Networking problems / VNC no ping reply

Hi,
I'm trying to vnc between my macs. Server is a MBP and the client is a G5 iMac. Basically I can see the server in the server list on the client (JollyfastVNC) but when I go to connect it spends ages working out what to do...
I tried to ping the server and there's no response. I've checked and the firewall is turned off on both machines. The server can ping the client no problem but the other way round doesn't work.
Any ideas?

A couple of questions:
(1) Are the computers on the same subnet, or is one at a remote location and you are traversing the internet at large?
(2) Did VNC ever work for you between these two machines before upgrading one or both to 10.4.11 and/or 10.5?
(3) Are you using the built-in vnc server capability in the MBP's Sys Prefs' | Sharing (in 10.4.10, where I'm at, you need ARD enabled in the services panel and VNC created and enabled in the firewall panel on the server machine, at least when the firewall is enabled -- but even tho' your firewall is off, I'm betting you still need some stuff set up in the MBP's Sys Prefs | Sharing | Services | ARD | Access Privileges), or are you using a third party server app?
(4) What IP address/subnet mask/gateway does the MBP's Sys Prefs | Network | TCP/IP have? If on the same residential(?) LAN, how does that compare to what the iMac has? How is the network address space defined in the router (router's 192.168.x.x address, subnet, DHCP address range, DHCP enabled/disabled)?

[Solved] Network problem, unable to ping, dhcpcd issue

Friends:
Issue on hand.
I upgraded Arch which is running as guest inside VirtualBox.
When machine boots up I don't have access to network.
I cant ping yahoo or google or any site.
The following steps work for regaining network access back
cat /run/dhcpcd.pid
180
kill -2 180
dhcpcd
now ping yahoo.com works fine
So not sure why this problem.
I am willing to put out any log information. I don't know what to look for.
Please help.

I'm not sure where the idea to get the pid to kill dhcpcd came from - it seems a very roundabout way of doing the following
# killall dhcpcd
# dhcpcd <interfacename>
However this is a bit beside the point. dhcpcd looks like it is starting from a dhcpcd .service file and failing there. When you restart it, you do so without specifying any interface name and it works. This suggests to me that the service file is using a interface name, and an incorrect one at that.
This is all just suspicion to be verified:
1) you have [email protected] enabled
2) you have "predictable interface names" ... which ironically means I can't predict what they'd be, but it would start with something like enpS***.
If correct, there are three possible solutions (choose only one):
1) revise the service to not specify an interface,
2) revise the service to specify the correct interface which you can determine from the output of `ip link`
3) use the udev rule to keep "old" style interface naming.
(edit: as an aside, I had the same reaction as WW to the "please help" in the title)

Odd Network Problem

Hi,
I have a strange network problem, can anybody help?
Basic configuration
I have three networks 10.190.0.0, 10.192.0.0 and 10.193.0.0 joined by a single server running Solaris 11 B64a with a dual port intel card and onboard intel card (e1000g0/g1/g2) each port is plugged into the gigabit port of a seperate Dell powerconnect switch.
they have ip addresses of 10.190.0.2, 10.192.0.1 and 10.193.0.1
The problem. I have connected from a remote machine through a solaris router machine on the 10.190.0.0 network to a computer on the 10.192.0.0 network (Beyond a switch).
The terminal works fine!
if I ping the 10.190.0.1 which is the other router beyond the box with the three network interfaces packets are not seen by the pinging box. However, if I snoop the interface on the three interface router I see both the ICMP echo requests and replies.
After a considerable length of time 10-30 seconds, a load of the packets suddenly appear on the pinging machine and then continue normally.
I would like to understand:
a) where were the packets during the time between the snoop seeing them leave and them arriving at the destination?
b) why does the terminal not suffer any delays?
We are suffering with a lot of strange network issues at this new site and I am trying to figure out if its the new dell switches, the solaris network stack or something else entirely!
Anybody got any idea whats going on?
Please Help I am baffled.

It may just be the pinging machine has received the packets, but it will not display them on screen until it has found a name for the remote IP address (or until it times out waiting for one).
Do you get the same behavior with 'ping -n' ?

