• Caching/preloading files on Linux into RAM

  - by Andrioid

  I have a rather old server that has 4GB of RAM and it is pretty much serving the same files all day, but it is doing so from the hard drive while 3GBs of RAM are "free". Anyone who has ever tried running a ram-drive can witness that It's awesome in terms of speed. The memory usage of this system is usually never higher than 1GB/4GB so I want to know if there is a way to use that extra memory for something good. Is it possible to tell the filesystem to always serve certain files out of RAM? Are there any other methods I can use to improve file reading capabilities by use of RAM? More specifically, I am not looking for a 'hack' here. I want file system calls to serve the files from RAM without needing to create a ram-drive and copy the files there manually. Or at least a script that does this for me. Possible applications here are: Web servers with static files that get read alot Application servers with large libraries Desktop computers with too much RAM Any ideas? Edit: Found this very informative: The Linux Page Cache and pdflush As Zan pointed out, the memory isn't actually free. What I mean is that it's not being used by applications and I want to control what should be cached in memory.

• Linux monitor logs and email alerts?

  - by Physikal

  I have a server with a faulty power button that likes to reboot itself. Usually there are warning signs, like the acpid log file in /var/log starts spamming garbage for about 10hrs or so. Is there an easy way I can have something monitor the acpid log and email me when it has new activity? I wouldn't consider myself extremely advanced so any "guides" you may have for accomplishing something like this would be very helpful and much appreciated. Thank you!

• Diagnosing Hardware Problem in Linux Server that's Kernel Panicking

  - by Jeremy Privett

  We have a server that has been occasionally kernel panicking for a while now that we believe has a hardware problem. How would you go about troubleshooting hardware that you don't have physical access to? Are there any tools that I can use within the OS itself to diagnose different pieces of the system to try to figure out what's causing all of this panicking?

• Linux: Send mail to external mail box from a server with that user's hostname

  - by dtbarne

  I've got sendmail running on a linux box. Let's say the hostname of the box is bar.com. If I run the following command, I don't receive the email (which is hosted with a third party), presumably due to the hostname pointing to the local machine. echo "Test Body" | mail -s "Test Subject" [email protected] Is there any way to get this to work so that I can receive emails at my third party email address even though it has the same hostname? Do I have to change the hostname of this server (not preferred)? It may be worth noting that I created a user "foo" on my machine and noticed that the mailbox for that account is empty. I noticed these log entries, which may or may not be relevant: Jun 28 01:09:48 bar sendmail[14338]: p5S59min014338: from=apache, size=80, class=0, nrcpts=1, msgid=<[email protected]>, relay=apache@localhost Jun 28 01:09:48 bar sendmail[14339]: p5S59mIA014339: from=<[email protected]>, size=293, class=0, nrcpts=1, msgid=<[email protected]>, proto=ESMTP, daemon=MTA, relay=localhost.localdomain [127.0.$ Jun 28 01:09:48 bar sendmail[14338]: p5S59min014338: [email protected], ctladdr=apache (48/48), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30080, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (p5S59mIA$ Jun 28 01:09:48 bar sendmail[14340]: p5S59mIA014339: to=<[email protected]>, ctladdr=<[email protected]> (48/48), delay=00:00:00, xdelay=00:00:00, mailer=local, pri=30495, dsn=2.0.0, stat=Sent

• High data on recv-q buffer and thread lock on java.io.BufferedInputStream in linux

  - by Sagar Patel

  We have a java application running on linux (ubuntu server). We have been facing high recv-q problem since quite some time. Application gets hang and does not read data from socket every few hours. In thread dump, we have found below stack trace.

