  • How to "ignore" username and password prompt in net use

    - by Mattisdada
    I have at the moment a logon.cmd script, that I'm using to map network drives to the users profile. It looks like this: ::Onboarding net use m: /delete net use m: \\BOB\onboarding ::Bookings net use n: /delete net use n: \\BOB\bookings ::Accounts net use j: /delete net use j: \\BOB\accounts It works fine up until it gets up to a folder that the current user cannot access, it then asks for a username and password instead of erroring and continuing. Notes: This very script used to work on another Samba PDC network, but I've moved it over to another server (Still Samba PDC) and now its breaking. Is there anyway for it to ignore the username/password prompt and just continue?

  • Causes of sudden massive filesystem damage? ("root inode is not a directory")

    - by poolie
    I have a laptop running Maverick (very happily until yesterday), with a Patriot Torx SSD; LUKS encryption of the whole partition; one lvm physical volume on top of that; then home and root in ext4 logical volumes on top of that. When I tried to boot it yesterday, it complained that it couldn't mount the root filesystem. Running fsck, basically every inode seems to be wrong. Both home and root filesystems show similar problems. Checking a backup superblock doesn't help. e2fsck 1.41.12 (17-May-2010) lithe_root was not cleanly unmounted, check forced. Resize inode not valid. Recreate? no Pass 1: Checking inodes, blocks, and sizes Root inode is not a directory. Clear? no Root inode has dtime set (probably due to old mke2fs). Fix? no Inode 2 is in use, but has dtime set. Fix? no Inode 2 has a extra size (4730) which is invalid Fix? no Inode 2 has compression flag set on filesystem without compression support. Clear? no Inode 2 has INDEX_FL flag set but is not a directory. Clear HTree index? no HTREE directory inode 2 has an invalid root node. Clear HTree index? no Inode 2, i_size is 9581392125871137995, should be 0. Fix? no Inode 2, i_blocks is 40456527802719, should be 0. Fix? no Reserved inode 3 (<The ACL index inode>) has invalid mode. Clear? no Inode 3 has compression flag set on filesystem without compression support. Clear? no Inode 3 has INDEX_FL flag set but is not a directory. Clear HTree index? no .... Running strings across the filesystems, I can see there are what look like filenames and user data there. I do have sufficiently good backups (touch wood) that it's not worth grovelling around to pull back individual files, though I might save an image of the unencrypted disk before I rebuild, just in case. smartctl doesn't show any errors, neither does the kernel log. Running a write-mode badblocks across the swap lv doesn't find problems either. So the disk may be failing, but not in an obvious way. At this point I'm basically, as they say, fscked? Back to reinstalling, perhaps running badblocks over the disk, then restoring from backup? There doesn't even seem to be enough data to file a meaningful bug... I don't recall that this machine crashed last time I used it. At this point I suspect a bug or memory corruption caused it to write garbage across the disks when it was last running, or some kind of subtle failure mode for the SSD. What do you think would have caused this? Is there anything else you'd try?

  • Debian on Hyper-V

    - by Tobia
    I installed Debian with kernel 2.6.32-5-686 on a Hyper-V virtual machine. I had to add a legacy network card. I follow this tutorial http://www.microsofttranslator.com/bv.aspx?ref=Internal&from=ru&to=en&a=http://blogs.technet.com/b/abeshkov/archive/2011/03/17/hyperv_5f00_debian.aspx to add Hyper-V driver but when I reboot with the new kernel it crash during bootup. Is there any other way to load hyper-v drivers? I really need to change that legacy network card because my debian machine is going to be used as proxy. Thank you.

  • postfix smtp relay script

    - by Peter Sander
    I have a Postfix server and using it with Outlook (POP/SMTP). I have different sender addresses for an account. Now I want to configure a relay for a specific sender address. For example I have postfix for my main domain domain1.com. Now I have a sender address that is domain2.com. For that sender address I want that postfix to relay mail to a second SMTP server. I think that should be possible without problems. But the problem is that I have to create a SSH tunnel to the second server to connect to the SMTP server. But I cant use a persistent SSH connection so I want to know if it is possible that postfix executes some script before relaying the mail to the second SMTP server. I already found some information for executing a script when incomming emails but I only want to establish the SSH tunnel before postfix relays the mail to the second SMTP server.

