I want to connect to a l2tp server from centos.
by Eliezer Croitoru 22 Mar '17

22 Mar '17

I have a server currently connecting to a pptp remote server. This server(lns\lac) has the option for pptp connections and l2tp connections. The l2tp connections are not using ipsec encryption at all. I have seen couple guides\tutorials on the internet: - https://raymii.org/s/tutorials/IPSEC_L2TP_vpn_on_CentOS_-_Red_Hat_Enterpris… - https://wiki.archlinux.org/index.php/L2TP/IPsec_VPN_client_setup But all the guides that I have found are using ipsec with "secret". On ubuntu there is a gui applet that helps setting these kind of connections up but I am working with a CentOS server and not Ubuntu desktop. If someone used l2tp the same way I want to use on CentOS 7 please give me some advice. If you have a guide which might help me I will be more then happy to see this one. Thanks, Eliezer

PV AMI for CentOS 7
by Jo Rhett 20 Oct '15

20 Oct '15

Is there any chance we could get a PV AMI for CentOS 7 to match the HVM version at https://aws.amazon.com/marketplace/pp/B00O7WM7QW/ref=srh_res_product_title?… We have prepurchased reserved instances based on older PV machines (m1, c1, etc) It would be very very helpful to have a PV AMI so we could migrate to CentOS 7 on those image types. https://bugs.centos.org/view.php?id=9499 <https://bugs.centos.org/view.php?id=9499> -- Jo Rhett Net Consonance : net philanthropy to improve open source and internet projects.

ExecShield in C6 or C7 kernels?
by Fred Smith 05 Oct '15

05 Oct '15

I'm trying to figure out if the stock kernels for Centos-6 and/or Centos-7 have ExecShield compiled in, and if so, if it is turned on by default. On my local C7 box I've been looking at/for indicators without a lot of success: /usr/lib/sysctl.d/00-system.conf. does not mention ExecShield at all. /proc/sys/kernel has no entries for exec_shield no mention of execshield in any of the files in /etc/grub.d So, as far as I can see, there are no settings that I would expect to force ExecShield to an ON setting. I DO see, in /proc/sys/kernel, a file named randomize_va_space, and it contains a value of "2". I've been googling (well, actually DuckDuckGo-ing) and most of the articles I find regarding ExecShield are 3-10 years old. I'd appreciate pointers/guides/info on ExecShield in C6 or C7. thanks in advance!

CentOS-6.7 Passing delayed shutdown via ssh command line argument?
by James B. Byrne 01 Oct '15

01 Oct '15

If I log into a host via ssh from my workstation then I can enter this: shutdown -r +90& and log out. The shutdown command will continue in effect and will activae 90 minutes later. However, if I do this instead: ssh -t host.domain.tld 'shutdown -r +90&' then the shutdown command does not remain in effect. Why is this so and is there some way to achieve this? -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail James B.

sendmail config finding wrong relay
by Jerry Geis 30 Sep '15

30 Sep '15

Hi all, I set my sendmail.mc file to have a SMART_HOST entry of mail.xyz.com I do "make" and "service sendmail restart" ... I should be good, but no. :) If I do "host mail.xyz.com" I get the correct address and if I "telnet mail.xyz.com 25" I get a connection. however when I do a test mail - its trying to RELAY to another host. I thought SMART_HOST was the only one it would try to relay to? yes there is only one SMART_HOST in my file, and sendmail.cf shows the correct name. How do I tell what is happening here? the maillog only shows it trying to relay to the wrong host, not the one I entered. Any thoughts? Thanks, Jerry

CentOS 6 - Support for CanoScan LiDE 210
by Meikel 30 Sep '15

30 Sep '15

Hi folks, for some time I used a HP 2840 AiO device, connected via LAN, to scan documents. As scanning application I use xsane. I want to replace that HP scanner by a CanoScan LiDE 210. # LANG="" yum info libsane-hpaio ... Installed Packages Name : libsane-hpaio Arch : x86_64 Version : 3.14.6 Release : 3.el6 Size : 148 k Repo : installed From repo : base Summary : SANE driver for scanners in HP's multi-function devices URL : http://hplip.sourceforge.net/ License : GPLv2+ Description : SANE driver for scanners in HP's multi-function devices (from HPOJ). Now I connected CanoScan LiDE 210 Scanner via USB cable to my CentOS 6 workstation. # dmesg | tail --lines=15 ... usb 3-1: new high speed USB device number 8 using xhci_hcd usb 3-1: New USB device found, idVendor=04a9, idProduct=190a usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 3-1: Product: CanoScan usb 3-1: Manufacturer: Canon usb 3-1: configuration #1 chosen from 1 choice ... After opening xsane it seems to be connected to the HP Scanner. I can not find any options for choosing another scanner device. From http://www.sane-project.org/sane-mfgs.html I can see that CanoScan LiDE 210 is supported by genesys 1.0-63. From my understanding on CentOS the genesys backend is included in sane-backends: # LANG="" yum info sane-backends ... Installed Packages Name : sane-backends Arch : x86_64 Version : 1.0.21 Release : 3.el6 Size : 4.4 M Repo : installed From repo : anaconda-CentOS-201410241409.x86_64 Summary : Scanner access software URL : http://www.sane-project.org License : GPLv2+ and GPLv2+ with exceptions and Public Domain Description : Scanner Access Now Easy (SANE) is a universal scanner interface. The : SANE application programming interface (API) provides standardized : access to any raster image scanner hardware (flatbed scanner, : hand-held scanner, video and still cameras, frame-grabbers, etc.). The sane-backends is installed, but I can not "see" the scanner: # scanimage -L device `hpaio:/net/HP_Color_LaserJet_2840?zc=NPI9AC264' is a Hewlett-Packard HP_Color_LaserJet_2840 all-in-one I have no idea what I can do now. It is not clear to me if sane-backends package really includes the required genesys 1.0-63 version. Any help to make the new scanner work is appreciated. Regards, Meikel

