• Problems with connecting Thunderbird client to dovecot installed on Ubuntu

  - by Michael Omer

  I am trying to connect a Thunderbird client to my dovecot server. The dovecot is installed on Ubuntu. I know that my server works (at least partially), since when I send a mail to a user in the server ([email protected]), I see the new file created in /home/feedback/Maildir/new. However, when I try to connect with my Thunderbird to the server, It recognizes the server, but informs me that my user/password is wrong (they are not wrong). The exact message is: Configuration could not be verified - is the username or password wrong? The server configuration it tries to connect to is: incoming - IMAP 143, outgoing - SMTP 587 The dovecot configuration file is located here: dovecot.conf My PAM configuration is: @include common-auth @include common-account @include common-session In the log, I see: May 23 06: 07: 20 misfortune dovecot: imap-login: Disconnected (no auth attempts): ? rip=77.126.236.118, lip=184.106.69.153 Dovecot -n gives me: Log_timestamp: %Y-%m-%d %H: %M: %S Protocols: pop3 pop3s imap imaps Ssl: no Login_dir: /var/run/dovecot/login Login_executable(default): /usr/lib/dovecot/imap-login Login_executable(imap): /usr/lib/dovecot/imap-login Login_executable(pop3): /usr/lib/dovecot/pop3-login Mail_privileged_group: mail Mail_location: maildir: ~/Maildir Mbox_write_locks: fcntl dotlock Mail_executable(default): /usr/lib/dovecot/imap Mail_executable(imap): /usr/lib/dovecot/imap Mail_executable(pop3): /usr/lib/dovecot/pop3 Mail_plugin_dir(default): /usr/lib/dovecot/modules/imap Mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap Mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 Imap_client_workarounds(default): tb-extra-mailbox-sep Imap_client_workarounds(imap): tb-extra-mailbox-sep Imap_client_workarounds(pop3): Auth default: passdb: driver: pam userdb: driver: passwd

• Upstart: cannot run as root

  - by Ronni Egeriis

  I have made this upstart script, which starts a Node.js service. But all of the sudden the service has stopped, and upstart has failed to restart it. Now that I am trying to start it manually, it fails to recognize my service: start: Unknown job: queue The script is properly placed in /etc/init, and should have the correct rights: -rw-r--r-- 1 root root 200 Aug 7 13:30 queue.conf When I check the config file with init-checkconf however, it says that it is not able to run as root: root@production1:~# init-checkconf /etc/init/queue.conf ERROR: cannot run as root What causes this error and how do I solve it?

• Opening an existing process

  - by Grasper

  I am using Eclipse in Linux through a remote connection (xrdp). My internet got disconnected, so I got disconnected from the server while eclipse was running. Now I logged in again, and I do the "top" command I can see that eclipse is running and still under my user name. Is there some way I can bring that process back into my view (I do not want to kill it because I am in the middle of checking in a large swath of code)? It doesnt show up on the bottom panel after I logged in again. Here is the "top" output: /home/mclouti% top top - 08:32:31 up 43 days, 13:06, 29 users, load average: 0.56, 0.79, 0.82 Tasks: 447 total, 1 running, 446 sleeping, 0 stopped, 0 zombie Cpu(s): 6.0%us, 0.7%sy, 0.0%ni, 92.1%id, 1.1%wa, 0.1%hi, 0.1%si, 0.0%st Mem: 3107364k total, 2975852k used, 131512k free, 35756k buffers Swap: 2031608k total, 59860k used, 1971748k free, 817816k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 13415 mclouti 15 0 964m 333m 31m S 21.2 11.0 83:12.96 eclipse 16040 mclouti 15 0 2608 1348 888 R 0.7 0.0 0:00.12 top 31395 mclouti 15 0 29072 20m 8524 S 0.7 0.7 611:08.08 Xvnc 2583 root 20 0 898m 2652 1056 S 0.3 0.1 139:26.82 automount 28990 postgres 15 0 13564 868 304 S 0.3 0.0 26:33.36 postgres 28995 postgres 16 0 13808 1248 300 S 0.3 0.0 6:54.95 postgres 31440 mclouti 15 0 3072 1592 1036 S 0.3 0.1 6:01.54 gam_server 1 root 15 0 2072 524 496 S 0.0 0.0 0:03.00 init 2 root RT -5 0 0 0 S 0.0 0.0 0:04.53 migration/0 3 root 34 19 0 0 0 S 0.0 0.0 0:00.04 ksoftirqd/0 4 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/0 5 root RT -5 0 0 0 S 0.0 0.0 0:01.72 migration/1 6 root 34 19 0 0 0 S 0.0 0.0 0:00.07 ksoftirqd/1 7 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/1 8 root RT -5 0 0 0 S 0.0 0.0 0:04.33 migration/2 9 root 34 19 0 0 0 S 0.0 0.0 0:00.05 ksoftirqd/2

