  • Hostname problems in CentOS 5.5

    - by spoon16
    I just set up a CentOS 5.5 machine on my local network and attempted to modify the hostname by editing /etc/sysconfig/network file. When I'm logged in locally the change to the hostname is reflected and seems to be working fine. When I open a SSH session via PuTTY from Windows this is what I see at the prompt: [root@? ~]# cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=mini.local [root@? ~]# sysctl kernel.hostname kernel.hostname = ? [root@? ~]# hostname ? [root@? ~]# hostname -f hostname: Unknown server error A couple of other symptoms that may be helpful in troubleshooting this problem. I can ping the CentOS box from my Windows machine via IP but not hostname. Also, my Netgear router does not display the hostname when I view the "Connected Devices", I do see the mac address and the proper IP listed though. How can I make it so that the hostname is properly propagated throughout my network?

  • Getting packets from one port to another on a Dell PowerConnect 2824 switch

    - by Arvo Bowen
    I have a dell PowerConnect 2824 and I have a cat 5 cable connected from port 1 to port 23. Port 1 is reserved for VLAN 1 (the only VLAN that can manage the switch) and port 18-23 belong to VLAN 112. I currently have the switch setup with ip 10.71.3.5/27 and a test machine plugged into port 22 with IP address 10.71.3.30/27. For some reason I can not ping 10.71.3.5 from my test machine (10.71.3.30). Note: When I try to ping the server plugged into port 21 (IP: 10.71.3.7/27) also VLAN 112, I get responses just fine. Note: When I plug my test machine directly into port 1, I can ping 10.71.3.5 just fine. Quick Recap: Switch IP: 10.71.3.5 Port 1 - dedicated to management - (VLAN1) Port 21 - SERVER (10.71.3.7/27) - (VLAN112) Port 22 - test machine (10.71.3.30/27) - (VLAN112) Port 23 - dedicated to management (to hop over to VLAN 1 from VLAN 112) - (VLAN112)

  • Logrotate Successful, original file goes back to original size

    - by drewrockshard
    Has anyone had any issues with logrotate before that causes a log file to get rotated and then go back to the same size it originally was? Here's my findings: Logrotate Script: /var/log/mylogfile.log { rotate 7 daily compress olddir /log_archives missingok notifempty copytruncate } Verbose Output of Logrotate: copying /var/log/mylogfile.log to /log_archives/mylogfile.log.1 truncating /var/log/mylogfile.log compressing log with: /bin/gzip removing old log /log_archives/mylogfile.log.8.gz Log file after truncate happens [root@server ~]# ls -lh /var/log/mylogfile.log -rw-rw-r-- 1 part1 part1 0 Jan 11 17:32 /var/log/mylogfile.log Literally Seconds Later: [root@server ~]# ls -lh /var/log/mylogfile.log -rw-rw-r-- 1 part1 part1 3.5G Jan 11 17:32 /var/log/mylogfile.log RHEL Version: [root@server ~]# cat /etc/redhat-release Red Hat Enterprise Linux ES release 4 (Nahant Update 4) Logrotate Version: [root@DAA21529WWW370 ~]# rpm -qa | grep logrotate logrotate-3.7.1-10.RHEL4 Few Notes: Service can't be restarted on the fly, so that's why I'm using copytruncate Logs are rotating every night, according to the olddir directory having log files in it from each night.

  • VFS: file-max limit 1231582 reached

    - by Rick Koshi
    I'm running a Linux 2.6.36 kernel, and I'm seeing some random errors. Things like ls: error while loading shared libraries: libpthread.so.0: cannot open shared object file: Error 23 Yes, my system can't consistently run an 'ls' command. :( I note several errors in my dmesg output: # dmesg | tail [2808967.543203] EXT4-fs (sda3): re-mounted. Opts: (null) [2837776.220605] xv[14450] general protection ip:7f20c20c6ac6 sp:7fff3641b368 error:0 in libpng14.so.14.4.0[7f20c20a9000+29000] [4931344.685302] EXT4-fs (md16): re-mounted.

