  • Cyrus IMAP: Unable to connect to remote host: Connection refused

    - by Nick
    I'm working on setting up a Cyrus 2.2 IMAP server on Ubuntu Server 9.04. If I telnet from the server itself: # telnet localhost imap I get: * OK IMAP Cyrus IMAP4 v2.2.13-Debian-2.2.13-14ubuntu3 server ready Which is what I should be seeing. If I try from another machine on the network: telnet 192.168.5.122 imap I get: telnet: Unable to connect to remote host: Connection refused UPDATE: From /etc/cyrus.conf # add or remove based on preferences imap cmd="imapd -U 30" listen="imap" prefork=0 maxchild=100 imaps cmd="imapd -s -U 30" listen="imaps" prefork=0 maxchild=100 #pop3 cmd="pop3d -U 30" listen="pop3" prefork=0 maxchild=50 #pop3s cmd="pop3d -s -U 30" listen="pop3s" prefork=0 maxchild=50 #nntp cmd="nntpd -U 30" listen="nntp" prefork=0 maxchild=100 #nntps cmd="nntpd -s -U 30" listen="nntps" prefork=0 maxchild=100 To the best of my knowledge, there is no firewall running on the box. I've tried restarting the saslauthd and cyrus2.2 daemons, with no effect. What else can I try?

  • Permanently change IP address on SuSE 10

    - by Long Ngo
    I am trying to change IP address of a SuSE 10 machine that is running Tomcat. I need to create a shell script to do this so could not use YaST. As some sites suggested on my Google search, I edited the files in /etc/sysconfig/network/ifcfg-eth-* to change the IP address. After that, I restarted the network service by calling /etc/init.d/network restart. The network card restarting just fine. I, then, restarted tomcat web service. However, when I browsed the new IP address using browser, I got an "Request denied" message. Can anyone please tell me how I could do this? Thanks

  • Server can't set IP after power outage

    - by Ali
    The power went out all of a sudden and when we tried to restart everything when it came back on - our server can't be assigned an IP? We got an error stating that the IP for the server was already in use by another system. We then shut down all systems and restarted the server but then for some reason the server was assigned an IP but no one could connect to it - after restarting the server after setting it to have a dynamically assigned ip - the server now has no ip - just 0.0.0.0 - running an ipconfig/renew or ipconfig /release has no effect.. what should we do!!

  • HAProxy -- pause/queue all traffic without losing requests

    - by Marc
    I basically have the same problem as mentioned in this thread -- I would like to temporarily suspend all requests to all servers of a certain backend, so that I can upgrade the backend and the database it uses. Since this is a live system, I would like to queue up requests, and send them to the backend servers once they've been upgraded. Since I'm doing a database upgrade with the code change, I have to upgrade all backend servers simultaneously, so I can't just bring one down at a time. I tried using the tcp-request options combined with removing the static healthcheck file as mentioned in that thread, but had no luck. Setting the default "maxconn" value to 0 seems to pause and queue connections as desired, but then there seems to be no way to increase the value back to a positive number without restarting HAProxy, which kills all requests that had been queued up until that point. (The "hot-reconfiguration" options using -sf and -st start a new process, which doesn't seem to do what I want). Is what I'm trying to do possible?

  • Sendmail background process sometimes processes queue, but sendmail -q always works

    - by markmcb
    I'm using sendmail version 8.14.4 on Fedora 15 to send email. My Rails app uses delayed_job to queue up emails. Messages will queue up in /var/spool/mqueue as expected, but don't always get processed. I can see the messages and sendmail is definitely running in the background. Restarting the process does nothing. However, when I issue the sendmail -q command, sendmail gets to work and starts sending. The really odd thing is that this behavior only occurs sometimes. Other times message queue up and are delivered as expected. I've tried tweaking various sendmail configs to reduce the time between queue processing (for example, adding define('confMIN_QUEUE_AGE', '0')dnl to /etc/mail/sendmail.mc), but nothing seems to do the trick. Any ideas what might be the root cause?

  • Checkpoint FW-1disk full

    - by krugger
    Hi, The logging filled the disk of the managment node. This cause the firewall nodes to start logging locally. After deleting some old logs, restarting the managment node logging is still being done locally at the firewall nodes. I have already done a fw fetchlogs on all firewall nodes to get the local log entries. How can I tell the firewall nodes that they should once again connect to the managment node? My syslog_servers show doesn't show any syslog servers. But the documentation mentions that this is for additional logging and not for logging between firewall nodes and the managment node.

