [ 705.928032] usb 5-1: new low speed USB device using uhci_hcd and address 9 [ 706.336060] usb 5-1: device not accepting address 9, error -71 [ 706.448055] usb 5-1: new low speed USB device using uhci_hcd and address 10 [ 706.568044] usb 5-1: device descriptor read/64, error -71 [ 706.792049] usb 5-1: device descriptor read/64, error -71 [ 707.008060] usb 5-1: new low speed USB device using uhci_hcd and address 11 [ 707.128041] usb 5-1: device descriptor read/64, error -71 [ 707.352052] usb 5-1: device descriptor read/64, error -71 [ 707.456068] hub 5-0:1.0: unable to enumerate USB device on port 1 Based on the suggestions here i tried the following two things: echo -1 > /sys/module/usbcore/parameters/autosuspend echo Y > /sys/module/usbcore/parameters/old_scheme_first However, i am still facing the same problem. Can anyone help me out with this ? I'm using Ubuntu 10.04 Lucid Lynx.

• Windows 7 Not Recognizing Camera Nor iPhone as Camera

  - by taudep

  I've been struggling with this one for a few days. I've recently upgraded an older computer to Windows 7 Home Premium. Neither my digital camera (A Canon SD1200IS) nor iPhone are ever detected as cameras, nor ever show up as accessable in Explorer. With the Canon camera, no driver is required. It's supposed to work with the default Windows 7 drivers. However, in the Control Panel's Device Manager, I'm always seeing a yellow icon next to the "Canon Digital Camera" device. I've uninstalled the device and let Windows attempt to reinstall, but it can never find a driver to install. With the iPhone, it's very similar. One big difference, though, is that iTunes can see the iPhone and back it up, etc. However, again when I go to the Device Manager, there's a yellow icon next to the iPhone. I've uninstalled iTunes, reinstalled, rebooted, deleted drivers, and let Window try to reinstall the driver, but it can never find the driver. So there seems to be some correlation that my machine can't detect cameras properly, and that it might be even a lower-level type of driver I'm struggling with. I know that USB however, does work, because I have have an external drive hooked into the machine. I've gone through the web and tried two hours worth of fixes, without success. I feel like if I can get the Canon camera detected, then the iPhone will be on it's way to being fixed too. BTW, I couldn't really find anything of use in the Event viewer. Any and all suggestions welcome.

• Acer Aspire One (mini) mfgd 9/03 locks up also when plugged in

  - by LAURIE ANN

  My problem is almost the same as the Toshiba user (Toshiba A205-5804 freezes when plugged in): Well I have a Toshiba A205-5804 and the problem is that the screen freezes anytime I plug the pc into the external power supply, not as most of the computers having the same issue, my computer DOES freeze in safe mode, and I really can't bear this problem for much longer... It's not an overheat problem, the computer is not getting hot or anything related, I've tried already to change the AC adapter, to boot only with AC and no battery, and also all of these suggestions: The only difference in my case is: I can be using the battery and when it runs down, I can just close the lid and the system goes into hibernation mode. I then plug it in and let it charge. When I think it's finally charged, I can UNPLUG it, open the lid and all is running fine on the battery again. Note: the system was NOT shut down and it still runs as long as I remove the power plug before opening the lid. I have ALL the same issues as the other Toshiba user, also. I was a tech for 9 yrs in my own business and this one has not only stumped me, but anyone I have asked has never heard of this problem. Every repair center wants to charge me for diagnosis, even is they cannot fix it. I would really like to run this system along side of my new Acer Aspire 17" laptop as I need it to finish my grad school work. Any ideas would be GREATLY appreciated. Thanx, Laurie Ann

• If I can take a screen capture of a graphical anomaly, can it still be a hardware issue?