I'm the only one using it, and it's not visible to anyone outside the local network. # lsof | wc 16046 148253 1882901 # ps -ef | wc 574 6104 44260 I saw some documentation saying: file-max & file-nr: The kernel allocates file handles dynamically, but as yet it doesn't free them again. The value in file-max denotes the maximum number of file- handles that the Linux kernel will allocate. When you get lots of error messages about running out of file handles, you might want to increase this limit. Historically, the three values in file-nr denoted the number of allocated file handles, the number of allocated but unused file handles, and the maximum number of file handles. Linux 2.6 always reports 0 as the number of free file handles -- this is not an error, it just means that the number of allocated file handles exactly matches the number of used file handles. Attempts to allocate more file descriptors than file-max are reported with printk, look for "VFS: file-max limit reached". My first reading of this is that the kernel basically has a built-in file descriptor leak, but I find that very hard to believe. It would imply that any system in active use needs to be rebooted every so often to free up the file descriptors. As I said, I can't believe this would be true, since it's normal to me to have Linux systems stay up for months (even years) at a time. On the other hand, I also can't believe that my nearly-idle system is holding over a million files open. Does anyone have any ideas, either for fixes or further diagnosis? I could, of course, just reboot the system, but I don't want this to be a recurring problem every few weeks. As a stopgap measure, I've quit Firefox, which was accounting for almost 2000 lines of lsof output (!) even though I only had one window open, and now I can run 'ls' again, but I doubt that will fix the problem for long. (edit: Oops, spoke too soon. By the time I finished typing out this question, the symptom was/is back) Thanks in advance for any help. And another update: My system was basically unusable, so I decided I had no option but to reboot. But before I did, I carefully quit one process at a time, checking /proc/sys/fs/file-nr after each termination. I found that, predictably, the number of open files gradually went down as I closed things down. Unfortunately, it wasn't a large effect. Yes, I was able to clear up 5000-10000 open files, but there were still over 1.2 million left. I shut down just about everything. All interactive shells, except for the one ssh I left open to finish closing down, httpd, even nfs service. Basically everything in the process table that wasn't a kernel process, and there were still an appalling number of files apparently left open. After the reboot, I found that /proc/sys/fs/file-nr showed about 2000 files open, which is much more reasonable. Starting up 2 Xvnc sessions as usual, along with the dozen or so monitoring windows I like to keep open, brought the total up to about 4000 files. I can see nothing wrong with that, of course, but I've obviously failed to identify the root cause. I'm still looking for ideas, since I definitely expect it to happen again. And another update, the next day: I watched the system carefully, and discovered that /proc/sys/fs/file-nr showed a growth of about 900 open files per hour. I shut down the system's only NFS client for the night, and the growth stopped. Mind you, it didn't free up the resources, but it did at least stop consuming more. Is this a known bug with NFS? I'll be bringing the NFS client back online today, and I'll narrow it down further. If anyone is familiar with this behavior, feel free to jump in with "Yeah, NFS4 has this problem, go back to NFS3" or something like that.

  • Munin "Available entropy" when using address space layout randomization

    - by clawspoon
    Having just configured Munin for statistics logging on my gentoo server (hardened profile), I am noticing that my "Available entropy" is consitently in the 200-300 range. This seems way to low, so I checked it manually using the command $ cat /proc/sys/kernel/random/entropy_avail 3544 Odd. Consistently very low values in Munin and practically filled up when checking manually. After thinking about the problem for a while I came to the conclusion that the problem is probably that I'm using Adress Space Layout Randomization which is using the entropy when running commands/programs. Since Munin runs a whole slew of programs all the entropy is used up, and Munin then measures how much entropy there is, resulting in the low values. Does anyone have any experience with this? How can this be avoided?

  • Running phpmyadmin and suphp

    - by thor
    I have a Debian Lenny web server. It is running apache2 with libapache2-mod-suphp. Unfortunately, suphp makes impossible to use phpmyadmin, as phpmyadmin is installed in /usr/share/phpmyadmin and owned by root, and suphp disables it's enging in this direcory: $ cat /etc/apache2/mods-enabled/suphp.conf <IfModule mod_suphp.c> AddType application/x-httpd-php .php .php3 .php4 .php5 .phtml suPHP_AddHandler application/x-httpd-php <Directory /> suPHP_Engine on </Directory> # By default, disable suPHP for debian packaged web applications as files # are owned by root and cannot be executed by suPHP because of min_uid. <Directory /usr/share> suPHP_Engine off </Directory> </IfModule> Is there a possibility to enable system phpmyadmin (may be through standard libapache2-mod-php5) while using suphp? How?

