Fwd: Cross Building Tcl using Mingw32-gcc (4.9.2)
by Robert Heller 28 Apr '15

28 Apr '15

I posted this to the comp.lang.tcl newsgroup, but it might relate to a possible bug in the Mingw32 cross-build environment under CentOS 6 (or EPEL). Forwarded Message: From: Robert Heller <heller(a)deepsoft.com> Subject: Cross Building Tcl using Mingw32-gcc (4.9.2) Newsgroups: comp.lang.tcl Message-ID: <Nc-dnd1wRNTsy6PInZ2dnUU7-b-dnZ2d(a)giganews.com> Date: Mon, 27 Apr 2015 10:32:01 -0500 I am trying to cross-build Tcl (8.5.8) and I have encounted two problems: One I easily hacked the sources (wrapped the offending lines with #ifdefs): ./../generic/tclPosixStr.c:347:5: error: duplicate case value case EPFNOSUPPORT: return "EPFNOSUPPORT"; ^ ./../generic/tclPosixStr.c:290:5: error: previously used here case ENOPROTOOPT: return "ENOPROTOOPT"; ^ ./../generic/tclPosixStr.c: In function 'Tcl_ErrnoMsg': ./../generic/tclPosixStr.c:795:5: error: duplicate case value case EPFNOSUPPORT: return "protocol family not supported"; ^ ./../generic/tclPosixStr.c:738:5: error: previously used here case ENOPROTOOPT: return "bad protocol option"; ^ The other I am not sure how to fix: i686-w64-mingw32-gcc -c -O2 -fomit-frame-pointer -Wall -I"../../generic" -DTCL_TOMMATH -DMP_PREC=4 -I"../../libtommath" -I".." -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" -DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DSTDC_HEADERS=1 -DHAVE_NO_SEH=1 -DHAVE_NO_LPFN_DECLS=1 -DHAVE_ALLOCA_GCC_INLINE=1 -DHAVE_CAST_TO_UNION=1 -DTCL_CFGVAL_ENCODING=\"cp1252\" -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DTCL_CFG_OPTIMIZED=1 -DTCL_CFG_DEBUG=1 -DBUILD_tcl "../tclWin32Dll.c" -o tclWin32Dll.o ./tclWin32Dll.c:65:3: error: conflicting types for 'EXCEPTION_REGISTRATION' } EXCEPTION_REGISTRATION; ^ In file included from /usr/i686-w64-mingw32/sys-root/mingw/include/minwindef.h:146:0, from /usr/i686-w64-mingw32/sys-root/mingw/include/windef.h:8, from /usr/i686-w64-mingw32/sys-root/mingw/include/windows.h:69, from ../tclWinPort.h:72, from ../../generic/tclPort.h:25, from ../../generic/tclInt.h:3946, from ../tclWinInt.h:17, from ../tclWin32Dll.c:16: /usr/i686-w64-mingw32/sys-root/mingw/include/winnt.h:3554:43: note: previous declaration of 'EXCEPTION_REGISTRATION' was here typedef EXCEPTION_REGISTRATION_RECORD EXCEPTION_REGISTRATION; ^ Is there a solution possible?

Real sh? Or other efficient shell for non-interactive scripts
by E.B. 28 Apr '15

28 Apr '15

I'm sure most people here know about Dash in Debian. Have there been discussions about providing a more efficient shell in Centos for use with heavily invoked non-interactive scripts? With sh being a link to bash in Centos I don't know if it would explode if the link was changed to something else, but at least the scripts we made on our own that run certain services could be changed and tested manually to another shell. Are there other people who have experience in this and can provide interesting guidance?

Boot message of a modprobe.d conf file that does not exist
by Tim 28 Apr '15

28 Apr '15

Hi all, I got a message at boot: dracut-pre-udev: libkmod: kmod_config_parse: /etc/modprobe.d/thinkpad_battery.conf line 2: ignoring bad line starting with 'options' I have had this file to load modules for my thinkpad (acpi_call & tp_smapi) but I removed it after recompiling the modules for a new kernel and using "make install load". My question is, why this nonexistent file is still demanded. Thanks in advance Tim

CentOS 6.6 x86_64, rpm error: rpmdbNextIterator: skipping h# ...
by carlh04426＠gmail.com 28 Apr '15