• What should I be doing while I wait for a progress bar?

  - by Malnizzle

  So I am sitting here waiting for a progress bar to run (20 mins or so), and was wondering how best to use my time as a SysAdmin. I debated not posting this question briefly, as this could get flagged as subjective, but I think it's an important question, and a question that can be legitimately answered (per the FAQ) I know this something a lot of sys admins deal with, especially if they are client-based I would venture to guess. There is a lot of material out there about how to multi task, but SysAdmin work is unique in this area as well. I could switch over to another project, but I could get wrapped up in that, and forget about the original project I was working on, and that's hard if you are billing a client for your time, both for tracking your time, as well as being fair to that client. I could check ServerFault, but that isn't directly work related, I could sort my email, so on and so forth. What do you do, or what should I do when I have time waiting for a progress bar? Thanks! (download done, back to work!)

• Cannot Connect To VMWare Guest OS Using Either RDP or VNC

  - by Humanier

  Hi, I have a PC (Windows XP SP3) with VMWare Workstation 7 installed. The VMWare hosts Windows Server 2003 Enterprise Edition R2. RealVNC (4.1.3) is installed on both OS'es. Both of them use Hamachi2. Host OS (WinXP) also runs ZoneAlarm Firewall. Hamachi network is set as trusted. My goal is to allow RDP and VNC connections to be made to the guest OS (Windows Server 2003). Both options work absolutely fine if I connect from the host OS. However I have problems when other computers from our Hamachi network try to connect the guest OS (Win2K3). 1) RDP connections. RDP window opens, shows black content and after 15-20 seconds displays following error: http://lh6.ggpht.com/_yQhsRRimgKU/TArRrtiteQI/AAAAAAAABZA/e96za-y9wzo/rdp_error.JPG 2) RealVCN connections. Users are able to connect but all they see is a black screen inside VNC window. At the same their input (keystrokes or mouse moves/clicks) are visible when looking at the console window of the Win2K3. I really appreciate any ideas on how to resolve mentioned problems. Thank you in advance.

• Suspected brute force attack

  - by HarveySaayman

  Recently I acquired a dedicated server from a local ISP to play around with. As the tags suggest, its a windows server 2008 R2 machine. I've only had it for a few days, and no real traffic is going to it yet. I haven't even deployed a "real" website to it yet. Just a silly page so that I could check IIS, my host headers, DNS records, etc are all configured correctly. While playing around, I noticed a ton of Audit Failure entries in the event viewers security logs. It seems something is trying to access the administrator account, and failing. It smells like a brute force attack to me. My ISP gave me the account details of the administrator account and I used those to RDP into the box, which I've heard is not the securest of situations. I created myself another account and added myself to the administrator group, so im using that account to gain acceess to the machine now. In response to all of this i used http://strongpasswordgenerator.com/ to generate me some 20 character length strong passwords and changed all of my account passwords, even the SQL sa user. I also enabled the auto ban feature of FileZillaServer (my FTP server) My questions: 1) how can i detect this kind of thing better? 2) how can i protect my server from unauthorized access better? PS: I'm a software dev, not a sysadmin so please mind my server security idiot-ness-ness

• How do hdparm's -S and -B options interact?

