[CentOS] Roundcubemail

[TE Dukes]

Hello,

Just upgraded from CentOS 7 to CentOS 8 Stream and there is no rpm for
roundcubemail.

Could I get the SRPM for CentOS 7 and re-do it for CentOS 8? I really hate
installing a non-RPM package.

If not a good idea, what is available for webmail in CentOS 8 Stream?

TIA

[CentOS] OT:: Multiple PHP versions

[TE Dukes]

Hello,

Been trying to get multiple versions of PHP on a CentOS 7 machine, off and
on for the past couple months. I have followed 5 or 6 different howtos but
none work. They are very similar and they seems to be done on a fresh
install as most do an apache install is the steps. I setup two virtualhosts
one for PHP5.6 and one for PHP 7.4. When I create a file with phpinfo, it
reports back 5.6.xxx on both sites.

So, I'm wondering if I need to remove the existing PHP version that is
included with CentOS? Any suggestions or a better way to do this?

TIA

[CentOS] OT Help: Zoneminder

[TE Dukes]

Sorry for the off topic post but I have run out of options an hoping someone
here can help.

I have been running Zoneminder for a very long time. Its had its bumps in
the road as anything else but generally works well.

Currently running Zoneminder 1.36.8 on CentOS 7 .

The problem started back in June after an upgrade. When events are played
back, the first one plays fine, then it's a blur as in the faster than light
drive kicks in. Supposedly, there is supposed to be some kind of pause
between event playback that keeps this from happening.

I posted this issue on their forum,
https://forums.zoneminder.com/viewtopic.php?f=43&t=30955&p=122258#p122258
and on their Github, https://github.com/ZoneMinder/zoneminder/issues/3359
but have had no replies. There is a similar issue on github back in 2015,
but the file in question has been changed since that time.

I have thought about uninstalling and re-installing the version that was
working prior to the upgrade but I don't think its Zoneminder. I think it
could be something else causing the problem.

The problem occurs when playing back events using Firefox and Edge on a
Win10 PC and it does the same playing back events with Firefox on the server
itself.

TIA

My bad, rpm -V glibc returns nothing.

rpm -V returns nothing.

Re: [CentOS] Mail has quit working

Added back the IPV6 to /etc/hosts a couple days ago for grins and giggles.
No longer getting IPV6 errors in logwatch for bind. Everything working.

I think removing my ISP's nameservers from /etc/resolv.conf was the fix.
They have been in there forever so still have my fingers crossed.

Again, many thanks!!

The mail in question is system mail sent via cron. I access it from both
inside the network and outside. Due to being on a dynamic ip, I can't send
mail to the outside but I can receive it.

Again, really appreciate the help!!

Pretty sure SELinux is turned off unless it got turned on without my
knowledge through an updtate/upgrade.

I removed the TLS lines from main.cf I added last night and remotely did a
reboot from here at work.

Mail is again working!! I am skeptical to mark this thread solved as I
thought it was solved back in July.

I think, removing my ISP's DNS servers from resolve.conf was the fix, could
be removing IPV6 from etc/hosts. Might put it back in just to see.

Again, many, many thanks!!

I really want to thank everyone for their help and patience!!

Thanks again! I still think it's a mail issue. I can't get mail using
usermin either. 

Think I'm going to remove the TLS stuff from postfix main.cf that I added
yesterday and retry.

The first two nameservers belong to my ISP. Should I move 127.0.0.1 to the
top?

I have all the files shipped with CentOS. I created 2 zone files, domain and 
reverse from the example in RHEL Documentation 
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/networking_guide/sec-BIND#example-bind-zone-examples-basic
 

https://paste.fedoraproject.org/paste/9-ZvmUg5vF-UI7lfuAIJjQ

I did find one typo in the domain zone but correcting that didn't help

Getent hosts localhost and getent hosts 127.0.0.1 returned no info.

Thanks. I did open the port but made no difference.