Hi All, I had some health issues for a few months and I barely recall dealing with Heartbleed ... it's all just a blur. Now I'm getting back up to speed, but I have a pair of CentOS 6.6 x86_64 + Virtualmin 4.13 GPL servers which no longer seem to be picking up available updates. 'yum check' ran for about 25 minutes this evening on one of them and returned nothing useful. rpm -qa --last is returning this (lines intentionally split): error: rpmdbNextIterator: skipping h# 259 Header V3 RSA/SHA256 \ Signature, key ID c105b9de: BAD error: rpmdbNextIterator: skipping h# 4 Header V3 RSA/SHA256 \ Signature, key ID c105b9de: BAD error: rpmdbNextIterator: skipping h# 1028 Header V3 RSA/SHA1 \ Signature, key ID c105b9de: BAD - - - - 8< snipped for brevity, continuing to end - - - - ->8 - - - - error: rpmdbNextIterator: skipping h# 1019 Header V3 RSA/SHA1 \ Signature, key ID c105b9de: BAD gpg-pubkey-fe837f6f-4e0fd77e Thu 17 Jul 2014 12:00:11 AM EDT gpg-pubkey-ef1d6db8-4e0fd7f0 Thu 17 Jul 2014 12:00:11 AM EDT gpg-pubkey-d0ff3d16-4e0fd442 Thu 17 Jul 2014 12:00:11 AM EDT gpg-pubkey-a0bdbcf9-42d1d837 Thu 17 Jul 2014 12:00:11 AM EDT gpg-pubkey-11f63c51-3c7dc11d Thu 17 Jul 2014 12:00:11 AM EDT gpg-pubkey-c105b9de-4e0fd3a3 Tue 15 Jul 2014 02:32:15 AM EDT gpg-pubkey-0608b895-4bd22942 Mon 14 Jul 2014 07:59:25 PM EDT gpg-pubkey-6b8d79e6-3f49313d Mon 14 Jul 2014 07:57:56 PM EDT I'd be extremely grateful for any guidance or ideas you may wish to share.

Route traffic through private IP for only certain hosts
by Ian 28 Apr '15

28 Apr '15

Hi I am having a weird problem which I cant figure out - so I was hoping someone here could give me a hand. First off the end goal is that a specific server in my network runs an IPSEC connection to another company and I want all other servers to route traffic for the IP on that network through this single server. Server 1 in this example is the server that runs the IPSEC connection. (CentOS 6.6) Server 2 in this example is an app server that would route traffic for only that specific IP through server 1. (CentOS 6.5) **Some IP's that will be used below:** Server 1 <pre> Server 1 Public IP: x.x.x.x Server 1 Public Broadcast: x.x.x.y Server 1 Public Gateway: x.x.x.z Server 1 Internal IP: 10.0.64.10/24 </pre> Server 2 <pre> Server 2 Public IP: y.y.y.y Server 2 Public Broadcast: y.y.y.z Server 2 Public Gateway: y.y.y.a Server 2 Internal IP: 10.0.64.150/24 </pre> Those servers have full connectivity between them internally (i.e. I can ping, ssh etc from one to the other without problem). They also both have full acceess to the internet and can be reached that way ---------- **Server 1** Here is an *ip a* for that <pre># ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:99:12:85 brd ff:ff:ff:ff:ff:ff inet x.x.x.x/28 brd x.x.x.y scope global eth0 inet6 xxxx:xxxx:xxxx:xxxx/64 scope link valid_lft forever preferred_lft forever 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:99:12:8f brd ff:ff:ff:ff:ff:ff inet 10.0.64.10/24 brd 10.0.64.255 scope global eth1 inet6 fe80::20c:29ff:fe99:128f/64 scope link valid_lft forever preferred_lft forever </pre> Here is an *ip route* <pre># ip route x.x.x.y/28 dev eth0 proto kernel scope link src x.x.x.x 10.0.64.0/24 dev eth1 proto kernel scope link src 10.0.64.10 169.254.0.0/16 dev eth0 scope link metric 1002 169.254.0.0/16 dev eth1 scope link metric 1003 default via x.x.x.z dev eth0 </pre> Here is a *sysctl -p* <pre> # sysctl -p net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 68719476736 kernel.shmall = 4294967296 net.ipv4.ip_forward = 1 net.ipv6.conf.all.forwarding = 1 net.ipv4.conf.default.proxy_arp = 1 net.ipv4.conf.all.rp_filter = 1 kernel.sysrq = 1 net.ipv4.conf.default.send_redirects = 1 net.ipv4.conf.all.send_redirects = 1 </pre> ---------- **Server 2** I've added a single test ip (8.8.8.8) to server two to test if it works before bringing IPSEC into the equation Here is an *ip a* <pre> # ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 link/ether 00:0c:29:15:8b:01 brd ff:ff:ff:ff:ff:ff inet y.y.y.y/29 brd y.y.y.z scope global eth0 inet6 fe80::20c:29ff:fe15:8b01/64 scope link valid_lft forever preferred_lft forever 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 link/ether 00:0c:29:15:8b:0b brd ff:ff:ff:ff:ff:ff inet 10.0.64.150/24 brd 10.0.64.255 scope global eth1 inet6 fe80::20c:29ff:fe15:8b0b/64 scope link valid_lft forever preferred_lft forever </pre> Here is an *ip route* <pre> # ip route 8.8.8.8 via 10.0.64.10 dev eth1 y.y.y.z/29 dev eth0 proto kernel scope link src y.y.y.y 10.0.64.0/24 dev eth1 proto kernel scope link src 10.0.64.150 default via y.y.y.a dev eth0 </pre> ---------- Now when I try do a ping from Server 2 -> 8.8.8.8 here are the tcpdumps from each server: **Server 2** If I tcpdump on eth0 i get no matches (so the route appears right!). eth1 gets matches: <pre> # tcpdump -vvv -i eth1 -n host 8.8.8.8 tcpdump: listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes 11:25:55.609902 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.0.64.150 > 8.8.8.8: ICMP echo request, id 17999, seq 1, length 64 11:25:56.609262 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.0.64.150 > 8.8.8.8: ICMP echo request, id 17999, seq 2, length 64 </pre> **Server 1 (The hopeful gateway for 8.8.8.8)** On eth1 (Private) <pre> # tcpdump -vv -i eth1 -n host 8.8.8.8 tcpdump: listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes 11:27:20.608766 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.0.64.150 > 8.8.8.8: ICMP echo request, id 17999, seq 86, length 64 11:27:21.608738 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.0.64.150 > 8.8.8.8: ICMP echo request, id 17999, seq 87, length 64 </pre> On eth0 (public) <pre> # tcpdump -vv -i eth0 -n host 8.8.8.8 tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 11:29:04.608773 IP (tos 0x0, ttl 63, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.0.64.150 > 8.8.8.8: ICMP echo request, id 17999, seq 190, length 64 11:29:05.608800 IP (tos 0x0, ttl 63, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.0.64.150 > 8.8.8.8: ICMP echo request, id 17999, seq 191, length 64 </pre> I've disabled the FW on both (as a test), made sure to not have any blocking rules on FORWARD traffic (as a separate test) and I just never get my traffic through from Server 2 to 8.8.8.8. I've also tried substituting 8.8.8.8 for another server that is reachable from both servers and the same thing happens. I'm open to any suggestions - i'm super confused :) Thanks in advance, Ian