  • External monitor image not centered in the screen

    - by kemp
    I'm using Xorg 7.5 on a Radeon HD4870 with the FOSS radeonhd server on my HP 6830s. The laptop has a VGA connector and I attach it to a 37" panasonic plasma TV. It works fine except for a little annoyance: when activated, the TV screen is set to the resolution of 1360x768 (which it reports as being the highest it supports) but all the image is shifted by about 100 pixels to the right. I can't see the leftmost part of the page, and I have a black vertical bar to the right. If I change the resolution to 1024x768 there is no shifting, the image fills the entire screen with no parts hidden, but at this resolution the image is stretched. How can I tune the position on the external monitor so that the image is centered in the screen filling it entirely?

  • terminal tools and logs for debugging TCP issues

    - by kellogs
    I have a server which I am testing for functionality (not load, not stress) with tsung. 50 users / second, 100 total users. Judging from tsung (tsung is the testing framework) graphs, there TCP connections (red line) drops to 0 while the commenced user sessions (green line) does not. Server logs show nothing to be gripping onto, so I am speculating some kind of TCP issue. Should this be the case ? Where would I look further on the server, any logs / tools to be looking at ? Only SSH available, no GUI. > root@XMPP:~# cat /etc/lsb-release > DISTRIB_ID=Ubuntu > DISTRIB_RELEASE=11.10 > DISTRIB_CODENAME=oneiric > DISTRIB_DESCRIPTION="Ubuntu 11.10" Thank you

  • Better logging for cronjob output using /usr/bin/logger

    - by Stefan Lasiewski
    I am looking for a better way to log cronjobs. Most cronjobs tend to spam email or the console, get ignored, or create yet another logfile. In this case, I have a Nagios NSCA script which sends data to a central Nagios sever. This send_nsca script also prints a single status line to STDOUT, indicating success or failure. 0 * * * * root /usr/local/nagios/sbin/nsca_check_disk This emails the following message to root@localhost, which is then forwarded to my team of sysadmins. Spam. forwarded nsca_check_disk: 1 data packet(s) sent to host successfully. I'm looking for a log method which: Doesn't spam the messages to email or the console Don't create yet another krufty logfile which requires cleanup months or years later. Capture the log information somewhere, so it can be viewed later if desired. Works on most unixes Fits into an existing log infrastructure. Uses common syslog conventions like 'facility' Some of these are third party scripts, and don't always do logging internally. UPDATE 2010-04-30 In the process of writing this question, I think I have answered myself. So I'll answer myself "Jeopardy-style". Is there any problem with this method? The following will send any Cron output to /usr/bin//logger, which will send to syslog, with a 'tag' of 'nsca_check_disk'. Syslog handles it from there. My systems (CentOS and FreeBSD) already handle log rotation. */5 * * * * root /usr/local/nagios/sbin/nsca_check_disk 2>&1 |/usr/bin/logger -t nsca_check_disk /var/log/messages now has one additional message which says this: Apr 29, 17:40:00 192.168.6.19 nsca_check_disk: 1 data packet(s) sent to host successfully. I like /usr/bin/logger , because it works well with an existing syslog configuration and infrastructure, and is included with most Unix distros. Most *nix distributions already do logrotation, and do it well.

  • Why would one of my servers stop being able to access other servers by FQDN?