  • PPTP VPN on OS X and iOS failed to connect Facebook and Youtube

    - by bGiraffe
    Thnaks for reading. I setup a VPN server on my Buffalo WHR-HP-G300N router at Macau, and use it for access website over China Firewall when i travel in China. On Android and Windows, everything work fine, however on my Macbook Air and iPad, it is not working. I can access blocked site like badoo.com but not facebook and youtube. If i ping it at terminal, it said "ping: cannot resolve facebook.com: Unknown host". After i read this http://cp.hidemynet.com/knowledgebase.php?action=displayarticle&id=26, i find i can restart my router and reboot my Macbook, and connect to VPN before any request to any blocked site so that i can successfully connect to facebook and youtube. However it works sometime but not always. It is really annoying because i need to work on VPN and my Mac, would anyone can help me to solve it? Rather than restarting my router and my Mac every time. Please HELP!!! regards

  • mac osx cannot connect to windows 7 machine

    - by Binary X
    I have a Mac OSX (Snow Leopard 10.6.6) setup on a network with several Windows 7 machines. When trying to place a large file on a Windows share the connection to the Windows share gets lost and I am unable to reconnect until I reboot the Mac. I know this is on the Windows side because the Mac can connect and transfer files to Server 2008 and XP without issue. Looking in the log file I see this message SharePointBrowser::handleOpenCallBack returned 12 I have tried restarting the com.apple.netauth.sysagent service but that did not resolve the situation. I can do an nslookup to the Windows 7 machine, but trying to ping the machine by hostname always gives a hostname lookup failure (I can ping via IP address). I cannot connect to the machine via IP adress either. Any help would be appreciated.

  • Amavis-new whitelist

    - by pigeon
    Hi to the Linux community. I'm coming from a Windows Server background so have mercy. I'm attempting to whitelist some domains and although I know this isn't the best way of doing so its just a one off for a couple of domains so I thought it would be the quickest way of doing so. Current setup: Amavis is used to pass emails off the ClamAV and SpamAssasin, currently I make changes in /etc/amavis/conf.d/50-user, as this will overide other settings. Have created a whitelist file that looks like this: .domaintowhitelist.com .domain2towhitelist.com In the 50-user config file: Have tried variants like this: read_hash(\%whitelist_sender, '/etc/amavis/whitelist'); read_hash(\%virus_lovers, '/etc/amavis/whitelist'); And restarting amavis after making those changes. Am I going about this the wrong way? Any help is appreciated.

  • LSI RAID-on-chip with RAID6 over two SAS links goes red when HDD enclosure is powered cycled; how to recover?

    - by GregC
    I have a RAID6 array managed by LSI 9286-8e card. I also have Sans Digital 24-bay NexentaSTOR JBOD enclosure with SAS extender built-in. They are connected to separate UPS devices. Normally, I'd shut down the PC, leaving RAID6 in healthy state. But today the power to JBOD enclosure was cut but PC kept running. After restarting the PC, all disks in RAID6 have lit up RED, and the only option in LSI MegaRAID manager app was to reset each disk to unassigned, thereby loosing all data on RAID6 array. Thankfully, I am only testing, but how would I recover if this were to happen in production?

  • Computer starts, POSTs normal, no video

    - by Annath
    So, I recently tried to start up an old computer of mine. It would not power on, so I replaced the PSU. When I powered it on, all the fans spun up and the POST beeps indicated a normal startup. The problem was there was no video output. Every couple of minutes, I hear the post code again. I think it is restarting after POST, but without video I have no idea why. Does anyone have an idea as to why this is happening, and how to fix it? EDIT: The video card is a PCI-e card. There is no integrated graphics on the motherboard. If I remove the video card, the POST indicates a missing card. When I put it back, it goes back to normal, so I know that it recognizes that the card exists.

  • Restore monitor detection to one only or restore start menu to bottom [Windows 7]

    - by Mark
    I have a co-worker that is no longer able to see his start menu. He used to have it pinned to the left edge of his screen. I tried to troubleshoot it a bit and discovered if we do Windows + R then "cmd" [enter] the command prompt opens (but we don't see the start menu or run box), meaning the start menu is somewhere, just off screen. Restarting doesn't help. Is there some way to force Windows to think it only has a single monitor? It seems to "think" it has two but there's only one and we can get the Start menu back. Or, is there a way to restore the start menu to the bottom? Additional info We are able to right-click the desktop for display settings, etc. We can also get into Windows Explorer (via Ctrl + E) so if we need any of that to restore settings we can do it.

