• Windows 7 ssh file server.

  - by Siriss

  Hello all- I have looked at the other posts, but have not quite found an answer I have a question about windows file sharing over SSH. I have copssh installed and it is working for Remote desktop connections. I have port 22 forwarded on my router etc. I connect from a Mac or Putty with this address: ssh -l copsshusername 3391:localhost:3389 [external ip] That works fine. I would like to configure Windows 7 to allow my ssh account that I use to login, access to certain shared folders. I have documents and videos and things that I would like to be able to download externally. I have done this before on Linux and a long time ago on XP, but I cannot figure out what I am missing on Windows 7. There is a designated SSH user that copssh uses to run the service and that I use to to login as. I have googled and googled and have not found a solution that does everything I need that is why I am turning here for ideas. I hope I am explaining this correctly. Thank you very much for your help!

• Windows 7 Automatically Connecting To Unsecured Wireless Networks On Startup

  - by Xtend

  Most of the questions on this topic related to folks connecting to somebody else's wireless network when their own was available and could remedy the situation by going to their connections and unchecking the "connect automatically" box. See this: " Avoid automatically connecting to wireless network on windows 7 " as an example. In my situation, I've noticed that Win 7 will automatically connect to any unsecured wifi network - even if I have never connected to it in the past. If I am traveling and boot Win 7, it will start and connect to what appears to be the best signaled unsecured network without prompting me for confirmation (note: in the above link, "Naveen" seems to have same problem). Obviously, that is a security concern to me. Further, when I open "Network and Sharing" and "Manage wireless networks" the network is not displayed (probably because I labelled it a public network). Again, these are new, never connected with before, wireless networks. I always promptly disconnect from them but don't want to have to be on constant guard for an auto connection to a malicious network. This began about a month ago, as I recall, Win 7 did not behave like this in the past, I didn't monkey with wifi settings, and don't use a 3rd party connection manager. I did have to download some internet security certificates for army website access but I don't think that should mess with network settings. Any ideas how I can tell Win7 cease automatically connecting to networks or, at least, to prompt me for a confirmation before connecting?

• SSH Interactive mode not working

  - by Ekin Koc

  I have a Debian based linux server running for a year or so, without any problems. A couple of days ago, ssh interactive mode stopped working for no reason. I mean, I can open an ssh connection just fine, the server greets me with shell but I just can't type anything. However, if I send commands like this: ssh [email protected] cat /var/log/messages, I get the response. I dug through several logs and found one message, which feels remotely relevant to the problem; sh kernel: [10222733.062511] ------------[ cut here ]------------ sh kernel: [10222733.062522] WARNING: at /build/buildd-linux-2.6_2.6.32-39-amd64-7yVIH2/linux-2.6-2.6.32/debian/build/source_amd64_none/drivers/char/tty_ldisc.c:738 tty_ldisc_reinit+0x46/0x7b() sh kernel: [10222733.062526] Hardware name: PowerEdge R210 II sh kernel: [10222733.062528] Modules linked in: ipt_MASQUERADE iptable_nat nf_nat nf_conntrack_ipv4 nf_conntrack nf_defrag_ipv4 ip_tables x_tables sha1_generic arc4 ecb ppp_mppe ppp_async crc_ccitt ppp_generic slhc loop snd_pcm snd_timer snd soundcore snd_page_alloc i2c_i801 i2c_core pcspkr evdev joydev dcdbas container button processor ext3 jbd mbcache sg sd_mod sr_mod crc_t10dif cdrom usb_storage usbhid hid mpt2sas ahci ehci_hcd libata scsi_transport_sas usbcore bnx2 nls_base scsi_mod fan thermal thermal_sys [last unloaded: scsi_wait_scan] sh kernel: [10222733.062568] Pid: 8662, comm: sshd Not tainted 2.6.32-5-amd64 #1 sh kernel: [10222733.062569] Call Trace: sh kernel: [10222733.062572] [<ffffffff811ff056>] ? tty_ldisc_reinit+0x46/0x7b sh kernel: [10222733.062574] [<ffffffff811ff056>] ? tty_ldisc_reinit+0x46/0x7b Is there any way to get back the sshd working in interactive mode? I tried restarting sshd but that is no help. And somehow, I can not reboot the server. Tried sending shutdown -r now and reboot but it refuses to go down. Should I go ahead and request a physical reboot?

