• HA for Resque & Redis

  - by Chris Go

  Trying to avoid SPOFs for Resque and Redis. Ultimately the client is going to be PHP via (https://github.com/chrisboulton/php-resque). After going through and finding some workable HA for nginx+php-fpm and MySQL (mysql master-master setup as a way to simply master-slave promotion), next up is Resque+Redis. Standard install of Resque uses localhost Redis (at DigitalOcean). I am heavily depending on Amazon Route 53 DNS failover to try to solve this. resque1.domain.com points to localhost redis (redis1.domain.com) = same server resque2.domain.com points to localhost redis (redis2.domain.com) = same server Do resque.domain.com with FAILOVER resque1 as primary and resque2 as secondary. What this means is that most of the time (99%), resque1 should be getting hit with resque2 as just a hot backup. This lets me just have to get 2 servers and makes sure that any hits to resque.domain.com goes somewhere The other way to do this is to break out resque and redis into 4 servers and do it as follows resque1.domain.com - redis.domain.com resque2.domain.com - redis.domain.com redis1.domain.com redis2.domain.com Then setup DNS Failover resque.domain.com - primary: resque1 and secondary: resque2 redis.domain.com - primary: redis1 and secondary: redis2 I'd like to get away for 2 servers if I can but is this 2nd setup much better or negligible? Thanks, Chris

• MySQL binlogs seems incomplete?

  - by warl0ck

  I created a Database, a table and inserted some data, and found this binlog.0000001 in my log folder, but when I do mysqlbinlog binlog.0000001, it only shows stuff below, seems incomplete: (There's only two files in the log dir: binlog.000001 binlog.index) /*!40019 SET @@session.max_insert_delayed_threads=0*/; /*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/; DELIMITER /*!*/; # at 4 #120924 21:12:56 server id 1 end_log_pos 107 Start: binlog v 4, server v 5.5.24-0ubuntu0.12.04.1-log created 120924 21:12:56 at startup # Warning: this binlog is either in use or was not closed properly.

• Drobo FS vs. MacBook Pro: Finder works, Drobo Dashboard doesn't

  - by dash-tom-bang

  Does anyone have any experience with the new Drobo FS, specifically using it from a MacBook Pro? My experience thus far is this: Set up the Drobo Dashboard software (hereinafter called simply 'Dashboard') on my WinXP machine, which is hard-wired to the network to do the data migration from my NAS-that's-being-replaced (a 250G SimpleShare which works well enough but I was always afraid of losing the one disk). The Dashboard seems to work ok, except that the DroboCopy function doesn't work at all. This is the backup solution, which I can configure, and if I launch it (e.g. to back up from the old NAS to the Drobo) it spins the NAS, seeking the drive all over hell and creation, until finally giving up an hour+ later with zero files copied. Selecting only a subset of the data yields the same effect albeit more quickly. On my Mac I installed the Dashboard software too, since most of my fiddling with the device will be from my couch in the living room. Finder connects to the box just fine, fwiw, but Dashboard just sits there, "waiting for connection." This is considerably more bothersome than the above paragraph, but I figured I'd give whatever information I have. Drobo is insisting that I send them this "Debug Log" file that their software generates. Does anyone know what's in it? It's encrypted and they won't tell me, which spooks me just a bit; not like I'm terribly concerned about privacy but I don't want to be sending personal information out to every clown who says they "need" it in order to help me. thanks a ton, -tom!

• Permission denied when running Rails app in VirtualBox Ubuntu guest with files on Windows host

  - by Ola Tuvesson

  I think I'm close to having my dev environment set up exactly the way I want, but one final snag remains. I'm running VirtualBox on a Windows 7 64bit host, with my dev enviroment inside a Ubuntu 12.04 guest. I want to keep the files for my projects on the host filesystem - partly so I can access them when the Ubuntu guest is not running, but also so I can use Tortoise and other Windows based tools (cough Photoshop), and it also eases my backup scheme somewhat. So I've got a folder "Rails" on my NTFS drive, which I've shared (Samba) from the host with a user specifically created for the Ubuntu guest. The mount point has been set up and an entry added to fstab (cifs), using a credentials file and the options iocharset=utf8,mode=0777,dir_mode=07??77 This mounts fine and my Ubuntu user has both read and write permissions to the contents. But when I try to start my Rails app I get permission errors on any files the app needs to write to (e.g. the log file) - why is that? Are there any major conceptual flaws with this approach? Would I be better off using the VBox "shared folders" function?