Networking problem after a zone is created and installed

Hi all,
I've got a networking problem after a zone was created and installed on a Solaris 10 box. The box was configured with two NICs, one (e1000g0) with a public IP address, the other one (e1000g1) with a private IP address and connected to a local switch. All worked fine so far.
Then I created a local zone with shared networking (e1000g1). The zone has a private IP address which is in the same subnet as e1000g1 on the global zone. After some time, I noticed that I could not access (ssh, ping) the global zone. Then after some time, the global zone became available. The problem happened quite frequently.
Also I observed that: 1) When the global zone was unavailable from outside, it was available (ssh, ping) from another box within the same subnet (e1000g0); 2) If I shutdown e1000g1, the problem was gone.
Any idea what caused this problem?
Many thanks,
Xiaobo

It was a route problem.

Time Machine spends hours partially backing up and then fails with "Time Machine couldn't complete the backup due to a network problem." Tried suggestions I've seen on the forum.

Time Machine spends hours partially backing up and then fails with "Time Machine couldn't complete the backup due to a network problem." I've tried various suggestions I've seen on the forum but nothing has worked. TIme Machine worked fine for the last two years and just suddenly started having this problem every time. The only thing that was a little different is that the computer was off for a week while on vacation and then I added a large amount (20 GB) of photos. Now the requested backup size is 82GB, which is large, and process proceeds very slowly for 2-3 hours before failing with the message mentioned. I have more than enough available backup storage space for it. Before failing, Time Machine has backed up no more than 12GB or so of the backup. It fails during different files each time.
I've turned off the computer sleep feature, and I've checked that the NAS is set to never automatically power down. I normally backup over Wi-Fi, but I've also tried connecting to Ethernet and it still has the same problem. It's odd because I also have a MacBook Pro that is still backing up fine to the same NAS using the MacBook's Time Machine.
I am using an iMac with OS X 10.6.8 and an Iomega StorCenter ix2-200 NAS.
I have system logs that I can share if helpful. The logged messages vary a bit from run to run, but here are some messages that I've been seeing:
I always get this message near the beginning of the backup:
Event store UUIDs don't match for volume: Macintosh HD
I've gotten this messsage a number of times:

That looks like a problem was found with the file system (data) on the TM disk. I don't know the details, but OSX tried to recover it from the journal, and found extra data on the drive. Likely a result of the incompatibility mentioned above.

Something caused a disconnect. Can't tell from the log what it was.
I doubt it's a problem with something in OSX being damaged or corrupted, but reinstalling OSX isn't a major hassle, so might be worth a try.
To be incompatible with Snow Leopard, this NAS must be at least a couple of years old. It may be beginning to fail.
Contact the maker. See if there's an update to make it compatible with Snow Leopard. If so, that might fix it.
If not, or if that doesn't fix it, see if they have any diagnostics that will shed any light.

Upgrading OS Mountain Lion - Network problems

Dear all,
I've upgraded my iMAC last week-end. Good job
But... big network problem with ADSL connexion via ethernet
I've installed a CPL network at home because WI-FI range is blocked by big walls. Then no problem before (Modem Belkin connected on time machine and all devices (apple tv, Imac,...) linked by CPL).
WHen I've installed Moutain Lion, no more possibilities to connect throughout Ethernet (no DHCP renew).
Then I've reloaded a WIFI connexion. No problem at this time since this morning. I need to disconnect and reconnect the connection 4/5 times and It's no stable ?
Do you have an advice ? I really would like to find the stability of a CPL-Ethernet connection.
Thanks

According to the "FAQ on rootnex bind warning"...
http://groups.yahoo.com/group/solarisx86/message/16887
... this is a bug in the "bcme" driver. The FAQ lists a way to
suppress the warning and return a "success" result from
dma__bind() anyway, but I think this could lead to data
corruption.
I'd try to remove Broadcom's driver, and use Sun's "bge" driver
for Broadcom BCM57xx NICs instead (I'm assuming Sun has
fixed their "bge" driver and handles dma__bind() failures).
To use Sun's bge driver you probably have to install a pci device
alias to /etc/driver_aliases for your Broadcom NIC:

