Topic: httpd: bad group name www

[larieu]

SME server 8 (from beta stage - but actualised to SME8 latest)
I had phpmyadmin from smecontribs 7
but I didn't use it
now I tried to update it to the latest one

Code: [Select]

yum update --enablerepo=smecontribs
(smecontribs point to sme8contribs; sme7contribs point to sme7 contribs)

after this and classical singnal-event....
I was not able to access any https webpage (https/mydomain/webmail, https://mydomain/wiki ...)
but

I found in logs errors that are related to php-pear-xxx

and I have tried

Code: [Select]

yum reinstall php-pear-Auth-SASL php-pear-Cache php-pear-Date php-pear-DB php-pear-File php-pear-HTTP php-pear-HTTP-Request php-pear-Log php-pear-Mail php-pear-Mail-Mime php-pear-MDB2 php-pear-Net-DIME php-pear-Net-FTP php-pear-Net-SMTP php-pear-Net-Socket php-pear-Net-URL php-pear-Services-Weather php-pear-SOAP php-pear-XML-Parser php-pear-XML-Serializer php-pear-XML-Util
php-pecl-Fileinfo

and then signal-event ....

now I am not able to login to server/manager
actually I receive on attached display this error (not in ssh - only on display)

httpd: bad group name www

on boot the only error is

Loading egw_domain.sql into mysql         Failed

apparently the email, ftp, ldap works ok

I am able to access ssh but no webpages

in /var/log/httpd/admin_error_log
I have only (apparently apache is running)

I have a full backup (backup to workstation) but I am not able to access it through server-manager
and also an affa backup to another station
that means I can recover some files if I know which ones

How can I find more errors to be able to find the root of the problem?

[larieu]

more on this

I have mailarchiva installed and that seems to work ok

but no egroupware, no awstats,

from ssh if I try telnet on port 80

Code: [Select]

Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused


mailarchiva works on port 8090 and the rest on prot 80 / 443 don't
apparently this ports are blocked
how to enable access to this ports from console
 

[larieu]

I have found that also roamng profiles don't work (and samba is also down)

and also the ppp connection (this seems to timeout)

if I scan the server from LAn I found services only on ports
21,22,25,53,139,143,389,465,515,636,993

no 80 443

[/code]

you should file a bug, no contrib/update should do this

anyway, please report the errors and the list of updated rpms

and I have tried

Code: [Select]

yum reinstall php-pear-Auth-SASL php-pear-Cache php-pear-Date php-pear-DB php-pear-File php-pear-HTTP php-pear-HTTP-Request php-pear-Log php-pear-Mail php-pear-Mail-Mime php-pear-MDB2 php-pear-Net-DIME php-pear-Net-FTP php-pear-Net-SMTP php-pear-Net-Socket php-pear-Net-URL php-pear-Services-Weather php-pear-SOAP php-pear-XML-Parser php-pear-XML-Serializer php-pear-XML-Util
php-pecl-Fileinfo


why?

now I am not able to login to server/manager

httpd: bad group name www

did you search the forums and bugzilla? I remember something about that..
do you have any other repo enabled other than centos/SME ones?

[larieu]

bug - I'll report
for moment I want to find some way to have apache on port 80 and roaming profile running


no other repo enabled (only standard ones)


httpd: bad group name www
Yes from there I had the idea to reinstall php-pear-xxxx

apparently apache start but some group perms ion / config files with changed permission don't let me to access it on standard ports

how to drop/restart firewall for test this?

[Stefano]

bug - I'll report

asap, please..

for moment I want to find some way to have apache on port 80 and roaming profile running

if you report a bug, you'll also find the solution

no other repo enabled (only standard ones)

another good reason to open a bug ASAP

httpd: bad group name www
Yes from there I had the idea to reinstall php-pear-xxxx

you did not report the error message.. you made a decision, we don't know why, you broke your server and we are not able to help you if you don't help us

apparently apache start but some group perms ion / config files with changed permission don't let me to access it on standard ports

did I say you to open a bug NOW?

[larieu]

http://bugs.contribs.org/show_bug.cgi?id=7124

done

can at least someone tell mow to safely disable firewall (and the put it back) ?
to test if the problem is related to this

[Stefano]

if you update only php-pear related rpms, firewall and its rules are untouched, so you can safely ignore it

[larieu]

unfortunately I didn't observed immediately that the servr-manager is broken
and I hat tried other things, too

but now I am not able to remember everything

[Stefano]

Code: [Select]

history

will help you

[larieu]

that the problem

I don't understand why I have some missing history
The history show me only something like up to 2 days ago
and after the problem

and I am sure that I have done something else there

for example yum update --enablerepo=smecotnribs
I don't find it
or the long yum reinstall php-pear.... one

I have done something in that period which broken the server-manager

what I remember is that after signal-event
I was forced to go to IPKVM to issue one "cancel" after something like half an hour of not booting
there I have noticed the
httpd: bad group name www

otherwise I don't see it in any place

You might be better off rebuilding the server with a fresh install of sme8 and restoring from backup & reinstalling contribs, compared to the time & effort (& technical unsureness on your part) that will be involved to troubleshoot this & fix your problems.
Either way there will be considerable effort required.

If you do decide to do a restore, then do a test restore first (on different hard disks) to prove your backup is good, BEFORE wiping the current system.

[larieu]

my problem is that the users had tons of mails from the moment I have the last trusted backup (now are almost 4 days)

most probably I'll need to proceed like last time when I had a corrupted hdd

I'll prepare a new temporary one
over week-end I'll stop everything
I'll copy all relevant data from this server to the temp one
(users, mails, databases... = /home , /etc/e-smith , /etc/users.+ group + shadow... like affa does)
then when all is ok on the temporary one I'll use affa to put back on the real server

it exist any other verified method to move only users(+ userdata) + databases?
no any contrib/ or settings

on actual server I can do an USB backup
but I don't know if from backup I can recover only specific data

now just for testing
how safely drop firewall and the how to put ti back - to test this also

show output of
service httpd-e-smith status
service httpd-admin status

too see what iptables rules are configured see ouput of
iptables -L

[larieu]

Code: [Select]


# service httpd-e-smith status
down: /service/httpd-e-smith: 0s, want up
# service httpd-admin status

httpd-e-smith it is down
but

even if I have issued restart
no relevant data in error log messages or in access log

the intricate thing is that my mailarchiva works (default contrib on port 8090)
that mean the base apache is up (httpd-admin) 

I have used
iptables --list
( is equivalent - I think ) - everything seems ok there

service httpd-e-smith status
down: /service/httpd-e-smith: 0s, want up

Now that web services has been started did you run a port scan again ?
AFAIU without the appropriate service running the ports will not be open (& accessible).

that mean the base apache is up (httpd-admin) 

httpd-admin is your server manager

httpd-e-smith is your basic web server

Do you have another instance running ?
Show output of
service httpd status

When you say you did the classic "signal-event", that is rather unclear, as there are many possible signal-event's you could have done.
Do you mean
signal-event post-upgrade
signal-event reboot
???

[chris burnat]

A bug report has been opened in Bugzilla, it is being attended by a Developer, please follow there.  Duplication of information is counter-productive.
Thanks.

Mary, if you want to help troubleshoot, please do so in the bug tracker. Not here. You are not helping by undermining the bug tracker.

"0s, want up" almost always indicates a service which is crashing immediately on startup.

"httpd: bad group name www" - this is very likely the core problem. Why does this system not have a group 'www'?

All followup to the bug tracker please.