  • Server not sending a SYN/ACK packet in response to a SYN packet

    - by jeff
    Using iptraf, tcpdump and wireshark I can see a SYN packet coming in but only the ACK FLAG is set in reply packet. I'm running Debian 5 with kernel 2.6.36 I've turned off window_scaling and tcp_timestamps, tcp_tw_recycle and tcp_tw_reuse: cat /etc/sysctl.conf net.ipv4.tcp_tw_recycle = 0 net.ipv4.tcp_tw_reuse = 0 net.ipv4.tcp_window_scaling = 0 net.ipv4.tcp_timestamps = 0 I've attached an image of the wireshark output. http://imgur.com/pECG0.png Output to netstat netstat -natu | grep '72.23.130.104' tcp 0 0 97.107.134.212:18000 72.23.130.104:42905 SYN_RECV I've been doing everything possible to find a solution and have yet to figure out the problem, so any help/suggestions are much appreciated. UPDATE 1: I've set tcp_syncookies = 0 and noticed I am now replying with 1 SYN+ACK for every 50 SYN requests. The host trying to connect is sending a SYN request about once every second. PCAP FILE

  • How to set up Dell OMSA tools on Debian 6 (Squeeze) (PE2950)

    - by javano
    I assume I have set up them up incorrectly or am missing a library or dependency. When I log into the OMSA web interface I can't see anything Also, omreport tells me nothing; root@box:~# omreport storage controller No controllers found I assume these two will use the same source of information so what ever is wrong will fix them both. I set up OMSA as per these instructions. Also I have compiled MegaCLI (as this is a PowerEdge 2950 with a Perc 6/i controller) and I have used that to update the RAID firmware, so that works, but the Dell tools aren't. What have I missed during set up? root@kvm1:~# cat /etc/issue Debian GNU/Linux 6.0 \n \l root@kvm1:~# uname -a Linux kvm1.mivoice.cust.vostron.net 3.4.9 #1 SMP Wed Aug 22 19:08:46 BST 2012 x86_64 GNU/Linux

  • Suppress EXT3-fs warning on mount

    - by STM
    I am familiar with output suppress on Unix machines, ie: cat /file/that/doesnt/exist > /dev/null 2>& However I can't seem to suppress the output of mount when an ext3 filesystem is mounted for the nth time, and it recommends an fsck. As it happens, fscks are run regularly by another machine, so these warning messages are needlessly interrupting the flow of output to my pretty bash script. These are the errors: # mount -t ext3 /dev/sda1 /mnt > /dev/null 2>& kjournald starting. Commit interval 5 seconds EXT3-fs warning: maximal mount count reached, running e2fsck is recommended EXT3 FS 2.4-0.9.19, 19 August 2002 on sd(8,1), internal journal EXT3-fs: mounted filesystem with ordered data mode. Can anyone shed some light on this? I'm clearly blocking both fd's, but somehow output is still getting through. This is GNU Bash v2.05a

  • Caching DNS server (bind9.2) CPU usage is so so so high.

    - by Gk
    Hi, I have a caching-only dns server which get ~3k queries per second. Here is specs: Xeon dual-core 2,8GHz 4GB of RAM Centos 5x (kernel 2.6.18-164.15.1.el5PAE) bind 9.4.2 rndc status: recursive clients: 666/4900/5000 About 300 new queries (not in cache) per second. Bind always uses 100% on one core on single-thread config. After I recompiled it to multi-thread, it uses nearly 200% on two core :( No iowait, only sys and user. I searched around but didn't see any info about how bind use CPU. Why does it become bottleneck? One more thing, here is RAM usage: cat /proc/meminfo MemTotal: 4147876 kB MemFree: 1863972 kB Buffers: 143632 kB Cached: 372792 kB SwapCached: 0 kB Active: 1916804 kB Inactive: 276056 kB I've set max-cache-size to 0 to make sure bind can use as much RAM as it want, but it always stop at ~2GB. Since every second we got not cached queries so theoretically RAM must be exhausted but it wasn't. Do you have any idea? TIA, -Gk

  • Why is the latency on one LVM volume consistently higher?