• TCP dies on a Linux laptop

  - by Roman Cheplyaka

  Once in several days I have the following problem. My laptop (Debian GNU/Linux testing) suddenly becomes unable to work with TCP connections to the internet. The following things continue to work fine: UDP (DNS), ICMP (ping) — I get instant response TCP connections to other machines in the local network (e.g. I can ssh to a neighbour laptop) everything is ok for other machines in my LAN But when I try TCP connections from my laptop, they time out (no response to SYN packets). Here's a typical curl output: % curl -v google.com * About to connect() to google.com port 80 (#0) * Trying 173.194.39.105... * Connection timed out * Trying 173.194.39.110... * Connection timed out * Trying 173.194.39.97... * Connection timed out * Trying 173.194.39.102... * Timeout * Trying 173.194.39.98... * Timeout * Trying 173.194.39.96... * Timeout * Trying 173.194.39.103... * Timeout * Trying 173.194.39.99... * Timeout * Trying 173.194.39.101... * Timeout * Trying 173.194.39.104... * Timeout * Trying 173.194.39.100... * Timeout * Trying 2a00:1450:400d:803::1009... * Failed to connect to 2a00:1450:400d:803::1009: Network is unreachable * Success * couldn't connect to host * Closing connection #0 curl: (7) Failed to connect to 2a00:1450:400d:803::1009: Network is unreachable Restarting the connection and/or reloading the network card kernel module doesn't help. The only thing that helps is reboot. Clearly something is wrong with my system (everything else works fine), but I have no idea what exactly. I don't know how to reproduce this, but as I said, it happens every several days. My setup is a wireless router that is connected to the ISP via PPPoE. Any advice?

• Raid system fails to boot after moving from 2.6 kernel to 3.5

  - by user846226

  I'm running Gentoo Linux with a custom compiled kernel and I've just migrated from a 2.6 kernel to a 3.5. As my HD's are on RAID 0 mode I use a custom initrd file in order to be able to boot. While kernel 2.6 is able to boot without problems the new 3.5 compiled kernel fails to boot complaining about no block devices found. After taking a look at initrd.cpio contained scripts I can see the failure message is given by mdadm tool. Does anyone has a clue about that? Edit: this morning i noticed there was some kind of issue on my old initrd which works fine for 2.6 kernels, so created a new initrd which works fine and let me to boot into GNU/Gentoo Linux with same 3.5 bzImage. It could be an issue of mdadm, gonna check it. https://bugs.gentoo.org/show_bug.cgi?id=416081

• Howto align partitions in Linux + NetApp

  - by santisaez

  NetApp support has suggested us aligning partitions to improve performance, in short: starting sector must be divisible by 8. How can I move the start point in a misaligned partition -in production, with ext3- under Linux? A screenshot with a misaligned (start=63s) and aligned (start=64s) partition is available at: http://filesocial.com/lkwvvn2 (If anyone is interested in this topic, NetApp has a good document explaining performance issues in misaligned partitions, search for "tr-3747": Best Practices for File System Alignment in Virtual Environments.) I have tried using parted "resize + move" commands, but when moving start point a get this error: (parted) resize Partition number? 1 Start? [64s]? End? [419425019s]? 419425018 (parted) move Partition number? 1 Start? 65 End? [419425019s]? 419425019 Error: Can't move a partition onto itself. Try using resize, perhaps? Using fdisk 'b' command in expert mode ('move beginning of data in a partition') works, but it doesn't move the file system.. thanks!!

• Possible for linux bridge to intercept traffic?