• How to collect the performance data of a server during an unreachable/down period using Nagios?

  - by gsc-frank

  Some time services and host stop responding due to a poor server performance. I mean, if for some reason (could be lot of concurrency services access, a expensive backup execution on the server or whatever that consume tons of server resources) a server performance is very degraded, that could lead that the server isn't capable to establish any "normal network communication" (without trigger whatever standards timeouts defined for such communication). Knowing host's performance data (cpu, memory, ...) in case of available during that period (host is not down and despite of its performance degradation still allow plugins collect performance data) could be very useful for sysadmin to try to determine what cause the problem, or at least, if the host performance was good and don't interfered at all in the host/service down. This problem could be solved using remote active (NRPE) or remote passive (NSCA) if such remote solutions could store (buffered) perf data to be send to central Nagios server when host performance or network outage allow it. I read the doc of both solutions and can't find any reference to such buffer mechanism neither what happened in case that NSCA can't reach Nagios server. Any idea of how solve this lack of info? so useful for forensic analysis. EDIT: My questions isn about which tools I can use to debug perf problems or gather perf data to analysis, but is about how collect (using Nagios) host perf data even during a network outage for its posterior analysis (kind of forensic analysis). The idea is integrate such data to Nagios graphers like pnp4nagios and NagiosGrapther. I know that I could install tools like Cacti in each of my host, and have a kind of performance data collection redundancy, but I really want avoid that and try to solve all perf analysis requirements with one tools: Nagios

• Exporting Client Data from Groupwise 6.5 to Outlook 2010 without Crashing

  - by Adam Doherty

  My employer has recently moved from Novell GroupWise 6.5 to Exchange 2010. We've imposed mailbox limits on staff but we still need to move their old messages, contacts, calendars, etc. over to Outlook 2010. Our problem however is this, utilizing the Novell MAPI client is slow within Outlook 2010 and upon exporting messages to a PST file (for later re-attachment, and offline backup purposes) crashes the GroupWise server. Connecting to the server in Outlook via IMAP to export messages to PST is faster and apparently more stable but also crashes the server. We'll be keeping our GroupWise server online internally until then end of the year but I have staff with mailboxes approaching 12 gigabytes, which is fine if we're going to move the data to offline storage (DVD set) but if I keep crashing the server every time I try to get the data I'll just be spinning my wheels. In my first attempts, I tried to move mail for a staff member with 3GB of data. The transfer lasted roughly 8 hours before crashing. I'm wondering if there is an open source solution to my problem. Paid solutions exist but we're a not-for-profit organization and have too many staff to justify the costs of per seat licenses just to migrate mail.

• Authenticate users with Zimbra LDAP Server from other CentOS clients

  - by efesaid

  I'am wondering that how can integrate my database,web,backup etc.. centos servers with Zimbra LDAP Server. Does it require more advanced configuration than standart ldap authentication ?