  - by Jay Carr

  I have a strange graphical anomaly going on my iMac right now (green and magenta boxes are appearing sporadically), I'm slowly trying to work through different possibilities but I thought I'd start with the basics: Can a graphical anomaly that I can screen capture still be a hardware issue? I know, it seems really obvious. If it's hardware, it should show up well after the operating system has had it's say. And since the operating system is (I assume) doing the screen capture, it seems like it shouldn't see the anomaly unless the problem is software in nature. But, as I've researched this problem I see a lot of people taking their computers in to service people for hardware issues and Apple then resolving said issue. To further complicate things, I also have Windows 8 installed via bootcamp, and the issues seems to be showing up there as well. Anyway, it feels like it must be a driver issue, since I assume that's what the two OSes have in common, but...I thought I'd come here for some disambiguation. In my case, yes, I can screen capture the anomaly (at least in OSX I can), so I assume it's somehow a software (or driver) issue. But I wanted to double check because the internet is being ambiguous...

• Dual boot nt4 and windows 98

  - by ItFinallyWorks

  I am trying to dual boot nt4 and windows 98 se (don't laugh - old computer). I have seen Microsoft's instructions for doing this, but it limits windows 98 to have a Fat16 partition (NT4's NTLDR doesn't understand FAT32) and therefore only 2GB of disk space. I really need it to have more than that. I started with Win 98 (on the 1st partition), repartitioned the disk, then added NT4 on the 2nd partition. NT4 took over the bootloader (as expected), so NT4 boots, but Win 98 doesn't. Right now I am working in VMWare so I can use nonpersistent hard drives (IDE like the real computer) to recover from errors easily. I've tried using XPs NTLDR using the instructions here: http://www.nu2.nu/fixnt4/ , but I got weird errors from NT4 and it never really worked. If XP's NTLDR would work, that should be able to boot both OSes. I've also tried using GRUB. In theory that should work. In fact when booting from super grub disk, it does. But as soon as I install grub to disk, Win 98 boots, but NT 4 blue screens at boot with a 0x0000007b inaccessible_boot_device error (that can be alot of things see MS kb 822051). The incantation I'm using for GRUB 1 is rootnoverify (hd0,1) makeactive chainloader +1 boot So, anybody have some suggestions?

• How to eliminate overscan on Ubuntu HTPC

  - by Norman Ramsey

  I'm using an Ubuntu box with Nvidia graphics card as an HTPC. My HDTV is a Sony Bravia KDS-R50XBR1; this is a rear-projection unit with many inputs. I am using the HDMI input. I'm using the proprietary Nvidia drivers and they recognize the 1080x1920 resolution just fine. The display is a little fuzzy but at 50 inches it's perfect for movies. My problem is that the TV has three overscan settings, and none of them reduces overscan to zero. When I was using dual-screen this was fine, but I'm moving to where the TV is my only screen, and the Gnome panels are not visible because of the overscan. I'd like to figure out how to eliminate the overscan, without trying to scale my 1080p content down to 920p or something ridiculous like that. Ideally there would be some scurvy trick, perhaps involving the TV service menu, to get rid of the overscan on the TV side. Or I could move the Gnome panels, but I still would be missing the edges of my movies. Suggestions most welcome.

• Scheduled task does not run on WIndows 2003 server on VMWare unattened, runs fine otherwise

  - by lnm

  Scheduled task does not run on Windows 2003 server on VMWare. The same setup runs fine on standalone server. Test below explains the problem. We really need to run a more complex bat file, but this shows the issue. I have a bat file that copies a file from server A to server B. I use full path name, no drive mapping. Runs fine on server B from command prompt. I created a task that runs this bat file under a domain id with password that is part of administrator group on both servers. Task runs fine from Scheduled task screen, and as a scheduled task as long as somebody is logged into the server. If nobody is logged in, the task does not run. There is no error message in Task Scheduler log, just an entry that the task started, bit no entry for finish or an error code. To add insult to injury, if the task copies a file in the opposite direction, from server B to server A, it runs fine as a scheduled unattended task. If I copy a file from server B to server B, the task also runs fine unattended, I recreated exactly the same setup on a standalone server. No issues at all. I checked obvious things like the task has "run only as logged in" unchecked, domain id has run as a batch job privilege and logon rights, Task Scheduler service runs as a local system, automatic start. Any suggestions?