I found this in the roundcube mail error file:

[26-Aug-2018 11:48:41 -0400]:  IMAP Error: Login failed for tdukes
from 192.168.1.102. Could not connect to localhost:143:

/usr/share/roundcubemail/program/lib/Roundcube/rcube_imap.php on line 197
(POST /?_task=login?_task=login&_action=login)

There is also a warning about the time zone. It's set as America/New_York in
php.ini

My ip has changed since I ran telnet localhost 25 as I rebooted my router.
But it is correctly reporting the IP.

#
# /etc/nsswitch.conf
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Valid entries include:
#
#   nisplus Use NIS+ (NIS version 3)
#   nis Use NIS (NIS version 2), also called YP
#   dns Use DNS (Domain Name Service)
#   files   Use the local files
#   db  Use the local database (.db) files
#   compat  Use NIS on compat mode
#   hesiod  Use Hesiod for user lookups
#   [NOTFOUND=return]   Stop searching if not found so far
#

# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd:db files nisplus nis
#shadow:db files nisplus nis
#group: db files nisplus nis

passwd: files sss
shadow: files sss
group:  files sss
#initgroups: files

#hosts: db files nisplus nis dns
hosts:  dns files myhostname

# Example - obey only what nisplus tells us...
#services:   nisplus [NOTFOUND=return] files
#networks:   nisplus [NOTFOUND=return] files
#protocols:  nisplus [NOTFOUND=return] files
#rpc:nisplus [NOTFOUND=return] files
#ethers: nisplus [NOTFOUND=return] files
#netmasks:   nisplus [NOTFOUND=return] files

Thanks,

I have removed DNS3 from ifcfg-eno1 and set ONBOOT=no in ifcfg-enp1so0, reboot 
and still can't read mail. Logging into roundcube either times out or if I get 
in, the inbox is empty.

I caught it after I did it, that's the /etc/host.conf

/etc/host should be:

192.168.1.110   ts130.palmettodomains.com   ts130

Whsh, senior moment!!

Here's the link:
https://paste.fedoraproject.org/paste/MMNEJmqIrEzK-A4N3MR0ZA

I just recently disabled IPV6 due to errors resolving I saw in the logs.
This was AFTER mail quit working the second time. It did not correct the
problem. Both times, this has happened after a kernel upgrade. I have had no
errors this time, except for IPV6 stuff.

Gz!! Its working again. All I did was restart the system.

I stopped and restarted postfix, dovecot, mariadb several times over the
past couple days. Pretty sure I did a system reboot a time or two.

Decided to do one a few minutes ago and now its working. Hate I never found
the problem that caused this issue!

Thanks for all the help!!

In one terminal: "tail -f /var/log/maillog" or "journalctl -f"

In another, "echo test | mail -s test your@email.address"

What do you see in the maillog at that time?  What does the "df" command 
output?

Re: [CentOS] Mail has quit working

[TE Dukes]

OK, not sure what happened, my response was rejected by Centos:

Reason: There was an error while attempting to deliver your message with 
[Subject: "RE: [CentOS] Mail has quit working"] to centos@centos.org. MTA 
p3plwbeout03-06.prod.phx3.secureserver.net received this response from the 
destination host IP - 208.100.23.70 -  554 , 554 5.7.1 Service unavailable; 
Client host [72.167.218.218] blocked using ix.dnsbl.manitu.net; Your e-mail 
service was detected by mail.ixlab.de (NiX Spam) as spamming at Tue, 24 Jul

http://www.dnsbl.manitu.net/lookup.php?value=72.167.218.218

So, I'm trying a third time:

This is pointless because he's complaining about cron and system emails
which use the sendmail command are submitted through the pickup service,
not port 25/smtp (in fact, if you're submitting any mail via port 25
you're doing it wrong but that's another discussion).

TE Dukes:

Please do the following (lines that start with # should be run as root,
lines that start with $ should be run as a local user):

Install the mail command which is an easy interface to the sendmail
command and thus the pickup service.