• o2cb thinks ocfs2 cluster is still online, and refuses to shut down

  - by Kendall

  I have a handful of OpenSuSE 11.2 servers that utilize OCFS2 volumes. I've noticed that o2cb can't figure out when the OCFS2 cluster is actually mounted. For example, when I try to shutdown o2cb, after stopping OCSF2, o2cb refuses to shutdown because it thinks OCFS2 is still up! After stopping OCFS2 I try to stop o2cb... hamguy:/dev/disk/by-label # /etc/init.d/o2cb stop Stopping O2CB cluster ocfs2: Failed Unable to stop cluster as heartbeat region still active So I check the status... hamguy:/dev/disk/by-label # /etc/init.d/o2cb status Driver for "configfs": Loaded Filesystem "configfs": Mounted Stack glue driver: Loaded Stack plugin "o2cb": Loaded Driver for "ocfs2_dlmfs": Loaded Filesystem "ocfs2_dlmfs": Mounted Checking O2CB cluster ocfs2: Online Heartbeat dead threshold = 31 Network idle timeout: 30000 Network keepalive delay: 2000 Network reconnect delay: 2000 Checking O2CB heartbeat: Active And double check OCFS2... hamguy:/dev/disk/by-label # /etc/init.d/ocfs2 status Configured OCFS2 mountpoints: /u/conf /u/logs /u/backup /u/client /u/data /u/mdata OCFS2 is clearly down, while o2cb clearly thinks otherwise.

If I try to reboot the machine, it will just sit there forever until your physically power cycle it. That obviously is a bit of a problem. Any insight is appreciated, thank you. Kendall

• nginx+mysql5 loadtesting configuration strangeness

  - by genseric

  i am trying to setup a new server running on debian6 and trying to make it work smooth under load. i ve used a wordpress site as a test object, and tried the configurations on http://blitz.io. when i increase the mysql max_connections from 50 to 200 lots of timeouts start to occur. but on 50 , no timeouts and pretty well response times. nginx configuration is fine , i tuned the config so i dont see errors. so i presume it's related to the other configuration options of my.cnf . i read some about options but still cant find what max_connections problem is all about. btw, the server has 16gb of ram and a fine i7 cpu. here is the current my.cnf [client] port = 3306 socket = /var/run/mysqld/mysqld.sock [mysqld_safe] socket = /var/run/mysqld/mysqld.sock nice = 0 [mysqld] wait_timeout=60 connect_timeout=10 interactive_timeout=120 user = mysql pid-file = /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock port = 3306 basedir = /usr datadir = /var/lib/mysql tmpdir = /tmp language = /usr/share/mysql/english skip-external-locking bind-address = 127.0.0.1 key_buffer = 384M max_allowed_packet = 16M thread_stack = 192K thread_cache_size = 20 myisam-recover = BACKUP max_connections = 50 table_cache = 1024 thread_concurrency = 8 query_cache_limit = 2M query_cache_size = 128M expire_logs_days = 10 max_binlog_size = 100M [mysqldump] quick quote-names max_allowed_packet = 16M [mysql] #no-auto-rehash # faster start of mysql but no tab completition [isamchk] key_buffer = 16M thanks in advance. i asked this question on SO but it's closed as off topic so i believe this is a SF question.

• Cannot login to Windows7 in normal mode but can in safe mode

  - by Guy

  I have a Windows 7 Ultimate computer (Shuttle) that I built myself and in it I put a Solid State Drive (SSD). It's been working well for a number of months but now when I start it there are problems. I have 2 users setup on the computer and when I try and sign in with either user it claims that the password is incorrect. I could understand the odd typo but I've had my wife try it as well and we've got the passwords correct. On top of that it will remain at the login screen for 1 minute and 20 seconds and then spontaneously reboot without shutting down. So I'm trying to work out if this is a hard disk problem or something else. Any ideas? (I have a nightly backup to a WHS so it will be easy to recover but I don't want to do that unless I have to and don't want to waste time putting in a new HD just to discover it's something else.) More info: If I start in Safe Mode I am able to login with the password and all appears as normal as it can in Safe Mode. However, normal boot continues with same problem.

