  • Postfix not delivering mails

    - by Sotocan
    I have problems with a recently configured postfix MTA. When postfix starts the following warning appears: "postfix/qmgr[5078]: warning: connect to transport private/filter: No such file or directory" I have amavis-new as a content-filter, but even if I comment-out the relevant line, the warning appears. As a result (I think), of the above, I get errors like below, for every virtual domain that I have: "postfix/error[5080]: 254851834107: to=, relay=none, delay=13082, delays=13082/0.01/0/0.01, dsn=4.3.0, status=deferred (mail transport unavailable)" The good news for me, is that somehow I managed to fix that (don't ask me how!!!!) The problem is that now I have 50 or so mails, that were affected by the aforementioned problem, in the mail-queue... If I "postqueue -f " I get the same style of error as before (mail transport unavailable)...however new mails are delivered to their final destination properly... Any suggestions? Kind regards. P.S. Local mail delivery from/to Unix and virtual users, was OK write from the beginning!

  • SSH from Windows Vista to Ubuntu (using cwrsync)

    - by user39141
    Newbie questoin but I can't seem to figure it out. Using cwrsync which in turn calls ssh.exe from a Windows Vista box to Ubuntu. For below, user in ubuntu is 'linuxuser' and user on Windows box is 'winuser' - remote box is 'linuxhost' and windows box is 'winhost' Exported keys such that on the remote box /home/linuxuser/.ssh/authorized_keys is correctly populated. Problem is when I launch ssh it tries to write to /home/winuser/.ssh instead of /cygdrive/home/users/winuser/.ssh as below. c:\Program Files (x86)\cwRsync\binssh linuxuser@linuxhost Could not create directory '/home/winuser/.ssh'. The authenticity of host 'linuxhost (192.168.1.105)' can't be establish ed. RSA key fingerprint is 67:10:a9:49:6e:a3:2b:4a:a0:e0:b7:75:76:da:c3:04. Are you sure you want to continue connecting (yes/no)? Host key verification failed.

  • Unable to access my own websites from our home

    - by user2521866
    Not sure if this is the right place to ask, but i'm gonna have a shot at it. I host a couple of websites with a webhost in the Netherlands. For a couple of days now, i've been unable to connect to them from my home network. When using tracert in the cmd screen, i'm getting a timeout after about 4-5 hops. It seems fine accessing the website from anywhere, except my home network. Other PC's around the house also fail to open the websites. I've tried 'flushing my DNS' as seen in some other topics, but to no avail just yet. One of the websites: http://bit.ly/1hbqs4J I've contacted my host about it as well, but no response yet. Trying to take control of the situation myself now for as much as I can. Regards, Dave

  • Cannot use `su` or `sudo` after set up key-based access to SSH

    - by OrangeTux
    I'm following this tuturial to setup key-based access to the SSH I created a user. I add copy the key to the client via ssh-copy-id <username>@<host> Becasuse ssh <username>@<host> still prompts for a password I run ssh-add on the local machine. The terminal doens't prompt for a password, I can login without using a password. But I cannot run su anymore. Every input for the password results in Authentication failure. I tried it again. But before coping the key, I added to the sudoer file. Copied key, ssh-add. But now I cannot login to my SSH shell att all? How can I setup a key-based SSH access with the possibiluty to use su or sudo?

  • What router hardware or software should be used when multiple public IPs are routed into the same LAN?

    - by lcbrevard
    I am looking for recommendations to replace a set of consumer grade (Linksys, Netgear, Belkin) routers with something that can handle more traffic while routing more than one static public IP into the same LAN address space. We have a block of static public IPs, 5 usable, with Comcast Business. Currently four of them are in use for: General office access Web server Mail and DNS servers Download and backup web server for separate business All systems (a mixture of physical and virtual) are in the same LAN address space (10.x.y.0/24) to enable easy access between them inside the office. There are 30 or more systems in use depending on which virtual machines are currently active. We have a mixture of Windows, Linux, FreeBSD, and Solaris. Currently a separate consumer grade router is used for each of the four static addresses, with its WAN address set to the specific static address and a different gateway address for each: uses 10.x.y.1 - various ports are forwarded to various LAN IPs on systems with gateway 10.x.y.1 uses 10.x.y.254 - port 80 is forwarded to a server with gateway 10.x.y.254 uses 10.x.y.253 - ports for mail and dns are forwarded to a server with gateway 10.x.y.253 uses 10.x.y.252 - ports as needed are forwarded to server with gateway 10.x.y.252 Only router 1. is allowed to serve DHCP and address reservation based on the MAC is used for most of the internal "server" IP addresses so they are at fixed values. [Some are set static due to limitations in the address reservation capabilities of router 1.] And, yes, this really does work! But... I am looking for: better DHCP with more capable address reservation higher capacity so I don't have to periodically power cycle the routers One obvious improvement would be to have a real DHCP server and not use a consumer grade router for that purpose. I am torn between buying a "professional" router such as Cisco or Juniper or Sonic Wall verus learning to configure some spare hardware to perform this function. The price goes up extremely rapidly with capabilities for commercial routers! Worse, some routers require licensing based on the number of clients - a disaster in our environment with so many virtual machines. Sorry for such a long posting but I am getting tired of having to power cycle routers and deal with shifting IP addresses afterwards!