  - by user697683

  These two options seem confusing. For example: according to the man page -B 254 "does not permit spin-down". However, testing with -B 254 -S 1 the drive does spin down after 5 seconds. -B Query/set Advanced Power Management feature, if the drive supports it. A low value means aggressive power management and a high value means better performance. Possible settings range from values 1 through 127 (which permit spin-down), and values 128 through 254 (which do not permit spin-down). The highest degree of power management is attained with a setting of 1, and the highest I/O performance with a setting of 254. A value of 255 tells hdparm to disable Advanced Power Management altogether on the drive (not all drives support disabling it, but most do). -S Put the drive into idle (low-power) mode, and also set the standby (spindown) timeout for the drive. This timeout value is used by the drive to determine how long to wait (with no disk activity) before turning off the spindle motor to save power. Under such circumstances, the drive may take as long as 30 seconds to respond to a subsequent disk access, though most drives are much quicker. The encoding of the timeout value is somewhat peculiar. A value of zero means "timeouts are disabled": the device will not automatically enter standby mode. Values from 1 to 240 specify multiples of 5 seconds, yielding timeouts from 5 seconds to 20 minutes. Values from 241 to 251 specify from 1 to 11 units of 30 minutes, yielding timeouts from 30 minutes to 5.5 hours. A value of 252 signifies a timeout of 21 minutes. A value of 253 sets a vendor-defined timeout period between 8 and 12 hours, and the value 254 is reserved. 255 is interpreted as 21 minutes plus 15 seconds. Note that some older drives may have very different interpretations of these values.

• Windows 7 restarts while being idle

  - by Ondrej Slinták

  My Windows 7 almost always restarts when I keep it idle for ~20-30mins. It happened randomly before, but lately, if I leave the computer I can be sure it's gonna restart after those 30mins. It never happens when I play games or work tho, just when it's idle. It's a fresh install of Windows 7 64bit. I had also problems while installing it, it always crashed while finalizing the install and I had to reinstall again. Eventually it installed on 3rd or 4th try after I deleted all of my partitions and added them again. I thought it might have been a hardware problem, but temperatures seem to be okay and I have no idea how to track what might have been causing it. Any ideas? I'm running Windows 7 64bit on: Gigabyte EX58-UD4P Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz NVIDIA GeForce GTX 260 6GB of DDR3 1066Mhz RAM WDC WD1001FALS-00J7B0 1TB SATA II I have a very bad feeling it might be something with HDD and its compatibility with Windows 7 as I haven't had those problems for 1 year while I had Vista.

• Using GUI ftp on Win7 and Vista without additional software

  - by Stephen Jones

  Goal: provide a 'no-software' method for 'less technical' users to access password protect ftp location from Win7 and Vista (existing approach for WinXP works). 'No software' method to mean without installing additional software (e.g. FileZilla, WinSCP) - the solution is supplied to external non-technical users. WinXP (works): Using Windows Explorer, WinXP supports non-technical ftp access by pasting: ftp://username:[email protected] into the address bar. The remote ftp site's files / directory structure becomes available and can be copied to / from easily (in the style of local file copy / paste) by a 'less technical' user. Win7 / Vista (doesn't work): Pasting the same URL into the Windows Explorer on Win7 or Vista causes an error: An error occurred opening that folder on the FTP server. Make sure you have permission to access that folder. Details: The connection with the server was reset. Notes: a) The same username/password/server typed from the (DOS) command line achieves access to the server, but this is a more 'technical' solution than desired. I am looking for a WinXP equivalent solution. b) Under 'Control Panel' / 'Internet options' / 'Advanced' tab - the boxes for 'Enable FTP folder view' and 'Use Passive FTP' are ticked (enabled) c) Adding an inbound firewall rule for local port 20 (TCP) was attempted with no difference in results (i.e. failure)

