CentOS issue opening port 8080

is something using that port?
what happens when you do netstat -at | grep 8080 (as root)?

again I am not a server guy, once I log into the server from command. If I add the command you mentioned it does nothing. I also tried this site http://www.yougetsignal.com/tools/open-ports/ and it says 8080 is closed at the IP I provided earlier. I have smartfoxserver running on that port and it has always responded in the past. Thanks for your help

see attached screen shot
Screen-Shot-2014-12-24-at-10.55.19-AM.pn

it returned no output which means there is nothing using it - which agrees with that site you checked
netstat will show ports that are being used; grep is like a filter so it is looking for a pattern match 8080

the server is probably not running
not familiar with the application and not sure where it would be installed (you can basically extract the files anywhere from what i'm reading)
try this - as root, do find / -name "sfs2x*" -r and see what it returns

I just get an "unknown predicate" message. Is that exactly how it is to be entered? find / -sfs2x* -r

put quotes around the file name pattern as it is above

[root@server1 ~]# find / -name "sfs2x*" -r
find: unknown predicate `-r'
[root@server1 ~]#

sorry...leave out the -r
many commands use -r for recursive but for find it's the opposite; you put options if you don't want recursive

[root@server1 ~]# find / -name "sfs2x*"

ok...now you found the install folder - /opt/SmartFoxServer_2X/SFS2X

now try this:

cd /opt/SmartFoxServer_2X/SFS2X
./sfs2x-service start

Starting sfs2x-service
[root@server1 SFS2X]#

is the site accessible now?
if you do netstat -at | grep 8080 again does it show anything?

[root@server1 SFS2X]# netstat -at | grep 8080
[root@server1 SFS2X]#

nothing... How do I get it running there again?

looks like it didn't actually start

try this:

cd logs
ls -lhrt

is there a file there dated a few min ago?

ok good

cat smartfox.log

only 219 bytes so it's not much; maybe there is something useful as to what's going on

hmm...appears to be running; wonder if it's on a different port
what about just netstat -at in case it's running on a different port

has anything changed on this server?
did someone else configure smartfoxserver?

i had a group in the Ukraine looking at this for a while, wonder if they messed with something.. any ideas for fix?

offhand, no
i've been going by documentation as i never worked with this package before

Anyone with Smartfox and server exp, much appreciated?

I would also look in the log file smartfox.log.2014-12-23-12 and I would also look in /var/log/messsages after you try and start the smartfox service.

Do you know if you configured it to listen specifically on the IP address 162.217.100.226?

When you ssh to this server do you ssh to the IP address 162.217.100.226 ?

Please provide the following output:

grep 8080 /etc/services
lsof | grep sfs
cd /opt/SmartFoxServer_2X/SFS2X

Hello,

It seems that your problem is the SELinux. Please post the output of the command:

sestatus

Select allOpen in new window

I guess it would be enabled. Then grep the Audit errors:

grep AVC /var/log/audit/audit.log | audit2why 

Select allOpen in new window

Cheers,
K.

sh sfx2*
means you do not have classpath set properly and java application does not initialize.
install mc (midnight commander)
check .jar files around if any has missing classes inside, look in the script and add that jar file to your classpath in the script.

[root@server1 SFS2X]# sestatus
SELinux status:                 disabled
[root@server1 SFS2X]# grep AVC /var/log/audit/audit.log | audit2why
-bash: audit2why: command not found
[root@server1 SFS2X]#

selinux = disabled
so nothing interfering
iptables = disabled
no news here

It is plain and simple - the application itself does not start. do more RTFM, or try to find classes with mc, or unzip or whatever.

Not sure why, it WAS running just fine. I dont know why it stopped responding.. I dont seem to be able to access anything at 8080 port almost like nothing is there..

[root@server1 SFS2X]# netstat -nl | grep -- ^tcp
tcp        0      0 0.0.0.0:21                  0.0.0.0:*                   LISTEN      
tcp        0      0 0.0.0.0:22                  0.0.0.0:*                   LISTEN      
tcp        0      0 :::3306                     :::*                        LISTEN      
tcp        0      0 :::22                       :::*                        LISTEN

Ok if selinux is disabled this cannot be the problem..

Can you post your start script here ?

While checking on the Install instructions I've come across with this can you check it out:

All unix commnds are in lowercase so you need to type "cd SFS2X" not "CD SFS2X".

I'll also suggest you to upgrade  to the latest patch version 2.9.2 available from the site.

as if nothing was there

[root@server1 SFS2X]# cd SFS2X
-bash: cd: SFS2X: No such file or directory
[root@server1 SFS2X]#

You are already in the SFS2X directory. So you can omit this step.

Will you please install the 2.9.2 update ?

