OpenSUSE Network :: Literally ODD - Network Services Don't Work Every Second Boot?
Sep 14, 2010
I have an OpenSuSE 11.1 in vmWare ESX and every other boot I can't access any running network services (ssh, webmin, qmail, mysql, ...) from outside. I just need to login, reboot and voila - network services are working.I gradually updated to 11.2 and 11.3 by following the wiki with success but this problem remained. So I reverted to snapshot of 11.1 and now I would like to identify and solve the problem here first.I also looked at /var/log/messages /var/log/boot.msg /var/log/lastlog but can't find anything usefull. I will now compare those files from the working and non-working boot but meanwhile someone already has an idea or experience what could be wrong?
I have a router working as an access point for Internet access. It is used by sveral computers. Wi-Fi connection to Internet through this router does not work after boot on openSUSE 11.4.The cannection becomes established, shows IP address, access point MAC address,the signal level is high. But Internet is unaccessible with traceroute returns"the host is unreachable" message.
If to disable the automatic start of the interface and start it manually with ifup wlan0, nothing changes: the interface still does not work after first start.This is very annoying because this laptop is use by a girl who cannot restart interface. She says she cannot do anything with it.
In short: browsing the internet with domain names does not work. The long version: I've configured my network with DHCP and ifup. Ping works on my internal net and with servers in the internet. Dig work's too! I get the right IP to the requested domain. When i try to access the internet using firefox or even wget i get an DNS error. For example wget is showing the following error: Resolving heise.de... failed: Name or service not known. wget: unable to resolve host address 'heise.de'
Again dig show me the right IP and if i add the entry to /etc/hosts it work's too! I've even tried it with manually setup of ip address, nameserver and default gateway but with the same result. Switching off the firewall has no effect on this problem, too.
I deleted the firewall files "K09SuSEfirewall2_init", "K01SuSEfirewall2_setup", "S11SuSEfirewall2_setup" and "S01SuSEfirewall2_init" from "/etc/rc.d/rc5.d" in order to disable the firewall when rebooting.
As a consequence all network services are not working. I can't connect to any other machine nor to the internet.
I rebuilt the symbolic files based on the ones for runlevel 3, but still no network services are available.
Any suggestions how to make it work again? I'm using Suse 11.3.
I install from openSUSE-11.3-NET-x86_64.iso. Installation was succesfull, but after install all packet on test internet / update was error. And after log in in installed system internet not work. I use router with DHCP
I had Kubuntu 64-bit installed and decided to try OpenSUSE instead as I was having problems getting the audio to work on Skype. After installing OpenSUSE 11.3 (64-bit), I do not have network connectivity (Ethernet or Wireless)? Neither adapter can be detected? I thought the install would be fairly straightforward as Kubuntu 64-bit detected all the hardware.
I have both apache and tomcat services running, both in their standard doors (tomcat 8080, httpd 80). I need to setup tomcat to run on door 80 instead of httpd. I changed httpd door with success to 8180. Now I want to change tomcat6 door to 80, and I did that by editing server.xml config file of tomcat. After restarting tomcat, the system tells me it's ok, but I can see that it's not running on 80, nor at any other door. A simple nmap search confirm that. What should I do to have tomcat running in door 80?
I have a little bit of a problem, I run openSUSE as a server on a Dell PowerEdge T610. I use it for sharing files in a local network and as a web server accessible through the public IP (configured through router DMZ). Also, I use Teamviewer for remote control in order to avoid some compatibility and network problems. Generally the computer runs flawless but from time to time, as about once in two weeks, all network related services except the Apache server which runs just fine, and is still accesible, crash. The Samba share can't be accessed anymore, the Teamviewer is also dead and the only way to put everything back in order is a restart. The thing is I don't know if an error occurs since the server hasn't got a monitor installed, and more than that I do most of my work remotely (as in miles and miles away from the location) and it takes me quite some time to actually get there and see what's happening.
So, any ideas what might be happening? I belive that there might be some information in some of the logs, but as I am not an expert in Unix like operating systems I don't exactly know where to start from.