• How can I restore my original IME Romaji input settings?

  - by JOhn K

  the this one, Japanese IME on Windows: switch back to romaji input method (3) did not help. The problem seems the same. My Vista home premium version PC, I had been using Microsoft IME to use English and Japanese input using romaji henkan for a long time. One day, all of a sudden, first when I started up the PC, it has cap lock indicator ON. So, I press SHIFT key, CAP lock indicator is off!(This I have to do every morning.) Now when I want to type romaji input to change to Japanese, I switch EN English (United States) to "JP Japanese (Japan) and select input to hiragana input. It worked until that day. But now when I set to input romaji for hiragana as I used to do and start typing, then it shows Japanese hiragana directly on the display just as keyboard setting as Japanese ???109???????? as shown in Wikipedia JIS keyboard. And I cannot show hiragana as I wanted ( I can convert to Kanji OK) etc. by hitting space key. But its key board arrangement is what I never learned. Other thing I found is when I hit "`" key, it switches between hiragana and alphabet. When I see Control panel setting it is the same setting as I have seen. Please suggest me a solution to get the original setting for IME input mode as I used to do. John K.

• Remote server security: handling compiler tools

  - by Gonzolas

  Hello! I was wondering wether to remove compiler tools (gcc, make, ...) from a remote production server, mainly for security purposes. Background: The server runs a web application on Linux. Consider Apache jailed. Otherwise, only OpenSSHd faces the public network. Of course there is no compiler stuff within the jail, so this is about the actual OS outside of any jails. Here's my personal PRO/CON list (regarding removal) so far: PRO: I had been reading some suggestions to remove compiler tools in order inhibit custom building of trojans etc. from within the host if an attacker attains unpriviliged user permissions. CON: I can't live without Perl/Python and a trojan/whatever could be written in a scripting language like that, anyway, so why bother about removing gcc et al. at all. There is a need to build new Linux kernels as well as some security tools from source directly on the server, because the server runs in 64-bits mode and (to my understanding) I can't (cross-)compile locally/elsewhere due to lack of another 64-bits hardware system. OK, so here are my questions for you: (a) Is my PRO/CON assessment correct? (b) Do you know of other PROs / CONs to removing all compiler tools? Do they weigh in more? (c) Which binaries should I consider dangerous if the given PRO statement holds? Only gcc, or also make, or what else? Should I remove the enitre software packages them come with? (d) Is it OK to just move those binaries to a root-only accessible directory when they are not needed? Or is there a gain in security if I "scp them in" every time? Thank you!

• How to install QEMU on Damn Small Linux?

  - by user2934303

  i'm trying to install QEMU on a Damn Small Linux installation in order to emulate pentium features in a 486 computer. Though DSL was descontinued, it's the only linux that runs reasonably on the 486 processor, most recent kernels doesn't even boot on 486 architecture. I tried Tiny Core Linux, but it doesn't work in 486, so i seem to have no escape here. The most recent image of DSL is from 2008, it uses kernel 2.4.x, and i couldn't find a way to compile QEMU on it. Firstly, it lacks several compile tools needed for compiling it, and, it have several dependency problems. I tried some pre-compiled packages, but the only one that worked was a QEMU 5.2 RPM package (it didn't had dependency problems), and it was way too old, it wasn't capable of running windows yet, it just gave me the option of emulating a code, not a full OS as windows, and it also didn't give me the option to choose which architecture i wanted it to emulate (-cpu option). Can anyone help me with this? Also, if someone can think of some alternative to it, i'd be grateful. Thanks.

• Package upgrade on Ubuntu raid server and grub setup issue

  - by RecNes

  I have remote Ubuntu 10.10 server running on raid system. I did package upgrade yesterday night for security reasons. During the upgrade, grub installation screen appeared and asked me which partition I wanted to install grub. Options are sda,sdb,md1 and md2. I decide to install them on both sda and sdb partitions. I wondering, was I make true decision? If machine get reboot is it can be boot up safely?

