  • `adduser [options] user group` fails ubuntu 11.04

    - by Rob
    I'm want to use adduser However it doesn't seem to work if I provide the second argument for the user's group root@a:~# adduser rick staff adduser: The user `rick' does not exist. The group exists root@a:~# addgroup staff addgroup: The group `staff' already exists. The man page says this should work... adduser [options] user group Any ideas? I can do: adduser --ingroup staff rick So no massive issue, just seems strange.

    - by Saif Khan
    Hi, I have a PC, when the user sends an item it's stuck in the outbox after sending. The strange thing is that the mails are being sent to the recepient. It's just that Outlook doesn't move it from Outbox to Sent Items...I checked all the settings and all is well. This is a POP3 account. What else can I check?

  • can't send with postfix but I can whith one user

    - by CvR_XX
    I have a postfix and dovecot server but when i try to send an email i get an time -out. Im trying to send with the email [email protected]. A telnet session isn't helping much ether. I get a blank screen. Local it's working fine. My smtp service is running on treadity.com:25. The strange thing is that the logs are completely empty with any info regarding sending emails. Receiving is working alright. Another strange thing is that i've send some message's and that it worked. But that is only with one email. I can still send from that account but other emails are failing any idea's? config file: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

  • All internet requests in Windows time out

    - by Brandon
    So, I've run into a very strange problem with my home wireless network. Previously, at seemingly random times, the router seemed to disconnect all wireless hosts and cause all of the wired hosts to have a "limited connection" according to windows. In order to fix this, I had to unplug all of the wired hosts from the router, unplug the modem from the router, and power cycle the router. This seemed to solve the problem for a while until the exact same thing happened a day later and I had to go through the same process again. That's where I noticed something weird happening. There was one wireless host (a Windows Vista laptop) that seemed to be causing the router to disconnect the other hosts whenever it connected. When this happened, only that laptop was able to use the wireless from the router. When this happened, I disconnected it from the wireless (by disabling the wireless adapter) then reconnected it (by re-enabling it) and now it, like the other hosts, couldn't connect. I've never really seen anything this strange happen on our network before. So, I restored the router to factory settings and the problem seems to have vanished except one crucial problem. There's another host (a Windows 7 laptop) that was perfectly able to connect before all of the router issues and even in between the crashing and power-cycling events but now says its connected and says it's able to reach the Internet, but all requests time out. In any browser I've tried, the tab says connecting to [site]... for a solid minute and then tells me the request timed out. When I try to ping google.com in cmd it also says request timed out. In frustration, I booted into a dual-boot Ubuntu installation on the Windows 7 host and the connection works fine, to my surprise, as ubuntu is where I am now typing this rather long question. I haven't looked through the event log in windows but will post anything I find in an edit I haven't tried connecting (in Windows 7) to any other wireless network, since The fact that it works in Ubuntu suggests its Windows and not the router but I didn't change any wireless settings in windows before it being able to reach the Internet and not. Does anyone have any clue what could have happened. I opened to buying another router as this one is almost a year old :) but I would like to know whats going on here. Thanks in Advance! P.S. Sorry for how long my question is, I'm a little anxious (:

  • Mailing List Application?

    - by marienbad
    Mailing lists are great, but they're a fundamentally different beast than email. It seems strange to me to keep mailing lists in my email program (Gmail). Of course I have folders set up to automatically keep them out of my inbox, but if I have hundreds of mailing lists, it gets really out of hand. Is there an application (or web application) that is designed specifically as a mailing list "client"?

  • How do I prevent TCP connection freezes over an OpenVPN network?