• How to calculate RAM value on performance per dollar spent

  - by Stucko

  Hi, I'm trying to make decisions on buying a new PC. I have most specifications (processor/graphic card/hard disk) pin-downed except for RAM. I am wondering what is the best RAM configuration for the amount of money I'm spending. As the question of best is subjective, I'd like to know how would I calculate the value of RAM sticks sold. 1.(sample)The value of amount of memory: 1) CORSAIR PC1333 D3 2GB = costs $80 2) CORSAIR PC1333 D3 4GB = costs $190 would it be better to buy 2 of item 1) instead of 1 of item 2) ?? Although I would normally choose to have 1 of 2) as the difference is only (190-(80*2)) = 30 as I would save 1 DIMM slot, What I need is the value per amount: 1) 80/ 2 = $40 per 1GB 2) 190/ 4 = $47.5 per 1GB 2. The value of frequency: 1) CORSAIR PC1333 4GB = costs 190 2) CORSAIR PC1600C7 4GB = costs 325 Im not even sure of the denominator ... $ per 1 ghz speed? 3. The value of latency: 1) CORSAIR CMP1600C8 8-8-8-24 2GBx3 (triple channel) = costs 589 2) CORSAIR CMP1600C7D 7-7-7-20 2GBx3 (triple channel) = costs 880 Im not even sure of the denominator ... $ per 1 ghz speed? Just for your information i'd like to get the best out of the money im going to spend to put on a 6 DIMM slot i7core motherboard.

• How to choose which network connection provides the default gateway in Windows XP

  - by Cathy

  I have a laptop with an integrated NIC and a WiFi connection. Both the wired and wireless networks I am using can access the Internet. Win XP is routing all traffic through the wireless network. I want to force it to route everything through the wired network when it is available (i.e. when I am sitting at my desk with the laptop docked) and through the wireless when that is the only option (i.e. when I have undocked my laptop and carried it to a conference room, or if I am out of the office working on a different WiFi network). The wireless connection cannot be established until after I am logged into Windows, so it's always the second network to become available to the OS. I have manually overridden the metric values in the TCP/IP configurations so that the NIC has metric 10 and the WiFi has metric 20. However, Windows is still picking the WiFi adapter's address as the Default Gateway, so this isn't helping. If I manually disable and re-enable the WiFi adapter, then it will switch the default gateway to the wired network and stay that way until I shutdown Windows. How can I tell Windows XP not to replace the default gateway when the WiFi connection is first enabled?

• Improving browser performance while using lots of tabs?

  - by Andrew

  My browsing habits cause me to open lots of windows and tabs, either related to different projects I'm working on or things I may want to read later. I use OSX and use about 5 spaces with multiple windows in each space. The problem is eventually I'll have around 200 or more tabs open (spread over 15-20 windows) that I don't want to close. Needless to say, my computer's performance starts to degrade. As I write this on my mobile, Safari on my laptop is locking up the computer. I used to use Chrome but found better performance with Safari. What I'd like to know, is there a graph of browser performance based on tab usage? I don't need a browser that keeps all tabs active. It would be great if the browser could increase performance by "putting tabs to sleep". Or if there was some sort of tool for saving a "workspace" of tabs that you could reactivate the next time you are working on that project. What sort of solution can you recommend to solve this problem?