• PORT FORWARDING TO PUT MY WEB SERVER ON THE INTERNET

  - by Chadworthington

  I went to http://canyouseeme.org/ to check to see what my external IP address. Regardless of what port I enter, it tells me that the port is blocked. I have a LinkSys router that basically has the default settings with the exception that I have WEP encrptin setup and I have forwarded a few ports, including 80 and 69. I forwarded them to the 192.x.x.103 IP address of the PC which is running IIS. That PC runs Symantec Endpoint Protection, which I right mouse clicked in the tray to Disable. These steps used to make my PC visible so I could host my own web site in IIS on port 80, or some other port, like 69. Yet, the Open Port tool cannot see my IP when it checks eiether port and when I navigate to http://my external ip/ I get "page cant be displayed" At first I was thinking that maybe Comcast is blocking port 80, but 69 doesnt work eiether. I do not see any other blockking set up in my router and, as I mentioned, I went with teh defaults except where discussed. This is a corporate PC and Symantec End Point Protecion is new to it (this previously worked on teh same PC with Symantec Protection Agent), but I thought that disabling Sym End Pt from the tray, that that would effectively neutralize it. I do not have the rights to kill the program itself. Any suggestions on what else to try to make my PC externally visible?

• supervisord launches with wrong setuid

  - by friendzis

  I am trying to test a pilot system with nginx connecting to uwsgi served application controlled by supervisord running on ubuntu-server. Application is written in python with Flask in virtualenv, although I'm not sure if that is relevant. To test the system I have created a simple hello world with flask. I want nginx and uwsgi both to run as www-data user. If I launch uwsgi "manually" from root shell I can see uwsgi processes runing as appropriate user (www-data). Although, if I let supervisor launch the application something strange happens - uwsgi processes are runing under my user (friendzis). Consequently, socket file gets created under wrong user and nginx cannot communicate with my applicaion. note: the linux server runs as Hyper-V VM, under Windows Server 2008. Relevant configuration: [uwsgi] socket = /var/www/sockets/cowsay.sock chmod-socket = 666 abstract-socket = false master = true workers = 2 uid = www-data gid = www-data chdir = /var/www/cowsay/cowsay pp = /var/www/cowsay/cowsay pyhome = /var/www/cowsay module = cowsay callable = app supervisor [program:cowsay] command = /var/www/cowsay/bin/uwsgi -s /var/www/sockets/cowsay.sock -w cowsay:app directory = /var/www/cowsay/cowsay user = www-data autostart = true autorestart = true stdout_logfile = /var/www/cowsay/log/supervisor.log redirect_stderr = true stopsignal = QUIT I'm sure I'm missing some minor detail, but I'm unable to notice it. Would appreciate any suggestions.

• On Windows XP, Start > Run "My Documents" sometimes doesn't work

  - by Clayton Hughes

  On all of my home computers, I can enter "my documents" into the Start Run prompt and the My Documents folder of the current profile will open up. What's more, I can continue typing subfolders, files, etc. and auto-complete works and it's smart and enjoyable. I can't check at the moment, but I'm almost positive entries like "My Pictures" and "My Music" also go to their correct folders. On my work computers, if I enter "my documents" into the Start Run prompt, I get the following error: "Windows cannot find 'my'. Make sure you typed the name correctly, and then try again. To search for a file, click the Start Button, and then click Search." I can sort of circumvent this by creating a shortcut in my PATH named 'my' that points to My Documents folder, but this doesn't solve the auto-complete option (and it's otherwise imperfect, of course, because "my pictures" or "my music" all direct to the same place. A google search doesn't provide much help on this, although it does identify a poster in 2007 with this same question at another board: http://www.msfn.org/board/lofiversion/index.php/t124813.html (Login required, but Google cache available here: http://preview.tinyurl.com/ygxhwwl) Is this just a limitation of the networks belonging to a domain, or is there some way I can get this functionality back? My documents folder does live in the standard place (C:\Documents and Settings{username}\My Documents), and not on a network drive or anything. It's probably worth adding that the computers are part of some freakish Novell domain thing, too. I'm not in IT here so I'm not too up on the details. Thanks for any help/suggestions!

