• Limiting memory usage and mimimizing swap thrashing on Unix / Linux

  - by camelccc

  I have a few machines that I machine that I use for running large numbers of jobs where I try to limit the number of jobs so as not to exceed the available RAM of the machine. Occasionally I mis-estimate how much memory some of the jobs will take, and the machine starts thrashing the swap file. I resolve this by sending the kill -s STOP to one of the jobs so that it can get swapped out. Does anyone know of a utility that will monitor a server for processes by a specific name, and then pause the one with the smallest memory footprint is the total memory consumption reaches a desired threshold so that the larger ones can run and complete with a minimum of swap file thrashing? Paused processes then need to be resumed once some existing processes have completed.

• How to setup a daily report of the top e-mail senders in Exchange 2010

  - by Belmin

  We have had issues with compromised Exchange accounts sending a large amount of unsolicited e-mails out. We have mitigated this by using a cloud e-mail gateway that does a better job in detecting these outgoing messages as to not hurt our e-mail reputation. However, we would still like to detect any abnormal e-mail activities. One idea is a report of the Exchange accounts with the most outgoing message. Any idea on how to do this? Or a similar stat that may be indicative of an account being compromised?

• Windows 8.1 keeps prompting for Network Share Credentials after every log on or restart

  - by Peret del Trunfa

  I have a Network drive Shared in a Workgroup with 3 clients. Two clients with Windows 7 have persistent connections to the Share. No issues with those two. My windows 8.1 client keeps prompting for credentials at every restart / log on. I spent hours looking around for a solution: I have stored cred in cred manager, and tried every possible combination (WORKGROUP\user , COMPUTERNAME\user, user, .. and so on). I have changed NT and NTLM negotiation in policy manager. I've compared the settings under GPO network security with a working win 7 computer, everything is pretty much the same. -I've captured Wireshark to see SMB negotiation process, honestly I see the messages flowing around, and the share sending AUTH DENIED.. which means is how the 8.1 client formats the request.... that makes the share reject it.. Now I still don't really know why. Any ideas would be appreciated.

• What maintenance is required for a Postfix setup?

  - by JonLim

  I've taken a look at the setup and configuration process for a Postfix server, planning to use it for just sending emails out from my server. So far, I have these steps: Setup Postfix Configure Postfix Install DKIM Set SPF records Tune for performance Debug Seems rather straightforward. However, I was just wondering: are there any actions I should be taking for periodic maintenance of my Postfix setup? Thanks! EDIT: Also, just curious, how long would this entire setup ideally take? 30 - 60 minutes? More?

• Will this SPF record restrict delivery of email for the original domain?

  - by user199421

  As part of the product we offer we send emails on behalf of our clients. Because the emails don't come from an IP associated with the client they are sometimes flagged as spam. We advised some of our clients to add an SPF record approving us to send emails on their behalf. We saw immediate improvement in deliverability rates after making the change however one of our clients was notified by his hosting provider that the SPF record we suggested to add would "slightly restrict" all emails that don't come from our servers (including our client's own servers). The record we use is this: v=spf1 a mx include:ourdomain.com ~all So my question is if the warning we received about this is correct and if so why and what can be done to solve this (allow sending email both from original domain and by ourselves).

• Postfix - How to process incoming emails?

  - by Borivojevic

  Hello Does anybody know how to process incoming emails for virtual mailboxes in postfix? I am building web application where users add new content by sending emails to application. Email address used for each user is custom (eg. [email protected]) and it is dynamically created as a Postfix virtual mailbox. User needs to be able to send email to his custom mailbox address ([email protected]) and i want to process each incoming email, parse it's contents and populate my database with data from email. I tried using Postfix After Queue filter but what i really wont is to process emails once they are saved in users virtual mailbox folder.

• Best way to "stream" music / video to my HDTV from my pc?

  - by loj

  My requirement is simple: I have a laptop and a desktop at home that I often use for various media (music, videos etc.) and I want to know what the best (quickest, most seamless, best quality etc) solution for sending this media to my HDTV (and connected sound system). An example would be I'm listening to some music from youtube on my laptop in my living room and want to quickly send it to my tv (which has a sound system) so that I don't have to listen to it through my laptop. I mainly use linux (but a windows dependent solution would be ok too if its the best option). I would greatly appreciate any suggestions. Oh and a wireless solution would be best.

