Gateway question
by Levente Birta 11 Aug '16

11 Aug '16

Hi There is a Centos 7 up-to-date box with 2 interfaces, let's say 192.168.1.12 - enp2s0, 192.168.1.13 on enp3s0. Default gateway on enp2s0. The gateway is pfsense, IP is 192.168.1.1 with 2 WAN connections On the gateway the outgoing traffic is routed by source ip to different WAN, 192.168.1.12 to WAN1 and 192.168.1.13 to WAN2 On the centos box are set all the route and routing rules: route-enp2s0: 192.168.1.0/24 dev enp2s0 src 192.168.1.12 table t2 default via 192.168.1.1 dev enp2s0 table t2 route-enp3s0: 192.168.1.0/24 dev enp3s0 src 192.168.1.13 table t3 default via 192.168.1.1 dev enp3s0 table t3 rule-enp2s0: from 192.168.1.12/32 table t2 to 192.168.1.12/32 table t2 rule-enp3s0: from 192.168.1.13/32 table t3 to 192.168.1.13/32 table t3 All work when I add #route add default gw 192.168.1.1 dev enp3s0 And that way I have : # ip route show default via 192.168.1.1 dev enp3s0 default via 192.168.1.1 dev enp2s0 169.254.0.0/16 dev enp2s0 scope link metric 1002 169.254.0.0/16 dev enp3s0 scope link metric 1003 192.168.1.0/24 dev enp2s0 proto kernel scope link src 192.168.1.12 192.168.1.0/24 dev enp3s0 proto kernel scope link src 192.168.1.13 But how can I add achieve this only with ip route command ... without route? Can I add this in any config files (ex: route-enp2s0)? Thanks -- Levi

XRDB not in our centos6.8 build
by Dan Hyatt 11 Aug '16

11 Aug '16

I am a bit baffled on this. We recently rebuilt all our servers to CentOS release 6.8 (Final) from a prior 6.x centos release. We ran into a couple of problems such as Java not working (just had to yum install java). It was installed, but unable to create a java machine, until I yum install java solved the problem. But now a user (the big boss) is receiving xrdp errors. And it appears that xrdp is not installed on these newly built servers. I googled xrdp and was unable to decipher if it is needed in our environment (we use sas which does use X11 graphics on the servers to export graphs). If it is needed, wondering why it not included in the groups we have always used for kickstart. When would I need xrdp? or is it one of the leftovers here from a bygone era? Thanks for your response.

C7 Backup problem
by Alessandro Baggi 10 Aug '16

10 Aug '16

Good morning list, I've a question about backup performed with bacula. I manage a DELL server (dedicated on provider) with C7. I use bacula as backup system with volumes on disk. System performs mon-sat incremental backups and Sun full backup at 03.00 AM. I've another pool (named update) where I performs backup before each software update. Storage is on and external disk 2.5' of 1TB. Yesterday, I've applied centos update and I've performed a full backup before apply updates. Job done. After several hours, I got my disk unmounted and disconnected due to disk error (seems that this disk is failing) and was unable to remount disk. Rebooting system, the disk was mounted correctly. This morning I've checked if something happened. Backup performed and disk mounted without errors but I've noticed a strange behaviour. My incremental backup is large as last full backup (performed on sunday). This is the last jobs performed. 76 | backup-fd | 2016-08-07 03:04:44 | B | F | 191,040 | 7,975,649,059 | T | | 77 | backup-fd | 2016-08-08 03:04:57 | B | I | 44 | 44,593,988 | T | | 78 | backup-fd | 2016-08-08 09:52:57 | B | F | 191,024 | 7,978,295,072 | T | | 79 | backup-fd | 2016-08-08 12:10:31 | B | F | 0 | 0 | A | | 80 | backup-fd | 2016-08-09 03:05:03 | B | I | 191,024 | 7,978,337,100 | T Job with id 79 was aborted due to disk failure. Why, if I have a job full performed on sunday, on monday I got an incr job with the same size? Seems to be that the last incremental job was performed without considering the last full backup. I've checked log but there aren't errors. Thanks. Alessandro.

