Tomcat 5.5.29 does not accept connections from outside
Hi all, I have installed Tomcat 5.5.29 on Windows 2008 as a service. It works fine on the computer where I installed it: http://localhost:8080/, http://localhost:8080/admin, http://localhost:8080/manager/html, http://localhost:8080/myWebApp answer well. But when I try to access it from any other computer of the local private network, I get a Connection failed error, ie. the URLs http://myServer:8080/, http://myServer:8080/admin, etc... do not respond. NB: - the firewall is inactive on the server and on the clients - my configuration is basic: no AJP, no proxy, no cluster, I call Tomcat directly on the default ports - I tried a telnet myServer 8080, which did not work - I tried to install Tomcat 5.5.17 instead of Tomcat 5.5.29, and it worked !! ie. the URLs http://myServer:8080/, http://myServer:8080/admin, etc... DO respond !! Is there a security restriction since Tomcat 5.5.17 ? I read the security archives of Tomcat 5.5, but found nothing. Thanks in advance, Marc. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re : Tomcat 5.5.29 does not accept connections from outside
What happens if you start Tomcat from the startup.bat script intomcat/bin, from a 5.5.29* .zip version? = The same: it works on the computer, but not on the local network = NB: I only unzipped the archive and launched the server: this is the simplest configuration ever. * Why install 5.5 when you can install 6.0? = because I have to: my client wants Tomcat 5.5.29. Anyway, it is a very basic configuration which works with Tomcat 5.5.17, but not with Tomcat 5.5.29. Hi all, I have installed Tomcat 5.5.29 on Windows 2008 as a service.

Thank you for the answer, but I think it is not a network problem: nslookup epigonesrv11 answers correctly on my computer: Nom :epigonesrv11.epigonedom.dom Address: 192.168.0.6 ping epigonesrv11 answers also correctly (with some french in it): Envoi d'une requête 'ping' sur EPIGONESRV11.epigonedom.dom [192.168.0.6] avec 32 octets de données : Réponse de 192.168.0.6 : octets=32 temps1ms TTL=128 Réponse de 192.168.0.6 : octets=32 temps1ms TTL=128 Réponse de 192.168.0.6 : octets=32 temps=1 ms TTL=128 Réponse de 192.168.0.6 : octets=32 temps1ms TTL=128 Statistiques Ping pour 192.168.0.6: Paquets : envoyés = 4, reçus = 4, perdus = 0 (perte 0%), Durée approximative des boucles en millisecondes : Minimum = 0ms, Maximum = 1ms, Moyenne = 0ms But telnet epigonesrv11 8080 answers that connection on port 8080 is impossible: Connexion à epigonesrv11...Impossible d'ouvrir une connexion à l'hôte, sur le port 8080: Échec lors de la connexion As I explained anyway, all the firewalls are inactive, AND I can establish a connection with Tomcat 5.5.17 BUT not with Tomcat 5.5.29.

I tried the windows .exe installers of Tomcat 5.5.17 and Tomcat 5.5.29, and the zip distributions of Tomcat 5.5.17 and Tomcat 5.5.29, and: - my computer contacts Tomcat 5.5.17 on port 8080 (either when installed by a zip or an exe) - my computer does not contact Tomcat 5.5.29 on port 8080 - Tomcat 5.5.29 is running, since it is accessible from the local server (I log on the server, and call http://localhost:8080, and I get the admin console) Hi all, I have installed Tomcat 5.5.29 on Windows 2008 as a service.

DO respond !! contradicts the above. There is a puzzle there.. To find out if there is a problem with name resolution, do this : on the same workstation where you tried the telnet command, enter nslookup myServer it should tell you the IP address of that host. If it does not, you have a DNS issue. To find out if there is a general network issue between the workstation and the server, do ping myServer In general however, instead of saying it did not work, try to be a bit more specific. What exactly happens when you do telnet myServer 8080 Don't be afraid to paste the original error message here, we're polyglots.

Hi, The same as http://epigonesrv11:8080 : it works with Tomcat 5.5.17, but not with Tomcat 5.5.29. Fortunately, the install / uninstall procedure is rather quick ;o) Thx, Marc. -- Marc, what gives if you call http://192.168.0.6:8080?

Does it explain my problem ? Marc, if you start up a command prompt and run: netstat -an | find 8080 ... what do you get?

Hi Charles, You can try setting the address attribute of your Connector elements to 0.0.0.0 to force IPv4. It works, thank you NB: Other people might experience the same problem.

Re : Re : Re : Re : Re : Tomcat 5.5.29 does not accept connections from outside
Hi Jeff, Good guess: I had always the native libraries installed on Tomcat 5.5.29. For Tomcat 5.5.17, it depends: for the 2 firsts installs, I installed the native libraries. But the dll wouldn't download for the next ones, so I pressed cancell, and they didn't install. Anyway, the connection with Tomcat 5.5.17 always worked from outside computers (with and without the native libraries). There was not this download problem with Tomcat 5.5.29: I guess the dll came within the install of Tomcat 5.5.29. I am not at work until monday, I will give you the version numbers then. Sorry for c'est au pied du mur...: I pressed the wrong button. See you, Marc. Marc - Do you have the native libraries installed? What are their releases Tomcat 5.5.17 vs. 5.5.29?