  • User profile and desktop unclickable and unviewable from windows explorer

    - by Abel
    Situation: Windows Vista, latest updates. After restarting to complete an installation, I find myself looking at a totally black windows desktop without any icons. The start menu and taskbar, including quickstart icons, appears. Some, but not all task bar tray icons appear. The systems seems stable. When I open Windows Explorer and click "desktop" in the folder treeview, the cursor immediately jumps back to the previously selected item. No error. Same when clicking on my user's profile or my documents. When I try "save as" in, say, Notepad, nothing happens, the dialog box (which defaults to "my documents") doesn't even show. Again, no error. Nothing serious afaict in the event log. Typing something Start Search shows "Search failed to initialize". Anybody ever encountered such abomination?

  • How to interpret output from Linux 'top' command?

    - by Ali
    Following a discussion made HERE about how PHP-FPM consuming memory, I just found a problem in reading the memory in top command. Here is a screenshot of my top just after restarting PHP-FPM. Everything is normal: about 20 PHP-FPM processes, each consuming 5.5MB memory (0.3% of total). Here is the aged server right before restart of PHP-FPM (one day after the previous restart). Here, we still have about 25 PHP-FPM with double memory usage (10MB indicating 0.5% of total). Thus, the total memory used should be 600-700 MB. Then, why 1.6GB memory has been used?

  • Mysterious gray square outlines on certain desktop icons?

    - by user74757
    Recently, my hand slipped on my mouse/keyboard and I accidentally increased the icon size. After resetting it and fixing them, I noticed these incredibly annoying small gray outlines around only certain desktop icons. I have one third party program called 'Desktop Restore' that I use to save and restore icon layouts, but I have no reason to believe that it should have anything to do with it. My question is: Is this something in Windows 7? If so, what is it there for and how can I turn it off? Killing explorer.exe and restarting it doesn't fix the problem, not even rebooting...

  • PC reboots automatically in the begining

    I have a AMD Phenom II 3GHz. 2 GB RAM system running on Windows 7. Off late my PC does not start properly I have to start it at least 7-8 times before it starts. It starts and then shuts down. Every time the time for which the system is up increases. After 7-8 attempts it starts an works fine. I have to give it a min between restarts (USB mouse light goes off). If I try restarting before this time the PC does not start. I am suspecting humidity playing some factor as this issue has started creeping up ever since the rains have started.

  • How to get diagnostic information on a failing Windows Server 2012 install

    - by Tobius Maximus
    I am trying to install a copy of Windows Server 2012 on two machines. Both machines go through the initial "Files loading" progress bar and get to the new Windows Server 2012 logo. However, the installation (on both machines) will immediately fail, and the machine will restart. I am trying to figure out if there's a way to display diagnostic information about the error before or after restarting, but Google is not helping me at all. Is there a key combination I can hit that will display an error log, perhaps?

  • How to use supervisord to run a PHP script as a daemon?

    - by Alasdair
    I need to have 8 threads of the same PHP script running in the background on a server continuously (as a daemon), and each script need to be automatically restarted if it exits for any reason. I've been advised to use supervisord to do this, but I don't at all understand their documentation, which seems very complicated to me. I also want each of the 8 threads of the script to be initially started at 2 minute intervals (2 minutes in between each launch) but then after this all 8 threads of the same PHP script should continue running on the server forever (and restarting if any exit for any reason). Could someone please explain how to do this with supervisord, or any other easy way of doing it? I'm on CentOS 6. Thank you!

  • MacBook's Airport not working from menu bar

    - by not22
    All of the sudden my MacBook doesn't connect to my wireless after waking from sleep. My network shows up at full signal strength and it remembers the password correctly, but I get an error message when I try to connect from the menu bar. The only way I can get on the internet is to go through Network Diagnostics and turn it on there. I don't understand why it works every time through Network Diagnostics and never on it's own or through the airport menu bar. Nothing has been changed or installed or reset on my computer that I know of. Restarting doesn't fix it, nor does turning off the airport card. Any ideas?

(II) XINPUT: Adding extended input device "Synaptics Touchpad" (type: TOUCHPAD) (--) Synaptics Touchpad: touchpad found # { rmmod psmouse && echo mem /sys/power/state && modprobe psmouse; } (WW) : No Device specified, looking for one... (II) : Setting Device option to "/dev/input/mice" ... How to tell X.org to try it's InputDevice again (without restarting X server)? P.S. rmmod psmouse is needed to prevent crashing of Acer Extensa 5220 when resuming from suspend-to-ram. Update: Found answer myself: Doing xinput set-int-prop "Synaptics Touchpad" "Device Enabled" 8 1 after reloading the kernel module reloads touchpad. Now suspend-to-ram works OK.
