• Load-balance with LAN and Wifi

  - by Synox

  I have a Mac, which runs Mac OSX 10.6 or Ubuntu 9.10 or Windows XP (Multiboot). Solution can be for any of the systems, whatever works better. I have two ISPs, one can be accessed via Wifi, one can be accessed via LAN. In OSX i can define the priority, which network to choose first. But what i wish to do is to load-balance with both networks. I don't want to buy extra hardware. I have some unused wifi routers if this would help. Compiling and configuring programms in linux is no problem for me. Thanks for any help.

• What is the correct term for the number of bits used by an operating system

  - by benc

  Recently, some discussions came up about 32 bit vs. 64 bit implementations of operating systems. While I was composing a message about this topic, I realized that I did not know if there was a correct term for the number of bits supported by an operating system. For example, various versions of Solaris and Linux have 32bit and 64bit releases. Is the distinction "architecture"? In my experience, that has referred to chip types (Intel vs. PPC). Is it a "release"? Typically, I think of a release as a version number a consistent feature set, that might run on different architectures. Maybe it is just "architecture", after all, even though a chip family might have used several different bit sizes over time, the chips themselves are different when you jump from 32bit to 64bit.

• SLA Violations - Compensation expectations and vague contracts

  - by llllxllll

  Tagging this as cautionary tale. I took over for an admin a year and a half ago, and reviewed the 3 year contract with our ISP. There were no specific SLA promises in the contract that I found, and have been meaning to review the contract with our rep. Of course, we had an outage this past week that resulted in almost four days of downtime !!!!! This involves eff-ups of epic proportions on our ISP's part and a telco they colocate with. Details can be provided. I am the network / systems / purchasing / and helpdesk at my company...and am willing to fight with the ISP. I also have more management that can get involved, including the name on the contract. First, if there are not concrete guarantees about compensation and downtime, we are screwed right? Two, if we want out of our contract, does anyone have experience going the legal route, and if so, who knows a lawyer? =)

• Not all of your nameservers are in different subnets. Single point of failure

  - by user2118559

  Using VPS hosting and dynadot (domain registrar) DNS. Checked domain name with http://www.intodns.com and get some warnings Different subnets WARNING: Not all of your nameservers are in different subnets and Different autonomous systems WARNING: Single point of failure As understand to avoid the warning must have second Ip4 address and both the addresses must point to different servers? If both Ip addresses point to the same server, it does not help? I mean each server has own Ip address. If one server down, then visitors can access website (files) on another server? Is this the reason why need more than one Ip? Tried to point website to 2 ip addresses and after some time get warning from uptimerobot Connection Timeout

• Why is APC (PHP Accelerator) Only caching apc.php?

  - by amvx

  I installed PHP5,APC and XDEBUGGER with the install script found here: Dreamhost PHP+APC Install Instructions/Script All systems seem to be working... except... I added the apc.php to see the caching stats of APC (GUI Interface), and it showed that only apc.php file was being cached despite having installed wordpress and prestashop under the same domain, installing and running those php scripts. I wonder if I did something wrong... but my php5 is running as a cgi/fastcgi. I think I might have read somewhere about there being some issue with this. Not sure. Any help is of coursed appreciated.

• Spiceworks versus Request Tracker?

  - by dmackey

  We currently utilize Request Tracker for help desk ticketing, we utilize Spiceworks for asset inventorying. I am pondering whether it might be worthwhile to move from RT to Spiceworks for help desk as well. Has anyone used both systems and can provide some insight into any benefits/problems with either system? Or has general philosophical reasons why one should use one solution over the other? Of course, RT is open source and Spiceworks is not - and usually this would be a major item for me - but since Spiceworks is free and takes community involvement fairly actively its not as major of a concern for me (personally).

• What is the EGG environment variable?

  - by Randall

  A user on our (openSuSE) linux systems attempted to run sudo, and triggered an alert. He has the environment variable EGG set - EGG=UH211åH1ÒH»ÿ/bin/shHÁSH211çH1ÀPWH211æ°;^O^Ej^A_j<X^O^EÉÃÿ This looks unusual to say the least. Is EGG a legitimate environment variable? (I've found some references to PYTHON_EGG_CACHE - could be related? But that environment variable isn't set for this user). If it's legit, then I imagine this group has the best chance of recognizing it. Or, given the embedded /bin/sh in the string above, does anyone recognize this as an exploit fingerprint? It wouldn't be the first time we had a cracked account (sigh).