    - by Newlyn Erratt
    I have a number of servers on our local network and our debian server has suddenly stopped being able to access the other servers via their FQDN. Initial symptom was inability to login with Active Directory accounts. On further inspection, this machine, porkbelly, was unable to access our other servers (e.g. bacon and albert) via their FQDN. That is, they can ping albert by running ping albert but not by running ping albert.domain.local though when running ping albert it will be expanded to albert.domain.local. The server is still accessible from other servers via both porkbelly and porkbelly.domain.local. Upon examination of hosts information and running hostname its hostname and FQDN are correct. The resolv.conf appears correct. It contains: domain domain.local search domain.local nameserver 192.168.0.xxx (the nameserver) The dns server is also our Windows AD server. I'm not even sure where to go from here or why dns seems to be partially working though I don't have much experience. Where should I go from here? What might be causing this issue where machines are visible via their hostname but not their FQDN?

  • Copy files from sub directories into one directory.

    - by Derek Organ
    Ok I have a bunch of files in this file structure format. /backup/daily/database1/database1-2011-01-01.sql /backup/daily/database1/database1-2011-01-02.sql /backup/daily/database1/database1-2011-01-03.sql /backup/daily/database1/database1-2011-01-04.sql /backup/daily/database1/database1-2011-01-05.sql /backup/daily/database1/database1-2011-01-06.sql /backup/daily/database1/database1-2011-01-07.sql /backup/daily/anotherdb/anotherdb-2011-01-01.sql /backup/daily/anotherdb/anotherdb-2011-01-02.sql /backup/daily/anotherdb/anotherdb-2011-01-03.sql /backup/daily/anotherdb/anotherdb-2011-01-04.sql /backup/daily/anotherdb/anotherdb-2011-01-05.sql /backup/daily/anotherdb/anotherdb-2011-01-06.sql /backup/daily/anotherdb/anotherdb-2011-01-07.sql /backup/daily/stuff/stuff-2011-01-01.sql /backup/daily/stuff/stuff-2011-01-02.sql /backup/daily/stuff/stuff-2011-01-03.sql /backup/daily/stuff/stuff-2011-01-04.sql /backup/daily/stuff/stuff-2011-01-05.sql /backup/daily/stuff/stuff-2011-01-06.sql /backup/daily/stuff/stuff-2011-01-07.sql And there are lots lots more. ultimately I want to import all the 2011-01-07.sql files into my mysql database. This works for one mysql -u root -ppassword < /backup/daily/database1/database1-2011-01-07.sql That will nicely restore that database from this backupfile. I want to run a process where it does this for all databases. So my plan is to first cp all 2011-01-07 sql files into a tmp dir e.g. cp /backup/daily/*/*2011-01-07*.sql /tmp/all The command above unfortunately isn't working I get an error: cp: cannot stat ..... No such file or directory So can you guys help me out with this. For bonus points if you can tell me how to do the next step which is import all databases in one command doing one at a time that would be great too. I really want to do these in two separate steps because I need to delete a few sql files manually from the tmp dir before I run the restore command. So I need: 1) command to copy all 2011-01-07 sql files to a tmp dir 2) command to import all those files in that dir into mysql I know its possible to do in one but for lots of reasons I really would prefer to do it in two steps.