  • Windows 7 pagefile size with large RAM and SSD

    - by Avi
    I've just upgraded my Windows 7 machine from 12GB to 24GB - both for running more VMs and for future proofing. My C driver is an SSD with 129GB formatted size. I was surprised to find out that the SSD only has 68GB free (most of my files are on D: to G:). Researching I found 24GB of my precious C: SSD are taken for virtual memory. So - do I need such large amounts of virtual memory when I have 24GB or RAM? I bought this size of memory so I"d not have to go to disk...

  • Can't access the Internet in VMware Workstation

    - by asunnysunday
    I'm using VMware 7.1.2 in Windows 7 with Ubuntu 11.04 as a guest OS. In the host OS (Windows 7), I can access the Internet without any problems but in the virtual machine I can't access the Internet. I've tried the following but with no success: Use all methods of connecting to the Internet in "Virtual Machine Settings": Bridged, NAT, Custom; none work. Used cabled and wireless connections on the PC - neither of them work. I've used Ubuntu in VMware for several months - previously the Internet was always accessible. Could the cause of this be because I upgraded to Ubuntu 11.04?

  • Small footprint on a Laptop

    - by sqldebacle
    I am trying to find a solution where I can do the following: 1) Run a small footprint on my laptop 2) Run virtual instances of OS w/ no primary OS installed. All the OS that I will ever use will be all virtualized. I tried playing around with the VMware Esxi, and got it to boot it from the flash drive, etc. But this just runs the server. I cannot actually run my virtual instances from there. Anyone has done this? Something similar implemented with VMWare products without needing 2 computers will be great. Thanks, -Subhash

  • Program keeping encrypted files.

    - by Giorgi
    I am looking for a program which will encrypt files specified by me and allow me to view/edit/delete those files without creating a virtual disk. I do not want to have virtual disk as a domain administrator can access it so truecrypt is not the possibility. One possibility is to use winrar with password protected archive but winrar serves a different goal so it is not very user friendly for this purpose. If it's possible it would be nice if the program does not creates temp files while I open the files. Any suggestions?

  • Network Monitoring Tool Recommendation

    - by user42801
    Hello, My company is looking for a monitoring app/tool that would allow us to capture and graph statistics on network performance. As a starting point, we would like to ping remote host(s) and gateway(s) from several of our servers, grab an average of the ping times from each of our servers to the remote host(s), and then graph it (preferably in a central location). Also, we would like to be able to graph the results for time frames as short as a week to as long as 6 months. It is reasonable to expect that we would ask more of the selected monitoring app/tool as we come up with other key network performance indicators in the future. So an app with great flexibility and features would be ideal. Upon first glance, Cacti looks like it might be a fit. Any other recommendations? Thanks in advance for any input.

  • Can I copy from vim to another window without +xterm-clipboard?

    - by GorillaSandwich
    I'm using Ubuntu and vim. I can copy text from vim and paste it into another window by highlighting it in vim, then middle-clicking in the other window. This works fine when I'm on my local machine. I can also copy into the system register by highlighting text and yanking to the system register. (For example, Shift-V JJ "+ y to go into linewise visual mode, highlight two lines, select the '+' register and yank.) It's then available to paste into other windows. However, if I ssh into my web host, I can't do either of these. (They use some flavor of Linux - I think it's CentOS.) In vim, if I type :version, my local version shows +xterm_clipboard, but the host's version shows -xterm_clipboard. I don't have sudo rights there. Is there any way to be able to copy from their vim without getting them to tinker with the installation?

  • Replace Certificate using Plesk 11

    - by Lambda Dusk
    I am not an admin, but a programmer. But how it is, if you're the only guy who knows about computers, everyone shoves those tasks to you. A certificate of a domain recently expired. The domains are managed using Plesk 11, on a Linux system, Apache2.2. I was given a new certificate from the host, and it is one single .pem file. However, Plesk asks me for a .crt file, a private key and some CA file. I have neither, only this single .pem file the host claims to be the certificate. Since I myself never did anything with SSL certificates, I would really appreciate if anyone can tell me what to do with this file and how to properly add a new one so the old one can be removed.