• Solution to: Hotmail Senders receiving NDR : “550-Please turn on SMTP Authentication in your mail client…”

  - by Tony Yustein

  Original question is here original question I can not answer to that question because the system requires me to have 10 credits, very nice.... This error is based mostly on mobile devices, mostly on iPhones and mostly on mobile networks. This is how much I have narrowed it to. I believe: Hotmail checks where your are connecting from If it is a mobile network it requires additional security for sending messages but the default iPhone config does not have this option for hotmail if the user creates the hotmail account on the iPhone with SMTP AUTH enabled manually it might solve the situation Cheers, Tony

• CSMA between APs in same channel & different SSID ?

  - by Ranganathan

  Would be great if someone clarifies this doubt. Lets assume two Wireless Access Points AP1 & AP2 with these conditions 1. both in the same 802.11 standard 2. same channel 3. using different SSIDs (just like in adjacent apartment houses). In this case, do these two Access points (and the clients associated to them) coordinate via CSMA/CA ? ie., if one of the AP's or a client station is about to transmit, does it wait & observe the other AP's & its clients' transmission before sending the frame in air ? Also, do the clients associated with these different APs coordinate via CSMA/CA ?

• Apache Bench length failures

  - by Laurens

  I am running Apache Bench against a Ruby on Rails XML-RPC web service that is running on Passenger via mod_passenger. All is fine when I run 1000 requests without concurrency. Bench indicates that all requests successfully complete with no failures. When I run Bench again with a concurrency level of 2, however, requests start to fail due to content length. I am seeing failures rates of 70-80% when using concurrency. This should not happen. The requests I am sending to the web service should always results in the same response. I have used cURL to verify that this is in fact the case. My Rails log is not showing any errors as well so I am curious to see what content Bench actually received and interpreted as a failure. Is there any way to print these failures?

• Recently used contacts getting corrupted Outlook 2010

  - by advis12

  We are using Microsoft's Identity Integration Feature Pack to sync contacts between two separate domains at two separate branches of our company. Recently we have run into an issue with a few of the contacts being pulled/synced from this remote location. When people in our organizaion are sending emails to certain contacts that are being synced from the remote location, the message delivery fails. After looking into the issue we are seeing that this failure is the result of the email being sent to some obscure email address rather than the correct email address. For example, the email address is getting changed to IMCEAEX_O=NT5_ou=44C5AE1BBEE0ED499F607407769311BB_cn=2F31FA0CA187314FA8D6A99BEFC52C36@domain.com rather than [email protected] Clearing the recently used contact list seems to solve the issue, but it does not solve the underlying problem. Because this issue is starting to happen to several different people I would like to solve the underlying cause. Does anyone have any input on how to start troubleshooting this issue? Also, we are using Exchange 2010. Thank you for taking the time to look at this.

• What can cause a black or blank screen when pressing logout or switch user in windows 7

  - by Medran

  The situation I have here is related to a brand new dell machine with a GTX260 video card. Put simply after one user logs in when that user either 'switch users' or 'logs out' windows goes to a black/blank screen. The TV screen that is used with this computer previously functioned fine with fast user switching on an XP machine. The new computer is windows 7. The TV is not outputting any error messages like 'no signal' or anything else that would be displayed if the computer was off. You can fix the problem by cycling the input on television, after cycling the input the welcome screen appears as normal. What I want to know is what on earth is windows doing that would cause the video card to stop sending the same signal to the monitor when the user logs off or switches users. I mean as far as I can tell the resolution is identical between windows and the welcome screen. Or perhaps if somebody has experienced this before a fix would be great too.

• Why do I see different TCP behaviour between IIS and FTP server applications on Windows 2003?

