tompab Posted July 31, 2003 Report Share Posted July 31, 2003 I work as a System administrator at one of the largest departments of Lund University, Sweden. We have just built up a new Backup System to cover all our 250 employees and 6TB of data. This system is built around an Apple xServ with MacOS X 10.2 and Retrospect Backup Server 5.0.238 to this we have a Storagetek L40 SDLT robot connected. When setting up the clients we have encountered a lot of difficulties that I hope that you can help me with. The first is that most of the clients do not show up in the clients/network window. most of them are within the same building network an connected via switches (no router) but some are in another building on the same subnet but linked via a node. The Lund University subnet is due to the size of the university very large (16 bit) and is the whole x.x.0.0/255.255.0.0 The computers in house are all in the x.x.x.0 series and I have tried to set up subnet brodcasts to the other series. None of the computers from the other building show up in the list and only about 15% of the ones in this building show. All computers can be pinged, have valid IP-addresses and show the Retrospect Ready for first access. About 5-10% of the computers that don't show up can be accessed via typing the IP-number directly in Retrospect server. The computers that can be accessed go on and of line very often and very infrequently. After changing one setting e.g. change password it would say "Sorry can't connect to client error -1028 (client is not visible on network)" After trying for a couple of times it will reappear but then go of line again after some time. Please respond to this as fast as you can because my time is running out and the system is completely unusable as it is right now. I have worked for a week with this and read all there is to read for retrospect, twice! Without finding anything that can help me. Link to comment Share on other sites More sharing options...
shadowspawn Posted July 31, 2003 Report Share Posted July 31, 2003 Quote: All computers can be pinged For one of the local subnet computers, does a long term ping (say an hour) show any packet loss? Do you have problems with servers getting dismounted from clients? (I work in a much smaller network, so don't have first hand experience. It does sound like your network reliability may be an issue. ping is very simple, someone else may suggest a more sophisticated test of your client connectivity!)

garethhughes Posted August 1, 2003 Report Share Posted August 1, 2003 I have the same problem. I have a network of 2 OSX machines linked via a switch. The client machine shows up in the list of backup clients but I get the -1028 message when I try to log in. If the software can see the machine and the client software is up and running and waiting for it's first access, why doesn't it work? This is my first experience with this software and so far I'm not impressed! Can anybody help or do I buy something else? Gareth Link to comment Share on other sites More sharing options...

The client machine shows up in the list of backup clients but I get the -1028 message when I try to log in. Test without the switch. If the Macs are modern models (that have auto-sensing 10/100 Base T ports) you can use a single cable to connect them. Configure your Network settings appropriately (if you need to, create locations with simple IP addresses such as 10.10.1.1 and 10.10.1.2; no other settings necessary). Use a different cable then any of the cables you're using now! If the machines are not modern Macs, you should include the hardware information in your request for assistance. The error you're experiencing points to hardware (a cable is hardware, so is your NIC). Basic troubleshooting can help to isolate and identify where the problem lies.

garethhughes Posted August 2, 2003 Report Share Posted August 2, 2003 OK Dave I tried that but no luck. The server is running on a Powermac G4 933MHz, 768MB and a Gigabit ethernet. The client is running on a PowerBook G4 667MHz, 768MB and a Gigabit ethernet. I've tried with 2 different cables, a cat 5 patch cable and a cat 6 high performance patch cable both made by Belkin. Both machines configured with Manually set IP address as you suggested. I see there is a process called RetroRun running on the server; what is this and should it be there? I can't stop it because it's owned by root. That's about all the information I can find, any more ideas, I've run out now. Gareth Link to comment Share on other sites More sharing options...

Do you have the firewall enabled on either machine? Check Firewall tab of Sharing preference pane. > I see there is a process called RetroRun running on the server; what is this and should it be there? It's the unix daemon that launches Retrospect when it's time for a script to run (it gets its information from /Library/Preferences/Retrospect/RetroRunFile). >I can't stop it because it's owned by root. Not true. It's your machine, you can do anything with it. You can stop any process by typing the following in the Terminal: sudo kill PID (where PID=the Process ID number, as shown in ProcessViewer) Enter your user password at the prompt Link to comment Share on other sites More sharing options...
garethhughes Posted August 3, 2003 Report Share Posted August 3, 2003 Bingo! It was the firewall on the client machine. I've set it up so the right port number (page 216 of the User Guide) is in the list now so all is well. Thanks for your help Dave, I hope this has helped others too.