• Dynamically updating DNS records with NSUPDATE fails

  - by Thuy

  I've got my own nameserver ns3.epnddns.com and domain epnddns.com I wanted to try and update the records dynamiclly from home using nsupdate but when I run nsupdate -k Kwww.epnddns.com.+157+17183.key i get the following errors Kwww.epnddns.com.+157+17183.key:1: unknown option 'www.epnddns.com.'

Generated keys on my home pc, using dnssec-keygen -a HMAC-MD5 -b 128 -n HOST www.epnddns.com. created /var/named/ and put the keys there and chmod them to 600. transfered the keys to my nameserver ns3.epnddns.com, created /var/named/ ,put the keys there and chmod them to 600 made dnskey.conf in /var/named and added key www.epnddns.com. { algorithm hmac-md5; secret "my secret from they keys=="; }; chmod to 600 then in /etc/bind/named.conf.local include "/var/named/dnskeys.conf"; zone "epnddns.com" { type master; file "/etc/bind/zones/epnddns.com.zone"; allow-transfer { myhomeip; }; //its my home ip so not in the same network allow-update { key www.epnddns.com.; }; }; I restarted bind without any error messages so it seems to be working on the nameserver at least. But on my homepc when i try and run the nsupdate i get those error messages. Thanks in advance for any help or insightful advice.

• Flash alternative for iBook Mac?

  - by Hunter Dolan

  I have a old Apple iBook G4 that I decided to hook up to my main TV. I like the setup because I can surf the internet on my TV now. The only thing that I can't seem to do is watch Flash videos. Apparently Flash Player 10 doesn't play nice with the iBook's graphics card's GPU, leaving all the graphics processing to the CPU which is a disaster. Others suggested downgrading to Flash Player 9, I did that, and youtube worked fine, but Hulu (The main reason I wanted to hook it up to the TV in the first place) did not. Anyone know of a Flash alternative or a Flash 10 fix for the iBook? Or even a Hulu client that doesn't require Flash. Here are my iBook's Specs Model Name: iBook G4 <br> Model Identifier: PowerBook6,5 <br> Processor Name: PowerPC G4 (1.2) <br> Processor Speed: 1.2 GHz <br> Number Of CPUs: 1 <br> L2 Cache (per CPU): 512 KB <br> Memory: 512 MB <br> Bus Speed: 133 MHz <br> Boot ROM Version: 4.8.7f1 <br> Mac OS X Version: 10.5.8 <br> PS: Don't tell me that I need to buy a new computer. I know that I would have better results with a new computer but I don't want to buy a new computer just for Hulu.

• Acer Aspire one is falling apart on Ubuntu

  Question: How do I have my netbook detect and install hardware? Info: I have an Acer Aspire One, it came with windows XP and I loaded it with Win7. I decided I wanted to change to Ubuntu so I tried Ubuntu netbook remix, which failed horribly, and so after attempting 3 or so other OS's I ended with Ubuntu Desktop 9.10. Which worked fine for a while, but there were some minor issues so I asked a question about it here and decided to change my OS again. This last weekend I tried mandriva like that guy in my other question suggested, no success. when I had though my netbook lost the ability to use it's touch pad, I didn't think much of it, just thought it must be a driver or something. But When Mandriva failed, and I also while I was at it tried Damn small linux and Debian, which both failed to, I decided to switch back to Ubuntu Desktop(some where in here my keyboard stopped working for one attempt to). But first I gave the netbook remix one more try. it worked this time, with the exception of it didn't have any networking. I thought it was a driver issue again and finished the weekend with ubuntu desktop 9.10 again. But now things get really crazy. it doesn't know it has a wireless card or an ethernet card. It doesn't know my phone is connected trying to provide wireless broadband either. I'm clueless on what could be the problem. And with only a minimal amount of experience with Ubuntu can't navigate the entire interface with only my keyboard(it doesn't detect a USB mouse when I plug it in, it had when I installed it. in fact the network interfaces were working just fine when I live boot ubuntu to installed it). Even so, I don't know where to go or what to do to make it recognize it's hardware. I'm in a dire situation, any help is welcome.

