  • why won't php 5.3.3 compile libphp5.so on redhat ent

  • Does lshw list the "factory" speed of a memory module or the effective speed and how to find the former?

    - by Panayiotis Karabassis
    I hope I phrased this correctly. lshw gives: description: DIMM Synchronous 400 MHz (2.5 ns) product: M378B5773CH0-CH9 vendor: Samsung physical id: 0 slot: DIMM0 size: 2GiB width: 64 bits clock: 400MHz (2.5ns) And indeed the memory speed is set is set to 800MHz in the BIOS, which I think makes sense since it is a double rate. On the other hand, Googling strongly suggests that to this product number corresponds the PC3-10600 type, which is 1333MHz, not 800MHz. And this seems to be confirmed in the BIOS, where if I select Auto for memory bus speed, 1333MHz is selected "based on SPD settings". However in the latter case, the computer does not boot, i.e. the kernel panics, complaining that something attempted to kill the Idle process. So, I am I am beginning to suspect that I have been given defective memory, the technician that installed saw this, and lowered the bus speed. Is this a possibility?

  • How do you backup your own files? [on hold]

    - by Antonis Christofides
    I'm a system administrator and I use rsnapshot to backup some servers, duplicity for some others. Both work fine, each one with advantages and disadvantages. Despite that, I am at a loss on how to backup my own private files. I'd use duplicity to automatically backup my files to a remote server; but the problem is that once in a while I must do a full backup. My emails and important files are 9G, and I expect this to increase. Uploading through aDSL at 1Mbit would be 20 hours. Too much. rsnapshot doesn't require periodic full backups (only the first time), but it must be running on the remote server and have a means to connect to my computer; if the server is compromised (or simply if the NSA decides to use it), my own machine is also compromised. Not good. The only solution I've come up with is use encfs, use unison to synchronize the files to a remote server, and use duplicity or rsnapshot on the remote server to backup these files. In that case, the question is whether I can sync the files on many computers; is it possible for encfs to be used with the same key on many computers? I also think that if I append one character to the unencrypted file, its encrypted encfs counterpart might change a lot, so that incrementals with duplicity would be less efficient—but not a big deal. Maybe also, when I need to restore a file, finding the correct file to restore could be a pain, because of filename encryption. I wonder whether there is any other possibility that I've overlooked. Maybe I'm asking too much for my personal use, and I should settle with an external disk?

  • How to increase acpiphp slots?

    - by Eil
    Hi, Oh RHEL 5.5, there are 31 ACPI PCI hotplug slots by default: acpiphp: Slot [1] registered ... acpiphp: Slot [31] registered Is there a way to increase this number? I haven't been able to find an argument to supply to modprobe, or a sysctl knob to tweak, but I know there must be ways to get more slots based on some Google sleuthing. (For the curious, this is just preliminary experimentation to see how many virtual disks I can hot-add to a running KVM guest.)

  • Tuning MySQL to consume less memory

    - by Alex
    I have a VM which has 2GB Ram, (full specs) And I am setting up a site which has one table in particular with over a million records. There's little or no usage of this particular database (perhaps once or twice a day) but simply running mysql grinds the whole server to a halt. I've looked through the top results but nothing is really denting the CPU however the memory seems to be the issue. The site isnt even live of taking requests yet. the memory situation looks like this: # free -m total used free shared buffers cached Mem: 2006 1880 126 0 3 53 -/+ buffers/cache: 1823 183 Swap: 2047 345 1702 Are there any good pointers to tune mysql to stop hogging the system memory? Thanks very much EDIT: (requested by 8bit): http://tny.cz/b41a0b12

  • NIC is receiving, but not transmitting at all?

    - by Shtééf
    I'm trying to fix a very strange problem remotely on a machine at a customer site. The machine is a Dell PowerEdge, I believe a 1950 (haven't verified, but the lspci output matches specs I found.) The machine has two similar NICs, identified as Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12) by lspci, and using the bnx2 driver. (I suspect these are on-board and on the same controller, which is what I'm accustomed to for this type of machine.) The primary interface eth0 works perfectly, and is in fact how I am ssh'd in. However, the secondary interface eth1 is not transmitting. I can see this in ifconfig output, for example, where the TX field is always 0. However, it is receiving, and tcpdump shows ARP requests coming from the ISP's gateway on the other side. The interface is physically connected to a Siemens BSTU4 modem, configured by the ISP. The link is properly set to 10MBps and full duplex, without negotation, as the ISP requested. A small /30 subnet is configured. For the sake of anonimity, let's say the machine is 3.3.3.2/30, and the ISP's gateway .1. The machine has no firewall settings whatsoever. Even running something like arping -I eth1 3.3.3.1, and running tcpdump alongside, shows no traffic whatsoever being transmitted on the interface. (But the other side keeps steadily sending ARP requests, and that is all that can be seen.) What could be causing this? Here's some output, anonymized, which may hopefully help: $ ethtool eth1 Settings for eth1: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: Not reported Advertised auto-negotiation: No Speed: 10Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: off Supports Wake-on: d Wake-on: d Link detected: yes $ ip link show eth1 3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:15:c5:xx:xx:xx brd ff:ff:ff:ff:ff:ff $ ip -4 addr show eth1 3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 inet 3.3.3.2/30 brd 3.3.3.3 scope global eth1 $ ip -4 route show match 3.3.3.0/30 3.3.3.0/30 dev eth1 proto kernel scope link src 3.3.3.2 default via 10.0.0.5 dev eth0

  • Setting umask for all users

    - by Yarin
    I'm trying to set the default umask to 002 for all users including root on my CentOS box. According to this and other answers, this can be achieved by editing /etc/profile. However the comments at the top of that file say: It's NOT a good idea to change this file unless you know what you are doing. It's much better to create a custom.sh shell script in /etc/profile.d/ to make custom changes to your environment, as this will prevent the need for merging in future updates. So I went ahead and created the following file: /etc/profile.d/myapp.sh with the single line: umask 002 Now, when I create a file logged in as root, the file is born with 664 permissions, the way I had hoped. But files created by my Apache wsgi application, or files created with sudo, still default to 644 permissions... $ touch newfile (as root): Result = 664 (Works) $ sudo touch newfile: Result = 644 (Doesn't work) Files created by Apache wsgi app: Result = 644 (Doesn't work) Files created by Python's RotatingFileHandler: Result = 644 (Doesn't work) Why is this happening, and how can I ensure 664 file permissions system wide, no matter what creates the file? UPDATE: I ended up finding a cleaner solution to this on a per-directory basis using ACLs, which I describe here.