  - by A G

  I have a linux machine setup as a bridge between a client and a server; brctl addbr0 brctl addif br0 eth1 brctl addif br0 eth2 ifconfig eth1 0.0.0.0 ifconfig eth2 0.0.0.0 ip link set br0 up I also have an application listening on port 8080 of this machine. Is it possible to have traffic destined for port 80 to be passed to my application? I have done some research and it looks like it could be done using ebtables and iptables. Here is the rest of my setup: //set the ebtables to pass this traffic up to ip for processing; DROP on the broute table should do this ebtables -t broute -A BROUTING -p ipv4 --ip-proto tcp --ip-dport 80 -j redirect --redirect-target DROP //set iptables to forward this traffic to my app listening on port 8080 iptables -t mangle -A PREROUTING -p tcp --dport 80 -j TPROXY --on-port 8080 --tproxy-mark 1/1 iptables -t mangle -A PREROUTING -p tcp -j MARK --set-mark 1/1 //once the flows are marked, have them delivered locally via loopback interface ip rule add fwmark 1/1 table 1 ip route add local 0.0.0.0/0 dev lo table 1 //enable ip packet forwarding echo 1 > /proc/sys/net/ipv4/ip_forward However nothing is coming into my application. Am I missing anything? My understanding is that the target DROP on the broute BROUTING chain will push it up to be processed by iptables. Secondly, are there any other alternatives I should investigate? Edit: IPtables gets it at nat PREROUTING, but it looks like it drops after that; the INPUT chain (in either mangle or filter) doesn't see the packet.

• What and all the areas of a Linux a PHP developer should know about? (Like just commands of it or something advanced)

  - by droidsites

  I've developed a website using PHP but I implemented it on Windows OS and hosted it on Windows server. I just searched the PHP job market to know the on-going technology requirement and to keep my knowledge up-to-date accordingly with the job market. I see more are asking for LAMP stack. I understand the sort of skills required for a developer in PHP and MySQL. But coming to the Linux and Apache what kind of the skills exactly companies expect from a developer? On what should I be focusing in case of Linux, Apache whilst developing my website using these LAMP stack? I am going to develop a new website and want it to be using LAMP. But I want to know what difference it makes? Why LAMP stack got more demand in the job market compared to WAMP ? Edit: Sorry I thought my question is creating confusion ... so I put my question in different words as What and all the areas of a Linux a PHP developer should know about? (Like just commands of it or something advanced) Note: I am Linux newbie

• Slower/cached Linux file system required

  - by Chopper3

  I know it sounds odd but I need a slower or cached filesystem. I have a lot of firewalls that are syslog'ing their data to a pair of Linux VMs which write these files to their 'local' (actually FC SAN attached) ext3-formatted disks and also forward the messages to our Splunk servers. The problem is that the syslog server is writing these syslog messages as hundreds, sometimes thousands, of tiny ~4k writes per second back to our FC SAN - which can handle this workload right now but our FW traffic's going to be growing by at least a factor of 5000% (really) in coming months and that'll be a pain for the SAN, I want to fix the root cause before it's a problem. So I need some help figuring out a way of getting these writes cached or held-off in some way from the 'physical' disks so that the VMs fire off larger, but less frequent, writes - there's no way of avoiding these writes but there's no need for it to do so many tiny ones. I've looked at the various ext3 options, setting noatime and nodiratime but that's not made much of a dent in the problem. Obviously I'm investigating other file systems but thought I'd throw this out in case others have the same problem in the future. Oh and I can't just forward these messages to Splunk, our firewall team insist they're in their original format for diag purposes.

• Delete a iptables chain with its all rules

  I have a chain appended with many rules like: > :i_XXXXX_i - [0:0] > -A INPUT -s 282.202.203.83/32 -j i_XXXXX_i > -A INPUT -s 222.202.62.253/32 -j i_XXXXX_i > -A INPUT -s 222.202.60.62/32 -j i_XXXXX_i > -A INPUT -s 224.93.27.235/32 -j i_XXXXX_i > -A OUTPUT -d 282.202.203.83/32 -j i_XXXXX_i > -A OUTPUT -d 222.202.62.253/32 -j i_XXXXX_i > -A OUTPUT -d 222.202.60.62/32 -j i_XXXXX_i > -A OUTPUT -d 224.93.27.235/32 -j i_XXXXX_i when I try to delete this chain with: iptables -X XXXX but got error like (tried iptables -F XXXXX before): iptables: Too many links. Is there a easy way to delete the chain by once command?