• How to install Red Hat Enterprise Linux on Apple Macbook Pro MacBookPro4,1

  - by Todd V. Rovito

  I have a one year old Mac Book Pro that I am trying to get RHEL 5.4 installed on via bootcamp. No matter what I do I can't get the installer to boot. I have tried multiple DVD's and even verified the install works on a new Mac Book Pro. Most of the time the installer simply locks up. I usually use Linux text with all-generic-ide on the boot line. I removed the ide parameter and I just used linux text. The results I get are that a bunch of kernel messages appear then the background turns blue and a thin text box pops up saying its loading ata..... something it disappears too fast for me to read. Then the machine freezes. I pressed the alt function keys to see if I could look at the system log, here is what it says: Alt-f3 says "trying to mount CD device hda" Alt-f4 says status error: hda: lastFailedSense Hda: Failed opcode was: unknown Hda: Lost interrupt Hda: Drive not ready for command Ide-cd: command 0x3 timed out Above this junk it looks like it found the partition because it knew it was 20 GB and listed as /dev/sda3. I think it has something to do with the CD drive, is that possible? Thanks again for the support. PS I posted in the apple support forums ( Apple.com Support Discussions Boot Camp Installation and Storage) and didn't get an answer.

• Managing multiple IMAP accounts in Thunderbird

  - by baritoneuk

  I've been using Thunderbird for years without issues with 20+ pop3 accounts. I'm moving over to imap which will enable me to keep copies of the emails locally and on the server whilst keeping everthing synchronised. However I'm looking for the best way to manage multiple imap accounts on Thunderbird. Currently I have a filter that copies all the emails into a central inbox and into seperate local folders. The reason for this is I go through my inbox daily and delete all emails that don't require any action. I move any emails that require action to my "action" imap account folder. This way I can syncronise all the emails that require action across multiple computers (and mobile devices). This technique is my implemantion of the GTD or Getting things Done philosophy. I also copy over each email into seperate local folders. The reason I do this is just in case any emails on the imap accounts get deleted, or something drastic happens on the server which means I lose all the emails. My business partner has access to some of these emails and still uses pop3 (with "leave copy on server" checked), but I know sometimes Thunderbird can still delete emails off the server sometimes. The problem with the above is that thunderbird gives me the dreaded error dialogue saying that the emails cannot be filtered due to another process. I find the folder list in Thunderbird hard to manage. Here is a screenshot of part of my folder list- as you can see it's a bit of a complicated list and not easy to manage: What would be the best way of me managing multiple imap accounts whilst allowing me to have copies put in a central folder and emails in local folders? It would be useful if people think this is necessary, as perhaps there is a betterway? How do people manage multiple imap accounts in a way that allows them to keep on top of actionable emails? I'd be interested in how others manage this. I've never used the Thunderbird-based client "Postbox", does this handle multiple imaps better?

• sharing a folder between linux and windows over the internet

  - by valya

  Hello Currently my job is to make websites with Django. I use many things like virtualenv, PIL, etc. The problem is, I can't stand Linux on my desktop. I like it on servers, It's greate to use it over the SSH. But for desktop? No way. But for the development Linux is quite essential. Of course almost everything is ported to Windows, but it's not as simple to use as in Linux. For example, Windows shell is awful in comparison with Linux. So I've tried Cygwin, but it's too damn slow. Every time django dev server reloads, it tooks almost 20-30 seconds. In comparison, then using "native" python on Windows or Linux, it reloads instantly. Even worse, Cygwin makes all my system very slow. I've been thinking about it and have thought up a way to go. I can share a folder with my application with some Linux box. The devserver and everything will run on that box, while I'll be happy editing files and running the browser on my Windows 7. SSH shell is much quickier and handy than Cygwin. Currently there are no Linux boxes in my home network (except for my android phone :) but I have several VDS boxes with Debian. So, how do I share a Windows folder with VDS box? I can't rely on my desktop IP but I can rely on the VDS's one. I need sharing to be as quick as possible (well, 2-3 seconds ping is OK) and "native" for both systems, so I could use a folder like a normal folder in both Windows and Linux.

• iPhone Lag Terrible - SLOW - What's going on with the iPhone OS?