• portable usb harddisk regardless in windows and ubuntu / linux environment

  - by user8184

  I am doing web development mostly in ubuntu. Sometimes i need to go into windows to do other administrative work. Now i am ignorant about file systems. I cannot tell the difference between NTFS and FAT32. My eyes just glaze over the wikipedia articles. All I know is i have been using this 320 Gb portable USB harddisk to save files when I am in ubuntu and when I am in windows. Now i got a situation where sometimes the windows 7 cannot detect the harddisk. I believe it has to do with the file system issue. Or my harddisk is coming apart. To make it easy to backup my files in a portable USB harddisk regardless in ubuntu or windows, please advise me. That means i can go from from linux/ubuntu to portable harddisk read/write files from windows 7 to portable harddisk read/write files the same files. Thank you.

• How to generate the right password format for Apache2 authentication in use with DBD and MySQL 5.1?

  - by Walkman

  I want to authenticate users for a folder from a MySQL 5.1 database with AuthType Basic. The passwords are stored in plain text (they are not really passwords, so doesn't matter). The password format for apache however only allows for SHA1, MD5 on Linux systems as described here. How could I generate the right format with an SQL query ? Seems like apache format is a binary format with a lenght of 20, but the mysql SHA1 function return 40 long. My SQL query is something like this: SELECT CONCAT('{SHA}', BASE64_ENCODE(SHA1(access_key))) FROM user_access_keys INNER JOIN users ON user_access_keys.user_id = users.id WHERE name = %s where base64_encode is a stored function (Mysql 5.1 doesn't have TO_BASE64 yet). This query returns a 61 byte BLOB which is not the same format that apache uses. How could I generate the same format ? You can suggest other method for this too. The point is that I want to authenticate users from a MySQL5.1 database using plain text as password.

• How to find date/time used by Cassandra

  - by JDI Lloyd

  Earlier this morning I noticed that one of the nodes in our Cassandra cluster is writing logs an hour in the future, despite the date/time being correct on the OS. A couple of other nodes I checked via logs appear to be writing logs at the correct time. I now need to go through and check each node in our 80 node cluster and ensure cassandra is running on the correct time, problem being is some of the nodes don't write to the logs very often as they aren't doing much... the question is, is there some form of tool/utility (ie nodetool) that can tell me the time that cassandra is running on? All the systems date/times are correct, ntpdate cron in place has been for a while. Servers are set to Belize timezone to avoid DST changes so its nothing to do with that.

• Windows Explorer slow response when disconnect from the network

  - by ITGuy24

  As a Systems Admin I have seen this issue repeatedly and it drives me crazy. Basically the problem occurs when you open My Documents or My Computer (Windows Explorer) there is a big delay ranging from 5-25 seconds before it actually opens and shows the content. Sometimes the problem continues with each subfolder you open. The problem is most common when disconnected from the network and when you have mapped drives. The most common solution for this problem is to disconnect any mapped drives or printers that are discconected/not reaachable. I have also heard that turning off "Automatically search for network folders and printers" can solve this issue but I have yet to see this work. Does anyone know of any other work arounds for this?

• How to consolidate servers with the not-very-strong infrastructure

  - by Sim

  All, Situation We are in retail industry with about 10 distributors and use Solomon as the standard ERP for all our systems Each distributor has 1 HQ and 5 - 10 branches, each branch has their own server (Windows 2000/XP/2003 + Solomon + another built-in POS system) Everyday, branches has to extract data and send (via email/Skype) to HQ for data consolidation purpose When we first deployed our ERP, the infrastructure (e.g. Internet connection) wasn't reliable enough. That's why we went with the de-centralized model (each branch got their own server) Now, the infrastructure is mature already. And we need to consolidate data more quickly (not from branches -- HQ -- our company but something like HQ -- our company only) Goal We just have Solomon servers in distributor HQ. All the transactions in branches (retrieved from POS) will by synchronized with HQ server directly) There is a backup plan just in case the Internet goes down, or HQ server goes down Question With the above question, could you guys suggests some model for me ? Should we use Terminal services, any other solutions ? Any watchout/suggestions ? Any good article to read 'bout this ? Thanks a lot