• win8: access denied to external USB disk; update access rights fails

  - by Gerard

  I use to work with 2 laptops (vista and win7), my work being files on an external usb disk. My oldest laptop broke down, so I bought a new one. I had no option other than take win8. 1/ I suspect something changed with access rights, as my external disk suffered some "access denied" problem on win8. I was prompted (by win8) somehow to fix the access rights, which I tried to do, getting to the properties - security. This process was very slow and ended up saying "disk is not ready". Additonnally, the usb somehow was not recognized anymore. 2/ Back to win7, I was warned that my disk needed to be verified, which I did. In this process, some files were lost (most of them i could recover from the folder found00x, but I have some backup anyway). Also, I don't know why, but under win7, all the folder showed with a lock. 3/ Then back again to win8. Same problem : access denied to my disk + no way to change access rights as it gets stuck "disk is not ready". Now I am pretty sure there is some kind of bug or inconsistence in win8 / win7. I did 2/ and 3/ a few times. At some point, I also got an access denied in win7. I could restore access rigths to the disk to "system" (properties - security - EDIT for full control to group "system" ...). But then I still get the same access right pb on win8, and getting stuck in the process to restore full control to "system" -- and "admin" groups. Now, after I tried for more than 3 days, I am losing my patience with that bloody win8 which I did not want to buy but had no choice. I upgraded win8 with the windows updates available. Does not help. Anybody can help me ?

• route propogation using OSPF in a network

  - by liv2hak

  I am using Juniper J-series routers to emulate a small telco and VPN customer.The internal routing will be configured with OSPF,MPLS including a default and backup path,RSVP for distributing labels withing the telco,OSPF for distributing routes from the customer edge (CE) routers to the VRF's in the adjacent PE's and finally iBGP for distributing customer routes between VRF's in different PEs. The topology of the network is shown below. The Addressing scheme for the network is as follows. UOW-TAU ******* ge-0/0/0 192.168.3.1 TAU-PE1 ******* ge-0/0/0 10.0.1.0 ge-0/0/1 10.0.2.0 ge-0/0/2 192.168.3.2 TAU-P1 ****** ge-0/0/0 172.16.1.0 ge-0/0/1 172.16.3.1 ge-0/0/2 10.0.2.2 HAM-P1 ****** ge-0/0/0 172.16.3.2 ge-0/0/1 172.16.2.1 ge-0/0/3 10.0.3.2 ACK-P1 ****** ge-0/0/0 172.16.1.2 ge-0/0/2 172.16.2.2 ge-0/0/3 10.0.1.2 HAM-PE1 ******* ge-0/0/0 10.0.3.1 ge-0/0/2 192.168.4.2 UOW-HAM ******* ge-0/0/0 192.168.4.1 I also set up loopback address for each node. I want to setup OSPF so that path to each internal subnet and router loopback address is propogated to all PE and P nodes.I also want to select a single area for PE and P nodes,and on each node I should add each interface that should be propogated. How do I accomplish this.? With my understanding below is the procedure to achieve this.Is the below explanation correct? I set up OSPF on UOW-TAU ge-0/0/0 interface and ge-0/0/1 interface and UOW-HAM ge-0/0/0 interface and ge-0/0/1 interface. let me call this Area 100. Once I have done this I should be able to reach each node from others using ping and traceroute. Any help is highly appreciated.

• Linux machine can't find its tape drive

  - by Kyle Hodgson

  I have an older HP NetServer LPr with what is apparently a Symbios SCSI card connecting to a Quantum SuperLoader 3 that is DLT based. From time to time, we seem to lose the connection to the autoloader. It's usually due to flaky power, but not totally sure why; sometimes when this happens the Autoloader's LED's are orange and it needs to be power cycled. The annoying workaround currently is to reboot the machine. As it is our production VPN and DNS server in addition to being our backup server, this is less than optimal. In Debian (Sarge) is there not some command one can type to get the card to notice that it has the autoloader connected again? dcr1:/proc# grep -i symbios /proc/pci SCSI storage controller: LSI Logic / Symbios Logic 53c895 (rev 1). dcr1:/proc# uname -a Linux dcr1 2.4.27-3-686 #1 Tue Dec 5 21:03:54 UTC 2006 i686 GNU/Linux dcr1:/proc# mt status mt: /dev/tape: No such device dcr1:/proc# ls -l /dev/tape lrwxrwxrwx 1 root root 8 2007-02-07 16:01 /dev/tape -> /dev/st0 dcr1:/proc# That mt status command will show the actual st0 status when things are working correctly. The No such device message is usually the second clue that we need to reboot - the first clue is usually that the backups didn't run.