    - by Jason R
    New details added at the end of this question; it's possible that I'm zeroing in on the cause. I have a UDP OpenVPN-based VPN set up in tap mode (I need tap because I need the VPN to pass multicast packets, which doesn't seem to be possible with tun networks) with a handful of clients across the Internet. I've been experiencing frequent TCP connection freezes over the VPN. That is, I will establish a TCP connection (e.g. an SSH connection, but other protocols have similar issues), and at some point during the session, it seems that traffic will cease being transmitted over that TCP session. This seems to be related to points at which large data transfers occur, such as if I execute an ls command in an SSH session, or if I cat a long log file. Some Google searches turn up a number of answers like this previous one on Server Fault, indicating that the likely culprit is an MTU issue: that during periods of high traffic, the VPN is trying to send packets that get dropped somewhere in the pipes between the VPN endpoints. The above-linked answer suggests using the following OpenVPN configuration settings to mitigate the problem: fragment 1400 mssfix This should limit the MTU used on the VPN to 1400 bytes and fix the TCP maximum segment size to prevent the generation of any packets larger than that. This seems to mitigate the problem a bit, but I still frequently see the freezes. I've tried a number of sizes as arguments to the fragment directive: 1200, 1000, 576, all with similar results. I can't think of any strange network topology between the two ends that could trigger such a problem: the VPN server is running on a pfSense machine connected directly to the Internet, and my client is also connected directly to the Internet at another location. One other strange piece of the puzzle: if I run the tracepath utility, then that seems to band-aid the problem. A sample run looks like: [~]$ tracepath -n 192.168.100.91 1: 192.168.100.90 0.039ms pmtu 1500 1: 192.168.100.91 40.823ms reached 1: 192.168.100.91 19.846ms reached Resume: pmtu 1500 hops 1 back 64 The above run is between two clients on the VPN: I initiated the trace from 192.168.100.90 to the destination of 192.168.100.91. Both clients were configured with fragment 1200; mssfix; in an attempt to limit the MTU used on the link. The above results would seem to suggest that tracepath was able to detect a path MTU of 1500 bytes between the two clients. I would assume that it would be somewhat smaller due to the fragmentation settings specified in the OpenVPN configuration. I found that result somewhat strange. Even stranger, however: if I have a TCP connection in the stalled state (e.g. an SSH session with a directory listing that froze in the middle), then executing the tracepath command shown above causes the connection to start up again! I can't figure out any reasonable explanation for why this would be the case, but I feel like this might be pointing toward a solution to ultimately eradicate the problem. Does anyone have any recommendations for other things to try? Edit: I've come back and looked at this a bit further, and have found only more confounding information: I set the OpenVPN connection to fragment at 1400 bytes, as shown above. Then, I connected to the VPN from across the Internet and used Wireshark to look at the UDP packets that were sent to the VPN server while the stall occurred. None were greater than the specified 1400 byte count, so the fragmentation seems to be functioning properly. To verify that even a 1400-byte MTU would be sufficient, I pinged the VPN server using the following (Linux) command: ping <host> -s 1450 -M do This (I believe) sends a 1450-byte packet with fragmentation disabled (I at least verified that it didn't work if I set it to an obviously-too-large value like 1600 bytes). These seem to work just fine; I get replies back from the host with no issue. So, maybe this isn't an MTU issue at all. I'm just confused as to what else it might be! Edit 2: The rabbit hole just keeps getting deeper: I've now isolated the problem a bit more. It seems to be related to the exact OS that the VPN client uses. I have successfully duplicated the problem on at least three Ubuntu machines (versions 12.04 through 13.04). I can reliably duplicate an SSH connection freeze within a minute or so by just cat-ing a large log file. However, if I do the same test using a CentOS 6 machine as a client, then I don't see the problem! I've tested using the exact same OpenVPN client version as I was using on the Ubuntu machines. I can cat log files for hours without seeing the connection freeze. This seems to provide some insight as to the ultimate cause, but I'm just not sure what that insight is. I have examined the traffic over the VPN using Wireshark. I'm not a TCP expert, so I'm not sure what to make of the gory details, but the gist is that at some point, a UDP packet gets dropped due to the limited bandwidth of the Internet link, causing TCP retransmissions inside the VPN tunnel. On the CentOS client, these retransmissions occur properly and things move on happily. At some point with the Ubuntu clients, though, the remote end starts retransmitting the same TCP segment over and over (with the transmit delay increasing between each retransmission). The client sends what looks like a valid TCP ACK to each retransmission, but the remote end still continues to transmit the same TCP segment periodically. This extends ad infinitum and the connection stalls. My question here would be: Does anyone have any recommendations for how to troubleshoot and/or determine the root cause of the TCP issue? It's as if the remote end isn't accepting the ACK messages sent by the VPN client. One common difference between the CentOS node and the various Ubuntu releases is that Ubuntu has a much more recent Linux kernel version (from 3.2 in Ubuntu 12.04 to 3.8 in 13.04). A pointer to some new kernel bug maybe? I'm assuming that if that were so, then I wouldn't be the only one experiencing the problem; I don't think this seems like a particularly exotic setup.

  • Google Chrome: How do I get my status bar back?

    - by d03boy
    This silly design of the status bar popping up and disappearing is really bothering me. I used to have a few good extensions on my status bar in Firefox (Pagerank, AdBlock, etc) and now they all have to be placed in strange locations on the toolbars near the top without easily displaying any relevant information. Is there a way I can get the status bar back and use it similarly to FF?