  - by rupello

  I am comparing Wireshark traces of a 10MB file download file from: the FileZilla FTP server and IIS (using HTTP) on the same Windows 2003 server. The FTP download performs faster and the trace shows the server behaving as expected, sending more data to the client with every ACK received: Link to full-size image The HTTP server trace shows a more bursty pattern. The timing of the send bursts are sometimes unrelated to any ACKs received from the client (circled in red): Link to full-size image Anyone have a suggestion as to why IIS traffic is having like this? Update: We have tried modifying the http.sys registry settings (setting MaxBytesPerSend to 256k and MaxBufferedSendBytes to 64k as recommended). Changing MaxBytesPerSend does seem to improve performance by increasing the amount of in-flight data , but we still see the same bursty pattern.

• MPICH2 vs KERRYGHED

  - by user40135

  Hi All right now I am moving first steps in clustering. I installed MPICH2 on my Ubuntu at home and I have a silly question about it. For what I am reading right now it seems that it provides the capability of sending processes to other pcs. I went for this lib just because I set it up very quickly and easily. Compared to MPICH2 , do you know what is the advantage of having a different clustering system like KERRYGHED? It seems that these ones also provide this capability, but the Kernel must be rebuild, so I suppose that it is going to be faster. What other advantages are remarkable for a clustering system like this? Thanks

• Best 'free' option for alert notifications other than email/SMS

  - by Eureka Ikara

  Looking for a Linux script solution that can send alerts to a service such as Twitter, Skype or Google Talk and sends to Android and iPhone clients. Have found twurl for Twitter with previous Bash scripts using curl no longer supported. But twurl looks promising. But haven't seen how to get Android Twitter client to make a distinctive sound when a tweet arrives. Found some info about Skype4Py from several years ago that supports Skype Chats. But doesn't look like it is currently supported. Have tried a few CLI clients for XMPP/Google Talk including xmpp4r-simple and freetalk, but found xmpp4r-simple buggy and freetalk succeeded in sending one chat message, but most never arrived. Whatever is used needs to support Android and iPhone clients. Reason why email is problematic is that Gmail gets very upset when emails start flooding in every minute as a result of alerts. Any suggestions?

• how to monitor traffic at port 53 (DNS)

  - by Registered User

  I am a bit confused with the abundant tcpdump tutorials on internet. I am having a few of the virtual machines running on a virtualization server.Where I am debugging a problem.Port 53 is the one in problem. I have a bridged setup where out of 4 LAN cards on the machine in question one is active and it is xen-br0 I want to check if there is any request coming on port 53 on the server by other machines on LAN in question. I also want to see if the guest operating systems on LAN or any other machine is sending traffic at port 53.Due to abundant messages being generated via tcpdump I am finding it difficult to grep the output at desired port. So how can I use it if some one can give an example that would be helpful. Thanks in advance.

• Changed domain A records for new static ip, but no mail

  - by Tim the Enchanter

  We have recently changed our ISP, I have changed the mail and mailserver DNS A records for our domain name to point to the new external static IP address assigned to the router by the new ISP (the MX record points to mail.<mydomain> as always) but I am not getting any email (though sending email works). Do I just have to wait will the change propagates? I am slightly concerned because I can connect to the web email service made visible through the new router which suggests that the mail.<mydomain> static I.P. address change has happened. Have I missed something?

• Queue emails under linux

  - by md1337

  I have a slow distant mail relay server and a web application I'm using locks up when sending e-mails to that distant mail server, until the e-mail is sent. After the e-mail is sent the page comes back and the application is snappy again. SO I'm trying to set up a differed mail queue locally on the application server (linux) so that the application uses that instead of the distant mail server. My rationale is that e-mails would get queued up locally until they are processed by the distant mail server, but at least the application doesn't lock up. I have installed postfix and set up the relayhost setting to the distant mail server, but performance has not improved. What appears to happen is that postfix just forwards my SMTP instructions in real time and doesn't really queue them? What can I do? Thanks!

• OS X Leopard (10.5) Server -- Unwanted Emails

  - by David

  Our OS X Leopard (10.5) server is sending out an email EVERY DAY for a Disk Full Notification on an external HDD we use for Time Machine backups (which manages it's own disk space, so the disk full notifications are useless). In the Server Admin app, under Settings Notifications, there's this: which is clearly disabled. The email header and message: http://pastebin.com/V5PZ3Phk I've been told to check the mail.log, but it's mostly empty (except for a few logs in 2011 saying "Postfix mail system is not running". I've also been told to check the crontabs, but I'm not sure how to do that on OS X (or any OS for that matter). Can someone explain how to do this? Also, if there's any other suggestions on places/things/etc to look at/for, my ears are all open!