Maybe OT - Centos 5 SATA JMicron JMB361 SATA
by Ken Smith 10 Aug '16

10 Aug '16

Hi All, I know Centos 5 is almost EOL and all this is old but.... I'm helping a colleague who has moved a Centos 5 install on an IDE disk to system with a Foxconn M'board. His idea is to use the SATA interface that's on the Foxconn. The thing boots OK and then gets into a loop trying to start the interfaces to the SATA disks. Oceans of stuff like this in /var/log/messages Aug 7 04:23:32 filestore kernel: ata1: hard resetting link Aug 7 04:23:32 filestore kernel: ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310) Aug 7 04:23:32 filestore kernel: ata1.00: configured for UDMA/33 Aug 7 04:23:32 filestore kernel: ata1.01: configured for UDMA/33 Aug 7 04:23:32 filestore kernel: ata1: EH complete Aug 7 04:24:02 filestore kernel: ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen Aug 7 04:24:02 filestore kernel: ata1.00: cmd 25/00:08:00:88:e0/00:00:e8:00:00/e0 tag 0 dma 4096 in Aug 7 04:24:02 filestore kernel: res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) Aug 7 04:24:02 filestore kernel: ata1.00: status: { DRDY } I have limited the SATA speed to 1.5G with a kernel param in Grub to see if that helps. After a few hours the thing seems to settle down and can see this cat /proc/partitions | grep sd 8 0 1953514584 sda 8 16 1953514584 sdb 8 32 1953514584 sdc But the devices are non-functional. eg:- smartctl -a /dev/sda Smartctl open device: /dev/sda failed: No such device and fdisk /dev/sda Unable to open /dev/sda So I reckon the JMicron JMB361 controller [02:00.0 SATA controller: JMicron Technology Corp. JMB361 AHCI/IDE (rev 02)] is not something that Centos 5 is very keen on. Its loaded the ahci module for it uname says Linux filestore 2.6.18-411.el5 #1 SMP Mon Jul 11 18:16:41 CDT 2016 i686 i686 i386 GNU/Linux This thread -> https://bugzilla.redhat.com/show_bug.cgi?id=462425 <- suggests that a fix may have been backported from 2.6.27 Does this look familiar to anyone? And is there a remedy or would I be best to swap in a better SATA controller in there? Suggestions??

Regarding using CentOS on Commercial Appliance
by Akshat Kakkar 10 Aug '16

10 Aug '16

Hi All!I am builiding a firewall appliance based on CentOS. I am using CentOS as it is with some packages removed and some configuration done to security harden the appliance. Over and above this I will be installing Apache Web Server and Tomcat to run my web application which will give a web interface to configure the iptables in the appliance. There is no development done in iptables. It is used as available in its latest version online. As Tomcat will be running as non-root so it cant actually write the iptables rule. For writing iptables rules I will be using C++ executables with SUID bit set.Once this will be done, I am planning to Commercialise it. Am I allowed to do so without revealing my web application code and the C++ executable code (for iptables)? I know all the CentOS packages, etc. might fall in GPL and as a result I should be supplying source code of all the packages in CentOS. What else is expected from me? Thanks.

ssh & ksh question
by m.roth＠5-cent.us 10 Aug '16

10 Aug '16

I need to run a report, source file on system 1, on system 2. I'd like to do this in one script, not have a second script to run it. Now cat script | ssh system2 works fine. But no matter what I've tried, it gags on ssh system2 <<EOF blah, blah EOF. Mostly, I have a multiline awk script in the script, with \ at the end of each line... *but* I think it's seeing "\n" as an eol, and complaining, of course. Suggestions? mark

Eclipse rpms
by Gordon Messmer 10 Aug '16

10 Aug '16

I use Fedora for most workstations, so I've only just noticed that CentOS and EPEL don't appear to have packages for eclipse. All of the Google search results I've seen that contain a process for installation merely document downloading the tarball from eclipse.org. Is there a yum repo for these packages? Does CentOS not rebuild the Red Hat software collections? https://access.redhat.com/discussions/933183

Centos 7 - how to resurrect /dev/fb0? Or an alternative to fbterm for 256 color tty terminals?
by Nick Cammorato 10 Aug '16

10 Aug '16

Hi Everyone! I've been trying to rediscover the lost art of appliance-ification. SystemD is actually pretty amenable to masking tty1 and spawning a program instead of login which makes a config console a rather easy thing to do (mostly). Have that bit done, no problem. Happily spawning a rather locked down program. However, you seem to be limited in terms of color palette, creating a new take on the classic how do you get a 256 color terminal on a tty problem (the related, how do you change the terminal resolution problem seems solved via boot param). The old way(that I used) was to just wrap whatever in fbterm, but fbterm is missing. I can compile and package and install it no problem, but apparently there's no longer a framebuffer for it to attach to - /dev/fb0 is gone - so it can't actually run. There doesn't appear to be anything that would create /dev/fb0 either - It looks like nothing was compiled into the default kernel. The vga16fb module is available if you install a xen kernel from centos-xen, but it's 16 colors. vmwgfx doesn't seem to make a framebuffer either, and it's questionable if that'll work across both virtualbox and vmware in any case. An alternative would be to use xvfb or some such but that's super overweight. So, finally, a question - does anyone know how you solve this today? Best, --Nick Cammorato

centos 7- boot doesn't wait for startup script to complete
by KM 10 Aug '16

10 Aug '16

Hi All,I have a general question. I have an old rc type startup script that I am still using on CentOS 7. I got it to run by creating the systemd service file... a simple one as shown below, for Myservices. # used to set up the Myservices onstartup[Unit]Description=Start and stop Myservices[Service]Type=oneshotExecStart=/etc/init.d/Myservices startExecStop=/etc/init.d/Myservices stopRemainAfterExit=yes[Install]WantedBy=multi-user.targetThis works. When the server starts Myservices is initiated. However the boot keeps going. When I log in Myservices is still running. it takes about 5 minutes to complete. This is normal. What is different is the boot up used to wait for the service to finish and then continue. Can I use any options in my service file shown above, to make it wait before finishing the boot up? ThanksKM