  • Hang while starting several daemons

    - by Adrian Lang
    I’m running a Debian Squeeze AMD64 server. Target runlevel after boot is runlevel 2, which includes rsyslogd, cron, sshd and some other stuff, but not dovecot, postfix, apache2, etc. The system fails to reach runlevel 2 with several symptoms: The system hangs at trying to start rsyslogd Booting into runlevel 1 works, then login from the console works Starting rsyslogd from runlevel 1 via /etc/init.d/rsyslog hangs Starting runlevel 2 with rsyslogd disabled works But then, logging in via console fails: I get the motd, and then nothing Starting sshd from runlevel 1 succeeds But then, I cannot login via ssh. Sometimes password ssh login gives me the motd and then nothing, sometimes not even this. Trying to offer a public key seems to annoy the sshd enough to not talk to me any further. When rebooting from runlevel 1, the server hangs at trying to stop apache2 (which is not running, so this really should be trivial). Trying to stop apache2 when logged in in runleve 1 does hang as well. And that’s just the stuff which fails all the time. RAM has been tested, dmesg shows no problems. I have no clue. Update: (shortened) output from rsyslogd -c4 -d called in runlevel 1 rsyslogd 4.6.4 startup, compatibility mode 4, module path '' caller requested object 'net', not found (iRet -3003) Requested to load module 'lmnet' loading module '/user/lib/rsyslog/lmnet.so' module of type 2 being loaded conf.c requested ref for 'lmnet', refcount 1 rsylog runtime initialized, version 4.6.4, current users 1 syslogd.c requested ref for 'lmnet', refcount now 2 I can kill rsyslogd with Strg+C, then. /var/log shows none of the configured log files, though. Update2: Thanks to @DerfK I still have no clue, but at least I narrowed down the problem. I’m now testing with /etc/init.d/apache2 stop (without an apache2 running, of course) which hangs as well and looks like an even more obvious failure. After some testing I found out that a file with one single line: /usr/sbin/apache2ctl configtest /dev/null 2&1 hangs, while the same line executed in an interactive shell works. I was not able to further reduce this line while, i. e. every single part, the stream redirections and the commando itself is necessary to reproduce the hang. @DerfK also pointed me to strace which gave a shallow hint about what kind of hang we have here: wait4(-1for the init scripts futex(0xsomepointer, FUTEX_WAIT_PRIVATE, 2, NULL for rsyslogd / apache2 binaries called by the init scripts The system was installed as a Debian Lenny by my hoster in autumn 2011, I upgraded it to Squeeze immediately and kept it up to date with Squeeze, which then used to be testing. There were no big changes, though. I guess I never tried to reboot the system before.

  • Want to add a new domain to my postfix, but mails not delivered (mail look back to myself)

    - by user74850
    Hi everybody, My host relay is working but I was aksed to add a new domain (like external.example.com). I have added in main.cf the new fqdn in relay_domains relay_domains = $mydestination, example.com,example2.com, externe.example.com and in transport example.com smtp:[192.168.1.22] example2.com smtp:[192.168.1.22] external.example.com smtp:[192.168.1.22] Mails sent to users with example.com and example2.com domain are well delivered. But for mails to external.example.com i got this message Mar 17 16:47:52 relayhost postfix/smtp[11948]: 754E1876A01: to=<[email protected]>, relay=relayhost2.example.com[80.81.82.83]:25, delay=19555, delays=19525/0.01/30/0, dsn=4.4.6, status=deferred (mail for external.example.com loops back to myself) I read another Q/A about the same issue right here, but it's not helping me. Can you ?

  • Cannot connect to network

    - by dany
    I have a problem: I am on Debian. I configured my nic with a static ip (192.168.1.56). When I try to connect to a network, initially with ifconfig eth2 I get (correctly): eth2 inet addr:192.168.1.56 .... inet6 addr: fe80:221:ff:fe96:4598/64 but after a few seconds the 192.168.1.56 disappears and after some other seconds disappears the inet6 address too. When I press in the nm-applet it requires me the password but in the meantime it try to connect. At uni, the connection is a DHCP one. It works for the first few seconds but after it doesn't. Any possible solution? Here it is the relevant part of the syslog: (static ip configuration) http://pastebin.com/u3BPAsda