  • Can not copy files from Windows 2003 server over network

    - by Mark
    It seemed quite strange. I have a share folder with full read/write permission on my Windows 2003 server. With a XP client, I can create a new folder on the share folder, and I can copy files to it normally, but I can not copy these files back to my client PC. I tried use ftp,and webdav to get the files from server. None of them worked. Is the issue related with NETWORK SERVICE? Thanks for your help.

  • Configure APC for maximum hit rate

    - by Steven De Groote
    I'm currently running php5 with APC, the latter with default configuration. However after setting up munin to monitor APC, I'm surprised by the results: apc.shm_size: 30 apc.gc_ttl: 3600 apc.ttl: 0 Used: 14MB Request rate: 100 requests/second Fragmentation: 0 Hit ratio: 80% (dropping to 0 a few times per hour) So the obvious question: how can I adapt the configuration to achieve a higher hitrate. I find it very strange that the available memory is not fully used which the hitratio is still below what I would expect. Thank for any hints!

  • How to burn a 8.5GB ISO?

    - by Vilx-
    I have an ISO image of a DVD which is 8.5GB in size. I find this strange, because that is about 500MB more than a standard DL DVD can hold. I tried overburning with Nero, but it failed. Is it possible to somehow burn such an image? Are there some special DVD blanks that allow you to write more? Or is this ISO simply made by some tool without any regards of whether it can be burned or not?

    - by Gregory MOUSSAT
    I have a Windows 7 computer which have a strange behavior: when preview is enabled in explorer, I double-click on any Word document, Word is launched, the document is loaded, and immediatly explorer is in the foreground window (so Word is in the background). The whole process take less than one second. Only with Word. Not Excel or anything. Only on one computer (5 others are identical and installed the same day).

  • Postrouting rule in NAT table

    - by codingfreak
    Hi I have a strange question regarding NAT using iptables. When I do SNAT in a postrouting chain in NAT table at the end of the rule should I give -J ACCEPT? I see counters on the postrouting rule getting incremented but no packet leaving the machine. So does it mean the packet is DROPPED automatically?

  • Word 2007 Document Properties (gone wrong)

    - by Nippysaurus
    I have copied a document which contains some properties which are displayed in fields in the text. Specifically the "Subject" property. If I update the properties in "Menu Prepare Properties", then navigate to the field in my document, right-click it and select "Update Field", I would expect the field in my document to be updated with the new value that was entered in the menu, but the opposite is happening. Is there some strange voodoo going on here?

  • DVD-Player "Simulation"

    - by SjoerdV
    This may sound like a strange question, but I was wondering if there is software available which can emulate the behaviour of standalone dvd-players. I'm currently debugging a DVD we're creating, and I can't afford to go hopping to my house every time to check. The reason I'm asking is because the problems just appear on 'some' dvd-players which I cannot predict. Other option maybe, is there software that can check a VIDEO_TS folder or iso file for errors?

  • Missing pictures in folder

    - by Pablo Fernandez
    I had a folder with some pictures, somehow these pictures are "missing" and I cannot see them anymore. The strange thing is that if I use the "preview" view in Explorer (the one that shows the tiny icons of the folder contents), the folder preview shows these pictures as if they were inside. Once I enter the folder, they are not there anymore. I tried showing hidden files and folders, that doesn't help. Any ideas on how to show or recover those files? I'm using Windows XP.

  • Mysterious visitor to hidden PHP page

    - by B. VB.
    On my website, I have a "hidden" page that displays a list of the most recent visitors. There exist no links at all to this single PHP page, and, theoretically, only I know of its existence. I check it many times per day to see what new hits I have. However, about once a week, I get a hit from a 208.80.194.* address on this supposedly hidden page (it records hits to itself). The strange thing is this: this mysterious person/bot does not visit any other page on my site. Not the public PHP pages, but only this hidden page that prints the visitors. It's always a single hit, and the HTTP_REFERER is blank. The other data is always some variation of Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; YPC 3.2.0; FunWebProducts; .NET CLR 1.1.4322; SpamBlockerUtility 4.8.4; yplus 5.1.04b) ... but sometimes MSIE 6.0 instead of 7, and various other plug ins. The browser is different every time, as with the lowest-order bits of the address. And it's just that. One hit per week or so, to that one page. Absolutely no other pages are touched by this mysterious vistor. Doing a whois on that IP address showed it's from the new york area, and from the "Websense" ISP. The lowest order 8 bits of their address are always different, but always from 208.80.194.*/8. From most of the computers that I access my website, doing a tracerout to my server does not contain a router anywhere along the way with the IP 208.80.*. So that rules out any kind of HTTP sniffing, I might think. I have NO idea how, why this is happening. Does anyone have any clue, or have seen something as strange as this before? It seems completely benign, but unexplainable and a little creepy. Thanks in advance!