• OSX: Mimic Ubuntu IP Masquerading via iptables with ipfw

  - by Dogbert

  Good day, I am attempting to replicate a setup I have between a router and an Ubuntu PC, and have the same setup working on my MacBook (10.6, Snow Leopard). First, I have a router that has a USB port. When I plug it into my Ubuntu PC, it creates an RNDIS connection, allowing me to connect to the router over the USB cable via an IP connection. When I plug it into my computer via USB, it gets assigned an IP address of 172.16.84.1, and a new adapter appears when I type ifconfig. I can then SSH into the device via ssh [email protected]. When I log in to the device, I flush the routes, then create the default route: admin@localhost> route -f admin@localhost> route add default 172.16.84.2 Now, in my Ubuntu machine, I use iptables to enable IP masquerading: root@Valhalla> sudo iptables -t nat -A POSTROUTING -s 172.16.84.2 -j MASQUERADE Once this is all done, the router has internet access over the USB connection to my PC. I am trying to replicate this exact setup on my MacBook now (Snow Leopard), but iptables does not exist for OSX, not even a Macports version exists. I have scoured through other questions on StackOverflow that cover the usage of the ipfw command, which apparently works as a drop-in replacement for iptables. However, the syntax is significantly different, and I'm pretty much lost. Does anyone with some experience with ipfw have some suggestions on how I could accomplish this and create a NAT connection via IP masquerading like I could with my Ubuntu PC? Thank you for your assistance.

• cannot send emails to other Web servers

  - by developer

  I'm trying to limit my server's open ports in CSF. The IPv4 port settings include: # Allow incoming TCP ports TCP_IN = "22,25,53,80,110,143,443,587,3654,53343” # Allow outgoing TCP ports TCP_OUT = "22,53,80,113,443,465,995,3654" # Allow incoming UDP ports UDP_IN = "53" # Allow outgoing UDP ports # To allow outgoing traceroute add 33434:33523 to this list UDP_OUT = "53,113,123" As you see, I have port 25 open in TCP_IN but have removed it from TCP_OUT. The reason is I wanted to have my mails transmitted over smtps, so I have port 465 opened instead in TCP_OUT. Since I am using Rouncube in Directpanel, I have also set the following in Rouncube's config.inc.php: $config['default_host'] = 'ssl://mail.mydomain.com'; $config['smtp_server'] = 'ssl://mail.mydomain.com'; $config['smtp_port'] = 465; However, when I remove port 25 from TCP_OUT, I no longer can send mails, say, to gmail, though I can send mails to own. But I can receive all mails. Please let me know if I need to make any further changes. Do I need to disable port 25 at all, to have my mails sent via ssl. Thanks

• Apache Alias Isn't In Directory Listing

  - by Phunt

  I've got a site running on my home server that's just a front end for me to grab files remotely. There's no pages, just a directory listing (Options Indexes...). I wanted to add a link to a directory outside of the webroot so I made an alias. After a minute of dealing with permissions, I can now navigate to the directory by typing the URL into the browser, but the directory isn't listed in the root index. Is there a way to do this without creating a symlink in the root? Server: Ubuntu 11.04, Apache 2.2.19 Relevant vhost: <VirtualHost *:80> ServerName some.url.net DocumentRoot "/var/www/some.url.net" <Directory /var/www/some.url.net> Options Indexes FollowSymLinks AllowOverride None Order Allow,Deny Allow From All AuthType Basic AuthName "TPS Reports" AuthUserFile /usr/local/apache2/passwd/some.url.net Require user user1 user2 </Directory> Alias /some_alias "/media/usb_drive/extra files" <Directory "/media/usb_drive/extra files"> Options Indexes FollowSymLinks Order Allow,Deny Allow From All </Directory> </VirtualHost>