• How to achieve in-folder discussions with IMAP (skip SMTP send, Thunderbird)?

  - by lkraav

  Does anyone know a good way to achieve replying to a message into the same IMAP folder without sending another duplicate copy over SMTP? This is to be achieved with a conventional GUI mail client, especially Thunderbird. Goal is to have an in-folder conversation. This is possible with shared IMAP folders, with per-user Seen indices, where subscribed recipients are guaranteed to see the new messages without them arriving from internet. Thunderbird is capable of storing a copy of a reply in the same folder as original message (Account Options), which is half way there. Just pressing Save sends the message into Drafts and that is probably an even bigger patch to try to put a "draft message" into the same folder as original. All options, client, server or logic-wise are an acceptable answer, including programming i.e. patching/creating add-on for Thunderbird.

• Asterisk Register username with special character like "@"

  - by Najibul Huq

  I am using a SIP provider that has provided me with a username like: [email protected] (Note this is only the username part) And has a numerical password. My Register string looks something like this: [email protected]:[email protected] But this is not working, as asterisk is only sending the first part +112223344 before the first @. My provider is adamant about having the full form of it. This is the first time I am facing this issue that is quite unusual for me. Please help.

• Firefox unable to load SSL Certificate Chain, while Chrome, IE do

  - by FryBurger

  I created a certificate for our IIS 6 by sending a request (created with openssl) to our organization's CA. I already had trouble to integrate the private key into that certificate, that has been solved, see SO question IIS 6.0 now uses the certificate (with TSL v1 and SSL v3), that is the 4th in cert hierarchy. Now, if I access the intranet site, chrome accepts the certificate, so does IE, but Firefox complains about an insecure connection and wants me to add an exceptional rule. If I look into the certificate, how FF presents it to me, I cannot see any of the three issuers. How can this be? If I connect via openssl s_client -showcerts -connect... I only see my own certificate too, which is said to be not verified. I am quite confused now. Where's the mistake and how can I make FF accept certificate without forcing our users to add that exceptionrule? Maybe do I have to add all the three issuer certificates into cert store of the win2003 server that hosts IIS 6.0 ??

• How I can view and block specific applications temporarily from accessing Internet?

  - by Curious Apprentice

  I don't want to block any application permanently from accessing internet. I just want to block some specific applications for a particular time period to gain speed in running some other. I know about one such great tool - that is "Comodo firewall". It can smoothly block and accurately display apps accessing internet. The only problem of installing this is, Windows recommends only one firewall apps and as Im running Windows 7 x64 Ultimate there will be complications if I install this one. I need a tool which can accurately display which apps are accessing internet (through which port) and how much data they are receiving or sending. I also need some arrangement within the app so that I can easily temporarily block that app from accessing internet.

• Squid 2.7.6 not honoring ACL rules

  - by peppery

  Hello there, I have a /24 block of IP addresses assigned to a single server that I have been attempting to install Squid on an Ubuntu server machine. All of the IP addresses are set up correctly (aliases of eth0) in /etc/networking and work as they should be, using cURL I can specify an interface and it goes out on the correct address as it should be. I would like Squid to take the incoming IP address the request was sourced to and proxy the request out on the same IP (e.g incoming 123.123.123.1:3128 - 123.123.123.1, .2 - .2, etc) and have set up these ACL rules in /etc/squid.conf acl ip1 myip x.x.x.1 tcp_outgoing_address x.x.x.1 ip1 acl ip2 myip x.x.x.2 tcp_outgoing_address x.x.x.2 ip2 acl ip3 myip x.x.x.3 tcp_outgoing_address x.x.x.3 ip3 and so on, as this seems to be the only way to do what I want (from research). However, after much frustration, Squid seems to be ignoring these rules and sending requests out on the default interface. Does anybody have any suggestions? Thanks.