• PPTP server connection closes - Too much data?

  - by Sebastian Hoitz

  I set up a PPTP server for my company. However, every time I have another computer connected to this server (i.e. our backup server) and a lot of data gets transferred, the connection to this computer closes. In the syslog on the PPTP server I find this message: Apr 22 12:44:34 komola-chase pptpd[2581]: CTRL: Reaping child PPP[2583] Apr 22 12:44:34 komola-chase pppd[2583]: MPPE disabled Apr 22 12:44:34 komola-chase pppd[2583]: Connection terminated.

• Mirror a RAID0 volume

  - by Ghostrider

  I have two SSD running in RAID0. The capacity and speed are just great. I use Windows Home Server to do incremental daily backups. This is fine and well and I've successfully restored from these backups. However. When one of the disks physically died. I was stuck without a working system until the replacement arrives so that I can restore the array from backup. WHS restoration takes about 5 hours which basically means that I'm losing entire day for the process. Is it possible to set up kind of a recovery volume for the RAID array? Use a single mechanical HDD that would be updated with the exact clone of the RAID array on a daily basis. This way if the array goes offline for some reason, I can just boot from the mechanical HDD, lose some perf but will still be able to work. The machine in question runs Windows 7. Creating RAID01 is not an option because of the high price of the SSD and the fact that it still doesn't protect against failure of RAID controller. Is there any way it can be set up?

• Why would Windows use slower network interface despite route metrics?

  - by tim11g

  On my previous notebook, the Dell/Broadcom wireless adapter had an option to automatically disable wireless when a wired network is connected, so I never dealt with multiple active interfaces. My current system has an Intel wireless adapter, and they apparently haven't figured out how to turn it off when there is a wired connection. Unless I explicitly remember to disable wireless when docked, the connection is active. That shouldn't be a problem (in theory), since the route metric will cause traffic to go over the fastest network (as indicated by the lowest metric in the routing table). Apparently not - I'm running a backup and seeing the throughput at 25Mbps or so (which is consistent with 802.11g) when a perfectly good Gigabit Ethernet interface is also connected. IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 192.168.1.254 192.168.1.104 10 0.0.0.0 0.0.0.0 192.168.1.254 192.168.1.109 25 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 Windows has correctly identified the Ethernet interface (.104) and assigned it the lower (preferred) metric. So the Ethernet interface should be used exclusively, right? Why is the Ethernet connection not being used? What other factors are involved? (This is with Windows 7 if it makes a difference)

• Repairing Damage to VMWare Virtual Disk

  - by Lachlan McDonald

  Evening all, I've got a considerable problem I'm hoping to get some resolution on. I had two VMWare 6.5 virtual machines, one running Ubuntu 9.10 and the other Ubuntu 10.04. I used 9.10 as a testing server, so I could install a LAMP environment to prepare some code. Over the months I took a number of snapshots of this VM just in case something went wrong, and did a full copy of the entire VM a month ago. I created the 10.04 VM when Lucid Lynx launched so I could continue development on a fresh install. To get the files over, I simply added the 9.10 virtual disk into the 10.04 VM, grabbed some of the files I needed, and dismounted it. Unknown to me at the time, the changes to the 9.04 virtual disk meant that I could no longer boot it with the 9.10 VM. I'd always get the "The parent virtual disk has been modified since the child was created." error. I decided this was a good time to backup all the critical files, but now whenever I open the 9.04 disk to get the data it isn't in the same state as it was earlier. My question is; is it possible when I'm mounting the virtual disk that I'm not seeing the most recent snapshot, or in my blundering, have I lost the virtual disk. Cheers

