Это руководство пояснит как настроить сетевое подключение, изменить IP-адрес или добавить новую сетевую карту в системе CentOS 6.

This nifty tool will print the status of each NetworkManager managed interface, as well as the connection state:. When I was looking into this issue, I learned about the nm-tool utility. As I mentioned in a previous post, I spent some time trying to get the NetworkManager to respect my custom DNS settings.

Org into my hosts file with the IP I got from ping so I did get a yum update, but the yum update still didn’t fix the problem. For example, with my own LAN nameserver, I can ping ibiblio. 4, both minimal and full DVD installation of “Web server”, with the same failure experiences on this one DNS point, I am very appreciative of your help and wish to potentially save many others hours as well. Nor was it fixed by a yum update , as I just put mirror. To reiterate, ping works OK with various resolv. 3 and CentOS 6. It still leaves the issue of “WHY. Org then ftp fails (” No address associated with hostname”), but I can ping again successfully. Org but if I immediately thereafter try to ftp ibiblio. Of course, the other nameservers work with all other devices of my office and my home. Conf This came AFTER I unsuccessfully tried my own router’s nameserver at 192. Conf , which worked. 4 installation that I tried I put Google’s public nameserver as the *first* line of resolv. It’s only on my latest 6. 8 server for some reason and another CentOS server installation many months ago. 1 and my local ISP’s nameserver and one of my own server’s nameserver. Just try different nameservers until you find one which works for your CentOS, or use Google’s. Regarding another user’s solution by working on named, I do not have named installed and I suspects others do not, either. As I have spent hours on this problem, with multiple reinstalls of CentOS 6. What worked for me is just using the Google public nameserver in your example, the 8. However, if Google’s public nameserver was the second line then it failed. 8 nameserver as the first line. It’s actually your mention of the Google public nameservers which were the solution which worked for me. The other nameservers *do* work with my old CentOS 5. It wasn’t fixed between CentOS 6. Conf settings but yum and ftp did not work on hostname lookups with the same settings. 8 as the first line in resolv. Since many people have reported having the same problem, surely countless other people are having it as well. Which is very strange to me that only Google’s public nameserver works for me. 4 which I just installed this week. I have experimented a bit, and the only thing which works well for me is Google’s 8. Installing named and properly configuring it is apparently unnecessary to solve this problem.

Two useful options are the ability to specify the DNS servers and search domains in the network-scripts files, and have those applied when a DHCP lease is acquired (this assumes you override the values provided by your DHCP server). I recently switched my work Desktop from Ubuntu to Fedora 11, and noticed that there are some new configuration options now that network intefaces are managed by the NetworkManager process. To override the DNS servers and search domains, you can set the DNS1, DNS2 and DOMAIN variables in your favorite ifcfg-eth[0-9]+ script:.

Red Hat Enterprise Linux 6, place all interface-specific bonding options after the
 . For example, the ifcfg-eth0 file for an interface using DHCP looks different.

On CentOS I no longer have a ifcfg-eth0 configuration file (I deleted it). When I run system-configure-network it shows no interfaces that I can edit.

To create a network bridge, create a file in the /etc/sysconfig/network-scripts/ directory called ifcfg-brN , replacing N with the number for the interface, such as 0.

Updated with a couple more lines of shell script (you could cross reference the package list above with /root/install. Log if you need to get super specific). Now this doesn’t take into account package updates, but it should be pretty easy to identify which items were added vs.

How do I setup a static TCP/IP address on my CentOS Linux 7 or Red Hat. Create a file named /etc/sysconfig/network-scripts/ifcfg-eth0 as .

Vi /etc/sysconfig/network-scripts/ifcfg-eth0; Modify the file to  . Open the configuration file for the first network interface, eth0, into a text editor. Set a DHCP Address.

There is no file in /etc/sysconfig/network-scripts/ifcfg-eth0 there is only a. NetworkManager 0:off 1:off 2:on 3:on 4:on 5:on 6:off network 0:off 1:off .

Make the change persistent by adding the line below to the file /. Set up Wake On LAN (WOL) on CentOS 7. ETHTOOL_OPTS=”-s ${DEVICE} wol g”. Setting up Wake on LAN on a CentOS 7 server.

    The problem of awkward filenames is so bad that there are programs like detox and Glindra that try to fix “bad” filenames. But the real problem is that bad filenames were allowed in the first place and aren’t prevented or escaped by the system — cleaning them up later is a second-best approach. The POSIX standard includes pathchk; this lets you determine that a filename is bad.

    In other words, the lack of a standard creates arbitrary and unreasonable limitations. That’s ridiculous; most computer users don’t even know English. If we did agree that UTF-8 encoding is used, the set of portable characters could include all languages. Note that this is a very restrictive list; few international speakers would accept this limited list, since it would mean they must only use English filenames. So why is this standard so restrictive. Its “Portable Filename Character Set” (defined in 3. That’s because there’s no standard encoding; since you don’t know if a filename is UTF-8 or something else, there’s no way to portably share filenames with non-English characters. 276) is only A-Z, a-z, 0-9, , , and . Again, let’s look at the POSIX.

    Similarly, a leading dash is ASCII 0x2D becomes Unicode U+DC2D, encoding to UTF-8 0xED 0xB0 0xAD. Thus, newline n (0x0A, aka U+000A) would become Unicode “character” U+DC0A, encoding to UTF-8 0xED 0xB0 0x8A. ” or some such. A different approach would be to use an approach similar to Python PEP 383 encoding (though encoding non-slash bad bytes 1-127 as well). Bad filenames would get a little longer (each bad byte becomes 3 bytes), but there shouldn’t be many bad filenames in the first place, and many bad filenames only have a few bad bytes (unless they are due to encoding mismatch). The advantage of this approach is that PEP 383 encoding doesn’t interfere with good filenames at all; it only renames bad filenames. These might display in an ugly way, but that is often true even without encoding, and display systems could be taught to display these with “. When the kernel gets a filename from userspace that includes UTF-8-encoded U+DCxx characters, they would be encoded back (except for encodings of and “/”, which would be ignored). If the filename stored on disk already has UTF-8 encoding of U+DCxx, it would be encoded again (so that when it is decoded later we end up with the original filename). Such filenames are likely to be considered legal UTF-8, and thus programs that expect UTF-8 will like these filenames. The largest possible bad byte is 0xFF, becoming Unicode U+DCFF, encoding to UTF-8 0xED 0xB3 0xBF. In short, encode each bad byte (other than ASCII NUL and slash) to U+DCxx (the low-surrogate code points), then encode that with UTF-8. Enabling this in some sense requires that filenames normally be UTF-8 (ASCII is a valid subset of UTF-8), since many other encodings would permit 0xED as a valid character, but it would work as an intermediate stage; if a filename uses a different encoding, it can still be found and then renamed to UTF-8. This would include encoding bytes that are not valid UTF-8 in the underlying filesystem.