• Determine/resolve filepath/alias of a certain command in the Windows command prompt

  - by porg

  How can I find out to which filepath (or alias) a certain command input will point to, in the Windows command prompt? Specifically Windows XP, info on other versions also appreciated! On Unix systems I simply use: $ which commandname /a/commandname Or: $ type -a commandname commandname is aliased to `/b/commandname' commandname is /a/commandname commandname is /b/commandname And I am simply looking for the equivalent in the Windows Shell (specifically Win XP). I came to this general question, from a specific issue: I had installed robocopy.exe (version 026), but the command line "robocopy" always triggers version 010, and I would like to determine where this command points to, in order to correct this mistake.

• What is the difference between /sbin/nologin and /bin/false?

  - by Michael Hampton

  I have often heard it recommended that a user account should be disabled by setting its shell to /bin/false. But, on my existing Linux systems, I see that a great number of existing accounts (all of them service accounts) have a shell of /sbin/nologin instead. I see from the man page that /sbin/nologin prints a message to the user saying the account is disabled, and then exits. Presumably /bin/false would not print anything. I also see that /sbin/nologin is listed in /etc/shells, while /bin/false is not. The man page says that FTP will disable access for users with a shell not listed in /etc/shells and implies that other programs may do the same. Does that mean that somebody could FTP in with an account that has /sbin/nologin as its shell? What is the difference here? Which one of these should I use to disable a user account, and in what circumstances? What other effects does a listing in /etc/shells have?

• Migrate an intermediate CA to a new root

  - by Tim Brigham

  Using the Microsoft CA is there any way to cut over to a new certificate authority from an intermediate authority? Both my systems are Microsoft CAs - I have a 2008 R2 Enterprise CA (intermediate) and an old 2003 CA (root). The 2003 box bit the dust and I don't have good backups. I still have a few months before the CRL expires; instead of having to cut over to a new intermediate authority is there a ready way to simply point this intermediate authority to a new offline CA?

• Desktop totally black, icons gone, taskbar visible, can't browse computer in 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 in Start Search shows "Search failed to initialize". Most programs, including Internet Explorer, Firefox etc work as expected. Anybody ever encountered such abomination?

• how insecure is my short password really?

  - by rika-uehara

  Using systems like TrueCrypt, when I have to define a new password I am often informed that using a short password is insecure and "very easy" to break by brute-force. I always use passwords of 8 characters in length, which are not based on dictionary words, which consists of characters from the set A-Z, a-z, 0-9 I.e. I use password like sDvE98f1 How easy is it to crack such a password by brute-force? I.e. how fast. I know it heavily depends on the hardware but maybe someone could give me an estimate how long it would take to do this on a dual core with 2GHZ or whatever to have a frame of reference for the hardware. To briute-force attack such a password one needs not only to cycle through all combinations but also try to de-crypt with each guessed password which also needs some time. Also, is there some software to brute-force hack truecrypt because I want to try to brute-force crack my own passsword to see how long it takes if it is really that "very easy".

• Suppress log messages about 3ware disk temperature changes on CentOS?

  - by Stefan Lasiewski

  I have a number of CentOS 5 servers which use 3ware RAID controllers. These servers are bugging my team with messages about minor temperature changes, like this: Jun 8 12:32:39 HOST smartd[1231]: Device: /dev/twa0 [3ware_disk_01], SMART Usage Attribute: 194 Temperature_Celsius changed from 119 to 118 Jun 8 12:32:39 HOST smartd[1231]: Device: /dev/twa0 [3ware_disk_03], SMART Usage Attribute: 194 Temperature_Celsius changed from 122 to 121 How can I suppress these messages? According to man smartd.conf : To disable any of the 3 reports, set the corresponding limit to 0. Trailing zero arguments may be omitted. By default, all temperature reports are disabled (´-W 0´). On my systems, smartd is reporting about temperature changes by default. I tried a manual approach. In /etc/smartd.conf, I have the following: /dev/twa0 -d 3ware,1 -a -W 0 /dev/twa0 -d 3ware,3 -a -W 0 But this still does not suppress the messages. Since these messages show up in /var/log/messages, LogWatch is sending unnecessary emails every night.