Question maybe off topic
by Jerry Geis 29 Sep '15

Is there something in CentOS/linux that would take a single input in my case RS232 port and deliver that to two connecting network ports? So two devices can get the single port data. Thanks, Jerry

[OT] linux on a PPC (mac mini)
by wwp 29 Sep '15

29 Sep '15

Hello there, complete off-topic, sorry about this, but my former idea was to install a CentOS on an old mac mini (PPC!). Disappointed to see that PowerPC is not a supported architecture and that non ARM or Intel architecture are not managed by recent distros.. :-(. Searching the web, I see very few possibilities to install a recent (I need gnome2) GNU/Linux distro on such hardware. I gave Linux MintPPC 11 (http://www.mintppc.org/content/list-macs) a try, but the netinstall iso simply fails in installing a boot loader that conserves the original OS/X partition even after many tries and workarounds. Any hint or experience would be welcome? Regards, -- wwp

Hello, I have installed CentOS7 and found some of the Chinese html web pages hosted on the CentOS machine cannot display normally.

Mate-update breaks locale

29 Sep '15

Hello All, today's Mate-updates seem to have removed our nl_be locale. We run Mate desktop on some 15 Centos7 laptops. Not so big a deal, we can easily switch to nl_nl or people would still figure it out in English. But maybe for other, not so common locales, you might want to check before updating. Greetings, Johan

httpd userdir problem
by Timothy Murphy 28 Sep '15

28 Sep '15

I'm running httpd-2.4.6-31.el7.centos.1.x86_64 under CentOS-7 (kernel 3.10.0-229.14.1.el7.x86_64). I cannot get the httpd userdir facility working; when I try to access localhost/Menloe I get the message "You don't have permission to access /Menloe on this server." I see in /var/log/httpd/error_log "Symbolic link not allowed or link target not accessible: /var/www/html/Menloe" while in /var/log/httpd/access_log I see "GET /Menloe HTTP/1.1" 403 208 In /etc/httpd/conf.d/userdir.conf I have UserDir public_html and <Directory "/home/*/public_html"> AllowOverride All Require all granted Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec Require method GET POST OPTIONS </Directory> The directory ~/public_html/Menloe/ is owned by me, and has permissions drwxr-xr-x. I wonder if anyone has met this problem? Or if anyone is using the apache userdir facility in CentOS 7? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

Is this a bug in CentOS-7 BackupPC?

27 Sep '15

When I try to start BackupPC with "sudo systemctl restart backuppc" on my CentOS-7 server (running kernel 3.10.0-229.14.1.el7.x86_64) I get the following error in /var/log/BackupPC/LOG 2015-09-26 13:58:14 Reading hosts file 2015-09-26 13:58:14 unix bind() failed: No such file or directory This message occurs in the Perl script /usr/share/BackupPC/bin/BackupPC : my $sockFile = "/var/run/BackupPC/BackupPC.sock"; unlink($sockFile); if ( !bind(SERVER_UNIX, sockaddr_un($sockFile)) ) { print(LOG $bpc->timeStamp, "unix bind() failed: $!\n"); exit(1); } As far as I can see (I'm no guru) this is trying to open a unix socket with the name /var/run/BackupPC/BackupPC.sock . There is no directory /var/run/BackupPC/ on my server. When I create this, setting backuppc.apache as owner, and run "sudo systemctl restart backuppc" I see in /var/log/BackupPC/LOG that BackupPC has (at long last) started -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

Samba Enterprise from Sernet no longer free
by Robert Moskowitz 26 Sep '15

26 Sep '15

http://www.samba.plus/ Currently this, other than rolling your own, this appears the only way to have a Samba AD on Centos. Later in the Samba 4.3 effort, MIT Kerberos is suppose to be supported so it MAY be easier to roll your own in a while, but until then, things are as they are. I am rethinking my efforts to develop a ARM based AD. I may just fall back (as everyone else) to just an NT style PDC.