LaCie MiniHD connect network problem

I have a LaCie MiniHD connect in my local network. Did everything LaCie told me to do so I could write to the USB attached LaCie drive.
Formatted the drive in OS X EXtended but not journalized.
Tried to connect via smb://MiniHD.smb.tcp.local and the network told me to enter my ID and Password, I don't know why.
So I brought back the disk drive to my mac and changed the whole drive permission to read and write for everyone.
Brought back the drive to my TV and now I could transfer anything from my mac to the drive.
I was glad of that, but having shut down the drive and the MiniHD connect, when I opened it again to transfer something from my mac to the drive, I still got the same problem again with the same message.
"One or more elements cannot be copied to "LaCie_750" because you don't have the permission to read. Do you want to copy the elements you are authorized to read."
I suspect the software on the Lacie MiniHD connect to block OS X when it initialises the drive on startup.
In particular I see a folder named _HF2VN~W appearing in the root level of the drive.
Can any one help me with thi samba network problem on Mac OX 10.6.5?

I have since had a reply from LaCie to say that this issue has been identified and is being worked on - however I'm afraid that I don't have any timeline for when this will be fixed.

Uploading using Adobe Premiere Elements 12 Network problems

Hi,
Is there a place in Adobe Premiere Elements 12 that we can insert our company proxy details, the reason being. When I go to Publish and Share and click "Social Websites" and want to upload a video to youtube and push next it gives the following error "Online Services encountered an error. The services will be terminated or paused if possible."
If I use a 3G card it allows us to upload. Our network must be blocking this link or programme, yet we have made sure from our side adobe is not blocked on the network and I have access to all websites.
My question is can we insert proxy details somewhere or can I get the link of where that link is taking us to when pushing next trying to upload with youtube via adobe . I know it is going to youtube but I need the exact URL to make sure we allow this link to work.
Anyone have the answer for me?

[Solved] Network problems installing Arch

Hello everyone. I'm trying to install archlinux-2013-03-01 and I can't get to even start the installing process due to network problems.
I'm using a wired connection with DHCP but when I ping google or something it gives me the 'bad address' error (not the 'unknown host' error). I typed 'dmesg | grep r8169' (r88169 is the module for my Gigabit Ethernet driver) and the output says it's loaded, so it's not a kernel module problem.
If I type 'ip link' it says my interface is called eth0. So then I type 'ip link set eth0 up' and it says is up but again, I can't ping anything.
If I nslookup something it gives me my home address.
I even tryed to load the .iso with the option ipv6.disable=1 and still nothing.
Any help will be appreciated, thank you.

Thank you both for your responses.
I thought this was weird too, but I can't see any interface with the new network device naming scheme. According to the wiki I must have an interface called something like epn2so but if I type 'ip link' I only see:
1: lo: <LOOPBACK> [some more info]
2: eth0: <BROADCAST, MULSTICAST, UP, LOWER_UP> [some more info]
link/ethernet [my mac address] brd ff:ff:ff:ff:ff:ff
I think eth0 is the right name because if I type 'ip link set eth0 up' it gives me no errors and I can see ...UP, LOWER_UP> when I type 'ip link'.
@WonderWoofy: I don't have any Ip address when I type 'ip addr'. I don't know what could it be. This is the first time I have issues "configuring" internet with DHCP and believe me, I've tried hundreds of different distros and configurations.
PS: I wrote [some more info] because it's kind of a pain in the ass copy exactly all the output due to I can't ctrl + c anything in the installing procees. Should I copy the output of any particular command so you guys can see it? Thank you.

SR520, ping reply

Hi,
Not very familiar with the ZBF on the SR520, can anyone please provide me with a config enabling the SR520 to send ping reply´s.

Zone-based firewall configuration can be confusing, especially if one is used to older CBAC-type FW configuration.
Your best resource for this problem is the
Zone-Based Policy Firewall Design and Application Guide
http://www.cisco.com/en/US/products/sw/secursw/ps1018/products_tech_note09186a00808bc994.shtml#app-b
Appendix B has a sample config that would allow ping replies.
There are four basic steps in setting up the firewall.
1) Define the zones
2) Define the class maps that identify traffic between zones
3) Create a policy map that defines the action to take on the class map
4) Configure the zone pair and apply the policy
In Appendix B, you'll see the class map specifiying what traffic to inspect. The names of the class-map and policy-map could be anything.
class-map type inspect match-any L4-inspect-class
match protocol tcp
match protocol udp
match protocol icmp
The policy map here indicates what action to take, and in this case, the only action is to 'inspect'.
If it was 'drop', the connection would be denied.
policy-map type inspect clients-servers-policy
class type inspect L4-inspect-class
inspect
Hopefully that helps!

