General :: Sync Server And Client - Wait Over A Minute For The Changes To Be Downloaded?
Oct 17, 2010
I work as a part-time consultant developing webpages, both back end and front end.When developing a back end application I'm using a server running ubuntu server edition to host the application while I'm developing it.The problem comes when I want to upload my changes to the server, now I'm using Dropbox both on the client and the server, the problem is that sometimes I have to wait over a minute for the changes to be downloaded (when I'm working out-of-home that is) so I'm looking for a better alternative. My options seems to be:Some open source version of dropbox which syncs directly to my server (haven't found anyting that sounds viable though)
Mount my server via some protocol (NFS, SSHFS etc)
Push changes manually via FTP, git, svn or something else
I'd like the sync to be as transparent as possible, meaning I'd like to do as little manual work as possible.The client I'd like to connect runs either OSX or Ubuntu.The ultimate solution would be to use NFS + VPN though that would be alot of work to set up and also I don't like the security in NFS (matching UID's doesn't seem very secure to me)

Have anyone used an email client that stays in sync with a free Hotmail account? I have setup Claws Mail but when I delete an email within the client it remains on the server. I remember this being the same for other email clients. Is there any client that will stay in sync? If I delete an email from within the client it will also be deleted from Hotmail's web bases interface.

I have a server listening on incoming client connections. Once the client establishes SSL connection with the server, the server waits on read() from the client. Only Client can disconnect the connection. I want to have a timer in the server program to wait for x secs after read() and then disconnect the Client connection.

I've discovered Firefox Sync a while ago, and it's absolutely awesome. Now of course I'd like most of my software to work this way! So is there a way to get the same behavior with Thunderbird?

I have a scenario where I want to monitor at disk performance (cpu and memory also if possible) on a RHEL 5 server functioning as a NAS. I have several machines that backup content to this server via scheduled cronjobs and I'm curious to see if the machine is hitting a bottleneck under load.I attempted to setup cacti on one of our LAMP servers and had a miserable time due to running PHP 5.3 and deprecated function issues.Can anyone recommend an alternative keeping in mind I have only very basic experience with SNMP?

Just started to encounter this problem recently: after entering a valid password for a given user during an SSH login, it takes at least one minute to get to a prompt. It usually takes only a second to check the password and drop me to a prompt.
I haven't had this problem before - it seems to have started this week. Only thing I've done this week is run updates. Has anyone encountered this problem recently? Any ideas or fixes that may help solve this? Server info: not exposed to the Internet, only running SSH, fully patched version of CentOS 5.5 x86_64.

This has been raised as redhat bugzilla bug 583054 - seeI am posting here in case anyone else has dealt with a similar problem. In brief, I have a print server running Fedora 12/CUPS dual boot WinXP. The attached printer is a Canon BJC-4100. When the server is booted in F12, it takes over a minute for a networked Fedora 12 box to bring up a print dialog, or for the printer to start after a page has been submitted. When the print server is booted in WinXP, printing is immediate.
Tim Waugh identified the problem in the CUPS Troubleshooter output:
'D [10/Apr/2010:09:00:20 +1000] cupsdNetIFUpdate: "lo" = localhost:631',
'D [10/Apr/2010:09:00:37 +1000] cupsdNetIFUpdate: "eth0" = 192.168.0.199:631',

I'm building a simple(?) socket server using threads to serve up a few requests. The spec is such that I have to listen to three ports at once, so I decided to use pthread to create three separate threads that would wait for connections, then spawn new threads to handle them.
The problem is that when I do this, for some reason the program never enters the wait loop and instead terminates (All three threads did get created since the messages get printed properly.) It gets to the line which prints "???", but not the line after the accept() call.I don't see an open port when I check for one either so I'm 99% sure they're terminating.Basically I have a main() method which has three calls to pthread_create, which should result in three threads being run that all wait for connections (listenOnPort). After each thread creation I print some info to make sure it's actually being created.
By the way, when I just run listenOnPortwithout threading, the server appears to enter the loop correctly and seems to be waiting for requests. It's only when I run the functions as threads that the problem seems to happen.The source is attached below. Any help will be appreciated. Much of the code is borrowed from a website (I can't post it because I am new here.) You need not worry about the handler_ methods because those are just methods that are run by the threads themselves.
Also--the original source was in C and I changed it to C++. Should I just use C?
server.h Code: /*
* server.h

I have x11vnc server set up on my desktop PC. I can boot the computer and connect at the login screen if I want to. I can login to my computer as usual. But after about 1 minute of logging in, the computer logs off as if pressing Ctrl+Alt+Backspace and returns me to the login screen. This cycle repeats when I login and I have to kill the x11vnc process or remove the command from /etc/gdm/Init/Default.Have tried so many things now but the end result is the same. I have Ubuntu 10.10 fully updated and x11vnc 9.10-1 from the default repos. I am using the following command in the /etc/gdm/Init/Default file:
Code:
/usr/bin/x11vnc -rfbauth ~/.vnc/passwd -rfbport 5901 -display :0 -forever -bg
I don't think it matters now whether I add KillInitClients=false into /etc/gdm/gdm.conf-custom or /etc/gdm/gdm.conf because of the x11vnc version I have. The manual says its not really needed. But I have tried this too with no better luck.The computer will still log me out after about a minute of logging in. It can be between 1 min to 1.5 mins.Running out of ideas and have tried the -noxfixes and -reopen commands.
Why does x11vnc crash out (or it may be gdm or x server?) after about a minute of logging in? If I am currently viewing my desktop through VNC viewer on another computer, it will still crash out after 1 min of log in, and lose the connection. I can reconnect through VNC again but I have to log back in to the remote computer and it will just log out after another minute.At last, in 2 days I have finally solved it. As simple as creating my own version. The x11vnc 9.10-1 version my default Ubuntu 10.10 repos is buggy. Here's my fix (I used this site):
1. Downloaded latest x11vnc dev build from above site (x11vnc-0.9.13-dev.tar.gz at time of posting)
2. Extract it
3. Open Terminal > sudo -s > enter admin password
4. cd LocationOfExtracted folder

I'm running my website on a linux server. I'm using a mac. Apparently, mac mail has a bug where it creates too many imap processes.
Since I'm on a shared server with a 25 process limit, with 3 email accts x 4+ processes each = a lot of problems!
I'm trying to write a cron job to delete imap processes every minute.
I've tried two things
1) following this blog's advice [URL]
Code:
killall imap
i realised it was imapd not imap, but i tried another method anyway
2) create a kill-imap.sh file in my server folder.
Code:
#!/bin/bash
/usr/bin/killall imapd
then executing the file from the cron command /kill-imap.sh
both these cases, it didn't seem to work!
I would get a daemon emai reply with
imapd: no process killed
just to give more info, the existing imap processes look like this
/usr/lib/courier-imap/bin/imapd /home/sitename/mail/sitename.com/emailusername
honestly, I'm not too experienced in this, and i've searched the net without luck. can anyone advise what i'm supposed to do to kill these imap processes every 5 min via cron job?

Previously I had posted a question on how to make it run every 7 minutes between 7 and and 11pm.However now I found out what I really need is every 7 minuted between 7:30 and 11pm BUT it has to be every 7 minutes, it cannot reset itself on the top of every hour, so the */7 wont work.How can it that it will be every 7 minutes, so it will go at 7:30, 37,44,51, 58, 8:05, etc..

I have a doubt regarding the 389 Server Client Architecture. Say, I have 389 Server working and I have few Linux Clients. Now you say that if 389 client is configured it will login through credentials which is configured in Server. So what about the local Users on that Client.How will normal users in the Client login?