• checksecurity / setuid changes, is this a bug or did somebody break in?

• Metacity/Compiz not staring upon Login Ubuntu 10.10

  - by Ryan Lanciaux

  TLDR: As of this afternoon, I do not have a window manager when I login to Ubuntu 10.10. I would like to have window manager on login without needing to add to startup. Just started using linux again as my home OS. (Used it for a long time years ago but been on windows up until this past weekend) so this may be kind of n00b-ish :) Anyways, up until today, everything on my machine was running okay. I did not have compiz running as the default wm because I'm running NVidia Drivers and Xinerama (and as I understand Xinerama & Compiz don't work well together). I made no changes to my xorg / etc but today when I logged in, I had to manually start metacity from command line to get any window manager. Really not sure what would be causing this or what I can do to get it working again. My xorg.conf is available here: https://gist.github.com/845618. My default Window Manager is set to /usr/bin/metacity in Configuration Editor under /desktop/gnome/applications/window_manager. p.s. Any tips on how to run 3 monitors where I can move windows between screens without Xinerama would be appreciated but that's prolly for another thread :)

• IIS6 Sending a 404 for ".exe" files.

  - by Tracker1

  Recently a bunch of files I had setup for download via IIS6's web server stopped working. They are a number of setup files ending in ".exe" and were working prior to a few months ago. I have the file permissions set properly, and even enabled browsing in IIS to determine that the paths are indeed correct. I'm not sure if it is related, but the directories with a period stopped working as well. ex: "~/download/ApplicationName/0.9/AppName-setup-0.9.123b2.exe" When I rename the directory to say 0_9 the browsing works, but the file itself delivers a 404 message from IIS. For now, I've setup FileZilla FTP for anonymous access to these files, but would prefer to continue using IIS. I've considered creating an HTTP handler to serve the .exe files, but would really prefer a configuration solution. I just can't figure out why it isn't working, as all the settings are correct. Directory is setup for read access. "Everyone" has read permissions on the files themselves, and the directory browsing (aside from the folder "0.9" to "0_9" rename) shows the files.

• ESXi 5 VM Putty session hangs, vSphere client timing out

  - by user192702

  First of all I believe this is a ESXi issue but let me know if you have seen this. It started about a year ago when I noticed occasionally when I putty via SSH to my VM guests, if I do anything that makes it to display a lot of things at once, the session will hang and I have to start a new one quite often only to find the same behaviour. What I meant by display a lot of things can be any of the following: 1) tail -f filename 2) Paste a long command 3) less filename If I type in one character at a time this won't happen. I tried searching online and it always point me to flow control settings and the various suggestions I've tried have never been able to resolve the issue. Since last week, I've noticed I'm not able to connect to my POP3 server from Outlook (it's timing out from Outlook's perspective). Today I tried to connect to the ESXi via vSphere client and it gives me a time out also. Exact behavior and error I saw is similar to the one posted at the following URL but the suggested technique also failed to resolve the issue. http://davidcocke.blogspot.hk/2012/02/unable-to-login-with-vsphere-client.html Has anyone experienced this before? Any suggestions on how to troubleshoot this?

• Vista Screen resolution Changes when Switching Users

  - by Benjol

  I regularly have a problem when switching between users in Vista - the screen resolution drops down to 800x600. If I try to set the resolution back to the maximum, it says nothing, but just keeps it at 800x600. I can set it back to an intermediate value. Otherwise I have to either restart the PC, or sometimes if I log off one of the users, I can then set the resolution back to max. Might it also have something to do with using sleep mode instead of performing regular shutdowns? I thought it might be related to the desktop background image taking up too much space, but even with plain colours, the problem still occurs. There is an enormous thread on this here, but not really any answers. From what I can gather from that thread, it isn't related to any particular applications, nor limited to a particular make of graphics card or monitor, so I don't think that including hardware details is useful. This is a very annoying problem, as it screws up my desktop and screen layout every single time. Has anyone here experienced this problem or found a solution? I've noticed that Windows Update has tried to install nVidia updates and apparently they've failed on several occasions. Not sure if that is of any relevance or not. UPDATE The last post on the thread: FWIW - I had this problem for about 2 years and wrote a number of posts in this thread in the past. It survived OS reinstallation, change of practically all of my hardware piece by piece (mobo, cpu, monitor, graphics card, memory, power supply...) I used to be affected by this annoying problem at least once every 24-48 hours. About 1.5 months ago I wiped out my 32 bit vista ultimate installation and installed Windows7 ultimate 64 bit from scratch and never saw this problem again. GOOD RIDDANCE. Vista was a pathetic piece of __ that felt like a flashback to the old [horrible] NT4/Windows95 days. I was seriously considering switching over to Apple/Mac OSX if this problem persisted.