    - by David Schmitt
    I've got a server with LVM over RAID1. One of the volumes has a consistently higher IO latency (as measured by the diskstats_latency munin plugin) than the other volumes from the same group. As you can see, the dark orange /root volume has consistently high IO latency. Actually ten times the average latency of the physical devices. It also has the highest Min and Max values. My main concern are not the peaks, which occur under high load, but the constant load on (semi-)idle. The server is running Debian Squeeze with the VServer kernel and has four VServer containers and one KVM guest. I'm looking for ways to fix - or at least understand - this situation. Here're some parts of the system configuration: root@kvmhost2:~# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/system--host-root 19G 3.8G 14G 22% / tmpfs 16G 0 16G 0% /lib/init/rw udev 16G 224K 16G 1% /dev tmpfs 16G 0 16G 0% /dev/shm /dev/md0 942M 37M 858M 5% /boot /dev/mapper/system--host-isos 28G 19G 8.1G 70% /srv/isos /dev/mapper/system--host-vs_a 30G 23G 6.0G 79% /var/lib/vservers/a /dev/mapper/system--host-vs_b 5.0G 594M 4.1G 13% /var/lib/vservers/b /dev/mapper/system--host-vs_c 5.0G 555M 4.2G 12% /var/lib/vservers/c /dev/loop0 4.4G 4.4G 0 100% /media/debian-6.0.0-amd64-DVD-1 /dev/loop1 4.4G 4.4G 0 100% /media/debian-6.0.0-i386-DVD-1 /dev/mapper/system--host-vs_d 74G 55G 16G 78% /var/lib/vservers/d root@kvmhost2:~# cat /proc/mounts rootfs / rootfs rw 0 0 none /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0 none /proc proc rw,nosuid,nodev,noexec,relatime 0 0 none /dev devtmpfs rw,relatime,size=16500836k,nr_inodes=4125209,mode=755 0 0 none /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0 /dev/mapper/system--host-root / ext3 rw,relatime,errors=remount-ro,data=ordered 0 0 tmpfs /lib/init/rw tmpfs rw,nosuid,relatime,mode=755 0 0 tmpfs /dev/shm tmpfs rw,nosuid,nodev,relatime 0 0 fusectl /sys/fs/fuse/connections fusectl rw,relatime 0 0 /dev/md0 /boot ext3 rw,sync,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-isos /srv/isos ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_a /var/lib/vservers/a ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_b /var/lib/vservers/b ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_c /var/lib/vservers/c ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/loop0 /media/debian-6.0.0-amd64-DVD-1 iso9660 ro,relatime 0 0 /dev/loop1 /media/debian-6.0.0-i386-DVD-1 iso9660 ro,relatime 0 0 /dev/mapper/system--host-vs_d /var/lib/vservers/d ext3 rw,relatime,errors=continue,data=ordered 0 0 root@kvmhost2:~# cat /proc/mdstat Personalities : [raid1] md1 : active raid1 sda2[0] sdb2[1] 975779968 blocks [2/2] [UU] md0 : active raid1 sda1[0] sdb1[1] 979840 blocks [2/2] [UU] unused devices: <none> root@kvmhost2:~# iostat -x Linux 2.6.32-5-vserver-amd64 (kvmhost2) 06/28/2012 _x86_64_ (8 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 3.09 0.14 2.92 1.51 0.00 92.35 Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 23.25 161.12 7.46 37.90 855.27 1596.62 54.05 0.13 2.80 1.76 8.00 sdb 22.82 161.36 7.36 37.66 850.29 1596.62 54.35 0.54 12.01 1.80 8.09 md0 0.00 0.00 0.00 0.00 0.14 0.02 38.44 0.00 0.00 0.00 0.00 md1 0.00 0.00 53.55 198.16 768.01 1585.25 9.35 0.00 0.00 0.00 0.00 dm-0 0.00 0.00 0.48 20.21 16.70 161.71 8.62 0.26 12.72 0.77 1.60 dm-1 0.00 0.00 3.62 10.03 28.94 80.21 8.00 0.19 13.68 1.59 2.17 dm-2 0.00 0.00 0.00 0.00 0.00 0.00 9.17 0.00 9.64 6.42 0.00 dm-3 0.00 0.00 6.73 0.41 53.87 3.28 8.00 0.02 3.44 0.12 0.09 dm-4 0.00 0.00 17.45 18.18 139.57 145.47 8.00 0.42 11.81 0.76 2.69 dm-5 0.00 0.00 2.50 46.38 120.50 371.07 10.06 0.69 14.20 0.46 2.26 dm-6 0.00 0.00 0.02 0.10 0.67 0.81 12.53 0.01 75.53 18.58 0.22 dm-7 0.00 0.00 0.00 0.00 0.00 0.00 7.99 0.00 11.24 9.45 0.00 dm-8 0.00 0.00 22.69 102.76 407.25 822.09 9.80 0.97 7.71 0.39 4.95 dm-9 0.00 0.00 0.06 0.08 0.50 0.62 8.00 0.07 481.23 11.72 0.16 root@kvmhost2:~# ls -l /dev/mapper/ total 0 crw------- 1 root root 10, 59 May 11 11:19 control lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm1 -> ../dm-4 lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm2 -> ../dm-3 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-isos -> ../dm-2 lrwxrwxrwx 1 root root 7 May 11 11:19 system--host-root -> ../dm-0 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-swap -> ../dm-9 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_d -> ../dm-8 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_b -> ../dm-6 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_c -> ../dm-7 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_a -> ../dm-5 lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm3 -> ../dm-1 root@kvmhost2:~#