  • Mail Stuck in Backend Exchange Queue

    - by Kyle Brandt
    I have a message that has and is stuck in a queue on my backend mail server. The queue is: Internet Mail SMTP Connector (MY_FRONT_END_SERVER_NAME)-524350ff... It is in state retry with 183 failures. It is only one message and all other mail is flowing. The message is not particularly large. My limited understanding, a guess really, is that this message should get handed off to the front end mail server and sent to the remote hosts for which it is destined, so it should even matter if the remote host is up. However, I can telnet to the smtp provider of that host. How can I find out why it is stuck in this queue, and can I force it out somehow (unfreeze doesn't help me)?

  • High CPU Steal percentage on Amazon EC2 Instance

    - by Aditya Patawari
    I am experiencing high CPU steal percentage in a Amazon EC2 large instance. I know it means that my virtual CPU is waiting on the real CPU of the machine for time. My question is that what can I do to reduce this percentage and get maximum out of the CPU? Steal percentage is consistently at 20%. System load crosses 10 when this happens. I have checked memory and network and I am sure that they are not the bottleneck. Is that normal for such environment? Also are there any system level optimization techniques for reducing steal percentage form the virtual instance? avg-cpu: %user %nice %system %iowait %steal %idle 52.38 0.00 8.23 0.00 21.21 18.18

  • Does nginx auth_basic work over HTTPS?

    - by monde_
    I've been trying to setup a password protected directory in a SSL website as follows: /etc/nginx/sites-available/default server { listen 443: ssl on; ssl_certificate /usr/certs/server.crt; ssl_certificate_key /usr/certs/server.key; server_name server1.example.com; root /var/www/example.com/htdocs/; index index.html; location /secure/ { auth_basic "Restricted"; auth_basic_user_file /var/www/example.com/.htpasswd; } } The problem is when I try to access the URL https://server1.example.com/secure/, I get a "404: Not Found" error page. My error.log shows the following error: 011/11/26 03:09:06 [error] 10913#0: *1 no user/password was provided for basic authentication, client: 192.168.0.24, server: server1.example.com, request: "GET /secure/ HTTP/1.1", host: "server1.example.com" However, I was able to setup password protected directories for a normal HTTP virtual host without any problems. Is it a problem with the config or something else?

  • Exclude pings from apache error logs (ran from PHP exec)

    - by fooraide
    Now, for a number of reasons I need to ping several hosts on a regular basis for a dashboard display. I use this PHP function to do it: function PingHost($strIpAddr) { exec(escapeshellcmd('ping -q -W 1 -c 1 '.$strIpAddr), $dataresult, $returnvar); if (substr($dataresult[4],0,3) == "rtt") { //We got a ping result, lets parse it. $arr = explode("/",$dataresult[4]); return ereg_replace(" ms","",$arr[4]); } elseif (substr($dataresult[3],35,16) == "100% packet loss") { //Host is down! return "Down"; } elseif ($returnvar == "2") { return "No DNS"; } } The problem is that whenever there is an unknown host, I will get an error logged to my apache error log (/var/log/apache/error.log). How would I go about disabling logs for this particular function ? Disabling logs in the vhost is not an option since logs for that vhost are relevant, just not the pings. Thanks,

  • How to setup a Linux machine to remotely use laptop screen as a second display?

    - by Ignas Limanauskas
    I am looking for a similar solution to MaxiVista, but for Linux (Ubuntu). I have an Ubuntu machine with just one display attached, but I also have a Windows laptop running a virtual machine with Ubuntu installed. I figured there must be a way to trick the main Ubuntu machine remotely use the virtual machine's display capabilities. After all, X11 does support forwarding and things like that. Any ideas how to do it using VNC? I saw some references to xdmx, but instructions so far are vague and do not seem to work on my machine(s).

  • Can a RAID 4 disk setup crash if only 1 hard disk fails?

    - by Steve Rodrigue
    I am a web developer. I have not much experience in hardware. For this reason, I use managed servers. This morning, one of the drives in our setup failed. However, the full site went down. I asked my web host what happened and he replied that the hard disk failed in such a way that the RAID controller couldn't work properly. The array was set up as RAID 4. Do you guys ever seen that before? Is it possible? Thanks for any help on this guys. I need to know if my web host is honest with me.

  • some questions about raid card

    - by cpps
    I have some questions about raid card. Use LSI MegaRAID® SAS 9260-8i raid card as a example. There is only two connection ports on the raid card, and they provide two cables that can connect 8 SAS/SATA storages. The document say it can connect "Maximum 32 drives per controller", I want to know how can I connect more than 8 hard disks with this card. Is that they say "Eight internal SATA+SAS ports" means they provide two cables which can connect 8 hard drives, but you can use other way to connect Maximum 32 drives? The other question. I see host bus adapter has raid integrated , so what is the difference between host bus adapter and raid card. Are they the same? I also know is SAS/SATA Expander's function only to connect more hard drives? Thanks in advance.