• Small maximum number of connections on a Linux router

  - by Eugene

  I have a Linux box acting as a router with no iptables or other firewall and no networking applications running on it, just pure router. I've put it in a test environment that generates many TCP connections, each having unique source and destination IP, and those connections go through this router. I'm observing that number of connections successfully created rise to approximately 500 and then no more connections can be created for several minutes, then another 100 connections can be created and there is another pause, and so on. If 10 connections for each source-destination pair are created, then maximum numbers go about 10 times up, so the problem is probably with many connections from different IPs. As traffic is simply routed, it doesn't have to do with number of file descriptors, iptables connection tracking and other things often proposed to check in similar cases. The box has plenty of free RAM and CPU, both NICs are gigabit. The kernel is 2.6.32. I've already tried increasing net.core.*mem_max, net.core.netdev_max_backlog and txqueuelen on both NICs, with completely no effect. What else should I check ? Is there some rate-limit in the kernel itself ?

• Linux iptables / conntrack performance issue

  - by tim

  I have a test-setup in the lab with 4 machines: 2 old P4 machines (t1, t2) 1 Xeon 5420 DP 2.5 GHz 8 GB RAM (t3) Intel e1000 1 Xeon 5420 DP 2.5 GHz 8 GB RAM (t4) Intel e1000 to test linux firewall performance since we got bitten by a number of syn-flood attacks in the last months. All machines run Ubuntu 12.04 64bit. t1, t2, t3 are interconnected through an 1GB/s switch, t4 is connected to t3 via an extra interface. So t3 simulates the firewall, t4 is the target, t1,t2 play the attackers generating a packetstorm thorugh (192.168.4.199 is t4): hping3 -I eth1 --rand-source --syn --flood 192.168.4.199 -p 80 t4 drops all incoming packets to avoid confusion with gateways, performance issues of t4 etc. I watch the packet stats in iptraf. I have configured the firewall (t3) as follows: stock 3.2.0-31-generic #50-Ubuntu SMP kernel rhash_entries=33554432 as kernel parameter sysctl as follows: net.ipv4.ip_forward = 1 net.ipv4.route.gc_elasticity = 2 net.ipv4.route.gc_timeout = 1 net.ipv4.route.gc_interval = 5 net.ipv4.route.gc_min_interval_ms = 500 net.ipv4.route.gc_thresh = 2000000 net.ipv4.route.max_size = 20000000 (I have tweaked a lot to keep t3 running when t1+t2 are sending as many packets as possible). The result of this efforts are somewhat odd: t1+t2 manage to send each about 200k packets/s. t4 in the best case sees aroung 200k in total so half of the packets are lost. t3 is nearly unusable on console though packets are flowing through it (high numbers of soft-irqs) the route cache garbage collector is no way near to being predictable and in the default setting overwhelmed by very few packets/s (<50k packets/s) activating stateful iptables rules makes the packet rate arriving on t4 drop to around 100k packets/s, efectively losing more than 75% of the packets And this - here is my main concern - with two old P4 machines sending as many packets as they can - which means nearly everyone on the net should be capable of this. So here goes my question: Did I overlook some importand point in the config or in my test setup? Are there any alternatives for building firewall system especially on smp systems?

  My server 2008 has mysql databases, SQL Server databases, and multiple websites. How do I back this information up? I have setup the dedicated server to have two 300GB hard drives and they are both mirrored. I want to make sure that I have a backup somewhere else as well. If it's not my home server, I don't mind backing up somewhere else either but I want to make sure I can restore it completely in case of a failure.