  • Watch videos from a remote computer on the LAN on ubuntu

    - by tapan
    I want to watch the videos on a friends computer on the LAN without having to download it. Both of us are running ubuntu. Now one way is to ssh to his computer, cd to the directory where the video is and run the falling command: cat video.avi | ssh me@mycomputer mplayer - This works. However the problem is that I cannot seek inside the video as in can't go forward or backward in it. Is there a method by which I can watch the videos and also seek in them ? I can install any software on his comp and my comp to aid this process. I have root level access on both computers. Any suggestions ?

  • How can I make my monitor run at it's native resolution under Kubuntu 9.10?

    - by Adam Matan
    Hi, I have installed Kubuntu 9.10 afresh on an HP desktop computer with a Samsung SyncMaster 2243 and Intel integrated graphics card. The screen resolution is fixed on 1280x1024 instead of the native 1680x1050, which makes my eyes bleed. $ lspci -k |grep "VGA" -A2 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10) Kernel driver in use: i915 Kernel modules: i915 and my xorg.conf: /etc/X11$ cat xorg.conf Section "Device" Identifier "Configured Video Device" Driver "vesa" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" EndSection Any ideas how to make this driver work?

  • Debian date jumping, causing complete lockup

    - by artfulrobot
    I have a Debian Squeeze VM that has suddenly chosen to jump it's date forwards just over a month, which seems to confuse it no end and cause it to require a hard reset (yikes!). There is nothing unusual in the logs, except that the datestamp suddenly jumps (today back to 2005). It's happened three times, so I don't think it's to do with the leap second issue as the last one of those was in July. When it happened once I spent ages checking stuff but could not find anything, decided to forget it. But three times is becoming an issue on a production server. Edits providing information requested in comments (thanks!): I do not have control over the hypervisor, it is a hired VM. # cat /sys/devices/system/clocksource/clocksource0/current_clocksource kvm-clock # ntpq -p remote refid st t when poll reach delay offset jitter ============================================================================== +grendel.exizten 130.149.17.8 2 u 29 64 77 14.811 1.778 1.744 *panoramix.linoc 193.67.79.202 2 u 32 64 77 19.729 -0.419 1.691 +robert.elnounch 213.251.128.249 2 u 27 64 77 17.762 0.600 1.722 -janetzki.eu 83.169.43.165 3 u 31 64 77 27.214 3.575 1.638

  • Difference between tcp recv buffer and tcp receive window size?