# yum install mailx
# tail  -n0 -f /var/log/maillog

then in another window (replace someu...@example.com with your own
email address):

$ mail -s 'Test Email' someu...@example.com <<< "This is a test"

 wait a minute for postfix to have a chance to process and send the
message, then break out of the tail command and copy/paste the output
into your reply.

Then also copy and paste the output of the following:

$ postconf -nf; postconf -Mf

If I need any more info after that I'll let you know.

I can't get past From:   I also tried 'from', lower

[CentOS] Mail has quit working

[TE Dukes]

Hello,

Mail has come to an abrupt stop. Running C7, postfix and dovecot. Using
Roundcube as the client.

Mail stopped working Saturday and I cannot figure was has happened. I have
not touched this server except to upgrade packages. I believe Roundcube was
updated maybe a week ago but know I was getting mail since then.

Crond is no longer send mail. I checked /var/spool/mail as well as /Maildir
in home directories. Zero byte files.

Checked all logs and the only thing I could find was  in /var/log/maillog :
warning hostname localhost does not resolve to address 127.0.0.1

I corrected that by changing inet_interfaces to localhost from all in
postfix.cf

When I try to log in with Roundcube, it just times out.

I'm stuck!

TIA for any suggestions!!

Thanks!!

I'm only considering a SSD drive due to the lack of 3.5 drive space. I have
unused 5.25 bays but I'd have to get an adapter.

I probably don't need to go the RAID 10 route. I just need/would like some
kind of redundancy for backups. This is a home system but over the years due
to HD, mainboard, power supply failures, I have lost photos, etc, that can
never be replaced. Backing up gigabytes/terabytes of data to cloud storage
would be impractical due to bandwidth limitations.

Just looking for a solution better than what I have. A simple mirror is more
than I have now. I'd like to add another drive for redundancy and go from
there.

What should I do?

TIA

Let me add this which I failed to mention.

This was a fresh install as a "Server with Desktop". I have been adding
packages as needed.

Week before last when working on this, I was looking through the logs and
found REAR need syslinux which wasn't installed. I may not have all the
packages installed I need. I run REAR as a cron job around 2AM. If I did a
reboot/restart and forgot to manually mount the USB drive or forgot to click
on it gnom, which is usually the case, I don't get a backup.

It ran last night and I was OK, but I'd still need to find out why its not
mounting by itself.

Thanks

Thanks,

My first thought it might be a dns issue. I may change to googles dns
servers and see if things improve.

This just started in the last couple days. I know TWC and Charter are
merging, but this is irritating.

I'll check out wireshark.

Thanks for the info.

I've seen that site before so I might check it out.

My router/modem has a log. Its loaded with errors I can't interpret. I
googled a portion of it and landed on TWC forums. 

Missing BP Configuration Setting TLV

http://forums.timewarnercable.com/t5/Connectivity/Predictable-disconnects/td

Didn't see much of an answer.

Hopefully it's a temporary thing as it just started.  I don't think it's a
problem on my end, maybe, but doubt it. I'll give it another day or so.

[CentOS] Spotty internet connection

[TE Dukes]

How do you IT guys diagnose the problem with a spotty internet connection?

Just spent an hour on the phone with TWC/Spectrum. Of course they don't see
anything wrong with their service. 

They send me to speedtest.net. The first attempt, the page didn't fully
load, the second attempt, the page didn't load at all, the third attempt, it
loaded.

On a 20/2MB line I get 24.83/2.47MB. The speed is better than what I'm
paying for but its spotty.

Lately I have been getting slow  and partial page loads, server not found,
server timed out, etc.. Get knocked off ssh when accessing my home server
from work, etc. Its not the work connection because I don't have problems
accessing other sites, just here at home and my home server.

Is there any kind of utility to check for failing hardware?