• In what way does non-"full n-key rollover" hinder fast typists?

  - by Michael Kjörling

  Wikipedia claims (although the latter claim does not cite a source) that: High-end keyboards that provide full n-key rollover typically do so via a PS/2 interface as the USB mode most often used by operating systems has a maximum of only six keys plus modifiers that can be pressed at the same time.[4] This hinders fast typists, ... In what way would the system being able to recognize only six non-modifier keys at once hinder a fast typist? I consider myself a relatively fast typist and I usually press one key, plus modifiers, at once; I can't imagine any real-life situation in which the system only recognizing six non-modifier keys being pressed at once has been a limiting factor in my keyboard usage. (Multi-stroke keyboard shortcuts as used by high-end software like Visual Studio, Emacs and the like are a different matter.) Note that I am not really interested in answers centered around multiplayer computer games; I'm looking for answers that give reasons that would be relevant to typists, somehow supporting the statement made on Wikipedia.

• Test/Dummy SMTP server for Windows

  - by geoaxis

  I would like to install a Test/Dummy SMTP server on a Windows 2008 server (virtual box). I just want to test my web application on the machine it self so I don't need the mails to go out on the internet, but just to be written to disk (so that I can verify that the mail function was indeed called and the correct data was handed over to SMTP) Can you recommend some tool. I guess starting your own SMTP server in python is an option. I am looking for a simple (ready to use) solution, targeted for tests systems. I will need to integrate it to automated tests (Selenium) at a later stage. Thanks

• taskbar-free window manager

  - by 7vies

  I'm looking for a window manager that is not based on the "standard" taskbar (which I find a poor idea and I'm completely tired of). I'm aware of tiling window managers and improvements in last versions of operating systems, but I can't find what I need. I suppose that any window takes the whole screen (or can be tiled), and I imagine switching between windows like that: on a hotkey or mouse hot zone the screen becomes a task switcher where tasks are organized in a somewhat convenient manner. Well, it's a bit like a taskbar with autohide, but I think there could be some more convenient ideas than simply stacking icons and descriptions... It is also supposed to be lightweight enough, for example to run on a netbook. Any suggestions?

• SSH use only my password, Ignore my ssh key, don't prompt me for a passphrase

  - by Stefan Lasiewski

  This is a question regarding the OpenSSH client on Linux, MacOSX and FreeBSD. Normally, I log into systems using my SSH key. Occasionally, I want my SSH client to ignore my SSH key and use a password instead. If I 'ssh hostname', my client prompts me for the Passphrase to my SSH key which is an annoyance. Instead, I want the client to simply ignore my SSH key, so that the server will ask me for my password instead. I tried the following, but I am still prompted for the passphrase to my SSH key. After this, I am prompted for my password. ssh -o PreferredAuthentications=password host.example.org I want to do this on the client side, without any modification of the remote host.

• How do I diagnose a HP Notebook which has hardware issues?

  - by Rob

  My HP DV6t-2300 recently crashed while using FLV Player. It wouldn't start up after this so I had to do a hardware reset (remove power sources, hold down power button ~15 seconds, put back power sources). After this it would turn on, but start up would freeze in Ubuntu, Windows 7, Ubuntu Recovery Mode, and various Linux Live CDs. The only successful way to boot was in Windows 7 Safe Mode. The HP Customer Service was very polite, but they are trying to blame it on a corrupt operating system which is clearly not the case (since I have tried 4 operating systems and none work). I am thinking it might be the GPU since 1) I was watching movies when it crashed and 2) Windows Safe Mode might not use the dedicated GPU. I already ran Memory and HDD tests and there were no detected errors. Any ideas of what's wrong, or suggestions for tests that I should run in safe mode? Should I try reinstalling Windows 7 to convince HP that it's not the OS?