I have a question about /etc/services file. If I open ports in firewall, do I need to alter /etc/services file in order for certain apps to work?
kpasswd 464/tcp # kpasswd kpasswd 464/udp # kpasswd # Theodore Ts'o <tytso&MIT.EDU> # 465 is illegal used by eMail Server smtps 465/tcp # eMail Server #urd 465/tcp # URL Rendesvous Directory for SSM igmpv3lite 465/udp # IGMP over UDP for SSM # Toerless Eckert <eckert&cisco.com> digital-vrc 466/tcp # digital-vrc digital-vrc 466/udp # digital-vrc
Above example shows if 465 tcp isn't altered, Postfix MTA fails to listen on 465 tcp port. What if there's a bigger span 3000:7000 TCP/UDP, is there a need to alter each line by hand?
This is a thread I've moved over from the install forum and is hopefully more focused. Sorry if I have violated some protocol. Problem I have a new machine build configured to dual-boot Windows 7 and OPENSUSE 11.4. Network performance in Windows is very good but network performance in OPENSUSE is very poor.
I have an opensuse 11.3 install which I want to set up as a network boot server to install Solaris 10 on a Sun Ultra 10 client. According to what I've read, this requires rarpd and tftpd which I've set up on opensuse, but also bootparamd which I can't find for 11.3. It seems it was last included with opensuse 9.2. Does anyone know if it's available, if I could use the suse 9.2 version, or any alternative?
On Linux Mint (Gnome) i used to go to Network drive. that is on the right hand side of Nautilus there is a short cut for Network. in there i could see my network hard drive and other laptops connected to the network, and i could access my files. but on OpenSuse, when i open the network folder, nothing comes up. may be it needs some sort of configuration.
Currently my office use a Cisco Firewall which will only allow the ANYCONNECT utility to do the vpn connection. I found a Linux utility (OpenConnect) which will do the same thing, but allow me more flexibility with my networking needs.What I ultimately would like to have is to have a switch that I can connect any network device into it and be connected to the office. IE (my IP Work Phone and Computer) Currently I have is a computer with fedora 13 and two network cards eth0 (home network - connected to a router) and eth1 which I would like to connect a switch to. OpenConnect communicates fine and I can see the work network from the Fedora machine. It creates a vpn0 tun/tap device and I don't know how to pass communication to/from the eth1 device.
Do I try to iptables the ports for the phone and services I need on the computer? Or do I build bridge; and If I do what am I bridging. I have tried making a bridge from eth1 to vpn0 which reply's with unsupported device or something like that.Unfortunately my network skills are bit limited and my office says "it can't be done". Their solution is for me to buy a ASA5505 (or something device) and have a static IP. I would have to make it work as my router and even then it will only DHCP 10 ip addresses; which will cause a shortage of IP addresses in the house.
I'm planning to use Debian as the OS for a firewall machine, which will sit between my internet connection and the rest of my computers. Now my network is all wired, no wireless whatsoever. I'm using the onboard the motherboards cat5 socket which seems to be using the VIA rhine driver and I'm also using a 3com 100MBps card.
I can list the machine spec if you want but it's nothing special, an old Athlon 64 rig with 1gb ram and an OEM motherboard, it all seems to work ok apart from the internet doesn't' seem to work. Lenny seems to detect both cards ok and I even used the net install CD and it managed to download everything using the 3com card.
The strange thing is when I'm in Lenny, I can't seem to connect. I can ping google, but when I try and view a webpage, the browser just sits there with a while screen... Could it be that using 2 network cards is confusing Debian? Right now I've only got the modem hooked up the the 3com card, and nothing connected to the onboard network card.
After a recent update of fedora 15 (2 days ago) I lost my networkmanager icon in top panel completely. Then I check network manager version & found it's version 0.8.0.9997-5.git20110702. After this update I can't connect to internet by any means either via wired or wireless connection. When I try to open Network option from system settings it giving me an error: System network services are not compatible with this version.
I also try to open network-connection-editor by pressing Alt+F2 & typing: nm-connection-editor
But it not works as well, I can't see any existing network connection there, moreover I can't even manually add any type of network connection there including mobile broadband! Then I do some googling from my windows machine & found this thread- [URL]. According to this thread I try to do downgrading of following 3 packages-
Code: networkmanager networkmanager-glib networkmanager-gnome But I can't downgrade via yumex as there's no internt connection in fedora. so i do a trick of myself. yumex suggests me to downgrade them to previous version 0.8.0.999-2.git20110509 so i manually download those 3 packages from my windows machine & copy them to /var/cache/yum/... folder. After that I do downgrading via yumex. But even after downgrading problem isn't solved. Same things happening still. No networkmanager icon in top panel & no internet at present, there's no internet connection in my fedora 15 machine & I'm writing this post from my windows machine.