TIA

/etc/php.ini

When I started getting the errors logging in, I checked the value. The value
hadn't changed.
The date on the file is going to be invalid since I 'messed' with it _AFTER_
getting the error as well as restarting httpd numerous times since then.

I restarted httpd  around 11:43 when I modified
/etc/httpd/conf.d/phpMyAdmin.conf so I could access phpmyadmin remotely and
renamed the alias for it.
When I got finished I changed at access portion back and restarted again.

Have been using mailscanner with postfix for years with no problems..

I do believe it does not work with 7.3.  It does not start postfix as it did
in 6.8 and earlier versions. There may be other problems besides that as
well. 

Figured out it wasn't a firewall issue when I would telnet to localhost 25
and got connection refused. As soon as I started postfix manually, I could
connect.

Mail works now that it has been uninstalled and adding a few things from
last night that were posted.

I have setup clamav and spamassassin using this guide.

http://www.tecmint.com/integrate-clamav-and-spamassassin-to-protect-postfix-
mails-from-viruses/

Seems to work.

[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone = America/New_York

Its set. Not sure why its not seeing it. The only changes I made to php.ini
was this last week when I installed 7.3 and zoneminder.

Its been working up till about noon today.

Put a simple php page on your/the server (where zoneminder is
running) with the "phpinfo()" function, and then look at the timezone
information in the "date" section of the output. 

If it isn't showing the correct value, check the location of the php.ini
that is being used in the "Loaded Configuration File" value toward the top
of that output.

By default, php doesn't use the system's TZ,


Hello,

I did, it shows the error about not being correctly set:

Warning: phpinfo(): It is not safe to rely on the system's timezone
settings. You are *required* to use the date.timezone setting or the
date_default_timezone_set() function. In case you used any of those methods
and you are still getting this warning, you most likely misspelled the
timezone identifier. We selected the timezone 'UTC' for now, but please set
date.timezone to select your timezone. in /var/www/html/phpinfo.php on line
4

Why would it just start doing this?

[CentOS] time zone

[TE Dukes]

Today, I started getting this error when trying to login to zoneminder:

 

ZoneMinder is not installed properly: php's date.timezone is not set to a
valid timezone

 

Zoneminder has been running since last Wednesday when I installed it. Today,
I get this.

 

In /etc/php.ini, I have date.timezone = America/New_York, which I added when
zoneminder was installed.

 

Output from date: Tue Jan 31 15:56:26 EST 2017

 

Output from ll /etc/localtime: lrwxrwxrwx. 1 root root 38 Jan 25 19:05
/etc/localtime -> ../usr/share/zoneinfo/America/New_York

 

Been searching for hours for another file that may be overriding php.ini

[CentOS] Question about 7.3

[TE Dukes]

I haven't done a fresh install in years. I've always gone the upgrade route.
Seemed to have always worked for me.

I moved to 7.3 since it supports the latest versions of some programs I want
to use to implement as a backup server/RAID/NAS for 3 machines here at home
and a remote laptop at work.

So, the question is, is there something different in 7.3 than the previous 7
versions?

The reason I ask is I was running a lesser version of 7, I think 7.1, as a
VM on 6.8. I remember I chose not to install the most recent version at the
time. Never had these issues. Not really issues but everything just worked
without a lot of expertise involved.

One thing I could never figure out is that on 6.8, I have the zoneminder
repo installed and when I did a yum update on the 7.1 VM, it was also
accessing the zmrepo which wasn't installed. Just thought it was odd.

Anyway, I really appreciate the help and keep paying it forward!!

[CentOS] Mail issues

[TE Dukes]

I know I'm wearing you guys out.

I thought I had mail working. It is but it isn't.

Mail is stuck in /var/spool/mail.

This is a fresh install of dovecot and postfix. I have uninstalled
mailscanner as well until I can figure out what's wrong.