• Bad Intel DQ965GF motherboard? Fails memtest, but memory is good.

  - by Boden

  I've got a machine with a DQ965GF motherboard. Two days ago it started locking up hard. Ran memtest 3.3, 1.7, and TestMem 4. TestMem just freezes, memtest failed on moving 8 bit inversions. Letting memtest run eventually causes the system to restart. I pulled memory sticks one by one, and then replaced the memory with a couple of known good sticks. No luck. I switched power supplies, didn't help. Swapped video cards just to be safe. No help. When I start the machine I get a single beep before it POSTs. According to the manual, a single beep means: 1 beep - Refresh Error (with nothing on the screen and it is not a video problem) I'm assuming that the motherboard has failed since it's obviously not a RAM or power issue. Do you agree? NOTE: I also tried resetting BIOS defaults, and even flashed the BIOS to the latest version. I also ran the Mersenne Prime Test and the CPU seems to click along just fine. (Tried logging in to superuser with openid but it's not working for me today. Hope this gets through)

• KeePass lost password and/or corruption due to Dropbox/KeePassX

  - by GummiV

  I started using Keepass about a month ago to hold my passwords and online accounts info. Everything was stored in a single .kdb file, only protected with a password. I'm using Windows 7. Now Keepass can't open my .kdb file with the error "Invalid/wrong key". I'm fairly confident I have the right password. Altough I might have mixed up a few letters I've tried about two dozen different combinations to minimize that possibility - but can't rule it out though. My guess is however that the .kdb file got corrupted, either due to Dropbox syncing (only using it on one computer though) or because I edited the file using KeePassX on Ubuntu (dual boot on the same computer, accessing a mounted Win7 NTFS partition), or possibly a combination of both. I have tried restoring older versions(even the original one) from Dropbox and trying out all possible passwords without any luck. (which does seem to rule out KeePassX as the culprit, since oldest copies are before I edited the file from Ubuntu) I have tried opening the file with the "Repair KeePass Database file" which always gives the "0xA Invalid/corrupt file structure" (the same error for when a wrong password is typed). I was wondering if there was any way for me to salvage my hard-gathered data. I know generally that brute force cracking is not feasible, but since I can remember probably more than half of the usernames/passwords, any maybe the fact that one of them does come up fairly often (my go-to pass for trivial stuff), that might simplify the brute force process to a doable time frame. Maybe the brute-force thing might incorporate the fact that I know the password length and what characters it's made from. (If we assume corruption, not a password-blackout on my part) I could do some programming if there are any libraries or routines that I could use. Other people seem to have had a similar probem http://forums.dropbox.com/topic.php?id=6199 http://forums.dropbox.com/topic.php?id=9139 http://www.keepassx.org/forum/viewtopic.php?t=1967&f=1 So hopefully this question will become a suitible resource for people when searching the web. Feel free to tell me if you think this should rather be a community wiki.