    - by pradeepchhetri
    The command shows the tcp receive buffer size in bytes. $ cat /proc/sys/net/ipv4/tcp_rmem 4096 87380 4001344 where the three values signifies the min, default and max values respectively. Then I tried to find the tcp window size using tcpdump command. $ sudo tcpdump -n -i eth0 'tcp[tcpflags] & (tcp-syn|tcp-ack) == tcp-syn and port 80 and host google.com' tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 16:15:41.465037 IP 172.16.31.141.51614 > 74.125.236.73.80: Flags [S], seq 3661804272, win 14600, options [mss 1460,sackOK,TS val 4452053 ecr 0,nop,wscale 6], length 0 I got the window size to be 14600 which is 10 times the size of MSS. Can anyone please tell me the relationship between the two.

  • OOM-Killer called every now and then..

    - by SpyrosP
    Hello there, i have a dedicated server where i've installed apache2, as well as Rails Passenger. Although i have 2GBs of RAM and most times about 1,5GB is free, there are some random times when i lose ssh and generic connectivity because oom-killer is killing processes. I suppose there is a memory leak but i cannot find out where it comes from. oom-killer kills apache2, mysql, passenger, whatever. Yesterday, i did a "cat syslog | grep -c oom-killer" and got 57 occurences ! It seems that something seriously destroys the memory. Once i reboot, everything comes back to normal. I suspect that it can be related to Passenger, but i'm still trying to figure it out. Can you think of anything else, or do you have anything to suggest that will make the leak identification procedure easier ? (i was even thinking of writing a bash script, to be run with cron for like every 5 minutes).

  • postfix "mail-pipe" alias shellscript creates permissionless files/dirs

    - by Gung Foo
    I am using an alias to a shellscript in postfix... After the script that is called by the shellscript creates a directory it has no permissions at all.. #!/bin/sh umask 002 cat | php /var/www/html/catchmymail rcvemail result is like this: d--------- 2 apache apache 4096 Sep 17 17:25 50 it works for files tho: -rw-rw---- 1 apache apache 5836288 Sep 18 11:21 test Not even setting umask 002 in the shellscript before it hands the mail on changes a thing Setting umask(0002) inside catchmymail has no effect either. Has anyone seen this behaviour before or an idea to save my day?!? This is extremely confusing and actually insane behaviour from what i understand about umask and file permissions.

  • How to test KVM guest CPU maximum allocation limit?

    - by Ace
    Running Ubuntu 13.04 Host and vm Guest. Using virtio for hdd, nic. Max-allocaion CPU cores is 6, minimum is 2. Ive made a vm with virt-manager just to play with, and to test out kvm. Alright, I have a decent understand how the memory balloon driver works, but I still dont know how to test if the guest OS can utilize the max setting for cpu cores. From what i gather, the host will start one thread of qemu for each core allocated per vm. When i run htop inside the guest, it only shows two cores. (also here is the output of cat /proc/cpuinfo: https://gist.github.com/anonymous/93a361545130923537da ) How can I "force" the guest to allocate the other 4 cores so that it can show 6 cores in htop? Is there a way to do this?

  • How to mount remote samba share from local host with multiple groups?

    - by Dragos
    I am using mount.cifs to mount a remote samba share (both client and server are Ubuntu server 8.04) like this: mount.cifs //sambaserver/samba /mountpath -o credentials=/path/.credentials,uid=someuser,gid=1000 $ cat .credentials username=user password=password I mounted a user from local system with username and password with mount.cifs but the problem is that the user is part of multiple groups on the remote system and with mount.cifs I can only specify one gid. Is there a way to specify all the gids that the remote user has? Is there a way to: Mount the remote samba with multiple groups on the local system? Browse the mount from 1) with the terminal since I want to pass some files from samba as arguments to local programs. Other solutions would be: nautilus sftp:// which runs through gvfs; but the newer gnome does not write to disk the ~/.gvfs anymore so I can't browse it in terminal. And the last solution would be NFS but that means that I have to synchronize the uids and gids on the local system with the ones from the server.