I sent a test mail from root to tdukes but its not being delivered to
~/Maildir

Here's the clip from maillog:

Jan 30 18:40:42 ts130 postfix/pickup[4828]: 2DF2D82CA5B9: uid=0 from=

Jan 30 18:40:49 ts130 dovecot: imap(tdukes): Disconnected: Logged out in=82

Do I need to install additional packages that move mail to the user's
/Maildir?

Thank you!!

Its working now! Never had to do that before, everything always worked out of 
the box.

# Location for users' mailboxes. The default is empty, which means that Dovecot
# tries to find the mailboxes automatically. This won't work if the user
# doesn't yet have any mail, so you should explicitly tell Dovecot the full
# location.
#
# If you're using mbox, giving a path to the INBOX file (eg. /var/mail/%u)
# isn't enough. You'll also need to tell Dovecot where the other mailboxes are
# kept. This is called the "root mail directory", and it must be the first
# path given in the mail_location setting.
#
# There are a few special variables you can use, eg.:
#
#   %u - username
#   %n - user part in user@domain, same as %u if there's no domain
#   %d - domain part in user@domain, empty if there's no domain
#   %h - home directory
#
# See doc/wiki/Variables.txt for full list. Some examples:
#
#   mail_location = maildir:~/Maildir
#   mail_location = mbox:~/mail:INBOX=/var/mail/%u
#   mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n
#
# 
#
mail_location = maildir:~/Maildir  <-- this!!

Really appreciate the help!!

Re: [CentOS] firewalld

[TE Dukes]

Still un-resolved.  Could be wrong but I think its firewalld preventing me
from accessing mail with roundcube.

I'm getting Connection to storage server failed.
>From roundcubemail log:

There is absolutely nothing in the httpd logs.

connection refused.

[CentOS] Preferred mail client

[TE Dukes]

Hello, again,

What is the preferred remote mail client for 7.3?

I have used openwebmail in the past, was using usermin and roundcube most
recently. Never cared about squirrelmail but that was years ago.

I don't use my server as a workstation. It mostly just sits over there
collecting dust on the keyboard.

Hello,

Still don't have mail working. It seems to be stuck in

Just a side note here, since EL7 removed net-tools from the default install
(after all it has been deprecated for about a decade now) you probably
should get used to providing advice using the iproute2 suite instead.

In this case `ss -tlnp` to list all tcp ports in a listening state, showing
the pid using the port and not resolving the ports to friendly names.

For an example of why this is important think about using pacemaker or
keepalived to manage IPs migrating between systems. They won't be visible
using ifconfig but only via ip as they aren't exposed in the kernel
structures that ifconfig uses -
https://www.hogarthuk.com/?q=node/6

Another example is when you have multiple interfaces and you have source
policy routing (or similar advanced routing behaviour) that makes use of
rules and multiple routing tables. The older route command is only capable
of displaying the default main table, not the rest of the tables in use, but
`ip route show table all` will give you all the routing tables in use on
your system (even in a default install it's a lot more than the route
command shows) and ip rule gives you the rules in use, if any.

On a similar note bridge-utils is also deprecated, though brctl is ingrained
into many minds!

https://fedoramagazine.org/build-network-bridge-fedora/

Thanks for the info. I'll take a look at it.

Again, thanks!

firewalld isn't the only thing that will prevent services from accessing the
internet. I found that I needed to do a relabel before postfix could access
DNS and I have seen other issues as well. Have you tried disabling the
firewall to see if you can get connections to work? Then try to disable

# netstat --inet -l -n

Is the service listening on port 143?

# systemctl stop firewalld

Does it now work?

Once you establish what's biting you then you can fix it. To force a relabel
do

# touch /.autorelabel

# reboot

I have dovecot answering now. I can read mail using Mutt.

I think I have problems with mysql/mariadb using roundcube. It may be I need
to open ports for mariadb as well.

Thanks,

That's a better explanation of things than I have read so far.

Yes, initially I wasn't adding the --permanent to the rules but I wasn't doing 
really any reboots.