• SeLinux blocking connection to sshd on Ubuntu 9.10

  - by Barton Chittenden

  When I try to log on to my laptop, which runs Ubuntu 9.10, the server rejects my login attempts. Checking /var/log/auth.log, I see the following: Feb 14 12:41:16 tiger-laptop sshd[6798]: error: ssh_selinux_getctxbyname: Failed to get default SELinux security context for tiger I googled for this, and ran across the following: http://www.spinics.net/lists/fedora-.../msg13049.html Here's the part that I think relates to the problem that I'm having: Quote: What's wrong on my system? Why it's not possible to login even if selinux is in permissive mode? Any suggestions? I'd start by trying to figure out why sshd isn't running in sshd_t (it seems to be running in sysadm_t). Paul. selinux mailing list selinux@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mail...stinfo/selinux Yes, sshd is running in sysadm_t: ps axZ | grep sshd system_u:system_r:sysadm_t 3632 ? Ss 0:00 /usr/sbin/sshd -o PidFile=/var/run/sshd.init.pi ls -Z /usr/sbin/sshd system_ubject_r:sshd_exec_t /usr/sbin/sshd Don't know why it's not sshd_t. I didn't modified something. It's a standard installation of sles11 with the default reference policy from tresys. Maybe this code snippet from policy/modules/services/ssh.te is responsible for that: Allow ssh logins as sysadm_r:sysadm_t gen_tunable(ssh_sysadm_login, true) Any ideas? Do you have boolean init_upstart set to on? if not try setting it to on. I do not believe ssh_sysadm_login boolean works currently but i may be mistaken. -- Yeah, setting init_upstart to on did the trick! THANK A LOT! Do you know why this prevents the user from logging in through ssh even if selinux is set to permissive?? Ok, so the million dollar question is "where do I set 'init_upstart=1'"? It's not clear from context which configuration file needs to be edited, and I'm not at all familiar with SELinux configuration.

• Wireless router blocking some sites while using ethernet is fine

  - by Micke

  I'm using Windows 7 and my router is a wireless Apple Airport Express that is approximately two years old. Suddenly I can't access some sites (for example www.sthlm.friskissvettis.se, or www.vegetarian-shoes.co.uk, some streamed tv-shows on svtplay.se, and a number of other random sites) when connecting to internet with my router. It worked good until recently and I'm fairly sure this problem emerged when my ISP upgraded from 10/10mbit to 100/10mbit speed. Most other sites like facebook and google works fine. When using my network cable to connect to internet everything works fine and I can access these sites. Firmware is current and I've tried reseting the router to factory defaults. Tried different browsers, and I can't ping the "blocked" sites either. Tracert www.sthlm.friskissvettis.se starts with 10.0.0.1 and continues through a number of long addresses until it says timeout. The last working address before timeout was sth-tcy-ipcore01-ge-0-2-0.neq.dgcsystems.net [83.241.252.13], if it matters. Tracert www.vegetarian-shoes.co.uk also eventually gives me a timeout. When the network cable is plugged in, I still get timeout on tracert www.sthlm.friskissvettis.se even though I can access the site in Chrome. Weird. www.vegetarian-shoes.co.uk doesn't give me a tracert timeout when the cable is plugged in, and I can access the site as usual. I've tried changing DNS servers to use opendns servers instead, but to no use. I've tried pinging these two sites with a lower MTU packet size (with this method: http://www.richard-slater.co.uk/archives/2009/10/23/change-your-mtu-under-vista-or-windows-7/), but still can't access them through ping... I don't know what to do anymore.... any suggestions???
