I Have Multiple Ips But Can Only Telnet to One Interface. Not the subinterface. How to Fix?
by Mike McKoy 21 May '15

21 May '15

Hi guys, I have multiple IPs bound to my Centos 6.6 box but I can only telnet to one IP. Any ideas on what to do? I've searched the internet so far with every keyword I can think of to no avail. I can see that postfix is only listening on the first IP and to localhost. The IP I cannot smtp to is on ETH0:1. I can access it via port 80 (web traffic) but the connection is refused if i try to telnet. [image: :shock:] The domain I can telenet to is mymodeltalk.com The domain I cannot telenet to is inform.mymodeltalk.com I have posted my current IP Tables rules, netstat, ifconfig -a, and route -n. I have SElinux set to permissive. [root@mail1 log]# netstat -plnt |grep :25 tcp 0 0 172.30.1.113:25 0.0.0.0:* LISTEN 18800/master tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 18800/master [root@mail1 log]# iptables -S -P INPUT ACCEPT -P FORWARD ACCEPT -P OUTPUT ACCEPT -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT -A INPUT -p tcp -m tcp --dport 587 -j ACCEPT -A INPUT -p tcp -m tcp --dport 110 -j ACCEPT -A INPUT -p tcp -m tcp --dport 143 -j ACCEPT -A INPUT -p tcp -m tcp --dport 993 -j ACCEPT -A INPUT -p tcp -m tcp --dport 995 -j ACCEPT -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT -p tcp -m tcp --dport 25 -j ACCEPT -A OUTPUT -p tcp -m tcp --dport 25 -j ACCEPT -A OUTPUT -p tcp -m tcp --dport 80 -j ACCEPT -A OUTPUT -p tcp -m tcp --dport 587 -j ACCEPT -A OUTPUT -p tcp -m tcp --dport 9292 -j ACCEPT -A OUTPUT -p tcp -m tcp --dport 110 -j ACCEPT -A OUTPUT -p tcp -m tcp --dport 143 -j ACCEPT -A OUTPUT -p tcp -m tcp --dport 22 -j ACCEPT -A OUTPUT -p tcp -m tcp --dport 25 -j ACCEPT [root@mail1 log]# ifconfig -a eth0 Link encap:Ethernet HWaddr 0A:28:21:76:97:85 inet addr:172.30.1.113 Bcast:172.30.1.255 Mask:255.255.255.0 inet6 addr: fe80::828:21ff:fe76:9785/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:9001 Metric:1 RX packets:793739006 errors:0 dropped:0 overruns:0 frame:0 TX packets:480841833 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:937438761212 (873.0 GiB) TX bytes:136066252190 (126.7 GiB) Interrupt:18 eth0:1 Link encap:Ethernet HWaddr 0A:28:21:76:97:85 inet addr:172.30.1.65 Bcast:172.30.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:9001 Metric:1 Interrupt:18 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:369804 errors:0 dropped:0 overruns:0 frame:0 TX packets:369804 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:207298477 (197.6 MiB) TX bytes:207298477 (197.6 MiB) [root@mail1 log]# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.30.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1002 0 0 eth0 0.0.0.0 172.30.1.1 0.0.0.0 UG 0 0 0 eth0 -- Mike McKoy *404.590.7176* http://MyForeverHair.com http://www.MyModelTalk.com http://InCrowdUSA.net http://www.google.com/profiles/mikemckoy

Turning off wifi in CentOS 7
by m.roth＠5-cent.us 20 May '15

20 May '15

Someone else got the 7 pxe install going, and one thing that's annoying is that NetworkMangler appears to be regularly trying to fire up the wifi. On a workstation, in a wired environment. I just want to tell NM to knock it off....It's Monday, and my searching isn't going too well. Clues for the poor? mark

Upgrading to CentOS 7
by Timothy Murphy 19 May '15

19 May '15

I read in <http://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool> "Warning: use of this tool is currently not recommended as several system- critical packages are of a higher version number in CentOS 6.6 than they are in CentOS 7 so those do not get upgraded correctly. This renders yum and several other system tools non-functional." Does this still hold? It seems to me a bit pointless to offer a tool with the warning that it does not work. -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

With 6.x and 7, "mail" is symlinked to mailx, which doesn't seem to have the "--" flag and the ability to pass the sendmail options. In both mail and mailx, a bare "-f" is a read from file.

Hi Guys, I'm facing this issue: https://bugs.centos.org/view.php?id=8482 It came after upgrading to 7.1 and only Firefox is affected, Chrome is working. What I've tried so far: - Tried NVIDIA drivers 340.65, 346.59 and 346.72 - Upgraded Firefox to 38 - Tried Safe more / Refresh Firefox - Tried to turn HW accel. off in Firefox None of these has helped to eliminate the issue. Do you know how to work this around? Many thanks, László

Missing Java packages for java-1.6.0-openjdk under CentOS 5
by Robert Heller 18 May '15

18 May '15

When I compile some Java code I am getting this sort of error: "package org.apache.http.annotation does not exist" I am presuming that I am missing a Jar file in /usr/lib/jvm/java-1.6.0-openjdk.x86_64. Most of the Jar files in /usr/lib/jvm/java-1.6.0-openjdk.x86_64 come from one or another RPMs, most from the CentOS 5 distro RPMs. But I cannot figure out which RPM(s) I am missing. I tried doing a web search for org.apache.http.annotation with el5 and rpm, but got nothing useful. What am I missing? -- Robert Heller -- 978-544-6933 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services heller(a)deepsoft.com -- Webhosting Services