  • Need advice on which PCI SATA Controller Card to Purchase

    - by Matt1776
    I have a major issue with the build of a machine I am trying to get up and running. My goal is to create a file server that will service the needs of my software development, personal media storage and streaming/media server needs, as well as provide a strong platform for backing up all this data in a routine, cron-job oriented German efficiency sort of way. The issue is a simple one - all my drives are SATA drives and my motherboard controller only contains 4 ports. Solving the issue has proven to be an unmitigated nightmare. I would like advice on the purchase of the following: 4 Port internal SATA / 2 Port external eSATA PCI SATA Controller Card that has the following features and/or advantages: It must function. If I plug it in and attach drives, I expect my system to still make it to the Operating System login screen. It must function on CentOS, and I mean it must function WELL and with MINIMAL hassle. If hassle is unavoidable, there shall be CLEAR CUT and EASY TO FOLLOW instructions on how to install drivers and other supporting software. I do not need nor want fakeRAID - I will be setting up any RAID configurations from within the operating system. Now, if I am able to find such a mythical device, I would be eternally grateful to whomever would be able to point me in the right direction, a direction which I assume will be paved with yellow bricks. I am prepared to pay a considerable sum of money (as SATA controller cards go) and so paying anywhere between 60 to 120 dollars will not be an issue whatsoever. Does such a magical device exist? The following link shows an "example" of the type of thing I am looking for, however, I have no way of verifying that once I plug this baby in that my system will still continue to function once I've attached the drives, or that once I've made it to the OS, I will be able to install whatever drivers or software programs I need to make it work with relative ease. It doesn't have to be dog-shit simple, but it cannot involve kernels or brain surgery. http://www.amazon.com/gp/product/B00552PLN4/ref=pd_lpo_k2_dp_sr_1?pf_rd_p=486539851&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B003GSGMPU&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1HJG60XTZFJ48Z173HKY So does anyone have a suggestion regarding the subject I am asking about? PCI SATA Controller Cards? It would help if you've had experience with the component before - that is after all why I am asking here - for those who have had experience that I do not have. Bear in mind that this is for a home setup and that I do not have a company credit card. I have a budget with a 'relative' upper limit of about $150.00.

  • (manually configured) kernel update leaves wireless in a mess

    - by Mala
    I recently upgraded my kernel from 2.6.31-gentoo-r6 to 2.6.32-gentoo-r7. In both cases, I configured everything manually. However, since the upgrade, my wireless card appears to be on the fritz. It will connect to networks just fine, and remain connected, but can only access the internet (and other hosts on the network) for about 3 seconds after connecting. Reconnecting to the network appears to fix the problem... for another 3 seconds or so. The problem is "solved" by booting into the older kernel. The relevant lspci entry is 02:00.0 Network controller: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection I'm pretty sure I have the correct drivers enabled in the kernel Device Drivers ---> Network device support ---> Wireless LAN (IEEE 802.11) ---> <*> Intel Wireless Wifi [*] Enable LED support in iwlagn and iwl3945 drivers [*] Enable Spectrum Measurement in iwlagn driver [*] Enable full debugging output in iwlagn and iwl3945 drivers <*> Intel Wireless WiFi Next Gen AGN (iwlagn) [*] Intel Wireless WiFi 4965AGN [*] Intel Wireless WiFi 5000AGN; Intel WiFi Link 1000, 6000, and 6050 Series I tried with the other intel drivers enabled as well (iwl3945) and no difference. Is there something stupid I'm missing? Is there something I have to recompile after upgrading the kernel (a la nvidia)? Thanks Mala

  • Hanging of host network connections when starting KVM guest on bridge

    - by Chris Phillips
    Hi, I've a KVM system upon which I'm running a network bridge directly between all VM's and a bond0 (eth0, eth1) on the host OS. As such, all machines are presented on the same subnet, available outside of the box. The bond is doing mode 1 active / passive, with an arp_ip_target set to the default gateway, which has caused some issues in itself, but I can't see the bond configs mattering here myself. I'm seeing odd things most times when I stop and start a guest on the platform, in that on the host I lose network connectivity (icmp, ssh) for about 30 seconds. I don't lose connectivity on the other already running VM's though... they can always ping the default GW, but the host can't. I say "about 30 seconds" but from some tests it actually seems to be 28 seconds usually (or at least, I lose 28 pings...) and I'm wondering if this somehow relates to the bridge config. I'm not running STP on the bridge at all, and the forwarding delay is set to 1 second, path cost on the bond0 lowered to 10 and port priority of bond0 also lowered to 1. As such I don't think that the bridge should ever be able to think that bond0 is not connected just fine (as continued guest connectivity implies) yet the IP of the host, which is on the bridge device (... could that matter?? ) becomes unreachable. I'm fairly sure it's about the bridged networking, but at the same time as this happens when a VM is started there are clearly loads of other things also happening so maybe I'm way off the mark.