• Identifying Service Error in Fedora 16

  - by Cerin

  How do you find the cause of a failed service start in Fedora 16? The new systemctl command in Fedora 16 seems to horribly obscure any useful logging info. [root@host ~]# systemctl start httpd.service Job failed. See system logs and 'systemctl status' for details. [root@host ~]# systemctl status httpd.service httpd.service - The Apache HTTP Server (prefork MPM) Loaded: loaded (/lib/systemd/system/httpd.service; enabled) Active: failed since Thu, 21 Jun 2012 16:26:56 -0400; 1min 23s ago Process: 2119 ExecStop=/usr/sbin/httpd $OPTIONS -k stop (code=exited, status=0/SUCCESS) Process: 2215 ExecStart=/usr/sbin/httpd $OPTIONS -k start (code=exited, status=1/FAILURE) Main PID: 1062 (code=exited, status=0/SUCCESS) CGroup: name=systemd:/system/httpd.service So the first command fails...and it tells me to run another command...which simply tells me that the command returned an error code. Where's the actual error? Even more frustrating is nothing seems to have been written to the logs: [root@host ~]# ls -lah /var/log/httpd/ total 8.0K drwx------. 2 root root 4.0K Jun 21 16:19 . drwxr-xr-x. 21 root root 4.0K Jun 20 16:33 .. -rw-r----- 1 root root 0 Jun 21 16:19 modsec_audit.log -rw-r----- 1 root root 0 Jun 21 16:19 modsec_debug.log

• Laptop Overheating with Windows 8

  - by Dany Khalife

  I recently installed Windows 8 on my HP G62 Laptop and i have been noticing a very strange problem with it. Let alone, for lets say 5 minutes, without even touching it, it starts to heat up and it reaches about 60 degrees (Celsius) with absolutely no applications open (not just on desktop but overall). I dug in a little deep and found out that Maintenance was running when the computer was Idle, so i turned that off From the System's Task Scheduler, and while there i also turned off other services i did not need hoping that would solve the problem. So after a few days, i noticed that the average temperature of my laptop dropped from 55 to 48 degrees while working on Visual Studio. And when i thought the problem had disappeared, it still did show up, only not after 5 minutes, but more like 10 minutes... Here is what i have done so far: Replacing the thermal paste on the CPU and the fan and cleaning the fan (this was like 6 months ago) Using a laptop cooler Running a virus scan (i just formatted my laptop so it would be really weird if i already caught something but who knows) Right now, i believe it has something to do with my gfx driver (Even though it IS up to date, looking closely at the screen, i can see the pixels slowly refresh (kinda like watching static on TV) which i wasn't able to do on Windows 7. If you have any ideas, let me know. Thanks

• Mouse clicks suddenly stopped working in Ubuntu

  - by DisgruntledGoat

  This is a weird one. For some reason, last night my mouse partially stopped working. Movement is fine, but the mouse buttons don't work. Mainly it's the left button, but occasionally the right click and scroll-wheel fail too. Initially I thought it could be the mouse itself (the left button seemed to get a bit "soft" recently), but I tried another mouse and had the same issue. Both are USB wireless optical mice. The keyboard is working okay 95%, only problem is Alt+Tab doesn't seem to work. Both keys work fine independently. At the time it happened I was using Chrome, I dragged to scrollbar to scroll and when I released the mouse it was still holding scrollbar. I'm using Ubuntu 9.10, I upgraded weeks ago and everything was working fine so I don't think it's related to that. I also hadn't run any updates (I have now just in case something fixed it). But no luck. Any ideas?

• Need help finding a program to split PDFs based on text in specific areas

  - by Sean

  I reeeeally need help with this. I work for a University in the admissions office and we get large PDFs of every document that an applicant uploads to us. What I need to do is split these PDFs into separate documents. Each of the separate documents has a head at the top of what type of document it is (Statement of Purpose, Transcript, etc). I found a program a few weeks ago that at first seemed to work great (A-PDF Splitter). It would look for every type of document in a combined PDF (eg. Statement of Purpose), and if it saw that heading it would create a new PDF named "ORIGINALFILENAME-Statement of Purpose". I soon discovered though that the program breaks for no reason on certain PDFs, and I have to take the time to take that PDF out of the queue and start the splitting over again (and we get 250 a day). I contacted their support and they basically told me I was SOL. So please, if you can find me a program to split PDFs into smaller PDFs based on if it finds particular text in a region, then I would be forever in dept to you. If I don't find one soon then I'm going to be spending the entire day splitting PDFs by hand and my boss isn't going to be happy.

• How can I restore my laptop from Windows 7 to its original Windows Vista recovery partition?