x2go on CentOS6

25 Sep '15

Has anyone managed to get the x2go server working on CentOS 6.7? I started testing x2go from EPEL under 6.6, and it worked well. Then I didn't use it in 6 months plus, eventually upgraded the machine to 6.7, and it's no longer working. Both Windows and Linux clients error out with "Connection failed. 0: Event not found."

php DOMDocument and entities
by Alice Wonder 24 Sep '15

This is not CentOS specific but I hope someone here knows so I do not have to subscribe to another list. I'm using php DOMDocument to create an XSL that needs a non-breaking space between two values. Basically: $xslvalueof = $dom->createElement('xsl:value-of'); $xslvalueof->setAttribute('select', '../@month'); $caption->appendChild($xslvalueof); $nbsp = $dom->createTextNode(' '); $caption->appendChild($nbsp); $xslvalueof = $dom->createElement('xsl:value-of'); $xslvalueof->setAttribute('select', '../@year'); $caption->appendChild($xslvalueof); That's what I am trying to do. createTextNode() however tries to protect the users, and automatically turns any & into & So I tried $nbsp = $dom->createEntityReference('#160'); That however gives a dom error, it seems createEntityReference only works with named entities. $nbsp = $dom->createEntityReference('nbsp'); works, but then I would have to modify the DTD for both XSL and the target XML because neither have nbsp defined. How can I create the literal string ' ' using DOMDocument as a text node between two other nodes? This is driving me nuts. I could I suppose put it inside a span &nbsp = $dom->createElement('span', ' '); That works but is hackish. It seems to work though by generating the actual UTF8 character itself. I really wish the XML spec itself had named entities for the various whitespace characters that tend to get eaten by XML parsers if not done as a numbered entity. Ah well. Using   works just fine when the XSL is a text file. It is dynamically creating it via DOMDocument where I have a problem. Thanks for any suggestions. -- -=- Sent my from my laptop, may not be able to respond timely

Bug in init scripts for ipset?
by tony＠softins.co.uk 24 Sep '15

24 Sep '15

I've just started experimenting with ipset under CentOS 6, and have found what appears to be a bug (or poor design) in the init scripts for ipset, /etc/rc.d/init.d/ipset In stop(), save() and status(), it does lsmod to check for the existence of the ip_set module. If the module is not found, it exits without performing any action. This doesn't take account of a kernel where the ip_set code is compiled in instead of being a loadable module. An example would be my CentOS 6 virtual machine at Linode. It has a Linode-compiled kernel 4.1.0 with no separately-loaded modules. It certainly supports ipset, as I have successfully tried some test rules. However, I wondered why giving the command "service ipset save" didn't result in /etc/sysconfig/ipset being written, and discovered the cause I described above. Surely there should be a better way of determining whether the kernel includes ipset support than just looking for a module?

Logrotate problems
by Andrew Holway 24 Sep '15

24 Sep '15

Hi Y'all, We have nginx set up and we are having problems with logrotate. The permissions and users do not seem to be any different from other machines that are working ok however the /var/log/nginx does have a directory in there that we are using to collect some special log stuff. Could this subdirectory be interfering with the logrotate process? ta Andrew [root@ ~]# logrotate -d /etc/logrotate.d/nginx reading config file /etc/logrotate.d/nginx Handling 1 logs rotating pattern: /var/log/nginx/*log after 1 days (10 rotations) empty log files are not rotated, old logs are removed considering log /var/log/nginx/access.log error: skipping "/var/log/nginx/access.log" because parent directory has insecure permissions (It's world writable or writable by group which is not "root") Set "su" directive in config file to tell logrotate which user/group should be used for rotation. considering log /var/log/nginx/error.log error: skipping "/var/log/nginx/error.log" because parent directory has insecure permissions (It's world writable or writable by group which is not "root") Set "su" directive in config file to tell logrotate which user/group should be used for rotation.

amanda-client does not recognise 'dump'
by Tom Robinson 24 Sep '15

CentOS Linux release 7.1.1503 (Core) amanda-3.3.3-13.el7.x86_64 amanda-client-3.3.3-13.el7.x86_64 amanda-libs-3.3.3-13.el7.x86_64 dump-0.4-0.22.b44.el7.x86_64 Hi, I have been using amanda backup for quite a long time now. I'm busy migrating some older hosts to CentOS 7 but have found that the available amanda packages (see above) have not been compiled on a host that has the 'dump' program installed. Is this just an oversight or are we trying to not use 'dump' anymore? If the former, who is responsible for re-compiling this on a host that has 'dump' installed. Please see http://archives.zmanda.com/amanda-archives/viewtopic.php?t=7390 for more details Kind regards, Tom -- Tom Robinson IT Manager/System Administrator MoTeC Pty Ltd 121 Merrindale Drive Croydon South 3136 Victoria Australia T: +61 3 9761 5050 F: +61 3 9761 5051 E: tom.robinson(a)motec.com.au