You have either bad disk (check with smartmontools)
Or you had unexpected powerdown and did not undergo fsck after

Either way a JAR file is corrupt to no good.

1) check your disk or raid with smartctl
2) run fsck -f against partition where sfs2x-lib.jar resides
3) Once hardware and system is confirmed fixed you can reinstall missing jar from the vendor.

Installed

Is disk and filesystem OK?

UnZip 6.00 of 20 April 2009, by Info-ZIP.  Maintained by C. Spieler.  Send
bug reports using http://www.info-zip.org/zip-bug.html; see README for details.

Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir]
  Default action is to extract files in list, except those in xlist, to exdir;
  file[.zip] may be a wildcard.  -Z => ZipInfo mode ("unzip -Z" for usage).

  -p  extract files to pipe, no messages     -l  list files (short format)
  -f  freshen existing files, create none    -t  test compressed archive data
  -u  update files, create if necessary      -z  display archive comment only
  -v  list verbosely/show version info       -T  timestamp archive to latest
  -x  exclude files that follow (in xlist)   -d  extract files into exdir
modifiers:
  -n  never overwrite existing files         -q  quiet mode (-qq => quieter)
  -o  overwrite files WITHOUT prompting      -a  auto-convert any text files
  -j  junk paths (do not make directories)   -aa treat ALL files as text
  -U  use escapes for all non-ASCII Unicode  -UU ignore any Unicode fields
  -C  match filenames case-insensitively     -L  make (some) names lowercase
  -X  restore UID/GID info                   -V  retain VMS version numbers
  -K  keep setuid/setgid/tacky permissions   -M  pipe through "more" pager
See "unzip -hh" or unzip.txt for more help.  Examples:
  unzip data1 -x joe   => extract all files except joe from zipfile data1.zip
  unzip -p foo | more  => send contents of foo.zip via pipe into program more
  unzip -fo foo ReadMe => quietly replace existing ReadMe if archive file newer

definitely outside of my common understanding.

Hi,

I've installed it on my test CentOS 6.5 ssytem. The install was OK. My steps were:
 
- you need to be root to complete setup so make sure you either logged on as root or be root suing "su -"
- Issued "uname -a" (Now I know that I have an x86_64 system)
- Downloaded the tar file for the 64 bit systems.
- I've cd'd to the filesystem root: "cd /"
- Started unzip: "tar xvzf /root/SFS2X_unix_2_9_0_64.tar.gz"
- Then changed to server install dir: "cd /SmartFoxServer_2X/SFS2X"
- issued ./sfs2x-service start
- issued netstat -anpt | grep :8080
tcp        0      0 :::8080                     :::*                        LISTEN      3265/java

So host is running. It seems that your install file was not complete or you did ot have root access while installing it.

thanks.. I will uninstall and reinstall and let you know how it goes..

Uninstall?
Just install over same data files... And do not run java as ROOT ?

Gheist/Kerem, if I install this over the same data will it replace my existing config file? This is the concern as the config file already has  room data, etc that I do not want to replace. Or do I need to somehow extract this config file and replace it later?

How could we know where configuration is :S
Did hardware come out clear?

Sorry, not following. Please remember your like a college professor talking to a 4 year old here in the networking world. :(

First you need to diagnose hardware:
install smartmontools (on by default)
update-smart-drivedb (download new drive health database)
and run smartctl -a /dev/sda (or where your disk is)

No need to do anything after unless fixed - seek new disk, update firmwares -etc

then force fsck on the filesystem that holds /opt (boot in single mode and fsck -f)

(again - ask fro more, but no point proceeding unless filesystem is healthy)

Once we have hardware in working condition we can proceed - rename program directory and do a new clean install
If something is missing / copy files from old installation
If it goes bad - move new installation out of the way and return to old one.

It seems command line would be a tough option since i am not a professional in Linux servers so rather remote connection looks much better option to control the server.I have a Centos6 server with internap, however we have been using terminal
or console with command prompts which I not very expert with .I would like to have remote desktop installed on the server so I can use the GUI interface of the system & do what I need to .When contacted the server guys from internap they said we need X server for the same , on other hand they also mention it would not be required because server comes with remote ssh connection.Not sure about what this is & how I can use remote ssh to connect to server remotely from windows computer ?

Sorry, but this is before any GUI can be started. Do you often complain that system bios or windows chkdsk run in text mode?

You do not need X server, more likley you need NX server or X11 forwarding that work over SSH discretely.

Can you suggest a link or direct me to process for how to install NX server or X11 that work over SSH ?

That will not help you to check file system

All missing is xauth package on system and X11 tickmark in putty and X server like Xming on your windows machine

very professional and knowledgeable