  - by Cam Jackson

  I bought my Acer laptop 4 years ago with Vista Home Premium x86. It has a recovery partition that I have used successfully in the past to format everything and reinstall Windows to factory settings. I have since upgraded to Windows 7, but I now need to get back to my original installation. Not sure what it's called, but I can successfully get into this recovery thingy: However, when I click the third option (for me I think it says 'Windows Image Recovery' or something like that) it tells me that it can't find any images to recover from :( I have checked and I don't have a windows.old that I can recover from either. One final note, if I launch diskmgmt.msc, these are the partitions: Why is the first partition shaded? Does that mean anything? Both of the 'unlettered' partitions are 100% empty. Did the Windows 7 upgrade process format my Vista system recovery partition?! And finally: How can I get back to my factory settings? EDIT: I did see this question, but neither of the answers apply to my situation. Edit to address jdh's answer: From what I can tell, I never get the option to boot the Vista recovery partition. After hitting F10, I get this screen, except it's partition 2, and I don't have the IN/MINT bit: I hit Escape, and then I get this screen, except without Ubuntu listed, and without the auto-countdown thing: I hit F8, and then I get this screen: I hit Enter on the first option, I end up at the screen in the first screen shot. As I said, from there I click the third option, and it fails to find the image, which I guess makes sense if it's only looking for a Windows 7 recovery. So I either need to make the Windows 7 tool see the Vista recovery partition, or I need the boot loader (?) to let me select Vista earlier in the process. Any ideas?

• Problem Uninstalling Microsoft Internet Explorer

  - by Roger F. Gay

  On Windows Vista Home Premium (x64) I am trying to uninstall Microsoft Internet Explorer. The procedures explained all over the web involve going through the control panel to Programs and Features. If MSIE is listed there, then uninstall in the usual way. If it is not listed there, click Turn Windows features on and off and deactivate it there. But Internet Explorer is not listed in either place. Background: I initiated some process in MSIE a couple of months ago that caused all web pages to no longer save login information or remain logged in when requested. As you can tell from the way I described that, I don't remember what it was and have no way to simply reverse it. I had a few problems with .NET Framework as well. So, I've uninstalled all browsers except MSIE and uninstalled .NET Framework. I've reinstalled .NET Framework and all other browsers. I have not been able to uninstall MSIE. Have Tried: I tried installing over the existing installation, but auto-update must be keeping it nicely up to date. The attempt simply produced an information window telling me that my current version is more up-to-date than the new version I tried to install.

• Xampp can't start apachem windows xp

  - by jribeiro

  I formatted my computer a week ago. Installed wampp on windows xp, git and everything I needed. When I run git for the first time it told me it had a problem with my user folder (because of the accents) so I created a new user and migrated everything to the new one. After this wampp wouldn't start anymore. I uninstalled it and installed xampp which is what I'm using now. My problem is that even though I requesed xampp to install Apache as a service it isn't installed. It doesn't show in windows services screen. Xampp control panel shows mysql service running ok. When I click to install apache as a service it returns no error. When I click start apache no error is outputed. No file and no errors under c:/xampp/apache/log/ If I restart computer it says that apache service is not installed. I tried to reinstall wampp and the same problem occurs. If I run netstat -a -no nothing is running on port 80! What can I do??

• MacBook Air Keeps dropping Wi-Fi

  - by Robert Patrick

  So my MacBook Air keeps dropping Wi-Fi for some reason. It happens ONLY on my home network, and ONLY to my computer. I'm using a Linksys WRT54G router. I'm the only Mac on the network. Every other Wi-Fi network is perfectly fine, and every other computer on this network is fine. Many things can happen. It could say it's connected, but not be able to access the internet (whether it tells me that there's no internet access or not). It may just drop Wi-Fi altogether, and refuse to connect. Generally, if I unplug the router and plug it back in, it's all good. It also works if I restart my computer. This happens multiple times a day. Yesterday I did everything I know to get it to connect (restart router many times, restart my MacBook), and nothing worked. Eventually it just magically worked. How can I stop this from happening? We got a notice from Comcast a while ago saying that a bot called DNS Changer was detected on one or more machines on the network. I'm assuming that this can't be me, right?