  - by Sam Schutte

  I've had my iPhone 3G for about a year now, and it seems like at least once a month, it gets bogged down and gets slower and slower - horrible lag when typing, going back to the home screen or opening an app can take 20 seconds. Has anyone else run into this and found "the" solution. What you always read on other boards is to reboot the handset (hold down home and the power button), but that doesn't improve anything for me. I've reinstalled the OS like 5 times now, and I'm getting pretty sick of doing it so often. And I don't buy that it's a hardware issue really, since it works fine for weeks after a fresh install. Anyone have a solution or an idea of what specific actions cause this kind of evident data corruption (OS corruption?) and slowness? Note - I'm looking for specific things here. That is, has anyone done the research to see exactly what on the phone operating system is getting messed up that causes this lag (which is discussed all over the internet, with no working solutions). I don't own a mac, so I can't delve into the guts of the iPhone very well to see what's up with it... Some additional info: Reboots (hold down power/home) and "Sleeps" (slide off) do nothing. Only fresh re-installs help I only have about 15 apps installed - sometimes you see the answer to uninstall apps if you have too many, I'd hope that 15 isn't too many, and even when I've had none installed, it still gets hung up after a period of time. This phone is not jailbroken, and it is running the 3.0.1 release.

• Can Vista Windows Explorer be repaired/fixed?

  - by gurun8

  I'm running Windows Vista Home Premium on a Sony Vaio laptop. I think somehow my Windows Explorer has become corrupted. I don't recall any certain inciting incident like installing an unreputable 3rd party app or hardware failure but just recently my system won't wake after it's been left idle longer that 20 minutes and goes to sleep. I've also had problems launch certain apps, like Adobe InDesign CS3, that just basically freeze the system but leave mouse movements functioning for a short time before freezing the entire system which requires a hard reboot to resolve the freeze. The system seems to run normally when used but I fear there's a looming possibility that this is a house of cards and will all come crashing down soon. My question is this, can Windows Explorer be repaired/fixed? Before reformatting the system and starting over, which is most likely what I'm going to be forced to do, I'd like explore (no pun intended) my options in fixing the problem with a patch or reinstall or something of that nature. Reformatting my system will eat up a day or two of my time and I just don't have the time to spare right now.

• Copying compressed files from Server 2008 R2 network share to XP client via VPN fails

  - by Dejan Janjuševic

  At the first sight the question looks similar to this one. I have experienced an odd behavior while trying to copy a certain file from Windows Server 2008 R2 network share to Windows XP Professional client via VPN. The VPN was set up using RRAS on the server machine. I will try to provide as much informations as possible in order to make the issue more clear. When trying to copy the compressed file sized ~2.5 MB (via Explorer or CMD, doesn't matter), the process stalls after some 20%, producing an error message after few seconds: Cannot copy filename: The specified network name is no longer available. If i start the command ping -t 192.168.2.1 (where the IP address specified belongs to the server) side by side with the copy command, I can clearly see that the ping command times out for few seconds as the copy process stalls. When this happens all network activities are frozen. After a few seconds, the network recovers, ping continues to run normally, however the copy process stands still before it displays the above error message. Copying other files (I tried 4-5 files), of which some are larger and some are smaller, succeeds. Seems to me that I can copy all uncompressed files. As soon as I try to copy an archive, the process freezes. Even a 707 KB large archive can't be copied. I can only reproduce this behavior on 2 machines, both Windows XP Professional, one is w/ SP2 and the other w/ SP3. Other XP clients don't have this problem, neither do Windows 7 clients. If I connect to the server using Remote Desktop Connection without using VPN from either of these 2 machines (using the same user account), I can copy anything I want normally, even these "problematic" files. Does anyone have any clue about what could possibly be going on?