CentOS 7.1 How to change panel background
by Globe Trotter 27 Apr '15

27 Apr '15

Hi, I just installed CentOS and have been trying to change the desktop panel background (in gnome classic) to black. How do I do this? Holding the alt button while right-clicking on the mouse does not seem to do anything. I do not have anything installed (other than what came with the LiveCD). Many thanks!

CentOS 7 /boot location
by Devin Reade 27 Apr '15

27 Apr '15

I noticed that (in a case with a two disk md mirror and lvm), the CentOS 7 installer is now placing /boot as the *last* partition on the disk. I'm assuming that others are seeing this behavior. Does anyone know why it's now the last instead of the first? (Seems to work, though.) Devin

can't install gd-devel on centos 7.1
by Tim Dunphy 27 Apr '15

27 Apr '15

Hey guys, I'm trying to instal gd-devel onto a CentOS 7 host. --> Finished Dependency Resolution Error: Package: gd-last-devel-2.1.1-2.el7.remi.x86_64 (remi) Requires: libvpx-devel(x86-64) You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest But when I try to do that I get the error you see above. These are the repos I have installed and enabled: repo id repo name status epel/x86_64 Extra Packages for Enterprise 7,718 puppetlabs-deps/x86_64 Puppet Labs Dependencies El 7 17 puppetlabs-products/x86_64 Puppet Labs Products El 7 - x 162 remi Les RPM de remi pour Enterpri 1,928 rhui-REGION-client-config-server-7/x86_64 Red Hat Update Infrastructure 4 rhui-REGION-rhel-server-releases/7Server/x86_64 Red Hat Enterprise Linux Serv 6,851 rhui-REGION-rhel-server-rh-common/7Server/x86_64 Red Hat Enterprise Linux Serv 131 rpmforge RHEL 7Server - RPMforge.net - 245 webtatic/x86_64 Webtatic Repository EL7 - x86 519 I originally had nothing more than the base CentOS repo enabled. Along with the puppetlabs repo and epel when I first encountered this error. But then I tried adding some repos to find out if I could find the needed package in any of them. The package that it seems to be complaining about not having is called: libvpx-devel(x86-64) But when I try to instal that this is the result I get: [root@monitor1:~] #yum install libvpx-devel Loaded plugins: amazon-id, rhui-lb No package libvpx-devel available. Error: Nothing to do Does anybody have any ideas on how I can get around this problem? I only want to install gd-devel. Seems like it should be so simple! But not in this case. :( Thanks!!