• Best Practice - SQL 2012 & IIS in VMWare

  - by Dan Ribar

  We are pretty new to VMWare and looking for some thoughts on our environment. We have a VMWare cluster that has on one host: VM#1: MS Windows 2008 R2 Enterprise & SQL Server 2012 VM#2: MS Windows 2008 R2 Standard & IIS The IIS asp.net app talks directly to the SQL Server. We had this similar environment on physical servers a few months ago and just recently moved to the virtualized environment. Regarding the setup, we have not tweaked any of the vm resource parameters -- all is set as standard and all is working. What is observed is that the VMs seem to spool down and we get lags in response. Of course this sin't as fast as the old physical environment, but I am wondering if: *is it a good idea to run the SQL server and the IIS server on the same host? They are the only two VMs on it. The host is a new Dell R620 with 192 gb mem. does it make sense to change any CPU or memory reservations when it doesn't seem like there is any contention is there a way to keep the VMs spooled up to eliminate delays? This is a brand new squeaky clean vanilla install. What are your thoughts?

• 500 Error when logining into subdomain using codeigniter

  - by itsdanprice

  I have a website that has been setup and working fine for ages. It's built using Code Igniter. It's run using .htaccess files to restrict access and hide urls. All fine. Until a couple of days ago when we try to access http://admin.dealersupport.co.uk we get a 500 error (this is the back end of the site, held in a seperate subdomain.) Nothing else has changed on the server. I have tried restoring from a back up from when I know it was working. The problem persists. The only thing I can think of is that we recently upgraded to Plesk 11.0.9 and since then we have been seeing some Apache instabilities. The only thing that is thrown up by the error logs is this: Wed Nov 21 08:40:17 2012] [error] [client 94.31.24.129] Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden: /var/www/vhosts /dealersupport.co.uk/admin/index.pl, referer: http://admin.dealersupport.co.uk/login I have now added this to my .htaccess files Options +FollowSymLinks +SymLinksIfOwnerMatch RewriteEngine On And that seems to have eliminated that error from the error logs, but we are still getting a 500 error when we have logged into the backend. Can anyone help?

• Graphics Artifacts/ Texture Flickering

  - by Cerin

  Hey I been having some problems with artifacts in games. Sometimes textures flicker. Artifacts of various shapes and sizes show up usually after a couple games of dota 2. I built my computer almost exactly one month ago and it has been doing this pretty much from the start except before the artifacts I believe just flashed on screen fast enough to where I couldn't tell what it was but I still noticed. In dota I've seen green triangular artifacts among other things. I've tried running Furmark for a while but even though it pushes the gpu much harder than dota 2, there are still no artifacts. It maxes in furmark at about 60C and running every game I've tried on it at 40C. CPU and system temp don't usually get higher than 40C either. These are my system specs: Gigabyte Z68 Intel Motherboard 16 GB Gskill Ripjaws SDRAM DDR3 Sapphire Radeon HD 7770 GHz edition Intel Core i5-2500k (with built in gpu) Corsair 750 Watt PSU windows 7-64 bit I have the latest drivers for everything. What should I do about this? Try to RMA my graphics card? Are there other things that could be causing this?

• Dell Latitude D510 Runs From Battery But Not AC Adapter

  - by Jason George

  I have a Dell Latitude D510 that went belly up around two years ago. It will run from the battery, however, the wall adapter will neither power the machine nor charge the battery. Once the battery is dead, the machine is dead. Since it died I've searched repeatedly for solutions. I've tried a new AC adapter and even removed and replaced the DC jack thinking one of the solder joints might be bad. Both to no avail. After two years of searching I finally found the answer today. Since it's such a simple fix and I had such a hard time finding it I wanted to post the info for others (as it is apparently a common issue with the D510). -----SOLUTION----- It seems this is commonly caused by a cracked solder joint at pin 1 on an inductor filter pair (FL2) near the power jack. Pins 1 and 4 are ground and pins 2 and 3 are power. There should be 20V from 1 to 2 and 3. Anything less indicates a cracked joint that is increasing resistance and dropping the supply voltage. Repair simply requires reflowing all four pins with a little added solder for security. Detailed instructions can be found here. Dell Latitude D510 solder problem

• Mailgun Is Not Detecting My New MX Records

  - by Tyler Crompton

  When I issue a DiG command to verify my MX records, I get the following output: $ dig example.com MX ; <<>> DiG 9.9.5-3-Ubuntu <<>> example.com MX ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 47700 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 5, ADDITIONAL: 5 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;example.com.