I did a few --reloads so that may have gotten me.

I have zoneminder, dns, and  urbackup  working. I can ssh and scp in from work 
but mail is being a pain.

 I'm telneting in from ssh on a machine on the local network, still getting
connection refused.

The zone apparently means something because an interface can only be on one.
Moving it to a different zone results in the same error (same services/ports
opened in each zone).

I may as well disable firewalld and let my router handle the firewall.

I don't plan to use my server as a workstation.

[CentOS] firewalld

[TE Dukes]

Got 7.3 installed Wednesday, things went so so.

Been working on getting roundcubemail setup and firewalld is kicking my
butt.

I can't figure out all these zones. I opened imap, imaps, pop3, pop3s, smtp,
smtps in zones internal, trusted and public.

I still get connection refused.

I telnet localhost 143, I get connection refused.

What zone is used for the local network and what zone is used for outside
access? Two days and can't access mail.

Is this a Redhat brain child? According to firewalld.org, only Redhat,
CentOS and Fedora are using it.

Not too happy

Thanks for the heads up and link.

I don't really do anything special with apache except for my test website
that use a .htaccess file to rewrite for seo urls.

I am more concerned with mail and dns. Fail2ban wasn't an easy setup getting
rules to work. Then there's iptables and ipset.

Hope I can hit the ground running.

Actually, I've been running a centos 7 vm for a couple months now on a 6.8 
system with no problems. Just been scared to do a fresh install because it 
can't be upgraded from 6.8.

I'm saving the old HD just in case I need to revert back.

This will be the first time in 20 yrs that I'll try 'custom' partitioning. I've 
always gone the default route. I want to setup extra space/partition for 
backups until I can build a stand alone NAS.

I hope all my config files in 6.8 work in 7.3.

I didn't have this info last night. The lady on the phone just read me a

[CentOS] [OT] VOIP

[TE Dukes]

Hello,

I changed ISPs a few weeks ago and now I'm on cable.  In doing so, I lost
the ability to use the DSL as a FAX line.

So, I bought an OOMA. Turns out it uses a number of ports, three of which
are reserved, 53 TCP/UDP, 110 TCP and 443 TCP. These ports have already been
port forwarded from my cable modem/router to my server.

I'm thinking this isn't going to work unless I change some ports on my
server, which I'm not willing to do.

I spent over 30 minutes with their support people last night. It appears the
ports cannot be changed on the OOMA device.

Are there any work arounds?

Thanks for the link. I was using an older version.

Still doesn't work.

Any way, I joined the backuppc list and asked for some help.

HI,

[CentOS] BackupPC

[TE Dukes]

Hello,

Been working on this for a couple days and I am stuck!

Followed the CentOS WIKI on BackupPC to the letter. It may be outdated, not
sure. I also looked at the tutorial on HowToForge.

I'm trying to get a windows client to backup via smb.

I created the user 'backuppc' on the windows client with admin priviledges.
I can map the drive/share from my CentOS Samba server using 'backuppc'
credentials.

Here's the error:

full backup started for directory /
Running: /usr/bin/ssh -q -x -l root hp8200 /usr/bin/rsync --server --sender
--numeric-ids --perms --owner --group -D --links --hard-links --times
--block-size=2048 --recursive --ignore-times . /
Xfer PIDs are now 27000
Read EOF: Connection reset by peer
Tried again: got 0 bytes
Done: 0 files, 0 bytes
Got fatal error during xfer (Unable to read 4 bytes)
Backup aborted (Unable to read 4 bytes)
Not saving this as a partial backup since it has fewer files than the prior
one (got 0 and 0 files versus 0)

/etc/BackupPC/hp8200.pl

$Conf{XferMethod} = 'smb';
$Conf{SmbShareUserName} = 'backuppc';
$Conf{SmbSharePasswd} = '';
$Conf{SmbShareName} = 'C';

Looking at the -l option it appears 'root' is trying to login. Windows
doesn't use a root account per se.