  • How to search a text file for strings between two tokens in Ubuntu terminal and save the output?

    - by Blue
    How can I search a text file for this pattern in Ubuntu terminal and save the output as a text file? I'm looking for everything between the string "abc" and the string "cde" in a long list of data. For example: blah blah abc fkdljgn cde blah blah blah blah blah blah abc skdjfn cde blah In the example above I would be looking for an output such as this: fkdljgn skdjfn It is important that I can also save the data output as a text file. Can I use grep or agrep and if so, what is the format?

  • volume group disappeared after xfs_check run

    - by John P
    EDIT** I have a volume group consisting of 5 RAID1 devices grouped together into a lvm and formatted with xfs. The 5th RAID device lost its RAID config (cat /proc/mdstat does not show anything). The two drives are still present (sdj and sdk), but they have no partitions. The LVM appeared to be happily using sdj up until recently. (doing a pvscan showed the first 4 RAID1 devices + /dev/sdj) I removed the LVM from the fstab, rebooted, then ran xfs_check on the LV. It ran for about half an hour, then stopped with an error. I tried rebooting again, and this time when it came up, the logical volume was no longer there. It is now looking for /dev/md5, which is gone (though it had been using /dev/sdj earlier). /dev/sdj was having read errors, but after replacing the SATA cable, those went away, so the drive appears to be fine for now. Can I modify the /etc/lvm/backup/dedvol, change the device to /dev/sdj and do a vgcfgrestore? I could try doing a pvcreate --uuid KZron2-pPTr-ZYeQ-PKXX-4Woq-6aNc-AG4rRJ /dev/sdj to make it recognize it, but I'm afraid that would erase the data on the drive UPDATE: just changing the pv to point to /dev/sdj did not work vgcfgrestore --file /etc/lvm/backup/dedvol dedvol Couldn't find device with uuid 'KZron2-pPTr-ZYeQ-PKXX-4Woq-6aNc-AG4rRJ'.

  • USER_LOGIN audit log with incorrect auid value?

    - by hijinx
    We have a CentOS 6.2 x86_64 system that's logging what looks to be erroneous audit information. We were receiving alerts for failed logins by a user who wasn't actually trying to log in. After some diagnosis, we figured out that the source of the events is our tool that periodically checks to see if SSH is answering. When that happens, we see this log this entry: type=USER_LOGIN msg=audit(1340312224.011:489216): user pid=28787 uid=0 auid=501 ses=8395 subj=unconfined_u:system_r:sshd_t:s0-s0:c0.c1023 msg='op=login acct=28756E6B6E6F776E207A01234567 exe="/usr/sbin/sshd" hostname=? addr=127.0.0.1 terminal=ssh res=failed' This is the entry we get whenever there is an incomplete ssh connection, but usually the auid is the same as the ses= value. For some reason, on this system, it's using a particular user's auid, regardless of the login user. For example, ssh'ng to this system as [email protected] and cancelling before providing a password generates this error. Attempting to log to an unrelated account with a bogus password will also create an entry with the incorrect auid value.

  • Symlink across local volumes in webroot?

    - by geerlingguy
    I am looking for a good short-term solution to storage space concerns on my website. Currently, I have all uploaded files (flash video, images, etc.) inside the 'files' directory in my web root (/home/account/public_html/files). That directory is located on my high-speed main hard drive (a 15k SCSI drive). I have another drive with much more capacity, but spinning at 10k rpm (so still fast, but not as good for random reads/writes as the main drive. The entire drive is mounted at /backup Right now I'm just using it as a backup volume. I would like to create a symlink from my /home/account/public_html/files folder to /backup/files, and have all files reside on the second drive. However, if someone accesses a file at http://www.example.com/files/filename.jpg, would it still work if I symlinked to the second drive? (Basically, would Apache/PHP automatically know to follow the symlink for that directory?).

  • DNS propagation

    - by Paddington
    I have 1 primary DNS server (ns1.mydomain.com) running on Fedora and 2 secondary ones (ns2 and ns3). DNS changes made on my web servers first goes to the primary name server and then propagates to the secondary servers. After making a DNS change on a domain on the web server, I can't see the new dns information on my ns1 when I perform: dig @ns1 A blahblah.com I then went to the master records on the names server (uses named) in the directory /var/named/run-root/var/named/masters and I see the A record has been updated appropriately. Tailing the logs /var/log/messages is not showing any errors. What could be the issue?

  • How do I stop ssh-agent from forgetting my password after I login to the screen session from SSH?

    - by Shwouchk
    I have a screen session open in an lxterminal window. If I SSH somewhere, the first time it happens, an ssh-agent window opens and asks me for my private key passphrase, and after that ssh goes right on. If I log in from outside to this machine and attach to the screen session however, ssh-agent now asks me every time I connect for my passphrase, in the terminal. Is there a way to avoid this and to let it continue using the X agent, or at least to have the non-X agent remember the passphrase?