• HTTP Upload Problems

  - by jfoster

  We are running a marketplace on ColdFusion8 and IIS with a widely geographically distributed user base and have been receiving complaints of issues with some HTTP uploads. Most of the complaints are coming from geographically distant locations from our main datacenter on the US east coast. I've attempted to upload the same 70MB file from a US West coast test server to both our main site and a backup running the same code on a different network route and I saw the same issues fairly consistently in both places, so I've ruled out the code, route, and internal network errors. I've also tested uploads using both the native cf upload tag and a third party tool called SaFileUp. I saw the same issues with both upload tools, so I also don't think this is necessarily a ColdFusion problem. I don't have any problems uploading the test file from the East coast to other east coast servers, so I'm beginning to think that the distance between our users and our equipment is a factor. I've also found that smaller files are more likely to succeed than large ones (< 10MB) I tried the test upload with both IE and FF and did notice a difference in the way that the browsers seemed to handle packet errors. IE seemed to have a tough time continuing an upload after dropped / bad packets, whereas FF seemed to have the ability to gracefully resume an upload after experiencing packet problems. Has anyone experienced similar issues? Is there anything we can do on our side to make uploads more forgiving to packet loss or resumable after an error? A different upload tool etc… Do we need upload servers in more than one location to shorten the network routes between clients and servers? Does anyone think that switching uploads to SSL will help (no layer7 packet sniffing may lead to a smoother upload). Thanks.

• How to recover deleted NTFS partitions?

  - by Frank

  Last night I made a terrible mistake. I was reinstalling Windows and I accidentally deleted all the partitions on all my drives. I realized my mistake before I had created any partitions, so nothing has been written to any of the disks. I'm currently at my wits' end about what I'll do if I don't manage to recover the data. I have two 1TB drives and a 2TB. One of the 1TB was the drive I was supposed to be reformatting so nothing to be recovered there. I am currently in a Linux livecd. In this article http://support.microsoft.com/kb/245725 Microsoft advises to recreate the exact same partition but choose not to format it, and then recover the backup boot sector from the end of the ntfs volume. But none of the drives I want to recover are bootable drives. So does that mean I do not need to rewrite the boot sector? As in if I simply recreate a partition of the same size it will see all my data? Or would I be better off using the TestDisk utility? http://www.cgsecurity.org/wiki/TestDisk Please help, I'm desperate!!

• Repairing inconsistent pages in database

  - by Raj

  We have a SQL 2000 DB. The server crashed due to Raid array failure. Now when we run DBCC CHECKDB, we get an error that there are 27 consistency errors in 9 pages. When we run DBCC PAGE on these pages, we get this: Msg 8939, Level 16, State 106, Line 1 Table error: Object ID 1397580017, index ID 2, page (1:8404521). Test (m_freeCnt == freeCnt) failed. Values are 2 and 19. Msg 8939, Level 16, State 108, Line 1 Table error: Object ID 1397580017, index ID 2, page (1:8404521). Test (emptySlotCnt == 0) failed. Values are 1 and 0. Since the indicated index is non-clustered and is created by a unique constarint that includes 2 columns, we tried dropping and recreating the index. This resulted in the following error: CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID 2. Most significant primary key is '3280'. The statement has been terminated. However running Select var_id,result_on from tests group by var_id,result_on having count(*)>1 returns 0 rows. Here is what we are planning to do: Restore a pre-server crash copy of the DB and run DBCC CHECKDB If that returns clean, then restore again with no recovery Apply all subequent TLOG backups Stop production app, take a tail log backup and apply that too Drop prod DB and rename the freshly restored DB to make it prod Start prod app Could someone please punch holes in this approach? Maybe, suggest a different approach? What we need is minimum downtime. SQL 2000 DB Size 94 GB The table that has corrupt pages has 460 Million+ rows of data Thanks for the help. Raj