Snow Leopard Network Problems

Hi all.
I'm setting up my second Snow Leopard Server machine and I'm having the most frustrating networking problems.
I'm setting up a server with two NICs, and for some bizarre reason connection will NOT work. Trying to ping within the subnet of the inoperative connection produces "no route to host" errors. Switch the IP configurations between the two NICs, and the problem follows the primary configuration. The same network settings work correctly on a different machine, so the problem is definitely software.
I can't help wondering if this is related to source-based routing in 10.6. But I've tried flushing the routing table to no avail.
This exact same issue happened with the other Snow Leopard server I set up. After a few days of idling, the problems magically resolved themselves. Unfortunately, I don't have time for that to happen with this server.
Any suggestions?

The forums are littered with dual-controller subnet routing discussions; it's a very common issue.
Easiest fix: don't use a Mac as an expensive (and slow) IP router (or NAT box). Use an external firewall.
If you really want to wade into IP routing (and do you actually have enough network traffic to warrant lighting up two gigabit Ethernet connections right now?) then poke around for the existing discussions of setting up the ordering of the controllers and establishing subnet routing live and after each reboot.
I'm probably going to end up writing an article and posting it, as this arises way too often, and folks are understandably having issues with locating the problem given that most (understandably) don't know they need to look for subnets and static routes and such.
Existing threads including [this|http://discussions.apple.com/thread.jspa?messageID=10688941] and [this|http://discussions.apple.com/message.jspa?messageID=5697532] are reasonable starting points for your dual-NIC quest.
One other related gremlin that crops up here is the subnet addressing assignments; you'll usually want to have the (co-resident) NICs using addresses in separate subnets or routing can get squirrelly.
Or plug in the external firewall (which has other advantages) and use it as the router and firewall and NAT box for your LAN.

Hp 1415 network problem

Hello,
I have a strange case with my HP 1415 Printer, before 2 month printer has a network problem, the case that I cannot reach printer IP address from windows machines, I have linux machines and it can ping and print from the printer, I change the printer socket on patch panel and switch but the same, when I remove network cable from the printer and reconnect it it work for few minutes and the problem back, when we leave the printer to next day we find it working well, but onetime it take to days to back to normal, I did firmware upgrade to latest one but the same, I have no idea what is hapening to this printer, and why linux works and windows not.
please help

I assume you are referring to the HP Laserjet CM1415fw printer, correct?
Are you saying that your printer does not maintain a wireless connection? It is connected via ethernet to a networked router, is that right? I want to make sure I fully understand how you have the printer setup.
What is the exact operating system of the Windows computer(s) and how many do you have?
Have you tried installing the software of the printer onto the computers that can not find the printer? Is this the problem you are having or is it that the software is installed but when you press print a) nothing happens? b) you get an error message on the computer that the printer is not connected? c) the printer seems to be frozen and not responding?
To get the proper drivers for your Windows computer, go to www.hp.com/support and select the green box (Drivers and Software) and type in the name of your printer to select the correct operating system of your computer and download the Full Feature Software and Drivers (which I am sure you have done but I just wanted to include it just in case).
Until you answer the above questions, here is a document I think will help you until I get a better understanding of what is wrong.
--Printer Does Not Maintain A Wireless Connection-- You may want to start on Step 4.

Hi mbkrish,
Do you experience the network issue regardless of your area? Aside from calling, are the other network services working fine like SMS messaging and mobile data connection? Is this for a Lumia 520 as well? If so, I hope you're using a standard microSIM and not a cut one as this is what the phone is designed to use.
BTW, the reset that the Nokia Care Center recommended is the one under Settings > about, is that right? After the reset, have you checked if the system apps are updated? Go to Settings > swipe to applications > store > check for updates.
Let us know how it will go.
