[CentOS] upgrading from CentOS 7 to 8
I searched a bit to see if there is a way to upgrade from CentOS 7 directly to CentOS 8. I found RHEL instructions but not CentOS. Although they probably should be/would be similar, the instructions I found enable a rhel repository to get the leap command, which I can't seem to do in CentOS. Does anyone know if you can do an upgrade yet. I know they had been working on it in the past. also - when they say upgrade (for example on the rhel pages), is it in place meaning I can leave my files/data there, or is it strictly a way of installing the OS that is going to wipe out my files? Thanks in advance. KM ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] [Solved]:Re: netmask set with ifconfig doesn't hold
BTW - that seemed to work, thanks. putting /18 changed the netmask as i wanted. I see that the PREFIX value in the corresponding ifcfg- file changes accordingly also. thanks againK On Thursday, March 14, 2019, 11:58:57 AM EDT, Pete Biggs wrote: On Thu, 2019-03-14 at 15:42 +, KM via CentOS wrote: > I should have mentioned that I tried nmtui but found no settings for > a netmask anywhere. like I said …. dummy. It's part of the IP address - so you put something like 192.168.0.1/24 for a 255.255.255.0 subnet. It's called a CIDR address.

I should have mentioned that I tried nmtui but found no settings for a netmask anywhere. like I said …. dummy.KM On Thursday, March 14, 2019, 11:39:09 AM EDT, Pete Biggs wrote: On Thu, 2019-03-14 at 15:12 +, KM via CentOS wrote: > I gather that ifconfig is a way of setting the netmask in the current > shell instead of a persistent value.

CentOS 6 & 7 use network manager to control the interfaces. Probably the easiest way to edit a connection for inexperienced users from the command line is 'nmtui'. You can also use 'nmcli' from the command line, but you have to craft the command yourself and it can get quite involved if you don't know what you are doing. You may need to restart the network to pick up the new config after editing it.

[CentOS] netmask set with ifconfig doesn't hold
I gather that ifconfig is a way of setting the netmask in the current shell instead of a persistent value. I say this because I am running it and see it for my specific network interface, directly after running it. However if I restart the network service the netmask is reverted to the previous value. What is the correct way to set the new netmask for the network interface to make it persistent. if it's different for CentOS 6 and 7 I'd like to know that too. FYI - I tried searching about this but none of the info has really helped so far. Also consider this like "changing netmask for dummies" since I am not an administrator and am just searching and trying these things. Thanks very much in advance.KM ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] CentOS 7 bash perhaps off topic
So you are saying that the actual "while read line do ….. done …." is what is failing?Try sending the output of the smwebsocket "$URL" | grep Location so we may see what is being passed to the while read line. Additionally you could use sh -x to execute it and it may show something. You could send the code exactly also.K On Monday, November 26, 2018 03:11:14 PM EST, Jerry Geis wrote: hi all, I have a small script that seems to be exiting and hitting the sleep 60... The smwebsocket just connects to the web socket provided and outputs the data. This works manually. the myprogram just opens a database and writes the line... My desire is to run the smwebsocket, connect to the websocket and output the data (line by line) when we get a line that matches Location take that line and output to the database. Seems simple. I desire this to keep the connection alive and just continue to read data and grep on the data etc... if smwebsocket does exit, sleep 60 and reconnect. However it seems to be exiting and running the sleep 60. Am I missing something ? while [ 1 ] do smwebsocket "$URL" | grep Location | while read line do myprogram -data "$line" done sleep 60 Reconnecting... done All the pieces work - just not the actual running. What am I missing?

[CentOS] Using InstallAnywhere with CentOS? ... anyone
Hi All,I was wondering if anyone else uses InstallAnywhere to create a multi-platform installer for their products. My company does. However we have an official build server that is running CentOS, obviously because it is opensource and easy to update etc. However after we converted our build from an old RedHat 5 server to CentOS and were using InstallAnywhere we found out that it is not officially supported on CentOS but is officially supported on RedHat. This doesn't really make any sense to me since they are the same (or virtually the same). I guess it has to do with the amount of time a company wants to spend testing products on different platforms. All this being said, the main reason for this email is to encourage anyone using InstallAnywhere on CentOS for the designer and build functionality, to request that Flexera support CentOS officially. I only want this in case we have specific issues that arise due to the platform. Although it is true the RedHat users will most likely see the same results, it would be beneficial to have official support. Note that CentOS is support as a runtime or production execution platform. I am speaking mainly of the build and design functionality. Please also note that Flexera has not refused to help me with any of my issues so far. They have been great, but these issues are not OS related, they had to do with the use of their product. Thanks in advance for any help that you may give.KM ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