• tap interfaces always disabled in linux bridge

  I have a physical interface eth0, and I want to create two virtual interfaces and bridge them with eth0. For this purpose I do: #Create the virtual interfaces tunctl -t tap0 tunctl -t tap1 ifconfig tap0 up ifconfig tap1 up #Create the bridge brctl addbr br0 brctl stp br0 off brctl addif br0 eth0 brctl addif br0 tap0 brctl addif br0 tap1 #Turning up the bridge ifconfig br0 up However my problem if that the tap interfaces always appear disabled in the bridge, and no traffic flows to them. $brctl show br0 bridge name bridge id STP enabled interfaces br0 8000.080027cabeba no eth2 tap0 tap1 $brctl showstp br0 br0 bridge id 8000.080027cabeba designated root 8000.080027cabeba root port 0 path cost 0 max age 20.00 bridge max age 20.00 hello time 2.00 bridge hello time 2.00 forward delay 15.00 bridge forward delay 15.00 ageing time 300.01 hello timer 0.00 tcn timer 0.00 topology change timer 0.00 gc timer 298.42 flags eth2 (1) port id 8001 state forwarding designated root 8000.080027cabeba path cost 4 designated bridge 8000.080027cabeba message age timer 0.00 designated port 8001 forward delay timer 12.97 designated cost 0 hold timer 1.24 flags tap0 (2) port id 8002 state disabled designated root 8000.080027cabeba path cost 100 designated bridge 8000.080027cabeba message age timer 0.00 designated port 8002 forward delay timer 0.00 designated cost 0 hold timer 0.00 flags tap1 (3) port id 8003 state disabled designated root 8000.080027cabeba path cost 100 designated bridge 8000.080027cabeba message age timer 0.00 designated port 8003 forward delay timer 0.00 designated cost 0 hold timer 0.00 flags Is there any way to set the tap interfaces in forwarding state? I do not understand why they are not because STP is disabled. Cheers Daniel

• Cannot access server shares over VPN

  - by DuncanDavies

  I've set up a single hosted server to use as a development environment for a web-based application. The web app is served up fine on port 80, however I'm struggling to get my VPN to behave how I'd expect so the developers don't have the access they require. The VPN connects fine and I can access the back-end database (SQL Server) which resides on the server with the client tools from the laptops. However they cannot access any shared folders. The server's local IP address is 10.x.x.x, and I've assigned a static IP address pool to RRAS (of 192.168.100.1 - 20). The clients pick up a valid IP Address (i.e. 192.168.100.9) when they connect. There is no name resolution setup, DNS or WINS. When connected via VPN the clients can ping the server (192.168.100.1) by IP Address, but cannot map a drive to a shared folder (net use * \\192.168.100.1\xxxxx) - I get 'System error 53 has occurred. The network path was not found.' I don't understand why I can ping by the ip, but not map by it. Some details: Server OS is Windows 2008 (Datacenter) VPN is SSTP using RRAS Clients are all Windows 7 I've tried temporarily disabling the firewalls So, why can we not access the file system when everything else (ping, RDP, SQL Server clients tools) works? Thanks for your help Duncan

• rsnapshot schedule overlapping, help with backup schedule

  - by Znarkus

  Hello, I have to following configuration. rsnapshot.conf interval halfhourly 4 interval hourly 6 interval twohourly 12 interval daily 7 interval weekly 4 crontab 0,30 * * * * /usr/bin/rsnapshot halfhourly >> /var/log/rsnapshot.halfhourly.log 2>&1 5 * * * * /usr/bin/rsnapshot hourly >> /var/log/rsnapshot.hourly.log 2>&1 10 */2 * * * /usr/bin/rsnapshot twohourly >> /var/log/rsnapshot.twohourly.log 2>&1 15 3 * * * /usr/bin/rsnapshot daily >> /var/log/rsnapshot.daily.log 2>&1 20 6 * * MON /usr/bin/rsnapshot weekly >> /var/log/rsnapshot.weekly.log 2>&1 Only halfhourly is running correctly now. hourly spits out this error: rsnapshot encountered an error! The program was invoked with these options: /usr/bin/rsnapshot hourly ---------------------------------------------------------------------------- ERROR: Lockfile /var/run/rsnapshot.pid exists and so does its process, can not continue To me it seems like my 5 min space between halfhourly and hourly is too small. Is this configuration crazy? I like having backups every thirty minutes, that will probably save my ass some day. Please help me make a decent backup schedule, that doesn't clog up the system, but creates frequent enough backups. Thank you.

