Description of problem:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.rhn_register - ensuring that hw and/or sw profiles are selected
Actual Results: RHN server drops connection due to numerous delays and
retransmissions of packets.
Expected Results: Database should include my hw/sw profiles and the task should
have completed successfully.
I have a tcpdump trace showing the packet activity produced during one attempt
to run rhn_register
Created attachment 42715 [details]
Same problem also manifests itself with the 'up2date -p' command (update profiles).
Running a plain 'up2date' also exhibits some the same problems, but the data exchanges are smaller and are thus more likely to succeed - albeit with
numerous packet retries.
I have discovered a VERY temporary work-around for this problem!
sysctl -w net.ipv4.ip_no_pmtu_disc=1
seems to allow my system to register and update profiles - albeit sloooowly.
are you connecting from behind a modem or through a firewall/vpn? This looks
awfully close o an MTU size mismatch (ie, using an MTU that is higher than what
the connection path allows)
Closing this out due to lack of activity.