Moreover when I give this command in terminal: Code: sudo service network start it giving me FAILED status.
I am sharing some folders from my Ubuntu machine, using Netatalk and Avahi, over my network.I access these folders from my Mac using the AFP protocol.When all is well, my Ubuntu folders show up in Finder on the Mac and I can connect to them.But at random intervals, the Ubuntu folders will disappear. Sometimes they reappear a short while later.At other times, they wont appear until I go to my Ubuntu machine, and re-save (even if i don't change anything) the file:/etc/avahi/services/afpd.service.
I haven't been active in Debian for two years back when Lenny was still in 'testing' and noticed that for some reason it is no longer protocol to restart network services using the 'init.d' scripts. I also noticed the same for Ubuntu (which I don't use or could care about) and am trying to understand what is the correct way now for Debian and what changed? I did a search on Google but didn't turn up any results. Is it no longer correct to run:
I'm having problems with hackers from across the globe trying to get into our servers. Why? i have no clue. nothing of value in my servers worth getting.
Right now my service only does business with USA. So I'm trying to find a way to block all Non USA traffic. I called my hosting provider and they are unable to help. Said it was up to me to do this.
Well I've already taken care of the TCP Wrappers. by spawning a small C program i made that uses MaxMind's GeoIP system. to automatically deny access. Now i need to do something about all the other network connections that come in to services that do not use the TCP wrappers.
So i was wondering if IPTABLES have a way to spawn a sub proccess like TCP wrappers or if there was any other firewall software out there for linux that would let me achieve my goal.
I install openSUSE 11.2rc2 kernel 2.6.31.5-0.1-paeand hamachi-0.9.9.9-20.54.1, on previous version it's work fine, but now when i try to exec hamachi from console i have next message:
Code: Message from syslogd@admin-gw at Nov 5 10:24:53 ... kernel:[ 1165.793481] Oops: 0000 [#2] SMP
But i i select that address get i on (network Icon)
Ip address: 192.168.1.225 Subnet mask: 255.255.255.0 Domain: from 192.168.1.129 to 192.168.1.250
And i don't get Internet or can upgrade opensuse?
It is because i use windows 7 that (Porting web) between routes? (Other computer).
I use windows (Main system) with the same settings and i get Internet. So it can be compatibilty issue? Or need linux also need to change other things?
I have tried this both with 2 computer without Internet access.
I have before Mandriva 2010 Free and Kubuntu 10.10 that work with that settings. But I want KDE 4.6 so i upgraded to opensuse.
I have a system running a very basic LTS install (10.04). Ubuntu has been setup with very little additional packages. No GUI. Once it's booted to a prompt for the first time I add the following packages,
cups cupsys ssh pi memtester nfs-common aptitude safe-upgrade
At this time I don't have additional information on exactly what packages are installed. I did not perform the installs myself. I will update this thread when I get more details from my IT counterpart on how the system was setup.
This is used for a headless(no monitor, no keyboard) system running some custom applications.
Here are two problems.
1. If I plug into an ethernet network after I boot, the network never connects. I need to reboot with the network connected in order to get an IP. What is the service to "auto connect" to a network?
2. I have a network printer configured on lpd called myprinter. If I am connected to the network when I boot, I can print to this printer just fine using:
Code:
However, If I boot disconnected from the network and print to myprinter, the jobs obviously cannot print. They get spooled. Using 'lpstat -t' I can see that the spooled print jobs are assigned a job number and that myprinter is trying to connect. I shutdown, reconnect my ethernet network and boot up. All my printer configuration is blown away.
/etc/cups/printers.conf has been wiped out to look like this:
Code:
My 'good' printer configuration is copied to printers.conf.O
To recover from this, I need to stop cups, copy printers.conf.O to printers.conf, restart cups, and re-setup my network printer.
So, What causes my printers to get wiped out? I've repeated this on 4 systems with the same setup.
I had work well with opensuse 11 and the internet also work well but when I turn off my computer and then use the XP and work with it. I find out the connection with the internet doesn't work in the opensuse 11. I made a repair and format to opensuse 11 but without any change the net still doesn't work.