Type | Priority | Enter This Value | Current Value -----+----------+------------------+-------------------- MX | 10 | mxa.mailgun.org | 10 mail.example.com MX | 10 | mxb.mailgun.org | 10 mail.example.com I updated these records three to fours ago. I know it said to wait up to twenty-four to forty-eight hours. But I feel that if it detected the other DNS changes, then it should detect the MX record changes. Am I being impatient or is this a legitimate concern? What do you suggest I do? Note: I'd create a Mailgun tag for this; I feel that it'd be appropriate, but I don't have enough reputation to do so.

• Oracle: Getting ORA-01195 and ORA-01110 when attempting resetlogs

  - by MacAnthony

  I am trying to get our database to startup. When I login to sqlplus and do a startup, I get the message: Total System Global Area 534462464 bytes Fixed Size 2215064 bytes Variable Size 331350888 bytes Database Buffers 192937984 bytes Redo Buffers 7958528 bytes Database mounted. ORA-01589: must use RESETLOGS or NORESETLOGS option for database open So I do a shutdown, startup mount (which works fine) and then run: SQL> alter database recover using backup controlfile until cancel; alter database recover using backup controlfile until cancel * ERROR at line 1: ORA-00283: recovery session canceled due to errors ORA-19909: datafile 1 belongs to an orphan incarnation ORA-01110: data file 1: '/<path>/system01.dbf' SQL> alter database open resetlogs; alter database open resetlogs * ERROR at line 1: ORA-01195: online backup of file 1 needs more recovery to be consistent ORA-01110: data file 1: '/<path>/system01.dbf' I know I've used instructions to get me past this error before, but I seem to be having trouble tracking it down. A bit of history: We wanted to refresh the data in this from another db so we attempted to do a expdb/impdb into this instance. The impdb did not complete correctly and got an end of file error message in it and hung (I still have the message in a log if it's important). Since the instance would start at this point, we decided to use the hotbackup process we have to restore the db. The hotbackups are from another server/instance. We went through the same process 2 weeks ago. At the point of recreating the control file is where we got to the issue above.

• How can I implement ansible with per-host passwords, securely?

  - by supervacuo

  I would like to use ansible to manage a group of existing servers. I have created an ansible_hosts file, and tested successfully (with the -K option) with commands that only target a single host ansible -i ansible_hosts host1 --sudo -K # + commands ... My problem now is that the user passwords on each host are different, but I can't find a way of handling this in Ansible. Using -K, I am only prompted for a single sudo password up-front, which then seems to be tried for all subsequent hosts without prompting: host1 | ... host2 | FAILED => Incorrect sudo password host3 | FAILED => Incorrect sudo password host4 | FAILED => Incorrect sudo password host5 | FAILED => Incorrect sudo password Research so far: a StackOverflow question with one incorrect answer ("use -K") and one response by the author saying "Found out I needed passwordless sudo" the Ansible docs, which say "Use of passwordless sudo makes things easier to automate, but it’s not required." (emphasis mine) this security StackExchange question which takes it as read that NOPASSWD is required article "Scalable and Understandable Provisioning..." which says: "running sudo may require typing a password, which is a sure way of blocking Ansible forever. A simple fix is to run visudo on the target host, and make sure that the user Ansible will use to login does not have to type a password" article "Basic Ansible Playbooks", which says "Ansible could log into the target server as root and avoid the need for sudo, or let the ansible user have sudo without a password, but the thought of doing either makes my spleen threaten to leap up my gullet and block my windpipe, so I don’t" My thoughts exactly, but then how to extend beyond a single server? ansible issue #1227, "Ansible should ask for sudo password for all users in a playbook", which was closed a year ago by mpdehaan with the comment "Haven't seen much demand for this, I think most people are sudoing from only one user account or using keys most of the time." So... how are people using Ansible in situations like these? Setting NOPASSWD in /etc/sudoers, reusing password across hosts or enabling root SSH login all seem rather drastic reductions in security.