• Linux that restores itself on each reboot

  - by jettero

  I'm looking for methods and software to help create a variant of lubuntu that will restore itself to an install state and/or update on every boot. I'm thinking of doing things like putting the root filesystem on a squashfs and using unionfs and tmpfs to make root writable, but automagically restorable. I'm thinking of updating the squashfs with rsync. Perhaps there are other ways to approach the problem. Perhaps root needn't be writable at all. All thoughts welcome. The home dir would be writable in the usual way. The goal, if it matters, is a Linux that's simple to maintain from the home office, but that functions correctly for customers. We have some custom software that we wish for customers to be able to run trivially on equipment we provide. Ideally these devices would have a "restore to factory" function that would put it back the way we intended. If this is part of the normal boot cycle, so much the better. Why lubuntu? Personal preference for this application. It has a usable desktop, but doesn't take up much ram.

• linux kernel buffer memory is zero

  - by user64772

  Hi all. There are one qestion that i can`t find in google. I have many linux boxes mostly with SLES or openSUSE, diffrent versions and kernels. On some of them i faced with slow oracle transactions problem. It time to time problem and when i log in the box on that time i see that oracle blocked in kernel function sync_page # while :; do ps axo stat,pid,cmd,wchan | egrep '^D|^R'; echo --; sleep 5; done D 3483 hald-addon-storage: polling ide_do_drive_cmd Ds 4635 ora_dbw0_orcl sync_page Ds 4637 ora_lgwr_orcl sync_page Ds 4639 ora_ckpt_orcl sync_page D 11210 oracleorcl (LOCAL=NO) sync_page D 12457 [smtpd] sync_page R+ 12458 ps axo stat,pid,cmd,wchan - -- Ds 4635 ora_dbw0_orcl sync_page Ds 4637 ora_lgwr_orcl sync_page Ds 4639 ora_ckpt_orcl sync_page D 11210 oracleorcl (LOCAL=NO) sync_page R+ 12501 ps axo stat,pid,cmd,wchan - -- Ds 4635 ora_dbw0_orcl sync_page Ds 4637 ora_lgwr_orcl sync_page Ds 4639 ora_ckpt_orcl sync_page D 11210 oracleorcl (LOCAL=NO) sync_page R+ 12535 ps axo stat,pid,cmd,wchan - -- Ds 4635 ora_dbw0_orcl sync_page Ds 4637 ora_lgwr_orcl sync_page Ds 4639 ora_ckpt_orcl sync_page D 11210 oracleorcl (LOCAL=NO) sync_page R+ 12570 ps axo stat,pid,cmd,wchan - -- so i think that box is run out of memory for disk buffers but memry is fine total used free shared buffers cached Mem: 4149084 3994552 154532 0 0 2424328 -/+ buffers/cache: 1570224 2578860 Swap: 3148700 750696 2398004 i think that this is the problem, buffer is zero and we must write directly to disk, but why buffer is zero ? - i try to google it and find nothing - is anyone can help ?

• Drop caches in Linux

  - by BerserkEVA

  I have an embedded Geode-based application server with 512MB RAM and I'm about to try to maximize free memory during applications workload, which uses MySQL database 5.5 with InnoDB quite aggressively. As part of the whole optimization I'd want to introduce echo 1 > /proc/sys/vm/drop_caches sleep 5 echo 0 > /proc/sys/vm/drop_caches in crontab. How often is it safe to execute something like this? Any other observation/suggestion is welcome.

• sudo rejects password that is correct

  - by Ryan

  sudo (Which I have configured to ask for a password) is rejecting my password (as if I mis-typed it) I am absolutely not typing it incorrectly. I have changed the password temporarily to alphabetic characters only, and it looks fine in plaintext, in the same terminal. I have my username configured thus: myusername ALL=(ALL) ALL I am using my password, NOT the root password, which are distinct. Just to be sure, I've tried both (even though I know the root password is not what I should use) - neither work. I have added myself to the group 'wheel' additionally, and included the following line: %wheel ALL=(ALL) ALL I'm kind of at the end of my rope here. I don't know what would cause it to act as though it was accepting my password, but then reject it. I have no trouble logging in with the same password, either at terminal shells, or through the X11 login manager.