  • Simple mdadm RAID 1 not activating spare

    - by Nick Liu
    I had created two 2TB HDD partitions (/dev/sdb1 and /dev/sdc1) in a RAID 1 array called /dev/md0 using mdadm on Ubuntu 12.04 LTS Precise Pangolin. The command sudo mdadm --detail /dev/md0 used to indicate both drives as active sync. Then, for testing, I failed /dev/sdb1, removed it, then added it again with the command sudo mdadm /dev/md0 --add /dev/sdb1 watch cat /proc/mdstat showed a progress bar of the array rebuilding, but I wouldn't spend hours watching it, so I assumed that the software knew what it was doing. After the progress bar was no longer showing, cat /proc/mdstat displays: md0 : active raid1 sdb1[2](S) sdc1[1] 1953511288 blocks super 1.2 [2/1] [U_] And sudo mdadm --detail /dev/md0 shows: /dev/md0: Version : 1.2 Creation Time : Sun May 27 11:26:05 2012 Raid Level : raid1 Array Size : 1953511288 (1863.01 GiB 2000.40 GB) Used Dev Size : 1953511288 (1863.01 GiB 2000.40 GB) Raid Devices : 2 Total Devices : 2 Persistence : Superblock is persistent Update Time : Mon May 28 11:16:49 2012 State : clean, degraded Active Devices : 1 Working Devices : 2 Failed Devices : 0 Spare Devices : 1 Name : Deltique:0 (local to host Deltique) UUID : 49733c26:dd5f67b5:13741fb7:c568bd04 Events : 32365 Number Major Minor RaidDevice State 1 8 33 0 active sync /dev/sdc1 1 0 0 1 removed 2 8 17 - spare /dev/sdb1 I've been told that mdadm automatically replaces removed drives with spares, but /dev/sdb1 isn't being moved into the expected position, RaidDevice 1. UPDATE (30 May 2012): A badblocks destructive read-write test of the entire /dev/sdb yielded no errors as expected; both HDDs are new. As of the latest edit, I assembled the array with this command: sudo mdadm --assemble --force --no-degraded /dev/md0 /dev/sdb1 /dev/sdc1 The output was: mdadm: /dev/md0 has been started with 1 drive (out of 2) and 1 rebuilding. Rebuilding looks like it's progressing normally: md0 : active raid1 sdc1[1] sdb1[2] 1953511288 blocks super 1.2 [2/1] [U_] [>....................] recovery = 0.6% (13261504/1953511288) finish=2299.7min speed=14060K/sec unused devices: <none> I'm now waiting on this rebuild, but I'm expecting /dev/sdb1 to become a spare just like the five or six times that I've tried rebuilding before. UPDATE (31 May 2012): Yeah, it's still a spare. Ugh! UPDATE (01 June 2012): I'm trying Adrian Kelly's suggested command: sudo mdadm --assemble --update=resync /dev/md0 /dev/sdb1 /dev/sdc1 Waiting on the rebuild now... My questions are: Why isn't the spare drive becoming active sync? How can I make the spare drive become active?

  • Installed over 4G RAM on 32-bit OS? [closed]

    - by kai
    Possible Duplicate: 32-bit Windows Server address > 4GB RAM - How? I know that for 32-bit OS, the addressable memory space for each process is "4G" (maybe just 3G in user space...). If I have a 8G RAM, is it correct that all of the processes can still utilize (shared) these 8G memory but each of them are limited to a maximum 4G? Or the whole system only can see and utilize 4G out of 8G and thus having 8G RAM on a 32-bit OS is the same as having 4G RAM on it?

  • How to log error queries in mysql?

    - by Kaizoku
    I know that there is general_log that logs all queries, but I want to find out which query has an error, and get the error message. I have tried running an error query on purpose, but it logs as a normal query and doesn't report it with error. Any ideas?
