i want the rpc server connect properly

thanks and bye

Hi,
Try telnet 127.0.0.1 9100 and tell us what you see

kindly have a look at this http://www.linuxquestions.org/questi...ubuntu-451282/

thanks

thanks for replay
i get this
trying 127.0.0.1
connected to 127.0.0.1
escape character is `^]`

and i expect there is another application try connect to it

From what i see your port is opened. because when you do ctrl and ] you would have telnet prompt "telnet>".
if it's not opened it's either saying "trying to connect .... " or so or " Unable to connect to remote host: Connection refused"

maybe you might want to see if your application is able to connect to anything at all

i've install videocache appilcation and seems could not connect to rpc server at this port 9100

i ask if another application than videocache is try to connect to rpc server

Could be...what other services do you have running on the server?? And the results of the "netstat -tulpn" command seem to be wrong, since it should also return the PID of all the running processes as the last column. Once you have the PID, you can do a "ps -ef | grep <PID number>" to find out what service it is.

Wild guess...do you have network printers? Port 9100 is typically used by network printers (been the 'standard' for HP for years...lots of other makers use it too), so CUPS or other print services may be conflicting. Would be far easier to change the port of your video app, than to change all the printers and CUPs.

i do a s aux |grep python and get

and i changed the proxy of my videocache to 1024 and ifaced the same error

Ok, so why are you doing that??? What is the PID # from the netstat command?? Grep for that instead. And again, do you have any network printers????
What does the proxy have to do with an open port?? Is the video server behind a proxy server?

You have two simple choices:

1. Find out what's using port 9100 now, and make it use something else (see previous post about how to find that out)
2. Change your video server to use a different port

None of these things involve a proxy server, and you didn't mention that before. Please run the commands given, post the output, and please post a clear description of your environment. We don't know and can't guess what you have running.

sorry iam not prof in ubuntu
i have ubuntu with squid server and now installed videocache application

is this command use to find out netstat -lnptu | grep 9100??

if it is i get this

tcp 0 0 127.0.0.1:9100 0.0.0.0:* LISTEN 1235/python

i don't have a network printers

You did not mention squid before, and is squid on the same server as the video app? If not, does the video server sit BEHIND or IN FRONT OF, the proxy? And what "videocache" application did you install? How did you install it? Where did you get it?

I'm guessing you mean "proficient", and you don't have to be...we'll help you, but you DO need to provide complete details.
Ok...so the process ID is 1235. Again, run a "ps -ef | grep 1235" to see what process is using that port, and AGAIN, either change it to be something else, or change your video app to be something else.
Do you have CUPS running on that server???? If so, try stopping it to see what happens.

at first i am sorry if i disturb you

iam unprofessional in ubuntu and to be serious with you i have an network with clients and i want to cache video to save bandwidth
i'd installed the squid and videocache app with the same server

i applied this command now and i get this
proxy 1200 1 0 17:13 ? 00:00:01 python /usr/sbin/vc-scheduler -s start
root 1499 1467 0 17:23 pts/0 00:00:00 grep --color=auto 1200

what is the CUPS?

this is the videocache's application website to cache video
http://cachevideos.com/

You're not disturbing anyone, but unless you provide DETAILS, no one will be able to help you. The same is true for asking a question about ANYTHING...would you just say "My car won't start...the check engine light is on...what can it be?" to a mechanic? Or would you tell them what kind of car, engine, symptoms, etc? This is the same thing.
You applied WHAT command?? You didn't put in what you ran, so there's nothing what you posted above can tell us.
Common Unix Printing System (CUPS). Again, if it's running, it *MIGHT* have something to do with a problem, since (again) network printing typically runs on port 9100. And are you ABSOLUTELY SURE that there are NO PRINTERS anywhere on that network?

AGAIN:

• Shut down any of the videocaching software completely.
• Run the netstat command, and grep for 9100
• Take the PID from that command, and run "ps -ef | grep <PID number>"
• See what process is running on port 9100
• Either stop or reconfigure that service to run on a different port.

And did you follow the instructions COMPLETELY on that website?? Because it tells you that the default port is 9100, but you can use any OTHER port above 1024. Have you just tried a different port?? And if you're not too familar with Linux, is there somone more experienced who could help you?

Hi, as root, issue 'lsof -i:9100' (note the adjacent : & the port, no space!). Will return the process that spawned the port.

From there, use - again as root - 'lsof -p <process>'. It will give you the list of all file(handler)s involved.

hth.

yeah i am sorry but i told u i am not prof in the ubuntu

i use this command ps -ef | grep 1027 and i get
proxy 1027 1 0 17:13 ? 00:00:01 python /usr/sbin/vc-scheduler -s start
root 1499 1467 0 17:23 pts/0 00:00:00 grep --color=auto 1027

and i am absolute sure there is no printer
and i'd changed the port to 1024 and after reboot i faced the same error of port 9100 with 1024
i expect there is a problem in squid.conf (note:my squid v2) because the problem had disappeared with squid3

i attached my conf please find out if there is a problem with it

in the videocache application the trace.log used to detect a problem with the videocache
so i checked it and get this error
may be this help u to detect the problem

iam sorry but the promoter of this application doesn't replay to my problem