• Windows Server 2008 32 bit & windows 7 professional SP1

  - by Harry

  I'm testing my new Windows Server 2008 32 bit edition (2 servers) as a server and Windows 7 professional 32 bit as a client. Let say one is a primary domain controller (PDC) and the other is a backup domain controller (BDC) like the old time to ease. Every setup were done in the PDC and just replicate to BDC. Didn't setup anything, just install the server with AD, DNS, DHCP, that's all. Then I use my windows 7 pro 32 bit to join the domain. It worked. After that I tried to change the password of a the user (not administrator) but it always failed said it didn't meet the password complexity setup while in fact there's no setup at all either in account policy, default domain policy or even local policy. Tried to disable the password complexity in the default domain policy instead of didn't set all then test again but still failed. Browse and found suggestion to setup the minimum and maximum password age to 0 but it also failed. Tried to restart the server and the client then change password, still failed with the same error, didn't meet password complexity setup. Tried to see in the rsop.msc but didn't found anything. In fact, if I see the setup in another system with windows server 2003 and windows xp, using rsop.msc I can see there's setup for computer configuration windows settings security settings account policies password policy. I also have a windows 7 pro 32 bit in a windows server 2003 32 bit environment but unable to find the same setting using rsop but this windows 7 works fine. anyone can give suggestion what's the problem and what to do so I can change my windows 7 pro laptop password in a windows server 2008 environment? another thing, is it the right assumption that we can see all the policies setting in windows 7 whether it's in a windows server 2003 or 2008 environment? thanks.

So I should have space now I figure, but whenever I try to restore the ~250mb database now I still get the error message above.. I tried restarting as well but that wasn't helpful. Any idea what the issue is?

• Issues with sustained traffic with PFSense

  - by Farseeker

  Last week we had to replace our PFSense firewall because it had a catastrophic hardware failure. All but one of the NICs were taken out of the old server and put into the new one. The one NIC that was not moved was the LAN NIC as this is on-board. The other NICs are all WAN connections and the must all be present (i.e. I can't disable one just for the sake of testing) After re-installing PFSense and restoring our backup of the configuration, everything came back online just fine, however on the new hardware any download that takes longer than about 10 seconds just times out in the middle. Example 1: Downloading from Microsoft.com goes at about 900k/sec and times out after about 10 seconds (thus, just under 10Mb of content) Example 2: Downloading from cnet.com goes at about 300k/sec and times out after about 10 seconds (thus, about 3Mb of content). By times out, I mean that the download just stops, and you have to pause/resume to get the next part done, repeat and rinse until the download is complete. However it's not consistant, sometimes it's 10 seconds, sometimes it's 4 seconds, and it sometimes you can't even load a heavy HTML page because the page never finishes. I assume this is most likely because PFSense does not like the onboard NIC, as this is the primary difference between the two servers. It's recognised as NFE0, and there's no room in the server for any more NICs and I don't have any dual-port NICs handy to experiment with a different LAN connection. I've never had to troubleshoot this sort of issue before. Can anyone give me some pointers about where to start? Linux is not my forte so please be kind!

• Syncronization between folders MAC OS Lion

  - by Andre Carvalho

  I have an iMac at home and I use a Macbook pro for work. I also have a time capsule at home containing my main folder with my main files. I use it as a NAS besides the Time Machine backup tool. I have several personal files I need to be accessing both at home and at work. My wife, who works at home, uses sometimes the same .XLS files and .DOC files I might have used during my day at work, away from home. My question is: Is there a software, or tool that a I can use to sync my iMac and my MB Pro folders? Remembering that: There might be a chance that my wife and I have changed the same files during the day, so the files would have to be merged so none of the information added by either me or my wife would be lost. The software/tool that would be installed on the MB Pro would need to mount the Time Capsule volume so it could locate the main folder on it. It has to be done automatically when my MB is at home ( with a schedule option ); I have tested some softwares like synctwofolders and Chronosync but none fulfilled all my needs. The first couldn't mount the Time Capsule Volume and didn't have the many schedule options. I really liked Chronosync, but it doesn't merge the files. When it detects a conflict ( for instance: my wife changed a .DOC file on the iMAC and I changed the same file on the MB it asks you to choose which version you want to keep instead of allowing you simply to merge them ).