• Event Log "Wake Source" when system wakes from sleep

  - by Doltknuckle

  So I've been troubleshooting sleep timers for our systems and have run across an interesting issue. I need a way to report how long a system was awake after a number of different inputs. Now, I've discovered that the System Log tracks wake and sleep events and even tells you the times that everything happens at. The thing is doesn't tell you is what triggered the wake event. It does give you a numerical code however. Here are some examples of what I am finding. Index : 2901 EntryType : Information InstanceId : 1 Message : The system has resumed from sleep. Sleep Time: 2010-10-01T23:20:06.097488100Z Wake Time: 2010-10-03T17:41:12.796400500Z Wake Source: 0 Category : (0) CategoryNumber : 0 Source : Microsoft-Windows-Power-Troubleshooter -- Index : 2841 EntryType : Information InstanceId : 1 Message : The system has resumed from sleep. Sleep Time: 2010-10-01T19:19:37.239789600Z Wake Time: 2010-10-01T21:28:48.921200800Z Wake Source: 4HID Keyboard Device Category : (0) CategoryNumber : 0 Source : Microsoft-Windows-Power-Troubleshooter So here's my question: Does anyone know what the different numerical codes for the "Wake Source" mean? I think "0" is a magic packet and "4" is a USB device. Does anyone have any idea if there is any documentation out there on this for Windows 7? Thanks in advance

• How to block/avoid a particular IP when connecting to websites?

  - by Mark

  I'm having trouble connecting to a particular website. I can view it through a proxy, but not from home. So I ran a traceroute: Tracing route to fvringette.com [76.74.225.90] over a maximum of 30 hops: 1 <1 ms <1 ms <1 ms <snip> 2 * * * Request timed out. 3 9 ms 7 ms 27 ms rd2bb-ge2-0-0-22.vc.shawcable.net [64.59.146.226] 4 8 ms 7 ms 7 ms rc2bb-tge0-9-2-0.vc.shawcable.net [66.163.69.41] 5 10 ms 9 ms 9 ms rc2wh-tge0-0-1-0.vc.shawcable.net [66.163.69.65] 6 27 ms 23 ms 22 ms ge-gi0-2.pix.van.peer1.net [206.223.127.1] 7 18 ms 18 ms 20 ms 10ge.xe-0-2-0.van-spenc-dis-1.peer1.net [216.187.89.206] 8 9 ms 11 ms 10 ms 64.69.91.245 9 * * * Request timed out. 10 * * * Request timed out. ... Looks like this "64.69.91.245" is somehow blocking me. Can I tell my computer to avoid/bypass that IP when trying to connect?

• Wireless to Wireless Transfer Slow on a Linksys WRT54GL

  - by Kyle Brandt

  The Situation: When I try to transfer a file from one computer to another that are both connected via wireless on a WRT54GL (in a office) with dd-wrt firmware I often get bad speeds. In generally they average around 100 kilobytes a second. Either computer can download via wireless from the Internet at at about 2 megabytes a second. The speed is slow with the transfer of one large file. There are about 20 other wireless networks that the computers can see, so there is a lot of noise, but I don't have the equipment to really monitor the frequencies well. But that still seems pretty slow. I thought maybe it was the transmit on each card, but even when they are 5 feet away with a line of sight I still get these speeds. According to Linux both cards are operating at 54g. My Questions: Is this normal for this sort of consumer level wireless equipment? Anything I can do to improve it? why is wireless to wireless transfer slow when everything else isn't? Whats steps might I take to figure out what is happening? For example, are lots of packets not making to the access point requiring retransmissions? Above all, I want to find out what the problem actually is. This may seem odd, but at this point I am more interested in understanding what the problem is than fixing it. What I have tried: I have tried messing with lots of settings. Different channels, xmit power, G-Only, none of which has made anything any better. I've also tried upgrading to newer dd-wrt firmware version and doing a reset to wipe out the settings.