Do I need to change something in the config.pl?

TIA

I found that I had done a chattr -i /etc/resolv.conf  some time ago. Its now
corrected.

If you want to use NetworkManager, edit
/etc/NetworkManager/NetworkManager.conf and add "dns=none" in the main
section:

[main]
plugins=ifcfg-rh
dns=none

If you don't want to use NetworkManager, then set PEERDNS=no and remove any
DNS1, DNS2, etc settings in /etc/sysconfig/network-scripts/ifcfg-*

Thanks!

I made the change in ifcfg-eth0 and eth1 to PERRDNS=no.

Then I did a really dumb thing -- I did a service network stop instead of
restart.

I'm done till I get back home this evening.

Have you tried adding PEERDNS=no to your ifcfg-device file? If that doesn't
work, you might be able to use NM_CONTROLLED=no as well.

Thanks,

Giving it a try now.

You haven't done what I've done intentionally, flag /etc/resolv.conf
immutable with "chattr +i /etc/resolv.conf" have you?

I do this to keep Network Manager and other busybodies from making unwanted
/ unneeded changes.

Hi,

I had trouble with this some years ago and remember someone posting how to
stop it.

I may have. If so, is there a way to undo it?

Thanks

I know that in Fedora, resolv.conf is now some symlink to a NetworkManager
file (I forget where).

Try doing ls -l /etc/resolv.conf, and see if that's the case in CentOS-7 as
well. (I don't use NM, so I'm not sure what the case is with it, as the
machine I'm using had that change made, if it was needed, long ago. :) )

If it does turn out to be a symlink, copy its information, if you need it,
then delete the file, then recreate it.

Hope this helps, but I'm not sure. It is a working solution in Fedora.

Hi, thanks, it does not show it being a sym link.

[CentOS] Unable to edit resolv.conf

Hello,

I changed ISPs and need to update name servers in resolv.conf.

I have tried nano, gedit, Webmin, system-config-network and it won't allow
me to make the changes.

I have Network Manager turned off and when I enable it , eth0 and eth1 have
no entries.

I enabled it, added the connections, but still no changes.

I'm stuck

That's cool! Didn't know they made something like that.

I only have one spare 5.25 and one spare 3.5. I think this TS130 has 2 -
5.25, 2 - 3.5 and 2 - 2.5.

I know they make a 5.25 to 3.5 adapter. Probably will just pick one of those
up for now but that hot-swap bay will give me options when I can expand
things a little.

Thanks!!

I think this will get me started, then I can buy an enclosure, a couple
extra, etc., when I recover from the auto expense.

[CentOS] Network Storage

[TE Dukes]

Hello,

 

I have looked into the various network attached storage devices and software
based solutions.

 

Can't really find one I like.

 

Would it be possible to add a couple HDs to my existing 6.8 server and set
them up as RAID drives?  If so, how would I keep it from mirroring the
system drive?

 

Just spent$2500 on a transmission for my truck, so I broke right know and
need to go the cheapest route.

That is a nice looking unit but pricey. They are $867 with no drives on
Newegg.

Think I'm going with the TS140. My TS130 has been pretty solid. I can get
one w/o a HD, Xeon processor,  for under $400.

I tried installing freenas as a vm on virtualbox last night for a test run
and got into a loop of reboots. I followed the directions in their
documentation. Never got it working. After about a dozen tries, I gave up.

It has me worried about buying all this hardware and not being able to get
it setup.

At $999 w/o drives is kind of pricey. I do like the look of hot swappable
drives. But how often is that needed.

I think I am going the DIY route. I have a Lenovo TS130 I may use. I'll need
to buy a couple 5.25 to 3.5 drive adapters.

The prices on a new TS140 w/o drives are pretty good. Both have the Xeon
processor.

The QNAP does have a lot of features that I'd probably never use. The only
issue I have is what would be the end of life support. Would that matter if
it's a backup device?
